About Corrosion Analysis Settings

Corrosion Analysis Settings let you specify certain options that control how various values will be calculated in Asset and TML Corrosion Analyses. While Corrosion Analysis Settings exist as records, the settings should only be accessed and modified via Thickness Monitoring. Corrosion Analysis Settings are used to calculate fields in Asset Corrosion Analyses. They are also used to populate fields in TMLs, and to determine values in the linked TML Corrosion Analyses. Some values can be defined at the asset or TML Group level, and then customized at the TML level. You will need to configure the Corrosion Analysis Settings based on the requirements of your organization. This will ensure that the analyses yield results that are useful and are meaningful to you and your organization. You can also select any that you defined via the TM Admin Preferences page.

For Assets and TML Groups

In a Corrosion Analysis that includes both an asset and TML Groups, Corrosion Analysis Settings must be defined for the asset and each TML Group. If you access an asset or TML Group in Thickness Monitoring that does not have Corrosion Analysis Settings defined, the Corrosion Analysis Settings workspace will be displayed automatically.

Different settings can be defined for each Inspection Type (UT, RT, and TML). When you create the Corrosion Analysis Settings for an asset or TML Group, you will need to choose the Inspection Type for which you want to configure settings. The Corrosion Analysis Settings that you create at the asset level can then be spread to the TML Group level (i.e., Corrosion Analysis Setting can be created and linked automatically to the TML Group) in the following scenarios:

When you create a new TML Group for asset.
When you define Corrosion Analysis Settings of a new Inspection Type for an asset. You can specify which existing TML Groups receive the new settings through the Select Spreading window.

The Corrosion Analysis Settings for a TML Group can also be accessed and modified individually.

IMPORTANT: Analysis settings must be defined for asset and TML Group before you begin creating TMLs of a given TML Analysis Type and linking them to TML Groups.

For TMLs

On the TML level, the Corrosion Analysis Settings control how various values will be calculated in the TML Corrosion Analysis that is linked to a TML.

When you create a TML, Corrosion Analysis Settings are created and linked to it automatically. The Corrosion Analysis Settings for a TML are created using the settings defined for the asset or TML Group to which the TML is linked.

Most Corrosion Analysis Settings are defined at the asset or TML Group level. The following settings can be defined at the TML level:

Allowable Measurement Variance
Corrosion Rate Variance
Default Inspection Interval
Minimum Corrosion Rate
Std Deviation Factor

After Corrosion Analysis Setting exist for a TML, you can modify the TML-specific settings via the Corrosion Analysis Settings workspace.
