Harvey Gulf International Marine on Friday made LNG bunkering history when the lead vessel in its new line of dual fuel offshore supply vessels became the first such vessel in North America to bunker LNG as a marine fuel.

The historic truck-to-vessel bunkering of the MV Harvey Energy took place on Friday at a shore-based terminal owned by a subsidiary of Martin Midstream Partners L.P. in Pascagoula, Mississippi. According to Harvey Gulf, the cool-down process utilized 3,800 gallons of nitrogen and took approximately 12 hours to reach the desired tank temperature and pressure. The LNG bunkering was then successfully completed within a few hours of cool-down.

The MV Harvey Energy was built at Gulf Coast Shipyard Group’s shipyard in Gulfport, MS and is based on the Vard Marine 1 311 design. The ship features three Wartsila 6L34DF dual fuel gensets providing 7.5MW of power fueled by Wartsila’s LNGPac system.

Shane Guidry, Chairman and CEO of Harvey Gulf, commented. “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.”

Along with the crew of the Harvey Engery, also on-hand participate in the bunkering was the U.S. Coast Guard, ABS, Wartsila, Martin Energy Services LLC, State and Local Agencies and GCSG.

The MV Harvey Energy, the first of six similar dual fuel PSVs being built at GCSG, will next proceed to LNG trials prior to delivery.

In concert with the Harvey Energy class, Harvey Gulf is preparing to operate the first LNG marine fueling facility in the United States at its vessel facility in Port Fourchon, Louisiana.
