A total of 30 Wärtsilä 50DF dual-fuel engines will power five Arc 7 design ice-class LNG carriers being built by Daewoo Shipbuilding and Marine Engineering (DSME) in South Korea.
The vessels will operate in arctic conditions, serving the Yamal LNG project in Russia. The order was placed in January with Wärtsilä Hyundai Engine Co. (WHEC), who will build the engines in South Korea.
Arctic conditions
Each LNG carrier will be fitted with four 12-cylinder Wärtsilä 50DF engines and two 9-cylinder Wärtsilä 50DF engines. The engines will primarily LNG as fuel, but are also capable of running on conventional marine diesel fuels. When operating in arctic conditions, the vessels will be required to handle temperatures as low as -50°C, and to break through ice up to 2 m thick.
"Altogether, Wärtsilä has been contracted within the past twelve months to supply 90 dual-fuel engines to fifteen of these Arc 7 ice-class LNG carriers for the Yamal project. This is a clear endorsement of the very high efficiency and reliability of the Wärtsilä machinery, which owners and shipyards around the world recognise. It is a pleasure to cooperate with DSME and the vessel owners in meeting the demands of arctic operations," commented Lars Anderson, VP of Wärtsilä Ship Power.
Yamal LNG
The Yamal LNG project is expected to produce 16.5 million tpy of LNG by the end of 2017, for shipment to European, Asian and South American customers.
