Fore and aft decks

For operating a towed body, the fore deck holds a boom (crane) with 50 m wire cable, 15 mm diameter and 12 conductors.

The hydrography deck is located midships, on the port side. Winches and hydraulic beams are available for hydrographic investigations:

• 1 CTD winch; 1,800 m wire cable, 8.2 mm diameter, 7 conductors
• 1 hose winch; 150 m hose with integrated power conductors
• 1 oceanographic winch; 2,000 m wire, 400 kg
• 3 hydraulic booms, extending up to 5 m from the hull

The aft deck is designed with a slipway for launching
equipment.
Ample deck space allows for various tasks to be carried out.
The aft deck is equipped with trawl drums, booms and winches used for fishing with trawling and special equipment. In addition, the aft deck holds:

• 1 winch for small gear; 1,200 m wire cable, 8.2 mm diameter, 7 conductors
• 1 winch; 8oo m wire, 16 mm diameter
• 4 auxiliary winches
• 2 telescopic handling cranes; max load 3,000 kg up to 12 m extension from the hull

Accommodations

DANA houses a total 38 scientists and crew in fully airconditioned single cabins, all with own toilet and bath.
A cabin with separate bedroom and bath is available for the scientific leader of the survey. Combined messes and dayrooms have radio, TV and VCR. In addition, a conference room with AV equipment is available.

DANA has its own laundering facilities, library, store, sauna and gym.
       
Engines

The two B&W Alpha diesel engines with Lohmann & Stolterfeht reduction gear develop 800 hp at 800rpm.

With both engines, DANA's maximum speed is 15.5 kn. Normal cruising speed (using one engine) is 12.5 kn. At this speed, DANA's fuel capacity allows for 50 days of operation.

Three Cummings auxiliary engines develop 737 kW each at 1,500 rpm. A stabilization system supplies stable power (220/380 V, 50 Hz). IT equipment is further secured against power failure through UPS.

Aft and fore thrusters. Driven by 2*425 hp, hydraulic motors.

Communication

DANA is equipped with a modern GMDSS station (Global Maritime Distress and Safety System).

The radio station has Inmarsat A and C satellite equipment for global telex, fax, data and telecommunication.

In addition, HF, MF, and VHF equipment and NMT mobile telephone and fax are available.

A fast radio data link for transferring data to the land-based data network is available at Hirtshals harbour.

Navigation

DANA may be navigated from three command stations: the main navigation bridge, the stern bridge, and the crow's nest. High maneuverability is acheived by the Poscon maneuvering system which controls the variable pitch propeller and the side thrusters.

All navigation equipment is state of the art and is constantly updated. For both security and scientific reasons, all vital systems are duplicated. The navigations equipment currently includes three radar systems, D-GPS, Transit Satellite, Decca,. Loran C, Doppler log, several echo sounders and direction finders as well as PC-based sea maps (NaviSailor).
