Overview production of heavy special cables

Components already commissioned and advantages of the systems

Overall view of the turntable: accumulator, loading system and the control room

Münstermann offers plants and components for the production of special cables as for example those needed for offshore wind farms. A typical application is the transfer of the cable from the stranding machine to the turntable, which acts as a buffer store for the cable. Münstermann can also supply transport systems, which unload the cable from the storage turntables and lay it onto an appropriate turntable on the cable-laying ship. The assembly of this unit is both possible outdoors and indoors as well as near the sea.

Components already commissioned

• Turntables in the most varying dimensions and different weights (e.g. diameter up to 35 metres and a load capacity of up to 4,000 tonnes)
• Transportation and handling systems, for instance, from the stranding machine to the turntable
  • Cable pull systems (tensioners) for an efficient and safe transportation of the cable produced
  • Safety measures during a break in the production process using a so-called accumulator
  • A loading arm for the transfer of the cable to the turntable
• Complete control systems of the plants

Buffer store during pro­duction of the cable (accumulator)

Advantages of the solutions developed

• Tensioners are designed for cables up to approximately 300 millimetres in diameter and for a reeling speed of up to 20 metres per minute.
• Turntable drive is reversible.
• The unit operates very quietly when using a wheel block compensator.
• Tolerances in height are compensated for by a wheel block compensator.
• Construction tolerances are compensated for by a special tangential drive.
• Assembly both outdoors and indoors is possible.
