Take note

This overview will explain how to interpret the IMS-PLSS Systems Details Page.

To open a Systems Details Page, click on the desired System ID hyperlink in the System Main Screen (or any other screen). See IMS Details Page.

The Systems Details Page can be divided into sections:

Header

The header of the Detail page shows the name of the name of the System / System ID and several navigation options.

For more information on the icons see IMS Details Page.

The sections, listed in blue, are common to all Equipment Groups. For more information on these see PLSS Equipment, as well as IMS Details Page. Below we explain the sections specifically applying to Systems, i.e., Equipment with Equipment Group "PLSS System".

Equipment

In the Equipment section, all the Equipment that are part of this PLSS System should be selected.

Adding Equipment

To add Equipment to the System:

Click the Plus button.
Click the plus button.
An overview of all Equipment will be shown.
Select all the Equipment that should be added to the PLSS System.
Select all the Equipment that is part of this System.
Click OK.

The selected Equipment will be shown in the Equipment grid.

Equipment grid with the selected Equipment.

Degradation Management

In the Degradation Management section, the Degradation Mechanisms (DMs) and Barriers are defined.

This section allows you to select a view between a Board or Grid View. The Board view, allows you to add Degradation Mechanisms and Barriers.

To switch between the Views:

Navigate to the Degradation Management section.
Click on the down-arrow on the top-right of the section.
from the drop-down menu select Board or Grid.

A Degradation Mechanism can have multiple Barriers (primary, and secondary). Multiple Indicators help determine the Barrier Status, i.e., Inspection Findings, Corrosion Calculation, IOW, Samples etc.

The Indicator Status can be:

Red – Barrier not effective.
Amber – Barrier effectiveness impaired.
Yellow – Barrier not (fully) effective and plan in place to restore Barrier.
Green – Barrier effective.
Blue – Status is unknown.

When defining your Corrosion Management Framework (CMF), start by selecting the Degradation Mechanisms and their applicable Barriers.

The Indicators are automatically selected based on the Degradation Mechanism / Barrier type.

Adding Degradation Mechanisms

To add the Degradation Mechanism, first scroll to the Degradation Management section:

From the drop-down menu on the right select Board view.
Click the Plus button.
Select Board and click the plus button,
Select the applicable Degradation Mechanism(s).
Available Degradation Mechanisms.
Click OK.

Created Degradation Mechanisms will be shown on the Board.

Adding Barriers

Next we need to add applicable Barriers. To add a Barrier:

Click the Add new Barrier button on the Degradation Mechanism Card.

Click Add new Barrier to add a Barrier.
Click on the down arrow to display the options list.

Click on the Select a Barrier type and a list of available Barriers will appear.

Select the appropriate Barrier.

The Degradation Management Board will now show the Barriers and also their Indicators (when available).

Degradation Management Board with Degradation Mechanisms, Barriers and Indicators.

In the image above, it can be seen that for the "M01-Corrosion Allowance" Barrier the Indicator is "Corrosion Calc" with the color:
Red, if the Remaining Life (RL) is less than 5 years.
Amber, if the Remaining Life (RL) is between 5 and 10 years.
Green, if the Remaining Life (RL) is greater than 10 years.
If the Mitigated Equipment has not been specified yet, there will be no color on the Indicator and the "M01-Corrosion Allowance" Barrier will be colored blue.
For the "Atmospheric Corrosion" DM and "D-01 Coating" Barrier, there is no Indicator defined yet. This will be implemented and will be visible at a certain moment in the software.

For the Pipeline "OnshoreTest1_DM_CMF_IOW_Pipeline-Eq", which is part of the Pipeline System the Remaining Life (RL) is July 2027. This image is from July 2020, thus RL is between 5 and 10 years. If we assign the Pipeline to the Barrier, both the Indicator and the Barrier will be colored orange.

Assigning Mitigating Equipment

Proceed by adding the Equipment to the Barrier you created. To assign the Equipment:

Click Mitigated Equipment.

Mitigating Equipment on the Barrier card.

Select one (or more) pieces of Equipment from the Equipment list.
Select the Mitigating Equipment.
Click OK.
In the Degradation Management section click the Refresh button on the right.

