Condition Monitoring Locations (CMLs)

What are Condition Monitoring Locations (CMLs)?

CMLs are designated points on assets (pipelines, pressure vessels, or other critical assets) where thickness measurements are taken over time to monitor corrosion, erosion, or other degradations. They help to assess equipment health and drive predictive maintenance strategies.

What is the purpose of CML management?

To monitor asset condition through critical parameters e.g., Tmin (Thickness Minimum) & MAWP (Maximum Allowable Working Pressure) enabling proactive maintenance and extending asset life.

How does CML trending work?

The trending feature allows you to graph and track historical data of CMLs and assess the remaining life of assets. By visualizing data over time, you can identify patterns and trends in corrosion or wear, allowing for early issue detection and more accurate predictions of asset longevity.

How do CMLs contribute to predictive maintenance?

By analyzing thickness trends at CMLs, user can predict when repairs will be needed, reducing unplanned downtime and improving reliability. This predictive approach helps reduce downtime and avoid costly emergency repairs, making maintenance efforts more efficient.

How do I create a CML?

You can create a CML within the AsInt platform by designating specific regions on your assets, such as pipelines or pressure vessels. During creation, you can set parameters like the Thickness Minimum and Maximum Allowable Working Pressure (MAWP) to ensure that the asset operates within safe limits.

Can I access historical CML data for analysis?

Yes, the trending feature allows you to access and analyze historical CML data. This includes tracking corrosion rates, damage progression, and the remaining life of assets. With this data, you can make data-driven decisions and improve asset management strategies.

Is it possible to use the CML module without RBI, just by adding a Tmin and organizing the WT measurements to get the remaining life?

Yes, you can manage multiple CMLs across different assets. Whether you’re monitoring pipelines, pressure vessels, or other equipment, you can set up and track CMLs specific to each asset, providing a comprehensive view of their health and performance over time.

Can I monitor multiple CMLs across various assets?

Yes, you can manage and trend multiple CMLs across different equipment for a complete asset health overview.

What are Tmin and MAWP?

Thickness Minimum (Tmin): The minimum wall thickness required to maintain asset integrity.
MAWP (Maximum Allowable Working Pressure): The highest pressure an asset can safely handle, calculated based on the Tmin and design criteria.

How frequently should I check the Condition Monitoring Locations (CMLs)?

The frequency of inspections will depend on the asset’s usage, environment, and risk factors. Typically, regular monitoring should occur based on the asset’s criticality and the rate of corrosion or damage observed in past readings. You can set reminders or schedules for inspections within the app to ensure timely checks.

How does the module help with CML optimization?

It allows you to:

  • Track corrosion rates
  • Reassign or consolidate redundant CMLs
  • Manage anomalies proactively based on measured data

Why is CML selection important?

Accurate CML selection ensures:

  • Targeted inspection coverage
  • Early detection of corrosion
  • Data-driven integrity assessments

Is it possible to use CMLs without RBI?

Absolutely. You can set Tmin and track thickness measurements independently of RBI to monitor asset life and make maintenance decisions.
