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. Sensing systems based on Brillouin and Raman scattering are used, for example, to detect pipeline leak-ages, to verify pipeline operational parameters and to prevent failure of pipelines in-stalled in landslide areas, to optimize oil production from wells, and to detect hot spots in high-power. The monitoring of temperature profiles over long distance by means of optical fibers represents a highly efficient way to perform leakage detection along pipelines, in dams, dikes, or tanks. Different techniques have been developed taking advantages of the fiber geometry and of optical time. It can detect pipeline leakage, ground disturbances, manual and machine excavation, theft, hot tapping, and vehicle movement immediately. Pipelines constitute an efficient solution to natural oil and gas transportation which would otherwise require thousands of tanker trucks on a daily basis.
