Coating Systems for France’s EOLMED Floating Offshore Wind Project

The 30 MW offshore wind pilot project required coatings for exterior steel, splash-zone exposure, interior ballast-tank-like areas and transition pieces.

Jotun supplied coating systems for the EOLMED floating offshore wind project, located approximately 18 km off the coast of Gruissan in southern France.

The 30 MW pilot farm is owned by Eolmed. Its floaters were designed by BW Ideol and manufactured and assembled by MP Archimed. The project includes three Vestas V164-10 MW turbines installed on floating steel foundations.

EOLMED is designed to generate nearly 110 million kWh annually and was completed in September 2025 at Port-La Nouvelle in Occitanie. The project is expected to operate for 20 years.

“This is an exciting project to be a part of. The floaters are massive steel structures measuring approximately 45 m × 45 m × 17 m, including the demanding splash zone, which sets high demands to the coating on the external part,” said Xavier Pianezzi, sales manager for energy and infrastructure at Jotun.

The coating scope included the exterior surfaces of the floaters, including the splash zone, as well as interior areas comparable to ballast tanks. The interior areas represented a larger coating surface area than the exterior portions of the floaters.

“As EOLMED represents a major step forward for floating offshore wind in France, we are reliant on good partnerships through all steps in the project. The collaboration with Jotun has been instrumental in meeting our technical and sustainability goals, ensuring the long-term success of this pioneering project,” said Thomas Beucler, floating foundation package manager for EOLMED.

Jotun’s solvent-free coating systems were used in the interior areas in line with the owner’s sustainability requirements. Application work was completed in partnership with steel fabricator Matière and Italian applicator Petrol Lavori.

In addition, Jotun supplied coatings for external equipment and transition pieces at the Navacel yard. The work used a Jotun NORSOK 1 system to meet project technical specifications. Across the project, Jotun provided technical support during coating application and execution.

“The scope that included both exterior and interior coatings for all three floaters consumed nearly 60,000 L of Jotacote Universal S120, along with Penguard Pro GF and Hardtop AX. We are very proud to have secured this significant project, and I am sure it may serve as a strong reference for Jotacote Universal S120 and our overall capabilities, both within and outside of the European market. To enable the future of energy, assets need long-lasting protection even in the harshest environments,” said Torgeir Bringeland, marketing manager for Jotun Europe Sales.
