ALMA
AERIAL LASER METHANE ASSESSMENT
AERIAL LASER METHANE ASSESSMENT
Aircraft laser detectors for operational inspection of extended aboveground and underground gas pipelines for methane leaks
ALMA (Aerial Laser Methane Assessment) is designed for operational diagnostics of extended gas transmission and gas distribution facilities for leaks. Is used for exploration of gas fields. Can be installed on a helicopter or light-engine aircraft.

ALMA advantages
New airborne inspection capabilities
Works where land inspection is impossible
With ALMA, you can thoroughly survey a section of a gas pipeline or other extended gas infrastructure facility in places, access to which from the ground is impossible or restricted.
Faster than
on the ground
on the ground
ALMA diagnostics is carries out at an average speed of 100 km/h allowing to survey gas pipeline sections with a length of up to 600 kilometers per day.
Cheaper than on the ground
Improved efficiency of remote ALMA inspection compared to conventional land-based gas pipeline diagnostic methods makes this process as economical as possible.
How It Works?
ALMA is a system of airborne surveying of natural gas pipelines and storage facilities. The detector operation principle is based on diode-laser spectroscopy, which provides high reliability, accuracy and selectivity.
The device is fully automated and can continuously work without an operator, while storing the results in computer memory. The detector includes a GPS system that determines the flight route coordinates and leak points. Upon leak detection, the operator receives a light and sound signal, and the monitor displays a photo and a Google map of the leak site.
The detectors are designed for operation in temperate and cold climates; they comprise an optical unit and an electronics case.

FAQ
Honest answers to important questions
No, each device is designed to detect a specific gas. This provides a 100% probability of leak detection of methane and not any other gas.
Laser radiation is completely safe, it corresponds to class 1.
Yes. It is an active device, it emits at a certain narrow wavelength, so it does not need additional signal sources.
No. The detector contains a reference container with methane inside and calibration is performed at each start-up and during operation.
The detector does not need to be verified because it is not a measuring tool.
It works remotely. There is no direct contact with the hazardous environment.
According to our experience, in one working day, our experts survey up to 500 miles of a pipeline on average. This is about 5,000 miles in two weeks of flights.
Yes, for R44 and B206 helicopter models.
