Safety Assessment and FSM Audit

Functional Safety Assessments are mandatory to be carried out at 5 stages as per IEC 61511. Similarly, Functional Safety Audits are required to be carried out on plants’ FSM systems on a typically yearly basis.

Customer Challenges

To carry out independent Functional Safety Assessments (FSA) during operation as required in AS IEC 61511. To conduct periodic Functional Safety Audits.

Our Solutions

Regardless of the safety system ‘brand’ in place, a FSA is carried out prior to plant start-up. SIS Validation activities are reviewed for completeness and any technical deficiencies present in the prior IEC 61511 process safety phases are identified. Readiness of the plant to move into the next phase of the safety lifecycle is thoroughly and professionally assessed.

Our consultants conduct SIS Functional Safety Management (FSM) audits in the industry to ensure our clients have a compliant FSM System in place. Different areas of FSM are scrutinized to ensure the plant has adequate procedures and systems in place to comply with FSM requirements. An FSM audit is included as part of the Functional Safety Assessment prior to plant start-up.

In FSAs during the operational phase, we analyse if actual process safety indices and SIS performance are matching design assumptions. Identified weak links are addressed together with plant engineers to bridge any gaps, assuring safety is not compromised.
