MAN Diesel & Turbo has received type approval from main class societies for its high-speed MAN 175D engine, with a power output of up to 2,200kW for its twelve-cylinder version.

Testing took place on 22-24 May in Frederikshavn in front of representatives from the American Bureau of Shipping, Biro Klasifikasi Indonesia, Bureau Veritas, China Classification Society, DNV GL, the Korean Register, Lloyd’s Register, ClassNK, RINA and Russian Registry of Shipping. MAN Diesel & Turbo reports that the engine performed perfectly, exceeding all class requirements.

The serial approval follows a string of commercial orders last year, in diverse applications both as main propulsion engine and genset. The engine is available with an output ranging from 1,500kW to 2,200kW and is optimised for propelling ferries, offshore supply vessels, tug boats and work boats.

Lex Nijsen, head of four-stroke marine, MAN Diesel & Turbo, said: “The MAN 175D is compact, reliable and efficient – properties that are of essential importance for use on working vessels to allow safe manoeuvrability in the most challenging and rough weather conditions Our long-term aim for this engine is to make it the most efficient engine we’ve ever had throughout its lifetime.”
