US firm oneTANK has developed a small scale, low-cost, IMO Revised G8 Code and United States Coast Guard compliant BWTS.
The system can be installed in larger vessels’ aftpeak tanks, and meanwhile is also suitable for use aboard smaller vessels such as workboats, tugboats, and semi-submersibles. The system is already used on aftpeak tanks on tankers from the Overseas Shipholding Group (OSG) and the Dutch dredger Charlock.
Erma First Managing Director Konstantinos Stampedakis said: “This is a game-changing ballast water treatment technology. It is compact, simple-to-use, and fully automated. It delivers a quick to install additional solution for small ballast tanks on big ships as well as a stand-alone solution for small vessels such as yachts, tugs and offshore support vessels.”
oneTANK treats ballast water within the vessel’s ballast tank and uses an 8.25% or 12.5% sodium hypochlorite (bleach) and 30% sodium thiosulfate solution to treat the ballast water. The system’s footprint is only 600mm x 600mm.
oneTANK Managing Director Kevin Reynolds said: “In Erma First we’ve found the perfect partner to take our innovation to the next level. Over the past 10 years they have been hugely successful in introducing their own large electro-chlorination system to the global merchant fleet; they have a commitment to research & development and crucially they have the financial resources required to market this product internationally.”
