Abstract

A method for determining the location of underwater pipeline leaks comprising first measuring the resulting pressure within the pipeline, calculating depth of pipeline at the site of the leak and then determining the location of the leak by reference to a graph of the profile of the pipeline which plots the depth of the pipeline against the distance of the pipeline from shore.
