Port-Side Ballast Water Treatment & PortoBallast
Sea Clean AS helps port teams and vessel stakeholders define port-side treatment and complete PACT Marine onboard BWMS project scopes.
Sea Clean's first container has arrived
Sea Clean reports receipt of its first Euro Tech PortoBallast container on 7 October 2026. The supplied unloading photograph shows a side-loader truck at the waterfront. We intend to use the container as a training facility and a practical reference for vessel and port-side treatment discussions.
Euro Tech Holdings identifies itself as Nasdaq: CLWT in its June 2026 announcements and publicly named Sea Clean as its Norwegian strategic partner. PortoBallast is the product name, not a listed issuer. No unverified Mini/Micro variants are asserted.
The August 2026 brochure describes containerised filtration and medium-pressure UV treatment, with a separate function for neutralising surplus oxidants. Its reference treatment range is 50–300 m³/h. These manufacturer figures are subject to change and require confirmation against the offered unit, water envelope and project interfaces.
Arrival is not a commissioning record or discharge permission. Training dates, rental or operated-service availability, suitability, utilities, testing and required approvals need individual confirmation. Email links open drafts only; nothing is submitted to a website inbox.
