DAM INSPECTION
Thousands of dams around the world are of aged construction and built to standards that have since been superseded.

All must cope with natural disasters and increased loads from a growing demand worldwide.
Underwater vehicles are ideally suited for the location and identification of defects, to help maintenance planning and monitor trends in condition.

Advanced imaging and filming technology matched to precise manoeuvrability and power means that vehicles can work at complex tasks in difficult conditions for long periods.
Operational tasks include:
  • Locate, log, film and measure cracks.
  • Create 3D Digital Terrain Models of structures, foundations and spillways.
  • Establish Trash Rack blockage volumes for removal.
  • Inspect mechanical systems for damage or malfunction.

Saab Seaeye Falcon - dam inspection vehicle
Cougar XT Compact - a hybrid
AUV/ROV that has 360 degree manoeuvrability
and can swim over 12 kilometres down a tunnel
where it can navigate rises and falls and tight
bends, and keep working for 10 hours.
Falcon - a small yet powerful ROV, ideal for difficult to access locations. It can be fitted with a range of observation and survey systems and has an excursion length of 1000 metres. It can work in zero visibility and in currents. It can be manhandled down inspection hatches and can navigate along tunnels through rises and falls and round tight bends.
System options include:

Real time high bandwidth visual data
3D Digital Modelling
System options include:

3D Digital Modelling
HD video
Laser image scaling system
Manipulator for obstruction removal
