Subsea cable and connector specialist, Hydro Group, alongside its French regional partner Wenex Equipements, has completed its scope of work on the SEM-REV marine renewable energy project.
In 2015, the Franco-Scottish consortium won a £2.5 million contract to manufacture and install the array cabling infrastructure, 12 miles from the town of Le Croisic on the French Atlantic coast.
The Floatgen turbine is now fully operational. Its connection to the grid will enable the supply of electricity to 5,000 inhabitants.
Douglas Whyte, CEO of Hydro Group, 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 (HRC) 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.
“Our PDH’s modular design greatly 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.”
The turbine is the first operational unit of the floating foundation concept patented by Ideol, built in concrete by Bouygues Travaux Publics.
Benoit d’Alançon, director general of Wenex Equipements 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.”
