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.
