Underwater Dam Investigation

ASI provides pertinent information for dam safety assessments.  

Regular inspections can prevent dam failures. Remote technology can help.

Inspection and Maintenance are critical to the performance and longevity of underwater infrastructures.  

Measurable data, images and videos can be collected using remote technologies for condition assessment and regulated inspection reports. ASI has gained international recognition for research and development of remote techniques for underwater inspection and maintenance. We have developed methodologies of using sonar systems to capture pertinent data under flow conditions. Our team of Remotely Operated Vehicle (ROV) pilots, techniciansengineers and certified hydrographers are well-versed in the area of underwater data collection and have gained vast experience working at numerous dam sites across the globe.
