RINA approves new OSV rules and Environment notations

RINA approves new OSV rules and Environment notations

International classification society RINA has launched new rules for Offshore Support Vessels, new environmental notations covering cargo handling and transhipment operations and a new guide on complete ship model calculation of passenger ships.

All these initiatives were approved at a meeting of RINA’s technical committee held in Genoa this week.

OSV Rules

The free-standing and user-friendly Offshore Support Vessels (OSV) Rules have been developed in response to requests from shipyards and operators.

Ships complying with the new rules are assigned the Service Notation Offshore Support Vessel followed by at least one of the following service features defining the specialised service:  

supply - for OSVs specially intended to provide facilities and assistance for the performance of offshore activities.

tug - for OSVs specially equipped for towing.

salvage tug - for OSVs specially equipped for towing having specific equipment for salvage.

escort tug - for OSVs specially equipped for towing and having specific equipment for escorting ships or other units during navigation.

fire-fighting - for OSVs specially intended and equipped for fighting fire.

oil recovery - for OSVs specially equipped with fixed installations and/or mobile equipment for the removal of oil from the sea surface and its retention on board, carriage and subsequent unloading.

diving support - for OSVs equipped to support diving operations, which are provided with a diving system.

cable laying - for OSVs specially equipped for the carriage and/or laying, hauling and repair of submarine cables.

pipe laying - for OSVs specially equipped for the carriage and/or laying, hauling and repair of submarine pipes. 

In addition, in order to better describe the specific technical capabilities, equipment and arrangements, RINA has established a number of additional service features and additional class notations that may be assigned to an OSV, such as anchor handling and dynamic positioning.
