Abstract

A method of detecting leakage passing along a leakage path extending from a known external leakage point through an internal lining of a fluid storage tank, said method comprising: applying a pressure differential between an inner surface of said lining and an outer surface of said storage tank; moving acoustic transducing means over said external surface; and detecting, with said acoustic transducing means, acoustic signals characteristic of said leakage path during said movement to identify the course of said leakage path.