The RL is 7 years, so this will result in the Indicator and Barrier being colored Amber:
The Barrier Status is Amber.

Barrier Details

To see the Barrier's details:

Click the vertical bar on the Barrier card. Note: The vertical bar (with its arrow) will be visible when you hover the mouse over the Barrier card.

These details are:

Barrier Notes

Notes about the Barrier can be added to the Barrier card. To add the Notes:

Click the Note button:
Click the Note button to add a note.
Enter your Note in the text field
Click Save.
Click OK.

After you wrote and saved the Note, click OK to close the window.

Notes that have been added will be shown on the Degradation Management Board under Notes.

Indicators

The system currently has four types of indicators:

Corrosion Calc Indicator
ECH Code Indicator
Spec Indicator
Process Data Indicator

Corrosion Calc Indicators

The "Corrosion Calc" Indicator is configured to check the Remaining Life (RL) of the selected Mitigated Equipment.

In the previous section we had a "Corrosion Calc" Indicator for "Atmospheric Corrosion" DM with Barrier "M01-Corrosion Allowance" with color configuration:
Red, if the Remaining Life (RL) is less than 5 years.
Amber, if the Remaining Life (RL) is between 5 and 10 years.
Green, if the Remaining Life (RL) is greater than 10 years.

ECH Indicators

The ECH Indicator is configured to check the Conditions Found in an ECH and the Condition Date of the ECH. The Indicator colours will correspond to the Inspection Findings.

For the Degradation Mechanism "CUI-CS" with "D-01 Coating or Painting" Barrier, the "Coating or Painting" Indicator is shown:
Coating or Painting Indicator for the Degradation Mechanism CUI-CS and D-01 Coating or Painting Barrier.

Spec Indicators

These Indicators check that data is available in the Specs.

For example: For the Resistant Material, the Indicator checks if a BASE MATL Spec is defined on the Equipment level.

Process Data Indicators

These Indicators will check the Process Data Variable. For the combination of the Degradation Mechanism and Barrier Type, it is possible to have suggested IOW Variables to use. For more information see Linking IOWs to Barriers.

Indicators Examples

In July 2020 the below two Indicator Types have been implemented.

1. Indicator Type: Corrosion Calc

For Degradation Mechanisms:

Atmospheric Corrosion
HF Acid
Oxygen Corrosion
Sulphidic Corrosion
Orig Acid Corrosion
Wet CO2 Corrosion
Erosion Corrosion

And with Barrier Type:

M-01 Material selection with Indicator Type Corrosion Allowance

The Remaining Life (RL) of the selected Mitigated Equipment will be checked. The color is set to:

Red, if the Remaining Life (RL) is less than 5 years and the Remaining Life (RL) is less than the required life
Amber, if the Remaining Life (RL) is between 5 and 10 years and the Remaining Life (RL) is less than the required life
Green, if the Remaining Life (RL) is greater than 10 years and the Remaining Life (RL) is greater than the required life

2. Indicator Type: Deteriorated Insulation

For Degradation Mechanisms:

CUI-CS
CUI-SS

And with Barrier Type:

D-01 Coating and Liners with Indicator Type Deteriorated Insulation

The ECH code and ECH date will be checked. The color is set to:

Red, Deteriorated insulation = Yes, possible CUI.
Amber, Deteriorated insulation ≠ Yes, possible CUI and ECH Date > 5Y.
Yellow, Deteriorated insulation = Yes, possible CUI but CAIR in place.
Green, Deteriorated insulation ≠ Yes, possible CUI and ECH Date < 5Y.

Integrity Operating Window (IOW)

In the IOW section, a Variable with the minimum and maximum values can be specified. This Variable can be linked to a Barrier. If the Variable is in PI then data can be extracted from PI and checked against these minimum and maximum values.

For more information on the IOW see IMS Integrity Operating Window (IOW).

Linking IOWs to Barriers

For some Barriers, it is possible to define the IOW to monitor.

Barrier types that can be linked to IOWs are:

P-02 Flow Control
Chemical Treatment

To link an IOW to a Barrier:

Click the vertical bar on the Barrier card to open the Barrier Details .
Click on the Search in the Barrier IOW field.
Select the applicable Variable (or first define a new IOW if needed - see Creating and Defining IOWs).
Click OK.
