Micro ROV Services can provide an inspection service to local authorities that will:

• Reduce safety exposure
• Reduce costs
• No water contamination issues
• Prevent supply disruptions
• Maintain the authorities positive public perception

For potable water tanks we can achieve this is by:

• Inspecting without draining
• No people inside the tank – positive safety impact
• Top to bottom record of internal surfaces
• NDT - steel corrosion and concrete deterioration testing

For fresh water reservoirs we can achieve this by:

• Inspecting without draining
• No need to use divers – positive safety impact
• Top to bottom record of all underwater surfaces
• NDT - concrete deterioration testing
• Locate foreign objects in the reservoir
• Inspecting inlet and outfall pipes

For hostile environments we can:

• Inspect in various fluids other than water
• Inspect hazardous water areas, polluted, acidic or nuclear
• Inspect where there is risk of explosives
• Inspect where access is difficult or impossible

Micro ROV Services ROV is extremely effective for inspecting potable water tanks and pipes – without the use of divers and from a comfortable position on dry land without the need to drain water tanks or reservoirs. In fact, draining creates problems instead of solving them. If a tank or reservoir is drained the upper levels cannot be inspected without ladders, scaffold or some other method of getting people up to the higher levels, all creating unnecessary safety hazards.

Instead, using the ROV provides detailed and close up video of all levels, top to bottom. It also eliminates the risk of human contamination and exposing divers to unsafe conditions. The submersible swims through the tank and surveys the roof, seams, standpipes, and structure with ease while capturing valuable video footage.

The ROV is also effective in inspections of larger submerged pipes associated with tanks and dams. The pilot can fly the ROV along or inside the pipe checking for leaks as well inspecting the integrity of welds.

Micro ROV Services ROVs makes tank and reservoir inspections safer, complete, more affordable, and more frequent while stretching budget dollars to go farther

VideoRay has a long history of use in nuclear environments and has most recently been selected for inspection tasks in nuclear fuel storage ponds at power stations around the UK. This is a corrosive and hostile environment where it is not possible to deploy divers, and where a lot of inspection equipment would not be able to survive the extreme conditions.

Robert Wade from Magnox South commented: “I just wanted to let you know that the VideoRay is holding up well. Approximately 145 wet hours in the pH 11.4 water, no way of telling how much radiation dose it has received total but its still giving us a great picture. Around here we believe its worth it’s weight in gold!”

Guayaquil, Ecuador – Darwinvest Logistica Submarina (Submarine Logistics), recently used their VideoRay for a long range aqueduct inspection. Before hiring Darwinvest, Interagua utilized crawler and hydrophone technology to inspect the long aqueducts for leaks, with uneven results. With the Videoray, in only 6 minutes, Darwinvest efficiently inspected one 135 m (405 ft.) section of the aqueduct for leaks.

The Videoray Micro ROV

Weighing in at only 4.8 kgs (10.6 lbs) and being only 36 cm (14.2") long and 27 cm (11") wide the Pro-4 is small, light and easily deployed. In fact it is literally "throw it in the water. At only 21cm (8.5") high it can fit easily into most submerged pipelines, intakes or outfalls and spaces which are unreachable by a diver.

Small but powerful the Videoray Pro-4 can travel at 4.2 knots, see with the high resolution TV quality camera under the bright illumination of two Halogen lights. If the water is murky, there is the Blue View sonar sweeping the area and showing in sharp relief what’s ahead.

Found something? if it's small enough the manipulator can pick it up, if not the smart tether allows us to position it for later recovery by divers.

Want to measure or test something? the range of accessories allows on the spot testing of cathodic protection, determine metal thickness, detect radiation, sample water quality, and take measurements with a laser.

The ROV is a boon to the underwater world – for photographers, scientists, environmentalists, search and rescue, law enforcement, customs and excise, dam inspections, tank inspections, commercial and offshore oil and gas installation and monitoring, fisheries, recreational divers, hull inspections for yachties and commercial shipping, inspection of wharves, piers, moorings and harbour facilities and many more uses which are being discovered daily.
