Aquatic Robot Crawls Hulls to Brush Off Barnacles
14th March 2020
It begins with the proprietary SeaQuantum Skate silyl acrylate-based coating being applied to the ship’s hull. While this resists biofouling all on its own, it’s also designed to not be damaged by the HullSkater robot, which is the system’s other main component.
That robot stays aboard the ship full-time, in a portable station that includes a launch and recovery ramp. An internet-based system – which monitors the ship’s status and location, along with marine conditions – lets the crew know when hull-cleanings should be performed. The ship has to be anchored or docked at the time.
Once launched, the HullSkater clings to the underside of the vessel using its four magnetized wheels. Motors in each of those wheels proceed to move it along, while a rotating brush on its front end preemptively scours away the “biofilm” that forms in advance of outright biofouling.
Not quite a Roomba for the ship’s hull, but close.
