- Risk-based inspection (RBI) is an optimal maintenance business process used to examine equipment such as pressure vessels, quick-opening closure - doors, heat exchangers, and piping in industrial plants. RBI is a decision-making methodology for optimizing inspection plans. The RBI concept lies in that the risk of failure can be assessed in relation to a level that is acceptable, and inspection and repair used to ensure that the level of risk is below that acceptance limit.
- RBI is part of risk and reliability management. The basis of most RBI programs is the corrosion circuit, in which each circuit can be compared for relative risk levels to aid in inspection and maintenance planning.
