French UV-based treatment company, BIO-UV Group, has secured a contract to retrofit a BIO-SEA ballast water treatment system (BWTS) to a 28,890 tonne cruise ship.

A modular BIO-SEA B01-0085 system with an 85m3/h flow rate will replace the existing first-generation UV-type system during the vessel's scheduled drydocking in Europe this September.

With the cruise ship set to call at San Francisco next year, the new system needs to be compliant with US Coast Guard (USGC) requirements. “Operators of cruise ships fitted with first-generation BWTS technology and which are revising their cruise itineraries to include US ports of call will need to upgrade where possible or replace these systems with USCG-approved units before they can enter US waters," explained Ludovic Rouzel, BWT contracts manager at BIO-UV Group.

Since its market introduction in 2013, BIO-UV Group has supplied 187 BIO-SEA units to an array of ship types, including cruise ships, ferries, mega-yachts, containerships, fishing and offshore support vessels, dredgers, and cable layers.

Xavier Deval, BIO-SEA business director, said, “According to analysts, the number of cruise ships is set to increase from the 314 vessels currently in service to more than 550 vessels by 2027. We anticipate strong growth in the retrofit market as operators begin to replace non-compliant first-generation systems with those that are approved to meet USCG and IMO D8 standards.”

Earlier this year, the French water treatment specialist signed contracts for skid-mounted BIO-SEA 300m3/h capacity units for installation to eight newbuild cruise ships and the company also successfully completed the retrofitting of a modular 450m3/h capacity BIO-SEA unit to a 22,400gt cruise ship.
