Order Placed via Wärtsilä Hyundai Engine in Korea
Finland’s Wärtsilä says it’s to supply 54 of its 50DF dual fuel engines, both nine- and 12-cylinder variants, to power Arc 7 design icebreaking liquefied natural gas carriers being built by Daewoo Shipbuilding and Marine Engineering in Korea.
The order was placed with the Wärtsilä Hyundai Engine joint venture in Korea last month.
The ships will be operated by two joint ventures serving the Yamal LNG project in Northern Russia, Wärtsilä says: one between Teekay LNG Partners of Canada and China LNG Shipping, and a second between the China Shipping LNG Investment Company and Japan-based Mitsui O.S.K.
“In arctic waters the engines will be operating in ambient temperatures of as much as minus 50 degrees Celsius on LNG carriers breaking through ice more than two meters thick,” Wärtsilä says, in “modes that allow dramatic variations in engine load within a limited period of time.”
Wärtsilä says that its “ability to meet these demanding design criteria was a key factor in the award of this contract.”
The total power output from the Wärtsilä engines is 64,350 kilowatts per vessel, or approximately 86,300 horsepower.
65% LNG Carrier Market Share
“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,” Wärtsilä Ship Power VP Lars Anderson said in a release.
“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,” he said.
Wärtsilä says it’s thus far supplied more than 160 ships with its Wärtsilä 50DF machinery.Contact information is only available to premium subscribers. Click here to purchase a premium subscription.
