Aerial corridor surveys are now the preferred method for periodic and diligent inspections of pipelines and utilities transmissions lines. Remote Helicopters has the necessary tools to get the job done.
Natural gas pipeline owners require improved routine monitoring of pipelines for safety, economic, environmental and regulatory reasons. Leaking natural gas can cause explosions leading to the loss of life and property. Loss of products through undetected leaks dramatically reduces a pipeline operator's profitability.
The laser GasFinder is mounted on the belly of a helicopter. The measurement probe for airborne surveys has an effective path length of 2 meters. The laser probe provides continuous calibration updates. While measuring and referencing, signals are constantly compared to determine the actual concentration of gas in the probe. It is an extremely effective tool in the detection of methane. Each data point taken at 1 second intervals has an associated methane level and GPS location that can be reviewed at any time during or after the flight.
All the information gathered from the GasFinder, including GPS data is automatically recorded and stored during the flight and can be looked at in detail while the flight is taking place, or after the flight. The parameters of what is an acceptable level of methane can be adjusted at anytime so that the natural levels of methane (normally green) can be differentiated from suspected leaks (yellow or red)
The laser GasFinder is capable of detecting low levels of methane from long distances even under moderate wind conditions of up to approximately 10-15 knots (18-25km/h).
When winds reach about 15 knots (25km/h), results cannot be guaranteed and cannot be used at all above 20 knots (35km/h) due to the manner in which the gas will dissipate rapidly and become undetectable.
Yes, as long as levels within the oil have a high concentration of methane. Some crude oil may not have enough dissolved gas to be detectable when it comes out of the solution and therefore the infrared camera is used as a primary, the GasFinder secondly, and the Red Hen Video to back up all the findings.
This patented GPS recording technology unites data, time, date, and location data with audiovisual content. The content can then be imported into mapping software and distributed to your company for evaluation.
With these combined tools as well as the Infrared Camera, we can help you get those inspections done!
