SeaRobotics SR-HullBug

The SR-HullBUG is a semi-autonomous cleaning system that uses light brushes to groom a ship's hull and remove the early signs of biofouling.

The gains associated with a smooth hull are immediate, both in terms of a ship’s efficiency and its environmental footprint. Biofouling results in exponential hydrodynamic drag, which equates to mounting fuel costs and increased greenhouse gas emissions. Furthermore, traditional cleaning methods—divers with abrasive brushes and tools—tend to degrade the ablative coatings designed for anti-fouling, which inevitably leads to a period of dry-docking for recoating. Not only is this a costly overhaul, it’s an avoidable period of inactivity. The solution is SR-HullBUG.
