Daewoo Shipbuilding and Marine Engineering (DSME) yard has chosen Wärtsilä to provide dual-fuel engines for the Yamal LNG project in Northern Russia.
The engines will power 54 172,600 cbm icebreaking LNG carriers which are owned by one joint venture between Teekay LNG Partners of Canada and China LNG Shipping, and another joint venture between China Shipping LNG Investment and Mitsui O.S.K.
For each vessel Wärtsilä will provide 12-cylinder and 9-cylinder 50DF dual-fuel engines, with the total output standing at 64,350 kW per vessel.
Lars Anderson, VP of Wärtsilä Ship Power said the order was an important one as it emphasised the company’s technical leadership. “The fitting of Wärtsilä 50DF engines onboard the first LNG carriers in 2006 set a trend in the industry and since that introduction, 65 percent of all new LNG carriers have been fitted with Wärtsilä dual-fuel engines. The strong success of this particular engine over the alternatives is based on its superior propulsion efficiency and the clear environmental advantages that operating on gas allows”.
The Wärtsilä 50DF engine is capable of operating on LNG, HFO or MDO and in arctic waters where the ambient temperatures can be as much as minus 50 degrees celcius on LNG carriers breaking through ice more than two metres thick.
