1. A method for implementing a hierarchical Bayesian model for pipe wall thickness monitoring, comprising automating construction of the model nodes for a particular equipment, utilizing component data, historical thickness measurements and related inspection information and;
where the hierarchical Bayesian model utilizes an overarching corrosion rate distribution and hierarchal shrinkage to account for the potential for differences in condition monitoring location (CML) rates.
