Danish naval design and marine consultancy, Knud E. Hansen A/S, has developed a 50m factory trawler with a focus on operating efficiency and maximised catch processing facilities.
The design is said to deliver excellent fuel economy, reduced environmental impact, and the flexibility to be operated as a single or pair trawler.
Standards of safety, working- and living conditions, together with the need to allow reasonable space for processing catch onboard, have led to an optimal ship length of at least 50m.
The trawler is designed with two continuous decks for a fluid workflow plus one partly open boat deck and a forecastle deck. The superstructure is three decks high and is positioned forward of amidships.
The fish hold and engine room together with bunker tanks are placed below the first deck.
The entire first deck, apart from engine casings aft, is dedicated for fish processing and quick freezing - some 300m2 of customisable space.
The second deck is the trawl deck and has double trawl lanes running the entire ship length with casings at each side forward containing accommodation and trawl-shops.
On the boat deck behind the superstructure is space for winches, cranes and lifesaving equipment.
The hull is designed with a bow shape optimised for efficient operation in all sea states and at all draughts while trawling. The propulsion system has been designed with a focus on energy efficiency and consists of two low-speed large-diameter propellers in nozzles optimised for trawling speed. An efficient single propeller solution can also be achieved if desired by the operator.
The ship is constructed to meet the DNV-SILANT-F requirements and as low noise radiation into the sea generally results in better catch it, thereby lowers the fuel consumption and greenhouse gas emission per unit catch.
The trawler can be configured to operate both as a single trawler and as a pair trawler. If intended for pair trawling only, a lower installed power and a reduction in the number of winches and trawling equipment is possible.
