Geodis has completed a major operation in partnership with Eiffage Metal for the transport and float-off of three floating substructures of 2,500 tons.

The turbine foundations, designed by Principle Power, are part of the "Les Éoliennes Flottantes du Golfe du Lion" (EFGL) pilot project, one of the largest floating offshore wind farms in the world.

Geodis noted that this large-scale operation was managed by a dedicated team, onsite between the end of April and early June 2025.

The complex move took place within the Grand Port Maritime de Marseille (GPMM), from the Eiffage Darsette site to the Carfos terminal in Fos-sur-Mer (France).

The project required an extensive engineering phase, including the design of grillage and sea fastening systems, precise ballasting calculations, and close coordination with local port authorities. High environmental and safety standards were also applied throughout the process.

To execute the float-offs, Geodis said it mobilized a semi-submersible barge, specifically selected for its suitability. The process involved a carefully sequenced ballasting operation to ground the barge and allow the floaters to be safely launched into the water.

Despite strict weather requirements, the float-offs were conducted efficiently and without incident.

"The EFGL project, with 30 MW of capacity, represents nearly 10% of the operational floating wind turbines currently installed worldwide, so we are very proud to have contributed to its success. Also, GEODIS’ seamless execution of two consecutive float-offs within six days highlights the potential scalability and industrial feasibility of commercial size floating wind energy projects," said Nicolas Bonnier, global manager offshore wind solution, project logistics at GEODIS.

The success of the project, Geodis' first in floating offshore wind, marks a key milestone and reinforces the Group's strategic commitment to strengthening its position in this emerging sector.

Building on this experience, Geodis said it will continue to develop innovative, tailor-made solutions specifically designed to meet the unique requirements of future commercial-scale projects.
