Damage done to petroleum pipelines can be catastrophic if left undetected with time. Most of these damages results in financial losses, environmental pollution and frequent loss of life as a result of explosion due to prolong exposure of pipeline products. Therefore, damage detection and location techniques will play a key role in the overall integrity management of a pipeline system. This paper addresses the development and testing of mathematical techniques for locating an impulsive event on a pipeline and reconstructing the pressure pulse caused by it from measurements made remotely. When an impulsive event occurs along a pipeline, the pressure pulse propagates in both directions and can be detected and measured by sensors located at different positions along the pipeline. From these measurements the location of the event can be determined and its form reconstructed. Techniques for reconstructing the pulse at it source from the distorted pulses measured were developed using deconvolution theory and inverse methods. This theoretical work was validated by experiments using a simulated pipeline. The experimental work was carried out using a test rig comprising a flexible hose pipe 23 m long and 19 mm diameter with four pressure sensors distributed along the pipe and connected to a data acquisition system. The techniques were tested for static and flowing air in the pipe, and were found to give good results.
