X72DF-M-1.0

X72DF-M-1.0

Designed for, Suezmax tankers, Panamax and Sub-Panamax containers and Capesize bulkers

This 720mm bore engine has the output in the 10,600 to 31,360kW range, and it comes in 5–8 cylinder configurations.

X-DF for methanol and ethanol WinGD’s methanol-fuelled engines can now be adapted and certified for ethanol fuel, with the first ethanol fuelled vessels expected to enter service in 2027.

With the first methanol-fuelled engines delivered in 2025 and the first ethanol-fuelled engines available for order now, X-DF-M/E enables deep-sea ship owners and operators to choose from a range of fuels including carbon-neutral green methanol and attractively priced bio-ethanol.
