A method to further enhance the gains of RBI and create greater distinction between the inspection regimes for negligible risk and higher risk levels is Compliance-based integrity assurance or CBI. CBI will:
Use the functional specifications and performance standards for the robustness of pressure containing equipment.
Determine the operating windows that assure compliance with the performance standards.
Determine and design the verification and monitoring system that delivers integrity assurance.
In this way, CBI can result in a significant reduction of inspection resources that would typically be required when only RBI is applied. In the oil &gas and the process industries the benefits can be substantial.
