Abstract:
A method and system for assessing the condition of a pipeline in a pipeline system is disclosed. The method includes generating a pressure wave in the fluid being carried along the pipeline system at a generation location along the pipeline system, detecting a first pressure wave interaction signal at a first measurement location along the pipeline system resulting from an interaction of the pressure wave with localised variations in the pipeline and then detecting synchronously a second pressure wave interaction signal at a second measurement location along the pipeline system resulting from the interaction of the pressure wave with localised variations in the pipeline. The method then involves comparing the first and second pressure wave interaction signals to determine a location of individual features in the first and second pressure wave interaction signals with respect to the generation location, the individual features corresponding to pressure wave reflections from localised variations in the pipeline and characterising the individual features to assess the condition of the pipeline.

Claim (Index 4):
The method as claimed in  claim 3 , wherein determining which side of the generation location the localised variations are located comprises:\n selecting a measurement location to be a reference measurement location, the reference measurement location not located at the generation location; for each remaining measurement location determining whether each remaining measurement location is located:\n on the same side of the generation location as the reference measurement location; \n on the opposite side of the generation location compared to the reference measurement location; or \n at the generation location; \n applying a negative time shift (backward in time) to the respective pressure wave interaction signal for those measurement locations located on the same side of the generation location as the reference measurement location, the negative time shift corresponding to the time interval that the pressure wave takes to travel from the generation location to the respective measurement location; applying a positive time shift (forward in time) to the respective pressure wave interaction signal for those measurement locations located on the other side of the generation location compared to the reference measurement location, the positive shift corresponding to the time interval that the pressure wave takes to travel from the generation location to the respective oppositely located measurement location; applying no time shift to the respective pressure wave interaction signal for those measurement locations located at the generation location; and identifying common features in the time shifted pressure wave interaction signals, the common features corresponding to a subset of localised variations located on the other side of the generation location compared to the reference measurement location.
