UNDERWATER INSPECTION SERVICES
For Inspection work we utilize the Video Ray system. The Video Ray is a small tethered submersible craft incorporating a high gain colour video camera looking forward and a rear facing black and white camera for navigation aid.
Vertical and horizontal thrusters move the neutrally buoyant vehicle within the reservoir. The power and control tether is also neutrally buoyant resulting in a extremely manoeuvrable and stable camera platform.
The entire submersible is approximately 300 mm long and 250 mm dia which means that the unit can be sailed into feed and outlet structures and the like with impunity.
The camera lights are sufficiently intense to allow the unit to work in pitch black conditions. Depths of up to 150 meters are attainable which means that the units can be also employed to examine structures in Dams.
The Video Ray weighs only approximately 4.5 Kg and can be employed by one man. Operation speed is up to 3 to 4 knots maximum.
The unit operates on single phase 240 volts and can be run from a generator, or inverter and batteries, if necessary.
Up until now, inspections have usually been combined with cleaning to avoid mobilization costs for diving teams. The VoR Underwater Inspection Service now means that quick cheap and thorough inspections can be made as often as necessary, without combining inspections with cleaning operations.
