Unlike bottom-fixed offshore wind turbines, floating turbines are characterized by the use of energy transport cable elements deployed between the seabed and surface, at the level of the floater. These elements called dynamic cables are several hundred meters in length and are subjected to motion from the floating support platform, waves and marine currents. They are also very sensitive to bio-fouling. These dynamic cables are also important for other floating ORE technologies: ocean thermal energy conversion, wave, tidal or hybrid platform.
To identify the main orientations for the realisation of a test bench dedicated to the tests in real conditions of an in-service monitoring method of medium and high voltage dynamic cables.
