Engines & generating sets - 
the highest efficiency for marine applications

Wärtsilä is continuously developing its portfolio of gas and multi-fuel engines to suit different marine applications, be that offshore oil and gas installations where gaseous fuel is available from the process, or a merchant vessel operating in environmentally sensitive areas. The Wärtsilä engines offer high efficiency, low exhaust gas emissions and safe operation. The innovative multi-fuel technology allows the flexibility to choose between gas and liquid fuel. When necessary, the engines are capable of switching from one fuel to the other without any interruption in power generation.

The design of the Wärtsilä engine range is based on the vast amount of knowledge accumulated over years of successful operation. Robust engines derived from pioneering heavy fuel technology have been engineered to provide unquestionable benefits for the owners and operators of Wärtsilä engines and generating sets.
