International Guidelines for the Safe Operation of Dynamically Positioned Offshore Supply Vessels
Year: 2022 Language: English Author: IMCA, Marine Safety Forum Genre: Rules/Guide Publisher: IMCA Edition: 182 MSF Rev.4 Format: PDF Quality: eBook Pages count: 67 Description: These guidelines were originally developed by an international cross-industry workgroup and have more recently been updated by the Marine Safety Forum in conjunction with IMCA and the Guidelines for Offshore Marine Operations (GOMO) Group. The intention is that this document will provide guidance, when DP is to be used on an offshore supply vessel, which is suitable for international application. These guidelines primarily apply to DP equipped offshore supply vessels but may also include all other types of vessels carrying out supply and other ancillary operations (usually accepted as cargo, anchor-handling and towing operations), when in DP mode either inside, or outside of, the 500 metres safety zone of an offshore installation. These guidelines do not preclude non-DP-equipped vessels from carrying out supply operations but merely offer guidance to those using DP. Acceptance of the limitations of vessels, and decisions on suitability of DP use inside installation safety zones, shall always lie with the charterer. The purpose of these guidelines is to make risk management tools available, to vessel operators, charterers, Masters and Officers that will help ensure safe operation of DP offshore supply vessels in automatic DP mode.
