Guinness record holder Wärtsilä 31 to power new fishing vessel
The Wärtsilä 31 engine was recognised by Guinness World Records as being the world's most efficient 4-stroke diesel engine.
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.
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. ■
