Leak noise characterisation for buried, fluid-filled pipes.

Lead Research Organisation: University of Southampton
Department Name: Faculty of Engineering & the Environment

Abstract

Leakage from pipes is a major issue in both the water and oil industries, being an issue, not only in environmental terms, because of wasting important natural resources, but also in economic and health terms, from both an environmental and cost perspective. Acoustic methods predominate in the armoury of available leak detection methods. However, their effectiveness can be limited by a number of factors, not least of which is the lack of knowledge of the acoustic characteristics of leaks.
Little work on this topic is available in the literature. Some preliminary work has been undertaken at the ISVR which has identified some of the potential mechanisms for leak noise, along with the key parameters on which the noise might depend. However, the effect of the surrounding soil was not included in this work, in which the experiments were conducted on a pipe rig in the laboratory.
The aim of this project is to further the initial work described above through numerical simulations and experiments, both in the laboratory and in the field. Of particular interest is
The differences in leak noise signatures between metal and plastic pipes
The effect of leak shape/size, taking into account the different modes of failure normally encountered in metal/plastic pipes
The effects of the surrounding soil
