Wärtsilä dual-fuel engines to power icebreaking LNG carriers
Daewoo Shipbuilding and Marine Engineering’s (DSME) shipyard in South Korea has ordered a total of 54 Wärtsilä dual-fuel engines to power 172,600 m3 icebreaking LNG carriers.
The carriers are being built for use in arctic conditions to serve the Yamal LNG project in Northern Russia.
The ships will be owned by one joint venture between Teekay LNG Partners of Canada and China LNG Shipping (CLNG), and another joint venture between China Shipping LNG Investment Co. Ltd. (CSLNG) and Japan based Mitsui O.S.K. The order for engines was placed with Wärtsilä's Korean joint venture company, Wärtsilä Hyundai Engine Co., (WHEC) in October.
Dual-fuel capability
The Wärtsilä engines are capable of operating on LNG, heavy fuel oil (HFO), or low-viscosity marine diesel oil (MDO) however LNG will be the main fuel type to be used. When operating in arctic waters the engines will be operating in ambient temperatures of as much as -50 degrees Celsius on LNG carriers breaking through ice more than 2 m thick.
For each LNG carrier Wärtsilä will supply 12-cylinder and 9-cylinder Wärtsilä 50DF dual-fuel engines. The total power output from the Wärtsilä engines is 64,350 kW per vessel.
Comments
Commenting on the award, Lars Anderson, Vice President, Wärtsilä Ship Power, said: "This very important order once again emphasises the technical leadership that Wärtsilä has established in dual-fuel engine technology. The fitting of Wärtsilä 50DF engines onboard the first LNG carriers in 2006 set a trend in the industry and since that introduction, 65% 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."
Wärtsilä has to date supplied more than 160 ships with its Wärtsilä 50DF machinery.
