RBI 581 ISO Risk Plot

About the RBI 581 ISO Risk Plot

The RBI 581 ISO Risk Plot is a graph that plots the SHE risk and financial risk of:

  • A single RBI 581 Risk Analysis.
  • All RBI 581 Risk Analyses in a process unit, asset, corrosion loop, or component. In this scenario, the risk data of all the analyses in Risk Completed, Accepted by ASM, Pending Approval, or Approved state are plotted on the graph.
    Note: The maximum number of Assets that than can be plotted on the RBI 581 ISO Risk plot is 10,000.

By default, the graph for the SHE risk appears. If you want to view the graph for the financial risk, you must select the Financial Risk tab.

For SHE risk:

  • Consequence of Failure (in square feet) is plotted on the horizontal axis, using a logarithmic scale.
  • Probability of Failure (in events per year) is plotted on the vertical axis, using a logarithmic scale.

For financial risk:

  • Consequence of Failure (in USD) is plotted on the horizontal axis, using a logarithmic scale.
  • Probability of Failure (in events per year) is plotted on the vertical axis, using a logarithmic scale.
Note: The units of measure can vary depending on the UOM Conversion Set that you use. For example, if you use the Metric conversion set, the Consequence of Failure will be measured in square meters instead of square feet.


By default, the RBI 581 ISO Risk Plot Analysis Overview and Component Overview will concurrently plot the RBI Date, Without Plan and With Plan risk data. In the Asset Overview, the Corrosion Loop Overview, and the Unit Overview, only the RBI Date risk data is plotted by default. If you want the Without Plan risk or the With Plan risk data to be plotted, you can select the appropriate option from the legend box besides the graph.

Note: If the components within a Process Unit, an Asset, and the Corrosion Loop have the same Risk values on RBI Date, Without Plan, and With Plan, the graph plots will overlap with each other. In this case, you can navigate to ISO Risk of an individual component to see the details.

The background color for various sections in the graph indicate the risk levels as defined by the International Organization for Standardization (ISO).

The graph plots for RBI Date, Without Plan and With Plan are defined in the legend of the graph. You can hide or unhide the risk plots by selecting or deselecting the respective risk plot icon in the legend of the graph.

If you hover over a data point, then the ID of the analysis, the ID of the associated asset, the consequence of failure, probability of failure, and risk data of the analysis appear. If you select the data point, the Asset Summary page appears, displaying the analysis datasheet in the Analysis Details section.

To clearly distinguish the risk plots on a section of the graph, you can zoom-in the section by selecting that area of the graph using the cursor.

Note: If you want to specify a different set of values to be plotted on this graph, or modify the ranges for each axis and risk level, then access the RBI 581 ISO-Risk Plot Preferences workspace.

    Note: By default, the risk on the RBI date is plotted. If you want the Without Plan risk or the With Plan risk data to be plotted, select the appropriate option from the legend box besides the graph.
  4. If you want to view the Financial Risk, then select the Financial Risk radio button.
  5. If you want to access the datasheet of the analysis that corresponds to a data point, then select the data point.
  6. If you want to select a different functional location, then:

    1. On the upper-left corner of the page, select .

      The Enter Parameter Values window appears.

    2. Select the process unit that is already set as the context.

      The Hierarchy window appears.

    3. Navigate to the process unit whose ISO risk plot you want to access, and then select Done.

      The Hierarchy window closes.

    4. On the Enter Parameter Values window, select Done.

      The ISO risk plot for the selected functional location appears.
