LOPA Workflow

This workflow provides the basic, high-level steps for using the Layers of Protection Analysis module. The steps and links in this workflow do not necessarily reference every possible procedure. For more procedures, see the links in the Related Information section.

Create a Layers of Protection Analysis by defining the type of Initiating Event, the required mitigated consequence frequency, and the probability of the enabling event. You can also associate the LOPA with a Functional Location and an Equipment.
Create Conditional Modifiers and define their probabilities.
Create Safeguards by defining the Safeguard type and linking an Asset to the Safeguard.
Specify a Safeguard as an Independent Protection Layer (IPL).
Evaluate the results by viewing the summary in the LOPA Summary workspace of the LOPA.
