- manufacturer: Hatlapa GmbH
- 2 electrical motors with 80 kW, 400 V/50 Hz (3 Ph.)
- electrical re-feeding unit
- automatic spooling system with seperate 10 kW motor
- different cables with a bending radius of 450mm may be used
- 6500 m ROV-deep sea cable (umbilical) in 19 layers (NSW GmbH)
- approx.. 150 kN tractive force with 0-50 m/min in 2nd layer
- breaking force: approx. 30 t
- slip ring (Ramert) with 3 optical fibres
- water cooling of the outer layers
- optinal remote control (cabled control unit)
- winch is permanently mounted on 20' containerbase
- total weight: 30 t incl. cable
One special feature of the winch is the possibility to run the cable lengthwise or orthogonal to the winch's axis.
Deep Sea Cable:
- manufacturer: Norddeutsche Seekabelwerke GmbH
- 19 mm outer diameter; 6500 m length
- 3 steel armoured layers
- weight: 1300 kg/km in air; 1000 kg/km in water
- 240 kN theoretical breaking load
- 400 mm minimal bending radius
- 3 copper wires (4160 VAC) @ 4 mm2
- 3 optical fibres (single mode)
- tested following AODC guidelines
To uncouple the vehicle from ship movements and to keep the cable clear of the ROV, 10-12 floats are attached the outermost 50 – 70 m of the umbilical just above the ROV.
