This study proposes a procedure of damage inspection for the infrastructure in the harbor. Because most infrastructures in the harbor are submerged under the water the damage inspection is very difficult to process. Normally, divers with special scheme of damage inspection are required and the cost is very expensive. Therefore, a two-stage inspection strategy is proposed. After the first stage of inspection the more detailed second stage inspection will be requested dependent on the examination results. In the second stage of inspection particularly, it is focused on the wharf structures of steel-sheet pile type, where the related items are identified corresponding to the characteristics of the structural system.
