II. Background, Basis, and Purpose
This rule incorporates by reference
updated marine engineering standards
in Title 46 of the Code of Federal
Regulations (CFR) subchapter F,
including standards for boilers, pressure
vessels, auxiliary machinery, piping,
valves, and fittings, for various types of
vessels. The rule also adds a limited
number of alternative standards and
eliminates outdated or unnecessarily
prescriptive regulations.
The Office of Management and Budget
(OMB) directs, via OMB Circular A–119,
that federal agencies use industry-based
voluntary consensus standards in lieu of
government-unique requirements,
where appropriate. The Coast Guard
actively participates in the development
of industry standards for safety of
marine equipment at the International
Maritime Organization (IMO), the
International Organization for
Standardization (ISO), ASTM
International (ASTM), American Society
of Mechanical Engineers (ASME), and
other standards-setting bodies that
belong to the American National
Standards Institute (ANSI). Recently
published editions of these standards
provide necessary updates to materials,
testing practices, and technologies,
enhancing safety and compliance.
The Coast Guard has statutory
authority to issue regulations under
Title 43, United States Code (U.S.C.),
section 1333(d), 46 U.S.C. 3306 and
3703, and the Department of Homeland
Security (DHS) Delegation No. 00170.1,
Revision No. 01.3, paragraph (II)(92)(b),
which delegates authority under these
statutes to the Commandant of the Coast
Guard. Title 43 of the U.S.C., section
1333(d) grants the Secretary the
authority to promulgate and enforce
regulations with respect to lights and
other warning devices, safety
equipment, and other matters relating to
the promotion of safety of life and
property on artificial islands,
installations, and other devices. Title 46
of the U.S.C., section 3306(a)(1),
authorizes the Secretary to prescribe
regulations for the design, construction,
alteration, repair, and operation of
vessels subject to inspection, including
equipment, appliances, propulsion
machinery, auxiliary machinery, boilers,
unfired pressure vessels, piping, and
electric installations. Additionally, 46
U.S.C. 3703(a) grants the Secretary
authority to regulate tank vessels
regarding the construction, alteration,
repair, maintenance, operation, and
equipping of vessels that may be
necessary for increased protection
against hazards to life and property, for
navigation and vessel safety, and for
E:\FR\FM\12JNR2.SGM

Federal Register / Vol. 89, No. 114 / Wednesday, June 12, 2024 / Rules and Regulations
enhanced protection of the marine
environment.
On October 19, 2021, the Coast Guard
published a notice of proposed
rulemaking (NPRM) titled ‘‘Updates to
Marine Engineering Standards,’’ (86 FR
57896) requesting comments on the
proposed changes implemented by this
final rule, including several updates to
the standards incorporated by reference.
A detailed description of the
background and proposed changes is
available in that NPRM.
III. Discussion of Comments
During the 60-day comment period for
the NPRM, beginning on October 19,
2021, the Coast Guard received a
comment requesting an extension of the
comment period. The Coast Guard
granted this request, and, on December
20, 2021, published an extension of the
comment period (86 FR 71864), for 45
days, until February 3, 2022. During the
extended comment period, we received
two comments. The comments can be
viewed in the docket following the
instructions in the ADDRESSES section of
this preamble. We summarize the
comments and our responses in the
following sections, starting with general
comments then moving to specific
comments.
ddrumheller on DSK120RN23PROD with RULES2
A. General Comments on the Proposed
Rule
We received two comments
supporting 1 the update of many of the
standards proposed for incorporation by
reference (IBR) in subchapter F,
emphasizing the importance of
‘‘referencing the latest editions of
widely used consensus standards.’’ Both
comments also supported the addition
of alternative standards and the
elimination of outdated or unnecessarily
prescriptive regulations. We thank the
commenters for their support of this
update to subchapter F.
B. Editorial Comments on the Proposed
Rule
Comment: Two commenters
recommended that, for the sake of
clarity, proposed 46 CFR 56.60–1(a)(2)
be turned into a multiple-paragraph list.
The same commenters stated that the
reference to table 56.60–1(b) in § 56.60–
1(b) appears erroneous and should
probably refer to table 2 to § 56.60–1.
Response: We agree and have
reorganized § 56.60–1(a)(2) so that it
1 One commenter provided a lengthy statement
detailing its full support of the proposed updates,
while the other commenter endorsed the first
commenter’s statement. When we use ‘‘both
comments’’ we mean either both comments
explicitly, or the first comment as supported by the
second.

now constitutes new § 56.60–1(a)(2)
through (4). We have revised the table
reference in § 56.60–1(b) to conform
with other updates to table numbering
as proposed in the NPRM.
C. Substantive Comments on Standards
Within the Proposed Rule
Comment: Two commenters
recommended that the Coast Guard
continue the IBR of ASME B16.10, Faceto-Face and End-to-End Dimensions of
Valves, which we proposed to remove
in the NPRM.
Response: Because ASME B16.10 is
already referenced in ASTM F1155,
which we proposed for IBR in the
NPRM, in practice ASME B16.10 will
continue to be incorporated by reference
even if it is not specifically mentioned.
Specifically incorporating ASME B16.10
is redundant when the standard and its
requirements are provided within
ASTM F1155.
Comment: Two commenters
recommended the following standards
be incorporated by reference in Part 56:
• American Petroleum Institute (API)
standard API Spec 6D, Specification for
Pipeline and Piping Valves, 25th
Edition;
• ASTM B148–18, Standard
Specification for Aluminum-Bronze
Sand Castings; and
• ASTM D2996–17, Standard
Specification for Filament-Wound
‘‘Fiberglass’’ (Glass-Fiber-Reinforced
Thermosetting-Resin) Pipe.
Response: Because ASTM D2996 is
already referenced within ASTM F1155,
which we incorporate by reference by
means of this final rule, it is not
necessary to duplicate the reference.
With regards to ASTM B148 and API
Spec 6D, these standards are neither
currently referenced within subchapter
F, nor were they proposed for IBR in the
NPRM. We recognize that there are
numerous national and international
standards that provide similar
requirements and equivalent
performance for the same equipment or
system. Naval architects and system
designers may submit for approval
components designed to alternative
standards that provide an equivalent
level of safety in accordance with the
provisions of 46 CFR 50.20–30.
Comment: We received two comments
recommending against incorporating by
reference API Recommended Practice
14C, Analysis, Design, Installation, and
Testing of Safety Systems for Offshore
Production Facilities, Eighth Edition,
February 2017 (which would update the
current incorporation by reference
within subchapter F of an earlier edition
of this standard), and API STD 53, Well
Control Equipment Systems for Drilling
PO 00000
Frm 00003
Fmt 4701
Sfmt 4700
50059
Wells, 5th Edition (which would replace
a superseded standard currently
incorporated by reference within
subchapter F). The commenters
expressed concern that, since the June 4,
2013, Memorandum of Agreement
between the Coast Guard and the
Bureau of Safety and Environmental
Enforcement (BSEE) designates BSEE as
the lead agency for safety and
operations on outer continental shelf
(OCS) facilities, and the referenced
standards are already included in BSEE
regulations, including them in
subchapter F as well could create a risk
of edition conflict between BSEE and
the Coast Guard. For the same reason,
the commenter recommended removing
the entirety of subpart 58.60—Industrial
Systems and Components on Mobile
Offshore Drilling Units (MODUs), and
using the standards incorporated by
reference in 30 CFR 250.198 for
industrial systems and components as
well as marine systems and components
for all oil and gas facilities on the OCS.
Response: We have elected to retain
these standards in subchapter F and not
remove subpart 58.60 from the CFR, in
order to maintain clarity regarding
requirements for engineering systems.
The ship and facility marine
engineering and electrical systems that
the Coast Guard regulates interface with
industrial systems under the
jurisdiction of BSEE. The Coast Guard
and BSEE have a shared mission of
ensuring safety on the OCS. We work
together closely to ensure our
requirements are not in conflict.
Comment: We received a comment
regarding the IBR of the American
Bureau of Shipping (ABS) standard,
ABS Rules for Building and Classing
Marine Vessels, 2020, Part 4, Vessel
Systems and Machinery, which we
proposed in the NPRM as an update of
the earlier 2003 standard already
incorporated in subchapter F. The
commenter argued that ‘‘incorporating
the classification rules of [ABS] in
subchapter F (and 46 CFR Chapter I)
uses the rules of one classification
society to set a regulatory baseline,
which could competitively disadvantage
other societies and deprive the industry
of knowledge and innovation available
in other societies’ rules.’’
Response: We appreciate the
comment, but do not agree. Many
vessels normally subject to the
regulations of subchapter F are enrolled
in the Alternate Compliance Program
(ACP), where the rules of any
recognized classification society may be
used in lieu of the requirements of
subchapter F. Given that the rules of
other recognized classification societies
are already in wide use through the ACP

12JNR2
50060
Federal Register / Vol. 89, No. 114 / Wednesday, June 12, 2024 / Rules and Regulations
and will remain so, the IBR of the ABS
standards will not disadvantage other
classification societies or interfere with
the sharing of expertise throughout the
industry. We discussed this in depth in
‘‘Discussion of Proposed Rule’’ in the
NPRM.2
ddrumheller on DSK120RN23PROD with RULES2
D. Comments Recommending
Additional Regulatory Action
Comment: Two commenters
recommended updating 33 CFR
subchapter N to clarify the applicability
of the rule to existing and new floating
OCS facilities, nearly all of which are
not, properly speaking, ‘‘vessels’’ or
‘‘ships.’’ The commenters also
recommended that the Coast Guard act
on the March 28, 2018, National
Offshore Safety Advisory Committee
(NOSAC) Production Subcommittee
Final Report on [U.S. Coast Guard]
Regulatory Reform recommendation that
‘‘The Coast Guard should issue NOSAC
a new Task Statement to evaluate the
suitability of the regulations in 46 CFR
Subchapter F (Marine Engineering) and
46 CFR Subchapter J (Electrical
Engineering) to floating OCS
facilities.’’ 3 The commenters suggested
that, since floating OCS facilities are
not, properly speaking, ‘‘vessels’’ or
‘‘ships,’’ the application of subchapter F
to such facilities has led to multiple
requests for equivalencies and
alternatives, and that while the Coast
Guard has attempted to address this via
policy letter,4 this policy letter only
applies to floating OCS facilities classed
with a classification society.
The commenters suggested that, at a
minimum, the Coast Guard should
update 33 CFR 143.120 to establish the
date on which this rule would apply to
a new floating OCS facility.
Response: An update to 33 CFR
subchapter N regarding its applicability
to floating OCS facilities and a
statement on the same issue to NOSAC
are outside the scope of this rulemaking
but could be addressed in a future
rulemaking. We encourage questions
regarding the applicable regulations for
floating OCS facilities to be sent either
to the Coast Guard’s Eighth District
Outer Continental Shelf Division Staff
(website: https://www.atlanticarea.
uscg.mil/D8/OCS) or the Outer
Continental Shelf National Center of
Expertise (OCSNCOE) (website: https://

update to 33 CFR 143.120, the date that
33 CFR subchapter N requires
compliance with subchapter F is the
effective date, 90 days after the
publication of this final rule.
E. Comments Recommending
Additional Non-Regulatory Action
Comment: Two commenters
supported the proposed IBR of ASTM
F1155–10 (Reapproved 2015), Standard
Practice for Selection and Application
of Piping System Materials, but also
recommended the Coast Guard’s Marine
Safety Center (MSC) cancel Marine
Safety Center Technical Note (MTN) 02–
10, Material Selection for Vital Piping
Systems, as superseded by the adoption
of this standard.
Response: We generally agree, but we
note that ASTM F1155 has application
to all shipboard piping systems, while
MTN 02–10 is focused on ‘‘vital’’
shipboard systems. MTN 02–10 will be
reviewed and revised if necessary.
F. Comments on the Regulatory Analysis
(RA)
Comment: Two comments expressed
concern that table 3 of the RA did not
specifically address floating OCS
facilities and did not provide enough
clarity to determine if floating OCS
facilities were included within the table.
The commenters recommended that the
Coast Guard undertake changes to the
Marine Information for Safety and Law
Enforcement (MISLE) system and its
internal documentation to eliminate any
confusion regarding the inclusion or
exclusion of floating OCS facilities, not
only for the purpose of this rule but also
for future Coast Guard regulatory
actions.
Response: We agree with these
comments. In our MISLE database,
floating production systems are listed as
being inspected under 46 CFR
subchapter I–A; this is incorrect, and, as
a result, we overstated the number of
MODUs in the RA, which lowered the
population of vessels in the ‘‘Industrial
Vessel’’ category. After further analysis
we revised the population of MODUs to
one, because we incorrectly classified
the remainder based on the subchapter
inspection field in MISLE. The Coast
Guard will amend its MISLE database to
correctly label these vessels.
While we did update table 4 of the RA
in response to public comments, we did
not receive feedback from the public
that would impact our estimate of the
number of equivalency requests that are
submitted to the Coast Guard on an
annual basis. Therefore, the regulatory
assessment of costs, cost savings, and
benefits of the NPRM remain
PO 00000
Frm 00004
Fmt 4701
Sfmt 4700
unchanged, other than the use of more
current economic data, where available.
Comment: We also received two
related comments regarding the number
of specific vessel types, suggesting that
the listing of 110 MODUs in table 3 of
the RA was not accurate and that there
are fewer than 5 U.S.-flagged MODUs in
active service.
Response: We agree with these
comments. As stated above, in the RA
for the proposed rule, we incorrectly
labeled ‘‘floating production systems’’
and counted them as MODUs. This
overstated the number of MODUs
because these systems are incorrectly
listed in MISLE as being inspected
under title 46 CFR subchapter I–A. After
further analysis, we revised the
population of MODUs for the final rule
to one, because we incorrectly classified
the rest based on the subchapter
inspection field in MISLE. Floating
production systems are facilities
certificated and inspected under 33 CFR
subchapter N and not vessels inspected
under 46 CFR subchapter I. We
overestimated the number of affected
vessels in the proposed rule; therefore,
in this final rule we revise the number
of vessels in the subchapter I from 6,086
down to 623. Because we updated the
entire population for this final rule, the
total number of vessels and facilities is
revised down from 16,148 in the
proposed rule to 5,655 (see table 4 in
this document).
IV. Discussion of Rule
A. General Discussion
In order to decrease the likelihood of
introducing errors, to improve efficiency
during the publication process, and to
meet drafting and formatting
requirements for publication, we are
revising or revising and republishing
entire sections, subparts, and parts, as
appropriate. Except as explained as a
change in this preamble, the individual
(piecemeal) changes are detailed in the
proposed rule, published on October 19,
2021 (86 FR 57896).
In general, the rule makes the
following changes:
1. Corrections—we amend several
sections to correct inadvertent errors or
deletions. We also remove material that
is obsolete or superfluous, and update
contact information for Coast Guard
offices and standards organizations.
2. Stylistic Revisions—we revise the
language of some sections, primarily for
greater clarity. This includes revising
sentences containing the word ‘‘shall’’
to use ‘‘must’’ or another grammatically
equivalent word or phrase in
accordance with plain language
guidelines. We also standardize terms
E:\FR\FM\12JNR2.SGM
12JNR2
Federal Register / Vol. 89, No. 114 / Wednesday, June 12, 2024 / Rules and Regulations
that were variously presented as
compound words, hyphenated
constructions, or multi-word phrases
using the format preferred by the
Government Publishing Office.
3. Updated cross references—we
update cross references to reflect the
relocation within the CFR of pertinent
provisions. We also standardize
designations for tables, figures, notes,
and formulas using the format preferred
by the Office of the Federal Register
(OFR).
4. Updated industry standards—we
update cross-references to industry
standards by adding new references,
replacing references to superseded
standards or editions, and by
conforming text accordingly. We
incorporate these updated standards
because they reflect the latest available
technologies, practices, and procedures
that are recommended by consensus
bodies, ship classification societies, and
other maritime organizations with
experience in the industry. As the
baseline upon which other standards,
rules, and equivalency requests are
evaluated, it is important that
subchapter F incorporate up-to-date
references. The class rules of ABS, in
particular, are incorporated by reference
in multiple locations within subchapter
F and 46 CFR chapter I.
It is important to note that, while
these rules set the regulatory baseline or
50061
standard for specific engineering
systems and equipment, the Coast
Guard has also authorized classification
societies in accordance with 46 CFR
part 8. These authorized classification
societies are listed on the Coast Guard
website 5 and have been delegated the
authority to perform certain functions
and certifications using their respective
class rules for vessels enrolled in the
ACP. For vessels not enrolled in the
ACP, the class rules of an authorized
classification society may be proposed
as an alternative to the ABS class rules
incorporated by reference for
engineering systems and equipment.

amend, and why.

B. Standards Incorporated by Reference
To Be Updated or Added
Following this paragraph, we include
an alphabetical list of the standards we
are updating or adding, each with a
listing of the sections in which they
appear in 46 CFR. For each standard
listed, we describe the topics covered by
the standard, the changes to the
standard, any difference between the
older edition of standards currently
included within the CFR via IBR and
the edition adopted, and a list of
subparts or sections that reference the
standard.
• ABS Rules for Building and
Classing Marine Vessels, Part 4, Vessel
Systems and Machinery, January 2020.
This standard updates the 2003
standard, incorporated by reference in

58.25–5, 62.25–30, 62.35–5, 62.35–35,
62.35–40, 62.35–50, and 62.50–30. In
2020, ABS changed the name of the
Steel Vessel Rules to Marine Vessel
Rules. All parts and sections contain the
same information along with updates to
reflect the current technologies for
commercial vessels. The rules contain a
comprehensive set of construction and
maintenance requirements for ships and
offshore facilities.
• ABYC P–1–14, Installation of

E. Additional Changes From the NPRM
In addition to the changes discussed
above, we are making further editorial
changes from the text proposed in the
NPRM, as follows.
In § 56.30–20(d), correcting an
erroneous Fahrenheit to Celsius
conversion. The Fahrenheit temperature
currently provided in the CFR is correct.
In § 56.50–60(n), restoring the word
‘‘flammable,’’ as it was inadvertently
deleted.
In § 56.50–70(e), clarifying that the
openings indicated in this paragraph are
openings for fuel tanks.
In § 56.50–75(b)(1), adding ‘‘seamless
steel’’ to the list of acceptable materials.
Seamless steel has always been
acceptable under this paragraph as an
‘‘other material,’’ but, because it is
commonly used, we are adding it to the
list for clarity.
In § 56.50–75(b)(6), removing the
words ‘‘on vessels less than 100 gross
tons and tank barges’’ as unnecessary
because this applicability condition is
already specified in § 56.50–75(b).
In § 56.50–95(f), removing redundant
text relating to prohibitions on the use
of heat-sensitive materials.
In Table 2 to § 56.50–105, removing
footnote 2 and renumbering the
remaining footnotes. Footnote 2
redirected readers to part 54 for
additional information, and all the
necessary information is found in the
table. Deleting cross-references to table
1 to § 56.85–10(c) as we are removing
that table, as discussed below.
In § 56.60–1, relocating note 1 to table
1 to § 56.60–1(a) to follow the table
rather than precede it and redesignating
the other note as note 2 to table 1 to
§ 56.60–1(a).
Reorganizing the information in table
1 to § 56.60–2 and its associated
footnotes to ensure all substantive
requirements are found in the table
itself and renumbering the remaining
footnotes.
In § 56.85–10, revising the text and
removing table 1 to § 56.85–10(c) to
simplify the information presented and
focus on the incorporated standard,
PO 00000
Frm 00022
Fmt 4701
Sfmt 4700
ASME B31.1. The relevant information
regarding heat treatment of welds is
already provided by ASME B31.1 and it
is unnecessary to supplement the text
with additional Coast Guard
requirements that are redundant to
ASME B31.1. In addition, removing a
cross-reference to table 1 to § 56.85–
10(c) in § 56.50–105, as noted above.
As with § 56.85–10, revising the text
in § 56.85–15 to remove unnecessary
supplementary information regarding
post-heat treatment of welds and,
instead, directing readers to follow the
relevant section and table of the
incorporated standard, ASME B31.1.
In § 56.95–10 (a)(1), correcting an
Imperial unit/Metric system unit
conversion that is incorrect in the
current CFR.
In § 58.05–1(b), removing the
requirement for drawings to be
submitted in quadruplicate because
drawings are typically submitted under
this section electronically, making
multiple copies unnecessary.
In § 58.16–10(e), removing the
requirement for plans to be submitted in
triplicate because plans are typically
submitted under this section
electronically, making multiple copies
unnecessary.
Restoring § 58.25–25(a) and (e), with
minor stylistic changes, as these
paragraphs were inadvertently deleted.
In § 58.50–1(b), removing the text
‘‘converted on or after July 1, 1935’’
because the emergency systems
requirements under this section now
apply to all ships.
Reorganizing the information in table
1 to § 62.35–50 and its associated
footnotes to ensure all substantive
requirements are in the table itself and
renumbering the remaining footnotes.
In § 62.50–20(g)(2), correcting a
drafting error by changing the reference
to ‘‘§§ 111.12–11(g) and 111.30–1 of this
subchapter’’ to read ‘‘§§ 111.12–11(g)
and 111.30–1 of this chapter.’’ The
referenced sections are in the same
chapter as § 62.50–20(g)(2), but not the
same subchapter.
In § 64.2, removing the incorporation
by reference of section VIII of the ASME
BPVC, 1974 edition, as it is only
relevant as the source for a constant
used in a calculation in § 64.63. The
actual value of the constant, given in
that section, is sufficient for the
calculation.
In § 64.63, removing the reference to
the 1974 edition of section VIII of the
ASME BPVC as the source of the value
of constant C used in calculating total
emergency venting capacity. The source
of constant C is not required for this
calculation, and as noted above we are
removing the incorporation by reference

this part.
V. Incorporation by Reference
Material for incorporation by
reference appears in 46 CFR parts 50,
52, 53, 54, 56, 57, 58, 59, 61, 62, 63, and
64 and is summarized in section IV.B of
this preamble. Copies of the material are
available either at the publisher’s web
address listed in the incorporation by
reference sections in 46 CFR parts 50,
52, 53, 54, 56, 57, 58, 59, 61, 62, 63, and
64 or by contacting the publisher listed
for those standards. We reviewed and
updated all the publisher’s web
addresses listed in the parts to ensure
they are current. You may also contact
the person in the FOR FURTHER
INFORMATION CONTACT section for
additional direction on how to obtain
access to electronic copies of the
materials.
Based on the volume of equivalency
requests the Coast Guard receives asking
us to confirm that the latest edition is
equivalent to or better than the edition
currently incorporated, we believe
industry already has access to and uses
these more recent standards. The
affected industry typically obtains the
more recent editions of standards in the
course of their business in order to
address advancements in technology.
The Director of the Federal Register
approved the material in 46 CFR parts
50, 52, 53, 54, 56, 57, 58, 59, 61, 62, and
63 for incorporation by reference under
5 U.S.C. 552 and 1 CFR part 51.
We developed this rule after
considering numerous statutes and
Executive Orders related to rulemaking.
A summary of our analyses based on
these statutes or Executive Orders
follows.
A. Regulatory Planning and Review
Executive Orders 12866 (Regulatory
Planning and Review), as amended by
Executive Order 14094 (Modernizing
Regulatory Review) and 13563
(Improving Regulation and Regulatory
Review) direct agencies to assess the
costs and benefits of available regulatory
alternatives and, if regulation is
necessary, to select regulatory
approaches that maximize net benefits
(including potential economic,
environmental, public health and safety
effects, distributive impacts, and
equity). Executive Order 13563
emphasizes the importance of
quantifying costs and benefits, reducing
costs, harmonizing rules, and promoting
flexibility.
As OMB has not designated this rule
a significant regulatory action under
section 3(f) of Executive Order 12866, as
amended by Executive Order 14094, it
has not reviewed this regulatory action.
An RA follows.
The Coast Guard received four public
comments on the affected population in
the RA for the proposed rule. Two of
these comments stated that the RA in
the NPRM did not provide clarity on the
inclusion of OCS facilities. We also
50079
received two comments, with
essentially the same content, stating that
the suggested listing of 110 MODUs in
table 3 of the RA in the NPRM was
incorrect. We discuss our responses to
these comments in section III.F of the
preamble of this final rule. We are
incorporating the commenters’
suggestions into the RA for this final
rule and are revising the population of
MODUs and Cargo and Miscellaneous
Vessels based on MISLE Data.
We are also revising our affected
population estimate from 16,148 vessels
and facilities to 5,655. While preparing
this final rule we obtained the most
current data from the MISLE database,
and determined we likely overcounted
in our analysis in the NPRM (see
Affected Population section for
details).6 Additionally, we updated the
mean hourly wage rate for private sector
workers and Coast Guard military and
civilian personnel using 2022 data.
Furthermore, we updated the load factor
used to account for non-wage benefits
for private sector employees by using
Q4 2022 U.S. Department of Labor’s
Bureau of Labor Statistics (BLS) data
instead of Q4 2020 BLS data. We further
revised the load factor for civilian Coast
Guard marine engineers from 1.75 to
1.69 to be consistent with other recently
published rulemakings from the Coast
Guard’s Office of Design and
Engineering Standards (CG–ENG). We
present a summary of changes to the RA
from the NPRM to the final rule in table
2, below.

Final rule
Reason for change
Resulting change in RA
Affected population of U.S.flagged vessels and facilities.
The Coast Guard estimated
that the rule affected 16,148
vessels and facilities and
6,437 owners and operators.
In the final rule, we revised this
estimate down to 5,655 vessels and facilities.
Hourly wage rates for private
sector and for Federal Government civilian and uniformed personnel.
The NPRM used BLS Occupational and Employment Statistics, Office of Personnel
Management (OPM) General
Schedule (GS) Pay Tables,
and Commandant Instruction
U for calendar year 2020.
The NPRM used BLS Employer Cost for Employee
Compensation data for Q4
2020 for private-sector employees.
The NPRM used a load factor
of 1.75 for civilian Coast
Guard marine engineers.
The final rule uses BLS Occupational and Employment
Statistics, OPM GS Pay Tables, and Commandant Instruction W for calendar year
2022.
We performed a new data pull
of the affected population
and determined that the
NPRM affected population
estimate was likely incorrect.
Availability of more recent data
No change because the RA
does not directly use the affected population in calculations but instead uses
equivalency requests.
Data directly affects the calculation of projected cost
savings.
Availability of more recent data
Encourage consistency across
recent rulemakings involving
the same category of Coast
Guard civilian employees.
Data directly affects the calculation of projected cost
savings.

Federal Register / Vol. 89, No. 114 / Wednesday, June 12, 2024 / Rules and Regulations
With this final rule, the Coast Guard
updates 46 CFR subchapter F. This final
rule aligns the standards for U.S.-flagged
vessels and facilities in subchapter F
with current industry practices to
ensure that regulatory requirements are
consistent with current industry
standards. Most of the updates simply
incorporate by reference the more recent
versions of the same standards with
little or no substantive change. In some
cases, the more recent editions reflect
more modern technologies, terminology,
and practices. The updates also correct
regulatory language and remove
redundant and outdated references. The
Coast Guard finds no additional costs
associated with this rule and estimates
this rule saves the regulated public and
the Federal Government approximately
$9.762 million over the 10-year period
of analysis, discounted at 7 percent and
in 2022 dollars. The total annualized
cost savings are an estimated $1.390
million, discounted at 7 percent and in
2022 dollars.
The following RA provides an
evaluation of the economic impacts
associated with this final rule. Table 3
provides a summary of the rule’s costs
and benefits.

