The Scottish pelagic partnership that has taken delivery of new vessel Artemis started out fishing in 2020 with the former Resolute – the 64-metre pelagic trawler renamed Artemis – while its new vessel was under construction by Karstensens Skibsværft in Skagen.
Behind the partnership are Interfish subsidiary Northbay Fishing Company and the Wiseman Fishing Company, headed by Scottish Pelagic Fishermen’s Association (SPFA) chairman Alex Wiseman, whose son Adam is skipper of the new vessel.
The design, specifications and arrangements finalised in co-operation with the yard’s designers to achieve optimum standards for the crew, the best possible catch-handling and storage, and optimised performance and fuel consumption. To achieve these aims, there’s nothing but the best to be found in the range of systems and equipment onboard Artemis.
Artemis’ hull was built at the Karstensen Shipyard, Poland, and arrived in Skagen in February 2022 for outfitting. It headed straight for fishing grounds following delivery to make a start on herring.
The 75.7-metre LOA, 15.6-metre beam vessel has an energy and propulsion arrangement designed on similar lines to other recent Karstensen newbuilds, with a two-step gearbox and options for diesel-mechanical and diesel-electric operation, which on sea trials returned a 16.8-knot top speed at step one and 15.4 knots at step two, and 12.1 knots in diesel-electric mode.
Tried and tested
Its layout has a Wärtsilä package of a 6100kW 10V31 main engine driving a 4,200mm diameter 4G1095 propeller via a SCV 100/2-PDC68 gearbox coupled to a Marelli MJRM 710 2800kW/3500kVA shaft generator. The 866kW, W12V14 auxiliaries are also Wärtsilä units and the harbour set is a 200kWe Scania DI09.
This tried-and-tested configuration works on the basis of when the winches demand full power, there’s less demand from propulsion. The gearbox PTO is clutched in while the winch system is in use, with power routed from the shaft alternator to give the deck all the power it needs. Once the gear is back in the water and Artemis is towing, the PTO can be clutched out, power routed to the shaft from the main engine and electrical power to the systems on board comes from one of the two gensets.
The gensets are able to connect into main switchboard, controlled by the vessel’s DEIF power management system. Its electrical power system is designed for sliding frequency (60-50Hz), by means of frequency converters for 400/440V and rotating frequency converter for 230V. This allows main engine and propeller revs to be 17% lower than would otherwise be possible.
An additional feature is a clutch between main engine and gearbox. In the event of a main engine failure, a separate pony motor allows the shaft generator to start up as an electric motor, being fed off the auxiliary engines and providing a take-me-home option. Up to 1,500kW can be used for this diesel-electrical propulsion drive.
Artemis has a Kongsberg high lift flap rudder and Tenfjord SR 622 steering gear, and the thrusters are 950kW Brunvoll FU-63 units.
Crew comfort
Keeping the crew comfortable was high on the owners’ list of priorities and accommodation onboard is located as far as is practical from the propeller to minimise noise levels, with six single cabins for crew and engineers at main deck level, and four single cabins, sick bay, steam bath, oilskins and changing rooms, and coffee bar in the superstructure.
One deck up is the day room, mess room, coffee bar, galley and provision room, plus separate fridge and freezer spaces, and there are three single officer’s cabins on the next deck, along with the trim room and instrument room. All cabins are outfitted with en-suite facilities.
Artemis has a 2,313-cubic metre capacity in its 12 RSW tanks. A pair of 20-inch SeaQuest fish pumps are deployed from the fish pump deck and catches are routed to the separator and from there to the selected tanks. The owners opted for a twin Johnson Controls 1400kW/1.204.000kCal/h RSW system with a C-Flow vacuum system for discharging.
The trawl deck layout has a Karmøy Winch package, with a pair of 91-tonne trawl winches controlled by a Karmøy Winch management system. There are 110-tonne net drums in a waterfall configuration, aligned to the stern gates equipped with hydraulic closers and guiding pics, a 71-tonne topline winch and a 57-tonne tail-end winch, as well as mooring winches, an anchor windlass, a netsounder winch on the aft gallows and two sets each of hydraulic and fish hose reels for the SeaQuest fish pumps. A net bin on the starboard side is recessed into the shelterdeck.
The deck cranes are from MacGregor Triplex, with a KN-60 fore deck crane, an NK-6000 net crane aft and a KNR-75 fish pump/general purpose crane mounted on the aft gantry with a deployment area over the trawl deck and aft of the stern.
Onboard tech
The wheelhouse on board Artemis is fitted out with a heavyweight package of electronics, supplied by Echomaster Marine and Furuno and installed by KS Elektro.
The Furuno Smart Bridge puts a row of five 55-inch Olorin monitors facing the skipper’s control position and there are a further 15 27-inch Hatteland monitors placed around the wheelhouse.
The echo sounders are a Furuno FSS-3 BB and a pair of Simrad ES80 sets, and the key fishfinding sonars are all from Simrad, with a low frequency 14-19-24kHz ST94 set, a medium frequency 70-85-90kHz CS-94 and an FS-70 trawl sonar. The bow scanner is a Simrad SN90 and the net monitoring system is a Marport package of gear-mounted sensors from doors to codend.
Plotters are an Olex 3D set and a pair of MaxSea Time Zeros, in addition to a Furuno FMD-3200 ECDIS unit. The CI68 current indicator are from Furuno, as are the 3210 and 3230 radars. The A3 GMDSS setup, V-Sat, SatTV and VHF sets are all from Sailor.
