Wärtsilä future-proofs stern trawler propulsion

The latest addition to Wärtsilä’s engine portfolio, the Wärtsilä 25 4-stroke engine is a modular system that can easily be upgraded to run on low or zero carbon fuels, as they become available. It is available in diesel and dual-fuel versions and will also be the first 4-stroke ammonia-fuelled marine engine.

“In the competitive fishing industry, costs, reliability, and efficiency are central to everything, and the choice of the Wärtsilä 25 engine caters to these demanding needs,” said Stefan Nysjö, Vice President of Power Supply, Wärtsilä Marine.

“We are excited to extend our long-time relationship with Vardin and to support them in preparing for their transition to alternative fuels in the future.”

The vessel is the first of three newbuilds scheduled for operation in the Faroe Islands. The second two will be jointly owned by Vardin and fellow Faroe Island operator, Framherji, and will also feature the Wärtsilä 25 engine.

The modular, upgradeable design of the Wärtsilä 25 engine will allow Vardin to reduce vessel fuel consumption and emissions from the first mile, while providing the readiness to run on alternative fuels as they become available. All engines will also be fitted with Wärtsilä’s selective catalytic reduction system.

The Wärtsilä 25 is available in cylinder configurations from 6L to 9L and with a power output ranging from 1.7–3.4 MW. Delivery is scheduled for the first quarter of 2025.
