Abstract
A vibratory pipeline diagnostic system (100) is provided. The system (100) comprises at least one vibration generator (104) adapted to be affixed to a pipeline, at least one vibration sensor (107) adapted to be affixed to the pipeline, and a processing device (111) in communication with the at least one vibration generator (104) and the at least one vibration sensor (107). The processing device (111) is configured to vibrate a portion of the pipeline using the at least one vibration generator (104), receive a vibrational response to the vibration from the at least one vibration sensor (107), compare the vibrational response to one or more previous vibrational responses of the pipeline, and indicate a fault condition if the vibrational response differs from the one or more previous vibrational responses by more than a predetermined tolerance.