The Coast Guard analyzed the impacts
of the final rule to determine the
affected population and how the rule
affects vessel and facility owners and
manufacturers. The engineering updates
for subchapter F potentially affect the
vessels and facilities inspected under
the following subchapters: D ‘‘Tank
Vessels;’’ H ‘‘Passenger Vessels;’’ I
‘‘Cargo and Miscellaneous Vessels;’’ I–A
‘‘Mobile Offshore Drilling Units;’’ L
‘‘Offshore Supply Vessels;’’ O ‘‘Certain
Bulk Dangerous Cargoes;’’ O–I
‘‘Combination Bulk Cargo;’’ O–D
‘‘Combination Bulk Cargo-including
chemicals;’’ R ‘‘Nautical Schools;’’ U
‘‘Oceanographic Research Vessels;’’ and
41 floating production systems
(facilities) in 33 CFR subchapter N
‘‘Outer Continental Shelf Activities.’’ 9
Because the rule impacts only new
vessels or those undergoing major
conversions, we estimate that fewer
than 200 vessels will be impacted
annually.10
We estimate the final rule affects
about 5,614 vessels and 41 facilities
owned by approximately 952 owners
and operators. The rule directly impacts
vessel owners or operators procuring a
new vessel or engaging in a major
conversion of an existing vessel under
conditions specified in the rule. Large
self-propelled vessels generally have a
greater number of complex engineering
systems covered in subchapter F than
smaller vessels or barges. With the
updates to engineering standards in this
final rule, we expect, therefore, that
large self-propelled vessels are more
likely to be impacted.
In the NPRM for this rulemaking, we
significantly overcounted the number of
vessels subject to subchapter F because
two categories of vessels in MISLE that
do not have distinct 46 CFR
subchapters, ‘‘industrial vessels’’ and
‘‘tank barges,’’ were incorrectly assumed
to be subject to subchapter F’s marine
engineering requirements in all cases.
Subchapter F is generally applicable
only to larger vessels such as cargo
ships, large passenger vessels, and tank
vessels, so many vessels in the
categories mentioned above are not
subject to its requirements. In addition,
because cargo and tank barges are not
self-propelled, and subchapter F
primarily focuses on vital engineering
systems such as propulsion and steering
systems, much of subchapter F is not
applicable to barges.
In this final rule we revise the
population estimate, as shown in table
4 below. The total affected population of
vessels and facilities is reduced from
16,148 in the proposed rule to 5,655 in
the final rule. However, vessels are
generally subject to the regulations in
effect at the time of ship construction.
Therefore, only vessels constructed
subsequent to the effective date of this
final rule will be subject to its
requirements, so our estimate of the
average number of new vessels entering
service annually (provided in the last
row of table 4) provides a much more
realistic picture of the affected
population of this final rule than does
the total universe of vessels subject to
subchapter F.
7 The rule continues the Coast Guard’s response
to the Presidential Regulatory Reform Initiative of
March 4, 1995, and directives including Executive
Orders 12866 and 13563 that are intended to
improve regulation and the regulatory process. The
provisions of this rule remove outdated regulations,
revise current regulatory text, and incorporate by
reference more recent national and international
industry standards into the CFR. The Coast Guard
recognizes the significant technological advances
technology and equipment which is used or carried
on vessels. As a result, this rule encourages the use
of newer equipment and promotes adherence to
modern standards in the industry.
8 We present a full list of corrections in table 1
of the preamble.
9 We excluded public vessels from the
population.
10 Based on input from Coast Guard subject matter
experts with relevant technical expertise in the
Office of Design and Engineering Standards (CG–
ENG).
The objective of the final rule is to
update design standards in 46 CFR
subchapter F by incorporating by
reference more recent industry
standards. The final rule provides
clarity, simplifies regulatory compliance
for industry with the removal of
obsolete regulations, and revises current
regulatory text, which includes the
correction of errors.8

The rule also affects businesses
involved in vessel or facility
manufacturing. There are approximately
83 shipyards and manufacturers of
vessels or vessel components in the
affected population. However, the Coast
Guard believes that because equipment
and vessel manufacturers participate in
the development and revision of marine
industry standards and ship design
requirements, manufacturers are already
in voluntary compliance with the
changes. In addition, the rule affects the
Coast Guard and its staff in the MSC and
CG–ENG. The rule impacts an estimated
six civilian engineers and six military
engineers.

Summary of Changes Adopted for the
Final Rule
In this final rule, the Coast Guard
adopts the changes included in the
NPRM, which update the codified
references to standards incorporated by
reference in subchapter F with their
more recent editions. More specifically,
the changes in the final rule fall into
three categories: (1) editorial changes to
the CFR, (2) technical updates to
standards incorporated by reference,
and (3) compliance alternatives to
standards incorporated by reference.
Based on data from industry, the Coast
Guard assumes industry already uses
the more recent standards referenced in
the rule.
First, this final rule makes editorial
changes to 46 CFR subchapter F (parts
50, 52, 53, 54, 56, 57, 58, 59, 61, 62, 63
and 64) that include such items as the
removal of outdated terminology and
the consolidation of text. These changes
have no costs or cost savings associated
with them.
Second, this rule updates standards
incorporated by reference throughout
subchapter F. Because no resources are
VerDate Sep<11>2014
18:22 Jun 11, 2024
Jkt 262001
required, and because they have already
been adopted voluntarily by
manufacturers, these changes have no
cost associated with them.
Third, this rule amends the regulatory
text in 46 CFR 58.10–5(d)(1) and 61.10–
5(g) impacting compliance alternatives
for vessel and facility owners or
operators. The changes reflect the
addition of one compliance alternative
and the removal of another. This change
results from the discontinuation of a
standard incorporated by reference that
is the basis of the compliance
alternative. (Please see Section IV.D. in
the preamble under the discussion,
‘‘Part 61—Periodic Tests and
Inspections,’’ and further details in the
‘‘Cost Savings’’ portion of this RA.)
These changes provide regulatory
flexibility for the regulated public. The
final rule imposes no additional costs
on industry, and the addition of a
compliance alternative in § 61.10–5(g)
may save the regulated public money
and generate cost savings for vessel and
facility owners or operators if they
choose to use this compliance
alternative.
The final rule promotes consistency
between Coast Guard regulations and
national and international standards
through incorporation by reference,
provides options with alternative
standards, eliminates obsolete
standards, and clarifies the existing
requirements through the changes in 46
CFR subchapter F. Readers may consult
the preamble of this rule for a general
summary of the changes.
The final rule adopts the regulatory
changes in the proposed rule.
Additionally, based on feedback from
the public during the comment period,
the rule reorganizes 46 CFR 56.60–
1(a)(2) and adds 46 CFR 56.60–1(b) for
the purpose of regulatory clarity. These
PO 00000
Frm 00025
Fmt 4701
Sfmt 4700
changes are editorial in nature and do
not impose costs on or create cost
savings for industry.
Data Input for Calculations
This RA uses multiple data sources.
We estimated the duration of tasks and
determined the relevant personnel with
input from Coast Guard subject matter
experts within CG–ENG.
The Coast Guard obtained wage data
from three publicly available sources.
First, for Coast Guard military
personnel, we used the Coast Guard
Commandant Instruction entitled
‘‘Reimbursable Standard Rates’’
(commonly called Commandant
Instruction W).11 Second, for Coast
Guard civilian personnel we used
OPM’s GS hourly rates for the
Washington, DC, locality pay area for
2022.12 Third, for workers outside of the
Federal Government, we used the BLS
Occupational Employment and Wage
Statistics dataset for 2022 for private
sector wage rates.
To estimate the actual cost savings of
labor to employers, the Coast Guard
determined the loaded wage rates of
each type of occupation (military,
civilian in Government, and civilian out
of Government) affected by the final

rule.13 Commandant Instruction W
presents loaded wage rates; therefore,
we did not apply a load factor
adjustment for Coast Guard military
personnel. However, for Coast Guard
civilian personnel and for private sector
workers outside of the Federal
Government, we multiplied the wage
data obtained in the previous step by a
load factor to estimate the loaded wage
rates for these employees. We calculated
the load factors to apply to Coast Guard
civilian employees from total
compensation and wage data in the
2017 Congressional Budget Office (CBO)
report ‘‘Comparing the Compensation of
Federal and Private-Sector Employees,
2011 to 2015.’’ We calculated the load
factor to apply to private sector workers
from BLS’s ‘‘Employer Cost for
Employee Compensation’’ dataset for
the fourth quarter of 2022.
Costs
The Coast Guard finds no costs
associated with this final rule. The rule
does not require actions of
manufacturers nor vessel and facility
owners or operators. The rule is not
retroactive, and existing vessels are not
required to be retrofitted.
This rule does not require owners or
operators to acquire any standards
incorporated by reference; they will not
need the standard in hand to comply.
Owners and operators need only look
for evidence from manufacturers that
vessels or facilities meet or exceed the
standard before purchase; such evidence
could be found in a contract for
purchase or repair of a vessel or facility
or in product documentation such as a
user guide or warranty information. For
these reasons, the Coast Guard has not
included a cost for the procurement of
the newer standards for vessel and
facility owners or operators.
The Coast Guard estimates that the
regulated public (manufacturers) are
currently in voluntary compliance with
the requirements of the rule based upon
manufacturer participation in the
development of industry standards.
When standards organizations formulate
industry standards, the standards
undergo a process of review and
comment by the industry. Input from
manufacturers is key to developing new
standards that consider the engineering
capabilities of manufacturers. After the
review and comment process, the newer
standard is voted upon at the various
governing bodies’ committee meetings,
and manufacturers are among those

pays per hour to employ a person, not the hourly
wage an employee receives. The loaded hourly
wage rate includes the cost of non-wage benefits

voting. For this reason, the Coast Guard
believes manufacturers are aware and
knowledgeable about the newer
standards. Given this, we further
assume they already own copies of the
standards and, therefore, have not
computed a cost for them to procure the
standards incorporated by reference.
Manufacturers have already been
producing equipment to meet the
standard, and typically begin to make
manufacturing modifications even
before such changes are adopted
formally. Therefore, the Coast Guard
does not anticipate that there will be
costs to retrofit manufacturing
equipment to comply with the final
rule. For previous similar rulemakings,
no manufacturers commented that they
would experience incremental costs of
production to comply with newer
editions of standards incorporated by
reference.14 For these reasons, the Coast
Guard has not included a cost for these
provisions. However, the Coast Guard
acknowledges that some manufacturers
may need to purchase a newer standard.
The estimated incremental cost to do so
varies according to which standard is
needed.15
Cost Savings
By amending 46 CFR subchapter F,
this final rule eliminates confusion from
outdated and conflicting rules on
marine engineering safety for various
vessel or facility components and
systems and gives the maritime industry
clear instructions on how to comply
with regulations. Moreover, this final
rule amends existing regulations to
reflect current national and
international standards. The final rule
also generates cost savings to the
regulated public and the Federal
Government.
Several of the rule’s changes have no
cost or cost savings impact. These
editorial changes, such as the removal of
outdated terminology and the
consolidation of text, clarify regulations
but do not result in cost savings, as
noted earlier. Also, by incorporating the
newer standards, the changes provide
clarity and specificity. The Coast Guard
14 A similar rulemaking is the Revision of Crane
Regulation Standards for Mobile Offshore Drilling
Units, Offshore Supply Vessels, and Floating Outer
Continental Shelf Facilities proposed rule,
published May 13, 2013 (78 FR 27913) (Docket
Number: USCG–2011–0992).
15 We estimate the cost to acquire a standard by
the equation (0.25 hour × supervisory wage rate +
0.5 hour × admin assistant wage rate + cost of
purchasing a copy of the standard + shipping cost).
We base this equation on the publicly vetted cost
estimation in the regulatory analysis for the rule
Revision of Crane Regulation Standards for Mobile
Offshore Drilling Units, Offshore Supply Vessels,
and Floating Outer Continental Shelf Facilities
(Docket Number: USCG–2011–0992).

expects these changes to have no direct
cost savings since they are inseverable
from the cost savings noted previously.
The compliance alternatives remove
overly prescriptive requirements,
simplify regulatory compliance, and
provide regulatory flexibility for
industry. In this rule, the Coast Guard
includes the compliance alternative to
hydrostatic tests from the proposed rule,
thereby allowing the regulated public to
perform an internal inspection in lieu of
the hydrostatic test. The inclusion of
this compliance alternative saves a
given vessel owner labor and material to
the extent that it is used. To comply
with the existing requirement for
hydrostatic tests, the vessel owner must
remove existing lagging around the unit,
then replace it once the test is
completed. The compliance alternative
involves less labor and does not
necessitate the removal and replacement
of lagging as the existing requirements
do. The Coast Guard has not estimated
a cost or cost savings for this alternative,
as it is unknown how many vessel
owners or operators will choose to
pursue the alternative. Because
equipment sizes vary, the amount of
labor and material needed to comply
now and under the alternative is also
unknown.16
The quantifiable cost savings from the
rule are due to a reduction in the
number of equivalency requests from
the regulated public, as well as time
dedicated to continuing education on
older standards. There are also
quantifiable cost savings for the Federal
Government because Coast Guard
personnel will no longer have to review
and approve equivalency requests from
the regulated public. Additionally,
Coast Guard employees will no longer
need to continue with education on
older, outdated standards.
To estimate the cost savings of the
final rule, the Coast Guard first
determined the wages of affected
workers. For Coast Guard military
personnel, using Commandant
Instruction W, we found the wage rate
for officers, who are engineers, at the O–
3 and O–4 rank, to be $89 and $105,
respectively. We also found an hourly
wage rate of $117 for a military
supervisory engineer with a rank of O–
5. The wage rates in Commandant
Instruction W are already loaded wage
rates; therefore, a load factor adjustment
is not required. For Coast Guard civilian
personnel, we used hourly pay rates
from OPM’s pay table for Federal
16 This information is needed to determine the
existing cost of compliance. Since it is unknown,
the Coast Guard is unable to estimate the cost
savings of the new compliance alternative.

Government workers in the Washington,
DC, locality pay area for calendar year
2022. The unloaded hourly wage rates
for a GS–14 (step 5) marine engineer
and a GS–15 (step 5) marine engineering
supervisor are $68.55 and $80.63,
respectively.
For private sector workers, we used
the hourly wage rates reported in the
BLS ‘‘Occupational Employment and
Wage Statistics’’ database for May 2022.
The unloaded mean hourly wage rate for
‘‘Marine Engineers and Naval
Architects’’ (occupational code 17–
2121) is $50.75. The unloaded mean
hourly rate for an ‘‘Architectural and
Engineering Manager’’ (occupational
code 11–9041) is $78.52.17
Next, the Coast Guard determined the
loaded mean hourly wage rates to
estimate the total cost savings of
employees more accurately by
accounting for employees’ non-wage
benefits. For Coast Guard civilian
positions, we used a Congressional
Budget Office (CBO) report ‘‘Comparing
the Compensation of Federal and
Private-Sector Employees, 2011 to
2015,’’ which includes information on
Federal Government worker average
wages and average total compensation.
We calculated a load factor by dividing
the average total compensation in Table
4 of the CBO report by the average
wages in Table 2 of the report for
Federal Government workers ‘‘All
Levels of Education.’’ We obtained a
load factor of about 1.69 ($64.80 ÷
$38.30).18
50083
We calculated the load factor (or
benefits multipliers) for the regulated
public with fourth quarter 2022 data
from the BLS’s ‘‘Employer Cost for
Employee Compensation’’ database
were used for the regulated public’s
wages.19 The Coast Guard determined
the load factor to be approximately 1.46,
rounded, for private sector employees
by dividing total compensation for
workers in ‘‘Transportation and Material
Moving’’ occupations by wages ($33.01
÷ $22.66 = 1.46). We estimated the load
factor for the applicable occupation
category by dividing the total
compensation by the unloaded hourly
wage rate. Table 5 displays the labor
categories, the source of the wage rates,
the total compensation, the wage rates,
and the calculated load factor.

After obtaining these load factors, the
Coast Guard estimated the cost savings
to employers under the final rule. The
Coast Guard assumed a constant wage
rate and a constant duration for tasks
throughout the period of analysis.20 We
based these estimates using 2022
dollars.
The Coast Guard multiplied the
unloaded wage rate for a ‘‘Marine
Engineer and Naval Architect’’
(occupational code 17–2121) of $50.75
by the load factor of 1.46 to obtain a
loaded mean hourly wage rate of about
$74.10 for this occupation. We also
multiplied the unloaded hourly rate for
an ‘‘Architectural and Engineering
Manager’’ (occupational code 11–9041)
of $78.52, which we then multiplied by
1.46 to obtain a loaded mean hourly
wage rate of about $114.64 for this
occupation.
For all provisions related to the
Federal Government, the Coast Guard
used publicly available data as found in
Commandant Instruction W and in the
OPM GS pay table to determine wage
rates for Coast Guard military and
civilian personnel, respectively. The
final rule has cost savings for Coast
Guard military and civilian engineers
and their supervisors at the MSC and in
CG–ENG. We estimated the labor rate
for a civilian GS–14 engineer in the
Coast Guard using a loaded mean hourly
wage rate of $115.85 (unloaded hourly
wage rate of $68.55 × 1.69 load factor).
We also estimated a loaded mean hourly
wage rate for a civilian GS–15
engineering supervisor in the Coast
Guard to be about $136.26 (unloaded
hourly wage rate of $80.63 × 1.69 load
factor). Military engineers at an O–3 or
O–4 rank will be equally involved in
processing equivalency requests and
staying educated on older standards.
Specifically, we expect that for each
equivalency request, either an O–3 or
O–4 military engineer spends 1 hour
reviewing and verifying the accuracy of
an equivalency request. We also expect
that six O–3 or O–4 military engineers
each spend roughly 30 minutes each
year on maintaining awareness of older
standards. Since engineers of each rank
are involved in these tasks, we used the
average wage rate of each one, which is
$97 (($89 + $105) ÷ 2).
According to Commandant
Instruction W, the loaded wage rate for
a military supervisory engineer is $117
for an O–5. Table 6 presents a summary
of the hourly wage rates we used in this
analysis.

As calculated by the average of the hourly wage rates of
O–3 and O–4 military engineers.
Appendix B to Commandant Instruction W (released August 2022).
The final rule results in cost savings
to the regulated public and the Coast
Guard from a reduction in the labor cost
for processing equivalency requests and
the removal of the education labor cost
for the older standards that are
incorporated by reference. An
equivalency is meant to provide an
opportunity for a vessel or facility
owner or operator to still meet a
regulatory requirement but allows them
to do so through a different arrangement
or piece of equipment. The Coast Guard
expects this final rule to generate cost
savings for owners or operators of
vessels or facilities who no longer need
to request an equivalency of subchapter
F regulatory standards from the MSC.
Generally, the reason an owner or
operator makes an equivalency request
is to seek a determination from the
Coast Guard as to whether an edition of
an industry standard not codified in the
CFR is sufficient for use.
Based on MSC and CG–5PS data, the
Coast Guard receives approximately 200
equivalency requests annually. The
Coast Guard estimates it takes a civilian
marine engineer or naval architect
employed by a vessel or facility owner
approximately 40 hours of time to
develop an equivalency request and
submit it to the Coast Guard for review.
An estimated 0.5 hours is needed for a
supervisor engineer to approve the
work. The owner or operator of a vessel
or facility asks for an equivalency
request from the Coast Guard by email.
Because a vessel or facility owner or
operator makes an equivalency request
by email, we did not estimate a cost for
this item.

In addition, the regulated public
realizes cost savings from the avoided
cost of education for maintaining
situational awareness on the existing
standards incorporated by reference,
which the rule eliminates. The Coast
Guard estimates that 0.5 hours are spent
annually by engineers on education
necessary to familiarize or re-familiarize
themselves with these standards. The
Coast Guard believes that, as industry
standards evolve and advance, older
editions may not be readily accessible,
even if they are incorporated by
reference into the CFR. As such, we
expect that engineers find the older
standards and read them on occasion to
maintain an awareness of how these
standards are different from current
industry standards.
Cost Savings to the Coast Guard
The Coast Guard also experiences cost
savings from the rule. When the Coast
Guard receives an equivalency request
from a vessel or facility owner or
operator, a Coast Guard engineering staff
member at the MSC must review the
request to provide a determination on
whether the standard(s) is equivalent to
the existing standard(s) found in
subchapter F. The Coast Guard MSC
engineer needs approximately 32 hours
to review an equivalency request,
followed by 0.5 hours of supervisor
review. In a small percentage of more
complex cases, the MSC works with
CG–5PS engineering staff to complete
the equivalency review. Following
review, the MSC emails a decision back
to the owner or operator. The Coast
Guard estimates it reviews 200
equivalency requests annually. To
calculate the costs avoided by Coast
PO 00000
Frm 00028
Fmt 4701
Sfmt 4700
Guard no longer processing equivalency
requests, we multiplied the number of
annual equivalency requests by the sum
of the duration of initial 1 hour of
military engineer review, 32 hours of
civilian engineer review, and 30
minutes of supervisory engineer review
multiplied by the loaded wage rates of
the respective Coast Guard personnel
performing the review (200 equivalency
requests × (1 hour × average wage rate
for military engineer + 32 hours × wage
rate for civilian engineer + 0.5 hours ×
wage rate for civilian engineering
supervisor)).
In addition, the Coast Guard will save
labor costs annually, because staff will
no longer need to maintain an
awareness of the older versions of
standards that are incorporated by
reference. The rule eliminates and
replaces them with newer standards.
The Coast Guard estimates that a marine
engineer with a vessel or facility owner
or manufacturer of vessels or vessel
components who is tasked with working
on equivalency requests spend 0.5 hours
annually on education on the older
standards. We similarly estimate that
Coast Guard personnel also spend 0.5
hours on education to maintain
awareness and knowledge of older
standards. This applies to six civilian
engineers and six military engineers
who work on equivalency requests. To
calculate the costs avoided by Coast
Guard personnel no longer requiring
education on outdated standards, we
multiplied 0.5 hours by the hourly wage
rates of the Coast Guard personnel (0.5
hours × (6 military engineers × average
wage rate for military engineer + 6
civilian engineers × wage rate for
civilian engineer)).

Cost Savings of the Rule
This rule will generate cost savings to
two segments of the regulated public:
vessel or facility owners or operators
and manufacturers. For vessel or facility
owners or operators, the Coast Guard
estimates that the annual undiscounted
cost savings from a reduced number of
equivalency requests is about $604,264
(200 equivalency requests × (40 hours ×
$74.10 loaded wage of a marine
engineer + 0.5 hours × $114.64 loaded
wage of an engineering manager)). The
annual undiscounted cost savings from
avoided education on outdated
standards is about $7,410 (200
equivalency requests × (0.5 hours ×
$74.10 loaded wage of a marine
engineer)). For manufacturers, we
estimate that the annual undiscounted
cost savings due to avoided education
on older standards is about $3,075 (83
manufacturers × (0.5 hours × $74.10
loaded wage of a marine engineer)).
Therefore, the total annual
undiscounted cost savings to the
regulated public is approximately
$614,749.
The Coast Guard estimates that the
total annual undiscounted cost savings
to the Federal Government due to
averted equivalency requests is
$774,466 (200 equivalency requests ×
((32 hours × $115.85 loaded wage of a
civilian engineer) + (1 hour × $97
loaded wage of a uniformed engineer) +
(0.5 hours × $136.26 loaded wage of a
50085
civilian engineering manager)). The
estimated total annual undiscounted
cost savings to the Federal Government
due to avoided education on outdated
standards is approximately $639 (0.5
hours × (6 civilian CG–5PS engineers ×
$115.85 loaded wage of a civilian
engineer) + (6 uniformed engineers ×
$97 loaded wage of a uniformed
engineer)). The total annual
undiscounted cost savings to the
Federal Government is approximately
$775,105.
The total undiscounted cost savings
from the rule, therefore, is
approximately $1,389,854. Table 7

Unquantified Benefits
In this final rule, the Coast Guard is
incorporating by reference updated
industry standards. These updated
standards reflect the latest available
technologies, practices, and procedures
that voluntary consensus standards
organizations, ship classification
societies, or maritime organizations
recommend for use within the industry.
The Coast Guard is making these
updates to harmonize the standards in
the CFR with the latest industry
standards. As a result, these updates
provide the qualitative benefit of greater
VerDate Sep<11>2014
18:22 Jun 11, 2024
Jkt 262001
consistency between the CFR and
current industry practices. Updating to
some newer editions of standards also
provides more flexibility for regulatory
compliance. In addition, the final rule
provides qualitative benefits through
certain editorial changes that correct for
inadvertent errors, remove obsolete
language, update Coast Guard contact
information, standardize the use of
words and phrases in the CFR, account
for relocation of certain provisions, and
standardize the designation of tables
and figures. These changes improve
clarity of regulatory requirements and
reduce confusion, thereby improving
PO 00000
Frm 00030
Fmt 4701
Sfmt 4700
service to the regulated public through
more accurate information.
Alternatives Considered
Within the Coast Guard’s
development of this rule, significant
alternatives to the regulatory
component(s) were considered to
determine if any alternative could
accomplish the stated objectives of
applicable statutes and could minimize
any significant economic impact of the
rule on small entities beyond the rule.
Among these alternatives were the
following:
E:\FR\FM\12JNR2.SGM
12JNR2
Federal Register / Vol. 89, No. 114 / Wednesday, June 12, 2024 / Rules and Regulations
Alternative 1: Take No Action
The Coast Guard could have chosen
not to pursue the rulemaking. Taking no
action would cause no incremental costs
to regulated entities nor to the Coast
Guard. However, in doing nothing, the
Coast Guard would have no mechanism
to update regulations to reflect current
practices and improve their relevance to
the public. There would be neither an
increase nor decrease in benefits to
regulated entities due to the alternative.
The rule has been estimated to produce
quantifiable cost savings to the Coast
Guard and the regulated public, which
would not be possible under the
alternative of no action.
In addition, the standards currently
incorporated by reference are outdated.
To keep them codified would, in theory,
maintain existing safety levels.
However, because they are so outdated,
they are sparsely available. Compliance
with them may become problematic in
the future due to lack of availability.
The older editions of the standards do
not contain guidance for several current
industry practices. Maintaining the
regulations with the existing standards
incorporated by reference does not
allow for the cost savings the rule does.
We rejected this alternative because
taking no action would not provide
additional benefits to the public. The
public and the Coast Guard, under this
alternative, would not experience cost
savings through reduction in the
number of submissions of equivalency
requests and ongoing education on
outdated standards. Additionally,
reliance on older editions of standards
in the CFR as industry practices
continue to evolve may cause confusion.
By rejecting this alternative, the Coast
Guard will provide greater clarity of
regulatory requirements and better
service to public with the final rule.
ddrumheller on DSK120RN23PROD with RULES2
Alternative 2: Delay the Effective Date
The Coast Guard could have delayed
the effective date beyond the 90 days
after publication of the final rule
currently provided. Delayed effective
dates are used to aid in compliance
implementation, particularly when the
labor costs or capital costs are
considerable. The compliance costs for
this rule are, as noted earlier, zero, and
a delayed effective date delays the cost
savings opportunities to all parties. For
these reasons, the Coast Guard rejected
this alternative.
Alternative 3: Exempt Small Entities
The Coast Guard could have
exempted small entities from some or
all of the rule’s provisions. In principle,
an exemption could save small entities
VerDate Sep<11>2014
18:22 Jun 11, 2024
Jkt 262001
time and money to comply with
regulations. Exemptions for small
entities often are used when costs of
compliance, such as capital costs, are
high. However, there are no costs of
compliance for this rule. For this
alternative, an exemption may cause the
cost savings opportunities of the
rulemaking to be precluded for small
entities and, thereby, the total value of
the rule’s cost savings declines
accordingly.
The rule implements requirements for
business practices in which the majority
(if not all) of small businesses now
engage. An exemption for small
business entities from the rulemaking
would have little effective and practical
impact on small business entities. There
is a high level of voluntary compliance
and limited applicability for the affected
population. The costs of compliance are
zero and the rule is applicable only if an
actionable event occurs (for example, if
a new vessel is procured or an existing
vessel undergoes a major conversion).
For these reasons, the Coast Guard did
not pursue an exemption for small
entities.
B. Small Entities
Under the Regulatory Flexibility Act
of 1980 (5 U.S.C. 601–612), we have
considered whether this final rule will
have a significant economic impact on
a substantial number of small entities.
The term ‘‘small entities’’ comprises
small businesses, not-for-profit
organizations that are independently
owned and operated and are not
dominant in their fields, and
governmental jurisdictions with
populations of less than 50,000.
The rule creates cost savings for
industry because we estimate fewer
equivalency requests will be submitted
to the Coast Guard. We expect
equivalency requests to be submitted by
owners or operators of new U.S.-flagged
vessels or facilities who may have
questions about standards that are not in
46 CFR subchapter F. Over a 6-year
period, from 2016–2021, we found 771
new U.S.-flagged vessels entered
service, or an average of about 129
annually during this period. We found
that 156 companies owned the 771
vessels. The final rule also potentially
affects 22 nonprofits, under the
conditions specified in the rule.
Using the publicly-available online
database ‘‘ReferenceUSAgov’’ (in
addition to individual online searches
of companies) to search for companyspecific information, such as annual
revenues and number of employees, we
found revenue and employee
information on 139 of the 178
PO 00000
Frm 00031
Fmt 4701
Sfmt 4700
50087
companies and nonprofits,26 or
approximately 78 percent.27 Using the
Small Business Administration’s (SBA)
‘‘Table of Size Standards’’ 28 and the
North American Industry Classification
System (NAICS) codes listed in the
table, we found 49 of the 139 companies
to be small entities. We found the other
90 companies to be not small. We did
not find information on the remaining
38 companies and one nonprofit;
therefore, we assumed these companies
to be small entities for a total of 88 small
entities out of 178, or approximately 49
percent.
We analyzed the potential economic
impacts of this final rule on small entity
companies and nonprofits and found
that each entity that no longer submits
an equivalency request saves
approximately $3,058 ((40 hours ×
$74.10 loaded wage of a marine
engineer or equivalent employee) + (0.5
hours × $114.64 loaded wage rate of an
engineering manager or equivalent
employee) + (0.5 hours × $74.10 loaded
wage of a marine engineer or equivalent
employee)) annually. The cost savings
of $3,058 is less than 1 percent of
annual revenue for 42 out of 47 small
entity companies and nonprofits for
which we obtained revenue
information, or approximately 89
percent.29 We found cost savings to
revenue ratios of greater than 1 percent
but less than 2 percent for the five
remaining small entity companies and
non-profits.30
Additionally, the final rule potentially
impacts manufacturers of vessels or
vessel or facility components. We
estimate the average potential cost
savings to manufacturers for no longer
needing education older standards is
about $57 ($114.64 loaded hourly wage
of an engineering manager × 0.5 hours).
Therefore, the Coast Guard certifies
under 5 U.S.C. 605(b) that this final rule
26 Including colleges and universities, museums,
and science foundations.

of the SBA’s table of size standards. Readers can

29 The Coast Guard found revenue data on a 48th
small entity, however, the reported revenue was $0,
which we believe may have been in error. Since we
could not verify the accuracy of this reported
amount, we chose not to include this data point in
our assessment of the potential economic impacts
of the rule on small entities.
30 For four small entity companies and one small
entity nonprofit, the impact from a reduced number
of equivalency requests would be greater than 1
percent and less than 2 percent of annual revenues.

