Following the expansion to Fujairah and Gothenburg, GAC EnvironHull is now offering its HullWiper underwater hull cleaning service at the UAE port of Sharjah. The HullWiper, a Remotely Operated Vehicle (ROV) underwater hull cleaning unit, uses adjustable pressure sea water jets for cleaning, rather than brushes or abrasives, causing minimal damage to the antifouling surface. Residues and harmful marine growths captured during cleaning are discarded in an environmentally-friendly manner, opposed to sea disposal performed in traditional methods.
