X52-1.1

X52-1.1

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

The compact design with limited engine width and height makes X52 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.
