The new 75.40-metre LOA, 16.50-metre breadth Hákon sailed from the Karstensen yard in Skagen in October, and its delivery trip was interrupted with a stopover in the Faroes to deal with an engine problem. It sailed for its first fishing trip almost immediately following its arrival in Reykjavík.
Built to the yard’s own design, and with the hull fabricated at Karstensen Shipyard Poland in Gdansk, Hákon was brought to the Skagen yard for outfitting. The design and layout were finalised in collaboration with the owners to develop a pelagic vessel with a 2500 cubic metre capacity in 13 RSW tanks, and optimised for catch quality and operational economy, as well as for crew comfort.
The deck is laid out with a pair of side-by-side net drums offset to port and lined up to the hydraulic stern gates for handling trawl gear, and a net bin for the purse seine gear on the starboard side.
The full package of deck machinery has been supplied by SeaQuest Systems, with a pair of 91-tonne trawl winches managed by a SeaQuest autotrawl. The two net drums each have an 110-tonne pull and the setup is completed with a 57-tonne tail end winch, a 20-tonne end-wire winch and a netsounder winch mounted on the aft gallows.
The purse winches are 40-tonne units, backed up by a pair of 16-tonne auxiliary purse winches. The purse seine handling arrangement has a 40-tonne nethauler, a netstacker crane mounted on the aft gallows, plus both floatline and groundline stackers. The two fish pumps are 20-inch hydraulic units from SeaQuest, supplied with hose and fish hose reels. Hákon has a 4t/18m crane forward, and a 3.5t/13m crane aft to deploy the fish pump at the stern. SeaQuest also supplied the two complete high-pressure hydraulic drive systems, one for the winches and cranes and the other for the fish pump and associated equipment.
Catches are pumped from the gear to the separator on the foredeck and from there are routed to the selected RSW tank/s.These are chilled using a double PTG FrioNordica system, each of which has a 1300kW/1,118,000kCal/hour capacity, with two 960 cubic metre/hour circulation pumps and two 260 cubic metre/hour condernser pumps. C-Flow supplied the vacuum system with two 4200-litre tanks.
Hákon’s propulsion system is a Wärtsilä package, with a 5200kW 8V31 main engine driving a 4000mm 4G1005 propeller via the SCV95-PDC58 reduction gearbox with a PTO for the Marelli shaft alternator.
While towing, the shaft alternator can be de-clutched and the vessel’s electrical power requirements can be met by the 940kWe and 565kWe Caterpillar gensets which connect to the main switchboard, controlled by the DEIF power management system.
The propulsion arrangement provides the option of a take-me-home system, using a clutch between the main engine and the gearbox, and the shaft generator used as an electric propulsion motor, powered by the two gensets.
