In-water survey (in-water inspection) includes checking the hull paint, checking for damage to the hull of the ship after a possible collision, Underwater Thickness Measurements (ultrasonic) of the hull plates in case they need to be changed, inspection and repairs of the propeller, inspecting of sea chests, and inspection for cracks. Throughout the course of services of the in-water survey (in-water inspection), photos are taken and videotaping is carried out, in order to assess the overall condition of the hull or of the area which was inspected.
The in-water survey (in-water inspection) of a ship does not require removal of the vessel from the water (dry docking). This means a quick inspection and management of any problems and a much lower total cost, since dry-docking is very expensive and the ship does not go off “service”.
