Octopus, or “Offshore electrical ConnecTiOns’ hub: Paving the way towards Underwater Solutions” to give it its full name, is one of five innovative projects to be selected for further development following the Sea-GRID Call for Expression of Interest launched by Centrale Nantes, Enedis and RTE.

SuperGrid Institute, in partnership with Naval Energies (FR) and Nexans (BE) developed the Octopus project which aims to demonstrate a new technology that can reduce the cost of electricity produced via renewable marine energy. The innovative power hub proposed will limit the impact of a failure on a dynamic cable in a floating offshore wind farm structure by making it possible to isolate the faulty line while maintaining power flow from the non-affected wind turbines.
