Products Pipeline Monitoring and Leak Detection

Fiber Optic Pipeline Monitoring 

The Praetorian Fiber Optic Sensing System can be installed on a buried or unburied pipeline. It can detect pipeline leakage, ground disturbances, manual and machine excavation, theft, hot tapping, and vehicle movement immediately. The fiber optic pipeline monitoring continually monitors large spans of pipelines, looking for vibration and temperature changes. Once detection occurs, the system alerts the operator or security personnel to the exact location of the disturbance in the pipeline. This type of real-time intelligent monitoring is critical to operating efficiently and protecting valuable assets. Hawk Fiber Optics can assist you with all your needs as a real-time pipeline leak detection sensing system provider.

Principle of Operation

The Praetorian Fiber Optic Sensing System emits a laser pulse down a fiber optic cable to measure vibration and temperature and the position of that vibration and temperature. Using a combination of Rayleigh backscatter, Brillouin Backscatter*, and time of flight, Praetorian determines the presence, location, intensity, and frequency of vibrations and temperature changes along an optical fiber in real-time. Rayleigh Backscatter responds to physical vibration imparted on the fiber by disturbances to the application. HAWK's signal analysis software allows the Praetorian System to determine the most likely origin of the vibration quickly and report any erroneous signals of potential issues with the pipeline to maintenance personnel. Brillouin Backscatter* responds to shifts in environmental temperatures and is used to detect the temperature drop associated with the reduction in fluid pressure caused by the leak, taking advantage of the Joule-Thomson effect.
