Inspections of concrete hull exteriors are generally performed during low tide conditions. Many vessels, especially ones in deep berths, may require removal of marine growth prior to the inspection. Such removal of marine growth should be performed no more than two weeks ahead of time. A high definition video camera is used, the inspector narrates his findings as the inspection proceeds, and the video is shared via a link on YouTube.
Interior concrete hull inspections are not dependent upon low tides but can be complicated if performed during or soon after heavy rains. Rainwater intrusion can sometimes be difficult to differentiate from seawater intrusion. Salt residues from previous sea water instances or other minerals occasionally mix with fresh water and create a moisture or standing water area which tests as being salty. Difficult access either from construction or clutter can hamper inspections. As with the exterior inspections, a high-definition video is created with running narration of any findings and put up, usually privately, on YouTube.
