SeaRobotics HullBUG

Semi-autonomous underwater vehicle designed to crawl on ship hulls

The HullBUG System is a semi-autonomous underwater vehicle designed to crawl on ship hulls or other underwater structures and "proactively groom" the surface. Developed by SeaRobotics and funded by ONR, this highly automated proactive grooming (or light cleaning) process will revolutionize hull maintenance, allowing ship hulls to remain in a clean state at all times.

Description

The HullBUG System is a semi-autonomous underwater vehicle designed to crawl on ship hulls or other underwater structures and "proactively groom" the surface. Developed by SeaRobotics and funded by ONR, this highly automated proactive grooming (or light cleaning) process will revolutionize hull maintenance, allowing ship hulls to remain in a clean state at all times. 

The benefits of improved hull condition are dramatic—the estimated 5% improvement in fuel efficiency achieved through proactive grooming translates into a savings of $15 billion per year for the shipping industry worldwide as well as reduction in the 1 billion tons of greenhouse gases emitted by the fleet.
