BIO-UV completes ballast water treatment programme for cruise ship series

BIO-UV Group has completed a five-ship ballast water treatment programme with Chantiers de l’Atlantique, supplying BIO-SEA systems for a series of cruise vessels built at the French shipyard in Saint-Nazaire.
The latest installation was completed on the fifth vessel in the class, delivered at the end of last year and fitted with a BIO-SEA B-Series ballast water treatment system rated for flow rates of 250m³ per hour. BIO-UV Group said the milestone meant every vessel in the series now operated with its ultraviolet ballast water treatment technology.
The company said Chantiers de l’Atlantique selected the BIO-SEA B-Series because of its ability to provide chemical-free ballast water treatment across varying operational flow rates. The system uses ultraviolet light rather than active substances or chemicals to meet IMO D-2 ballast water discharge requirements.
Maxime Dedeurwaerder, sales director, BIO-UV Group, said: “Supplying ballast-water treatment systems to all five vessels is a significant milestone for BIO-UV Group and confirms the strength of our long-term partnership with Chantiers de l’Atlantique and this cruise brand.”
BIO-UV Group said ultraviolet treatment systems reduced operational complexity by avoiding chemical storage, neutralisation and associated safety procedures. The company added that cruise operators increasingly favoured UV-based systems because of tight turnaround schedules, high onboard service demands and stricter environmental requirements at ports on global itineraries.
