AN Aberdeen-based remote inspection technology specialist has launched the “world’s first” lightweight optical gas imaging inspection system.
Air Control Entech believes its new drone has the potential to change the way the oil and gas industry inspects its assets due to its flexibility and technical advantages.

Weighing less than 5000 grams, the unmanned aerial vehicle (UAV) is less than half the weight of other optical systems, allowing pinpoint visual accuracy of gas leak locations in the most challenging and previously inaccessible areas.
The system, which can spot leaks from more than 100m away, can be used in a variety of upstream, midstream and downstream environments including refineries, process plants and decommissioning projects such as well plugging and abandonment.
The lightweight camera with digital zoom capability and real-time data transfer provides high definition gas imaging to accurately detect leaks beyond the scope of normal human vision. Colour coding gasses can help their identification.
The system can improve process safety by reducing the risks of fire or explosion through early and fast gas detection. It can also visually scan vast areas more quickly than alternative sensing technology, which is unable to offer pinpoint accuracy of leak location.
Kieran Hope, Air Control Entech chief operating officer, said: “Our optical gas imaging system has the potential to change the way the industry inspects the safety of its assets.
“Now operators can visualise exactly where a gas leak has occurred as opposed to relying on sensing systems, which can only provide accuracy to within a 3ft radius. In environments where winds can confuse sensing systems, seeing the leak rather than relying on sniffing for it has obvious benefits.
“Visual gas inspections were previously limited to either deck level or reduced use of UAV due to camera weight and flight time capacity.
“However, operators can now reach heights and sites that were previously inaccessible and can double flight time to increase valuable data gathering.”
