PEI EVA

This online manual explains: The EVA (Extreme Value Analysis) methodology in IMS. Methodology Overview EVA (Extreme Value Analysis) is a statistical method to calculate the maximum Wall Loss, from a smaller representative sample, e.g. for...

Preparation for doing an EVA. Some preparation is needed before you can start an EVA (Extreme Value Analysis). When the hierarchy (Equipment, Circuit, CMLs and MSs) is set up, the inspection data must be inputted into the MSs, and then t...

Doing the EVA. You are ready to start the Extreme Value Analysis when: EVA is activated; The CMLs have measurements; The Nominal WT  and Renewal thickness are filled in for all the CMLs with measurements; and The Equipment has...

Doing the EVA. When the EVA calculation is done, it is time to review the results. The purpose of the Goodness of the Fit tests is to investigate how well a given sample of data approximates a given probably distribution. Failing t...

Implementing EVA results. Lastly, after you did the EVA , you need to close the loop by calculating the NID for the Corrosion Schedule … Approve the Calculation Summary The Calculation Summary summarizes the different methods (e....
