GAC's green HullWiper system uses adjustable sea water jets to remove fouling

The first cruise vessel in Copenhagen has had its hull cleaned with pioneering ROV technology that keeps contaminates out of the water.

The hull cleaning operation for the DFDS Group’s ‘Pearl Seaways’ used GAC EnvironHull’s diver and brush-free HullWiper, the first time the technology has been used on a cruise vessel.

Gert Jakobsen, Vice President of the DFDS Group, said: “We pride ourselves on our environmental credentials, so it was essential that whatever system we chose could handle waste water and not contaminate the local marine ecosystem with debris and fouling material.”

The system uses adjustable sea water jets to remove fouling, which is not only greener, but also avoids any damage caused by brushes or abrasives to the hull.

It also collects debris from the operation for environmentally approved disposal on land, thus reducing the risk of cross-pollination of waters with alien species.

It took just 7.5 hours to complete the hull clean of the cruise ferry, which serves routes between Copenhagen and Oslo, whilst it was in dock at the Danish port.

HullWiper’s network includes ports in Sweden, Singapore, Spain, Netherlands, Norway, United Arab Emirates and on an ad-hoc basis at other key locations in the Middle East.

A clean hull brings benefits of greater safety, pollution avoidance, improved performance, reduced fuel consumption and fewer carbon emissions, as well as forming an important first impression for cruise passengers.

This latest contract marks more than 550 hull cleans carried out by GAC’s ROV technology worldwide.
