API RP 2D
Operation and Maintenance of Offshore Cranes
|Publication Date:||1 December 2014|
This standard establishes general principles for the safe operation and maintenance of offshore pedestal-mounted revolving cranes on fixed or floating offshore platforms, offshore support vessels, jackup drilling rigs, semi-submersible drilling rigs and other types of mobile offshore drilling units (MODUs), as a companion to API 2C and API 2D-2. This standard also provides requirements and recommendations for lift planning, pre-use inspection, and testing of temporary cranes that are erected offshore.
Typical applications can include:
a) Offshore oil exploration and production applications: These cranes are typically mounted on a fixed (bottom-supported) structure, floating platform structure, or vessel used in drilling and production operations.
b) Shipboard applications: These lifting devices 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.
c) Crane vessel applications: These cranes are typically mounted on ship-shaped vessels, semisubmersibles, 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.
Equipment (e.g. davits, launch frames) used only for launching life-saving appliances (life boats or life rafts) are not included in the scope of this standard.
Lifting devices not covered by this standard would be operated, inspected, and maintained in accordance with the manufacturer's recommendations.
