IMCA Publishes Information Note on NDE Testing of Gas CylindersThe International Marine Contractors Association (IMCA), London, United Kingdom
The International Marine Contractors Association (IMCA) has published an information note on non-destructive evaluation (NDE) testing of gas cylinders.
Advancements in NDE testing techniques for gas cylinders have been the subject of extensive discussion by members of the IMCA Diving Division Safety, Medical, Technical & Training Committee (SMTT). A dedicated workgroup of industry experts was established to take the issue forward and to develop an update of detail sheet 9.1 of IMCA D 018 ? Code of practice on the initial and periodic examination, testing and certification of diving plant and equipment. The updated detail sheet 9.1 of IMCA D 018 will be included in the next revision of IMCA D 018. The information note (IMCA D 08/11) is available to IMCA members on the ?members-only? website.
The detail sheet sets out additional guidance for the possible use of ultrasonic NDE testing techniques in place of a five yearly internal examination and overpressure test, provided that certain key prerequisites have been met. Internal moisture levels are a key factor to consider when using such testing techniques and, as such, NDE testing of cylinders used for compressed air storage would not be appropriate.
The information note stresses six key points:
