API Spec 2C

This specification provides requirements for design, construction, and testing of new offshore pedestal-mounted cranes. For the purposes of this specification, offshore cranes are defined as pedestal-mounted elevating and rotating lift devices for transfer of materials and personnel to or from marine vessels, barges and structures; or for transfer of materials to or from the sea or the seabed.

Typical applications can include:

a) offshore oil exploration and production applications—these cranes are typically mounted on a fixed (bottom-supported) structure, floating structure, or vessel used in drilling and production operations;

b) shipboard applications—these 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; and

c) crane vessel applications—these cranes are typically mounted on shipshaped vessels, semi-submersibles, barges, or self-elevating type marine vessels specialized in lifting heavy and/or unique loads for construction, pipe lay, renewable energy, salvage, and subsea applications in both harbor and offshore waters.

While there are many configurations of pedestal-mounted cranes covered in the scope of this specification, it is not intended to be used for the design, fabrication, and testing of davits or emergency escape devices. This specification does not cover the use of cranes for life-saving applications, or for the launch and recovery of manned underwater units, such as diving bells or submersibles.
