Harvey Gulf International Marine said it has completed the first truck to vessel transfer of liquefied natural gas to power the M/V Harvey Energy on LNG.
The Harvey Energy built at GCSG in Gulfport, is based on the Vard Marine 1 311 design and is powered by 3 Wartsila 6L34DF dual fuel gensets providing 7.5MW of power fueled by Wartsila’s LNGPac system. With 5,150 tons of deadweight, the vessel is capable of carrying 253,000 USG of Fuel Oil, 18, 000 Bbls of Liquid Mud, 1,600 Bbls of Methanol, 10, 250ft3 of Dry Cement and 78,000 USG of LNG fuel.
This bunkering took place at a shore-based terminal owned by a subsidiary of Martin Midstream Partners in Pascagoula, the company informed in a statement.
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 completed within a few hours of cool-down. The Harvey Energy will next proceed to LNG trials before delivery.
In concert with the 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, Louisiana.
