DOF Subsea, Sonardyne, 2G Robotics, and Seatronics successfully demonstrated a new underwater surveying technique that could significantly shorten the time needed to map underwater structures and offshore sites.
The new technique uses a 3D laser scanner fitted to an ROV to create highly detailed, point cloud images of subsea assets and environments. By combining the 3D laser data with precise underwater acoustic and inertial navigation information, it is now possible to generate centimetre resolution engineering models from which accurate measurements can be instantaneously and repeatably captured.