Federal Register / Vol. 89, No. 114 / Wednesday, June 12, 2024 / Rules and Regulations
does not have a significant economic
impact on a substantial number of small
entities because the cost savings of this
final rule will have a positive impact on
revenues of less than 1 percent on
nearly 90 percent of the small entity
owners that we researched. We also
found that the potential cost savings to
manufacturers is less than 1 percent of
revenue among all manufacturers for
which we could obtain revenue
information. Furthermore, no small
entity that does not submit an
equivalency request will be impacted by
any cost savings.

organization, or governmental
jurisdiction qualifies as a small entity
and that this rule will have a significant
economic impact on it, please submit a

ADDRESSES section. In your comment,
explain why you think it qualifies and
how and to what degree this rule will
affect it economically.

C. Assistance for Small Entities
Under section 213(a) of the Small
Business Regulatory Enforcement
Fairness Act of 1996, Public Law 104–
121, we want to assist small entities in
understanding this rule so that they can
better evaluate its effects on them and
participate in the rulemaking. If the rule
affects your small business,
organization, or governmental
jurisdiction and you have questions
concerning its provisions or options for
compliance, please call or email the
person in the FOR FURTHER INFORMATION
CONTACT section of this rule. The Coast
Guard will not retaliate against small
entities that question or complain about
this rule or any policy or action of the
Coast Guard.
Small businesses may send comments
on the actions of Federal employees
who enforce, or otherwise determine
compliance with, Federal regulations to
the Small Business and Agriculture
Regulatory Enforcement Ombudsman
and the Regional Small Business
Regulatory Fairness Boards. The
Ombudsman evaluates these actions
annually and rates each agency’s
responsiveness to small business. If you
wish to comment on actions by
employees of the Coast Guard, call 1–
888–REG–FAIR (1–888–734–3247).
D. Collection of Information
The Paperwork Reduction Act of 1995
(44 U.S.C. 3501–3520) requires the U.S.
Coast Guard to consider the impact of
paperwork and other information
collection burdens imposed on the
public. As defined in 5 CFR 1320.3(c),
‘‘collection of information’’ comprises
reporting, recordkeeping, monitoring,
VerDate Sep<11>2014
18:22 Jun 11, 2024
Jkt 262001
posting, labeling, and other similar
actions.
This rule does not require a
modification of an existing collection of
information and does not call for new
collection of information under the
Paperwork Reduction Act.
E. Federalism
A rule has implications for federalism
under Executive Order 13132
(Federalism) if it has a substantial direct
effect on the States, on the relationship
between the national Government and
the States, or on the distribution of
power and responsibilities among the
various levels of Government. We have
analyzed this rule under Executive
Order 13132 and determined that it is
consistent with the fundamental
federalism principles and preemption
requirements described in Executive
Order 13132. Our analysis follows.
It is well settled that States may not
regulate in categories reserved by
Congress for regulation by the Coast
Guard. It is also well settled that all of
the categories regulated under 43 U.S.C.
1333 and 46 U.S.C. 3306 and 3703, as
well as any other category in which
Congress intended the Coast Guard to be
the sole source of a vessel’s obligations,
are within the field foreclosed from
regulation by the States. See United
States v. Locke and Intertanko v. Locke,
529 U.S. 89 (2000). This rulemaking
updates the references to incorporated
standards in 46 CFR subchapter F,
which is authorized under 43 U.S.C.
1333, 46 U.S.C. 3306, and 46 U.S.C.
3703. Therefore, because the States may
not regulate within these categories, this
rule is consistent with the fundamental
federalism principles and preemption
requirements described in Executive
Order 13132.
While it is well settled that States may
not regulate in categories in which
Congress intended the Coast Guard to be
the sole source of a vessel’s obligations,
the Coast Guard recognizes the key role
that State and local governments may
have in making regulatory
determinations. Additionally, for rules
with federalism implications and
preemptive effect, Executive Order
13132 specifically directs agencies to
consult with State and local
Governments during the rulemaking
process. If you believe this rule has
implications for federalism under
Executive Order 13132, please contact
the person listed in the FOR FURTHER
INFORMATION section of this preamble.
F. Unfunded Mandates Reform Act
The Unfunded Mandates Reform Act
of 1995, 2 U.S.C. 1531–1538, requires
Federal agencies to assess the effects of
PO 00000
Frm 00032
Fmt 4701
Sfmt 4700
their discretionary regulatory actions. In
particular, the Act addresses actions
that may result in the expenditure by a
State, local, or tribal government, in the
aggregate, or by the private sector of
$100,000,000 (adjusted for inflation) or
more in any one year. Although this rule
does not result in such an expenditure,
we do discuss the effects of this rule
elsewhere in this preamble.
G. Taking of Private Property
This rule does not cause a taking of
private property or otherwise have
taking implications under Executive
Order 12630 (Governmental Actions and
Interference with Constitutionally
Protected Property Rights).
H. Civil Justice Reform
This rule meets applicable standards
in sections 3(a) and 3(b)(2) of Executive
Order 12988, (Civil Justice Reform), to
minimize litigation, eliminate
ambiguity, and reduce burden.
I. Protection of Children
We have analyzed this rule under
Executive Order 13045 (Protection of
Children from Environmental Health
Risks and Safety Risks). This rule is not
an economically significant rule and
does not create an environmental risk to
health or risk to safety that might
disproportionately affect children.
J. Indian Tribal Governments
This rule does not have Tribal
implications under Executive Order
13175 (Consultation and Coordination
with Indian Tribal Governments),
because it does not have a substantial
direct effect on one or more Tribal
governments, on the relationship
between the Federal Government and
Tribal governments, or on the
distribution of power and
responsibilities between the Federal
Government and Tribal governments.
K. Energy Effects
We have analyzed this rule under
Executive Order 13211 (Actions
Concerning Regulations That
Significantly Affect Energy Supply,
Distribution, or Use). We have
determined that it is not a ‘‘significant
energy action’’ under that order because
it is not a ‘‘significant regulatory action’’
under Executive Order 12866 and is not
likely to have a significant adverse effect
on the supply, distribution, or use of
energy.
L. Technical Standards
The National Technology Transfer
and Advancement Act, codified as a
note to 15 U.S.C. 272, directs agencies
to use voluntary consensus standards in
E:\FR\FM\12JNR2.SGM
12JNR2
ddrumheller on DSK120RN23PROD with RULES2
Federal Register / Vol. 89, No. 114 / Wednesday, June 12, 2024 / Rules and Regulations
their regulatory activities unless the
agency provides Congress, through
OMB, with an explanation of why using
these standards would be inconsistent
with applicable law or otherwise
impractical. Voluntary consensus
standards are technical standards (such
as specifications for materials,
performance, design, or operation; test
methods; sampling procedures; and
related management systems practices)
that are developed or adopted by
voluntary consensus standards bodies.

(4) Internally fired firetube boiler
(scotch boiler). An internally fired
firetube boiler is a steam boiler
containing furnaces, one or more
combustion chambers and tubes or
flues, which are surrounded by water
and through which the products of
combustion pass from the furnace to the
uptake.
(5) Externally fired firetube or flue
boiler (horizontal return tubular). An
externally fired firetube or flue boiler is
a steam boiler, part of the outer shell of
which is exposed to fire or to the
products of combustion, and containing
flues through which such products pass
from the furnace to the uptake.
(6) Unfired steam boiler. A pressure
vessel in which steam is generated by
means other than fuel combustion is
classed as an unfired steam boiler. (See
§ 54.01–10 of this subchapter.)
(b) Parts of boilers—(1) Superheater.
A superheater is an appliance, normally
consisting of tube rows, for the purpose
of increasing the temperature of steam
above the saturation temperature.
(2) Economizer. An economizer is a
feed-water heater usually located in the
uptake or casing of a boiler to absorb
heat from the waste gases.
(3) Furnace. A furnace is a firebox or
a large flue in which the fuel is burned.
(4) Flues. Flues are cylindrical shells
made of seamless or welded tubing, or
with a riveted longitudinal joint, the
ends being attached by riveting or
welding. Their purpose is to provide
additional heating surface and to form a
path for the products of combustion.
(5) Tubes. Tubes are cylindrical shells
of comparatively small diameter
constituting the main part of the heating
surface of a boiler or superheater.
(c) Pressure relief devices. For boilers,
pressure vessels, and pressure piping, a

superheater, the drum safety valve must
be set at a pressure not less than that of
the superheater safety valve setting plus
5 pounds, plus the pressure drop
through the superheater and associated
piping, including the desuperheater if
fitted. See also § 52.01–95(b)(1).
(3) Drum pilot actuated superheater
safety valves are permitted provided the
setting of the pilot valve and
superheater safety valve is such that the
superheater safety valve will open
before the drum safety valve.

and superheater safety valves of all
boilers.
(3) The safety valve body drains
required by PG–71 of Section I of the
ASME BPVC must be run as directly as
possible from the body of each safety
valve, or the drain from each safety
valve may be led to an independent
header common only to boiler safety
valve drains. No valves of any type may
be installed in the leakoff from drains or
drain headers and they must be led to
suitable locations to avoid hazard to
personnel.
(d)(1) (Modifies PG–72.) The

qualification and production toughness
tests) are contained in subpart 54.05.
(c) Materials suitable for a given
minimum service temperature may be
used in warmer service. Steels differing
in chemical composition, mechanical
properties, or heat treatments from those
specified may be specially approved by
the Commandant. Similarly, aluminum
alloys and other nonferrous materials
not intended to be covered by these

Toughness test specimens.
(a) Charpy V-notch impact tests.
Where required, Charpy V-notch tests
must be conducted in accordance with
ASTM E23 (incorporated by reference,
see § 54.01–1), using the Type A
specimen shown in ASTM E23—Figure
4. Special attention is drawn to the fact
that the Charpy Keyhole and U-notch
specimens are not acceptable substitutes
for the Charpy V-notch specimen and
must not be used to qualify materials
within the scope of this subpart. Each
set of Charpy impact tests must consist
of three specimens. For materials 1⁄2inch thick or less, the largest possible
Charpy specimens for that thickness
must be cut centered at the material’s
mid-thickness. For materials thicker
than 1⁄2-inch, full size Charpy specimens
must be cut centered at a location as
near as practicable to a point midway
between the material’s surface and halfthickness. Except where otherwise
specified, transversely oriented
specimens must be used. When
longitudinal specimens are used, the
required energy values may not be less
than 1.5 times the values required for
transversely oriented specimens. In all
cases, the notch must be cut normal to
the material’s surface. Test specimens
must be taken at least one ‘‘t’’ from any
heat-treated edge (where ‘‘t’’ is the
material’s nominal thickness).
(b) Drop weight tests. Where required,
drop weight tests must be conducted for
no-break performance in accordance
with ASTM E208 (incorporated by
reference, see § 54.01–1). For material
thicknesses between 1⁄2-inch and 5⁄8inch, the ASTM E208 specimen P–3,
machined to 1⁄2-inch thickness, must be
used with a stop distance of 0.090-inch.

In preparing weld specimens for drop
weight testing, weld reinforcement must
be ground flush, the hard facing bead
centered on and transverse to the weld,
and the notch centered on and parallel
to the weld axis.
(c) Retest procedures. (1) When
Charpy V-notch impact specimens are
used and the average value of the three
initial specimens fails to meet the stated
requirements by an amount not
exceeding 15 percent, or the value for
more than one specimen is below the
required average value of when the
value for one specimen is below the
minimum value permitted for a single
specimen by an amount not exceeding
15 percent, three additional specimens
from the same material may be tested
and the results combined with those
previously obtained to form a new
average. This new average of six
specimens must exceed the specified
minimum average. In the event the
Charpy retests fail, the material may still
be qualified by exhibiting a no-break
performance when tested in accordance
with the drop weight procedure, if
applicable. Two drop weight specimens
must be tested for each Charpy V-notch
set of three initial specimens which
failed to qualify. Failure of either or
both of these drop weight specimens
will constitute rejection of the material
or weldments represented, except as
outlined in paragraph (c)(3) of this
section.
(2) When drop weight specimens are
used, retests are permitted only within
the limits prescribed in ASTM E208,
except as outlined in paragraph (c)(3) of
this section.
(3) If, for heat treated base material,
the required toughness results are not
obtained in the initial test or in the
retest, the material may be reheat treated
one time and tested again in accordance
with the initial requirements for the
material.
(d) Alternate toughness tests. The
Charpy V-notch impact values of
§§ 54.05–20(a) and 54.05–25(a) are
representative of those which correlate
with the nil-ductility transition
temperature determined by the dropweight tests for the steels specified in
§ 54.25–10. For materials for which
there are other data showing suitable
correlation between Charpy V-notch and
drop-weight tests, V-notch acceptance
limits different from those tabulated
herein may be specially approved by the
Commandant, based upon the actual
correlation. In the case of steels for
which the tabulated Charpy V-notch
values can be shown to be inapplicable

acceptance may be based upon the
material exhibiting a no-break
performance when tested in accordance
with the drop-weight procedure.
Whenever the drop-weight test is used
as an alternative to the Charpy V-notch
test, two drop-weight specimens must
be tested for each set of three Charpy Vnotch specimens otherwise required. If
the drop-weight test cannot be
performed because of material thickness
limitations (less than one-half inch) or
product shape, or is otherwise
inapplicable (because of heat treatment,
chemistry, etc.), other tests and/or test
criteria will be specified by the
Commandant to assure the adequacy of
the material for the intended
application.
§ 54.05–6
Toughness test temperatures.
Each toughness test must be
conducted at temperatures not warmer
than ¥20 °F or 10 °F below the
minimum service temperature,
whichever is lower, except that for
service at or below ¥320 °F, the tests
may be conducted at the service
temperature in accordance with § 54.25–
10(a)(2).
§ 54.05–10 Certification of material
toughness tests.
(a) Plate material. The manufacturer
of plates may certify such material,
provided it has been given an
appropriate heat-treatment, by reporting
the results of tests of one set of Charpy
impact specimens or of two drop weight
specimens, as applicable, taken from
each plate as rolled. Impact specimens
must be taken as outlined in section 12
of ASTM A20/A20M (incorporated by
reference, see § 54.01–1). The long axis
of the Charpy specimen must be
perpendicular to the final direction of
rolling. When the direction of maximum
stress is unknown, the manufacturer
may certify on the basis of specimens
taken parallel to the final direction of
rolling.
(b) Pipe or tube material. (1) The
manufacturer of pipe, tube, or welded
fittings formed from pipe or tube may
certify such material by reporting the
results of tests of one set of Charpy
impact specimens, provided the
requirement for production in this
paragraph (b)(1) or (2) of this section, as
well as the requirement for sampling in
paragraph (b)(3) of this section are met.
The specimens must have the major axis
parallel to the length of pipe or tube. In
the case of welding fittings, the
specimens may be taken from the tubing
prior to forming provided the fittings are
normalized after forming. Such
specimens must be normalized before
testing.

equipped with recording pyrometer
provided all have been produced from
a single melting furnace heat and are
subsequently processed in the same
manner. If more than one melting
furnace heat is present in the batch heattreating furnace, means of identification
must be provided and one set of
specimens must be taken from each
heat.
(4) One set of impact specimens must
be taken from one pipe or tube picked
at random from each heat or furnace
batch or portion thereof to be certified.
(c) Forgings and forged or rolled
fittings. (1) The manufacturer of forgings

drop-weight specimens, as applicable,
taken from each 5 short tons of product
from each melting heat provided the
requirements in this paragraph for
production and sampling are met.
(2) One or more test blocks must be
cut from billets or blooms selected at
random from each heat of material. Each
test block must be forge-reduced in
thickness to the thickness of the
finished forgings to be certified, within
the limitations set below. After forging
to the reduced thickness, the test block
must be heat-treated in the same manner
as the finished forgings represented,
which heat-treatment of test blocks may
be carried out in the furnace with the
forgings, or separately. If carried out
separately, both heat-treatments must be
done in automatically controlled
furnaces equipped with calibrated
recording pyrometers, the certified
records of which must be made
available to the inspector.
(3) One set of Charpy impact
specimens or two drop-weight
specimens, as applicable, must be cut
from each such test block and these
specimens will represent all forgings
(up to 5 short tons) that are from the
same heat of material and given the
same heat-treatment as the test block,

differ from that of the test block by more
than plus or minus 50 percent of 11⁄2
inches, whichever is less, except that
forged flanges and tube sheets thicker
than 51⁄2 inches may be qualified from
a 4-inch test block.
(4) As many test blocks must be made
as are required under the foregoing rule
in paragraph (c)(3) of this section to
cover the weight of product and range
of thickness found in the forgings
represented. The major axis of the test
specimens must be parallel to the length
of the test block.
(d) Bars and shapes, rolled or forged.
(1) The manufacturer of forged or rolled
bars and shapes may certify such by
reporting the results of one set of
Charpy impact specimens, or two dropweight specimens, as applicable,
produced from each 5 short tons from a
single melting furnace heat, processed
in a similar manner and heat-treated as
a single furnace batch, if heat-treated.
The impact specimens must be cut from
the heaviest section, clear of fillets, of
the shape being tested with the axis of
the specimens parallel to the axis of the
bar or shape.

from the same heat of material and that
have a thickness that does not differ
from the thickness of the section from
which the specimens were taken by
more than plus or minus 25 percent, or
1.5 inches, whichever is less. A wider
range of thicknesses from one heat may
be covered by taking additional sets of
specimens from thicker or thinner
material as may be required.
(3) The test specimens must be heattreated in the same manner as the
castings represented, which heattreatment of specimens may be carried
out in the furnace with the castings
represented, or separately, but if carried
out separately both heat-treatments
must be done in automatically
controlled furnaces equipped with
calibrated recording pyrometers, the
certified records of which must be made
available to the marine inspector.
(f) Small parts. The manufacturer of
small parts, either cast or forged, may
certify a lot of not more than 20
duplicate parts or 5 short tons,
whichever is less, by reporting the
results of one set of Charpy impact
specimens, or two drop-weight
specimens, as applicable, taken from
one such part selected at random,

impact test, the Commandant will
determine toughness qualifications
based on material, chemical, and
mechanical properties.
§ 54.05–15 Weldment toughness tests—
procedure qualifications.
(a) Plate for which Charpy V-notch
impact testing is required in the parent
material and for which V-notch minima
are specified must similarly have
welding procedures qualified for
toughness by Charpy V-notch testing.
For these tests, the test plates must be
oriented with their final rolling
direction parallel to the weld axis (i.e.,
so that transverse impact specimens
result), and with the V-notch normal to
the plate surface. The sample weld joint
preparation must be the same as that
used in production. The number of test
specimens and the location of their
notches must be as shown in Figure 1
to § 54.05–15(a) and as described in
paragraphs (a)(1) through (5) of this
section.
(1) Three specimens with the notch
centered in the weld metal.
(2) Three specimens with the notch
centered on the fusion line between
parent plate and weld. (The fusion line
may be identified by etching the
specimen with a mild reagent.)
(3) Three specimens with the notch
centered in the heat affected zone, 1 mm
from the fusion line.
(4) Same as paragraph (a)(3) of this
section, but 3 mm from the fusion line.
(5) Same as paragraph (a)(3) of this

for which a Charpy V-notch correlation
with NDT is not known, and which are
themselves tested for toughness by the
drop-weight procedure, must have
welding procedures similarly qualified

§ 54.05–16
Production toughness testing.
(a) For vessels of welded construction,
production toughness test plates must
be prepared for each 50 feet of
longitudinal and circumferential buttweld in each Class I–L vessel, or for
each 150 feet in each Class II–L vessel,
except for material other than stainless
steel that is exempted from impact test
requirements by this subchapter. In the
case of stainless steels, weld production
toughness tests may be limited to weld
metal only if this is all that is required
be § 54.25–15. The test-plate thickness
must be the same as that of the vessel
wall at the location of the production
weld being sampled. The test plates
must be prepared, wherever possible, as
run-off tabs attached at the ends of weld
butts or seams. The rolling direction of
the run-off tabs should be oriented
parallel to the rolling direction of the
adjacent production material. The testplate material must be taken from one
of the heats of material used in the
vessel, and both the electrodes and
welding procedures must be the same as
used in the fabrication of the vessel.
From each test plate, one set of three
Charpy impact bars or two drop-weight
specimens, as applicable according to
the test used in procedure qualification,
must be taken transverse to the weld
axis. For Charpy V-notch specimens, the
notch must be normal to the material
surface and its location alternated
(approximately) on successive tests
between the weld metal and heat
affected zone. Thus, approximately half
of all weld production impact tests will
be of weld metal and half of heat
affected zone material. For the weld
metal tests, the V-notch is to be centered
between the fusion lines. For the heat
affected zone tests, the notch is to be
centered so as to sample, as nearly as
practicable, the most critical location for
toughness observed in the weld
procedure qualification tests. Where the
drop weight specimen is used in
production weld testing, it must be
prepared in the same manner as
specified for procedure qualification
testing in § 54.05–15(b).
(b) For vessels not exceeding 5 cubic
feet in volume, one set of impact
specimens, or two drop-weight
specimens, as applicable according to
the test used in procedure qualification,
may represent all vessels from the same
heat of material not in excess of 100
vessels, or one heat-treatment furnace
batch. In addition, when such vessels
are welded, one weld test plate made
from one of the heats of material used,
and two sets of impact specimens or two
drop-weight specimens, as applicable,
cut therefrom, may represent the weld
metal in the smallest of: One lot of 100
vessels or less; or each heat-treatment
furnace batch; or each 50 feet of welding
for Class I–L vessels; or each 150 feet of
welding for Class II–L vessels.
(c) For several vessels or parts of
vessels being welded in succession, the
plate thickness of which does not vary
by more than one-fourth inch, and
which are made of the same grade of
material, a test plate must be furnished
for each 50 feet of welding for Class I–
L vessels or 150 feet of welding for Class
II–L vessels. For each 50- or 150-foot
increment of weld, as applicable, the
test plates must be prepared at the time
of fabrication of the first vessel
involving that increment.
(d) The test plates and any other test
material from which toughness test
specimens are cut must be given the
same heat-treatment as the production
material they represent. Test specimens
representing other material than the
weld toughness test plates should
preferably be cut from a part of the
vessel material but may be cut from like
50113
material that has been heat-treated
within the temperature range specified
by the producer in treating the actual
vessel material.
(e) For nonpressure vessel type tanks
and associated secondary barriers, as
defined in § 38.05–4, subchapter D of
this chapter, production toughness test
plates must be prepared in accordance
with paragraphs (a) and (d) of this
section. One set of toughness test plates
must be prepared for each 165 feet (50
meters) of production butt-type welds.
§ 54.05–17 Weld toughness test
acceptance criteria.
(a) For Charpy V-notch impact tests
the energy absorbed in both the weld
metal and heat affected zone impact
tests in weld qualification and
production must be:
(1) For weld metal specimens, not less
than the transverse values required for
the parent material.
(2) For heat affected zone specimens,
when the specimens are transversely
oriented, not less than the transverse
values required for the parent material.
(3) For heat affected zone specimens,
when the specimens are longitudinally
oriented, not less than 1.5 times the
transverse values required for the parent
material.
(b) For drop-weight tests both
specimens from each required set must
exhibit a no-break performance.
§ 54.05–20 Impact test properties for
service of 0 ≥F and below.
(a) The impact energies of each set of
transverse Charpy specimens may not
be less than the values shown in table
1 to § 54.05–20(a). Only one specimen
in a set may be below the required
average and the value of that specimen
must be above the minimum impact
value permitted on one specimen only.
See § 54.05–5(c) for retest requirements.

§ 54.10–10 Standard hydrostatic test
(modifies UG–99).
§ 54.10–15
100).
(a) All pressure vessels must
satisfactorily pass the hydrostatic test
prescribed by this section, except those
pressure vessels noted under § 54.10–
15(a).
(b) The hydrostatic-test pressure must
be at least one and three-tenths (1.30)
times the maximum allowable working
pressure stamped on the pressure
vessel, multiplied by the ratio of the
stress value ‘‘S’’ at the test temperature
to the stress value ‘‘S’’ at the design
temperature for the materials of which
the pressure vessel is constructed. The
values for ‘‘S’’ must be taken from tables
UCS 23, UNF 23, UHA 23, or UHT 23
of Section VIII of the ASME BPVC
(incorporated by reference, see § 54.01–
1). The value of ‘‘S’’ at test temperature
must be that taken for the material of the
tabulated value of temperature closest to
the test temperature. The value of ‘‘S’’
at design temperature must be as
interpolated from the appropriate table.
No ratio less than one must be used. The
stress resulting from the hydrostatic test
must not exceed 90 percent of the yield
stress of the material at the test
temperature. External loadings, which
will exist in supporting structure during
the hydrostatic test, should be
considered. The design must consider
the combined stress during hydrostatic
testing due to pressure and the support
reactions. This stress must not exceed
90 percent of the yield stress of the
material at the test temperature. In
addition, the adequacy of the supporting
structure during hydrostatic testing
should be considered in the design.
(c) The hydrostatic test pressure must
be applied for a sufficient period of time
to permit a thorough examination of all
joints and connections. The test must
not be conducted until the vessel and
liquid are at approximately the same
temperature.
(d) Defects detected during the
hydrostatic test or subsequent
examination must be completely
removed and then inspected. Provided
the marine inspector gives their
approval, they may then be repaired.
(e) Vessels requiring stress relieving
must be stress relieved after any
welding repairs have been made. (See
UW–40 of Section VIII of the ASME
BPVC.)
(f) After repairs have been made the
vessel must again be tested in the
regular way, and if it passes the test, the
marine inspector may accept it. If it
does not pass the test, the marine
inspector can order supplementary
repairs, or, if in their judgment the
vessel is not suitable for service, they
may permanently reject it.
(a) Pneumatic testing of welded
pressure vessels is permitted only for
those units which are so designed and
supported that they cannot be safely
filled with water, or for those units
which cannot be dried and are to be
used in a service where traces of the
testing medium cannot be tolerated.
(b) Proposals to pneumatically test
must be submitted to the cognizant
Officer in Charge, Marine Inspection, for
approval.
(c) Except for enameled vessels, for
which the pneumatic test pressure must
be at least equal to, but need not exceed,
the maximum allowable working
pressure to be marked on the vessel, the
pneumatic test pressure must be at least
equal to one and one-tenth (1.10) times
the maximum allowable working
pressure to be stamped on the vessel
multiplied by the lowest ratio (for the
materials of which the vessel is
constructed) of the stress value ‘‘S’’ for
the test temperature of the vessel to the
stress value ‘‘S’’ for the design
temperature (see UG–21 of Section VIII
of the ASME BPVC (incorporated by
reference; see § 54.01–1)). In no case
must the pneumatic test pressure exceed
one and one-tenth (1.10) times the basis
for calculated test pressure as defined in
UA–60(e) of Section VIII of the ASME
BPVC.
(d) The pneumatic test of pressure
vessels must be accomplished as
follows:
(1) The pressure on the vessel must be
gradually increased to not more than
half the test pressure.
(2) The pressure will then be
increased at steps of approximately onetenth the test pressure until the test
pressure has been reached.
(3) The pressure will then be reduced
to the maximum allowable working
pressure of the vessel to permit
examination.
(e) Pressure vessels pneumatically
tested must also be leak tested. The test
must be capable of detecting leakage
consistent with the design requirements
of the pressure vessel. Details of the leak
test shall be submitted to the
Commandant for approval.
(f) After satisfactory completion of the
pneumatic pressure test, the vessel may
be stamped in accordance with § 54.10–
20. A marine inspector must observe the
pressure vessel in a loaded condition at
the first opportunity following the
pneumatic test. The tank supports and
saddles, connecting piping, and
insulation if provided must be
examined to determine if they are
satisfactory and that no leaks are
evident.

