Trojan Marinex recognized for environmental stewardship JUNE 20, 2016—Invasive species carried in ships’ ballast water are an ongoing threat to local, regional and national economies and ecologies. With more than 90% of the world’s trade being transported by ships, there are an estimated 10 billion tonnes of ballast water being transferred annually. That’s potentially a lot…

TOTE order is first for MAN's LNG-fueled low speed engine

DECEMBER 6, 2012 — The two LNG fueled containerships ordered at NASSCO by TOTE have given MAN Diesel & Turbo its first order for its low-speed, dual-fuel ME-GI engine. The two 3,100 TEU vessels will each be powered by 8L70ME-GI dual-fuel gas-powered engines and will be powered primarily by liquefied natural gas (LNG).

Ole Grøne, Senior Vice President Low-Speed Sales and Promotions, MAN Diesel & Turbo, said: “Our experience with two-stroke, dual-fuel engines stretches back to the 1990s. With the current developments in fuel prices and multiple customer requests for a solution, the momentum towards the development of a commercial, low-speed dual-fuel engine became unstoppable. We see this order as a natural culmination, and see the ME-GI as the beginning of a significant new era.”

Unveiled at a major event at MAN Diesel & Turbo’s Copenhagen Diesel Research Center in May 2011, the ME-GI engine is the culmination of many years’ work that began in the 1990s with the company’s prototype MC-GI dual-fuel engine that entered service at a power plant in Chiba, near Tokyo, Japan in 1994.

Depending on relative price and availability, as well as environmental considerations, the ME-GI engine gives shipowners and operators the option of using either HFO or gas – predominantly natural gas but also, eventually, LPG.

MAN Diesel & Turbo sees significant opportunities arising for gas-fueled tonnage as fuel prices rise and exhaust-emission limits tighten. Indeed, previous research indicates that the ME-GI engine delivers significant reductions in CO2, NOx and SOx emissions. Furthermore, the ME-GI engine has no methane slip, and it is therefore the most environmental friendly technology available.

MAN Diesel & Turbo predicts a broad, potential market for its ME-GI engine, extending from LNG and LPG carriers to other oceangoing vessel segments such as containerships as well as ships plying a fixed trade. It says the ME-GI engine represents a highly efficient, flexible, propulsion-plant solution.
