Within the evolution of inspection programs, fixed interval inspection regimens were replaced by condition-based monitoring approach, where calculations were made for corrosion rates and thoughts were given to damage progression and damage mechanisms. Condition based monitoring was better in comparison to the time-based approach, but consequence of failure was not yet factored into the decision making process. Condition based monitoring was then followed by Risk Based Inspection (RBI), where inspection programs are defined on a risk basis considering damage mechanisms, probability of failure and related consequence.
NIMA RBI approach was developed based on the guidance given in API Recommended Practices 580/581, focusing on the generation of inspection programs that improve operator knowledge about the damage state of their equipment, reducing the uncertainties and clearly defining the level of risk.
NIMA Tanks RBI provides the basis for intelligent decision making on inspection frequencies, the extent of inspection, and the most suitable type of Non Destructive Testing applicable to Atmospheric Storage Tanks (AST).
