-
Hazard and Risk Assessment (HAZOPs)
Following the Hazards and Risk Assessment, the IEC 61511 safety lifecycle model requires that identified SIFs are assigned a target measure of their reliability to perform the safety function.
-
Safety Integrity Level (SIL) Selection
The challenges faced by facilities include accurately budgeting for process safety equipment and allowing for the protection of people and plant, while complying with government regulations. Through following the Hazards and Risk Assessment, the IEC 61511 safety lifecycle model requires that identified SIFs are assigned a target measure of their reliability to perform the safety function.
-
SIL Verification
SIL selection ensures legislative safety requirements are met prior to final plant design — avoiding costly redesign and rework of the process safety system — by determining the intended SIS design meets all safety targets specified in the SIL selection workshops.
-
Safety Requirement Specification (SRS) Service
The Safety Requirements Specification ensures that the safety specifications consider all aspects of process safety and that the SIS is designed and engineered to correct specifications prior to plant implementation.
-
Design and Engineering of the Safety Instrumented System
Once the Safety Requirements Specification has been produced, the next step is the design of the ProSafe Safety Instrumented System (SIS).
-
Safety Assessment and FSM Audit
Functional Safety Audit (FSA) should be carried out prior to plant start-up.
