Zupt’s 3D Recon is used for contactless mooring line inspection as a more efficient alternative to the industry convention of “go, no-go” calipers for wear and simple ROV video footage. Easily manipulated by either a Work Class or Inception Class ROV, 3D Recon quickly models the mooring line or chain links to a pixel resolution of less than a millimeter to provide highly accurate models to measure chain-link wear without physically contacting the mooring line. Zupt’s deliverable provides data to be stored and compared with future surveys to automatically detect wear rates of the mooring line.
