The hull is built in steel with two continuous decks; main deck and shelter deck, and with long forecastle- and boat decks. Wheelhouse, boat deck 02, funnel and masts are built in aluminium.
Hull shape is of round bilge construction with bulbous bow and stern skeg, flared stem and transom stern.
Below main deck the hull is subdivided into the following watertight compartments: Forepeak, sonar room, thruster room (retractable thruster), insulated RSW-tank section with central RSW pump- and manifold room, engine room with main engine connected to one reduction gearbox with one, ducted propeller and aftpeak with fuel- and lub oil tanks.
On main deck the hull is arranged with: Forepeak, store (3) room and trunking for retractable thruster, RSW-hold/trunk section with central corridors, forward containing vacuum pump room and midship RSW-machinery room. Abaft hold section SB accommodation area, PS/CL control room, engine store/workshop and all aft hydraulic room with steering gear. Accommodation on main deck consists of 3 1 man- and 2 2 man cabins, all with en-suite toilet/shower facilities, laundry and stairs and corridors.
On shelter deck arrangements are: Store (2) room in forepeak, generator room SB and store (3) room, incorporating washing equipment room, room for unloading hoses and hobby room. Enclosed fish loading deck, with centre deck house with water separator and hatches for the 11 RSW-tanks. Abaft midship, full width superstructure with corridor PS. Accommodation in superstructure is arranged with: 4 1 man crew cabins and hospital, all with en-suite toilet/shower facilities, coffee bar, changing room, oil skins room, large wellness area with trim room and steam-bath and stairways and corridors. SB of superstructure to contain trawl workshop/store. Abaft superstructure trawl deck with 1 net drum. PS wet-lab/egg-room and SB enclosed net store. At transom hydraulic stern gate and hydraulic operated guiding pins.
On forecastle deck / boat deck 01, anchor winches in enclosed area. Abaft of this, roll reduction tank and open boat deck 01. Superstructure/deckhouse forward of midship encloses water separator and sampling room. Accommodation inside superstructure/deckhouse comprises Day room/lounge, cinema, mess room, public toilet, galley with provision room (and separate fridge-/freezer rooms) and stairways and corridors. PS fan room for ventilation for engine rooms and hydraulic pump room, as well as exhaust trunks.
Abaft deck house (on boat deck 01), 1 off net drum, arranged for waterfall operation in relation to lower/after drum, aft of net drum 2 off trawl winches. PS tail-end winch and SB topline winch. All aft PS fish pump deck, with fish pump and hydraulic hose reel. Integrated in aft ship construction and boat deck 01 is also trawl gallow, which accommodates 2 main towing blocks as well as tail-end and top line blocks. Net sounder winch is fitted on top of gallow.
On boat deck 02, deck house with ventilation room and accommodation is mounted. Accommodation contains:s6 officers cabins with en-suite toilet/shower facilities, laundry, instrument room, rescue equipment room and stairways and corridors. On PS, aft of deckhouse, MOB deck and –davit.
Wheelhouse on top of deck house, with 360° view. Funnel with deck PS. All as shown on GA.
Design principles for main engine / auxiliary arrangement are as follows:
On reduction gearbox, 1 Power-Take-Off, mounted with a shaft alternator, producing 2800 kWe.
To supply additional electric power, the vessel is fitted with 2 auxiliary engines / gen-sets, producing 940 kWe each. In addition a separate harbour gen-set of 200 kWe is fitted.
During heaving/shooting operations at fishing, when the winch system is in use, the gearbox PTO will be clutched in, and electric power will be supplied from the shaft alternator. When there is demand for full power on the winch(es), there will normally not be same demand for power on the main engine. Following the main engine will be power source for both propulsion and hydraulic system.
During normal towing, the shaft alternator will/can be disengaged (from switchboard), and the electrical power will/can be supplied by either of the gen-sets.
The 2 main gen-sets will be able to connect into main switchboard, controlled by the vessels DEIF Power-Management-System. Further on bus-bar breaker is fitted in main switchboard, allowing aft thruster to be fed off shaft alternator and forward thrusters and vessels hotel load off the diesel generator sets.
Electrical power system is fitted for sliding frequency (60-50 Hz), by means of frequency converters for 400/440 V and for 230 V. This will allow main engine and propeller rpm to be reduced with up to 17%.
Further on, the vessel is fitted with a 2-speed gearbox, giving 2 fixed propeller speed steps, ie 138 and 116 rpm.
Above designs and systems ensures an economical running profile of the vessel.
