VIBRATORY PIPELINE DIAGNOSTIC SYSTEM AND METHOD
First Claim
1. A vibratory pipeline diagnostic system (100), characterized by:
- 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), with the processing device (111) being 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.

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.

16. A vibratory diagnostic method for a pipeline, the method characterized by:
-
vibrating a portion of the pipeline; receiving a vibrational response to the vibration; determining a resonant frequency of the portion of the pipeline from the vibrational response; comparing the resonant frequency to one or more previous resonant frequencies of the pipeline; and indicating a fault condition if the resonant frequency differs from the one or more previous resonant frequencies by more than a predetermined frequency tolerance. - View Dependent Claims (17, 18, 19, 20, 21)
