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

The equipment on pipelayers must be able to withstand harsh weather conditions on the high seas and fulfil high safety requirements. A large number of heavy cables supply the tower, tensioner, welding systems, heavy-duty cranes and extendable ship drives with energy, data and power. Our cable carrier systems have been used successfully for years to protect and safely guide the cable packages. e-chain® of the E4.1 series are corrosion-free, vibration-resistant and comparatively lightweight. Their space-saving design is a great advantage for use on workboats where installation space is limited.
The same applies to our rotary modules, which are used in slewing cranes as an alternative to slip rings. By using cable-friendly energy chains in the complete system, maintenance costs can be reduced by 90 % compared to slip rings.

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.
