Risk-Based Inspection (RBI)
PCMS provides a fully integrated RBI module within the program. Design, operating, and inspection data from PCMS continually feed the RBI calculator, providing a true evergreen approach to RBI management. The user has the choice in PCMS to a Semi-Quantitative (API 580/581), Qualitative, or Imported (3rd party) RBI approach.
Semi-Quantitative RBI
The PCMS Semi-Quantitative RBI Calculator has been developed by using base models and theory from API 580, 581, RIMAP Petrochemicals, Tischuk T-OCA, as well as PCMS RBI Subcommittee enhancements.
Features and benefits of the PCMS Semi-Quantitative RBI Calculator include:
- Maintain inspection data and perform RBI analysis all within one software program.
- Supports API 580/581 guidelines with input from industry experts and PCMS user group subcommittee enhancements.
- Fully embedded inside PCMS to promote a true "evergreen" implementation.
- Automatically identify susceptible damage mechanisms and consequences per circuit.
- Automatically creates inspection plans identifying potential damage mechanisms & recommended inspection techniques & effectiveness.
- Generates RBI target dates based upon risk thresholds to aid the inspection planning process.
- Performs 'What If' analysis based on inspection effectiveness applied.
- Customizable risk matrix dimensions & parameters.
Qualitative RBI
PCMS also offers a Qualitative RBI approach for clients who prefer this form of RBI methodology. Damage mechanisms, consequences, and overall risk rank can be assigned to each equipment or corrosion circuit in the program. Damage mechanism inspection intervals as well as inspection procedures and techniques can be configured per risk rank and used in inspection scheduling analysis as well as the inspection execution. Updates to any damage mechanism in the program will seamlessly update any future inspection schedule.
Imported RBI
If the user prefers to perform RBI analysis outside of PCMS (3rd Party RBI Tool), PCMS can integrate these results directly in the program through use of the RBI Integrator. Users can also export any PCMS data needed to perform RBI outside of the program (design, operating, inspection grades, corrosion rates, etc.). The RBI Integrator will allow the user to perform proper RBI analysis using actual inspection data maintained in PCMS, while providing a central platform to continue to schedule, record, and analyze asset integrity from within one application.
