Create a LOPA From a Consequence

This topic describes how to create a LOPA from a Consequence.

When you create a LOPA from a Cause-Consequence pair in Hazards Analysis, the LOPA that is created is automatically linked to the Consequence. You can also create a LOPA from the LOPA module in GE Digital APM.

Note: You can create, or link a LOPA to a Consequence only if the associated Hazards Analysis is in the Planning State.

Steps

Access the System/Node that is linked to the Consequence that you want to access.
Select the Hazards Worksheets tab.

The Hazards Worksheets section appears, displaying a hierarchical view of the components (Deviations or What Ifs, Causes, Consequences, and Safeguards) associated with the System/Node.
Select the Consequence for which you want to perform the LOPA.
In the Consequence that you selected, select Create.

Note: If a Consequence is already linked to a LOPA, the links Edit and Unlink appear. You can either select another Consequence, or unlink the LOPA from the Consequence, and then create a new LOPA for the Consequence.

A blank datasheet for LOPA appears, displaying the Definition section.

Note: The Initiating Event field and the Frequency of Initiating Event field in the LOPA record are populated with the values in the CCPS Cause Type field and Cause Frequency (per year) field in the Hazards Analysis Cause record associated with the Consequence.
As needed, enter values in the available fields.
In the upper-right corner of the Definition section, select .

The LOPA is created.

Note: You can select Edit to modify the LOPA, or Unlink to unlink the LOPA from the Consequence.

Results

The LOPA is linked to the Consequence and the LOPA ID appears in the Consequence. You can select the LOPA ID to view the summary of the LOPA.
The LOPA that you created for the Consequence appears in the list of LOPA in the LOPA Overview page, in the Under Review tab.
The Safeguards that are associated with the LOPA are automatically linked to the Consequence. They appear in the Hazards Worksheet section of the Hazards Analysis. Similarly, the Safeguards that are associated with the Consequence are automatically linked to the LOPA. Hence, you can modify the Safeguard only if the associated LOPA and the Hazards Analysis are in the Planning state.
