Harvey Gulf Completes First LNG Bunkering

| USA, New Orleans LA

Harvey Energy OSV - LNG tank positionHarvey Gulf International Marine LLC made maritime history in North America last Friday by being not only the first owner/operator of a dual-fuel offshore support vessel to bunker LNG as a marine fuel, but to also successfully complete the first truck-to-vessel transfer of LNG and to power M/V Harvey Energy on LNG.

Harvey Energy, built at Gulf Coast Shipyard Group in Gulfport, Miss., is based on the Vard Marine 1 311 design and is 310 x 64 x 24.5 feet, powered by three Wartsila 6L34DF dual-fuel gensets providing 7.5 MW of power fueled by Wartsila’s LNGPac system. Harvey Energy is U.S.-flagged Subchapter I and L, SOLAS compliant and is classed by the ABS as +A1, OSV, +AMS, +DPS-2, +ACCU, UWILD, FFV-1, ENVIRO+, GP, GFS (dual fuel diesel) E. With 5,150 tons of deadweight, the vessel is capable of carrying 253,000 gallons of fuel oil, 18, 000 barrels of liquid mud, 1,600 barrels of methanol, 10,250 cubic feet of dry cement and 78,000 gallons of LNG fuel.

This historic bunkering took place at a shore-based terminal owned by a subsidiary of Martin Midstream Partners LP in Pascagoula, Miss. The cool-down process took approximately 12 hours to achieve the desired tank temperature and pressure utilizing 3,800 gallons of nitrogen. The LNG bunkering was successfully completed within a few hours of cool-down. Harvey Energy will next proceed to LNG trials before delivery.

Harvey Gulf's LNG facility layoutIn concert with Harvey Energy, Harvey Gulf is preparing to operate the first LNG marine fueling facility in the United States, located at its vessel facility in Port Fourchon, La. The fueling facility will be a vital addition to the growing national LNG supply infrastructure, supporting critical operations of the oil and gas industry’s offshore support vessel fleet operating on clean-burning LNG.

Harvey Gulf International Marine, founded in 1955, is a privately owned and operated marine transportation company that specializes in providing, fast supply vessels, offshore supply and multi-purpose support vessels for deepwater operations.
