LEAK DETECTION IN UNDERWATER OIL PIPELINES

The findings of a brief state-of-the-art review of leak detection devices suitable for underwater oil pipelines is discussed. The review includes consideration of leak or crack detection by flow measurement, pressure, ultrasonics, acoustic emission, magnetic flux, visual examination, eddy current, radioactive slugs, electromechanical and electrochemical tapes, doublewalled pipes, coaxial cable, lasers, permeable membranes, and remote sensing. The review was performed to provide appropriate pollution control information prior to the construction of underwater oil pipelines from deep water tanker terminals to shore facilities. It was recommended that a stationary ultrasonic through-the-pipe-wall crack/flow detector be used with a coaxial cable and shroud positioned a short distance above the pipe.
