Offshore mooring chains are critical components for floating structures such as oil platforms and wind turbines, yet they face degradation from corrosion, fouling, and mechanical wear. Current inspection methods are limited, often relying on manual measurements of single links, which lack scalability and precision. This project, a collaboration between OceanTech AS, Equinor ASA, and SINTEF, introduces an autonomous robot designed for the inspection and maintenance of mooring chains. Equipped with advanced 3D imaging and cleaning systems, the robot performs sub-millimeter measurements and surface roughness analysis to enable condition-based maintenance. The system has been validated in turbid underwater environments and is scheduled for deployment on the Troll platform, marking a significant step toward safer and more sustainable offshore infrastructure management.
