BWTS THAT TREATS BALLAST INSIDE THE TANKS RECEIVES USCG APPROVAL

Tuesday, February 5, 2019 

US company Envirocleanse, part of Charter Brokerage, has received US Coast Guard Type Approval for its inTank Ballast Water Treatment System (BWTS).

inTank is claimed to be the only Type Approved BWTS which treats water during the voyage, leaving port activities unchanged.  The inTank BWTS uses a dispersion system patented by the US Geological Survey and developed by marine engineering firm Glosten for mixing the active substance in the ballast tanks.

Envirocleanse describes the inTank BWTS as "second generation thinking which differentiates itself from the rest of the industry by completely by-passing the operational and commercial risks associated with ballast treatment during cargo operations". inTank treats and neutralises in the tank. This means technical compliance with the TA Certificate is achieved before discharge. inTank also allows the vessel to actively control any regrowth potential for as long as ballast remains in the tanks. These abilities mean inTank provides the most certainty of compliance with the least impact to operations.

"Adding the US Coast Guard type approval to the IMO Final Approval, with no temperature or salinity restrictions, meets the needs of ships traveling in world-wide trade," said Kevin Reynolds, Principal, Glosten.

Matt Hughes, Sr VP of Envirocleanse said: "All applicants to the USCG for type approval are conventional in-line systems.  All but one applicant uses a filter. Considering port operations are the most sensitive time for vessel activities with cargo and ballast operations often being interdependent, inTank offers a more developed, elegant solution to ballast water compliance. Moving ballast treatment activities from the port to the voyage removes risk from port activities. The critical benefits of inTank include no filters, no power consumption in port, normal ballasting operations, and no restriction due to ballast water quality such as salinity, UVT, turbidity or temperature. These are all part of the reason the Envirocleanse inTank BWTS will be a better solution for many vessels."