§ 54.10–20
Marking and stamping.
(a) Pressure vessels (Replaces UG–
116, except paragraph (k), and UG–118).
Pressure vessels that are required by
§ 54.10–3 to be stamped with the Coast
Guard Symbol must also be stamped
with the following information:
(1) Manufacturer’s name and serial
number.
(2) Coast Guard number, see § 50.10–
30 of this subchapter (only applicable to
pressure vessels inspected as required
by § 54.10–3(b)).
(3) Coast Guard Symbol, which is
affixed only by the marine inspector.

(b) Multichambered pressure vessels
(Replaces UG–116(k)). In cases where
more than one pressure vessel is
involved in an integral construction, as
with a heat exchanger, the manufacturer
may elect to class the component
pressure vessels differently. In such
cases they must stamp the combined
structures as required in paragraph (a) of
this section with information for each
pressure vessel. Where an item for
stamping is identical for both vessels, as
with name and address of manufacturer,
it need not be duplicated. However,
where differences exist, each value and
the vessel to which it applies shall be
clearly indicated.
(c) Stamping data (Replaces UG–117).
Except as noted in paragraph (d) of this
section, the data must be stamped
directly on the pressure vessel. The data
must be legibly stamped and must not
be obliterated during the service life of
the pressure vessel. In the event that the
portion of the pressure vessel upon
which the data is stamped is to be
insulated or otherwise covered, the data
must be reproduced on a metal
nameplate. This plate must be securely
attached to the pressure vessel. The
nameplate must be maintained in a
legible condition such that it may be
easily read.

pressure vessel, the information
required by paragraph (a) of this section
must be stamped on a nameplate
permanently attached to the pressure
vessel when the pressure vessel is
constructed of—
(1) Steel plate less than one-fourth

§ 54.10–25 Manufacturers’ data report
forms (modifies UG–120).
(a) The Manufacturers’ data report
form, as provided by the Coast Guard,
must be completed in duplicate and
certified by the manufacturer for each
pressure vessel required to be shop
inspected under these regulations. The
original of this form must be delivered
to the Coast Guard inspector.
(b) Data forms for those parts of a
pressure vessel requiring inspection,
which are furnished by other than the
shop of the manufacturer responsible for
the completed unit, must be executed in
triplicate by the manufacturer of the
parts. The original and one copy must
be delivered to the Coast Guard
inspector who must forward one copy of
the report to the Officer in Charge,
Marine Inspection, having cognizance
over the final assembly. These partial
data reports, together with the final
inspection and tests, must be the final
Coast Guard inspector’s authority to
apply the Coast Guard symbol and
number. A final data report must be
executed by the manufacturer or
assembler who completes the final
assembly and tests.
(c) If a pressure vessel is required to
be inspected in accordance with
§ 54.10–3(c), the manufacturer’s data
reports required by UG–120 must be
made available to the Coast Guard
inspector for review prior to inspection
of the pressure vessel.

Definitions (modifies appendix
Definitions applicable to this subpart
are in § 52.01–3 of this subchapter.
§ 54.15–5
UG–125).
Protective devices (modifies
(a) All pressure vessels must be
provided with protective devices. The
protective devices must be in
accordance with the requirements of
UG–125 through UG–136 of Section VIII
of the ASME BPVC (incorporated by
reference; see § 54.01–1) except as
modified in this subpart.
(b) An unfired steam boiler evaporator
or heat exchanger (see § 54.01–10) must
be equipped with protective devices as
required by § 54.15–15.
(c) All pressure vessels other than
unfired steam boilers must be protected
by pressure-relieving devices that will
prevent the pressure from rising more
than 10 percent above the maximum
allowable working pressure, except
when the excess pressure is caused by
exposure to fire or other unexpected
source of heat.
(d) Where an additional hazard can be
created by exposure of a pressure vessel
to fire or other unexpected sources of
external heat (for example, vessels used
to store liquefied flammable gases),
supplemental pressure-relieving devices
must be installed to protect against
excessive pressure. Such supplemental
pressure-relieving devices must be
capable of preventing the pressure from
rising more than 20 percent above the
maximum allowable working pressure
of the vessel. The minimum required
relief capacities for compressed gas
pressure vessels are given under
§ 54.15–25. A single pressure-relieving
device may be used to satisfy the
requirements of this paragraph and
paragraph (c) of this section, provided it
meets the requirements of both
paragraphs.
(e) Pressure-relieving devices should
be selected on the basis of their
intended service. They must be
constructed, located, and installed so
that they are readily accessible for
inspection and repair and so arranged
that they cannot be readily rendered
inoperative.
(f) Where pressure-indicating gages
are used, they must be chosen to be
compatible with the pressure to be
indicated. The size of the visual display,
the fineness of graduations, and the
orientation of the display will be

considered. In no case must the upper
range of the gage be less than 1.2 times
nor more than 2 times the pressure at
which the relieving device is set to
function.
(g) The Commandant may authorize
or require the use of a rupture disk in
lieu of a relief or safety valve under
certain conditions of pressure vessel use
and design. See § 54.15–13.
(h) Vessels that are to operate
completely filled with liquid must be
equipped with liquid relief valves
unless otherwise protected against
overpressure.
(i) The protective devices required
under paragraph (a) of this section must
be installed directly on a pressure vessel
except when the source of pressure is
external to the vessel, and is under such
positive control that the pressure in the
vessel cannot exceed the maximum
allowable working pressure at the
operating temperature except as
permitted in paragraphs (c) and (d) of
this section.
(j) Pressure-relieving devices must be
constructed of materials suitable for the
pressure, temperature, and other
conditions of the service intended.
(k) The opening through all pipes and
fittings between a pressure vessel and
its pressure-relieving device must have
at least the area of the pressure-relieving
device inlet, and in all cases must have
sufficient area so as not to unduly
restrict the flow to the pressurerelieving device. The opening in the
vessel must be designed to provide
direct and unobstructed flow between
the vessel and its pressure-relieving
device.
(l) Safety devices need not be
provided by the pressure vessel
manufacturer. However, overpressure
protection must be provided prior to
placing the vessel in service.
§ 54.15–10 Safety and relief valves
(modifies UG–126).
(a) All safety and relief valves for use
on pressure vessels or piping systems
must be designed to meet the protection
and service requirements for which they
are intended and must be set to relieve
at a pressure which does not exceed the
‘‘maximum allowable working
pressure’’ of the pressure vessel or
piping system. Relief valves are not
required to have huddling chambers for
other than steam service. In addition,
safety valves used on vessels in which
steam is generated must meet the
standards in § 52.01–120 of this
subchapter except § 52.01–120(a)(9). For
steam service below 206 kPa (30 psig),
bodies of safety valves may be made of
cast iron. Safety relief valves used in
liquefied compressed gas service must

meet the standards in subpart 162.017
or 162.018 in subchapter Q of this
chapter as appropriate.
(b) Pilot-valve control or other
indirect operation of safety valves is not
permitted unless the design is such that
the main unloading valve will open
automatically at not over the set
pressure and will discharge its full rated
capacity if some essential part of the
pilot or auxiliary device should fail. All
other safety and relief valves shall be of
the direct spring-loaded type.
(c) Safety and relief valves for steam
or air service must be provided with a
substantial lifting device so that the disk
can be lifted from its seat when the
pressure in the vessel is 75 percent of
that at which the valve is set to blow.
(d) Safety and relief valves for service
other than steam and air need not be
provided with a lifting device although
a lifting device is desirable if the vapors
are such that their release will not create
a hazard.
(e) If the design of a safety or relief
valve is such that liquid can collect on
the discharge side of the disk, the valve
must be equipped with a drain at the
lowest point where liquid can collect
(for installation, see UG–134 of Section
VIII of the ASME BPVC (incorporated by
reference; see § 54.01–1)).
(f) Cast iron may be employed in the
construction of relief valves for
pressures not exceeding 125 pounds per
square inch and temperatures not
exceeding 450 °F. Seats or disks of cast
iron are prohibited.
(g) The spring in a relief valve in
service for pressures up to and
including 250 pounds per square inch
must not be reset for any pressure more
than 10 percent above or 10 percent
below that for which the relief valve is
marked. For higher pressures, the spring
must not be reset for any pressure more
than 5 percent above or 5 percent below
that for which the relief valve is marked.
(h) The rated relieving capacity of
safety and relief valves for use on
pressure vessels must be based on actual
flow test data and the capacity must be
certified by the manufacturer in
accordance with one of the following:
(1) 120 percent of the valve set
pressure for valves rated in accordance
with CGA S–1.2 (incorporated by
reference; see § 54.01–1).
(2) 110 percent of the valve set
pressure for valves rated in accordance
with UG–131 of Section VIII of the
ASME BPVC.
(3) 103 percent of the valve set
pressure for steam in accordance with
PG–69 of Section VIII of the ASME
BPVC.

127).
Rupture disks (modifies UG–
(a) Paragraph UG–127 of Section VIII
of the ASME BPVC (incorporated by
reference; see § 54.01–1) provides for
the use of rupture disks in series with
spring loaded safety or relief valves.
(b) For certain pressure vessels
containing substances which may
render a relief or safety valve
inoperative, or where the installation of
a valve is considered impractical, the
Commandant may authorize or require
the use of a rupture disk in parallel with
or in lieu of a spring-loaded safety or
relief valve. These rupture disks must:
(1) Comply with the general
provisions of § 54.15–5 except as noted
otherwise in this section;
(2) Have a capacity for discharge such
that the volume of release is sufficient
to prevent the internal pressure from
exceeding 120 percent of the ‘‘maximum
allowable working pressure’’ with the
pressure vessel exposed to fire
conditions (see § 54.15–25); and,
(3) Operate at a pressure level which
does not produce fatigue failure of the
disk. The normal maximum operating
pressure multiplied by 1.3 must not
exceed the nominal disk burst pressure.
(Notice that this restriction for
protection of the rupture disk will
usually require operation below the
‘‘maximum allowable working
pressure’’ of the pressure vessel and
therefore should be considered in
design.)
(c) All disks must be oriented so that
if rupture occurs, the disk fragments and
pressure vessel discharge will be
directed away from operating personnel
and vital machinery.
§ 54.15–15 Relief devices for unfired steam
boilers, evaporators, and heat exchangers
(modifies UG–126).
(a) An approved safety valve set to
relieve at a pressure not exceeding the
‘‘maximum allowable working
pressure’’ of the shell must be fitted to
all unfired steam boilers and
evaporators except for evaporators of the
atmospheric type designed for vapor
discharge direct to a distiller with no
shutoff valve in the discharge line. The
distiller connected to atmospheric
evaporators must be fitted with a vent
to prevent a buildup in pressure. In no
case must the vent be less than 1.5
inches in diameter. Evaporators
operating between atmospheric pressure
and 15 psig, may use a rupture disc as
an alternative to the safety valve.
(b) Safety valves for use on pressure
vessels in which steam or pressure is
generated must comply with the
requirements of § 54.15–10. Rupture
discs used in lieu of these safety valves,
PO 00000
Frm 00063
Fmt 4701

as provided for in paragraph (a) of this
section, must comply with the
requirements of § 54.15–13.
(c) The relieving capacity of
evaporator safety valves required by
paragraph (a) of this section must be at
least equal to the capacity of the orifice
fitted in the steam supply to the
evaporator. The orifice capacity must be
determined in accordance with the
formula in paragraph (c)(1) or (2) of this
section as appropriate:
(1) Where the set pressure of the
evaporator shell safety valve is 58
percent or less than the setting of the
safety valve in the steam supply:

(2) Where the set pressure of the
evaporator shell safety valve exceeds 58
percent of the setting of the safety valve
on the steam supply:

A = Cross-sectional area of rounded entrance
orifice, in square inches. The orifice
must be installed near the steam inlet or
the coils or tubes and where no orifice
is employed the area used in the formula
must be that of the inlet connection or
manifold.
P = Set pressure of steam supply safety valve,
in pounds per square inch, absolute.
P1 = Set pressure of evaporator shell safety
valve, in pounds per square inch,
absolute.
(d) The relieving capacity of safety
valves on unfired steam boilers must not
be less than the maximum generating
capacity of the unfired steam boiler as
certified by the manufacturer.
(e) On new installations and where
the orifice size of an existing unfired
steam boiler or evaporator is increased,
an accumulation test must be made by
closing all steam outlet connections
except the safety valves for a period of
five minutes. When conducting the
accumulation test, the water must be at
the normal operating level and the
steam pressure must be at the normal
operating pressure, and while under this
test the pressure must not rise more
than 6 percent above the safety valve
setting.
(f) A heat exchanger with liquid in the
shell and the heating medium in the
tubes or coils, must be fitted with a
liquid relief valve meeting the
requirement of § 54.15–5.
(g)(1) A heat exchanger with steam in
the shell and liquid in the tubes or coils
at a pressure exceeding that in the shell,
must have a liquid relief valve fitted to
protect the shell against excess pressure.

Federal Register / Vol. 89, No. 114 / Wednesday, June 12, 2024 / Rules and Regulations
§ 54.30–3
Introduction.
(a) Large conventional pressure
vessels used to transport liquefied
petroleum and natural gases, at ‘‘low
temperatures’’ may often be difficult to
thermally stress relieve. Where no other
problem, such as corrosion exists,
mechanical stress relief will be
permitted for Class II–L pressure
vessels.
(b) Mechanical stress relief serves to
cause small flaws, particularly in the
weld zone, to yield plastically at the
flaw tip resulting in a local relief of
stress and a blunting of the crack tip. To
achieve the maximum benefit from
mechanical stress relief, it is necessary
that the stresses so imposed be more
severe than those expected in normal
service life. At the same time, it is
necessary that the stresses which are
imposed are not so high as to result in
appreciable deformation or general
yielding.
(c) The weld joint efficiencies as
listed in table UW–12 of Section VIII of
the BPVC (incorporated by reference;
see § 54.01–1) apply except that a
minimum of spot radiography will be
required. UW–12(c) of Section VIII of
the ASME BPVC that permits omitting
all radiography does not apply. Spot
examination must follow UW–52 of
Section VIII of the ASME BPVC and, in
addition, these vessels will be required
to have radiographic examination of
intersecting circumferential and
longitudinal joints for a distance of at
least 20 times the plate thickness from
the junction. See § 54.25–8 on spot
radiography.
(d) Severe cold forming will not be
permitted unless thermal stress relief is
used. For example, parts of the vessels
which are individually cold formed,
such as heads, must be thermally stress
relieved, where the extreme fiber strain
measured at the surface exceeds 5
percent as determined by:
Percent strain = (65t/Rf)[1¥(Rf/Ro)]
where:
t = Plate thickness.
Rf = Final radius.
Ro = Original radius (equals infinity for flat
plate).

§ 54.30–5
Limitations and requirements.
(a) Class II–L pressure vessels which
require stress relief (see table 2 to
§ 54.01–5) may be mechanically stress
relieved provided:
(1) The steels from which they are
fabricated do not specifically require
thermal stress relief in UCS–56 of
Section VIII of the ASME BPVC
(incorporated by reference; see § 54.01–
1) and have a ratio of yield to ultimate
tensile strength not greater than 0.8. For
VerDate Sep<11>2014
18:22 Jun 11, 2024
Jkt 262001
example: A–537 steels could be
mechanically stress relieved.
(2) Pressure difference across the shell
is not greater than 100 pounds per
square inch, thickness of shell is not
greater than 1 inch, and the design
temperature is not greater than 115 °F.
(3) It will carry liquids of specific
gravity no greater than 1.05.
(4) Design details are sufficient to
eliminate stress concentrators:
Mechanical stress relief is not
acceptable in designs involving the
following types of welded connections
shown in UW–16.1 of Section VIII of the
ASME BPVC:
(i) Types l, m, n, and p because of
nonintegral reinforcement. Type o will
be acceptable provided the plate,
nozzle, and reinforcement assembly are
furnace stress relieved and the
reinforcement is at least 6 inches or 10t,
whichever is larger, from the plate head.
(ii) Types d, e, and f because
expansion and contraction stresses are
concentrated at the junction points.
(5) That no slip-on flanges in sizes
greater than 2 inches are used.
(6) The categories A and B joints are
type one as described in table UW–12 of
Section VIII of the ASME BPVC and all
categories C and D joints are full
penetration welds. See UW–3 of the
ASME BPVC for definition of categories.
(b) When a pressure vessel is to be
mechanically stress relieved in
accordance with § 54.30–10(a)(1), its
maximum allowable working pressure
will be 40 percent of the value which
would otherwise be determined.
However, an increase of this 40 percent
factor may be permitted if the stress
relief is carried out at a pressure higher
than that required by § 54.30–10(a)(1)
and an experimental strain analysis is
carried out during stress relief. This
evaluation should provide information
as to the strains at the saddles, welded
seams and nozzles as well as the body
of the vessel. The hydrostatic pressure
applied during stress relief should be
such that, except in the case of welds,
the stresses in the vessel must closely
approach but not exceed 90 percent of
the yield stress of the material at the test
temperature. The proposed
experimental program should be
submitted to the Commandant for
approval prior to its use. Photo-elastic
coating, strain gaging, or a brittle coating
technique is suggested for the
experimental analysis.
§ 54.30–10 Method of performing
mechanical stress relief.
(a) The mechanical stress relief must
be carried out in accordance with the
following stipulations using water as the
pressurizing medium:
PO 00000
Frm 00069
Fmt 4701
Sfmt 4700
50125
(1) At a hydrostatic pressure
(measured at the tank top) of 1.5 times
the design pressure. (See UA–60(e) of
Section VIII of the ASME BPVC
(incorporated by reference; see § 54.01–
1).)
(2) At a temperature of 70 °F or the
service temperature plus 50 °F,
whichever is higher. Where the ambient
temperature is below 70 °F, and use of
water at that temperature is not
practical, the minimum temperature for
mechanical stress relief may be below
70 °F but must not be less than 50 °F
above service temperature.
(3) The stress relief must be at the
required temperature and pressure and
held for a period not less than 2 hours
per inch of metal thickness, but in no
case less than 2 hours.
(b) It is considered preferable that
mechanical stress relief be
accomplished with the tanks in place on
their saddles or supporting structure in
the barge or ship in which they will be
utilized. In any case, it is considered
mandatory that the tank be supported
only by its regular saddles or supporting
structure, without any auxiliary or
temporary supports.
§ 54.30–15 Requirement for analysis and
computation.
(a) A stress analysis must be
performed to determine if the tank may
be exposed to excessive loadings during
the mechanical stress relief process.
This analysis should include
consideration of the local stresses in
way of saddles or other supporting
structure and additional bending
stresses due to the weight of the
pressurizing liquid particularly in areas
of high stress concentration. While it is
necessary that the general stress level
during the process be in excess of the
normal working level, the calculated
maximum stress during test must not
exceed 90 percent of the yield strength
of the material at test temperature. The
supporting structure must be analyzed
to verify its adequacy.
(b) In all cases where the tanks are
mechanically stress relieved in place in
the ship or barge and the tanks are
designed to carry cargoes with a specific
gravity less than 1.05, the ship or barge
must be shown to have adequate
stability and buoyancy, as well as
strength to carry the excess weight of
the tank during the stress relief
procedure.

■ 22. Revise and republish § 56.07–10 to
read as follows:
§ 56.07–10 Design conditions and criteria
(modifies 101–104.7).
(a) Maximum allowable working
pressure. (1) The maximum allowable
working pressure of a piping system
must not be greater than the internal
design pressure defined in 104.1.2 of
ASME B31.1 (incorporated by reference;
see § 56.01–2).
(2) Where the maximum allowable
working pressure of a system
component, such as a valve or a fitting,
is less than that computed for the pipe
or tubing, the system pressure must be
limited to the lowest of the component
maximum allowable working pressures.
(b) Relief valves. (Modifies 101.2.)
(1) Every system, which may be
exposed to pressures higher than the
system’s maximum allowable working
pressure, must be safeguarded by
appropriate relief devices. Relief valves
are required at pump discharges except
for centrifugal pumps so designed and
applied that a pressure in excess of the
maximum allowable working pressure
for the system cannot be developed.
(2) The relief valve setting must not
exceed the maximum allowable working
pressure of the system. Its relieving
capacity must be sufficient to prevent
the pressure from rising more than 20
percent above the system maximum
allowable working pressure. The rated
relieving capacity of safety and relief
valves used in the protection of piping
systems only must be based on actual
flow test data and the capacity must be
certified by the manufacturer at 120
percent of the set pressure of the valve.
(3) Relief valves must be certified as
required in part 50 of this subchapter for
valves, and must also meet the
requirements of § 54.15–10 of this
subchapter.
(c) Ship motion dynamic effects.

designs must account for the effects of
ship motion and flexure, including
weight, yaw, sway, roll, pitch, heave,
and vibration.
(d) Ratings for pressure and
temperature. (Modifies 102.2.) The
material in 102.2 of ASME B31.1
applies, with the following exceptions:
(1) The details of components not
having specific ratings as described in
102.2.2 of ASME B31.1 must be
furnished to the Marine Safety Center
for approval.
(2) Boiler blowoff piping must be
designed in accordance with § 56.50–40.
(e) Pressure design. (Modifies 102.3,
104.1.2, and 104.4.)
(1) Materials for use in piping must be
selected as described in § 56.60–1(a).
Tabulated values of allowable stress for
these materials must be measured as
indicated in 102.3.1 of ASME B31.1.
(2) Allowable stress values, as found
in the ASME BPVC, which are restricted
in application by footnote or are
italicized must not be used. Where
multiple stresses are listed for a
material, the lowest value of the listing
must be used unless otherwise approved
by the Commandant. In all cases, the
temperature is understood to be the
actual temperature of the component.
(3) Where the operator desires to use
a material not listed, permission must
be obtained from the Commandant.
Requirements for testing found in
subpart 56.97 may affect design and
should be considered. Special design
limitations may be found for specific
systems. Refer to subpart 56.50 for
specific requirements.
(f) Intersections. (Modifies 104.3.) The
material in 104.3 of ASME B31.1 is
applicable with the following additions:
(1) Reinforcement calculations where
applicable shall be submitted.
(2) Wherever possible the longitudinal
joint of a welded pipe should not be
pierced.

freeboard deck of a cargo vessel.
(b) Passenger vessels must have
provision made to prevent the
compartment served by any bilge
suction piping from being flooded in the
event the pipe is severed or otherwise
damaged by collision or grounding in
any other compartment. Where the
piping is located within one-fifth of the
beam of the side of the vessel or is in
a duct keel, a nonreturn valve must be
fitted to the end of the pipe in the
compartment, which it serves.
(c)(1) Each bilge suction must lead
from a manifold unless otherwise
approved by the Marine Safety Center.
As far as practicable, each manifold
must be in, or capable of remote
operation from, the same space as the
bilge pump. In either case, the manifold
must be capable of being locally
controlled from the floorplates. As far as
practicable, each overboard-discharge
valve for a bilge system must comply
with the requirements governing
location and accessibility for suction
manifolds. Except as otherwise
permitted by paragraph (c)(3) of this
section for a vessel employing a
common-rail bilge system, each bilge-

remote operation from the space where
the pump is, and is capable of manual
operation.
(iv) The stop valve or the stop-check
valve is accessible under all operating
conditions, and the space used for
access contains no expansion joint or
flexible coupling that, upon failure,
would cause flooding and prevent
access to the valve.
(v) A port and a starboard suction
serve each space protected unless,
under the worst conditions of list and
trim and with liquid remaining after
pumping, the vessel’s stability remains
acceptable, in accordance with
subchapter S of this chapter.
(vi) For each vessel designed for the
carriage of combinations of both liquid
and dry bulk cargoes, no bilge pump or
piping is located in a machinery space
other than in a pump room for cargo,
and no liquid and other cargoes are
carried simultaneously.
(vii) For each cargo vessel in Great
Lakes service, each common-rail piping
for the bilge and ballast system serving
cargo spaces, if installed and if
connected to a dedicated common-rail
bilge system, must lead separately from
a valved manifold located at the pump.
(d) The internal diameter of bilge
suction pipes including strainers must
be determined by formulas 1 and 2 to

arrangements.
(e) Independent bilge suction. One of
the independent bilge pumps must have
a suction of a diameter not less than that
given by formula 2 to § 56.50–50(d)
introductory text that is led directly
from the engine room bilge entirely
independent of the bilge main, and on
passenger vessels each independent
bilge pump located in the machinery
spaces must have such direct suctions
from these spaces, except that not more
than two pumps are required to have
direct suctions from any one space. A
suction that is led directly from a
suitably located pump manifold may be
considered to be independent of the
PO 00000
Frm 00085
Fmt 4701

bilge main. Where two direct suctions
are required in any one compartment on
passenger vessels, one suction must be
located on each side of the
compartment. If watertight bulkheads
separate the engine and boiler rooms, a
direct suction or suctions must be fitted
to each compartment unless the pumps
available for bilge service are distributed
throughout these compartments, in
which case at least one pump in each
such compartment must be fitted with
direct suction in its compartment. In a
vessel with more than one hull, there
must be one bilge pump that has an
independent bilge suction in each hull.
In a column stabilized mobile offshore
drilling unit, the independent bilge
suction must be from the pumproom
bilge.
(f) Emergency bilge suctions. In
addition to the independent bilge
suction(s) required by paragraph (e) of
this section, an emergency bilge suction
must be provided in the machinery
space for all self-propelled vessels as
described in the following
subparagraphs. Emergency suctions
must be provided from pumps other
than those required by § 56.50–55(a).
Such suctions must have nonreturn
valves, and must meet the following
criteria as appropriate:
(1) On passenger vessels propelled by
steam and operating on an international
voyage or on ocean, coastwise, or Great
Lakes routes, the main circulating pump
is to be fitted with a direct bilge suction
for the machinery space. The diameter
of such suctions must not be less than
two-thirds the diameter of the main sea
injection. Other independent power
pumps in the machinery space may be
approved by the Commandant if the
main circulating pump is not suitable.

engine room is to be fitted with the
direct bilge suction in the machinery
space. The area of the suction pipe is to
be equal to the full suction inlet of the
pump.
(3) Vessels over 180 feet in length
which are not passenger vessels, and
which operate on international voyages
or in ocean, coastwise, or Great Lakes
service, must be provided with a direct
emergency bilge suction from any pump
in the machinery space, except that a
required bilge pump may not be used.
The discharge capacity of the pump
selected must exceed the capacity of the
required main bilge pump and the area
of the suction inlet is to be equal to the
full suction inlet of the pump.
(4) Vessels under 180 feet in length
need not provide an emergency bilge
suction, except that passenger vessels
must comply with the requirements of
paragraphs (f)(1) and (2) of this section.
(5) Each vessel with more than one
hull must have an emergency bilge
suction in each hull.
(6) Each column stabilized mobile
offshore drilling unit must have—
(i) An emergency bilge suction in each
hull; and
(ii) A remote control for the
emergency pump and associated valves
that can be operated from the ballast
control room.
(g) Each individual bilge suction must
be fitted with a suitable strainer having
an open area of not less than three times
that of the suction pipe. In addition, a
mud box or basket strainer must be
fitted in an accessible position between
the bilge suction manifold and the
pump.
(h) Pipes for draining cargo holds or
machinery spaces must be separate from
pipes which are used for filling or
emptying tanks where water or oil is
carried. Bilge and ballast piping systems
must be so arranged as to prevent oil or
water from the sea or ballast spaces from
passing into cargo holds or machinery
spaces, or from passing from one
compartment to another, whether from
the sea, water ballast, or oil tanks, by the
appropriate installation of stop and nonreturn valves. The bilge and ballast
mains must be fitted with separate
control valves at the pumps. Piping for
bilge and ballast must be arranged so as
to prevent, by the appropriate
installation of stop and non-return
valves, oil or water from the sea or
ballast spaces from passing into a cargo
hold or machinery space, or from
passing from one compartment to
another, regardless of the source. The
bilge and ballast mains must be fitted
with separate control valves at the
pumps.
(i) Ballast piping must not be installed
to any hull compartment of a wood
vessel. Where the carriage of liquid
ballast in such vessels is necessary,
suitable ballast tanks, structurally
independent of the hull, must be
provided.

access through the vent to below deck
must be at least 30 inches (760mm) on
the freeboard deck, 24 inches (610mm)
on the raised quarterdeck, and 12 inches
(305mm) on other superstructure decks.
Where the height of vents may interfere
with the working of the vessel, a lower
height may be approved by the Marine
Safety Center provided the vent cap is
properly protected from mechanical
damage. For barges in inland service,
the vents must extend at least 6 inches
above the deck.
(7) Satisfactory means, permanently
attached, must be provided for closing
the openings of all vents, except that
barges in inland service may be
exempted. Acceptable means of closure
are:
(i) A ball check valve where the ball
float, normally in the open position,
will float up and close under the action
of a submerging wave. The valve must
be designed so that the effective clear
discharge area through the valve with
the float in the open position is not less
than the inlet area of the vent pipe to
which the valve is connected; or
(ii) Another suitable device acceptable
to the Commanding Officer, Marine
Safety Center.
(8) Vent outlets from all tanks which
may emit flammable or combustible
vapors, such as bilge slop tanks and
contaminated drain tanks, must be fitted
with a single screen of corrosionresistant wire of at least 30 by 30 mesh,
or two screens of at least 20 by 20 mesh
spaced not less than one-half inch

(11) (i) If a tank may be filled by a
pressure head exceeding that for which
the tank is designed, the aggregate crosssectional area of the vents in each tank
must be not less than the cross-sectional
area of the filling line unless the tank is
protected by overflows, in which case
the aggregate cross-sectional area of the
overflows must be not less than the
cross-sectional area of the filling line.
(ii) Provision must be made to guard
against liquids rising in the venting
system to a height that would exceed
the design head of a cargo tank or fueloil tank. It may be made by high-level
alarms, overflow-control systems, or
other, equivalent means.
(12) Vents from freshwater or water
ballast tanks must not be connected to
a common header with vents from oil or
oily ballast tanks.
(b) Unless permitted by the Marine
Safety Center, tank vents must remain

§ 56.50–90
Sounding devices.
(a) Each tank must be provided with
a suitable means of determining liquid
level. Except for a main cargo tank on
a tank vessel, each integral hull tank
and compartment must be fitted with a
sounding pipe or other level indicating
device acceptable to the Marine Safety
Center.
(b) Where sounding pipes terminate
below the freeboard deck on cargo
vessels, they must be fitted with gate
valves. On passenger vessels, where
sounding pipes terminate below the
bulkhead deck, they must be fitted with
gate valves.
(c) Except as allowed by this
paragraph, on each vessel constructed
on or after June 9, 1995, no sounding
pipe used in a fuel-oil tank may
terminate in any space where the risk of
ignition of spillage from the pipe might
arise. None may terminate in a space for
passengers or crew. When the
Commanding Officer, Marine Safety
Center, determines it impracticable to
avoid terminating a pipe in a machinery
space, a sounding pipe may terminate in
a machinery space if all the following
requirements are met:
(1) The fuel-oil tank has an oil-level
gauge complying with paragraph (d) of
this section.
(2) Precautions are taken such as
fitting an effective screen (shield) to
prevent the fuel oil, in case of spillage

through the end of the pipe, from
coming into contact with a source of
ignition.
(3) The end of the pipe is fitted with
a self-closing blanking device.
(d) Other oil-level gauges may be used
instead of sounding pipes if all the
following requirements are met:
(1) In a passenger vessel, no such
gauge may require penetration below
the top of the tank, and neither the
failure of a gauge nor an overfilling of
the tank may permit release of fuel into
the space.
(2) In a cargo vessel, neither the
failure of such a gauge nor an overfilling
of the tank may permit release of fuel
into the space. The use of cylindrical
gauge-glasses is prohibited. The use of
oil-level gauges with flat glasses and
self-closing valves between the gauges
and fuel tanks is acceptable.
(e) The upper ends of sounding pipes
must be closed by a screw cap or plug.
(f) On mobile offshore drilling units
where installation of sounding pipes
may not be practicable for some tanks,
alternate means of determining liquid
level may be used if approved by the
Commandant.

