Monitoring and Inspection of Hydropower Stations and Dams with Unmanned Underwater Vehicles
The flooded areas of hydropower stations and dams are typically only monitored by measuring the geodetic positions, leachate and visual inspections of the inspection chambers.If any problems are found during these operations, usually the damage is already massive.Human inspections of the water exposed side of dams are only possible with divers for the upper water column or by a drawdown.Both operations are cost intensive, in addition the inspection is sometimes risky for the divers.Preventive measures like the underwater monitoring and inspection of the flooded infrastructure help to prevent major harm and to reduce the danger for humans.The Fraunhofer IOSB-AST has been working for more than one decade on underwater vehicles and the sensor integration for such underwater tasks.In this paper the current state of science and technology for the underwater monitoring and inspection will be presented and discussed.The paper describes several recent developments such as the vehicle guidance methods for automatic inspection of underwater infrastructure (harbors, offshore wind energy generators, dams).Autonomous inspections require underwater vehicles equipped with accurate navigation systems resulting in expensive underwater vehicles while manual inspections are typically conducted with remotely operated vehicles.
