High Resolution Structural Inspection of Flooded Tunnel
Acquiring accurate data on the structural integrity of submerged tunnels, as well as shafts and underwater caverns, has long been a challenging and costly problem for water companies, hydroelectric schemes and mine operators alike.
Recent developments of sonar technology enable collection of 3D data resulting in an accurate profile of an underwater structure to be developed. Using high frequency, low power acoustic multibeam technology, overlapping narrow beams create a continuous 360° profile of the tunnel.
The attached article provides a case study of the use of Teledyne BlueView T2250 Multibeam Profiling Sonar technology that enabled inspection of a tunnel without de-watering.
