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.

Wiring

State of October 2019

W1

8mm COAX cable, length 2935m, 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 2000m, 98 kN breaking force

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


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.
