Innovative offshore cable solutions

The project is a CETP (Clean Energy Transition) project, the Swedish part is funded by the Swedish Energy Agency. Participating in the project, in addition to RISE’s Corrosion and Smart Hardware departments, are eleven organizations/companies from Europe.

The project further develops dynamic cables for offshore energy. Inside the cables, fiber optic sensors are used to detect how the cable moves in the harsh environment out at sea. With the help of modelling, the movement and its impact on the cable’s service life can be predicted.

The project is developing a method that makes it possible to paint the cables out at sea, at a speed of 20 m/min. The cable is painted with an environmentally friendly paint system that is robust and does not contain toxins, but still prevents fouling. The project will also develop a robot with the appearance of a bracelet, in order to be able to remove the fouling that still remains.

The cables used in the project are recycled using a new developed method.

The developed methods and products will be tested on a smaller scale in labs and nearshore testing outside Kristineberg in Sweden and in the Mediterranean Sea, and finally launched in an ocean demonstration in the Mediterranean.
