TY Offshore announced that Harvey Gulf International Marine has ordered the construction of an additional TY Offshore built 302’ x 64’ Dual Fuel Offshore Supply Vessel, bringing its total order to six. The order, and subsequent delivery, positions Harvey Gulf as the largest owner/operator of clean burning LNG Offshore Support Vessels in the world. TY Offshore is building all six vessels at their Gulfport, Mississippi shipyard.

The vessels are powered by cleaner-burning natural gas and will achieve “ENVIRO+, Green Passport” Certification by the American Bureau of Shipping. The requirements for this certification include, among others, that the vessels be continuously manned with a certified Environmental Officer, be completely constructed with certified environmentally-friendly materials, and have advanced alarms for fuel tanks and containment systems. These are the first OSV’s to achieve this certification, making them the most environmental friendly OSV’s in Gulf of Mexico.

To achieve environmentally friendly status, the vessels will be outfitted with Wartsila's 6L34DF (DF=Duel Fuel LNG/Diesel) Gensets, Wartsila Transverse and Steerable Thrusters, Wartsila Switchgear and Wartsila I.A.S. Machinery Control, Alarm and Monitoring System. Operating in LNG mode provides less noxious emissions than with diesel fuel. The system is designed to maximize fuel efficiency and economical power generation for all operating conditions and is ABS certified. The two AC propulsion drive motors each have a maximum continuous rating of 3620 HP (2700 kW), variable input speed up to a maximum RPM continuous rating.
