Harvey Gulf Exercises Option for Sixth TY Offshore Dual Fuel Offshore Vessel

June 3, 2013, Gulfport, Mississippi: TY Offshore is pleased to announce 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.

Harvey Gulf CEO, Shane J. Guidry, announced the signing, saying, “My commitment to our clients, the environment and our industry is clear. We are the only company in America building Offshore Supply Vessels utilizing liquefied natural gas (LNG) as its fuel source regardless of the fact that these vessels have a construction cost of twenty (20%) percent higher than a conventional Offshore Supply Vessel.”

 John Dane III, TY Offshore’s President and CEO, stated, “We appreciate Harvey Gulf’s confidence in our shipyard. To have several follow on orders—and to be building the largest LNG fleet in the world—is significant for us. We are delighted to show our commitment to evolving LNG technology through our engineering and build skills. Of course, the confidence Harvey Gulf puts in us also ensures steady employment over the next 36 months.”

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.

Founded in 1955, Harvey Gulf International Marine is a marine transportation company that specializes in towing drilling rigs and providing offshore supply and multi-purpose support vessels for deepwater operations in the U.S. Gulf of Mexico.
