Doc. 234/20Internal Inspection of Decommissioned Flat Bottom Tanks

This publication aims to give recommendations for inspections of decommissioned cryogenic flat bottom tanks. It also aims to build a library of inspections available to EIGA members that will demonstrate the absence of aging mechanisms in this type of equipment and allow continued operation of the equipment without periodic internal inspection.

This publication provides guidance for inspections when a cryogenic flat bottom tank is decommissioned. However, in some exceptional cases, an internal inspection can be required, for example after an overfill or overpressure incident, tank contamination, or after repairs / refurbishment.
