Hydro Group

Hydro Group completed cabling support work for the 2MW Floatgen floating offshore wind demonstrator off the French Atlantic coast, working as a sub-contractor under a contract led by Entreprise Travaux Publics de l’Ouest. The work supported the subsea electrical cabling infrastructure at the project site around 19km offshore from Le Croisic, and was carried out alongside French partner Wenex Equipements. Hydro Group supplied subsea electrical connection hardware to enable robust, long-life cable interfacing in Atlantic seawater conditions. Its scope included a 24kV variant of the company’s 36kV Hydro renewable connector, used to connect the device cable to the export cable and to allow three subsea three-phase electrical cables to be mated without compromising the electrical circuit. Hydro Group also delivered a custom-built stainless-steel PDH (power distribution housing) designed to provide flexible in-line connections while maintaining reliability and ease of operation. Hydro Group stated that the PDH’s modular design reduced carbon footprint and incorporated dual water-ingress protection and anti-corrosion properties, targeting reliable sealing and an operational lifespan of around 20 years. The company developed the subsea electrical and optical interconnect package from its factory in Scotland.
