Wärtsilä has been awarded the contract to provide the propulsion machinery for a new purse seine fishing trawler ordered by Strand Senior AS, a subsidiary of Strand Havfiske AS based in Norway.
In specifying that an innovative and highly efficient vessel was required, the owners specifically emphasised that the propulsion system should be centred on the Wärtsilä 31 engine. Guinness World Records has listed the Wärtsilä 31 as being the world’s most efficient 4-stroke diesel engine. The best-in-class fuel efficiency of this engine means also that the exhaust emissions are correspondingly minimised.
Wärtsilä will also supply controllable pitch propellers, a 2-speed gearbox, the HP-Nozzle, shaft generator, and the Wärtsilä’s ProTouch control system. The Wärtsilä 2-speed gear solution provides additional fuel savings by enabling the propeller to be operated at low speed when maximum vessel speed or thrust is not required. It also results in reduced noise levels, which is important both for crew comfort and because the level of underwater radiated noise affects the efficiency of the fishing activities.
