MAN dual-fuel engines hit million-hours milestone

MAN Energy Solutions’ portfolio of two-stroke, dual-fuel engines, running on clean fuels such as LNG, LPG, ethane and methanol, has hit a milestone accumulating 1 million operating hours.

The milestone comes on the back of the 300 engines/6.3 GW sales the company recently reached for the segment, MAN E&S said in its statement

MAN Energy Solutions’ ME-GI (-gas injection) and ME-LGI (-liquid gas injection) engines form the core of its two-stroke, dual-fuel portfolio and have notched a number of industry-firsts since their market introduction, including the very first oceangoing ships operating respectively on LNG, methanol, ethane and LPG, the statement reads.

Bjarne Foldager, senior vice president, head of two-stroke business at MAN Energy Solutions, said “Our plan is very much to continue this dual-fuel focus. To this end, we recently released a Mk II ME-GI model and are currently, owing to market demand, developing an Otto-cycle variant – the ME-GA.”

The company noted that in gas mode the Mk II engine significantly reduces pilot-oil consumption, through the use of a PBVI (Pilot Booster Injection Valve), to just 1.5 percent, approximately half of what was previously required.

With fuel prices and availability currently in flux, MAN Energy Solutions expects the choice of retrofitting to dual-fuel engines to ultimately become a necessity.
