Section 1437 – Floating Cranes/Derricks and Land Cranes/Derricks on Barges
This section contains requirements for floating cranes and derricks that supplement the other requirements of the standard. Because this equipment is highly specialized and is not used by most construction employers, this information will only address a few of the areas where additional or different requirements are specified for this type of equipment.
Inspections
Additional items must be inspected during the shift, monthly, and annual inspections. In addition, every four years, a marine engineer, marine architect, licensed surveyor, or other qualified person who has expertise with respect to vessels/flotation devices must survey the internal portion of the barge, pontoons, vessel, or other means of flotation.
Safety Devices
The following additional safety devices are required: barge, pontoon, vessel, or other means of flotation list and trim device; positive equipment house lock; wind speed and direction indicator (if a competent person determines that wind is a factor that needs to be considered).
Working with a Diver
When a crane/derrick is used to lift a diver or divers into and out of the water, it must not be used for any other purpose until all the divers are back on board.
Land Cranes/Derricks on Flotation Devices
The rated capacity must be reduced to take into account the additional sources of instability (list, trim, wave action, and wind) resulting from operating on water. Alternative means of physical attachment and an exception to the requirement for physical attachment are specified.
Equipment Designed for Use on Flotation Devices
Requirements for maximum list, trim, and wind speed are specified. Additional rules to ensure the structural integrity and stability of the equipment apply to employer-made (as opposed to manufacturer- made) equipment.
