Teknisk beskrivelse (engelsk)
The hull is built in steel with two continuous decks; main deck and shelter deck, and with long forecastle- and boat decks. Wheelhouse, boat decks, funnel and masts are built in aluminium.
Hull shape of round bilge construction with bulbous bow and stern skeg, vertical wave-piercer stem and transom stern.
Below main deck the hull is subdivided into the following watertight compartments: Forepeak, bow thruster-/sonar room, insulated RSW-tank section with 16 tanks and central RSW pump- and manifold room, engine room with main engine connected to reduction gearbox with one, ducted propeller and aftpeak with fuel- and lub oil tanks.
On main deck the hull is arranged with: Forepeak, store (1) room, RSW-hold/trunk section with central corridors, forward containing vacuum tank room and midship RSW-machinery room. Abaft hold section SB accommodation area, PS/CL engine store/workshop, control room and switchboard room. Abaft this, side-to-side trawl stores (2) and all aft hydraulic room with steering gear and SB engine store. Accommodation with laundry, trim room with wellness and stairs and corridors.
In order to create best possible design for low noise, the accommodation is located as far away from the propeller as possible. In addition a number of constructive steps were made, in order to create a low noise level. During trails noise measurements showed levels well below any requirements and recommendations.
On shelter deck arrangement is: Upper forepeak, generator room, workshop/welding cabin and central vacuum compressor room, all SB with stores room (2) PS. Abaft forecastle fish receiving deck, with centre deck house with water separator and hatches for the 16 RSW-tanks. Water separator is built in aluminium with SS loading pipe to each tank.
Abaft midship, full width superstructure. Accommodation in superstructure with: oil skins room, changing room, coffee bar and stairways and corridors. PS of superstructure contains small workshop and entrance to stairs down.
Abaft superstructure trawl deck with 2 net drums side-by-side and a third netdrum PS in waterfall design, all off-set to PS and purse net bin SB, recessed into shelter deck. At transom 2 hydraulic stern gates and hydraulic operated guiding pins.
On boat deck 01, forepeak stores (3) and forecastle stores (4). Abaft of this, roll reduction tanks and pursing deck with 2 purse winches CL/PS. SB forward purse gallow is mounted.
On SB purse fish pump, fish hose- and el-cable reels are mounted. Aft purse gallow and nethauler are mounted midship SB. Also on boat deck 01 level main foredeck crane and SB fish pump crane.
On boat deck 01 abaft midship, deck house in centre. Accommodation in deck house: 5 1-man, 2 2 man cabins, all with en-suite toilet/shower facilities, hospital instrument room and stairways and corridors.
Abaft deck house (on boat deck 01), 2 off trawl winches, all aft fish pump deck, with fish pump and cable reel SB and PS.
Integrated in aft ship construction and boat deck 01 is also trawl gallow, which accommodates 2 main towing blocks as well as tail-end block. 2 off net sounder winches are fitted on top of gallow.
On forecastle deck, 2 anchor winches, with mooring drums in dedicated house are fitted, together with mooring equipment.
On boat deck 02, deck house with ventilation room and accommodation are mounted. Accommodation in deck house: Mess room, day room/TV-lounge, 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. On PS of deckhouse MOB deck and –davit.
On boat deck 03, deck house with accommodation are mounted
Accommodation to contain: 6 1-man cabins, all with en-suite toilet/shower facilities, instrument room and stairways and corridors.
Wheelhouse on top of deck house, with 360° view. Funnel with deck PS.
Design principles for main engine / auxiliary arrangement are as follows:
Vessel is fitted with a 5400 kW main engine, connected to one reduction gearbox, driving one propeller. Shaft alternator of 2700 kW is fitted to gearbox PTO.
To supply additional electric power, the vessel is fitted with 3 auxiliary engines / gen-sets, each producing 1002 kWe as well as a harbour gen-set of 538 kW.
During heaving/shooting operations at fishing, when the winch system is in use, the shaft alternators will be engaged, and electric power will be supplied from here. When there is demand for full power on the winch(es), there will normally not be same demand for power on the propulsion system. Following the main engine will be power source for both propulsion and hydraulic system.
All electrical power systems are controlled by the vessels DEIF Power-Management-System. Further on bus-bar breaker is fitted in main switchboard, allowing aft thrusters to be fed off shaft alternator and forward thruster and vessels hotel load off the diesel generator set.
Electrical power system is fitted for sliding frequency (60-50 Hz), by means of frequency converters for 400/440 V and UPS clean power static supply/converter for 230 V. This will allow main engine and propeller rpm to be reduced with 17%.