§ 56.50–95 Overboard discharges and
shell connections.
(a)(1) All inlets and discharges led
through the vessel’s side must be fitted
with efficient and accessible valves,
located as close to the hull penetrations
as is practicable.
(2) The number of scuppers, sanitary
discharges, tank overflows, and other
similar openings in the vessel’s side
must be reduced to a minimum, either
by making each discharge serve for as
many as possible of the sanitary and
other pipes, or in any other satisfactory
manner.
(3) In general, when the bulkhead
deck is above the freeboard deck, the
requirements of this section apply
relative to the bulkhead deck. For
vessels not assigned load lines, such as
certain inland vessels and barges, the
weather deck must be taken as the
freeboard deck.
(b)(1) Scuppers and discharge pipes
originating at any level and penetrating
the shell either more than 17.5 inches
(450mm) below the freeboard deck or
less than 23.5 inches (600mm) above the
summer load waterline must be
provided with an automatic nonreturn
valve at the shell. This valve, unless
required by paragraph (b)(2) of this
section, may be omitted if the piping is
not less than Schedule 80 in wall
thickness for nominal pipe sizes
through 8 inches, Schedule 60 for
nominal pipe sizes above 8 inches and
VerDate Sep<11>2014

below 16 inches, and Schedule 40 for
nominal pipe sizes 16 inches and above.
(2) Discharges led through the shell
originating either from spaces below the
freeboard deck, or from within enclosed
superstructures and equivalent
deckhouses on the freeboard deck as
defined in § 42.13–15(i) of subchapter E
of this chapter, must be fitted with
efficient and accessible valves for
preventing water from passing inboard.
Normally each separate discharge must
have one automatic nonreturn valve
with a positive means of closing it from
a position above the freeboard deck.
Where, however, the vertical upward
distance from the summer load line to
the inboard end of the discharge pipe
through which flooding can take place
exceeds 0.01L, the discharge may have
two automatic nonreturn valves without
positive means of closing, provided that
the inboard valve is always accessible
for examination under service
conditions. Where that vertical distance
exceeds 0.02L a single automatic
nonreturn valve without positive means
of closing is acceptable. In an
installation where the two automatic
nonreturn valves are used, the inboard
valve must be above the tropical load
line. The means for operating the
positive action valve must be readily
accessible and provided with an
indicator showing whether the valve is
open or closed. A notice must be posted
at the operating station stating that the
valve must not be closed except as
required in an emergency.
(3) Where scuppers and drains are
installed in superstructures or
deckhouses not enclosed as defined in
§ 42.13–15(j) of subchapter E of this
chapter, they must be led overboard.
Refer to paragraph (b)(1) of this section
for any nonreturn valve requirement.
(c) Overflow pipes which discharge
through the vessel’s side must be
located as far above the deepest load
line as practicable and fitted with valves
as required by paragraph (b) of this
section. Two automatic nonreturn
valves must be used unless it is
impracticable to locate the inboard
valve in an accessible position, in which
case a nonreturn valve with a positive
means of closure from a position above
the freeboard deck will be acceptable.
Overflows which extend at least 30
inches above the freeboard deck before
discharging overboard may be fitted
with a single automatic nonreturn valve
at the vessel’s side. Overflow pipes
which serve as tank vents must not be
fitted with positive means of closure
without the specific approval of the
Marine Safety Center. Overflow pipes
may be vented to the weather.

(d)(1) Sea inlets and discharges, such
as used in closed systems required for
the operation of main and auxiliary
machinery, as in pump connections or
scoop injection heat exchanger
connections, need not meet the
requirements of paragraphs (b)(1) and
(2) of this section but instead must be
fitted with a shutoff valve located as
near the shell plating as practicable, and
may be locally controlled if the valve is
located in a manned machinery space.
These controls must be readily
accessible above the floor plates.
Manned machinery spaces include the
main machinery space and are either
attended by the crew or are automated
in accordance with part 62 of this
subchapter to be comparable to an
attended space.
(2) In unmanned machinery spaces,
all machinery inlets and discharges as
described in paragraph (d)(1) of this
section must be remotely operable from
a position above the freeboard deck
unless otherwise approved and must
meet the access and marking
requirements of paragraph (b)(2) of this
section.
(e)(1) Pipes terminating at the shell
plating must be fitted with bends or
elbows between the outboard openings
and the first rigid connection inboard.
In no case must such pipes be fitted in
a direct line between the shell opening
and the first inboard connection.
(2) Seachests and other hull fittings
must be as short as possible and located
so as to minimize the possibility of
being blocked or obstructed.
(3) The thickness of inlet and
discharge connections outboard of the
shutoff valves, and exclusive of
seachests, must be not less than that of
Schedule 80 for nominal pipe sizes
through 8 inches, Schedule 60 for
nominal pipe sizes above 8 inches and
below 16 inches, and Schedule 40 for
nominal pipe sizes 16 inches and above.
(f) Valves required by this section and
piping system components outboard of
such required valves must be of a steel,
bronze, or ductile cast iron specification
listed in table 1 to § 56.60–1. Lead or
other heat sensitive materials having a
melting point of 1,700 °F or less must
not be used. Brittle materials such as
cast iron must not be used in such
service. Where nonmetallic materials
are used in a piping system, and shell
closures are required by this section, a
positive closure metallic valve is
required (see also § 56.60–25).
(g) The inboard openings of ash and
rubbish-chute discharges must be fitted
with efficient covers. If the inboard
opening is located below the freeboard

valve must be fitted in the chute in any
easily accessible position above the
deepest load line. Means must be
provided for securing both the cover
and the valve when the chute is not in
use. When ash-ejectors or similar
expelling devices located in the boiler
room have the inboard openings below
the deepest load line, they must be
fitted with efficient means for
preventing the accidental admission of
water. The thickness of pipe for ash
ejector discharge must be not less than
Schedule 80.
(h) Where deck drains, soil lines, and
sanitary drains discharge through the
shell in way of cargo tanks on tank
vessels, the valves required by this
section must be located outside the
cargo tanks. These valves must meet the
material requirements of paragraph (f) of
this section. The piping led through
such tanks must be fitted with
expansion bends where required, and
must be of steel pipe having a wall
thickness of not less than Schedule 60,
except that the Commandant will
consider the use of suitable corrosionresistant material of lesser thickness. All
pipe joints within the tanks must be
welded. Soil lines and sanitary drains
which pass through cargo tanks must be
provided with nonreturn valves with
positive means of closing or other
suitable means for preventing the
entrance of gases into living quarters.
(i) Sea valves must not be held open
or closed with locks.

(b) Backing rings. Backing rings must
comply with section 127.2.2. of ASME
B31.1 (incorporated by reference; see
§ 56.01–2).
§ 56.70–10
Preparation (modifies 127.3).
(a) Butt welds—(1) End preparation.
(i) Oxygen or arc cutting is acceptable
only if the cut is reasonably smooth and
true, and all slag is cleaned from the
flame cut surfaces. Discoloration which
may remain on the flame cut surface is
not considered to be detrimental
oxidation.
(ii) Butt-welding end preparation
dimensions contained in ASME B16.25
(incorporated by reference; see § 56.01–
2) or any other end preparation that
meets the procedure qualification
requirements are acceptable.
(iii) If piping component ends are
bored, such boring must not result in
the finished wall thickness after
welding being less than the minimum
design thickness. Where necessary,
weld metal of the appropriate analysis
may be deposited on the inside or
outside of the piping component to
provide sufficient material for
machining to insure satisfactory fitting
of rings.
(iv) If the piping component ends are
upset, they may be bored to allow for a
completely recessed backing ring,
provided the remaining net thickness of
the finished ends is not less than the
minimum design thickness.
(2) Cleaning. Surfaces for welding
must be clean and must be free from
paint, oil, rust, scale, or other material
which is detrimental to welding.
(3) Alignment. The inside diameters
of piping components to be joined must
be aligned as accurately as practicable.
Alignment must be preserved during
welding. Where ends are to be joined
and the internal misalignment exceeds
1⁄16-inch, it is preferred that the
component with the wall extending
internally be internally trimmed (see
Fig. 127.3) so that adjoining internal
surfaces are approximately flush.
However, this trimming must not reduce
a piping component wall thickness
below the minimum design thickness
and the change in the contour may not
exceed 30°.
(4) Spacing. The root opening of the
joint must be as given in the procedure
specification.
(b) Fillet welds. Piping components
that are to be joined utilizing fillet
welds must be prepared in accordance
with applicable provisions and
requirements of this section. For typical

requirements.
ddrumheller on DSK120RN23PROD with RULES2
§ 56.70–15
Procedure (modifies 127.4).
(a) General. (1) Qualification of
welders and welding procedures is
required and must comply with the
requirements of part 57 of this
subchapter.
(2) Sections must be welded insofar as
possible in the fabricating shop.
Welding must not be done in severe
weather conditions. Prior to welding
Class I piping or low temperature
piping, the fabricator must request a
marine inspector to visit their plant to
examine their fabricating equipment
and to witness the qualification tests
required by part 57 of this subchapter.
One test specimen must be prepared for
each process and welding position to be
employed in the fabrication.
(b) Girth butt welds. (1) Girth butt
welds must be complete penetration
welds and may be made with a single
vee, double vee, or other suitable type
of groove, with or without backing rings
or consumable inserts.
(2) Girth butt welds in Class I, I–L,
and II–L piping systems must be double
welded butt joints or equivalent single
welded butt joints for pipe diameters
exceeding three-fourth inch nominal
pipe size. The use of a single welded
butt joint employing a backing ring
(note restrictions in paragraph (b)(3)(iv)
of this section) on the inside of the pipe
is an acceptable equivalent for Class I
and Class II–L applications, but not
permitted for Class I–L applications.
Single welded butt joints employing
either an inert gas for first pass backup
or a consumable insert ring may be
considered the equivalent of a double
welded butt joint for all classes of
piping and is preferable for Class I–L
and II–L systems where double butt
welds cannot be used. A first pass inert
gas backup is intended to mean that the
inside of the pipe is purged with inert
gas and that the root is welded with the
inert gas metal arc (mig) or inert gas
tungsten arc (tig) processes. For single
welded joints, where possible, the
inside of the joint must be examined
visually to assure full penetration.
Radiographic examination of at least 20
percent of single welded joints to check
for penetration is required for all Class
I and Class I–L systems regardless of
size following the requirements of
§ 56.95–10. Ultrasonic testing may be
utilized in lieu of radiographic
examination if the procedures are
approved.
VerDate Sep<11>2014
18:22 Jun 11, 2024
Jkt 262001
(3) For Class II piping, the type of
joints must be similar to Class I piping,
with the following exceptions:
(i) Single-welded butt joints may be
employed without the use of backing
rings in all sizes provided that the weld
is chipped or ground flush on the root
side of the weld.
(ii) For services such as vents,
overflows, and gravity drains, the
backing ring may be eliminated, and the
root of the weld need not be ground.
(iii) Square-groove welds without
edge preparation may be employed for
butt joints in vents, overflows, and
gravity drains where the pipe wall
thickness does not exceed threesixteenth inch.
(iv) The crimped or forged backing
ring with continuous projection around
the outside of the ring is acceptable only
for Class II piping. The projection must
be completely fused.
(4) Tack welds that become part of the
finished weld must be made by a
qualified welder. Tack welds that have
cracked must be removed.
(5) When components of different
outside diameters are welded together,
the weld joint must be filled to the
outside surface of the component having
the larger diameter. There must be a
gradual transition, not exceeding a slope
of 1:3, in the weld between the two
surfaces. To avoid unnecessary weld
deposit, the outside surface of the
component having the larger diameter
must be tapered at an angle not to
exceed 30 degrees with the axis of the
pipe. (See Fig. 127.4.2 of ASME B31.1
(incorporated by reference; see § 56.01–
2).)
(6) As-welded surfaces are permitted;
however, the surface of the welds must
be sufficiently free from coarse ripple,
grooves, overlaps, abrupt ridges and
valleys to meet the following:
(i) The condition of finished welds
must be suitable for radiographic and
other nondestructive examinations
when required by § 56.95–10. In those
cases where there is a question
regarding the surface condition on the
interpretation of a radiographic film, the
film must be compared to the actual
weld surface for interpretation and
determination of acceptability.
(ii) Reinforcements are permitted in
accordance with table 1 to § 56.70–15.
(iii) Undercuts must not exceed 1⁄32inch and must not encroach on the
minimum required section thickness.
(iv) If the surface of the weld requires
grinding to meet the above criteria, care
must be taken to avoid reducing the
weld or base material below the
minimum required thickness.

(7) The type and extent of
examination required for girth butt
welds is specified in § 56.95–10.
(8) Sections of welds that are shown
by radiography or other examination to
have any of the following type of
imperfections must be judged
unacceptable and must be repaired as
provided in paragraph (f) of this section:
(i) Any type of crack or zone of
incomplete fusion or penetration.
(ii) Any slag inclusion or porosity
greater than specified as acceptable in
PW–51 of Section I of the ASME BPVC
(incorporated by reference; see § 56.01–
2).
(iii) Undercuts in the external surfaces
of butt welds more than 1⁄32-inch deep.
(iv) Concavity on the root side of full
penetration girth butt welds where the
resulting weld thickness is less than the
minimum pipe wall thickness required
by this subchapter. Weld reinforcement
up to a maximum of 1⁄32-inch thickness
may be considered as pipe wall
thickness in such cases.
(c) Longitudinal butt welds.
Longitudinal butt welds in piping
components not made in accordance
with the standards and specifications
listed in § 56.60–1 must meet the
requirements of paragraph 127.4.3 of
ASME B31.1 (incorporated by reference;
see § 56.01–2).
(d) Fillet welds. (1) Fillet welds may
vary from convex to concave. The size
of a fillet weld is determined as shown
in Figure 127.4.4A in ASME B31.1.
Fillet weld details for socket-welding
components must meet § 56.30–5(c).
Fillet weld details for flanges must meet
§ 56.30–10(c). Fillet weld details for
flanges must meet § 56.30–10.
(2) The limitations on cracks and
undercutting set forth in paragraph
(b)(8) of this section for girth welds are
also applicable to fillet welds.
(3) Class I piping not exceeding 3
inches nominal pipe size and not
subject to full radiography by § 56.95–10
may be joined by sleeves fitted over
pipe ends or by socket type joints.
Where full radiography is required, only
butt type joints may be used. The inside
diameter of the sleeve must not exceed
the outside diameter of the pipe or tube
by more than 0.080 inch. Fit between
socket and pipe must conform to
applicable standards for socket weld
fittings. Depth of insertion of pipe or
tube within the socket or sleeve must
not be less than three-eighths inch. The
fillet weld must be deposited in a
minimum of two passes, unless
specifically approved otherwise.
Requirements for joints employing
socket weld and slip-on flanges are in
§ 56.30–10.

tubing joined. The fillet welds must be
deposited in a minimum of two passes,
unless specifically approved otherwise.
Requirements for joints employing
socket weld and slip-on flanges are in
§ 56.30–10.
(e) Seal welds. (1) Where seal welding
of threaded joints is performed, threads
must be entirely covered by the seal
weld.
(2) The limitation on cracks and
undercutting set forth in paragraph
(b)(8) of this section for girth welds are
also applicable to seal welds.
(f) Weld defect repairs. (1) All defects
in welds requiring repair must be
removed by a flame or arc-gouging,
grinding, chipping, or machining.
Repair welds must be made in
accordance with the same procedures
used for original welds, or by another
welding process if it is a part of a
qualified procedure, recognizing that
the cavity to be repaired may differ in
contour and dimensions from the
original joint. The types, extent, and
method of examination and limits of
imperfections of repair welds must be
the same as for the original weld.
(2) Preheating may be required for
flame-gouging or arc-gouging certain
alloy materials of the air hardening type
in order to prevent surface checking or
cracking adjacent to the flame or arcgouged surface.
(g) Welded branch connections. (1)

butt, lapped, or scarfed joints. If of the
latter type, the kerf of the material must
be not less than 60°.
(c) Brazing, general. (1) Heat must be
applied evenly and uniformly to all
parts of the joint in order to prevent
local overheating.
(2) The members to be joined must be
held firmly in place until the brazing
alloy has set so as to prevent any strain
on the joint until the brazing alloy has
thoroughly solidified. The brazing must
be done by placing the flux and brazing
material on one side of the joint and
applying heat until the brazing material
flows entirely through the lap and
shows uniformly along the seam on the
other side of the joint. Sufficient flux
must be used to cause the brazing
material to appear promptly after
reaching the brazing temperature.

examination must be made.
(1) 100 percent radiography is
required for all Class I, I–L, and II–L
piping with wall thickness equal to or
greater than 10 mm (0.393 in.).
ddrumheller on DSK120RN23PROD with RULES2
Note 1 to paragraph (a)(1): Throughout
this this section, where for some reason, such
as joint configuration, radiography is not
applicable, another approved examination
may be utilized.
(2) Nondestructive examination is
required for all Class II piping equal to
or greater than 18 inches nominal
diameter regardless of wall thickness.
Any test method acceptable to the
Officer in Charge, Marine Inspection
may be used.
(3) Nondestructive examinations of
other piping systems are required only
when deemed necessary by the Officer
in Charge, Marine Inspection (OCMI).
(b) Visual examination. Visual
examination consists of observation by
the marine inspector either before,
during, or after manufacture,
fabrication, assembly, or test. All welds,
pipe and piping components must
comply with the limitations on
imperfections specified in the product
specification or with the limitations on
imperfections specified in § 56.70–
15(b)(7) and (8), and (c), as applicable.
(c) Nondestructive types of
examinations—(1) 100 Percent
radiography. Where 100 percent
radiography is required, each weld in
the piping must be completely
radiographed. If a butt weld is examined
by radiography, for either random or
100 percent radiography, the method
used must be as follows:
(i) X-ray or gamma ray method of
radiography may be used. The selection
of the method must be dependent upon
its adaptability to the work being
radiographed. The procedure to be
followed must be as indicated in PW–
51 of Section I of the ASME BPVC
(incorporated by reference; see § 56.01–
2).
(ii) If a piping component or a weld
other than a butt weld is radiographed,
the method used must be in accordance
with UW–51 of Section VIII of the
ASME BPVC (incorporated by reference;
see § 56.01–2).
(2) Random radiography. Where
random radiography is required, one or
more welds may be completely or
partially radiographed. Random
VerDate Sep<11>2014
18:22 Jun 11, 2024
Jkt 262001
radiography is desirable in field
welding, where conditions such as
position, temperatures, and cleanliness
are not as controlled as in shop welding.
It may be employed whenever an Officer
in Charge, Marine Inspection questions
a pipe weld not otherwise required to be
tested. The standards of acceptance are
the same as for 100 percent radiography.
(3) Ultrasonic. Where 100 percent
ultrasonic testing is specified, the entire
surface of the weld being inspected
must be covered using careful methods
to be sure that a true representation of
the actual conditions is obtained. The
procedures to be used must be
submitted to the Commandant for
approval.
(4) Liquid penetrant. Where liquid
penetrant examination is required, the
entire surface of the weld being
examined must be covered. The
examination must be performed in
accordance with appendix VIII to
Section VIII of the ASME BPVC. The
following standards of acceptance must
be met:
(i) All linear discontinuities and
aligned penetrant indications revealed
by the test must be removed. Aligned
penetrant indications are those in which
the average of the center-to-center
distances between any one indication
and the two adjacent indications in any
straight line is less than three-sixteenths
inch. All other discontinuities revealed
on the surface need not be removed
unless the discontinuities are also
revealed by radiography, in which case
the pertinent radiographic specification
applies.
(ii) [Reserved]
(5) Magnetic particle. Where magnetic
particle testing is required, the entire
surface of the weld being examined
must be covered. The testing must be
performed in accordance with
Appendix VI to Section VIII of the
ASME BPVC. The following standards
of acceptance are required for welds. All
linear discontinuities and aligned
indications revealed by the test must be
removed. Aligned indications are those
in which the average of the center-tocenter distances between any one
indication and the two adjacent
indications in any straight line is less
than three-sixteenths inch. All other
revealed discontinuities need not be
removed unless the discontinuities are
also revealed by radiography, in which
case the requirements of paragraph
(c)(1) of this section must be met.

in lieu of 137 of ASME B31.1
(incorporated by reference; see § 56.01–
2). Those paragraphs reproduced are so
noted.
(b) Leak tightness. It is mandatory that
the piping constructed demonstrates
leak tightness. Except where otherwise
permitted, this requirement must be met
by a hydrostatic leak test prior to initial
operations. Where a hydrostatic test is
not practicable, a pneumatic test
(§ 56.97–35) or initial service leak test
(§ 56.97–38) may be substituted if
approved by the Commandant.
(1) At no time during the hydrostatic
test may any part of the piping system
be subjected to a stress greater than 90
percent of its yield strength (0.2 percent
offset) at test temperature.
(2) Pneumatic tests may be used in
lieu of the required hydrostatic test
(except as permitted in paragraph (b)(3)
of this section), only when—
(i) Piping subassemblies or systems
are so designed or supported that they
cannot be safely filled with water; or
Note 1 to paragraph (b)(2)(i): These tests
may be made with the item being tested
partially filled with water, if desired.
(ii) Piping systems are to be used in
services where traces of water cannot be
tolerated and, whenever possible, the
piping subassemblies or system have
been previously hydrostatically tested to
the pressure required in § 56.97–30(e).
(3) A pneumatic test at a pressure not
to exceed 25 psig may be applied before
a hydrostatic or a pneumatic test as a
means of locating major leaks. The
preliminary pneumatic test must be
carried out in accordance with the
requirements of § 56.97–35.
Note 2 to paragraph (b)(3): Compressed gas
is hazardous when used as a testing medium.
It is, therefore, recommended that special
precautions for protection of personnel be
taken whenever gas under pressure is used as
the test medium.
§ 56.97–5 Pressure testing of nonstandard
piping system components.
(a) All nonstandard piping system
components such as welded valves and
fittings, nonstandard fittings, manifolds,
seacocks, and other appurtenances must
be hydrostatically tested to twice the
rated pressure stamped thereon, except
that no component should be tested at
a pressure causing stresses in excess of
90 percent of its yield strength.
(b) Items for which an accepted
standard appears in table 2 to § 56.60–
1 need not be tested as described in
paragraph (a) of this section, but need
only meet the test required in the
applicable standard.

flange or equivalent means.
(e) Treatment of flanged joints
containing blinds. Flanged joints at
which blinds are inserted to blank off
other equipment during the test need
not be tested.
(f) Precautions against test medium
expansion. If a pressure test is to be
maintained for a period of time and the
test medium in the system is subject to
thermal expansion, precautions must be
taken to avoid excessive pressure. A
small relief valve set to 1 1/3 times the
test pressure is recommended during
the pressure test.

regions of high stress, such as regions
around openings and thicknesstransition sections.
(e) Minimum required hydrostatic test
pressure. Except as otherwise permitted
in paragraph (f) of this section or
§ 56.97–40, piping systems must be
subjected to a hydrostatic test pressure
that at every point in the system is not
less than 1.5 times the maximum
allowable working pressure.
(f) Maximum permissible hydrostatic
test pressure. (1) When a system is
tested hydrostatically, the test pressure
must not exceed the maximum test
pressure of any component such as
vessels, pumps, or valves in the system.
(2) At no time during the hydrostatic
test may any part of the piping system
be subjected to a stress greater than 90
percent of its yield strength (0.2 percent
offset) at test temperature.
(g) Hydrostatic test pressure holding

must be examined before pressure is
applied to ensure that it is tight and that
all items that should not be subjected to
the test pressure have been
disconnected or isolated by valves or
other suitable means.
(d) Procedure for applying pressure.
The pressure in the system must
gradually be increased to not more than
one-half of the test pressure, after which
the pressure is increased in steps of
approximately one-tenth of the test
pressure until the required test pressure
has been reached.
(e) Examination for leakage after
application of pressure. Following the
application of pressure for the time
specified in paragraph (h) of this

time as may be necessary to conduct the
examination for leakage required in
§ 56.97–30(d).
§ 56.97–38 Initial service leak test
(modifies 137.7).
(a) An initial service leak test and
inspection is acceptable when other
types of test are not practical or when
leak tightness is conveniently
demonstrable due to the nature of the
service. One example is piping where
shut-off valves are not available for
isolating a line. Others may be systems
for service water, condensate, plant and
instrument air, etc., where checking out
of pumps and compressors afford ample
opportunity for leak tightness
inspection prior to full-scale operation.
(b) The piping system must be
gradually brought up to design pressure.
After inspection of the piping system
has proven that the installation is
complete and all joints are leak-tight,
the piping has met the requirements of

Installation tests.
(a) The following piping systems must
be hydrostatically leak tested in the
presence of a marine inspector at a
pressure of 1.5 times the maximum
allowable working pressure of the
system:
(1) Class I steam, feedwater, and
blowoff piping. Where piping is
attached to boilers by welding without
practical means of blanking off for
testing, the piping must be subjected to
the same hydrostatic pressure to which
the boiler is tested. The maximum
allowable working pressures of boiler
feedwater and blowoff piping must be
the design pressures specified in
§§ 56.50–30(a)(3) and 56.50–40(b) of this
subpart, respectively.
(2) Fuel oil discharge piping between
the pumps and the burners.

