This standard covers the design, materials, fabrication, installation, testing and commissioning of offshore cranes and platform cranes.

The categorization of lifting appliances is based on installation and intended function for the lifting appliance:

Offshore cranes:

lifting appliances on board vessels intended for load handling outside vessels while at open sea

Platform cranes:

lifting appliances onboard offshore units/installations intended for load handling within and outside the unit/installation while in harbour and within the unit/installation while at sea.

Each lifting appliance has its separate intended functions. Examples of intended functions are, but not limited to:

cargo handling within deck area on board offshore units/installations

loading and discharging of offshore supply vessels

launch and recovery of diving systems

launch and recovery of ROV

loading and discharging from sea or sea bed

pipe/cable laying

personnel handling

Requirements presented herein are minimum requirements to be satisfied, although subject to acceptance by the Society, other minimum requirements may be agreed e.g. based on new technology available at the time of application for certification.

The requirements of this standard may be supplemented with additional requirements where installation of specific design or assessment shows that standards that provides equivalent or higher level of integrity and safety are more appropriate.

The standard consists of a three level hierarchy of documents.

Sec.1 and Sec.2 provides principles and procedures of the Society's classification, certification, verification and consultancy services.

Sec.3 through Sec.14 provides technical provisions and acceptance criteria as well as the technical basis for the services stated in the first two sections.

Appendices, provides proven technology and sound engineering practice as well as guidance for the higher level documents mentioned in this document.

This standard distinguishes between:

information and description of services

requirements.

Consequently, these two subjects are separated, and the standard is divided into three parts:

Sec.1 - Sec.2: General information, application, definitions and references. Description of applicable services and relations to rules and regulation from institutions other than the Society

Sec.3 - Sec.14: Requirements and technical provisions

Appendices.
