Aude: a 24-kilometer XXL cable delivered for experimental floating wind turbines

The floating wind turbines off the coast of Port-La Nouvelle and Gruissan will be gigantic. And their electricity production capacity itou. For such machines, a corresponding connection cable was required. Very recently, RTE delivered it to Eolmed.

At the start of the year, the floating electrical hub buoy was installed off the coast of Gruissan and Port-La Nouvelle, where the three experimental wind turbines from Eolmed, a subsidiary of Qair, will be located. A mega power strip 16 meters in diameter now anchored at a depth of 60 meters. This will be intended to recover and transform the electricity supplied by Eolmed’s three mega wind turbines.

RTE has signed the delivery of the cable which will transport the current produced by the three Eolmed wind turbines.

This electricity will be sent back to shore, inevitably, via a cable of impressive dimensions which, after months of a titanic project, has just been delivered by RTE (electric transmission network) to the operator. To carry the current produced by the steel monsters and its wind turbines, a cable was needed in proportion. The floating wind turbines will be carried by floats of 3,200 tonnes each, the size of the Arc de Triomphe. As for the wind turbines, they will peak at 140 with a blade span of 160 meters.

This impressively large cable was delivered in a single piece of 24 kilometers and was buried (buried in the sand) at a depth of two meters to allow fishing activities. Landing (land connection to the electrical substation) required drilling to a record depth of 860 meters. This innovative technology, through which data will also be transmitted by fiber, cost Eolmed €45 million and will make it possible to transport a whopping 63,000 volts.

Jean-Marc Bouchet, CEO of Qair, and Laurent Vergnet, offshore director for France, therefore signed the “delivery note” a few days ago with Christelle Limousin, project director at RTE and Renaud Rossetti, operational manager. A titanic project which mobilized several companies in France, Italy and Germany and very substantial nautical resources.
