The renovation of the Turballe port is a sign of the rapid expansion of renewable sea energies in France. In fact, the port's extension will mean the town can now accommodate EDF-Renewables' maintenance base for the first offshore wind farm in France, located off the Saint-Nazaire coast.

With an investment of 53 million euros, this large-scale project will take place in 2 successive stages for the port's gradual development. Charier was selected to complete the 1st stage of the project.

Besides the development of renewable sea energy, the joint association of Loire-Atlantique ports chose to rethink its multiple-activity sea area thereby enabling fishing, boating, ship repair and passenger transport activities to continue expanding and experience further rapid growth.

To support this metamorphosis, our teams are on deck, covering all lines of work. While the quarries produce the necessary aggregates, the Routes de La Turballe agency takes care of receiving and storing the Xblocs (4,000 in total), the excavation team gains ground at sea to build the new sea wall, while the civil engineering and maritime works teams prepare underwater the new fairway and the integration of the structural works.
