What are the benefits of using a ROV for (drink)water tanks?

Written by Karst Beens

How can the drone / robot best be used?

Tank inspection is necessary for structurally healthy, clean and safe water tanks. Without inspections, problems can quickly arise, including sludge in the tank. This jeopardises the integrity and cleanliness of the tank.

H2O Drones offers advanced remotely operated vehicles (ROVs) to change the world of water tank inspections. The drones are proving themselves as a valuable tool for safe, accurate, clean and convenient tank inspections. Why is this so? Read on and see why underwater drones are essential for tank inspections.

See here how it is done!

 

TUNING ROV ENGINES YOURSELF!

Tank inspections can vary greatly and users may require small, precise movements and large, sweeping movements in the same inspection. Adjusting the gain control will increase or decrease the speed and steering sensitivity of the ROV, allowing operators to maximise control. The gain control can be adjusted using the two sets of arrows in the centre of the controller. Set the gain as low as 1 or as high as 12 (10%-120% power) to easily make small, precise manoeuvres or large, extended passes.

 

STABLE CAMERA CONTROL ON THE UNDERWATER DRONE:

With Deep Trekker’s innovative BRIDGE technology, underwater drones provide automated control and stability for operators, allowing them to keep the camera focused on the inspection. Easily perform vertical inspections of walls by rotating the camera while keeping the ROV in place. The 270-degree camera rotation also allows operators to quickly and easily inspect ceilings, floors and walls.

 

DOES NOT AFFECT WATER QUALITY:

When inspecting water tanks, towers and other water storage facilities, it is important to keep the water clean. One of the main advantages of using an underwater robot for inspection purposes is that they do not introduce contaminants into the water as a diver might. Prior to entering the tank, underwater drones can be fully sanitised with a chlorine solution without any negative effects on the ROV itself. Keep the water tanks clean and free from contamination!

 

LASER SCALER ACCESSORY

The laser accessory is a useful tool for understanding the size of objects or potential errors. It emits two laser beams 25mm away from the camera. The operator can then map objects, cracks or rust spots from up to 2 metres away. The lasers follow the camera as it rotates, so the beams can be viewed on the screen at all times. With these lasers, the operators can make a more accurate estimate of the size of objects in order to make a proper analysis for a follow-up plan.

PHOTO AND VIDEO DOCUMENTATION

In addition to providing live underwater images, the underwater drones can allow users to record both photos and videos during inspections. This content can be further enhanced with voice notes or titles to properly archive and present the inspections to clients. Data can be transmitted immediately and stored for analysis, where raw data can be converted to useful information. Recorded content is also useful for training and internal review processes.

H2O Drones also offers tank cleaning tools in the Netherlands, Belgium and Germany from Deep Trekker. These are designed to enable thorough and efficient cleaning without taking tanks out of service. See the DT640 Utility Crawler with vacuum and high pressure cleaning options.
