The latest vessel to join the Norwegian pelagic fleet is Havfisk, delivered by the Karstensen yard in Skagen on a hull fabricated by the Karstensen Shipyard Poland in Gdansk.
Havfisk is the outcome of a long cooperation between the Karstensen yard and Henning Veibust of Veibust Fiskeriselskap, which operates three pelagic vessels. This began when Havstål came to the yard for an extensive conversion job, after which the order was placed in 2021 for Havskjer.
New Havfisk shares the same basic design principles with Havskjer and the owners didn’t have to think too hard before taking this order to Karstensen.
The operating pattern is to trawl for blue whiting, and to focus on purse seining for mackerel and herring. Havfisk is the yard’s own design and the latest in a long series of pelagic vessels for fishing operators around the Northeast Atlantic region. In this case, Veibust was keen to incorporate innovations, and the design aims to optimise working conditions, safety and crew comfort – as can be seen from the outfitting that wouldn’t look out of place in a top rank hotel.
Havfisk has an overall length of 75.1 metres with a 16.2-metre moulded breadth and 2,530-cubic-metre capacity in its 11 RSW tanks. Catches are pumped on board and routed via the dewatering box to the central manifold and from there to the selected tanks. PTG FrioNordica supplied the double 1500kW/1,290,000kCal/h RSW system and the vacuum pump configuration is a C-Flow system with twin 4200-litre tanks.
Tailored layouts
The deck is laid out with Karmøy Winch hardware. The trawl winches are a pair of 90-tonne units managed by a Karm autotrawl system and Havfiskleft Skagen with a fully controllable pair of Thyborøn TYPE 42 Bluestream doors hung on the stern. The two 148-tonne net drums are laid out in a waterfall configuration aligned to the stern gate with hydraulic control rods to deploy and retrieve the trawl gear.
The trawl layout is offset slightly to port and the recessed net bin for the purse seine is on the starboard side. Karmøy Winch supplied the 40-tonne Tristar Giant hauler on the starboard side, and an array of gear handling hardware with net crane fitted with a transport roller and reach over the aft deck, as well as corkline and leadline stackers.
There are two 20-inch Karm fish pumps, with a pump crane aft for handling trawl catches and a forward crane for pumping out the purse seine, as well as the associated hose and hydraulic reels. The installation includes a complete high-pressure hydraulic system to power the winches, cranes and fish pumps, with a package of twelve 158, 110 and 87kW power packs.
Havfisk has a complete Wärtsilä propulsion system with a 5200kW 8V31 main engine driving a 4200mm diameter 4G1005 propeller via a SCV 95-PDC58, 750/130rpm reduction gearbox, also powering the 3400 kW/4250 kVA shaft generator. This provides all the power needed for purse seining. In addition, there are three 600kWe Nogva Scania DI 16 auxiliary engines. The electrical system is designed to enable parallel operation of the three diesel generators and comes with a Power Management System that manages power consumption and automatic genset start-up.
On sea trials Havfisk achieved 16.4 knots in diesel-mechanical mode and 11.7 knots using diesel-electric propulsion.
The steering gear and high-lift flap rudder are from Kongsberg and the 1400kW FU-74-LTC-2000 thrusters are from Brunvoll.
Furuno fishfinders
Havfisk’s wheelhouse is laid out with three NorSap 1600 chairs facing the bank of screens of the Furuno Blue Bridge system, and a fourth at the aft wheelhouse winch control position overlooking the deck.
The big fishfinders are the three Furuno sonar, a low frequency FSV-25, a medium frequency FSV-75 and a high-frequency FSV-85, plus Havfisk has a pair of Furuno Imagenex TS-332 trawl sonars. The echo sounders are Furuno FCV-38, FCV-1900 and DFF3/DFF1, units, as well as a Simrad ES80. The log is a Furuno CI-68.
Plotters are a pair of MaxSea Time Zero sets and an Olex, in addition to which Havfisk has two Tecdis T-2138A Ecdis sets.
Radars and the satellite compasses are Furuno sets and Simrad supplied the gyro compass and autopilots.
Communications systems are Sailor VHF sets, and the satellite phones are Thrane Iridium LT-3100 units. Satcoms are handled by the Sailor-900 Ka/Telenor and the two StarLink/Florvaag systems. The satellite TV system on board is from Furuno Norge.
Havfisk’s thermal imaging camera is a Flir M625CS with gyro stabilisation.
