Abstract: Methods of processing a data signal obtained from a sensor sensing a dynamic signal to detect a structural anomaly event are disclosed. In one embodiment, a method includes obtaining signal components attributable to fluid flow at a location within an operational pipeline network; processing the data signal to extract one or more features; characterising the one or more extracted features; and detecting an indication of a structural anomaly event proximal the location depending on the characterisation; wherein the structural anomaly event includes an occurrence and/or further development of a structural anomaly.

Abstract: A method for detecting a structural anomaly in a pipeline supply network is disclosed where the pipeline supply network is configured to supply fluid to multiple receiving locations. The method comprises receiving acoustic signal data from a selected location in the pipeline supply network and generating a first time window of acoustic signal data based on the acoustic signal data. The method then includes benchmarking the first time window of acoustic signal data with respect to historical background acoustic signal data characterising the pipeline supply network to generate a corresponding background benchmarked first time window of acoustic signal data and then determining an anomaly measure for the background benchmarked first time window of acoustic signal data where the anomaly measure indicates a presence of the structural anomaly.

Abstract: A system for generating a pressure signal in a pipeline system containing a pressurised fluid is disclosed The system includes a discharge valve in fluid communication with the pressurised fluid of the pipeline system to allow fluid from the pipeline system to discharge and an electronic controller to dynamically control a degree of opening of the discharge valve to selectively vary the discharge valve between a plurality of valve opening states to generate the pressure signal in the pipeline.

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 pressure wave generating location along the pipeline system and detecting pressure wave interaction signals at two closely spaced measurement locations along the pipeline. The method then includes determining a system response function for the pipeline based on the detected pressure wave interaction signals for each measurement location and characterising the pipeline based on the system response function.

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.
