Offshore Platform Supply Vessel Opportunities Seized By Wärtsilä
News in the past week boosted diesel engine manufacturer Wärtsilä's business in the offshore platform supply vessel sector: First a major contract to design and power a series of four multi-purpose platform support vessels (MPSVs) for Malaysian-based international offshore oilfield services provider Bumi Armada Berhad. Then, from the other side of the world, came word that the United States Environmental Protection Agency (EPA) had certified the company’s 34DF engine (soon to be installed in a new series of Gulf of Mexico US-flag platform support vessels) as emission standard compliant.

Wärtsilä will supply a comprehensive design and propulsion package for each of the four vessels to be built by a subsidiary of Nam Cheong Limited, in one of its subcontracted yards, Fujian Mawei Shipbuilding Ltd, in China.

The contract comprises the basic customised design, the main diesel-electric propulsion power generation system, the Wärtsilä Low Loss Concept (LLC)electrical system (an energy efficient and highly redundant power distribution system for electric propulsion applications) and the automation system.
The WSD 1000 design for the LOA 88.8m (291ft) MPSV’s includes four gensets whose power (in excess of 6MW) is distributed via the LLC system to two Wärtsilä main azimuth steerable thrusters aft, and two tunnel thrusters forward. The design service speed is 15.0 knots.

The 'Harvey Energy', an offshore supply vessel for New Orleans headquartered Harvey Gulf International Marine, will be the first to have one of these engines; a breakthrough entrance for Wärtsilä into the huge North American offshore market.
"The Wärtsilä 34DF is the first dual-fuel engine fulfilling the EPA requirements and this is a very important statutory recognition of Wärtsilä dual-fuel technology," says Andrea Bochicchio, Director, Product Management & Engineering, Product Centre 4-stroke, Wärtsilä PowerTech.

Wärtsilä announce that four sister vessels will shortly be supplied with the same Wärtsilä engines, thus further demonstrating both the viability of liquefied natural gas (LNG) as a marine fuel and its growing popularity among ship owners and operators. LNG fuelled vessels offer compelling operational cost savings and significant environmental benefits.
The switch to LNG propulsion is part of Harvey Gulf’s ‘Going Green’ initiative, aimed at reducing the environmental impact of the company’s vessels and operations. “These PSVs will be the cleanest burning vessels operating in the Gulf of Mexico,” says Chad Verret, Senior Vice President, Harvey Gulf International Marine.
