Nybygning D97 Antarctic leveret fra Karstensens Skibsværft

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, funnel and masts are built in aluminium.

Hull shape 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, bow thruster-/sonar room, insulated RSW-tank section with central RSW pump- and manifold room, engine room with main engine connected to reduction gearbox with ducted propeller and aftpeak with fuel- and lub oil tanks.

On main deck the hull is arranged with: Forepeak, electronics room, room for unloading (vacuum) system, trunks for RSW-tanks with centre corridor with RSW-units, accommodation section SB with workshop, exhaust and ventilation trunking and engine control room/switchboard room. All aft/PS hydraulic room with steering gear.

Accommodation on main deck is arranged with 7 1-man and 2 1-officer crew cabins all with en-suite toilet/shower compartments, trim room and corridor and staircase.

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: Store (1) forepeak, generator room and aft/under forecastle store (2). Abaft forecastle fish receiving deck, with centre deck house with water separator and hatches for the 8 RSW-tanks. In way of hatches, fore deck crane is mounted.

Abaft midship, full width superstructure. Superstructure is arranged with: Deck store, changing room with oil skin drying area, day- and mess room, galley with provision stores and corridor with staircases.

Abaft superstructure trawl deck with 2 net drums. On transome, 2 hydraulic operated stern gates with roller on top are recessed. In front of each stern gate, 3 hydraulic operated guiding poles are fitted. Above-deck tracks for midwater weights are also fitted.

After part of trawl deck PS is arranged as trawl pumping deck, with fish pump, hose reels and tail-end block.

On forecastle deck, anchor winch in dedicated house, together with mooring equipment. Abaft of this, roll reduction tank and forecastle deck.
On boat deck, abaft midship, deck house in centre. Accommodation in deck house with skipper- and mates cabins and instrument room. Room for accommodation ventilation is also incorporated into the deck house. PS funnel with exhaust and ventilation intakes.

All aft boat deck in full width with SB and PS walkways forward. Integrated in aft ship construction and boat deck is also trawl gallow, which accommodates 2 main towing blocks as well as tail- and top line blocks. Net sounding winch is fitted on top of gallow.
Wheelhouse on top of deck house, with 360° view. Funnel with deck for MOB-boat and –crane PS.

Design principles for main engine / auxiliary arrangement are as follows:
On reduction gearbox, 1 Power-Take-Off, mounted with a shaft alternator, producing 1650 kWe.
To supply additional electric power, the vessel is fitted with 2 auxiliary engines / gen-sets, producing 930 respectively 550 kWe. In addition a harbour set of 122 kW 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, and the electrical power will/can be supplied by either of the gen-sets.
The 2 gen-sets will be able to connect into main switchboard, controlled by the vessels DEIF Power-Management-System.

Electrical power system is fitted for sliding frequency (60-50 Hz), by means of frequency converters for 400/440 V and clean power static supply/converter for 230 V. This will allow main engine and propeller rpm to be reduced with 17%.

Above designs and systems ensures an economical and safe running profile of the vessel.
