Harvey Gulf International Marine, LLC celebrated a historic milestone by conducting the first gas fuel bunkering procedure of their newest offshore support vessel (OSV), Harvey Energy. Under ABS class, the Harvey Energy is the first gas-fueled vessel to be flagged with the US and the first LNG-powered vessel in service in North America.
The dual-fuel diesel OSV was constructed by Gulf Coast Shipyard Group (GCSG) and is powered by three Wärtsilä 6L34DF dual-fuel gensets providing 7.5 MW of power that are supplied fuel via Wärtsilä’s LNGPac system.
Harvey Gulf’s historic bunker event occurred in early February at the Martin Energy Services facility in Pascagoula, Mississippi, and was supported by Harvey Energy’s crew, Wärtsilä, Martin Energy, Gulf Coast Shipyard Group, Shell, ABS and the US Coast Guard (USCG). The bunker transfer included a truck to vessel transfer of liquefied nitrogen and LNG.
As LNG becomes a more sustainable and economical fuel source for the marine and offshore industries to comply with North American ECA standards, ABS is working closely with industry and regulatory bodies including the USCG to verify the LNG ship designs’ compliance with the applicable standards, class Rules and regulations to promote safety and consistency to the application of the new requirements for gas-fueled vessels.
According to Harvey Gulf, the vessel will be based out of Port Fourchon, Louisiana, and will immediately begin its long-term charter role.
