MiRO CMLs

You always need to define CMLs for your Circuit. This is where the Measurements will take place, at the Measurement Points (MPs).

Creating CMLs

Go to the Circuit Details Page.
Scroll down to the CML tab.
Click the Plus button.

Enter the required data in the pop-up window. See the table below.
Click Save when done.

The new Circuit will be created, and you will be redirected to the Detail Page of the CML that was just created.

Note

Your content goes hereYou can open a CML Details Page at any time by clicking on the hyperlink in the CML column on the CML tab in the Circuit Details Page.

CML pop-up (pay specific attention to the field indicated in bold):

Field	Description
Circuit	The Circuit ID. This should already be selected.
Sub Circuit	Sub-Group of the selected Circuit, for grouping similar CMLs within a Sub-Circuit. The Sub-Circuit-CML combination should be unique. If you do not want to group CMLs you can use this as a short description. It is a mandatory field.
CML	The CML ID. This will become a hyperlink in the CML grid that you can click to open the CML Details Page.
CML Type	Type of CML (e.g., PIPE, HEADER BOX, REDUCER, TEE, SHELL, CHANNEL, NOZZLE).
CML Description	This can be used for an optional description (in addition to the Sub Circuit).
Must Get	Check if this CML must always be measured.
Position	Position of the CML in the Circuit.
MP Configuration	For MiRO Pipes, select the "Pipe - 6 x 1" configuration.
Active	By default the CML should be Active.
Piping Class	Applicable to Pipes. Select the Piping Class to set other parameters on the CML.
Material	Select from predefined list.
Nominal Diameter	Select a predefined Diameter.
Nominal WT	Nominal Wall Thickness for the CML.
Actual OD	Actual Outside Diameter
Renewal Thickness	Minimum Wall Thickness (WT) for the selected CML.
Renewal Basis	Renewal basis, either CALCULATED, FITNESS FOR SERVICE, NOMINAL MINUS CORR ALLOWANCE, STRUCTURAL MIN.
Required Inspection Method	Option to set a required Inspection Method (e.g. UT, RT) for all measurement for the CML (optional). Use UT-R for datalogger import and UR for the DIMATE-PACS interface.
Design Corrosion Allowance	Mandatory.
Drawing Filename	Search for and add a related drawing.
Line number on drawing	Line number on drawing
Line number in P&ID	Line number in P&ID
Sketch number	Sketch number
Longitude	Longitude
Latitude	Latitude
Altitude	Altitude

Assigning a Piping Class to a CML

When a CML is created you can assign a Piping Class to it.

The Piping Class sets:

Material
Available Nominal Diameters to select from

Then the selected Nominal Diameter – sets:

Nominal WT
Renewal Thickness (from Over. Renewal WT as defined in the Piping Class)
Actual OD (from Diameter as defined in the Piping Class)
Design CA (Corrosion Allowance)

This data comes from the Piping Classes that are defined in Settings.

Calculating Minimum Wall Thickness(TMIN)

The CML Details page allows you to calculate the Minimum Wall Thickness using the TMIN Calculators. These calculators are based on recognized industry standards, specifically ASME Section VIII (Vessels, Heat Exchangers) and ASME B31.3 (Process Piping). See Calculating Renewal Thickness with TMIN Calculator.

The CML Tab

The CML section provides a list of CMLs for the selected Circuit. The CML tab shows an overview of the CMLs. The CML grid columns are explained here.

The CML section is used to create and maintain the applicable CMLs for the selected Circuit. The grid shows a toolbar which can be used to do so.

CML toolbar:

Icon	Action	Description
	Edit or Cancel and Save	Edit or if in Edit mode the Cancel and Save buttons show. Save changes you made in the editable grid (such as Renewal Thickness, Renewal Basis or Nominal WT).
	New and Delete	Create a new CML, which opens a new screen in which CML data for the new CML should be populated. Or Delete an Existing CML.
	Export	Export the list of CMLs to a Microsoft Excel file.
	Copy	Copy a selected CML.
	Paste	Paste the copied CML as a new CML, measurements are not copied.
	Move	Move (copy) CMLs to another Circuit. This way you can also move (copy) old wall thickness measurements to a "new Equipment". A recalculation will happen at both the origin and destination Circuit.
	Select New Predefined MP	Opens the registered MPs for the CML and allows you to directly add other Measurement Point(s).
	Show only selected	Check to show only the selected rows.

The CML Measurement History Tab

The CML Measurement History tab shows the list of Wall Thickness (WT) Measurements per actual Measurement Point (MP), performed in each Measurement Set (MSET) – Measurement date.

CML Measurement History grid:

Column	Description
Active	Indicator whether the CML is active or inactive.
Sub Circuit	Sub-Group of the selected Circuit, for grouping similar CMLs within a Sub-Circuit. The Sub-Circuit-CML combination should be unique. If you do not want to group CMLs you can use this as a short description. It is a mandatory field.
CML	CML, click to open CML details.
Description	Short description of the CML.
Nominal Diameter	Nominal Diameter.
Actual OD	Actual Outside Diameter.
NWT	Nominal Wall Thickness.
RWT	Renewal Wall Thickness - Minimum Wall Thickness for the selected CML
RCA	Remaining Corrosion Allowance
RL	Remnant Life date
NID	Next Inspection Date
AMP	Actual Measurement Point

CML Measurement History toolbar:

Icon	Action	Description
	Edit or Cancel and Save	Edit or if in Edit mode the Cancel and Save buttons show. Save changes you made in the editable grid (such as Renewal Thickness, Renewal Basis or Nominal WT).
	New	Create a new CML, which opens a new screen in which CML data for the new CML should be populated. Or Delete an Existing CML.
	Export	Export the list of CMLs to a Microsoft Excel file.
	Move	Move (copy) CML to another Circuit. This way you can also move (copy) old wall thickness measurements to a "new Equipment". A recalculation will happen at both the origin and destination Circuit.
	Select New Predefined MP	Opens the registered MPs for the CML and allows you to directly add other Measurement Point(s).
	Legend	Click to show the legend. For more information also see MiRO Reviewing Errors and Warning (CML History tab).
	Condense dates	When you have many CMLs, use this option to make one column per year.

You can use the filter to find specific CMLs. For example filter for CMLs with Warnings and Errors. For more information on the Measurement quality see MiRO Reviewing Errors and Warning (CML History tab).

The filter can be used to find Warnings and Errors.

See the PEI CMLs Details page for more information.
