Gas Regulating Station, Kazakhstan
Project Background
As the natural gas industry continues to prioritize operational safety, digitalized maintenance, and intelligent inspection systems, traditional manual inspection methods are increasingly challenged by limitations in efficiency, safety, and inspection coverage within gas regulating station environments.
Gas regulating stations typically contain dense pipeline networks, valve groups, flange connection points, and pressure regulating and metering equipment, all of which are considered high-risk areas for natural gas leakage. Conventional manual inspection methods often face challenges in rapid leak localization and large-area inspection efficiency under complex facility conditions.
To further improve safety management standards for natural gas infrastructure, a state-owned natural gas operator in Kazakhstan deployed the BL-CH4 UAV laser methane detection system developed by BLV Technology for on-site testing at a gas regulating station.
The project aimed to verify the system’s rapid methane leak inspection capabilities under complex industrial operating conditions.
Solution Overview
The project adopted an inspection solution combining an industrial UAV platform with laser methane remote sensing technology for gas regulating station inspection operations.
Flight Platform
The project utilized a DJI industrial drone platform to perform inspection flights following standard operational procedures.
The UAV enabled rapid coverage of critical station areas, improving inspection efficiency in complex facility environments.
Methane Detection Payload
The UAV was equipped with the BL-CH4 laser methane detector based on TDLAS (Tunable Diode Laser Absorption Spectroscopy) technology.
Key capabilities include:
Long-range non-contact methane detection
Real-time gas concentration monitoring
Rapid leak localization
High-sensitivity low-concentration methane detection
Stable operation in dense pipeline environments
Project Implementation
The test was conducted at a natural gas regulating station in Kazakhstan.
The site included:
Multiple natural gas pipeline sections
Valve group areas
Flange connection points
Pressure regulation and metering equipment
These areas represent high-risk leakage points and require high detection sensitivity and precise localization capabilities.
During the test, engineers conducted UAV inspection flights across critical operational zones within the station.
Throughout the mission, the system continuously displayed methane concentration changes in real time while enabling rapid identification of abnormal leakage areas through concentration curves and visualized indicators.
Even in complex and densely distributed pipeline environments, the system maintained stable data output and reliable detection performance.
