Bio-Uv Group has completed the first commercial deployment of its containerised Bio-Sea ballast water treatment system (BWTS) at Port-la-Nouvelle in southern France, supporting the EFGL floating offshore wind project in the Mediterranean. The system treated water deballasted from three floating wind turbine platforms before their offshore deployment.
Under a rental agreement signed with Euroports in May 2025, Euroports provided compliant deballasting services, including water treatment, during the assembly and installation phase. The first platform arrived from Fos-sur-Mer near Marseille in early July, the second in mid-July, and the final unit in August. Over approximately two months, Bio-Uv treated the ballast water of all three platforms in full compliance with IMO D-2 standards and local environmental regulations, before safely discharging it back into the port basin.
The 20-foot containerised Bio-Sea unit offers a modular and mobile solution for treating ballast water during the construction and deployment of floating wind platforms. Positioned quayside, it treats water from platform tanks before discharge, with all treated effluent handled locally to prevent the spread of invasive aquatic species.
The EFGL project comprises three 10MW turbines located 25 km off the coast of Leucate–Le Barcarès near Narbonne, France.
