The Wärtsilä 31 engine, recognised by Guinness World Records as being the world’s most efficient 4-stroke diesel engine, has been chosen as the main engine for a new purse seiner/trawler being built by the Danish shipbuilder Karstensen Shipyard.

The ship will be owned by Peter Hepsø Rederi AS based in Norway and when completed, this will be the world’s first fishing vessel with the Wärtsilä 31 engine.

“The Wärtsilä 31 engine has established a new benchmark in terms of fuel efficiency, which means also that its overall emissions performance is excellent. We are very pleased to be working with the yard and owners in this project to introduce a world class trawler to the market,” said Aaron Bresnahan, Vice President, Sales, Wärtsilä Marine Solutions.

In addition to the main engine, Wärtsilä will also supply the complete propulsion system comprising a 2-speed gearbox, controllable pitch propellers, nozzle, the Wärtsilä Propulsion Control System, and the shaft generator.

Compared to a single mechanical propulsion system, a fuel consumption reduction of 8% was verified with the Wärtsilä 2-speed gearbox during sea trials. It is anticipated that further reductions of up to 15% can be achieved, with a similar lowering of nitrogen oxide (NOx) and sulphur oxide (SOx) exhaust emissions.

These fuel cost savings and subsequent environmental benefits are achieved when maximum vessel speed or propeller thrust is not required.

Also, by reducing the propeller speed there is a significant reduction in the underwater radiated noise level which is of great importance for fishing vessels and beneficial to marine life in general.

When completed, the 80m long purse seiner/trawler will primarily operate in the North Atlantic, the North Sea and in Norwegian waters.
