Offshore cranes are defined as pedestal mounted elevating
and rotating lift devices for transfer of materials or personnel to or from marine
vessels and structures. Offshore cranes are typically mounted
on a fixed (bottom supported) or floating platform structure
used in drilling and production operations. API Spec 2C is not
intended to be used for the design, fabrication, and testing of
davits and/or emergency escape devices. API Spec 2C is also
not intended to be used for shipboard cranes or heavy lift
cranes. Shipboard cranes are mounted on surface type vessels
and are used to move cargo, containers, and other materials
while the crane is within a harbor or sheltered area. Heavy lift
cranes are mounted on barges or other vessels and are used in
construction and salvage operations within a harbor or sheltered
area or in very mild offshore environmental conditions. |
