Pilot operation of ZALA unmanned systems for methane detection

The ZALA unmanned system was put into pilot operation at the gas transmission system facilities of Gazprom transgaz Ekaterinburg.

The work was carried out on behalf of PJSC Gazprom, the main objective being to ensure that the system functionality meets the company's requirements and to confirm its ability to promptly detect methane leaks on an industrial scale.

The infrastructure survey was conducted using a ZALA 421-16E unmanned aerial vehicle (UAV) at an altitude of 100 meters. A special payload—a DLS-LA methane detector from Pergam Engineering JSC—allows for in-flight detection of methane leaks thanks to the instrument's high stabilization and allows for their isolation from natural background noise. Leak location data is displayed on the ground control station's monitor in real time.

As part of the pilot operation, the flight team surveyed more than 1,000 kilometres of gas transmission system communication corridors. The result was a proven technology ready for implementation.

Employees of Gazprom transgaz Ekaterinburg positively assessed the performance of ZALA unmanned systems. According to the company representatives, this is a cost-effective and efficient alternative to manned aviation.
