Why HullWiper

HullWiper collects marine fouling removed from hulls, rather than polluting local port water and risking the spread of harmful invasive species. Captured residues are pumped into a filter unit and then deposited into dedicated drums onshore, which are collected by a locally-approved environmental waste disposal company. The effectiveness of HullWiper's filter system in cleaning the waste water has been verified by AMT Environmental, an environmental analysis and consulting professional. A clean hull also improves a vessel's speed and reduces carbon emissions.

HullWiper sprays adjustable high-pressure seawater jets directly onto a ship's hull at a very high velocity to dislodge waste materials, without using scrubbing, harsh chemicals or abrasive materials required for traditional methods. Unlike traditional brush cleaning, Hullwiper uses high-pressure jets for cleaning, thus leaving expensive antifouling surfaces smooth, intact and undamaged. The use of high-pressure jets for cleaning ensures that HullWiper does not damage the ship's expensive antifouling coatings.
