New Knud E. Hansen ocean factory trawler design features more efficient hull
A new ocean factory trawler design with hull improvements to the trim, draught and ballast has been released by Knud E. Hansen’s Faroe Islands design team.
The new design includes a high bulbous bow forward and hull shape aft that gives a good flow to the two propellers. The hull is designed for even trim, with the rise of keel built into the keel.
Knud E. Hansen said the classic stern trawler layout has hardly changed since its original design and Marni Olsen and Thormund Johannesen, both master mariner/ senior naval architects at the company explained that “at KNUD E. HANSEN the evaluation of the original design, construction, components and technology led us to conclude that improvements can be made – and are indeed needed.”
Other improvements include a ballast keel that can contain 150t of flow-through seawater ballast; a diesel electric propulsion system consisting of four diesel generators, two electric propulsion engines and two ducted fixed-pitch propellers with almost double the propeller disc area compared to a single propeller design. This is designed to generates high torque and very good efficiency.
Having the engine room laid out on one deck in full length of the ship is expected to significantly improves the practical working conditions for the ocean factory trawler engineer and allows Knud E. Hanens to move the casings for exhaust and ventilation forward. This results in better working area on the trawl-deck aft, said the company.
The increased working areas aft on the trawl-deck allow us to design improvement for the equipment and handling of fishing gear. The traditional gallows and outhauls are replaced with a single hydraulic A-frame on top of the lifted deck. From this position it can, due to the opening in the upper deck over the trawl slip, cover the area from behind the stern to the aft end of the trawl lanes.
The deck area in the cargo hold is more than double the size of the deck area in a traditional trawler layout. This gives a practical working height comparable to the height inside a refrigerated container, improving practical working conditions and safety during fishery and when unloading.
