GAC EnvironHull has launched HullWiper, a new innovation offering diver- free, cost effective and eco-friendly underwater hull cleaning. The compact, remotely-operated vessel cleaning vehicle is capable of cleaning up to 2000sq m of hull per hour without damage. After cleaning, vessel speed and performance is significantly improved as a result of reduced resis- tance, which in turn decreases carbon emissions and fuel consumption. HullWiper cleans the vertical sides of a VLCC (approximately 8000sq m) in seven hours, half the time taken in using conventional cleaning methods with divers. The machine enables hull cleaning to be carried out alongside during loading or discharge. www.gac.com/hullwiper
