  • Underwater pipelines
    Patent number: 3992924
    Abstract: A leak in an underwater liquid filled pipeline is located by moving a receiver capable of detecting ultrasonic energy of frequency in the range 20 to 70 kilohertz along a path parallel to the axis of the pipeline at a distance of 100 to 2000 feet from the axis of the pipeline measured in a horizontal plane. The receiver noise generated by liquid escaping from a leak is detected with the receiver.
