Scour Protection Photogrammetric Inspection of Cable-Stayed Bridges Piers

BM was assigned the task of locating and retrieving an anchor along with two lengths of chain that had become lost in a complicated rocky seabed in the Aegean Sea. To search for, detect, and determine the geolocation of the anchor and chain, an ROV equipped with advanced detection sensors (including Multibeam Imaging Sonar and UHD cameras) and navigation equipment (USBL and DVL) was utilized. A 3D model of the anchor and chain layout on the intricate rocky terrain was developed to aid our divers in executing a successful salvage plan.
