BIO-UV to retrofit BWTS replacement

French ultraviolet water treatment company BIO-UV Group is to replace a first-generation ballast water treatment system installed on a 28,890gt cruise vessel. The replacement is necessary because operators of the unnamed ship plan 2020 vessel itineraries that will involve US ports, including San Francisco. The ship’s existing treatment system does not comply with US Coast Guard regulations and a modular BIO-SEA system will now be installed, with a flow rate of 85m3/hour.
Ludovic Rouzel, the company’s BWT Contracts manager, noted that this is the first project with this cruise line but that a similar project has already been completed and others are under discussion. A retrofit involving a treatment system with a capacity of 450m3/hour was carried out by the company in March on board a 22,400gt cruise vessel.
Rouzel commented: “Operators of cruise ships fitted with first-generation BWTS technology and which are revising their cruise itineraries to include US ports will need to upgrade (when possible) or replace these systems with USCG-approved units before they can enter US waters. We are discussing similar retrofit projects with a number of cruise lines.”
Earlier this year, BIO-UV signed a deal for the installation of 300m3/hour skid-mounted systems on board eight new cruise ships. The rapidly expanding cruise sector, including the niche expedition cruise segment, offers significant potential for the company’s smaller capacity units ranging from 10-90m3/hour.
Since it entered the ballast water treatment market in 2013, BIO-UV Group has supplied 187 BIO-SEA units to the operators of various vessel types including cruise ships, ferries, mega-yachts, container ships, fishing vessels, offshore support vessels, dredgers and cable-layers.
