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.
Both, stern boom and side boom has SDL of 3t.
The crane has SWL of 2.5t in full expansion and SWL of 5t in limited expansion until 7m.

W2 | 30 kN | 0..80m/min | no |
| W3 | 30 kN | 0..80m/min | yes |
| W4 | 20 kN | 0..120m/min | yes |
Trawl line winches
| capacity intermediate rope layer | max. rope speed intermediate rope layer | slip ring transmitter | |
|---|---|---|---|
| W5 and W6 | 40 kN | 0..60m/min | no |
Auxiliary winch on stern boom
| capacity intermediate rope layer | max. rope speed intermediate rope layer | slip ring transmitter | |
|---|---|---|---|
| W8 | 30 kN | 0..40m/min | no |
Wiring
State of November 2024
W1 | 8mm COAX cable, length 2380m, 9.2 Ohm/km, connector SubConn IL-2-F (female) requiring IL-2-M (male) connector on the device side |
W2 | 12mm wire, steel wire SOLIFLEX 32, length 1630m, 108,7 kN breaking force |
W3 | 11mm COAX/LWL cable, NSW cross section 138350, length 1950m, 70 kN breaking force, connector GISMA BR40 Gr3 |
W4 | 11mm COAX cable, length 2170m, 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 1800m on each starboard side and portside |
W8 | 16mm galvanised steel wire, length 40m |
Winches W1, W3 and W4 have slip ring collector and W3 additionally fiber optic transmitter for electric supply and data communication. From each winch a cable of type RGU214U leads to the patch field in Mess- und Registrierraum. Connectors of patch field are N-Type sockets with outer thread. An adapter to BNC socket is available. The fiber optic patch field has two plugs of ST type (bayonet socket).
The pins of fiber optic socket GISMA BR40, Gr 3 (GISMA 40.06.3.06.2.00) are:
Pin 1+2 combined for electric power, center Coax
Pin 4+5 combined for electric power, screen Coax
Pin 3 for fiber optic (line 1)
Pin 6 for fiber optic (line 2)
Cables and wires from 4-drum winch can be traced via pulleys to stern boom.
