ABS and Fleet Robotics Partner on Autonomous Hull-Resident Robots for Continuous Cleaning and Inspection

The American Bureau of Shipping (ABS) and Fleet Robotics signed a Memorandum of Understanding (MoU) at Singapore Maritime Week 2026 to collaborate on autonomous robotic systems designed to permanently reside on ship hulls for continuous cleaning and inspection — a shift from the current model of intermittent dry-dock-based hull maintenance to always-on, in-water monitoring. Fleet Robotics develops vertical-climbing robots that remain on the vessel structure, performing cleaning and technical monitoring tasks on a continuous basis. By preventing biofouling from accumulating on the hull, the system aims to maintain optimal hydrodynamics throughout the vessel's operating cycle — directly reducing fuel consumption and extending the intervals between dry-dock visits. The classification society signal: The most important element of this partnership is not the robots themselves — it is ABS's involvement in establishing the standards and frameworks needed for the maritime industry to adopt autonomous hull maintenance with confidence. The collaboration will include assessing the suitability of robotic systems for inspection tasks, validating the quality and integrity of sensor data and imagery for class use, and identifying pathways to integrate robotic inspection into existing class, regulatory, and owner/operator workflows. Patrick Ryan, ABS Senior Vice President and Chief Technology Officer, described the collaboration as being about more than innovation — it is about working to establish the standards needed for confident adoption. Sidney McLaurin, CEO of Fleet Robotics, framed the shift directly: the future is one where hulls are continuously monitored, not intermittently inspected. By enabling in-water inspection and unlocking a new layer of high-quality data, operators can transform how they make decisions around performance, maintenance, and safety. The critical step is ensuring that the data produced by these systems is trusted, standardised, and accepted to support and enhance class inspections. Why this matters for ship managers: Hull condition is directly tied to fuel efficiency, CII compliance, and dry-dock scheduling — three of the highest-cost items in fleet management. A vessel with clean hull surfaces can reduce fuel consumption significantly compared to one carrying biofouling, and the difference compounds across a fleet over a reporting period. Autonomous hull-resident robots that maintain optimal hull condition continuously — and generate class-grade inspection data while doing so — would change the economics of hull maintenance from a scheduled cost centre to a continuous optimisation process. The fact that ABS is working on the regulatory and class frameworks means this is moving toward operational deployment rather than remaining a technology demonstration.
