Current through Register 2024 Notice Reg. No. 38, September 20, 2024
For land cranes/derricks used on barges, pontoons,
vessels or other means of flotation, the employer shall ensure that:
(a) The rated capacity of the equipment
(including but not limited to modification of load charts) applicable for use
on land is reduced to:
(1) Account for
increased loading from list, trim, wave action, and wind.
(2) Be applicable to a specified location(s)
on the specific barge, pontoons, vessel or other means of flotation that will
be used, under the environmental conditions expected and encountered.
(3) The conditions required in subsections
(c) and (d) are met.
(b)
The rated capacity modification required in subsection (a) is performed by the
equipment manufacturer, or a certified agent who has expertise with respect to
both land crane/derrick capacity and the stability of vessels/flotation
devices.
(c) For list and trim.
(1) The maximum allowable list and the
maximum allowable trim for the barge, pontoon, vessel or other means of
flotation shall not exceed the amount necessary to ensure that the conditions
in subsection (d) are met. In addition, the maximum allowable list and the
maximum allowable trim shall not exceed the least of the following: 5 degrees,
the amount specified by the crane/derrick manufacturer, or, when, an amount is
not so specified, the amount specified by the certified agent.
(2) The maximum allowable list and the
maximum allowable trim for the land crane/derrick shall not exceed the amount
specified by the crane/derrick manufacturer, or, when, an amount is not so
specified, the amount specified by the certified agent.
(d) For the following conditions:
(1) All deck surfaces of the barge, pontoons,
vessel or other means of flotation used are above water.
(2) The entire bottom area of the barge,
pontoons, vessel or other means of flotation used is
submerged.
(e) Physical
attachment, corralling, rails system and centerline cable system shall meet the
requirements in Option (1), Option (2), Option (3), or Option (4) of this
section, and that whichever option is used shall also meet the requirements of
subsection (e)(5).
(1) Option (1) - Physical
attachment. The crane/derrick is physically attached to the barge, pontoons,
vessel or other means of flotation. Methods of physical attachment include
crossed-cable systems attached to the crane/derrick and vessel/flotation
device, bolting or welding the crane/derrick to the vessel/flotation device,
strapping the crane/derrick to the vessel/flotation device with chains, or
other methods of physical attachment.
(2) Option (2) - Corralling. The
crane/derrick is prevented from shifting by installing barricade restraints
(i.e., a corralling system). Employers shall ensure that corralling systems do
not allow the equipment to shift by any amount of shifting in any
direction.
(3) Option (3) - Rails.
The crane/derrick shall be prevented from shifting by being mounted on a rail
system. Employers shall ensure that rail clamps and rail stops are used unless
the system is designed to prevent movement during operation by other
means.
(4) Option (4) - Centerline
cable system. The crane/derrick is prevented from shifting by being mounted to
a wire rope system. The employer shall ensure that the wire rope system meets
the following requirements:
(A) The wire rope
and attachments are of sufficient size and strength to support the side load of
the crane/derrick.
(B) The wire
rope is attached physically to the vessel/flotation device.
(C) The wire rope is attached to the
crane/derrick by appropriate attachment methods (such as shackles or sheaves)
on the undercarriage, and that the method used will allow the crew to secure
the crane/derrick from movement during operation and to move the crane/derrick
longitudinally along the vessel/flotation device for repositioning.
(D) Means are installed to prevent the
crane/derrick from passing the forward or aft end of the wire rope
attachments.
(E) The crane/derrick
is secured from movement during operation.
(5) The systems/means used to comply with
Option (1), Option (2), Option (3), or Option (4) of this section are designed
by a licensed marine engineer, or registered professional engineer familiar
with floating crane/derrick design.
EXCEPTION TO SUBSECTION (e):
For mobile auxiliary cranes used on the deck of a
floating crane/derrick, the requirement specified by subsection (e) to use
Option (1), Option (2), Option (3), or Option (4) does not apply when the
employer demonstrates implementation of a plan and procedures that meet the
following requirements:
(1) A marine
engineer or registered professional engineer familiar with floating
crane/derrick design develops and signs a written plan for the use of the
mobile auxiliary crane.
(2) The
plan is designed so that the applicable requirements of this section are met
despite the position, travel, operation, and lack of physical attachment (or
corralling, use of rails or cable system) of the mobile auxiliary
crane.
(3) The plan specifies the
areas of the deck where the mobile auxiliary crane is permitted to be
positioned, travel, and operate, and the parameters and limitations of such
movements and operation.
(4) The
deck is marked to identify the permitted areas for positioning, travel, and
operation.
(5) The plan specifies
the dynamic and environmental conditions that shall be present for use of the
plan.
(6) If the dynamic and
environmental conditions in exception (5) are exceeded, the mobile auxiliary
crane shall be attached physically or corralled in accordance with Option (1),
Option (2) or Option (4) of subsection (e).
(f) The barge, pontoons, vessel or other
means of flotation used:
(1) Are structurally
sufficient to withstand the static and dynamic loads of the crane/derrick when
operating at the crane/derrick's maximum rated capacity with all anticipated
deck loads and ballasted compartments.
(2) Have a subdivided hull with one or more
longitudinal watertight bulkheads for reducing the free surface
effect.
(3) Have access to void
compartments to allow for inspection and pumping.
