There are many facets to a “good” Mechanical Integrity (MI) program, with accurate and up-to-date data being the most critical. With a plethora of data points, it can be difficult to know what good data is and how you can utilize it to improve your program. By organizing and continuously updating your data, you can ensure that your MI data supports better decision making. Use the checklist below to see where your MI program might be missing the mark and what you should incorporate into your program to achieve best in class:

How Good Is MyMechanical Integrity Data?

MI Asset List

There is documentation of all assets in the program and all these assets are represented on the P&IDs, in the Inspection Data Management System (IDMS), and the Computerized Maintenance Management System (CMMS).

Piping Circuits and Specifications

All piping on the P&IDs is circuitized and includes up-to-date piping specifications. Each of the circuits are represented in the IDMS and has an associated functional location in the CMMS.

Heat and Material Balances

If a damage model is to be built, ensure there are accurate Heat and Material Balances with associated contaminant levels to reference.

Condition Monitoring Locations

All Condition Monitoring Locations (CMLs) are logged in the IDMS and align with the inspection drawings.

Risk Based Inspection (RBI)

If RBI is being utilized, ensure all required data for both Probability of Failure (POF) and Consequence of Failure (COF) are accurate and up-to-date.  These fields can vary depending on the risk-based philosophy employed.

MI Documentation

All key MI documentation, including: U’s, R’s, construction drawings, and past inspections are controlled in a single location and organized by asset. The documentation can be hardcopy or digitized.


The IDMS is well-implemented and is a trusted and reliable source of information including design data, historical inspections and planned inspections.

Damage Model

If a damage/corrosion model has been developed, it should be continuously updated to include process and design changes and used to drive inspection strategies housed in IDMS.

Management of Change (MOC)

All MOCs in the past 6 months have been processed with mechanical integrity in mind and any key updates have been incorporated into the asset strategies and IDMS.

Thickness Data

Ultrasonic Thickness (UT) growths are less than 5% of total UTs in the past year, and at least two rounds of UT readings on assets for build short/long term rates.
