Safety Instrumented System (SIS) Modification Services performed by Emerson consultants will help ensure straightforward, predictable, and documented modifications in accordance with the IEC61511 Safety Life Cycle. These services simplify your modification process as you meet compliance.
Staying current with process changes, technology, and operational best practices often requires modifications to your safety instrumented system (SIS). A carefully developed and executed plan—that abides by the IEC 61511 Safety Life Cycle— is key to successful implementation.
Provide verification of the modification: After the modification to your SIS has been implemented, the accuracy is verified with the SIS Modification Service. Our service offers simulated testing without impacting the process.
Ensure complete audit trail:Per the IEC 61511 Safety Lifecycle, Emerson uses detailed procedures to ensure that all modifications are documented properly. Emerson also assists with updating your system in the Safety Management System (SMS) to ensure that all future support calls will be based on your latest system information.
Deliver predictable SIS Modifications: Emerson’s SIS Modification Service includes an impact assessment of changes to ensure all effects are known and accommodated for. Emerson works with maintenance and operations staff to ensure the modification is effective and accounts for all planned facility shutdowns.
Reduce risk, minimize downtime: During modifications, Emerson engineers ensure risks are properly identified and contingency plans are in place should issues occur. When intentional shutdowns or bypassing of systems is required, Emerson strives to minimize downtime.
