UK outfit Hydro Group and French partner Wenex Equipements have wrapped up cabling support work on the 2MW Floatgen floating offshore wind project off the coast of France.
Entreprise Travaux Publics de l’Ouest led a contract, assisted by Hydro Group and Wenex Equipements as sub-contractors, to make and install the array cabling infrastructure, 19km from the town of Le Croisic on the French Atlantic coast.
The wind turbine is the first operational unit of a floating foundation concept patented by Ideol, built in concrete by Bouygues Travaux Publics.
Hydro Group chief executive Douglas Whyte said: “Hydro Group identified the need to provide a long-lasting, secure solution suited to Atlantic seawater conditions using tried-and-tested methods to ensure maximum reliability.
“A 24kV variant of our 36kV hydro renewable connector connects the device cable to the export cable, permitting three subsea three-phase electrical cables to be mated without compromising the circuit. In addition, a custom-built stainless steel PDH allowed flexible in-line connections without compromising reliability or ease of operation.”
He added: “The PDH’s modular design reduces carbon footprint and the dual water ingress protection along with the anti-corrosion properties of our technology will provide reliable sealing with a 20-year operational lifespan.”
Wenex Equipement director general Benoit d’Alançon said: “The successful completion of the SEM-REV project is of great importance to our Franco-Scottish collaboration.
“By working together, we have demonstrated the effectiveness of our technical partnership and created a solid foundation for future success.”
From its factory in Scotland, Hydro Group develops the complete subsea electrical and optical interconnect package.
