The company announced on Friday its dual fuel offshore support vessel (OSV) M/V Harvey Energy has bunkered LNG as a marine fuel, becoming the first North American owner/operator of a dual fuel OSV to bunker LNG and the first to also successfully complete the first truck-to-vessel transfer of LNG. The bunkering took place at a shore-based terminal owned by a subsidiary of Martin Midstream Partners L.P. 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. The Harvey Energy will next proceed to LNG trials before delivery.
“Today’s historic event is an example of Harvey Gulf’s commitment to their customers and the environment to provide the most affordable, innovative, environmentally friendly technology solutions to meet their business demands,” said Shane Guidry, Chairman and CEO of Harvey Gulf International Marine.
The Harvey Energy, built at Gulf Coast Shipbuilding Group’s Gulfport, MS, shipyard is based on the Vard Marine 1 311 design and is a 310 ft x64 ft x 24.5ft PSV powered by three Wärtsilä 6L34DF dual fuel gensets providing 7.5 MW of power and fueled by Wärtsilä’s LNGPac system. The 5,150 dot vessel is capable of carrying 253,000 USG of fuel oil, 18,000 bbls of liquid mud, 1,600 bbls of methanol, 10,250 cu. ft of dry cement and 78,000 USG of LNG fuel.
Harvey Gulf is also preparing to operate the first LNG marine fueling facility in the United States, located at its vessel facility in Port Fourchon, LA. It will be a significant 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.
