The energy industry is booming. By 2025, liquid fuel consumption is set to rise by 1.5 million per day, and natural gas consumption – to over 4370 bcm. Such dynamic growth requires reliable infrastructure. The key to achieving this durability is regular asset inspections.
Using industrial-grade drones, you can inspect assets at height and access remote, potentially dangerous areas without putting personnel at risk. By combining advanced sensing technology with specialized testing tools, drones can reduce inspection times in half and provide you with a continuous stream of asset condition data.
If you want to expand your fleet, here are the best drones for oil and gas inspections, available today.
Best Storage Tank Inspection Drones
Storage tanks are susceptible to corrosion and cracking due to accumulated sludge, condensation, pressure fluctuations, and bio-agents in some fuels. Monthly and yearly storage tank drone inspections help detect issues early and avoid costly downtime.
Drones can survey external walls and easily enter confined spaces, eliminating the need for
rope access, scaffolding, and asset shutdown. The advanced imaging technology and mountable NDT probes make tank drone inspection more thorough, cost-effective, and rapid.
Here are our top three tank inspection drone picks.
Voliro T
Voliro T’s specialty is non-destructive testing of assets at height. A three-tiltable motor design, allows the drone to approach structures from any angle and apply stable force during interactions. Thanks to a robust body design, Voliro T remains stable even with wind up to 8 m/s and operational in temperatures between -10 °C to +40 °C.
The drone features a 17K lumen light, an inbuilt 4K inspector camera with a horizontal FoV of 80°, and AI-assisted flight controls, plus 6 LiDAR and vision-based velocity sensors to prevent collisions and operate even without GPS. So you can safely cruise around complex structures and access the insides of the storage tanks.
Voliro’s main competitive advantage is the unmatched selection of NDT payloads, six in total — all available as part of the subscription. The three top picks for storage tank inspections are ultrasonic testing probes:
Standard UT probe measures wall thickness and locates internal defects with the range of 4-150 mm and resolution of 0.02 us.
High-term UT probe enables live A-Scan of assets heated up to 260°C, eliminating downtime.
EMAT probe measures thicknesses down to 2mm and with 0.002 in resolution without direct contact, even on rough or coated surfaces.
With Voliro’s technology, you can collect over 200 accurate readings of walls, roofs, and floors per hour during the drone tank inspection — much more than with conventional NDT tools. Fast setup time, AI-assisted inspection modes, and high accuracy also cut down inspection times. Our customers can fully inspect 5-10 storage tanks per day.
