SMALL BUT MIGHTY.

oneTANK is an innovative, small-scale ballast water treatment system (BWTS) that was developed through Glosten’s internal R&D program. After being approved for funding, it evolved from a concept into a fully built-out system, assembled at Glosten’s Seattle headquarters and distributed to operators around the world.

Based on a patented mixing technology developed by the US Geological Survey, oneTANK automatically treats seawater by applying and mixing the bulk chemicals in-tank, allowing users to treat on their own schedules, avoiding busy in-port times. The system is low cost and complies with the IMO Revised G8 Code and US Coast Guard standards and can be installed in larger vessels’ aftpeak tanks. It is also suitable for use aboard workboats, tugboats, semi-submersibles, fishing vessels, and superyachts. The technology was adopted by Overseas Shipholding Group’s tanker fleet and on the dredger M/V Charlock in the Netherlands.
