Published purpose

Preventative leak detection is a growing field in the pipeline monitoring industry. Distributed fiber optic sensing is a major technology platform for this service. Hifi's high fidelity dynamic sensing system (HDS) is capable of sensing acoustics, temperature, strain and vibration in or near a pipeline in very high fidelity. The system, which can monitor very long distances, has been successfully used for leak detection in land and offshore pipelines in Canada and the United States, as well as in other international regions such as South America and Europe. A variety of artificial intelligence / machine learning based software methods such as leak signature classification, flow anomaly localization, and observing major changes in the pipeline acoustic propagation model, are being developed for leak detection. Results from independent lab tests where the efficacy of the system in detecting pinhole leaks with pressure ratings as low as 5 psi and flow rates down to 0.1 LPM has been proven. Hifi's HDS technology can help make pipelines safer and represent an excellent made-in-Canada solution to a very relevant Canadian problem.
