The Optical Chain Measurement System (CMS) is a ROV-deployed optical caliper imaging device, which measures mooring chain dimensions and the material condition of links. The tool is positioned on a link to capture video data, yielding near real-time measurement results. This data is processed to produce measurements of intergrip diameters and link length.
Measurement of chain dimensions is critical to confirm that chain corrosion and wear rates are within expected tolerances, and that chains maintain their minimum strength requirements throughout their lifetime.
