Future proof dual fuel engines

Wärtsilä dual fuel engines allow ships to be operated on either LNG or conventional liquid marine fuels, including LFO, HFO or liquid biofuel. Using LNG instantly and drastically reduces CO2, NOx, SOx and particulate matter emissions. LNG is also well-established as a maritime fuel around the world, with mature legislation frameworks and robust bunkering infrastructure.

The switch between fuels can be made seamlessly without loss of power or speed. Such fuel flexibility enables compliance with emission regulations in controlled areas, while giving operators the option of determining the fuel according to cost and availability.

Wärtsilä engines are a future-proof investment – whatever fuel the future holds, Wärtsilä’s engines will be able to handle it.
