TECHNOLOGY AT CURRENT SURVEILLANCE INC.
Government regulations are focused on reducing green house gas emissions especially from the oil and gas, and petrochemical industries. Remote Detection Technology is recommended as the most effective technological choice for detecting fugitive emissions. Aerial Gas Leak Detection using a Tunable Diode Laser Spectroscopic technology and Aerial Visual Inspections using High Definition Multiple Zoom cameras to help identify critical deficiencies on the ground as well as on elevated structures such as Flare Stacks, Towers, and Smoke Stacks without shutting down operations. This type of inspection reduces remediation downtime during scheduled repairs and maintenance.
METHANE DETECTION
CSI Drone Services provide Methane Detection on Pipelines, Pipeline Right of Ways and Oil and Gas Production and Transmission Facilities complete with full video and accurate geo-referencing. This is a very efficient way to inspect dangerous, remote or difficult to access areas. Utilizing Tunable Diode Laser Spectroscopy (TDLS), CSI Drone Services can now detect methane gas from the air that is emitting from the ground. We do not have to come in contact with the gas to detect leaks.
TDLS in Detection Simplified Explanation: Specific light wave is emitted from the detector that is absorbed by the specific gas being targeted. In our case methane gas. The light returning to the detector is then measured and a concentration of gas detected is determined. Post Flight Analysis helps eliminate erroneous indications. With the location of the detector recorded simultaneously, the gas emission can be located within a very specific area. This reduces time drastically for remediation.
We have been able to integrate systems that assist in automated or semi-automated flight plans including altitude and paths of the aircraft to fly. This provides a more consistent scan and removes some aspects of human error that may arise while flying unfamiliar areas. The pilot does, however stay in full control of the aircraft should the need to intervene become apparent. The aerial view of the area being inspected is also an advantage to see and identify visual deficiencies, encroaching dangers and potential threats to the pipeline or facility’s integrity. Some examples would be missing signage, exposed pipeline at a water crossing, eroded drainage, soil sloughing, stressed vegetation and visible ground disturbance.
