34 MAY 2018 COATINGSPROMAG.COM what's happening at all times. is web-driven innovation also reduces the need for increased or expen- sive on-site manpower for tank operations. ough tank inspection reflects only one area of ROV use, the concept of live remote control is somewhat like how the world 's technologically most advanced militaries have, for years, operated battlefield aerial drones from safe locations outside the theater of war. • Utilize sensors: Most ROVs already come equipped with such features as a high-definition (HD) camera, high intensity light-emitting diode (LED) bulbs, sonar, laser scaler, and grabber arm. The cameras paired with LED lighting are used for visual inspection and documentation while proving to be especially useful in waters along the bottom of the tank. A grabber arm can be used to retrieve foreign objects from the water around the inside of the tank. In the case of sensors, strong temperature differences between a tank's bottom and top generally indicates a slowdown in proper water circulation. Temperature sensors on an ROV can detect these changes. Additionally, an ROV 's ultrasonic thickness gage, a form of underwater nondestructive testing equipment (NDT), allows inspectors to check the thickness of a tank's walls without harming either the metal or the coatings. This ensures that the structural integrity of the asset isn't compromised. • Check sediment levels: All water tanks will naturally collect sediment over time. To best determine how healthy the water in a tank is, the inspector will need to check the sediment inside. The higher the levels, the greater the likelihood that there is bacteria existing in the tank. As this sediment builds up, it must be periodically cleaned, which is similar to the bottom of a pool. Use the high-intensity lights and high-resolution camera on an ROV to get a good look at the bottom of the tank before and during sediment removal. Some underwater ROVs are even designed to aid in the cleaning process directly, further reducing the risks involved with prolonged dives. Investigate that option if it's a feature you'll need. • Explore all angles: Using features such as lateral thrust and 360-degree underwater cameras, your ROVs can explore weld seams and better determine any compromised areas, including on a tank's ceiling. Be sure to explore all angles inside the tank and not just the top and bottom, for example. • Clean, pack up, and analyze: ROVs tend to be made of metal and plastic, and they should require little clean- ing, even after being used during an inspection job. But be sure to follow the manufacturer's direc- tions to keep your ROV working at peak performance every time. For example, a water solution mixed with bleach may be used to remove any bacteria that collected on the vehicle. Remember to place specific ROVs in only one type of water (e.g., potable) at a time. Once the ROV is cleaned and packed up, assessment teams can work to analyze data stemming from live remote viewing, live remote control, or on-board video recording. What's Best for You ere are many ROV options out there these days, but they're not all created equal. If you're going to invest in an inspection-class ROV, be sure to get the one that fits your needs best. And then learn how to use it properly.
