GAC launches eco-friendly hull cleaning solution


HullWiper is said to clean the vertical sides of a VLCC in seven hours.



GAC EnvironHull Ltd., part of global shipping, logistics and marine services provider GAC Group, has launched HullWiper, its new innovation offering diver-free, cost effective and eco-friendly underwater hull cleaning.

Despite its compact size of just 3 x 1.5 x 0.80 metres, the high-speed, remotely-operated vessel cleaning vehicle is capable of cleaning up to 2,000 square metres (m²) of hull per hour without causing any damage to antifouling surfaces.

After cleaning, vessel speed and performance is said to be significantly improved as a result of reduced resistance, which in turn decreases carbon emissions and fuel consumption. And as the system does not use divers to carry out the cleaning, the risk to life is also significantly reduced.

According to GAC, HullWiper cleans the vertical sides of a VLCC (approximately 8,000 m²) in seven hours - half the 14 hours the same job would take using conventional cleaning methods with divers.

The machine enables hull cleaning to be carried out alongside during loading or discharge, reducing or even eliminating the need for off-hire time. The entire process is in line with the GAC Group's stringent HSSE and compliance policies as well as all local and regional environmental regulations. Residues and harmful marine growths captured during cleaning are disposed of in an environmentally-friendly manner instead of being discharged into the sea as done using traditional methods.

Simon Doran, Managing Director of GAC EnvironHull Ltd, remarked: "Clean & Green is the spirit of HullWiper. In an industry that is increasingly seeking environmentally sound and risk-averse options solutions, our cleaning service ticks all the boxes."

HullWiper's innovative features have earned it permission from the Norwegian Climate and Pollution Agency KFT to perform cleaning operations within all Norwegian ports and from the UAE Environmental Department and DP World for use in inner harbours at all quays inside the port of Jebel Ali.
