DESCRIPTION:
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 engine workshop and engine store, PS/CL engine control room with engineers changing room and switchboard room. Abaft this, central trawl-/net storage tanks and PS trawl stores. All aft hydraulic room with steering gear.
On shelter deck arrangement is: Upper forepeak, generator room and room for water maker (RO-plant), roll damping tanks at full width. Abaft these fully enclosed loading deck with centre deck house with RSW-control room. Loading deck to incorporate 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.
Abaft superstructure large trawl deck with 2 net drums side-by-side slightly 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 sides of trawl deck, hydraulic workshop PS and trawl deck store / workshop PS.
On boat deck 01, forepeak stores (3) and forecastle stores (4). Abaft of this pursing deck with 2 purse winches CL/PS. On boat deck 01, deckhouse fully encloses water separator.
On boat deck 01 abaft midship, deck house in PS. Accommodation in deck house: 5 1-2 man cabins, all with en-suite toilet/shower facilities, laundry and stairways 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.
Abaft deck house (on boat deck 01), 2 off trawl winches, all aft fish pump deck, with double fish pumping stations SB as well as 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 / boat deck 02, 2 anchor winches, with mooring drums in dedicated house are fitted, together with mooring equipment.
On boat deck 02, deck house with and accommodation are mounted. Accommodation in deck house: Mess room, day room/TV-lounge, cinema, galley with provision room (and separate fridge-/freezer rooms), 4 off 1-man cabins all with en-suite toilet/shower facilities, hospital and stairways and corridors. PS fan room for ventilation for engine rooms, as well as exhaust trunks.
On SB purse fish pump, fish hose- and el-cable reels are mounted. Also on boat deck 01 level main foredeck crane and SB fish pump crane.
On PS of deckhouse MOB deck and –davit.
On boat deck 03, deck house with accommodation are mounted
Accommodation comprises: 6 1-man cabins, all with en-suite toilet/shower facilities, instrument room, trim room with wellness section, including steam bath and stairways and corridors.
Wheelhouse on top of deck house, with 360° view. Funnel with deck PS.
All as shown on general arrangement.
Design principles for main engine / auxiliary arrangement are as follows:
Vessel is fitted with a 7320 kW main engine, connected to one reduction gearbox, driving one propeller. Shaft alternator of 3300 kW is fitted to gearbox PTO.
To supply additional electric power, the vessel is fitted with 2 auxiliary engines / gen-sets, producing 1348 respectively 940 kWe as well as a harbour gen-set of 200 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%.
