Strong energy supply systems for cable- and pipe-laying equipment

The equipment on pipe-layers must withstand harsh weather conditions at sea and meet stringent safety requirements. A large number of heavy cables supply the tower, tensioner, welding systems, heavy-duty cranes, and retractable ship propulsion systems with energy, data, and power. For years, our energy supply systems have been used successfully to protect and safely route cable packages. E4.1 series e-chains are corrosion-free, vibration-resistant, and comparatively lightweight. Designed to save space, they are a great advantage on working ships, where installation space is limited.
The same applies to our rotation modules, which are used in rotary cranes as an alternative to slip rings. Maintenance costs with cable-friendly energy chains in the complete system can be 90% less than with slip rings.
 
Pipe-layers

Pipe-laying tower

At the foot of the pipe-laying tower, the entire cable package, along with hydraulics or water, must be reliably routed vertically. The large E4.350 e-chain is used here.

Tensioner

Compact with low dead weight: E4.1 series e-chains with various external dimensions are used to supply energy at the channels for prestressing cables and pipes.

Rotary cranes

Rotation modules with internal e-chains ensure reliable guidance of hydraulics, data, and signals in knuckle boom and rotary cranes – lightweight, compact, and delivered ready for connection.
