Wärtsilä to power first LNG-fuelled PSVs for COSL

Wärtsilä announced the contract to supply 40 Wärtsilä 20DF dual-fuel engines for 12 new LNG-fuelled platform supply vessels (PSVs), which are the first such vessels to be built for China Oilfield Services Co Ltd (COSL).

Wärtsilä 20DF engine offers high fuel efficiency, low operating costs and good environmental performance, as well as its low-load operating ability and proven reliability and durability.

“Efficiency and environmental sustainability are key pillars of Wärtsilä’s approach to creating customer value. The choice of the Wärtsilä 20DF dual-fuelled engine for this major project reflects these values, and we are proud to maintain our leading position in this market by being selected for China’s first LNG fuelled PSVs,” said Henrik Wilhelms, segment sales director, Wärtsilä Marine.


Liu Hui, manager of COSL Shipping’s shipbuilding project management team said that more and more ships are being built for use with LNG fuel, and we see these 12 ships as part of a trend that will continue to grow, and that was why we the company chose Wärtsilä.

The vessels are being built at China’s Wuchang Shipbuilding Heavy Industry. The 40 sets of Wärtsilä engines are scheduled to be delivered to the shipyard at the end of 2019.
