Pipeline Intrusion Detection System (PIDS) installed by Cairn India Ltd. (CIL), using existing fiber optic cable and acoustic signature recognition, is one of the most efficient ways to mitigate external sabotage/threats to a long distance pipeline. The system is designed to sense the vibrations, earth movement, and other surface movements associated with such activities. It detects excavation/intrusion activities as the equipment approaches the sensing cable and pipe itself. It is also capable of accurately locating the source of ground vibrations. The system also supports leak detection and pig tracking along the pipeline. By providing an early warning and precise location of an incident, Pipeline Intrusion detection system can help responders prevent costly damages/business/safety impact. Using already existing fiber optic cables along the pipeline, PIDS is the latest proven technology which provides critical information for effective response in event of any undesirable activities along pipeline.

A perimeter intrusion detection system (PIDS) is critical for the security of a shale gas field. Among many technologies, the fiber optic sensor-based method is the most widely used, due to its passive, low-cost, long-life, and strong anti-interference ability and strong environmental adaptability. This article proposes an event detection and classification method for a fiber optic PIDS. In general, three types of features are extracted for an improved double-threshold method to improve the probability of detection. Also, the detected intrusion events are distinguished by a support vector machine with wavelet features to reduce the nuisance alarm rate. Experiments on the PIDS in Chongqing Fuling's shale gas field show that detection algorithms based on the feature of short-time energy and short-time wavelet coefficient energy are much better, and the performance of event classification is satisfactory.
