OSVs that lower emissions and require less fuel. The Lockport, La. company is building a series of diesel-electric, offshore supply vessels now. Managing Director Walter Thomassie explains, ?They?ll allow for reduced emissions based on an optimized hull design, and the ef ciency of the power plant system allows the vessels to reduce fuel burn signi cantly over conventional designs.? The vessels have also earned the following class string-- ABS, AMS, A1, Circle E, Enviro, DP-2, FiFi-1, USCG Sub I & L.? The  rst OSV in the series will be delivered at the end of the year, followed by one in July 2013, another in September 2013 and a fourth in January 2014. ?When we began this program in late 2010, our decision to build was market driven,? Thomassie said. ?Thoma-Sea and our customer at the time of design, Gulf Offshore Logistics, felt that we needed to offer a highly ef cient, environmentally friendly option for servicing the offshore sector. The concept was developed in conjunction with Technology Associates, Inc. or TAI, the naval architects that did the engineering on the design.? TAI is headquartered in New Orleans. In 2010, Thoma-Sea merged its Lockport and Houma, La. facilities under one entity, Thoma-Sea Marine Constructors. The company also recently sold two, diesel-electric- powered platform supply vessels to GulfMark Americas. BORDELON USES ENGINES THAT REDUCE EMISSIONSBordelon Marine Inc. is building three 252-foot PSVs in Houma, La., with engines that will reduce emissions, Wes Bordelon, President and CEO said. ?We began the design process in 2010,? he said. ?And even though it wasn?t a requirement at that time, we decided to make our new vessels Tier 3 compliant.? EPA Tier 3 emission standards reduce NOx and other emissions. The Stringrays? propulsion will be supplied by two Cummins QSK 60-M, Tier 3-compliant diesel engines that each drive a Schottel 1215, 220 hp Z-Drive. Each vessel will have two Schottel STT2, 1020 hp bow thrusters. ?The Stingray design ?
