About Wärtsilä
Wärtsilä is a Finnish company founded in 1834. The company is headquartered in Helsinki, Finland and has developed a major international presence in marine and energy technologies.
Wärtsilä marine engines are used for main propulsion, auxiliary power and onboard electricity generation across a wide range of commercial vessels.
The installed marine engine base includes diesel, gas, dual-fuel and newer alternative-fuel engine platforms, as well as earlier Wärtsilä and Vasa engine families that continue operating worldwide.
Because Wärtsilä engines can differ by generation, cylinder configuration, fuel system, rating and application, the complete engine designation and serial number are important when identifying replacement parts.
