Diving inspection of hydraulic structure is a set of special technical works performed by divers during the construction of hydraulic structures (to determine the position and condition of underwater elements of the structure) or during operation (to identify damage). When examining the underwater part of hydraulic structure photo and video recording of the work is performed. In addition, the company performing the work must have certification. Specialists of “Diving Marine Service” have all the necessary permits for underwater inspection of hydraulic structure in Ukraine.
