The specialized vessel Far Sapphire for anchorages led the operations at sea
The positioning of the Floatgen mooring system off Le Croisic marks an important step in the progress of this project and paves the way for the installation of the first offshore wind turbine in France.
The elements of the anchoring system were assembled and installed on the SEM-REV test site, 22 kilometers off Le Croisic.
This very innovative system, developed by the start-up Ideol in collaboration with Centrale Nantes, consists in particular of 6 synthetic mooring lines (nylon) – a first for permanent anchoring of this dimension.
The installation of the mooring system has been completed while the concrete floating foundation is under construction by Bouygues Travaux Publics on the port of Saint-Nazaire. Once equipped with the wind turbine, it will be towed before the end of 2017 to SEM-REV, the first multi-technology sea testing site dedicated to renewable marine energies.
“One of the FLOATGEN project challenges was to install an innovative mooring system that needs to meet the production conditions criteria of the floating wind turbine. This demonstrates the value of an experimental site to test innovative technological developments, their implementation and project management when in production. Competent and dedicated teams have highly contributed to the success of the operation”, said Christian Berhault, Head of SEM-REV at Centrale Nantes.
