Wärtsilä Ship Design has introduced a new optimised stern trawler design that will reduce fuel consumption and notably increase overall vessel efficiency compared to currently available designs.
The propulsion system is based on the Wärtsilä 31 engine (according to Guinness World Records the world's most efficient 4-stroke diesel engine). The design also incorporates the company's hybrid battery technology, which offers a significant energy efficiency improvement over conventional systems by running the engine at optimal load and absorbing many of the load fluctuations using batteries.
Layout, Hull and Gearbox
The Wärtsilä VS 6215 ST stern trawler design has a new aft ship layout and an optimised hull. In addition to the hybrid battery technology, the design also incorporates Wärtsilä's 2-speed gearbox for further reductions in fuel consumption and emissions. The design of the 82 metre long vessel emphasises sea-keeping and stability. The factory capacity is 80T/24h.
More Profitable Operations
'Stern trawlers can be out fishing for up to 350 days a year and fuel consumption is, therefore, an extremely relevant consideration. Our new design features the very latest technologies, and has been developed to offer the fishing industry lower fuel costs and greater possibilities for profitable operations,' says Riku-Pekka Hägg, Vice President, Ship Design, Wärtsilä Marine Solutions.
The Wärtsilä VS 6215 ST stern trawler design will be a feature of the Wärtsilä stand at the Nor-Fishing 2016 conference and exhibition being held in Trondheim, Norway from August 16 to 19.
