An owner-operator wishes to establish minimum required thickness limits for thickness monitoring locations (TML) or condition monitoring locations (CML) because current minimum measured thickness values reflect loss in excess of the original design corrosion allowance for the component.

If the project involves multiple equipment items, develop a project technical protocol document to establish the technicalasis for the project and to ensure consistency with the assumptions, methodologies, and deliverables. Perform required thickness calculations for eachcomponent using the applicable Code of Construction. Leverage Fitness-For-Service (FFS) technology to justify less conservative thickness limits for various components and/oroations using the various methods outlined in API 579-1/ASME FFS-1 Part 2 andPart 4.
