A system comprises a positively buoyant remote operated vehicle (ROV) 1 for detecting surface defects of an underwater structure, the ROV comprises a shell 12 having side edges that fit into and conform with a frame 11. The system further comprises a buoy 101 comprising an upper anti-swing device which cooperates with an anti-swing base 16 arranged on the robot. The ROV further comprises a self-unhooking device 2 comprising a buoyancy feature, which is unlocked when the ROV is submerged. The self-unhooking device comprises a fixed part fixedly attached to a steel cable attached at a shore station, and a movable part that is fixedly attached to the robot. After deployment, the fixed part of the self-unhooking device is retracted to shore via the steel cable and for recovery the fixed part is fed to a buoy along an umbilical 100 to dock with the movable part.
