Change the State of a LOPA

If a LOPA is used for SIL assessment of an Instrumented Function, a LOPA Assessment record is created and associated with the LOPA. When you change the state of a LOPA to Complete, the associated LOPA Assessment is also updated. Any change to the LOPA Assessment will also affect the associated Instrumented Function and Protective Instrument Loops. Therefore, if the LOPA is linked to a LOPA Assessment of an Instrumented Function in a SIL Analysis, then to change the state of the LOPA to Complete, the SIL Analysis and the associated PILs must be in a modifiable state.

• The SIL Analysis must be in the Planning state.
• The Protective Instrument Loops associated with the Instrumented Function must be in the Design state.

1. Access the LOPA whose state you want to change.

2. In the upper-right corner of the LOPA Summary workspace, select the button that indicates the current state of the LOPA. For example, if the current state of the LOPA is Planning, select Planning.

   A menu appears, displaying the list of operations that you can perform on the LOPA to change its state.

   

   Note: You can view the states assigned to various users by selecting the Manage State Assignments link. If not already done, you can assign the next state of the LOPA to the appropriate user, and then select Done.

3. Select the necessary operation that will change the state of the LOPA, and then select Done. For example, if you want to change the state of the LOPA from Planning to Active, select Begin, and then select Done.

   The state of the LOPA is changed.

   If the LOPA is in the Pending Approval state and you selected the operation Accept, a message appears, indicating that when you change the state of the LOPA to Complete, the changes to the LOPA will update the values in the associated LOPA Assessment and the Protective Instrumented Loops.

   

   1. Select OK.

      If the associated SIL Analysis is not in the Planning state or the associated Protective Instrument Loops are not in the Design state, a message appears, stating that the state of the LOPA cannot be changed.

      

   2. Select OK.

      The state of the LOPA is not changed.

   -or-

   If the LOPA is not in Pending Approval state, the state of the LOPA is changed.
