Wärtsilä announce their new medium-speed 46DF engine which is capable of operating on natural gas, heavy fuel oil, or marine diesel oil.

“With this newly launched product, Wärtsilä has raised the industry standard even higher, since it offers simultaneously drastically lower specific fuel consumption, both in gas and diesel fuel mode, remarkably higher output, and extremely attractive lifecycle costs compared to any other alternative currently available on the market,” says Mr Lars Anderson, Vice President 4-stroke Sales, Wärtsilä Ship Power.

The engine builders explain that the fuel flexible Wärtsilä 46DF engine has been specifically developed for the high-output market segment, including cruise ships and ferries, merchant vessels, LNG carriers and FSRUs (Floating Storage and Regasification Unit), and offshore vessels and platforms, and is capable of operating on natural gas, heavy fuel oil, or marine diesel oil. This fuel flexibility enables reduced operational expenses, compliance with the most stringent emission standards, and full redundancy to ensure uninterrupted operation.

The Wärtsilä 46DF consists of two different versions to meet specific customer needs. The high efficiency version offers drastically lower fuel consumption with a cylinder power of 1045kW, while the high power version is capable of a cylinder power of 1145kW with excellent engine thermal efficiency. For LNG carrier applications, the Wärtsilä 46DF can offer fuel savings of as much as 20 tons/day compared to the first introduced DF engines. With up to 14 fewer cylinders installed, the overall lifecycle installation costs are significantly and positively impacted by roughly 1000 USD/day.

When operating in gas mode, the Wärtsilä 46DF engine is already compliant with IMO Tier III regulations without any secondary exhaust gas purification systems. When fuelled by gas, the sulphur oxide (SOx) and carbon dioxide (CO2) emissions are notably reduced, and smokeless operation is attained. In liquid fuel oil mode, the Wärtsilä dual-fuel engines are fully compliant with the IMO Tier II exhaust emission regulations set out in Annex VI of the MARPOL 73/78 convention.
