For their new pelagic vessel, the Norwegian owners of Herøyhav returned to the Karstensen yard in Skagen, which had delivered the previous vessel of the same name back in 2013.
Built to the Karstensen yard’s own 75-metre, 16-metre breadth design and with a 2500 cubic metre RSW tank capacity, Herøyhav is the latest in a series of new pelagic vessels for fishing companies around the north-east Atlantic.
Herøyhav has been built for owners Ronald Ervik, who also sails as skipper, as well as siblings Gunn and Espen, and Rolf Jarle Ervik. The steelwork was completed at the Karstensen Shipyard Poland in Gdansk and the hull was brought to the yard in Skagen for oufitting – and the handover at the beginning of July before Herøyhav sailed for Norway.
It’s designed to operate on conventional lines, fishing with pelagic trawl gear for blue whiting on deep water grounds, and with options to fish for herring and mackerel with either trawl or purse seine gear. The design process has been conducted in close collaboration, with Ronald Ervik and Marianne Vangsnes spending a great deal of time at the yard during outfitting.
Herøyhav has eleven RSW tanks, providing a total of 2500 cubic metres of carrying capacity, chilled to maintain catches in peak condition with a double PTG FrioNordica 2 x 1500 kW RSW system. C-Flow delivered the vacuum system with its twin 4200-litre tanks.
The deck is laid out with a pair of net drums offset to port and aligned to the hydraulic stern gate with three hydraulic control pins, while the recessed net bin for the purse seine gear is on the starboard side.
Herøyhav’s owners went to Evotec for the electric trawl winches package, while cranes and purse seine handling systems are from Storm Cranes and SeaQuest Systems supplied the two 20-inch fish pumps, each with a power cable drum and a hose reel.
The trawl winches are 70-tonne units, controlled via a Scantrol/Evotec autotrawl. The pair of net drums each have a 97-tonne pull. Evotec also supplied the 40-tonne tail-end winch, net sounder winch and an array of smaller winches, including the 39-tonne purse winches.
For purse seining, the Storm net hauler is a NH 1030-600 EL unit with a 40-tonne pull. Storm Cranes also supplied the NC-600 intermediate roller crane and the KB-1000R net crane, as well as the corkline and leadline stackers. The package also includes a KB-800 foredeck crane and a KB-600 fish pump crane.
The energy setup on board Herøyhav is tailored to suit its operating pattern, with a Wärtsilä package of 5200kW 8V31 main engine driving a 4200mm 4G1005 propeller via a two-step (750/130rpm) SCV 95-PDC58 reduction gearbox, also powering a water-cooled Marelli 3400kW/4250kVa shaft generator.
This is designed to provide all the power needed when purse seining, including running the 1400kW Brunvoll FU-74-LTC-2000 thrusters. For trawling, this meets propulsion requirements, and additional power can be derived when required from the two 940Kw and one 550kw Caterpillar auxiliary engines, which are arranged for parallel operation.
Accommodation on board is on four cabins at main deck level, and a further four plus a sick bay within the superstructure. Boat deck one has five officer cabins, and the dayroom, cinema mess and galley are on boat deck two. Placing crew areas as far as possible from the propeller and other sound sources, plus a number of constructive noise insulation measures ensure that noise levels are kept well below required limits.
