X52DF-M-S1.0

X52DF-M-S1.0

The most compact engine in its class of very low shaft speed engines

The compact design with limited engine width and height makes X52DF-M-S1.0 suitable for slim hull lines and the wide rating field offers optimum propeller speed for different application. Thanks to the engine’s agility, it is the optimum choice for several vessel segments e.g. Handymax tankers and bulk carriers or 1000–1800 TEU feeder container vessels.
The X52DF-M-S1.0 engine has a cylinder bore diameter of 520 mm and a piston stroke of 2,045 mm. The engine will be available with five to eight cylinders configuration being able to cover a power range of 4,550-15,280 kW at 80-120 rpm.

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.
