New pelagic vessel Havfisk was due to dock in its home port of Ålesund this morning, following the delivery trip from Skagen in Denmark, where the newbuild was completed on a hull fabricated by Karstensen Shipyard Poland in Gdansk.
This new vessel is the latest chapter in a long cooperation between the Karstensen yard and Henning Veibust of Veibust Fiskeriselskap, which operates three pelagic vessels. This began with an extensive conversion job on Havstål, followed by the delivery of the new Havskjer in early 2021. It was a logical next step for the order for Havfisk to come to the same yard, and the new vessel shares the same basic design principles with Havskjer.
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 north-east Atlantic region. In this case Henning 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 75.10 metres with 16.20 metre moulded breadth and 2530 cubic metre capacity in its eleven 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.
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 Havfisk left Skagen with a fully controllable pair of Thyborøn TYPE 42 Bluestream doors hung on the aft gallows. 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 pumpiing 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 16.40 knots in diesel-mechanical mode and 11.70 knots using diesel-electric propulsion.
