Deployment

The baseline GE Digital APM database includes the Thickness Measurement Location family, which contains the TML Analysis Type field. This field is used to classify TMLs based upon the collection method that will be used for recording Thickness Measurements at that location.

The TML Analysis Type field contains a list of values that is populated with the Corrosion Inspection Type values from all Corrosion Analysis Settings records that are associated with the asset or TML Group to which the Thickness Measurement Location record is linked.

The values that are used to populate the Corrosion Inspection Type field in the Corrosion Analysis Settings family are stored in the System Code Table CITP (Corrosion Inspection Type). In the baseline GE Digital APM database, this table contains three System Codes: UT, RT, and TML. You can only create Thickness Measurement Location records with a given TML Analysis Type value if an associated Corrosion Analysis Settings record contains the same value in the Corrosion Inspection Type field.

Using the baseline functionality, you can separate Corrosion Analysis calculations into groups based upon TML Analysis Type. If you want to use this functionality, you will want to classify your TMLs as UT (measurements collected using ultrasonic thickness) or RT (measurements collected using radiographic thickness). This separation will be desirable for some implementations. Other implementations will prefer not to separate TMLs according to collection method and instead perform calculations on the entire group of TMLs that exists for an asset. For these implementations, you will want to classify all TMLs using the TML Analysis Type TML.

Depending upon your preferred implementation, you may choose to make one or more of the following changes to the System Code Table CITP (Corrosion Inspection Type):

• Add System Codes if you want to classify TMLs using methods in addition to UT and RT.
• Delete System Codes that you do not want to use.
• Modify the IDs and descriptions of the System Codes so that the classification options are more intuitive to your users.

If you make changes to this System Code Table, keep in mind that the analysis types that are stored in the System Code Table CITP (Corrosion Inspection Type) will be used when you create Corrosion Analysis Settings records, and therefore, will determine the analysis types for which you can create Thickness Measurement Location records.

Additionally, in Thickness Measurement Location records, the TML Analysis Type field has a baseline Default Value rule that is coded to present UT as the default value when you have defined the UT TML Analysis Type in your Corrosion Analysis (i.e., you have created a Corrosion Analysis Settings record with a Corrosion Inspection Type of UT). You could modify this rule if, for example, you wanted RT to be presented as the default value when you have defined the RT TML Analysis Type in your Corrosion Analysis (i.e., you have created a Corrosion Analysis Settings record with a Corrosion Inspection Type of RT). To do this, you would modify the MI_TML_TYPE_CHR class as follows:

            <MetadataField("MI_TML_TYPE_CHR")>  _
            Public Class MI_TML_TYPE_CHR
                Inherits Baseline.MI_Thickness_Measurement_Location.MI_TML_TYPE_CHR
                Public Sub New(ByVal record As Meridium.Core.DataManager.DataRecord, ByVal field As Meridium.Core.DataManager.DataField)
                    MyBase.New(record, field)
                End Sub
                Public Overrides Function GetDefaultInitialValue() As Object
                    Return CStr("RT")
                End Function
            End Class
