CML Optimization Services

Smarter Condition Monitoring Locations (CMLs) to improve inspection coverage, reduce costs, and strengthen piping integrity programs.

Optimizing CMLs for Better Piping Integrity Decisions

Our CML Optimization Services help facilities redesign and refine their Condition Monitoring Locations so inspections focus on the right points, at the right frequency, with the right data density.

CML Review & Rationalization

We assess your current CML program to identify:

  • Redundant or low-value CMLs

  • Gaps in high-risk areas

  • Inconsistent CML spacing and placement

  • Over-inspected and under-inspected circuits

Image

Corrosion Loop & Circuit Optimization

We align CMLs with:

  • Corrosion loops

  • Piping circuits

  • Expected damage mechanisms

  • Operating conditions (temperature, pressure, fluid)

This ensures CMLs are placed where degradation is most likely to occur.

Image

Risk-Based CML Placement

We prioritize CML locations using:

  • Probability of Failure (PoF)

  • Consequence of Failure (CoF)

  • RBI outputs (API 580/581)

  • Known corrosion “hot spots”

This approach focuses inspection effort on piping that truly drives risk.

Image

CML Type & Technique Selection

We recommend which techniques best fit each CML:

  • Manual UT

  • Automated UT (AUT)

  • Corrosion mapping

  • Radiography (RT) in specific locations

  • Profile RT or PAUT in localized thinning

 

Image

CML Count Optimization

We find the balance between:

  • Enough data to make safe decisions

  • Not so many CMLs that the program becomes unmanageable

Result: better coverage with fewer, better-chosen CMLs.

Image

Implementation & Data Management Support

We provide:

  • Updated CML lists and maps

  • Recommendations for tagging / labeling

  • Guidance for integrating with inspection software / CMMS

  • Input for RBI and inspection planning tools

Our CML Optimization Workflow

Image

Step 1 — Data & Program Review

We review:

  • Existing CML lists

  • Circuitization and corrosion loops

  • Past UT data and corrosion trends

  • RBI outputs (if available)

  • P&IDs, isometrics, and line lists

Image

Step 2 — Engineering & Risk Evaluation

We evaluate damage mechanisms, operating conditions, and piping design to identify critical locations.

 

Image

Step 3 — Optimized CML Layout

We propose a revised CML strategy:

  • Added CMLs where risk is high

  • Removed or consolidated CMLs where value is low

  • Adjusted spacing and distribution along circuits

Image

Step 4 — Implementation Support

We deliver updated CML tables, maps, and guidance for integrating the new program into your inspection management system.

 

Image

Step 5 — Continuous Improvement

We can support periodic reviews as new inspection or operating data becomes available.