In the case of single vessel fabrication,
a set of test plates is required for each
300 lineal feet of weld or fraction
thereof. In the case of multiple vessel
fabrication where each increment of 300
lineal feet of weld involves more than
one pressure vessel, the set of test plates
must be prepared at the time of
fabrication of the first vessel involving
that increment.
§ 57.06–3 Method of performing
production testing.
(a) Except as otherwise specified in
this section a test plate must be attached
to the shell plate on one end of the
longitudinal joint of each vessel as
shown in figure 1 to § 57.06–3(d), so
that the edges of the test plate to be
welded are a continuation of and
duplication of the corresponding edges
of the longitudinal joint. For attached
test plates, the weld metal must be
deposited in the test plate welding
groove continuously with the weld
metal deposited in the groove of the
longitudinal joint. As an alternate
method, the marine inspector may
permit the use of separate test plates,
provided the same welding process,
procedure, and technique employed in
the fabrication of the longitudinal joint
are used in welding the test plates.
(b) All test plates, whether attached to
the shell or separate in accordance with
paragraphs (a) and (d) of this section,
must be prepared from material of the
same specification, thickness, and heat
treatment and, for Class I–L and Class
II–L vessels, the same heat as that of the
vessel for which they are required.
However, except when required to be
from a specific heat, test plates may be
prepared from material of a different
product form, such as plate in lieu of a
forging, provided the chemical
composition is within the vessel
material specification limits and the
melting practice is the same.
(c) Test plates are not required for
welded nozzle attachments.
(d) In the case of vessels having no
longitudinal welded joints, at least one
set of test plates must be welded for
each vessel, using the circumferential
joint process, procedure, and technique,
except that the provisions of § 57.06–
2(a) also apply for Classes I and I–L
vessels, and that the provisions of
§ 57.06–2(a) and (c) also apply for
Classes II and II–L vessels.

(e) Test plates must be made by the
same welder producing the longitudinal
and circumferential joints. If more than
one welder is employed in the welding
of the pressure vessel(s), the test plates
must be made by the welder designated
by the marine inspector. The test plates
must be of the same thickness as the
material being welded and must be of
sufficient size to provide two specimens
of each type required, except that in the
case of pressure vessels having no
longitudinal seams, the test plate need
be only of sufficient length to provide
one set of test specimens, and if a retest
is necessary, an additional set of test
plates may be welded separately.

requirements.
(a) For test plates three-fourths inch or
less in thickness one reduced section
tensile specimen and two free-bend
specimens must be tested. For plates
exceeding three-fourths inch in
thickness one reduced section tensile
specimen, one free-bend specimen and
one guided side bend specimen must be
tested. In addition, boiler drums of
thickness five-eighths inch or greater
must have a tension test specimen of the
weld metal as required by paragraph
(f)(2) of this section. Toughness tests are
required for Classes I–L and II–L
pressure vessels as specified in § 57.06–

welding does not throw the finished test
plate out of line by an angle of over 5°.
(c) Where the welding has warped the
test plates, the plates must be
straightened before being stressrelieved. The test plates must be
subjected to the same stress-relieving
operation as required by this subchapter
for the pressure vessel itself. At no time
must the test plates be heated to a
temperature higher than that used for
stress-relieving the vessel.
(d) The bend specimens must be taken

(e) In submitting the samples for test
the manufacturer must state the
minimum and maximum tensile range
of the base metal.
(f) The external appearances of the
welds and the amount of weld
reinforcement shall conform to the
requirements for fabrication, and the
maximum reinforcement for the test
plates must not exceed the maximum
permitted for construction.
(1) The tension-test specimen of the
joint must be transverse to the welded
joint and must be of the full thickness
of the plate after the weld reinforcement
has been machined flush. The form and

dimensions must be as shown in figure
3 to § 57.06–4(f). When the capacity of
the available testing machine does not
permit testing a specimen of the full
thickness of the welded plate, the
specimen may be cut with a thin saw
into as many portions of the thickness
as necessary, as shown in figure 4 to
§ 57.06–4(f) each of which must meet
the requirements. The tensile strength of
the joint specimen when it breaks in the
weld must not be less than the
minimum of the specified tensile range
of the plate used. If the specimen breaks
in the plate at not less than 95 percent
of the minimum specified tensile range

thicknesses of five-eighths inch or
greater 2 to § have a tension-test
specimen of the weld metal machined to
form as shown in figure 5 to § 57.06–4(f)
taken entirely from the deposited metal.

(g) The freebend specimens must be of
the form and dimensions shown in
figure 6 to § 57.06–4(g). For plates of
three-fourths inch or less in thickness
one of the specimens must be bent with
the face of the weld in tension. Each
freebend specimen must be bent cold
under freebending conditions until the
elongation measured within or across
approximately the entire weld on the
outer surface of the bend is at least 30
percent, except that for Class II and
Class II–L pressure vessels, the
minimum elongation must be 20
percent. When the capacity of the
available testing machine will not
permit testing a full thickness specimen,
the specimen may be cut with a thin
saw into as many portions of the
thickness as necessary as shown in
figure 4 to § 57.06–4(f), provided each
such piece retains the proportion of 1.5

1). The specimen must withstand being
bent cold to the full capacity of the jig
without developing any crack exceeding
one-eighth inch in any direction. Where
the plate thickness exceeds two inches,
the specimen must be cut in two so that
each portion does not exceed 2 inches
in width. Each such portion must be
tested and must meet the requirements.

(d) Cracks in furnaces may be welded
provided any one crack does not exceed
12 inches in length and after completion
the weld is stress-relieved. Cracks in
corrugated furnaces may be repaired by
welding provided any one crack does
not exceed 20 inches in length.
(e) Fire cracks may be welded at
riveted door openings extending from
the edge of the plate, but not more than
2 inches beyond the centerline of the
rivet holes.
(f) Cracks may be welded between
tube holes in the shell of water tube
boiler drums, provided there are not
more than two cracks in any one row in
any direction, nor more than a total of
four cracks in a drum, and further
provided the welding meets the
requirements of this subchapter for
Class I welded pressure vessels.
(g) Cracks that occur in superheater
manifolds, water wallheaders, water
drums, sectional headers, and other
appurtenances including steam
manifolds of water tube boilers may be
repaired in accordance with paragraph
(h) of this section.
(h) All cracks permitted to be repaired
under this subpart must be excavated to
sound metal by grinding, flame or arc
gouging or chipping out the defective
metal to form a clean welding groove.
Either a V groove or U groove wherein
complete penetration of the weld metal
is secured may be used. After
excavation is completed and prior to
welding, the excavated area must be
examined by magnetic particle, dye
penetrant, or other acceptable test
method. When the reverse side of the
weld is accessible, the root of the weld
must be chipped or ground out to
ensure a clean surface of the originally
deposited metal and the resultant
groove welded to obtain a sound weld
having complete penetration. When the
weld cannot be back chipped because
the reverse side is inaccessible, a
backing strip or other approved means
of assuring full penetration must be
employed.
(i) During welding of cracks, a preheat
must be maintained by controlled
temperatures. The degree of preheat
must be determined by the rules listed
in accordance with the materials Pnumber groupings of PW–38, Section I
of the ASME BPVC, appendix R, Section
VIII of the ASME BPVC, and Appendix
D, Section IX of the ASME BPVC (all
incorporated by reference; see § 59.01–
2). For thicknesses exceeding threefourths inch, suitable U grooves should
be employed. A welding sequence must
be used so as to equalize welding
stresses.
(j) Postweld heat treatment of repaired
cracks must be performed in accordance
PO 00000
Frm 00128

with the rules specified in PW–39,
Section I of the ASME BPVC and UW–
40, Section VIII of the ASME BPVC for
boilers and pressure vessels
respectively.
(k) Welded repairs of cracks must be
nondestructively tested in accordance
with the rules specified in PW–40,
Section I of the ASME BPVC, and UW–
51, Section VIII of the ASME BPVC for
boilers and pressure vessels
respectively.
(l) After cracks originating in tube or
rivet holes are repaired by welding, the
holes must be properly reamed and the
weld reinforcing ground flush with the
plate in way of rivet heads.
(m) Flat tube sheets in fire-tube
boilers which have corroded or where
cracks exist in the ligaments may be
repaired by welding.
(n) Welding repairs to drums of power
boilers, except as otherwise permitted in
this subpart, are prohibited.
§ 59.10–10
Corroded surfaces.
(a) Corroded surfaces in the calking
edges of circumferential seams may be
built up by welding to the original
thickness under the following
conditions:
(1) The thickness of the original metal
to be built up between the rivet holes
and the calking edge must not be less
than one-fourth of the diameter of the
rivet hole, and the portion of the calking
edge to be thus reinforced must not
exceed 30 inches in length in a
circumferential direction.
(2) In all repairs to circumferential
seams by welding, the rivets must be
removed over the portions to be welded
for a distance of at least 6 inches beyond
the repaired portion.
(3) After repairs are made the rivet
holes must be reamed before the rivets
are redriven.
(b) It is not permissible to build up or
reinforce a grooved or corroded area of
unstayed internal surfaces by means of
welding, except that widely scattered
pit holes may be built up by welding.
(c) Where external corrosion has
reduced the thickness of flat plates
around hand holes to an extent of not
more than 40 percent of the original
thickness and for a distance not
exceeding 2 inches from the edge of the
hole, the plate may be built up by
welding.
(d) Where stayed sheets have
corroded to a depth not exceeding 40
percent of their original thickness, they
may be reinforced or built up by
welding. Where the staybolts are fitted
with riveted heads, the staybolts in the
reinforced area must be renewed, but

reinforcing has been applied; collars
may be welded around the staybolts in
lieu of the nuts. Such reinforced areas
must not exceed 400 square inches nor
more than 30 inches in one direction.
Two such areas in any one plate may be
reinforced provided that the distance
between the reinforced surfaces is not
less than 30 inches.
(e) When the corroded portion of a
staybolted surface exceeds 400 square
inches, it is permissible to make repairs
by cutting out the defective portion and
replacing it with a new plate, the edges
of the new plate to be welded in
position. In such cases, new staybolts
must be fitted, and where welding is
performed through a line of staybolts,
welded collars must be used to attach
the staybolts.
(f) Eroded seams of welded pressure
vessels may be repaired by rewelding
the wasted portion. The wasted section
of the seam must be excavated
sufficiently by grinding, flame or arc
gouging or chipping to ensure proper
weld penetration. Rewelded seams must
be nondestructively tested in
accordance with Section VIII of the
ASME BPVC (incorporated by reference,
see § 59.01–2).
§ 59.10–15
Rivets and staybolts.
(a) It is not permitted to reinforce or
build up by welding the heads of rivets
or staybolts that have deteriorated. Such
rivets or staybolts must be replaced. The
seal welding of rivet heads to secure
tightness is prohibited.
(b) Where leaks develop around
staybolts which are otherwise in good
condition, the nuts may be replaced
with a beveled collar formed around the
end of the stay by means of welding. In
such cases, the depth of collar measured
on the stay and the width measured on
the plate, must be equal to one-half the
diameter of the staybolt.

(a) Unreinforced openings in the
shells or drums of boilers or pressure
vessels may be closed by the use of a
patch or plate inside the drum or shell
and sealed against leakage by welding.
Such plates must have a diameter of at
least 2 inches larger than the diameter
of the hole and must have a thickness
equal to the thickness of the plate to
which it is attached. It is not

permissible to insert such patches in the
shell or head flush with the surrounding
plate unless the requirements of this
subchapter for Class I welded pressure
vessels are met.
(b) Portions of tube sheets which have
deteriorated may be renewed by
replacing the wasted portion with a new
section. The ligaments between the tube
holes may be joined by means of
welding and staytubes.
§ 59.10–25
Stayed areas.
Welding repairs are permitted in
staybolted areas or areas adequately
stayed by other means so that should
failure of the welds occur the stress will
be carried by the stays. The welds must
be located entirely within staybolted
areas and must not pass through the
outer row of stays.
§ 59.10–30
Seal welding.
Where leaks occur in riveted joints or
connections, they must be carefully
investigated to determine the cause.
Such leaks may be made tight by seal
welding the edge, if accepted by the

heads.
Wrapper plates and back
Wrapper plates and back heads may
be renewed in whole or repaired as
follows:
(a) Wrapper plates or back heads must
be cut between two rows of staybolts or
on a line of staybolts where the
thickness is approximately the same as
the original construction. If welding is
employed on a line of staybolts, the
staybolts must be fitted with a welded
collar.
(b) The edges of wrapper plates
riveted to tube sheets and back heads
must be removed by cutting out the
rivets.
(c) The edges of existing plates and
new plates must be beveled by
chipping, flame cutting or grinding so as
to form a suitable groove whereby
complete penetration of the weld metal
will be obtained. The edge preparation
and preheat must comply with the
requirements of § 59.10–5(h).
(d) The edges of the new plate must
be butt-welded, and the plate must be
riveted to the flanges of the tube sheet
and back heads and the staybolts
renewed.
(e) Sections of wrapper plates of
combustion chambers outside of stayed

Repairs
§ 59.15–1
Furnace repairs.
(a) Where corrugated or plain furnaces
or flues are distorted by 1.5 inches or
more, they must be repaired by either of
the following methods:
(1) The furnace must be forced back
to a true circular shape, and the Officer
in Charge, Marine Inspection, may
require strongbacks or other acceptable
means of support to hold the furnace; or
(2) The furnace must be adequately
stayed as determined by the Officer in
Charge, Marine Inspection.
(b) Distortion means the difference
between any single measured diameter
of the furnace and the diameter of a true
circle at the same location.
(c) Where the distortion does not
exceed 1.5 inches it will not be
necessary to force the furnace back to a
true circle if the allowable pressure is
reduced in the ratio of 1.5 percent for
each one-tenth of an inch of distortion.
However, if the maximum distortion
does not exceed 1 inch, the repairs or
reduction in pressure will not be
required unless considered necessary by
the marine inspector.
(d) When it becomes necessary to
rivet a patch to a furnace or other part
of the heating surface, the riveted patch
must be placed on the waterside of the
plate in order not to form a pocket in
which sediment may collect.
(e) Furnace crowns which have
become distorted, not in excess of the
limitations provided in paragraph (c) of
this section, may be repaired by forcing
back the distorted section to as nearly a
true circle as possible and reinforcing
the same by means of a ring, arc- or gaswelded to the distorted corrugation as
shown in figure 1 to § 59.15–1, the
welding to be done by welders and

§ 61.05–1
Scope.
The term boiler as used in this subpart
includes power boilers subject to part 52
of this subchapter and heating boilers
subject to part 53 of this subchapter.
§ 61.05–5 Preparation of boilers for
inspection and test.
(a) For internal inspection, manhole
and handhold plates, and washout plugs
must be removed as required by the
marine inspector and the furnace and
combustion chambers must be
thoroughly cooled and cleaned.
(b) In preparing the boilers for the
hydrostatic test, they must be filled with
water at not less than 70 °F and not
more than 160 °F for watertube boilers,
and not more than 100 °F for firetube
boilers. The safety valves must be
secured by means of gags or clamps.
§ 61.05–10
Boilers in service.
(a) Each boiler, including superheater,
reheater, economizer, auxiliary boiler,
low-pressure heating boiler, and unfired
steam boiler, must be available for
examination by the marine inspector at
intervals specified by table 1 to § 61.05–
10, and more often, if necessary, to
determine that the complete unit is in
a safe and satisfactory condition.
(b) The owner, master, or person in
charge of the vessel must give ample
notice to the cognizant Officer in
Charge, Marine Inspection, so that a
marine inspector may witness the tests
and make the required inspections.
(c) Firetube boilers which cannot be
entered, or which cannot be
satisfactorily examined internally, all
boilers of lap seam construction and all
boilers to which extensive repairs have
been made or the strength of which the
marine inspector has any reason to
question, must be subjected to a
hydrostatic test of 1.5 times the
maximum allowable working pressure.
All other boilers must be subjected to a
hydrostatic test of 1.25 times the
maximum allowable working pressure.
(d) In applying hydrostatic pressure to
boilers, arrangements must be made to
prevent main and auxiliary stop valves
from being simultaneously subjected to
the hydrostatic pressure on one side and
steam pressure on the other side.
(e) If the marine inspector has reason
to believe that the boiler has
deteriorated to any appreciable extent
under the bottom where it rests on
saddles or foundations, they must cause
the boiler to be lifted to such position
50187
that it can be thoroughly examined,
provided the examination cannot be
made otherwise.
(f) The marine inspector may require
any boiler to be drilled or gaged to
determine actual thickness any time its
safety is in doubt. At the first inspection
for certification after a firetube or flue
boiler has been installed for 10 years, it
must be gaged to determine the extent
of deterioration. Thickness will be
measured at or near the waterline, at the
bottom and at such other places deemed
necessary by the marine inspector.
Examination may be by drilling or a
nondestructive means acceptable to the
marine inspector. Prior to the use of a
nondestructive method of examination,
the user must demonstrate to the marine
inspector that results having an
accuracy within plus or minus 5 percent
are consistently obtainable.
(g) If the thickness is found to be less
than the original thickness upon which
the maximum allowable working
pressure (MAWP) was based, the
MAWP must be recalculated. The
thickness of the thinnest measured
portion must be used in this calculation.
Either the design formulas given in this
subchapter or the ones in effect when
the boiler was contracted for or built
may normally be used in this
recalculation. In no case will an
increase in the pressure allowed be
made.

II. Background, Basis, and Purpose
This rule incorporates by reference updated marine engineering
standards in Title 46 of the Code of Federal Regulations (CFR)
subchapter F, including standards for boilers, pressure vessels,
auxiliary machinery, piping, valves, and fittings, for various types of
vessels. The rule also adds a limited number of alternative standards
and eliminates outdated or unnecessarily prescriptive regulations.
The Office of Management and Budget (OMB) directs, via OMB Circular
A-119, that federal agencies use industry-based voluntary consensus
standards in lieu of government-unique requirements, where appropriate.
The Coast Guard actively participates in the development of industry
standards for safety of marine equipment at the International Maritime
Organization (IMO), the International Organization for Standardization
(ISO), ASTM International (ASTM), American Society of Mechanical
Engineers (ASME), and other standards-setting bodies that belong to the
American National Standards Institute (ANSI). Recently published
editions of these standards provide necessary updates to materials,
testing practices, and technologies, enhancing safety and compliance.
The Coast Guard has statutory authority to issue regulations under
Title 43, United States Code (U.S.C.), section 1333(d), 46 U.S.C. 3306
and 3703, and the Department of Homeland Security (DHS) Delegation No.
00170.1, Revision No. 01.3, paragraph (II)(92)(b), which delegates
authority under these statutes to the Commandant of the Coast Guard.
Title 43 of the U.S.C., section 1333(d) grants the Secretary the
authority to promulgate and enforce regulations with respect to lights
and other warning devices, safety equipment, and other matters relating
to the promotion of safety of life and property on artificial islands,
installations, and other devices. Title 46 of the U.S.C., section
3306(a)(1), authorizes the Secretary to prescribe regulations for the
design, construction, alteration, repair, and operation of vessels
subject to inspection, including equipment, appliances, propulsion
machinery, auxiliary machinery, boilers, unfired pressure vessels,
piping, and electric installations. Additionally, 46 U.S.C. 3703(a)
grants the Secretary authority to regulate tank vessels regarding the
construction, alteration, repair, maintenance, operation, and equipping
of vessels that may be necessary for increased protection against
hazards to life and property, for navigation and vessel safety, and for
[[Page 50059]]
enhanced protection of the marine environment.
On October 19, 2021, the Coast Guard published a notice of proposed
rulemaking (NPRM) titled ``Updates to Marine Engineering Standards,''
(86 FR 57896) requesting comments on the proposed changes implemented
by this final rule, including several updates to the standards
incorporated by reference. A detailed description of the background and
proposed changes is available in that NPRM.
III. Discussion of Comments
During the 60-day comment period for the NPRM, beginning on October
19, 2021, the Coast Guard received a comment requesting an extension of
the comment period. The Coast Guard granted this request, and, on
December 20, 2021, published an extension of the comment period (86 FR
71864), for 45 days, until February 3, 2022. During the extended
comment period, we received two comments. The comments can be viewed in
the docket following the instructions in the ADDRESSES section of this
preamble. We summarize the comments and our responses in the following
sections, starting with general comments then moving to specific
comments.
A. General Comments on the Proposed Rule
We received two comments supporting \1\ the update of many of the
standards proposed for incorporation by reference (IBR) in subchapter
F, emphasizing the importance of ``referencing the latest editions of
widely used consensus standards.'' Both comments also supported the
addition of alternative standards and the elimination of outdated or
unnecessarily prescriptive regulations. We thank the commenters for
their support of this update to subchapter F.
---------------------------------------------------------------------------
\1\ One commenter provided a lengthy statement detailing its
full support of the proposed updates, while the other commenter
endorsed the first commenter's statement. When we use ``both
comments'' we mean either both comments explicitly, or the first
comment as supported by the second.
---------------------------------------------------------------------------
B. Editorial Comments on the Proposed Rule
Comment: Two commenters recommended that, for the sake of clarity,
proposed 46 CFR 56.60-1(a)(2) be turned into a multiple-paragraph list.
The same commenters stated that the reference to table 56.60-1(b) in
Sec. 56.60-1(b) appears erroneous and should probably refer to table 2
to Sec. 56.60-1.
Response: We agree and have reorganized Sec. 56.60-1(a)(2) so that
it now constitutes new Sec. 56.60-1(a)(2) through (4). We have revised
the table reference in Sec. 56.60-1(b) to conform with other updates
to table numbering as proposed in the NPRM.
C. Substantive Comments on Standards Within the Proposed Rule
Comment: Two commenters recommended that the Coast Guard continue
the IBR of ASME B16.10, Face-to-Face and End-to-End Dimensions of
Valves, which we proposed to remove in the NPRM.
Response: Because ASME B16.10 is already referenced in ASTM F1155,
which we proposed for IBR in the NPRM, in practice ASME B16.10 will
continue to be incorporated by reference even if it is not specifically
mentioned. Specifically incorporating ASME B16.10 is redundant when the
standard and its requirements are provided within ASTM F1155.
Comment: Two commenters recommended the following standards be
incorporated by reference in Part 56:
American Petroleum Institute (API) standard API Spec 6D,
Specification for Pipeline and Piping Valves, 25th Edition;
ASTM B148-18, Standard Specification for Aluminum-Bronze
Sand Castings; and
ASTM D2996-17, Standard Specification for Filament-Wound
``Fiberglass'' (Glass-Fiber-Reinforced Thermosetting-Resin) Pipe.
Response: Because ASTM D2996 is already referenced within ASTM
F1155, which we incorporate by reference by means of this final rule,
it is not necessary to duplicate the reference. With regards to ASTM
B148 and API Spec 6D, these standards are neither currently referenced
within subchapter F, nor were they proposed for IBR in the NPRM. We
recognize that there are numerous national and international standards
that provide similar requirements and equivalent performance for the
same equipment or system. Naval architects and system designers may
submit for approval components designed to alternative standards that
provide an equivalent level of safety in accordance with the provisions
of 46 CFR 50.20-30.
Comment: We received two comments recommending against
incorporating by reference API Recommended Practice 14C, Analysis,
Design, Installation, and Testing of Safety Systems for Offshore
Production Facilities, Eighth Edition, February 2017 (which would
update the current incorporation by reference within subchapter F of an
earlier edition of this standard), and API STD 53, Well Control
Equipment Systems for Drilling Wells, 5th Edition (which would replace
a superseded standard currently incorporated by reference within
subchapter F). The commenters expressed concern that, since the June 4,
2013, Memorandum of Agreement between the Coast Guard and the Bureau of
Safety and Environmental Enforcement (BSEE) designates BSEE as the lead
agency for safety and operations on outer continental shelf (OCS)
facilities, and the referenced standards are already included in BSEE
regulations, including them in subchapter F as well could create a risk
of edition conflict between BSEE and the Coast Guard. For the same
reason, the commenter recommended removing the entirety of subpart
58.60--Industrial Systems and Components on Mobile Offshore Drilling
Units (MODUs), and using the standards incorporated by reference in 30
CFR 250.198 for industrial systems and components as well as marine
systems and components for all oil and gas facilities on the OCS.
Response: We have elected to retain these standards in subchapter F
and not remove subpart 58.60 from the CFR, in order to maintain clarity
regarding requirements for engineering systems. The ship and facility
marine engineering and electrical systems that the Coast Guard
regulates interface with industrial systems under the jurisdiction of
BSEE. The Coast Guard and BSEE have a shared mission of ensuring safety
on the OCS. We work together closely to ensure our requirements are not
in conflict.
Comment: We received a comment regarding the IBR of the American
Bureau of Shipping (ABS) standard, ABS Rules for Building and Classing
Marine Vessels, 2020, Part 4, Vessel Systems and Machinery, which we
proposed in the NPRM as an update of the earlier 2003 standard already
incorporated in subchapter F. The commenter argued that ``incorporating
the classification rules of [ABS] in subchapter F (and 46 CFR Chapter
I) uses the rules of one classification society to set a regulatory
baseline, which could competitively disadvantage other societies and
deprive the industry of knowledge and innovation available in other
societies' rules.''
Response: We appreciate the comment, but do not agree. Many vessels
normally subject to the regulations of subchapter F are enrolled in the
Alternate Compliance Program (ACP), where the rules of any recognized
classification society may be used in lieu of the requirements of
subchapter F. Given that the rules of other recognized classification
societies are already in wide use through the ACP
[[Page 50060]]
and will remain so, the IBR of the ABS standards will not disadvantage
other classification societies or interfere with the sharing of
expertise throughout the industry. We discussed this in depth in
``Discussion of Proposed Rule'' in the NPRM.\2\
---------------------------------------------------------------------------
\2\ 86 FR 57896, 57897.
---------------------------------------------------------------------------
D. Comments Recommending Additional Regulatory Action
Comment: Two commenters recommended updating 33 CFR subchapter N to
clarify the applicability of the rule to existing and new floating OCS
facilities, nearly all of which are not, properly speaking, ``vessels''
or ``ships.'' The commenters also recommended that the Coast Guard act
on the March 28, 2018, National Offshore Safety Advisory Committee
(NOSAC) Production Subcommittee Final Report on [U.S. Coast Guard]
Regulatory Reform recommendation that ``The Coast Guard should issue
NOSAC a new Task Statement to evaluate the suitability of the
regulations in 46 CFR Subchapter F (Marine Engineering) and 46 CFR
Subchapter J (Electrical Engineering) to floating OCS facilities.'' \3\
The commenters suggested that, since floating OCS facilities are not,
properly speaking, ``vessels'' or ``ships,'' the application of
subchapter F to such facilities has led to multiple requests for
equivalencies and alternatives, and that while the Coast Guard has
attempted to address this via policy letter,\4\ this policy letter only
applies to floating OCS facilities classed with a classification
society.

