According to Wärtsilä, the ships are being built for China Oilfield Services Co Ltd (COSL) at the Wuchang Shipbuilding Heavy Industry yard and the Liaonan Shipyard in China.

Wärtsilä will be supplying its 20DF engines, which, the engine maker says, offer “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,” says Henrik Wilhelms, Segment Sales Director, Wärtsilä Marine.

“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. This is why we chose Wärtsilä, a company with experience and know-how in LNG fuel solutions,” says Liu Hui, Manager of COSL Shipping’s Shipbuilding Project Management Team.

The 40 Wärtsilä engines are scheduled to be delivered to the shipyards at the end of 2019.
