Guidelines for CO2 Corrosion Model Validation / VerificationCommercial CO2 model software developers typically do not provide users with any validation or verification details. Validation or verification of modeled results against lab or field data is often difficult as quality lab or field data under the prevailing operating conditions used in the CO2 corrosion prediction software are not readily available. This is particularly true at the design stage where the input parameters are often simulated or projected. Verification of modeled results against corrosion monitoring data in the field may not be applicable as the corrosion monitoring data is "spot" measurement at a specific location under some uncertain local operating conditions while the modeled results represent the "worst case" scenario in the whole system (not spot measurement) under the specific operating conditions. The only practical way to make sure that your modeled results are reasonably reliable is to verify the CO2 corrosion modeling software itself by using your own or any 3rd party's well-defined quality lab and/or field data before starting the modeling project. It is critical to use your own or any 3rd party's quality data, not the model developer's data (JIP or in-house), for the verification process. Any use of poor quality data would defeat the whole purpose of verification. WebCorr has developed a CO2 Corrosion Model Validation Matrix and Index Score system for objectively and quantitatively determine a CO2 corrosion model's accuracy of prediction.
