Replacing an older vessel built at the same yard in 2012, Karstensens Skibsværft has delivered the new Havsnurp to fishing company Havsnurp AS, owned by the Stølen and Hole families from Midsund in Norway.
This versatile new vessel is designed to target mackerel and herring, as well as industrial species and some whitefish. This is very much a family operation, with the fishing company established in 1985 by brothers-in-law Karsten Stølen and Kjell Inge Hole, who since have taken a step back from running the business they started, to allow the younger generation of Jan Andre and Tor Inge Stølen, and Ken-Arve and Oddbjørn Hole to manage the new Havsnurp’s operations.
The decision to go back to the Skagen yard was a logical one, as Havsnurp AS and Karstensen have worked together since the previous Havsnurp was delivered thirteen years ago.
The 69.99-metre Havsnurp has a 14.80-metre beam and has a carrying capacity of 1951 cubic metres in its nine RSW tanks. The order for the new vessel was placed in the summer of 2021 and the hull was built at the Karstensen yard in Poland before being brought to Skagen for outfitting and sea trials ahead of delivery.
Built to operate as a combination pelagic trawler/purse seiner, Havsnurp’s owners went to MacGregor for the Rapp electric trawl winch system fish pumps, and the Triplex purse seine installation.
The deck is laid out with a pair of 80-tonne trawl winches and in addition to a package of smaller winches, Havsnurp has a pair of 80-tonne side-by-side net drums lined up with the aft gates for deploying and retrieving fishing gear. The purse seine installation has an electric Triplex 1020 hauler, with an NK-6000 intermediate roller crane, FLH-112 corkline stacker and GLH-112 leadline stacker. The 37.70-tonnes purse winches are from Rapp.
Triplex also supplies the KNR-75 crane mounted on the aft gallows and the KN-50 foredeck and fish pump cranes. Pumps are a pair of electric 24-inch units, with the associated power cable and fish hose reels for the stern and starboard side pumping stations.
Catches pass via dewatering on the enclosed cargo deck to the RSW manifold and to the selected tanks, chilled by the double PTG FrioNordica, 2x1300kW/2×1,118,000kCal/h RSW system. C-Flow supplied the vacuum system with twin 4200 litre tanks.
A processing area for whitefish has been supplied and outfitted by Boa Tech, with a pair of KM Fish mk5 gutting machines from Carsoe and a Kapp, Optim-ice BP-140 + T-4000 (107kW/92,000kCal/h) slurry ice system.
Havsnurp’s propulsion arrangement is envisaged for the 4640kW Wartsila 8L32E2 main engine to be able to supply the energy needs for both the 4500mm diameter 4G1005 propeller and the deck, on the principle that when fishing and the electric winches are in continuous operation, the 2500kW Cummins AvK shaft generator mounted on the PTO of the Wartsila SVC95-P58 reduction gear is clutched in. The design thinking is that when the winches demand full power, there’s a lower propulsion requirement, so the three 605kWe Nogva Scania DI16 auxiliaries won’t need to be run under normal circumstances.
In the event of a demand for additional power, the auxiliary engines are capable of running the ship’s normal power supply including the load on the winch system. The power management system on board monitors energy consumption and starts and shuts down the auxiliary engines automatically as required.
Havsnurp also has a 1100A shore current connection, making it possible to discharge without the use of diesel generators, although this shore infrastructure is not yet widely available.
