The ultimate goal of this project is to detect and localize leaks in pipelines in real time. Hifi Engineering has developed distributed fiber optic sensors. Measurements are obtained at evenly spaced intervals along the pipeline (called channels). This project aims to develop data processing tools to improve leak detection and localization. Many events occur along a pipeline whose effects are registered by sensors (trucks driving by, compressors turning on, leaks). Events are registered in many channels as sounds propagate down the pipeline.
