Evaluation of hydro acoustic condition monitoring of subsea processing equipment
MetadataShow full item record
The project described in this thesis is based on the perceived fact that a need for advancements in monitoring technology results from the development of more complex subsea equipment. An existing type of hydro acoustic leak and vibration detection technology will be tested with the aim of extending its function from leak detection to an application as condition monitoring. This will be done in conjunction with the testing and commissioning of the Ormen Lange Subsea Compression Pilot. An evaluation of the benefits from such testing has been performed based on information and understanding gained through project planning, and through investigation into the function of equipment and physics involved. The overall conclusion of this evaluation is that the extended function testing of the ALVD (Acoustic Leak and Vibration Detection) monitoring unit, will result in improved knowledge regardless of the test results. The improved knowledge can possibly be used for improving the existing function towards higher sensitivity and level of detail. The potential of developing a multifunctional monitoring system capable of both leakage detection and condition monitoring of several components simultaneously is interesting and deserves to be explored.
