The Daewoo Shipbuilding and Marine Engineering (DSME) yard in South Korea has ordered a total of 54 Wärtsilä dual fuel engines to power 172,600 cbm icebreaking LNG carriers 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.

The Wärtsilä machinery is capable of operating on liquefied natural gas (LNG), heavy fuel oil (HFO), or low-viscosity marine diesel oil (MDO) but LNG will be the main type of fuel to be used. When operating 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 metres thick, in operating modes that allow dramatic variations in engine load within a limited period of time. Wärtsilä's ability to meet these demanding design criteria was a key factor in the award of this contract.
