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 27):
A method for assessing the condition of a section of pipeline in a pipeline system, the method comprising:\n generating a first pressure wave in the fluid being carried along the pipeline system, the first pressure wave generated at a location upstream or downstream of the section of pipeline; detecting a first pressure wave response signal at a first set of one or more measurement locations along the pipeline system; generating a second pressure wave in the fluid carried along the pipeline system, the second pressure wave generated at a location downstream of the section of pipeline if the first pressure wave was generated upstream or alternatively at a location upstream of the section of pipeline if the first pressure wave was generated downstream; detecting a second pressure wave response signal at a second set of one or more measurement locations along the pipeline; comparing by time-shifting the first and second pressure wave response signals measured at the first and second set of measurement locations to identify the source locations and directions of pressure wave reflections measured in the first and second pressure wave response signals; dividing the section of pipeline into a two or more sub-sections according to a selection of the source locations of the pressure wave reflections; and assessing the condition of each sub-section of the section of pipeline based on a localised characterisation of each sub-section of the section of pipeline.
