Duel-Fuel Engine Ready for Market
MAN Diesel’s type 51/60DF four-stroke, medium speed dual-fuel gas engine has passed the final landmark on its way to its first commercial applications in the marine sector. Having gained type approval in autumn 2007 on the seven cylinder prototype engine in the presence of eight major classification societies, the first production versions of the 51/60DF recently completed their factory acceptance tests (FAT) at MAN Diesel’s Augsburg works. The FATs were witnessed by representatives from shipyard STX of Korea, ship owner EN Elcano of Spain and classification society Bureau Veritas.
The first 51/60DF engines for marine application will power what is reproted as the world’s largest liquefied natural gas (LNG) carrier with electric propulsion based on dual-fuel engines. The new vessel will have an LNG capacity of 174 000 cubic metres and its propulsion and onboard electrical power system follows MAN Diesel’s diesel-electric concept.
MAN Diesel states that testing of the five engines went smoothly. All planned operations were completed on time within a tight schedule to the full satisfaction of the yard, the ship owner and the Classification Society. The engines are now on their way from Germany to STX Shipbuilding in Korea.
