SIF Analysis

This online manual explains the SIF Analysis module in IMS SIS: How the SIF Analysis fits into the Safety Life Cycle . How to interpret and use the Analysis Main Screen (grid list). How to create a new SIF Analysis. How to determi...

The SIF Analysis Details Page is used to record the SIF Analysis details. The SIF design itself mainly takes place on the Design Tab . The Aim The aim is to design the Subsystems in terms of their  Equipment Actuators and Test Inter...

The Analysis Main screen shows an overview grid, with a list of SIF Analyses. Listing SIF Analyses (the Overview Grid) To see the list of SIF Analyses: Click to the SIF Analysis Main Menu. Click on the SIF Analysis Main menu, to list all...

Often a SIF Analysis will be created from a LOPA and will then automatically be connected to that LOPA. Alternatively, a SIF Analysis can be created independent from a LOPA, e.g., when you have an emergency button. In this case, you can connect it t...

The aim of a SIF Analysis is to design the Subsystems such that the Achieved PFD is equal or higher than the Target PFD . The Target PFDs are typically established during the LOPA study. In some cases, a SIF Analysis can be started independen...

When the SIF design is Approved , the selected  Tests  (with their Test intervals) must be assigned to the associated Equipment’s Schedules to ensure the SIF achieve the Target PFD . This is typically not a task for the SIF designer. ...

A Safety Requirements Specification (SRS) Report (see  IEC Compliance ) can be generated per Unit for all SIFs with a Final Approved SIF Analysis. This can be done from any IMS SIS Main Screen or Details Page. Generating the SRS Report fro...
