5.9 m high and 5 meters wide, equipped with pulleys for the cables of the trawl net used for fishing and the heavy sampling equipment launched behind the ship. Capacity 2 x 6 tonnes in the central part, 2 x 8 tonnes on the outermost arms.

The first winch, which is used for fishing, holds 1200 metres of cable with a diameter of 24 mm. The second winch, which is used to send sampling equipment overboard and to set out autonomous measuring stations, holds 4000 meter of cable with diameter of 14 mm. Both winches also have a drum with 350 metres of cable 24 mm in diameter. These winches have a tensile force of 6.4 tonnes at a winding speed of 60 meter per minute. The tensile forces and lengths of cables paid out can be read off constantly at the command post in the pilothouse.

Used to wind in the large-mesh fishing net, capacity 7 m³.

Is located next to the net drum winch and used to pay out a measuring probe along with the fishing net.

This is a swivelling and telescopic crane with a range of between 2 and 11.8 meters and a tensile force of 8 and 2.7 tonnes respectively. Used to take equipment on or off board or move it to the rear deck as well as to launch large pieces of equipment.

This is installed on the lateral work deck and is used to launch equipment to take water and sediment samples. It has a useful height of 1.8 meter and a tensile force of 1 tonne and its outboard working distance is 2.5 meter.

Also located on the lateral work deck and used to place sampling equipment (up to 500 kg) 2.5 meters away from the ship.

both installed on the upper deck. The first, which has a capacity of 1000 meters of stainless steel cable, uses the small hydrologic door. The other has two drums holding 300 meters of steel cable and 1600 meters of stainless steel cable with an electric cable at the core respectively. This winch uses the swinging Davit. The drum holding the 1600-meter cable has touch contacts that establish a connection with the measuring equipment launched while the cable drum turns.

this mast can also be installed to take air samples up to 4.5 meters in front of the bow of the Belgica.
