API RP 2D

Description

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 document also provides requirements and recommendations for lift planning, pre-use inspection, and testing of temporary cranes that are erected offshore. 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 document.
