Underwater Inspection Services

Tunnel & Pipeline Inspections Services

Remote Inspections provide a safer and cost-effective alternative to dewatering tunnels and pipelines. If left unattended, what you can’t see can potentially cost millions of dollars. It could be a leaky seal, loss of head pressure, damaged intake structure or rock debris in a tunnel that causes significant damage, costing millions of dollars in fines, repairs, lost revenue and a diminished reputation. Chances are that decaying infrastructure, especially when deep underwater, can go unnoticed. If an asset must be taken out of service, ASI understands that time is of the essence and commits sufficient resources to provide 24-hour continuous operations for as long as the client requires.

Underwater Dam Inspection Services

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 underwater dam inspections, condition assessments and regulated inspection reports. ASI has gained international recognition for researching and developing remote techniques for underwater dam inspection, repair and maintenance. With limited to no impact on normal plant operating conditions, ASI has developed methodologies that use sonar systems to capture and present pertinent data for asset management. Our team of remotely operated vehicle (ROV) pilots, technicians, engineers and certified hydrographers are well-versed in underwater data collection and have gained vast experience working at numerous dam sites across the globe.
