100th Delivery Milestone For Wärtsilä Dual-Fuel Engine

The 100th Wärtsilä 20DF dual-fuel engine is to be delivered this month, 4.5 years after the first one was shipped from the factory.

The 100th milestone delivery comprises three 8-cylinder Wärtsilä 20DF engines for a Ropax ferry for BC Ferries, currently under construction at the Remontow shipyard in Poland. The 100th Wärtsilä 20DF engine is to undergo its Factory Acceptance Test (FAT) within the coming weeks with representatives from BC Ferries in attendance.

The 20DF engine has dual-fuel capabilities, enabling ships to operate on either conventional liquid fuels, such as light fuel oil, heavy fuel oil, and liquid biofuel, or liquefied natural gas (LNG) as an alternative.

When operating in gas mode, the Wärtsilä 20DF engine is compliant with International Maritime Organization (IMO) Tier III regulations without the need for any secondary exhaust gas purification systems. When fuelled by gas, the sulphur oxides (SOx) and CO2 emissions are reduced and smokeless operation is attained.

Stefan Wiik, Vice President, Engines, Wärtsilä Marine Solutions, commented: “Once again, the advantages of Wärtsilä’s dual-fuel technology, and the fuel flexibility and environmental benefits delivered by this technology, have been emphasised with this milestone 100th delivery.”
