Teekay LNG Partners L.P. (Teekay LNG), which operates in the LNG and LPG shipping sectors, has entered into an agreement with Daewoo Shipbuilding & Marine Engineering CO., LTD., (DSME) of South Korea for the construction of two 173,400 m3 Liquefied Natural Gas (LNG) carrier newbuildings. The vessels will be constructed with MAN Diesel & Turbo dual-fuel, two-stroke, gas injection engines.
The order is MAN Diesel & Turbo’s second for the MAN B&W ME-GI dual-fuel, two-stroke, gas-injection engine. The ships will each by powered by two 5G70ME-GI engines. The order includes an option for three further ships.
Peter Evensen, Chief Executive Officer of Teekay GP LLC said: “The newbuildings will be constructed with M-type, Electronically Controlled, Gas Injection (ME-GI) twin engines, which are expected to be significantly more fuel-efficient and have lower emission levels than other engines currently being utilized in LNG shipping.”
He continued: “MAN’s ME-GI engine is highly suited to the LNG carrier market and is recognized as the most fuel-efficient gas-burning engine on the market. We are confident that the quality and fuel-efficiency of these engines will be very attractive to our customers.”
The Teekay LNG engines are based on the new ultra-long-stroke G-type concept to deliver an even higher overall propulsion plant efficiency.
The Teekay order follows TOTE’s order at NASSCO for two 3,100 TEU newbuilding LNG-fuelled container ships, each powered by an 8L70ME-GI engine, with an option for three additional vessels.
Ole Grøne, Senior Vice President Low-Speed Sales and Promotions, MAN Diesel & Turbo, said: “With the current flux in fuel prices, and the new Environmental Control Areas (ECAs), we felt the timing for the release of a commercial, low-speed, dual-fuel engine was right.”
The ME-GI uses high-pressure gas injection that allows it to maintain the numerous positive attributes of the low-speed engine that have made it the default choice of the maritime community. The ME-GI dispenses with the need for power derating and eliminates the significant problem of methane slip (and resulting CO2 emissions).
