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.

Wiring
State of June 2015
W1 | 8mm-single conductor wire, length 2070m, 9.2 Ohm/km, connector SubConn IL-2-F (female) requiring IL-2-M (male) connector on the device side |
W2 | 6mm-wire, length 2750m, steel wire Niro, 20kN breaking force |
W3 | 11mm-single conductor wire, length 890m, 19 Ohm/km, connector SubConn IL-2-F (female) requiring IL-2-M (male) connector on the device side |
W4 | 11mm-single conductor wire, length 1760m, 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.
