Spot gas leaks from the air.



Al Hosn Gas reached out to find a more efficient way to scan the plant for gas leaks

At an Infrared Training Center (ITC) session in October 2014, we met with Inspectahire, one of the leading companies offering inspection and testing services focusing on remote visual inspection (RVI). At that time we had already been working with FLIR building dedicated UAV systems around their sensors, such as the T-Series and GF-Series. Inspectahire talked about their latest project on a natural gas processing plant in Abu Dhabi, the Al Hosn Shah Plant. The plant purifies raw natural gas by removing certain contaminants. These contaminant gases are often very dangerous for human exposure and therefore, gas pipelines and other infrastructure need to be carefully monitored for leaks.

“Some gases are very poisonous, corrosive, flammable, and explosive,” says John Rennie, Operations Director at Inspectahire, “The company had been using so-called sniffers to detect gas leaks, but this is not an efficient way to cover such a vast network of pipelines, and it is very unsafe for the operator. That’s why Al Hosn Gas reached out to us to find a more efficient way to scan the area for leaks.”

World’s first airborne optical gas imaging solution

While discussing the Al Hosn Gas project, both companies decided to bundle their knowledge in the field of optical gas imaging and aerial inspection resulting in our world’s first airborne optical gas imaging solution based on the FLIR G300a camera.

In the presence of some members of Al Hosn Gas’s integrity management team, we organized a demonstration with the Sky Eye UAV and an FLIR G300a optical gas imaging camera near the FLIR offices in Sweden. The test flight went very well and the Al Hosn Gas team decided to have another test flight at the Abu Dhabi plant to further convince the management team of this solution. “Also here, the test was very convincing, ” says John, “We placed a leaking gas bottle on the ground and were able to monitor very accurately from the air with the FLIR G300a. This convinced the management team to have a test flight over the red zone too. And although we did not actually find a gas leak there, we can call this flight a success.”

Scan hazardous areas without any risk for human operators

Gas plants are usually very wide, so with Sky Eye solutions you are able to scan these large areas very efficiently and provide a good overview. We can help you take you to places that are hard to reach or that would take a lot of effort to go to. Gas processing plants usually have risky areas, like the red zone at the Al Hosn Shah Plant. Optical gas imaging cameras like the FLIR G300a can scan these hazardous areas without any risk for human operators.
