ASI-Marine unveils new tool for hydropower project tunnel inspections

A new remotely operated vehicle (ROV) from Canadian manufacturer ASI-Marine Technology is capable of giving a comprehensive view of partially-flooded waterways.

Called the “Above & Below Inspection System”, or “ABIS”, ASI Marine said its new ROV uses top-side data with LIDAR while simultaneously inspecting surfaces below the waterline with profiling and imaging sonar. Data gathered is then processed to provide a comprehensive three-dimensional view.

Additionally, ABIS is capable of providing high-definition video footage and digital photographs, environmental data and more due to the modular construction of the system.

The company said the ABIS vehicle would be of particular use by hydropower project operators looking to inspect tunnels without taking their plants off line.

ASI-Marine Technology will be exhibiting at HydroVision International 2014 in Booth No. 733.

HydroVision International, now in its 20th year, is the world’s largest hydro event. This year’s conference and exhibition takes place July 22-25 at Nashville’s Music City Center.