---------------------------------------------------------------------------
The commenters suggested that, at a minimum, the Coast Guard should
update 33 CFR 143.120 to establish the date on which this rule would
apply to a new floating OCS facility.
Response: An update to 33 CFR subchapter N regarding its
applicability to floating OCS facilities and a statement on the same
issue to NOSAC are outside the scope of this rulemaking but could be
addressed in a future rulemaking. We encourage questions regarding the
applicable regulations for floating OCS facilities to be sent either to
the Coast Guard's Eighth District Outer Continental Shelf Division
Staff (website: https://www.atlanticarea.uscg.mil/D8/OCS) or the Outer
Continental Shelf National Center of Expertise (OCSNCOE) (website:
https://www.dco.uscg.mil/OCSNCOE). As to an update to 33 CFR 143.120,
the date that 33 CFR subchapter N requires compliance with subchapter F
is the effective date, 90 days after the publication of this final
rule.
E. Comments Recommending Additional Non-Regulatory Action
Comment: Two commenters supported the proposed IBR of ASTM F1155-10
(Reapproved 2015), Standard Practice for Selection and Application of
Piping System Materials, but also recommended the Coast Guard's Marine
Safety Center (MSC) cancel Marine Safety Center Technical Note (MTN)
02-10, Material Selection for Vital Piping Systems, as superseded by
the adoption of this standard.
Response: We generally agree, but we note that ASTM F1155 has
application to all shipboard piping systems, while MTN 02-10 is focused
on ``vital'' shipboard systems. MTN 02-10 will be reviewed and revised
if necessary.
F. Comments on the Regulatory Analysis (RA)
Comment: Two comments expressed concern that table 3 of the RA did
not specifically address floating OCS facilities and did not provide
enough clarity to determine if floating OCS facilities were included
within the table. The commenters recommended that the Coast Guard
undertake changes to the Marine Information for Safety and Law
Enforcement (MISLE) system and its internal documentation to eliminate
any confusion regarding the inclusion or exclusion of floating OCS
facilities, not only for the purpose of this rule but also for future
Coast Guard regulatory actions.
Response: We agree with these comments. In our MISLE database,
floating production systems are listed as being inspected under 46 CFR
subchapter I-A; this is incorrect, and, as a result, we overstated the
number of MODUs in the RA, which lowered the population of vessels in
the ``Industrial Vessel'' category. After further analysis we revised
the population of MODUs to one, because we incorrectly classified the
remainder based on the subchapter inspection field in MISLE. The Coast
Guard will amend its MISLE database to correctly label these vessels.
While we did update table 4 of the RA in response to public
comments, we did not receive feedback from the public that would impact
our estimate of the number of equivalency requests that are submitted
to the Coast Guard on an annual basis. Therefore, the regulatory
assessment of costs, cost savings, and benefits of the NPRM remain
unchanged, other than the use of more current economic data, where
available.
Comment: We also received two related comments regarding the number
of specific vessel types, suggesting that the listing of 110 MODUs in
table 3 of the RA was not accurate and that there are fewer than 5
U.S.-flagged MODUs in active service.
Response: We agree with these comments. As stated above, in the RA
for the proposed rule, we incorrectly labeled ``floating production
systems'' and counted them as MODUs. This overstated the number of
MODUs because these systems are incorrectly listed in MISLE as being
inspected under title 46 CFR subchapter I-A. After further analysis, we
revised the population of MODUs for the final rule to one, because we
incorrectly classified the rest based on the subchapter inspection
field in MISLE. Floating production systems are facilities certificated
and inspected under 33 CFR subchapter N and not vessels inspected under
46 CFR subchapter I. We overestimated the number of affected vessels in
the proposed rule; therefore, in this final rule we revise the number
of vessels in the subchapter I from 6,086 down to 623. Because we
updated the entire population for this final rule, the total number of
vessels and facilities is revised down from 16,148 in the proposed rule
to 5,655 (see table 4 in this document).
IV. Discussion of Rule
A. General Discussion
In order to decrease the likelihood of introducing errors, to
improve efficiency during the publication process, and to meet drafting
and formatting requirements for publication, we are revising or
revising and republishing entire sections, subparts, and parts, as
appropriate. Except as explained as a change in this preamble, the
individual (piecemeal) changes are detailed in the proposed rule,
published on October 19, 2021 (86 FR 57896).
In general, the rule makes the following changes:
1. Corrections--we amend several sections to correct inadvertent
errors or deletions. We also remove material that is obsolete or
superfluous, and update contact information for Coast Guard offices and
standards organizations.
2. Stylistic Revisions--we revise the language of some sections,
primarily for greater clarity. This includes revising sentences
containing the word ``shall'' to use ``must'' or another grammatically
equivalent word or phrase in accordance with plain language guidelines.
We also standardize terms
[[Page 50061]]
that were variously presented as compound words, hyphenated
constructions, or multi-word phrases using the format preferred by the
Government Publishing Office.
3. Updated cross references--we update cross references to reflect
the relocation within the CFR of pertinent provisions. We also
standardize designations for tables, figures, notes, and formulas using
the format preferred by the Office of the Federal Register (OFR).
4. Updated industry standards--we update cross-references to
industry standards by adding new references, replacing references to
superseded standards or editions, and by conforming text accordingly.
We incorporate these updated standards because they reflect the latest
available technologies, practices, and procedures that are recommended
by consensus bodies, ship classification societies, and other maritime
organizations with experience in the industry. As the baseline upon
which other standards, rules, and equivalency requests are evaluated,
it is important that subchapter F incorporate up-to-date references.
The class rules of ABS, in particular, are incorporated by reference in
multiple locations within subchapter F and 46 CFR chapter I.
It is important to note that, while these rules set the regulatory
baseline or standard for specific engineering systems and equipment,
the Coast Guard has also authorized classification societies in
accordance with 46 CFR part 8. These authorized classification
societies are listed on the Coast Guard website \5\ and have been
delegated the authority to perform certain functions and certifications
using their respective class rules for vessels enrolled in the ACP. For
vessels not enrolled in the ACP, the class rules of an authorized
classification society may be proposed as an alternative to the ABS
class rules incorporated by reference for engineering systems and
equipment. Table 1 indicates the sections we amend, and why.

B. Standards Incorporated by Reference To Be Updated or Added
Following this paragraph, we include an alphabetical list of the
standards we are updating or adding, each with a listing of the
sections in which they appear in 46 CFR. For each standard listed, we
describe the topics covered by the standard, the changes to the
standard, any difference between the older edition of standards
currently included within the CFR via IBR and the edition adopted, and
a list of subparts or sections that reference the standard.
ABS Rules for Building and Classing Marine Vessels, Part
4, Vessel Systems and Machinery, January 2020. This standard updates
the 2003 standard, incorporated by reference in Sec. Sec. 58.01-5,
58.05-1, 58.10-15, 58.20-5, 58.25-5, 62.25-30, 62.35-5, 62.35-35,
62.35-40, 62.35-50, and 62.50-30. In 2020, ABS changed the name of the
Steel Vessel Rules to Marine Vessel Rules. All parts and sections
contain the same information along with updates to reflect the current
technologies for commercial vessels. The rules contain a comprehensive
set of construction and maintenance requirements for ships and offshore
facilities.
ABYC P-1-14, Installation of Exhaust Systems for
Propulsion and Auxiliary Engines, reaffirmed 2014. This American Boat
and Yacht Council (ABYC) standard updates the 1973 standard,
incorporated by reference at Sec. 58.10-5. It contains the rules and
guidance for the safe installation and operation of exhaust systems for
propulsion and auxiliary engines. Updates to the standard are editorial
(non-substantive) in nature.
ANSI Z21.22-2015, Relief valves for hot water supply
systems, July 2015. This standard updates the 1986 edition incorporated
by reference at Sec. 63.25-3. This standard establishes requirements
for relief valves for hot water systems. It has been regularly revised
to accommodate technological developments, to address administrative
requirements, to incorporate interpretations, and to clarify the
standard intent. It is the internationally accepted standard.
API RP 14C, Analysis, Design, Installation, and Testing of
Safety Systems for Offshore Production Facilities, Eighth Edition,
February 2017 with errata 1 May 2018. This standard updates the 1986
edition incorporated by reference in Sec. 58.60-9. This document
presents provisions for designing, installing, and testing both process
safety and non-marine emergency support systems on an offshore
production facility. The updates made to the standard are editorial in
nature.
API STD 53, Well Control Equipment Systems for Drilling
Wells, Fifth Edition, December 2018. This standard replaces API
Recommended Practice 53 (API RP 53), the second edition of which is
currently incorporated by reference at Sec. 58.60-7. API STD 53
promotes best safety practices for the oil and gas industry during
drilling operations, principally focusing on blowout prevention.
API STD 607, Fire Test for Quarter-turn Valves and Valves
Equipped with Nonmetallic Seats, Seventh Edition, June 2016. This
standard replaces the fourth edition of API STD 607 (1993),
incorporated by reference at Sec. 56.20-15. This standard specifies
fire type-testing of valves that contain nonmetallic materials and
pressure-containing capabilities after the fire test.

Updating incorrect CFR reference.
Section 58.16-10 Approvals.
Deleting the requirement in paragraph (a) that gas-consuming
appliances be ``of a type approved'' by the Commandant. The requirement
that the Commandant specifically ``approve'' all types of gas-consuming
appliances is not necessary, since the Coast Guard verifies during plan
review that appliances are tested and listed by third-party
laboratories and meet the additional requirements of Subpart 58.16.
Changing the word ``approved'' to ``accepted'' in paragraph (c).
Because this paragraph refers to another government agency's
requirements for safety-relief devices, and shipboard appliance
installations are reviewed case by case, ``acceptance'' allows for more
flexibility than ``approval'' when evaluating the overall installation
for compliance.
Section 58.16-30 Operating instructions.
Updating paragraph (k) to make the text easier to read without
impacting the public.
Section 58.16-35 Markings.

as unenforceable.
Deleting paragraph (g) as this paragraph is applicable only to tank
vessels of 40,000 gross tons or more constructed before 1984. Virtually
all those vessels have been phased out of service due to the pollution
prevention requirements in 33 CFR 157 for ``double hulls'' on tank
vessels.
Section 58.30-1 Scope.
Deleting certain text in paragraph (a) as not applicable.
Section 58.30-5 Design requirements.

Modifying paragraph (b) to update the name, telephone number, and
web address of ASTM International.
Section 61.05-10 Boilers in service.
Eliminating unnecessary and outdated text regarding boiler
inspections from paragraphs (a) and (f).
Section 61.10-5 Pressure vessels in service.
Modifying paragraph (g) to provide inspection compliance options,
in lieu of the hydrostatic test currently required by this paragraph,
for bulk storage tanks containing refrigerated liquefied carbon dioxide
for use aboard a vessel as a fire-extinguishing agent. The inspection
options consist of performing a hydrostatic test or having an internal
inspection. This is further explained in the regulatory language.

Section 62.35-20 Oil-fired main boilers.
Removing an outdated Note to paragraph (d)(1).
Section 62.35-50 Tabulated monitoring and safety control
requirements for specific systems.
Deleting the requirements for main propulsion boiler supply casing
and uptakes, burner flames, control power, and burner valves in Table
62.35-50. These components are required to comply with the same
requirements in Section 4-9-6 of the ABS Marine Vessel Rules (2020),
which is referenced in this table.
Modifying the requirements for ship service generators in Table
62.35-50. Currently, compliance with the ABS Steel Vessel Rules for
propulsion boilers and propulsion diesel engines is required. The
requirements for auxiliary generators in Section 4-9-6 of the ABS
Marine Vessel Rules (2020) are referenced instead because this section
of the ABS Rules is more directly applicable to generators.
Deleting the requirements for generators to comply with Sec. Sec.
111.12-1 (b) and (c), and parenthetical items 6 and 7 in Table 62.35-
50.
Part 63--Automatic Auxiliary Boilers

Boiler Pressure Vessel Code. Making stylistic changes throughout part
64 for greater clarity and readability.
Section 64.2 Incorporation by reference.
Modifying paragraph (b) to update the address for the ASME.
E. Additional Changes From the NPRM
In addition to the changes discussed above, we are making further
editorial changes from the text proposed in the NPRM, as follows.
In Sec. 56.30-20(d), correcting an erroneous Fahrenheit to Celsius
conversion. The Fahrenheit temperature currently provided in the CFR is
correct.
In Sec. 56.50-60(n), restoring the word ``flammable,'' as it was
inadvertently deleted.
In Sec. 56.50-70(e), clarifying that the openings indicated in
this paragraph are openings for fuel tanks.
In Sec. 56.50-75(b)(1), adding ``seamless steel'' to the list of
acceptable materials. Seamless steel has always been acceptable under
this paragraph as an ``other material,'' but, because it is commonly
used, we are adding it to the list for clarity.
In Sec. 56.50-75(b)(6), removing the words ``on vessels less than
100 gross tons and tank barges'' as unnecessary because this
applicability condition is already specified in Sec. 56.50-75(b).
In Sec. 56.50-95(f), removing redundant text relating to
prohibitions on the use of heat-sensitive materials.
In Table 2 to Sec. 56.50-105, removing footnote 2 and renumbering
the remaining footnotes. Footnote 2 redirected readers to part 54 for
additional information, and all the necessary information is found in
the table. Deleting cross-references to table 1 to Sec. 56.85-10(c) as
we are removing that table, as discussed below.
In Sec. 56.60-1, relocating note 1 to table 1 to Sec. 56.60-1(a)
to follow the table rather than precede it and redesignating the other
note as note 2 to table 1 to Sec. 56.60-1(a).
Reorganizing the information in table 1 to Sec. 56.60-2 and its
associated footnotes to ensure all substantive requirements are found
in the table itself and renumbering the remaining footnotes.
In Sec. 56.85-10, revising the text and removing table 1 to Sec.
56.85-10(c) to simplify the information presented and focus on the
incorporated standard, ASME B31.1. The relevant information regarding
heat treatment of welds is already provided by ASME B31.1 and it is
unnecessary to supplement the text with additional Coast Guard
requirements that are redundant to ASME B31.1. In addition, removing a
cross-reference to table 1 to Sec. 56.85-10(c) in Sec. 56.50-105, as
noted above.
As with Sec. 56.85-10, revising the text in Sec. 56.85-15 to
remove unnecessary supplementary information regarding post-heat
treatment of welds and, instead, directing readers to follow the
relevant section and table of the incorporated standard, ASME B31.1.
In Sec. 56.95-10 (a)(1), correcting an Imperial unit/Metric system
unit conversion that is incorrect in the current CFR.
In Sec. 58.05-1(b), removing the requirement for drawings to be
submitted in quadruplicate because drawings are typically submitted
under this section electronically, making multiple copies unnecessary.
In Sec. 58.16-10(e), removing the requirement for plans to be
submitted in triplicate because plans are typically submitted under
this section electronically, making multiple copies unnecessary.
Restoring Sec. 58.25-25(a) and (e), with minor stylistic changes,
as these paragraphs were inadvertently deleted.
In Sec. 58.50-1(b), removing the text ``converted on or after July
1, 1935'' because the emergency systems requirements under this section
now apply to all ships.
Reorganizing the information in table 1 to Sec. 62.35-50 and its
associated footnotes to ensure all substantive requirements are in the
table itself and renumbering the remaining footnotes.
In Sec. 62.50-20(g)(2), correcting a drafting error by changing
the reference to ``Sec. Sec. 111.12-11(g) and 111.30-1 of this
subchapter'' to read ``Sec. Sec. 111.12-11(g) and 111.30-1 of this
chapter.'' The referenced sections are in the same chapter as Sec.
62.50-20(g)(2), but not the same subchapter.
In Sec. 64.2, removing the incorporation by reference of section
VIII of the ASME BPVC, 1974 edition, as it is only relevant as the
source for a constant used in a calculation in Sec. 64.63. The actual
value of the constant, given in that section, is sufficient for the
calculation.
In Sec. 64.63, removing the reference to the 1974 edition of
section VIII of the ASME BPVC as the source of the value of constant C
used in calculating total emergency venting capacity. The source of
constant C is not required for this calculation, and as noted above we
are removing the incorporation by reference
[[Page 50079]]
of section VIII of the ASME BPVC for this part.
V. Incorporation by Reference
Material for incorporation by reference appears in 46 CFR parts 50,
52, 53, 54, 56, 57, 58, 59, 61, 62, 63, and 64 and is summarized in
section IV.B of this preamble. Copies of the material are available
either at the publisher's web address listed in the incorporation by
reference sections in 46 CFR parts 50, 52, 53, 54, 56, 57, 58, 59, 61,
62, 63, and 64 or by contacting the publisher listed for those
standards. We reviewed and updated all the publisher's web addresses
listed in the parts to ensure they are current. You may also contact
the person in the FOR FURTHER INFORMATION CONTACT section for
additional direction on how to obtain access to electronic copies of
the materials.
Based on the volume of equivalency requests the Coast Guard
receives asking us to confirm that the latest edition is equivalent to
or better than the edition currently incorporated, we believe industry
already has access to and uses these more recent standards. The
affected industry typically obtains the more recent editions of
standards in the course of their business in order to address
advancements in technology.
The Director of the Federal Register approved the material in 46
CFR parts 50, 52, 53, 54, 56, 57, 58, 59, 61, 62, and 63 for
incorporation by reference under 5 U.S.C. 552 and 1 CFR part 51.
VI. Regulatory Analyses
We developed this rule after considering numerous statutes and
Executive Orders related to rulemaking. A summary of our analyses based
on these statutes or Executive Orders follows.
A. Regulatory Planning and Review
Executive Orders 12866 (Regulatory Planning and Review), as amended
by Executive Order 14094 (Modernizing Regulatory Review) and 13563
(Improving Regulation and Regulatory Review) direct agencies to assess
the costs and benefits of available regulatory alternatives and, if
regulation is necessary, to select regulatory approaches that maximize
net benefits (including potential economic, environmental, public
health and safety effects, distributive impacts, and equity). Executive
Order 13563 emphasizes the importance of quantifying costs and
benefits, reducing costs, harmonizing rules, and promoting flexibility.
As OMB has not designated this rule a significant regulatory action
under section 3(f) of Executive Order 12866, as amended by Executive
Order 14094, it has not reviewed this regulatory action. An RA follows.
The Coast Guard received four public comments on the affected
population in the RA for the proposed rule. Two of these comments
stated that the RA in the NPRM did not provide clarity on the inclusion
of OCS facilities. We also received two comments, with essentially the
same content, stating that the suggested listing of 110 MODUs in table
3 of the RA in the NPRM was incorrect. We discuss our responses to
these comments in section III.F of the preamble of this final rule. We
are incorporating the commenters' suggestions into the RA for this
final rule and are revising the population of MODUs and Cargo and
Miscellaneous Vessels based on MISLE Data.
We are also revising our affected population estimate from 16,148
vessels and facilities to 5,655. While preparing this final rule we
obtained the most current data from the MISLE database, and determined
we likely overcounted in our analysis in the NPRM (see Affected
Population section for details).\6\ Additionally, we updated the mean
hourly wage rate for private sector workers and Coast Guard military
and civilian personnel using 2022 data. Furthermore, we updated the
load factor used to account for non-wage benefits for private sector
employees by using Q4 2022 U.S. Department of Labor's Bureau of Labor
Statistics (BLS) data instead of Q4 2020 BLS data. We further revised
the load factor for civilian Coast Guard marine engineers from 1.75 to
1.69 to be consistent with other recently published rulemakings from
the Coast Guard's Office of Design and Engineering Standards (CG-ENG).
We present a summary of changes to the RA from the NPRM to the final
rule in table 2, below.
---------------------------------------------------------------------------
\6\ The updated affected population estimate of 5,655 vessels
and facilities subject to subchapter F is similar to the estimate
from the Update to Electrical Engineering Regulations (Subchapter J)
final rule published on March 16, 2023. There is a high degree of
overlap in the populations of vessels and facilities subject to
subchapters F and J; therefore, we believe this revised estimate is
more accurate than what we presented in the NPRM. Readers can access
the Subchapter J final rule at www.federalregister.gov/documents/2023/03/16/2023-04370/update-to-electrical-engineering-regulations.

With this final rule, the Coast Guard updates 46 CFR subchapter F.
This final rule aligns the standards for U.S.-flagged vessels and
facilities in subchapter F with current industry practices to ensure
that regulatory requirements are consistent with current industry
standards. Most of the updates simply incorporate by reference the more
recent versions of the same standards with little or no substantive
change. In some cases, the more recent editions reflect more modern
technologies, terminology, and practices. The updates also correct
regulatory language and remove redundant and outdated references. The
Coast Guard finds no additional costs associated with this rule and
estimates this rule saves the regulated public and the Federal
Government approximately $9.762 million over the 10-year period of
analysis, discounted at 7 percent and in 2022 dollars. The total
annualized cost savings are an estimated $1.390 million, discounted at
7 percent and in 2022 dollars.
The following RA provides an evaluation of the economic impacts
associated with this final rule. Table 3 provides a summary of the
rule's costs and benefits.

------------------------------------------------------------------------
The objective of the final rule is to update design standards in 46
CFR subchapter F by incorporating by reference more recent industry
standards. The final rule provides clarity, simplifies regulatory
compliance for industry with the removal of obsolete regulations, and
revises current regulatory text, which includes the correction of
errors.\8\
---------------------------------------------------------------------------
\7\ The rule continues the Coast Guard's response to the
Presidential Regulatory Reform Initiative of March 4, 1995, and
directives including Executive Orders 12866 and 13563 that are
intended to improve regulation and the regulatory process. The
provisions of this rule remove outdated regulations, revise current
regulatory text, and incorporate by reference more recent national
and international industry standards into the CFR. The Coast Guard
recognizes the significant technological advances technology and
equipment which is used or carried on vessels. As a result, this
rule encourages the use of newer equipment and promotes adherence to
modern standards in the industry.
\8\ We present a full list of corrections in table 1 of the
preamble.
---------------------------------------------------------------------------
Affected Population
The Coast Guard analyzed the impacts of the final rule to determine
the affected population and how the rule affects vessel and facility
owners and manufacturers. The engineering updates for subchapter F
potentially affect the vessels and facilities inspected under the
following subchapters: D ``Tank Vessels;'' H ``Passenger Vessels;'' I
``Cargo and Miscellaneous Vessels;'' I-A ``Mobile Offshore Drilling
Units;'' L ``Offshore Supply Vessels;'' O ``Certain Bulk Dangerous
Cargoes;'' O-I ``Combination Bulk Cargo;'' O-D ``Combination Bulk
Cargo-including chemicals;'' R ``Nautical Schools;'' U ``Oceanographic
Research Vessels;'' and 41 floating production systems (facilities) in
33 CFR subchapter N ``Outer Continental Shelf Activities.'' \9\ Because
the rule impacts only new vessels or those undergoing major
conversions, we estimate that fewer than 200 vessels will be impacted
annually.\10\
---------------------------------------------------------------------------
\9\ We excluded public vessels from the population.
\10\ Based on input from Coast Guard subject matter experts with
relevant technical expertise in the Office of Design and Engineering
Standards (CG-ENG).
---------------------------------------------------------------------------
We estimate the final rule affects about 5,614 vessels and 41
facilities owned by approximately 952 owners and operators. The rule
directly impacts vessel owners or operators procuring a new vessel or
engaging in a major conversion of an existing vessel under conditions
specified in the rule. Large self-propelled vessels generally have a
greater number of complex engineering systems covered in subchapter F
than smaller vessels or barges. With the updates to engineering
standards in this final rule, we expect, therefore, that large self-
propelled vessels are more likely to be impacted.
In the NPRM for this rulemaking, we significantly overcounted the
number of vessels subject to subchapter F because two categories of
vessels in MISLE that do not have distinct 46 CFR subchapters,
``industrial vessels'' and ``tank barges,'' were incorrectly assumed to
be subject to subchapter F's marine engineering requirements in all
cases. Subchapter F is generally applicable only to larger vessels such
as cargo ships, large passenger vessels, and tank vessels, so many
vessels in the categories mentioned above are not subject to its
requirements. In addition, because cargo and tank barges are not self-
propelled, and subchapter F primarily focuses on vital engineering
systems such as propulsion and steering systems, much of subchapter F
is not applicable to barges.
In this final rule we revise the population estimate, as shown in
table 4 below. The total affected population of vessels and facilities
is reduced from 16,148 in the proposed rule to 5,655 in the final rule.
However, vessels are generally subject to the regulations in effect at
the time of ship construction. Therefore, only vessels constructed
subsequent to the effective date of this final rule will be subject to
its requirements, so our estimate of the average number of new vessels
entering service annually (provided in the last row of table 4)
provides a much more realistic picture of the affected population of
this final rule than does the total universe of vessels subject to
subchapter F.

Note: These data are based on Coast Guard data found in the MISLE
database as of September 9, 2022.
The rule also affects businesses involved in vessel or facility
manufacturing. There are approximately 83 shipyards and manufacturers
of vessels or vessel components in the affected population. However,
the Coast Guard believes that because equipment and vessel
manufacturers participate in the development and revision of marine
industry standards and ship design requirements, manufacturers are
already in voluntary compliance with the changes. In addition, the rule
affects the Coast Guard and its staff in the MSC and CG-ENG. The rule
impacts an estimated six civilian engineers and six military engineers.
Summary of Changes Adopted for the Final Rule
In this final rule, the Coast Guard adopts the changes included in
the NPRM, which update the codified references to standards
incorporated by reference in subchapter F with their more recent
editions. More specifically, the changes in the final rule fall into
three categories: (1) editorial changes to the CFR, (2) technical
updates to standards incorporated by reference, and (3) compliance
alternatives to standards incorporated by reference. Based on data from
industry, the Coast Guard assumes industry already uses the more recent
standards referenced in the rule.
First, this final rule makes editorial changes to 46 CFR subchapter
F (parts 50, 52, 53, 54, 56, 57, 58, 59, 61, 62, 63 and 64) that
include such items as the removal of outdated terminology and the
consolidation of text. These changes have no costs or cost savings
associated with them.
Second, this rule updates standards incorporated by reference
throughout subchapter F. Because no resources are required, and because
they have already been adopted voluntarily by manufacturers, these
changes have no cost associated with them.
Third, this rule amends the regulatory text in 46 CFR 58.10-5(d)(1)
and 61.10-5(g) impacting compliance alternatives for vessel and
facility owners or operators. The changes reflect the addition of one
compliance alternative and the removal of another. This change results
from the discontinuation of a standard incorporated by reference that
is the basis of the compliance alternative. (Please see Section IV.D.
in the preamble under the discussion, ``Part 61--Periodic Tests and
Inspections,'' and further details in the ``Cost Savings'' portion of
this RA.) These changes provide regulatory flexibility for the
regulated public. The final rule imposes no additional costs on
industry, and the addition of a compliance alternative in Sec. 61.10-
5(g) may save the regulated public money and generate cost savings for
vessel and facility owners or operators if they choose to use this
compliance alternative.
The final rule promotes consistency between Coast Guard regulations
and national and international standards through incorporation by
reference, provides options with alternative standards, eliminates
obsolete standards, and clarifies the existing requirements through the
changes in 46 CFR subchapter F. Readers may consult the preamble of
this rule for a general summary of the changes.
The final rule adopts the regulatory changes in the proposed rule.
Additionally, based on feedback from the public during the comment
period, the rule reorganizes 46 CFR 56.60-1(a)(2) and adds 46 CFR
56.60-1(b) for the purpose of regulatory clarity. These changes are
editorial in nature and do not impose costs on or create cost savings
for industry.
Data Input for Calculations
This RA uses multiple data sources. We estimated the duration of
tasks and determined the relevant personnel with input from Coast Guard
subject matter experts within CG-ENG.
The Coast Guard obtained wage data from three publicly available
sources. First, for Coast Guard military personnel, we used the Coast
Guard Commandant Instruction entitled ``Reimbursable Standard Rates''
(commonly called Commandant Instruction W).\11\ Second, for Coast Guard
civilian personnel we used OPM's GS hourly rates for the Washington,
DC, locality pay area for 2022.\12\ Third, for workers outside of the
Federal Government, we used the BLS Occupational Employment and Wage
Statistics dataset for 2022 for private sector wage rates.
---------------------------------------------------------------------------
\11\ The Instruction is dated August 11, 2022, and is numbered
COMDTINST 7310.1W. Appendix B of COMDINST 7310.1W lists the relevant
data; please see in-government wage data. The file is available at
https://media.defense.gov/2022/Aug/24/2003063079/-1/-1/0/CI_7310_1W.PDF (last visited September 28, 2022). Commandant
Instruction W provides fully loaded wage rates for military
personnel.
\12\ The Coast Guard obtained hourly wage rates from OPM's
salary table for 2022 for the Washington, DC, locality, which
readers can access at https://www.opm.gov/policy-data-oversight/pay-leave/salaries-wages/salary-tables/pdf/2022/DCB_h.pdf (last visited
May 12, 2023). For Coast Guard civilian personnel, we use the hourly
wage rates that correspond to a step 5 wage rate for the appropriate
GS grade.
---------------------------------------------------------------------------
To estimate the actual cost savings of labor to employers, the
Coast Guard determined the loaded wage rates of each type of occupation
(military, civilian in Government, and civilian out of Government)
affected by the final
[[Page 50082]]
rule.\13\ Commandant Instruction W presents loaded wage rates;
therefore, we did not apply a load factor adjustment for Coast Guard
military personnel. However, for Coast Guard civilian personnel and for
private sector workers outside of the Federal Government, we multiplied
the wage data obtained in the previous step by a load factor to
estimate the loaded wage rates for these employees. We calculated the
load factors to apply to Coast Guard civilian employees from total
compensation and wage data in the 2017 Congressional Budget Office
(CBO) report ``Comparing the Compensation of Federal and Private-Sector
Employees, 2011 to 2015.'' We calculated the load factor to apply to
private sector workers from BLS's ``Employer Cost for Employee
Compensation'' dataset for the fourth quarter of 2022.
---------------------------------------------------------------------------
\13\ A loaded hourly wage rate is what a company pays per hour
to employ a person, not the hourly wage an employee receives. The
loaded hourly wage rate includes the cost of non-wage benefits
(health insurance, vacation, etc.).
---------------------------------------------------------------------------
Costs
The Coast Guard finds no costs associated with this final rule. The
rule does not require actions of manufacturers nor vessel and facility
owners or operators. The rule is not retroactive, and existing vessels
are not required to be retrofitted.
This rule does not require owners or operators to acquire any
standards incorporated by reference; they will not need the standard in
hand to comply. Owners and operators need only look for evidence from
manufacturers that vessels or facilities meet or exceed the standard
before purchase; such evidence could be found in a contract for
purchase or repair of a vessel or facility or in product documentation
such as a user guide or warranty information. For these reasons, the
Coast Guard has not included a cost for the procurement of the newer
standards for vessel and facility owners or operators.
The Coast Guard estimates that the regulated public (manufacturers)
are currently in voluntary compliance with the requirements of the rule
based upon manufacturer participation in the development of industry
standards. When standards organizations formulate industry standards,
the standards undergo a process of review and comment by the industry.
Input from manufacturers is key to developing new standards that
consider the engineering capabilities of manufacturers. After the
review and comment process, the newer standard is voted upon at the
various governing bodies' committee meetings, and manufacturers are
among those voting. For this reason, the Coast Guard believes
manufacturers are aware and knowledgeable about the newer standards.
Given this, we further assume they already own copies of the standards
and, therefore, have not computed a cost for them to procure the
standards incorporated by reference.
Manufacturers have already been producing equipment to meet the
standard, and typically begin to make manufacturing modifications even
before such changes are adopted formally. Therefore, the Coast Guard
does not anticipate that there will be costs to retrofit manufacturing
equipment to comply with the final rule. For previous similar
rulemakings, no manufacturers commented that they would experience
incremental costs of production to comply with newer editions of
standards incorporated by reference.\14\ For these reasons, the Coast
Guard has not included a cost for these provisions. However, the Coast
Guard acknowledges that some manufacturers may need to purchase a newer
standard. The estimated incremental cost to do so varies according to
which standard is needed.\15\
---------------------------------------------------------------------------
\14\ A similar rulemaking is the Revision of Crane Regulation
Standards for Mobile Offshore Drilling Units, Offshore Supply
Vessels, and Floating Outer Continental Shelf Facilities proposed
rule, published May 13, 2013 (78 FR 27913) (Docket Number: USCG-
2011-0992).
\15\ We estimate the cost to acquire a standard by the equation
(0.25 hour x supervisory wage rate + 0.5 hour x admin assistant wage
rate + cost of purchasing a copy of the standard + shipping cost).
We base this equation on the publicly vetted cost estimation in the
regulatory analysis for the rule Revision of Crane Regulation
Standards for Mobile Offshore Drilling Units, Offshore Supply
Vessels, and Floating Outer Continental Shelf Facilities (Docket
Number: USCG-2011-0992).
---------------------------------------------------------------------------
Cost Savings
By amending 46 CFR subchapter F, this final rule eliminates
confusion from outdated and conflicting rules on marine engineering
safety for various vessel or facility components and systems and gives
the maritime industry clear instructions on how to comply with
regulations. Moreover, this final rule amends existing regulations to
reflect current national and international standards. The final rule
also generates cost savings to the regulated public and the Federal
Government.
Several of the rule's changes have no cost or cost savings impact.
These editorial changes, such as the removal of outdated terminology
and the consolidation of text, clarify regulations but do not result in
cost savings, as noted earlier. Also, by incorporating the newer
standards, the changes provide clarity and specificity. The Coast Guard
expects these changes to have no direct cost savings since they are
inseverable from the cost savings noted previously.
The compliance alternatives remove overly prescriptive
requirements, simplify regulatory compliance, and provide regulatory
flexibility for industry. In this rule, the Coast Guard includes the
compliance alternative to hydrostatic tests from the proposed rule,
thereby allowing the regulated public to perform an internal inspection
in lieu of the hydrostatic test. The inclusion of this compliance
alternative saves a given vessel owner labor and material to the extent
that it is used. To comply with the existing requirement for
hydrostatic tests, the vessel owner must remove existing lagging around
the unit, then replace it once the test is completed. The compliance
alternative involves less labor and does not necessitate the removal
and replacement of lagging as the existing requirements do. The Coast
Guard has not estimated a cost or cost savings for this alternative, as
it is unknown how many vessel owners or operators will choose to pursue
the alternative. Because equipment sizes vary, the amount of labor and
material needed to comply now and under the alternative is also
unknown.\16\
---------------------------------------------------------------------------
\16\ This information is needed to determine the existing cost
of compliance. Since it is unknown, the Coast Guard is unable to
estimate the cost savings of the new compliance alternative.
---------------------------------------------------------------------------
The quantifiable cost savings from the rule are due to a reduction
in the number of equivalency requests from the regulated public, as
well as time dedicated to continuing education on older standards.
There are also quantifiable cost savings for the Federal Government
because Coast Guard personnel will no longer have to review and approve
equivalency requests from the regulated public. Additionally, Coast
Guard employees will no longer need to continue with education on
older, outdated standards.
To estimate the cost savings of the final rule, the Coast Guard
first determined the wages of affected workers. For Coast Guard
military personnel, using Commandant Instruction W, we found the wage
rate for officers, who are engineers, at the O-3 and O-4 rank, to be
$89 and $105, respectively. We also found an hourly wage rate of $117
for a military supervisory engineer with a rank of O-5. The wage rates
in Commandant Instruction W are already loaded wage rates; therefore, a
load factor adjustment is not required. For Coast Guard civilian
personnel, we used hourly pay rates from OPM's pay table for Federal
[[Page 50083]]
Government workers in the Washington, DC, locality pay area for
calendar year 2022. The unloaded hourly wage rates for a GS-14 (step 5)
marine engineer and a GS-15 (step 5) marine engineering supervisor are
$68.55 and $80.63, respectively.
For private sector workers, we used the hourly wage rates reported
in the BLS ``Occupational Employment and Wage Statistics'' database for
May 2022. The unloaded mean hourly wage rate for ``Marine Engineers and
Naval Architects'' (occupational code 17-2121) is $50.75. The unloaded
mean hourly rate for an ``Architectural and Engineering Manager''
(occupational code 11-9041) is $78.52.\17\

