Acoustic emission of offshore structures, attenuation - noise - crack monitoring
No NDT crack detection methods have up to now proved to be the method which can overrule the others. We shall probably in the future in the offshore industry see a combination of various structure monitoring systems, remotely operated vehicles (ROV) with NDT-equipment and also the use of divers. The author believes that in some 5 - 10 years ROVs will perform much of the routine inspection, and mobile monitoring instrumentation will be concentrated to some hot spot areas, already detected defects or any repairs. The main areas for AE are monitoring of pressure vessels and fibre reinforced plastics. For application on offshore structures some fullscale trials have been performed (with practical problems) as well as some laboratory studies. Norwegian institutions seem to have a leading role today in the research of offshore applications. Norsk Hydro participated in a signature analysis project at Sintef/Veritas some years ago.
