API Spec 2C-2012
Offshore Pedestal-mounted Cranes
Edition: 7th
American Petroleum Institute / 01-Mar-2012 / 136 pages
Previous Versions: API Spec 2C-2004
Scope
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 or personnel to or from marine vessels, barges and structures.
Typical applications can include:
a) offshore oil exploration and production applications; these cranes are typically mounted on a fixed (bottomsupported) structure, floating platform structure, or ship-hulled 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) heavy-lift applications; cranes for heavy-lift applications are mounted on barges, self-elevating vessels or other vessels, and are used in construction and salvage operations within a harbor or sheltered area or in limited (mild) environmental conditions.
Figure 1 illustrates some (but not all) of the types of cranes covered under this specification. 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. Additionally, this specification does not cover the use of cranes for subsea lifting and lowering operations or constant-tension systems.
