海上基座式起重机规范（第六版

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 ship-shaped vessels, semi-submersibles, barge, or self-elevating type marine vessels special
