Energy guidance systems for retractable thrusters

Retractable thrusters are used as the primary propulsion systems or for dynamically positioning working ships such as pipe-layers. While they are being extended and retracted from the ship's hull, some have to be fed with hydraulics or water lines and, above all, with motor cables. To guide cables safely, we have energy chains in our range that are ideally suited to the purpose thanks to their robust plastic material and compact construction. They are resistant to salt water, oil, and UV light and are superior to steel energy chains with respect to weight and corrosion resistance.

In addition to individual energy chains and a large number of cables certified for offshore use, we also offer harnessed energy chains. Completely equipped with cables and connectors, they reduce installation and assembly time.
Our engineering team designs guide troughs and system interfaces for cables and hoses accordingly and include them in the CAD model during planning. They do all this in close cooperation with our customers to finally obtain an energy chain system that is reliable and maintenance-free.
