KNESTER - the latest large Norwegian pursermid-water trawler delivered by Eidsvik Skipsbyggeri - is based on a new design from Rolls-Royce NVC.

Monrad Hide of RollsRoyce NVC tells FNI that the company's NVC 352 design for the 71.10 x 14.40 metre Knester is a breakthrough in the large purse seiner sector.

The ship has been built for Norwegian owner Knester AS of Austevoll.

According to Monrad Hide, her hull design is the result of long-term development based on model tests carried out by Ship Technology - Fish.

"She has a brand new, low resistant, hull to cope with the increasing demand for high speed and fuel saving capabilities, combined with good seakeeping characteristics.

"The aft ship with propeller is also optimised in order to provide optimum towing power during trawling.

Efforts have been made to limit noise levels on board, and this gives better working conditions and comfort for the ship's crew.

"The highest attention has been paid to designing a real working machine to attend to the demands of increased efficiency and the importance of safe working conditions during both purse seining and pelagic trawl operations.

"A new arrangement for her tank/refrigerated sea water (RSW) system copes with the demand for increased capacity per hour, as well as the importance of the highest quality of the catch."

FNI is told Knester has a two-speed main propulsion system to focus on reduced fuel consumption, as well as noise reduction both into the water and into the ship.

She has a 2000 cu.metre RSW capacity for chilling mackerel, herring, capelin and blue whiting caught in the North Sea, Atlantic, Barents Sea and the maritime zones around Iceland and Greenland.

Rolls-Royce NVC designed the new pelagic ship for completion at Eidsvik on a hull delivered by a yard in Eastern Europe. She is equipped with separate deck equipment for trawling and for purse seining.

Her skipper has a 360infinity view from the wheelhouse thanks to a new bridge layout with standalone consoles and submerged chart units have been installed.

Her accommodation - including a dayroom and a new designed bridge - ensures a high standard of facilities and comfort for her 12-man crew.
