51/60DF engines pass factory acceptance tests

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.These first 51/60DF engines for marine application will power the world’s largest liquefied natural gas (LNG) carrier with electric propulsion based on dual-fuel engines.

Announced in 2006, MAN Diesel’s 51/60DF dual-fuel engine is based on the well-proven 48/60B heavy fuel engine and offers a 1,000 kW cylinder output in both gaseous and liquid fuel operating modes.
