Pipeline Leak Detection using Distributed Fiber Optic Sensing

Based on continuously improved state of the art for design and operation of pipelines the number of pipeline leak incidents could be reduced considerably. However, quick leak detection and localization still are the key to minimize the impact on population and environment. Various leak detection systems for enhancement of the standard computational monitoring systems are available. Out of these distributed fiber optic sensing has proven to be very well suited for pipeline monitoring, as a single sensor cable can cover up to 30 kilometers of pipeline and a leak can be detected with a few meters precision. Short overviews of the basic principles for distributed fiber optic sensing systems as well as about their application to pipelines are provided.
