The present standard was released by DNV GL to provide requirements for certification/verification of the lifting appliances that are intended for handling loads outside ships at sea and on board ships and offshore installations. The document is covering the design and materials, fabrication and installation, testing and commissioning of the offshore and platform lifting gear.

The book starts with the general information on the lifting appliances and their categorization, followed by the section addressing documentation and certification of cranes. The structural design and strength issues have been dealt with in a separate section.

The main part of the document covers safety matters and equipment, offshore and platform cranes, subsea operations, lifting of personnel, LARS, i.e. launch and recovery systems for ROV and diving, testing requirements and other information.

There are several appendices providing additional information, such as marking of the single sheave crane blocks, instruction on the examination of the skids and pad eyes, wind loads to be considered, verification guidelines for safety functions, lifting gear register form, certificate forms etc.
