oneTank BWTS Gains US Coast Guard Type Approval

oneTank, LLC has been granted a U.S. Coast Guard Certificate of Approval (162.060/35/0), completing the suite of international approvals required for its ballast water treatment system.

The oneTank ballast system is a simple, low-cost treatment option intended for vessels that do not need a complex solution. The system was developed to simplify the installation and treatment of the tanker aftpeak tank, an ideal “one or a few tanks” application. With an arrangement footprint of just two square-feet, it is a great fit for workboats where space and power are severely limited.

This award follows the DNV GL Certificate of Approval awarded on behalf of the Norwegian Maritime Authority in compliance with the International Maritime Organization BWMS Code in July of 2020.  

“We are pleased to receive these approvals, applicable for all ballast water salinities and temperatures. Superintendents and operators have been looking for a product like oneTank, keeping it simple when you only need to treat one or a few ballast water tanks,” stated Kevin Reynolds, Managing Director of oneTank, LLC.

Sean Ritchie, oneTank’s Chief Engineer, said, “This is a third-generation technology. What differentiates oneTank from other treatment systems is its simplicity, which makes it easy to install, operate and service.”

oneTank is a derivative of the inTank dispersal system brought to market by parent company Glosten, Envirocleanse, and Scienco/FAST and patent protected by U.S. Geological Survey. The inTank system treats ballast water within the vessel’s ballast tank and has no filters, no ultra-violet bulbs, and no electrolytic generators. Similarly, oneTank is an in-tank, bulk chemical treatment process for ballast tanks up to 4,000 cubic meters.
