To open a Systems Details Page, click on the desired System ID hyperlink in the [System Main Screen](/v410/docs/systems-main-menu) (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. ![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/Screenshot_15.jpg?sv=2026-02-06&spr=https&st=2026-10-28T18%3A44%3A28Z&se=2026-10-28T19%3A44%3A28Z&sr=c&sp=r&sig=d8Fqb2HtQ5Weaszura4fyLPOZH39A811zjb9bP9KfkU%3D) For more information on the icons see [IMS Details Page](/v410/docs/ims-details-page-options). The sections, listed in blue, are common to all Equipment Groups. For more information on these see [PLSS Equipment](/docs/plss-equipment-1), as well as [IMS Details Page](/v410/docs/ims-details-page-options). 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. ![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/sys-temp-image-mvxbq0ud(2).png?sv=2026-02-06&spr=https&st=2026-10-28T18%3A44%3A28Z&se=2026-10-28T19%3A44%3A28Z&sr=c&sp=r&sig=d8Fqb2HtQ5Weaszura4fyLPOZH39A811zjb9bP9KfkU%3D) Click the plus button. - An overview of all Equipment will be shown. - Select all the Equipment that should be added to the PLSS System. ![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/Screenshot_17.jpg?sv=2026-02-06&spr=https&st=2026-10-28T18%3A44%3A28Z&se=2026-10-28T19%3A44%3A28Z&sr=c&sp=r&sig=d8Fqb2HtQ5Weaszura4fyLPOZH39A811zjb9bP9KfkU%3D) Select all the Equipment that is part of this System. - Click **OK**. The selected Equipment will be shown in the Equipment grid. ![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/Screenshot_18.jpg?sv=2026-02-06&spr=https&st=2026-10-28T18%3A44%3A28Z&se=2026-10-28T19%3A44%3A28Z&sr=c&sp=r&sig=d8Fqb2HtQ5Weaszura4fyLPOZH39A811zjb9bP9KfkU%3D) 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. ![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/sys-temp-image-taqsnpmr(1).png?sv=2026-02-06&spr=https&st=2026-10-28T18%3A44%3A28Z&se=2026-10-28T19%3A44%3A28Z&sr=c&sp=r&sig=d8Fqb2HtQ5Weaszura4fyLPOZH39A811zjb9bP9KfkU%3D) Degradation Management Board view. 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. ![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/degradation-mechanism.jpg?sv=2026-02-06&spr=https&st=2026-10-28T18%3A44%3A28Z&se=2026-10-28T19%3A44%3A28Z&sr=c&sp=r&sig=d8Fqb2HtQ5Weaszura4fyLPOZH39A811zjb9bP9KfkU%3D) Degradation Management process steps. When defining your Corrosion Management Framework (CMF), start by selecting the Degradation Mechanisms and their applicable Barriers.

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: > > ![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/sys-temp-image-8v1tboxz.png?sv=2026-02-06&spr=https&st=2026-10-28T18%3A44%3A28Z&se=2026-10-28T19%3A44%3A28Z&sr=c&sp=r&sig=d8Fqb2HtQ5Weaszura4fyLPOZH39A811zjb9bP9KfkU%3D) > > 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. > > ![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/sys-temp-image-46j8xa7c.png?sv=2026-02-06&spr=https&st=2026-10-28T18%3A44%3A28Z&se=2026-10-28T19%3A44%3A28Z&sr=c&sp=r&sig=d8Fqb2HtQ5Weaszura4fyLPOZH39A811zjb9bP9KfkU%3D) > > A Spec Indicator. #### 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](/v410/docs/plss-systems-details-page#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. ![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/sys-temp-image-p3jekql3.png?sv=2026-02-06&spr=https&st=2026-10-28T18%3A44%3A28Z&se=2026-10-28T19%3A44%3A28Z&sr=c&sp=r&sig=d8Fqb2HtQ5Weaszura4fyLPOZH39A811zjb9bP9KfkU%3D) The Integrity Operating Window Section. For more information on the IOW see [IMS Integrity Operating Window (IOW)](/v410/docs/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](/v410/docs/plss-systems-details-page#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](/v410/docs/creating-iows)). - Click **OK.** ![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/sys-temp-image-z9atgd5d.png?sv=2026-02-06&spr=https&st=2026-10-28T18%3A44%3A28Z&se=2026-10-28T19%3A44%3A28Z&sr=c&sp=r&sig=d8Fqb2HtQ5Weaszura4fyLPOZH39A811zjb9bP9KfkU%3D) Steps to link the Barrier to the IOW. ### ## Schedule The Schedule section shows a list of Schedules for all of the Equipment in the PLSS System. ![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/Screenshot_21.jpg?sv=2026-02-06&spr=https&st=2026-10-28T18%3A44%3A28Z&se=2026-10-28T19%3A44%3A28Z&sr=c&sp=r&sig=d8Fqb2HtQ5Weaszura4fyLPOZH39A811zjb9bP9KfkU%3D) A list of schedules for the Equipment in the PLSS System.
