Remote Operated Vehicle video inspections


Assessment of reservoir dam walls, water tanks, underground service reservoirs and flooded tunnels, adit wells and shafts.

We offer a specialist survey service using a Remote Operated Vehicle (ROV) which allows underwater inspections of:

  • Flooded tunnels and adits wells and shafts
  • Reservoir dam walls
  • Water tanks
  • Underground service reservoirs

Narrow access ROV for limited access space
Still and video images are viewed on screen by the ROV operator
Narrow access ROV
  • Maximum depth of 305m.
  • Video images are recorded onto both DVD and hard drive.
  • The use of the ROV greatly reduces the health and safety implications of using specialist divers by allowing an initial survey of the hazards before divers enter the water, or even negating the need for diver entry at all.
  • The ROV can be used with a sonar attachment which provides measurements of well or shaft diameters, tunnel widths tank sizes and locations of internal supports. (Tunnel heights are measured with the ROV depth readings.)
  • A narrow access ROV, for smaller access holes, is also available. Please see specifications below.
