MAN sells fuel-sharing engines for LNG carrier
MAN Diesel & Turbo (MAN) says it has won a contract to equip two Greek vessels with a new type of engine that can burn both gaseous and liquid fuels simultaneously, Ship & Bunker reports.
The MAN 51/60DF dual-fuel engines will be installed in two dual-fuel diesel-electrical (DFDE)-driven newbuildings being built for Athens-based Alpha Tankers and Freighters International Ltd.
The installation of the MAN 51/60DF dual-fuel engines on the liquefied natural gas (LNG) carriers is a first for that type of ship, although the concept has already been in use in Man's B&W ME-GI type, a gas-injection two-stroke dual-fuel diesel engine.
The ships will be built at STX Offshore & Shipping Co. Ltd. in South Korea, with the engines scheduled for delivery in the fourth quarter of 2013 and the ships due for completion in 2014 and 2015.
MAN unveiled the ME-GI engine in May 2011, saying that the technology can be combined with exhaust gas recirculation and wasteheat recovery technologies to significantly reduce emissions and meet new regulations.
The company said the use of the fuel-sharing mode in the new LNG carriers will be especially helpful during ballast voyages, when more natural boil-off gas is generated than on laden voyages.
