X82DF-M-1.0

X82DF-M-1.0

The newest two-stroke dual-fuel engine, offering enhanced propulsion options within the VLCC, VLOC and Panamax container vessel segments.

This 820mm bore engine has the output in the 16,560 to 49,500kW range, and it comes in 6–9 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.
