BIO-UV Group has completed the first commercial deployment of its containerised BIO-SEA ballast water treatment system at Port-la-Nouvelle in southern France, supporting installation of the EFGL floating offshore wind project in the Mediterranean.
The project, operated by Eoliennes Flottantes du Golfe du Lion (EFGL) – a joint venture between Ocean Winds and Banque des Territoires – marks the first floating offshore wind development in the Occitanie region and a milestone for integrating environmental technologies into renewable energy operations.
BIO-UV’s containerised system was used to treat deballasted water from three floating turbine platforms before offshore deployment. The rental agreement, signed with Euroports in May 2025, enabled compliant water treatment during the assembly and installation phase. Over two months, BIO-UV processed ballast water from all three platforms in line with IMO D-2 standards and local environmental regulations.
BIO-UV Group solutions business unit director Maxime Dedeurwaerder said: “This project is an important milestone for BIO-UV Group. It is the first time our containerised ballast water treatment technology has been deployed commercially in support of the offshore renewable energy sector, demonstrating not only the performance and reliability of our UV-based solution but also its versatility in new marine applications beyond conventional shipboard use.”
Ocean Winds France business development director Dominique Moniot said: “Protecting marine biodiversity is critical to the sustainable growth of offshore wind. By ensuring ballast water is treated before it is released, we help prevent the transfer of non-indigenous species, supporting the ecological integrity of coastal waters as new renewable infrastructure is installed.”
Euroports eolic director Remy Moron said: “BIO-UV’s system allowed us to offer a complete and compliant ballast water treatment service to our client Ocean Winds for the EFGL project without transporting this water by truck to permanent facilities, and without impacting the assembly planning.”
BIO-UV Group chief executive Laurent Emmanuel Migeon said: “Offshore wind is entering a new phase where environmental protection, regulatory compliance and operational efficiency must go hand in hand. This project proves that portable ballast water treatment can play a vital role in achieving those objectives, and we look forward to building on this success as the floating wind market scales up.”
The 20-foot containerised BIO-SEA unit, developed during the EU-funded ELBE programme, provides a modular, quayside solution for treating ballast water from floating platforms before discharge. The EFGL project comprises three 10MW turbines located off Leucate-Le Barcarès near Narbonne and represents a key step in the growth of floating wind in the Mediterranean.
