ABSTRACT:
Method and apparatus for detecting the location of a marine pipeline or cable, whereby acoustic pulses are transmitted by a submarine pulse transmitter carried by a vessel. These pulses, as well as the reflections of the pulses on the seabottom and on the pipeline or cable are detected by means of two detectors that are carried by two paravanes towed by the vessel. The signals received by the detectors are combined and the record of the combined signals is displayed. The signal parts that are representative of the acoustic waves reflected by the pipeline are identified in the record by separate colors or various intensities of a single color.
