Summary
Most of the scientific activities can only be carried out with the usage of winches. Therefore the winches are among the most important devices onboard. The winch concept aims to redundancy and flexibility. Smooth operation is overseen by the ship's engineers.

Components
Following winches are used onboard:
W1-W4 | 4-drum winches |
W5 | trawl line winch starboard |
W6 | trawl line winch portside (net reel is installed between W5 and W6) |
W8 | auxiliary winch on stern boom |
The winches are hydraulic and are powered by a central hydraulic unit. A side boom is installed on the starboard side for keeping winches and cables on the outboard. The side boom operates one of the 4 wires of the drum winches on the starboard side. Astern the cables are lead outboard via the stern boom.

W3 | 11mm COAX/LWL cable, NSW cross section 138350, length 2000m, 70 kN breaking force, connector GISMA BR40 Gr3 |
W4 | 11mm COAX cable, length 2370m, 19 Ohm/km, connector SubConn IL-2-F (female) requiring IL-2-M (male) connector on the device side |
W5 and W6 | 18mm steel wire, length 2400m on each starboard side and portside |
W8 | 16mm galvanised steel wire, length 40m |
Applying to all single conductor wires: The single conductor wires are lead via a Ramert slip ring transmitter and a RG214U-cable into the Mess- und Registrierraum where the signal can be tapped at normal sockets. Slip ring transmitters are maintained yearly.