rate: https://www.bls.gov/oes/2022/may/oes172121.htm for wage data

engineering managers. These pages were last visited on April 25,
2023.
---------------------------------------------------------------------------
Next, the Coast Guard determined the loaded mean hourly wage rates
to estimate the total cost savings of employees more accurately by
accounting for employees' non-wage benefits. For Coast Guard civilian
positions, we used a Congressional Budget Office (CBO) report
``Comparing the Compensation of Federal and Private-Sector Employees,
2011 to 2015,'' which includes information on Federal Government worker
average wages and average total compensation. We calculated a load
factor by dividing the average total compensation in Table 4 of the CBO
report by the average wages in Table 2 of the report for Federal
Government workers ``All Levels of Education.'' We obtained a load
factor of about 1.69 ($64.80 / $38.30).\18\
---------------------------------------------------------------------------

Compensation of Federal and Private-Sector Employees, 2011 to

---------------------------------------------------------------------------
We calculated the load factor (or benefits multipliers) for the
regulated public with fourth quarter 2022 data from the BLS's
``Employer Cost for Employee Compensation'' database were used for the
regulated public's wages.\19\ The Coast Guard determined the load
factor to be approximately 1.46, rounded, for private sector employees
by dividing total compensation for workers in ``Transportation and
Material Moving'' occupations by wages ($33.01 / $22.66 = 1.46). We
estimated the load factor for the applicable occupation category by
dividing the total compensation by the unloaded hourly wage rate. Table
5 displays the labor categories, the source of the wage rates, the
total compensation, the wage rates, and the calculated load factor.

----------------------------------------------------------------------------------------------------------------
After obtaining these load factors, the Coast Guard estimated the
cost savings to employers under the final rule. The Coast Guard assumed
a constant wage rate and a constant duration for tasks throughout the
period of analysis.\20\ We based these estimates using 2022 dollars.
---------------------------------------------------------------------------
\20\ Some tasks may take less time in the future due to
technological advances. However, the Coast Guard assumed no change
in the duration of tasks over the 10-year period of analysis.
---------------------------------------------------------------------------
The Coast Guard multiplied the unloaded wage rate for a ``Marine
Engineer and Naval Architect'' (occupational code 17-2121) of $50.75 by
the load factor of 1.46 to obtain a loaded mean hourly wage rate of
about $74.10 for this occupation. We also multiplied the unloaded
hourly rate for an ``Architectural and Engineering Manager''
(occupational code 11-9041) of $78.52, which we then multiplied by 1.46
to obtain a loaded mean hourly wage rate of about $114.64 for this
occupation.
For all provisions related to the Federal Government, the Coast
Guard used publicly available data as found in Commandant Instruction W
and in the OPM GS pay table to determine wage rates for Coast Guard
military and civilian personnel, respectively. The final rule has cost
savings for Coast Guard military and civilian engineers and their
supervisors at the MSC and in CG-ENG. We estimated the labor rate for a
civilian GS-14 engineer in the Coast Guard using a loaded mean hourly
wage rate of $115.85 (unloaded hourly wage rate of $68.55 x 1.69 load
factor). We also estimated a loaded mean hourly wage rate for a
civilian GS-15 engineering supervisor in the Coast Guard to be about
$136.26 (unloaded hourly wage rate of $80.63 x 1.69 load factor).
Military engineers at an O-3 or O-4 rank will be equally involved in
processing equivalency requests and staying educated on older
standards. Specifically, we expect that for each equivalency request,
either an O-3 or O-4 military engineer spends 1 hour reviewing and
verifying the accuracy of an equivalency request. We also expect that
six O-3 or O-4 military engineers each spend roughly 30 minutes each
year on maintaining awareness of older standards. Since engineers of
each rank are involved in these tasks, we used the average wage rate of
each one, which is $97 (($89 + $105) / 2).
According to Commandant Instruction W, the loaded wage rate for a
military supervisory engineer is $117 for an O-5. Table 6 presents a
summary of the hourly wage rates we used in this analysis.

Cost Savings to the Regulated Public
The final rule results in cost savings to the regulated public and
the Coast Guard from a reduction in the labor cost for processing
equivalency requests and the removal of the education labor cost for
the older standards that are incorporated by reference. An equivalency
is meant to provide an opportunity for a vessel or facility owner or
operator to still meet a regulatory requirement but allows them to do
so through a different arrangement or piece of equipment. The Coast
Guard expects this final rule to generate cost savings for owners or
operators of vessels or facilities who no longer need to request an
equivalency of subchapter F regulatory standards from the MSC.
Generally, the reason an owner or operator makes an equivalency request
is to seek a determination from the Coast Guard as to whether an
edition of an industry standard not codified in the CFR is sufficient
for use.
Based on MSC and CG-5PS data, the Coast Guard receives
approximately 200 equivalency requests annually. The Coast Guard
estimates it takes a civilian marine engineer or naval architect
employed by a vessel or facility owner approximately 40 hours of time
to develop an equivalency request and submit it to the Coast Guard for
review. An estimated 0.5 hours is needed for a supervisor engineer to
approve the work. The owner or operator of a vessel or facility asks
for an equivalency request from the Coast Guard by email. Because a
vessel or facility owner or operator makes an equivalency request by
email, we did not estimate a cost for this item.
In addition, the regulated public realizes cost savings from the
avoided cost of education for maintaining situational awareness on the
existing standards incorporated by reference, which the rule
eliminates. The Coast Guard estimates that 0.5 hours are spent annually
by engineers on education necessary to familiarize or re-familiarize
themselves with these standards. The Coast Guard believes that, as
industry standards evolve and advance, older editions may not be
readily accessible, even if they are incorporated by reference into the
CFR. As such, we expect that engineers find the older standards and
read them on occasion to maintain an awareness of how these standards
are different from current industry standards.
Cost Savings to the Coast Guard
The Coast Guard also experiences cost savings from the rule. When
the Coast Guard receives an equivalency request from a vessel or
facility owner or operator, a Coast Guard engineering staff member at
the MSC must review the request to provide a determination on whether
the standard(s) is equivalent to the existing standard(s) found in
subchapter F. The Coast Guard MSC engineer needs approximately 32 hours
to review an equivalency request, followed by 0.5 hours of supervisor
review. In a small percentage of more complex cases, the MSC works with
CG-5PS engineering staff to complete the equivalency review. Following
review, the MSC emails a decision back to the owner or operator. The
Coast Guard estimates it reviews 200 equivalency requests annually. To
calculate the costs avoided by Coast Guard no longer processing
equivalency requests, we multiplied the number of annual equivalency
requests by the sum of the duration of initial 1 hour of military
engineer review, 32 hours of civilian engineer review, and 30 minutes
of supervisory engineer review multiplied by the loaded wage rates of
the respective Coast Guard personnel performing the review (200
equivalency requests x (1 hour x average wage rate for military
engineer + 32 hours x wage rate for civilian engineer + 0.5 hours x
wage rate for civilian engineering supervisor)).
In addition, the Coast Guard will save labor costs annually,
because staff will no longer need to maintain an awareness of the older
versions of standards that are incorporated by reference. The rule
eliminates and replaces them with newer standards. The Coast Guard
estimates that a marine engineer with a vessel or facility owner or
manufacturer of vessels or vessel components who is tasked with working
on equivalency requests spend 0.5 hours annually on education on the
older standards. We similarly estimate that Coast Guard personnel also
spend 0.5 hours on education to maintain awareness and knowledge of
older standards. This applies to six civilian engineers and six
military engineers who work on equivalency requests. To calculate the
costs avoided by Coast Guard personnel no longer requiring education on
outdated standards, we multiplied 0.5 hours by the hourly wage rates of
the Coast Guard personnel (0.5 hours x (6 military engineers x average
wage rate for military engineer + 6 civilian engineers x wage rate for
civilian engineer)).
[[Page 50085]]
Cost Savings of the Rule
This rule will generate cost savings to two segments of the
regulated public: vessel or facility owners or operators and
manufacturers. For vessel or facility owners or operators, the Coast
Guard estimates that the annual undiscounted cost savings from a
reduced number of equivalency requests is about $604,264 (200
equivalency requests x (40 hours x $74.10 loaded wage of a marine
engineer + 0.5 hours x $114.64 loaded wage of an engineering manager)).
The annual undiscounted cost savings from avoided education on outdated
standards is about $7,410 (200 equivalency requests x (0.5 hours x
$74.10 loaded wage of a marine engineer)). For manufacturers, we
estimate that the annual undiscounted cost savings due to avoided
education on older standards is about $3,075 (83 manufacturers x (0.5
hours x $74.10 loaded wage of a marine engineer)). Therefore, the total
annual undiscounted cost savings to the regulated public is
approximately $614,749.
The Coast Guard estimates that the total annual undiscounted cost
savings to the Federal Government due to averted equivalency requests
is $774,466 (200 equivalency requests x ((32 hours x $115.85 loaded
wage of a civilian engineer) + (1 hour x $97 loaded wage of a uniformed
engineer) + (0.5 hours x $136.26 loaded wage of a civilian engineering
manager)). The estimated total annual undiscounted cost savings to the
Federal Government due to avoided education on outdated standards is
approximately $639 (0.5 hours x (6 civilian CG-5PS engineers x $115.85
loaded wage of a civilian engineer) + (6 uniformed engineers x $97
loaded wage of a uniformed engineer)). The total annual undiscounted
cost savings to the Federal Government is approximately $775,105.
The total undiscounted cost savings from the rule, therefore, is
approximately $1,389,854. Table 7 presents the estimated cost savings
of the rule to the regulated public and to the Coast Guard.
---------------------------------------------------------------------------
\21\ Existing regulations have been misunderstood as to whether
a pressure vessel (PV) requires or does not require plan review by
the Coast Guard. This change clarifies regulatory intent and will
preclude inquiries to the Coast Guard.
\22\ The requirement for Coast Guard numbering of PVs is often
misunderstood. The change clarifies that Coast Guard numbering is
required only when the Coast Guard has inspected the PV during
construction (shop inspection).
\23\ The requirement for use of the Coast Guard Symbol on PVs
(Sec. 54.10-3) often is misunderstood. This section has been edited
to assist readers in finding rules requiring stamping of the Coast
guard Symbol.
\24\ This section has been clarified by adding a section clearly
identifying which PVs do not require stamping.
\25\ The change gives operators the option of undergoing an
internal inspection every 10 years as opposed to requiring a
hydrostatic test every 10 years.

Unquantified Benefits
In this final rule, the Coast Guard is incorporating by reference
updated industry standards. These updated standards reflect the latest
available technologies, practices, and procedures that voluntary
consensus standards organizations, ship classification societies, or
maritime organizations recommend for use within the industry. The Coast
Guard is making these updates to harmonize the standards in the CFR
with the latest industry standards. As a result, these updates provide
the qualitative benefit of greater consistency between the CFR and
current industry practices. Updating to some newer editions of
standards also provides more flexibility for regulatory compliance. In
addition, the final rule provides qualitative benefits through certain
editorial changes that correct for inadvertent errors, remove obsolete
language, update Coast Guard contact information, standardize the use
of words and phrases in the CFR, account for relocation of certain
provisions, and standardize the designation of tables and figures.
These changes improve clarity of regulatory requirements and reduce
confusion, thereby improving service to the regulated public through
more accurate information.
Alternatives Considered
Within the Coast Guard's development of this rule, significant
alternatives to the regulatory component(s) were considered to
determine if any alternative could accomplish the stated objectives of
applicable statutes and could minimize any significant economic impact
of the rule on small entities beyond the rule. Among these alternatives
were the following:
[[Page 50087]]
Alternative 1: Take No Action
The Coast Guard could have chosen not to pursue the rulemaking.
Taking no action would cause no incremental costs to regulated entities
nor to the Coast Guard. However, in doing nothing, the Coast Guard
would have no mechanism to update regulations to reflect current
practices and improve their relevance to the public. There would be
neither an increase nor decrease in benefits to regulated entities due
to the alternative. The rule has been estimated to produce quantifiable
cost savings to the Coast Guard and the regulated public, which would
not be possible under the alternative of no action.
In addition, the standards currently incorporated by reference are
outdated. To keep them codified would, in theory, maintain existing
safety levels. However, because they are so outdated, they are sparsely
available. Compliance with them may become problematic in the future
due to lack of availability. The older editions of the standards do not
contain guidance for several current industry practices. Maintaining
the regulations with the existing standards incorporated by reference
does not allow for the cost savings the rule does.
We rejected this alternative because taking no action would not
provide additional benefits to the public. The public and the Coast
Guard, under this alternative, would not experience cost savings
through reduction in the number of submissions of equivalency requests
and ongoing education on outdated standards. Additionally, reliance on
older editions of standards in the CFR as industry practices continue
to evolve may cause confusion. By rejecting this alternative, the Coast
Guard will provide greater clarity of regulatory requirements and
better service to public with the final rule.
Alternative 2: Delay the Effective Date
The Coast Guard could have delayed the effective date beyond the 90
days after publication of the final rule currently provided. Delayed
effective dates are used to aid in compliance implementation,
particularly when the labor costs or capital costs are considerable.
The compliance costs for this rule are, as noted earlier, zero, and a
delayed effective date delays the cost savings opportunities to all
parties. For these reasons, the Coast Guard rejected this alternative.
Alternative 3: Exempt Small Entities
The Coast Guard could have exempted small entities from some or all
of the rule's provisions. In principle, an exemption could save small
entities time and money to comply with regulations. Exemptions for
small entities often are used when costs of compliance, such as capital
costs, are high. However, there are no costs of compliance for this
rule. For this alternative, an exemption may cause the cost savings
opportunities of the rulemaking to be precluded for small entities and,
thereby, the total value of the rule's cost savings declines
accordingly.
The rule implements requirements for business practices in which
the majority (if not all) of small businesses now engage. An exemption
for small business entities from the rulemaking would have little
effective and practical impact on small business entities. There is a
high level of voluntary compliance and limited applicability for the
affected population. The costs of compliance are zero and the rule is
applicable only if an actionable event occurs (for example, if a new
vessel is procured or an existing vessel undergoes a major conversion).
For these reasons, the Coast Guard did not pursue an exemption for
small entities.
B. Small Entities
Under the Regulatory Flexibility Act of 1980 (5 U.S.C. 601-612), we
have considered whether this final rule will have a significant
economic impact on a substantial number of small entities. The term
``small entities'' comprises small businesses, not-for-profit
organizations that are independently owned and operated and are not
dominant in their fields, and governmental jurisdictions with
populations of less than 50,000.
The rule creates cost savings for industry because we estimate
fewer equivalency requests will be submitted to the Coast Guard. We
expect equivalency requests to be submitted by owners or operators of
new U.S.-flagged vessels or facilities who may have questions about
standards that are not in 46 CFR subchapter F. Over a 6-year period,
from 2016-2021, we found 771 new U.S.-flagged vessels entered service,
or an average of about 129 annually during this period. We found that
156 companies owned the 771 vessels. The final rule also potentially
affects 22 nonprofits, under the conditions specified in the rule.
Using the publicly-available online database ``ReferenceUSAgov''
(in addition to individual online searches of companies) to search for
company-specific information, such as annual revenues and number of
employees, we found revenue and employee information on 139 of the 178
companies and nonprofits,\26\ or approximately 78 percent.\27\ Using
the Small Business Administration's (SBA) ``Table of Size Standards''
\28\ and the North American Industry Classification System (NAICS)
codes listed in the table, we found 49 of the 139 companies to be small
entities. We found the other 90 companies to be not small. We did not
find information on the remaining 38 companies and one nonprofit;
therefore, we assumed these companies to be small entities for a total
of 88 small entities out of 178, or approximately 49 percent.
---------------------------------------------------------------------------
\26\ Including colleges and universities, museums, and science
foundations.
\27\ Readers can access company-specific information at https://www.referenceusagov.com (last visited May 12, 2023).
\28\ The Coast Guard used the October 2022 version of the SBA's
table of size standards. Readers can access this version at the
following web page: https://www.sba.gov/sites/default/files/2022-09/Table%20of%20Size%20Standards_NAICS%202022%20Final%20Rule_Effective%20October%201%2C%202022.pdf (last visited May 12, 2023).
---------------------------------------------------------------------------
We analyzed the potential economic impacts of this final rule on
small entity companies and nonprofits and found that each entity that
no longer submits an equivalency request saves approximately $3,058
((40 hours x $74.10 loaded wage of a marine engineer or equivalent
employee) + (0.5 hours x $114.64 loaded wage rate of an engineering
manager or equivalent employee) + (0.5 hours x $74.10 loaded wage of a
marine engineer or equivalent employee)) annually. The cost savings of
$3,058 is less than 1 percent of annual revenue for 42 out of 47 small
entity companies and nonprofits for which we obtained revenue
information, or approximately 89 percent.\29\ We found cost savings to
revenue ratios of greater than 1 percent but less than 2 percent for
the five remaining small entity companies and non-profits.\30\
---------------------------------------------------------------------------
\29\ The Coast Guard found revenue data on a 48th small entity,
however, the reported revenue was $0, which we believe may have been
in error. Since we could not verify the accuracy of this reported
amount, we chose not to include this data point in our assessment of
the potential economic impacts of the rule on small entities.
\30\ For four small entity companies and one small entity
nonprofit, the impact from a reduced number of equivalency requests
would be greater than 1 percent and less than 2 percent of annual
revenues.
---------------------------------------------------------------------------
Additionally, the final rule potentially impacts manufacturers of
vessels or vessel or facility components. We estimate the average
potential cost savings to manufacturers for no longer needing education
older standards is about $57 ($114.64 loaded hourly wage of an
engineering manager x 0.5 hours).
Therefore, the Coast Guard certifies under 5 U.S.C. 605(b) that
this final rule
[[Page 50088]]
does not have a significant economic impact on a substantial number of
small entities because the cost savings of this final rule will have a
positive impact on revenues of less than 1 percent on nearly 90 percent
of the small entity owners that we researched. We also found that the
potential cost savings to manufacturers is less than 1 percent of
revenue among all manufacturers for which we could obtain revenue
information. Furthermore, no small entity that does not submit an
equivalency request will be impacted by any cost savings.
If you think that your business, organization, or governmental
jurisdiction qualifies as a small entity and that this rule will have a
significant economic impact on it, please submit a comment to docket at
the address in the ADDRESSES section. In your comment, explain why you
think it qualifies and how and to what degree this rule will affect it
economically.
C. Assistance for Small Entities
Under section 213(a) of the Small Business Regulatory Enforcement
Fairness Act of 1996, Public Law 104-121, we want to assist small
entities in understanding this rule so that they can better evaluate
its effects on them and participate in the rulemaking. If the rule
affects your small business, organization, or governmental jurisdiction
and you have questions concerning its provisions or options for
compliance, please call or email the person in the FOR FURTHER
INFORMATION CONTACT section of this rule. The Coast Guard will not
retaliate against small entities that question or complain about this
rule or any policy or action of the Coast Guard.
Small businesses may send comments on the actions of Federal
employees who enforce, or otherwise determine compliance with, Federal
regulations to the Small Business and Agriculture Regulatory
Enforcement Ombudsman and the Regional Small Business Regulatory
Fairness Boards. The Ombudsman evaluates these actions annually and
rates each agency's responsiveness to small business. If you wish to
comment on actions by employees of the Coast Guard, call 1-888-REG-FAIR
(1-888-734-3247).
D. Collection of Information
The Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520) requires
the U.S. Coast Guard to consider the impact of paperwork and other
information collection burdens imposed on the public. As defined in 5
CFR 1320.3(c), ``collection of information'' comprises reporting,
recordkeeping, monitoring, posting, labeling, and other similar
actions.
This rule does not require a modification of an existing collection
of information and does not call for new collection of information
under the Paperwork Reduction Act.
E. Federalism
A rule has implications for federalism under Executive Order 13132
(Federalism) if it has a substantial direct effect on the States, on
the relationship between the national Government and the States, or on
the distribution of power and responsibilities among the various levels
of Government. We have analyzed this rule under Executive Order 13132
and determined that it is consistent with the fundamental federalism
principles and preemption requirements described in Executive Order
13132. Our analysis follows.
It is well settled that States may not regulate in categories
reserved by Congress for regulation by the Coast Guard. It is also well
settled that all of the categories regulated under 43 U.S.C. 1333 and
46 U.S.C. 3306 and 3703, as well as any other category in which
Congress intended the Coast Guard to be the sole source of a vessel's
obligations, are within the field foreclosed from regulation by the
States. See United States v. Locke and Intertanko v. Locke, 529 U.S. 89
(2000). This rulemaking updates the references to incorporated
standards in 46 CFR subchapter F, which is authorized under 43 U.S.C.
1333, 46 U.S.C. 3306, and 46 U.S.C. 3703. Therefore, because the States
may not regulate within these categories, this rule is consistent with
the fundamental federalism principles and preemption requirements
described in Executive Order 13132.
While it is well settled that States may not regulate in categories
in which Congress intended the Coast Guard to be the sole source of a
vessel's obligations, the Coast Guard recognizes the key role that
State and local governments may have in making regulatory
determinations. Additionally, for rules with federalism implications
and preemptive effect, Executive Order 13132 specifically directs
agencies to consult with State and local Governments during the
rulemaking process. If you believe this rule has implications for
federalism under Executive Order 13132, please contact the person
listed in the FOR FURTHER INFORMATION section of this preamble.
F. Unfunded Mandates Reform Act
The Unfunded Mandates Reform Act of 1995, 2 U.S.C. 1531-1538,
requires Federal agencies to assess the effects of their discretionary
regulatory actions. In particular, the Act addresses actions that may
result in the expenditure by a State, local, or tribal government, in
the aggregate, or by the private sector of $100,000,000 (adjusted for
inflation) or more in any one year. Although this rule does not result
in such an expenditure, we do discuss the effects of this rule
elsewhere in this preamble.
G. Taking of Private Property
This rule does not cause a taking of private property or otherwise
have taking implications under Executive Order 12630 (Governmental
Actions and Interference with Constitutionally Protected Property
Rights).
H. Civil Justice Reform
This rule meets applicable standards in sections 3(a) and 3(b)(2)
of Executive Order 12988, (Civil Justice Reform), to minimize
litigation, eliminate ambiguity, and reduce burden.
I. Protection of Children
We have analyzed this rule under Executive Order 13045 (Protection
of Children from Environmental Health Risks and Safety Risks). This
rule is not an economically significant rule and does not create an
environmental risk to health or risk to safety that might
disproportionately affect children.
J. Indian Tribal Governments
This rule does not have Tribal implications under Executive Order
13175 (Consultation and Coordination with Indian Tribal Governments),
because it does not have a substantial direct effect on one or more
Tribal governments, on the relationship between the Federal Government
and Tribal governments, or on the distribution of power and
responsibilities between the Federal Government and Tribal governments.
K. Energy Effects
We have analyzed this rule under Executive Order 13211 (Actions
Concerning Regulations That Significantly Affect Energy Supply,
Distribution, or Use). We have determined that it is not a
``significant energy action'' under that order because it is not a
``significant regulatory action'' under Executive Order 12866 and is
not likely to have a significant adverse effect on the supply,
distribution, or use of energy.
L. Technical Standards
The National Technology Transfer and Advancement Act, codified as a
note to 15 U.S.C. 272, directs agencies to use voluntary consensus
standards in
[[Page 50089]]
their regulatory activities unless the agency provides Congress,
through OMB, with an explanation of why using these standards would be
inconsistent with applicable law or otherwise impractical. Voluntary
consensus standards are technical standards (such as specifications for
materials, performance, design, or operation; test methods; sampling
procedures; and related management systems practices) that are
developed or adopted by voluntary consensus standards bodies.
This rule uses the following voluntary standards:
