Daewoo Shipbuilding and Marine Engineering (DSME) has ordered a total of 54 dual-fuel engines to power the icebreaking LNG carriers being built for use in arctic conditions to serve the Yamal LNG project in Northern Russia.
The 172,600m3 ships will be owned by two different joint ventures, a partnership between Teekay LNG Partners and China LNG Shipping (CLNG), and a joint venture between China Shipping LNG Investment (CSLNG) and Mitsui OSK.
The machinery is capable of operating on liquefied natural gas (LNG), heavy fuel oil, or low-viscosity marine diesel oil. However, LNG will be the main type of fuel used.
When operating in arctic waters, the engines will be operating in temperatures as cold as -50 degrees Celsius, with the vessels capable of breaking ice more than two metres thick.
Each vessel will have a total engine output of 64,350kW, and will be capable of operating in modes permitting variations in engine load within a limited period of time.
