Built in the port of Saint-Nazaire, Floatgen, France’s first floating wind turbine, has taken a new major step forward. The concrete foundation was floated on 23 August after a construction process which began in the autumn of 2016.
After installing the wind turbine’s mooring system off the coast of Le Croisic last July, the foundation took to the water, marking a new key stage in the project implemented by Ideol, the Ecole Centrale de Nantes and Bouygues Travaux Publics. The concrete foundation was tugged into the Forme Joubert Lock, a dry dock at the entrance to the port of Saint-Nazaire to be floated, a tricky technical operation to float off the floater from the three barges on which it had been built.
“Everything was placed in dry dock on concrete and wooden blocks which support the keel of a ship during dry construction. The barges were then filled with water to be sunk. When the lock was filled with water, the floater disengaged from its support”, explains Perceval Modiano, project manager at Bouygues Travaux Publics.
The imposing, 5,000-tonne concrete structure, 36 metres square by 9.5 metres high, will soon be accommodating a 2-MW wind turbine. The project’s next stage will be to mount the wind turbine’s tower, the turbine and its blades. The final unit will top out at over 80 metres.
By mid-October, it will be towed to the SEM-REV installation site, 22 km off the coast of Le Croisic for initial trials covering a period of 2 years.
Highlight of the worksite: “we have developed a lightweight, self-compacting type of concrete to minimise the weight of the structure and pour the concrete without vibrating it,” explains Régis Bigard, head of the Floatgen project with Bouygues Travaux Publics.
