CRABI Robotics

The Crud Removal Autonomous Brushing Instrument is designed to remain attached to a cargo vessel and groom its submerged hull while the ship is underway. Repeated light brushing removes biofilm before heavier fouling develops, while integrated inspection produces condition records without scheduling divers, dry-dock time or a separate port-cleaning visit.

CRABI targets drag reduction and coating preservation through frequent maintenance rather than occasional aggressive cleaning. The company estimates that clean-hull operation can reduce fuel use by 9–17%, depending on vessel conditions. C Transport Maritime is both an investor and pilot partner, and the companies are preparing live in-transit demonstrations; the system therefore remains at the sea-trial stage rather than an established fleet-wide service.
