  • Patent number: 9200744
    Abstract: A tracking system for use with a pipeline includes a scraper having signal generation capability for generating acoustic signals, a plurality of acoustic pressure sensors positioned at intervals along the path traveled by the scraper, and a plurality of local processors positioned at intervals along the path traveled by the scraper. Each of the local processors is in communication with a respective acoustic pressure sensor. A central processor is in communication with the local processors and determines the location of the scraper using time-stamped acoustic signals received by the pressure sensors and a speed of sound in a fluid within the pipeline.

  • Patent number: 8425683
    Abstract: A method for tracking a scraper within a pipeline has the steps of moving the scraper along a path in the pipeline such that the scraper produces an acoustic signal, sensing the acoustic signal as produced by the scraper by at least a pair of acoustic sensors positioned in spaced relation along the pipeline, time-stamping the sensed acoustic signal, and calculating a location of the scraper based on the time-stamped acoustic signal. The acoustic signal can be a transient pressure wave produced by the movement of the scraper or a pressure signal produced by a mechanism positioned on the scraper.

  • Patent number: 8346492
    Abstract: A system for detecting and locating leaks includes a pipeline, strain sensors positioned on the external surface of the pipeline, acoustic pressure sensors positioned at intervals along the pipeline, local processors connected to the strain sensors and acoustic pressure sensors, and a central processor connected to the local processors. The strain sensors measure a strain on the external surface of the pipeline indicative of changes in the pressure of the fluid within the pipeline. The acoustic pressure sensors sense acoustic signals within the pipline. Sensed acoustic pressure signals and sensed strain measurements are compared to each other and to stored profiles to detect and locate leaks.

  • Patent number: 6668619
    Abstract: A method and apparatus is provided for detecting and locating leaks in a pipeline. Pattern match filtering is used to reduce false alarm rate, increase sensitivity and improve leak location accuracy, while quickly detecting leaks by the acoustic signal generated from a leak event in pipelines containing gas or liquid under pressure. The pattern match filter technique detects a pressure wave generated by a leak, but discriminates against background noise and pressure disturbance generated by other non-leak sources that might otherwise be detected as a leak. The pattern match filter derives a sharp peaked output from the signal of the expansion wave which allows for a distinctive point of reference for a time stamp. This provides for improved accuracy in leak location calculations. The pattern match filter is incorporated into site processors located at multiple points along a pipeline, and at a central node processor which receives data from all site processors.
