Energy supply systems and cables for
offshore construction

Conditions at sea, like those on land, are rough and extremely demanding for system components in the oil and gas industry. Dirt, salt water, vibration, extreme temperatures, high levels of mechanical stress, and the explosive environments are just some of the difficult conditions to which cables, hoses, and energy supply systems are exposed in oil and gas extraction. We have products suitable for these specific application areas. In land and offshore drilling rigs, they ensure a reliable energy supply on such systems as the cantilever and in highly dynamic pipe handling. Light and maintenance-free. Thanks to our engineering team and DNV- and NEK-certified chainflex cables, we also offer ready-to-connect complete systems that are tailored to your requirements.

Modular e-loop® service loop alternative for
offshore industries

The alternative to the service loop to guide cables safely in hanging applications. Ideal for three-dimensional and offshore construction.

Combines the advantages of a plastic energy chain with those of a high-strength pull rope.
Inside the chain, the pull rope transfers the tensile forces to the mounting brackets and the structure. As a result, the cables are kept completely free of strain.
Convenient: individual cables can be replaced.

Offshore construction success stories

RBR in a Liebherr heavy-duty rotary crane

Energy chain wrapped around the crane leg

Heavy-duty Liebherr rotary cranes are used on installation vessels for offshore wind turbines. They can lift components weighing up to 1,500 tons. Energy transfer through the slewing ring is ensured by an innovative energy chain concept that allows the boom to rotate up to 900 degrees.
