Wärtsilä 14

The Wärtsilä 14 is the most compact engine in its power range in the marine market, and serves both propulsion and auxiliary genset applications in the global marine and offshore markets. The engine is an integral element within Wärtsilä’s Smart Marine vision for the future of shipping, whereby optimal efficiency, safety, and environmental sustainability will be the key pillars in achieving and maintaining profitable operations for ship owners and operators around the world.

The Wärtsilä 14 high-speed engine is available in 12- and 16-cylinder configurations, having a power output between 755 and 1340 kWm in mechanical propulsion, and between 675 and 1155 kWe in auxiliary generating set and diesel-electric propulsion applications.


    Wärtsilä 14 is intended for multiple applications within the marine and offshore markets. The Wärtsilä 14 can serve both main propulsion and auxiliary genset applications, and is also well-suited for hybrid installations. The Wärtsilä 14 engine is especially aimed at segments and vessel types where the operating profile, fuel type used, and power to weight ratio better befit high-speed engines. These include for example tugs, small ferries, offshore service vessels, fishing vessels, inland vessels and the merchant auxiliary market.
