AUV & PIG Inspections

AUV Inspection The technique is similar to the ROV except that the system is mounted in a fixed position at the front of the AUV and the data are recorded for later playback. PIG Inspection For situations where the pipeline is deeply buried in seabed sediments or for pipe-in-pipe, leak detection can be conducted by mounting a recording acoustic leak detection system on a pipeline PIG. As the PIG passes through the pipeline it will detect a leak due to the ultra-sound generated by the leak and by noting the point of largest signal the location of the leak is determined. It is necessary for the PIG operating contractor to provide a means of tracking its passage through the pipe in real time so that time tagged leak data can be related to location after the data are downloaded.
