First containerised ballast water treatment for EFGL floating wind project

Bio-UV Group has completed what it says is the first commercial deployment of a containerised ballast water treatment system in support of a floating offshore wind installation, treating ballast water from three turbine platforms at Port-la-Nouvelle in southern France. The units were assembled for the EFGL floating wind pilot project in the French Mediterranean, operated by Eoliennes Flottantes du Golfe du Lion, a joint venture between Ocean Winds and Banque des Territoires.
Under a rental agreement with Euroports, the 20-foot BIO-SEA container was positioned quayside during the assembly phase, allowing water to be deballasted and treated before discharge, in compliance with IMO D-2 standards and local regulations. The three platforms arrived sequentially over July and August 2025. Each consists of a triangular structure of three floaters and supports a 10MW turbine bound for a site 25km offshore near Leucate-Le Barcarès. Bio-UV said the deployment avoided the need to transport ballast water to permanent treatment facilities and prevented the transfer of invasive species during installation.
“This project is an important milestone for Bio-UV Group,” said Maxime Dedeurwaerder, solutions business unit director. “It is the first time our containerised ballast water treatment technology has been deployed commercially in support of the offshore renewable energy sector.”
The company expects wider uptake in future floating wind developments.
