en.Wedoany.com Reported - Chantiers de l’Atlantique, together with multiple partners, has launched the RHODÉ project, aiming to develop floating high-voltage direct current (HVDC) electrical connection solutions suitable for deep offshore waters for large-scale offshore wind farms.

The project targets offshore wind farms located in water depths exceeding 100 meters and far from shore, where traditional fixed-foundation substations are limited, making floating solutions a necessary choice. The consortium stated that the project will support the development of 320kV and 525kV floating HVDC systems expected to be deployed from 2040 onwards.

The core objective of the RHODÉ project is to develop and validate key technology modules, while simultaneously fostering the emergence of domestic industrial capabilities in the field of floating electrical connections in France. The project covers design, modeling, laboratory testing, environmental studies, and offshore trials, spanning the entire industrial chain.

Consortium members include Chantiers de l’Atlantique, France Energies Marines, Fondation OPEN-C, GE Vernova, Nexans, RTE (Réseau de Transport d’Électricité), and SuperGrid Institute. The project has received €16 million in funding from the French government's "France 2030" plan.
