The Wärtsilä 50DF dual-fuel engine represents a pioneering industry change from traditional steam turbine machinery to a dual-fuel-electric concept with the benefits of much better operating economy and lower exhaust emissions. The engine can run on either natural gas, marine diesel oil (MDO) or on heavy fuel oil (HFO). Furthermore, the engine can smoothly switch between fuels during engine operation and is designed to give the same output regardless of the fuel used.
