Abstract: IN THE LATE 1970s, surveying buried pipelines from the surface without excavation was a black art. Depending on the circumstances, an experienced engineer might be able to locate a proportion of the faults in the coating but, inevitably, an unknown number would be missed which could, in time, lead to corrosion and possible pipeline failure. At that time we had discussions with a major UK operator of cross-country gas transmission pipelines who asked us to look for a fundamentally-new approach to the problem. We needed technology that would be accurate, consistent, comprehensive, repeatable, and economical in both time and labour.
