The operating challenge
Completed work orders alone do not demonstrate that a barrier can perform its required function. Asset managers need a clear view of performance requirements, test evidence, impairments and the actions needed to maintain protection.
Service offers
Barrier and SCE assurance review
Review the link from existing hazard studies to safety-critical elements (SCEs), their required functions and performance standards. Identify gaps in coverage or ownership.
Assurance-task and evidence review
Check whether inspection, maintenance and test tasks demonstrate the required performance. Connect evidence and exceptions to the relevant barriers.
Impairment and action governance
Review degraded-barrier records, escalation, compensating measures and action closure. Establish a practical management view of barrier status.
What the domain covers
Process safety protects against major-accident scenarios. ReliaEdge’s core contribution is the connection between hazard studies, critical barriers, performance requirements and operating assurance.
01Hazard basis and barrier traceability+
- Review the available process information, hazard studies and major-accident scenarios.
- Connect preventive and mitigative functions to equipment and operating controls.
- Identify gaps requiring specialist hazard review rather than assuming study completeness.
02Safety-critical elements and performance standards+
- Document SCE selection, system boundaries, required functions and responsibilities.
- Define measurable performance expectations and the evidence needed to demonstrate them.
- Maintain traceability when equipment or operating conditions change.
03Assurance tasks and evidence+
- Check inspection, maintenance and test coverage against required barrier functions.
- Review task results, acceptance criteria, exceptions and evidence quality.
- Connect failed tests and overdue tasks to the barrier status and action register.
04Functional-safety interfaces+
- Review the links between SIF requirements, proof-test records and operating constraints.
- Track demands, failures, bypasses and changes for competent specialist review.
- SIL determination, verification and SIS design require a separately agreed specialist scope.
05Impairment and operating controls+
- Register degraded or unavailable barriers and the affected scenarios.
- Connect temporary measures, authorization, escalation and restoration actions.
- Make unresolved impairments visible to the responsible operational authority.
06Change, readiness and handover+
- Review the effect of modifications on barrier requirements and assurance tasks.
- Confirm outstanding actions, responsibilities and records at handover.
- Link process-safety information to operating procedures and competence needs.
07Indicators and learning+
- Use a balanced view of events, demands, barrier weaknesses and assurance activity.
- Agree definitions and thresholds appropriate to the operation.
- Investigate recurring weaknesses and verify the effectiveness of closure.
ISO 10418 applies to offshore surface process-safety systems. IEC 61511 provides the SIS lifecycle reference. API RP 754 addresses process-safety indicators for refining and petrochemicals; specialist studies are scoped explicitly.
What we work with
Hazard studies, bow ties, tag registers, existing standards, test records and impairment history.
The decision this supports
Better visibility of barrier condition and a clearer basis for managing major-accident risk.
How progress can be measured
Overdue safety-critical assurance tasks; unresolved impairments; evidence completeness; verified action closure.
Agree the baseline, definitions and review period with the asset team. Measures are selected for the scope; they are not guaranteed results.The core offer is barrier and SCE assurance. HAZOP, LOPA, SIL studies and specialist verification are separately scoped against competent resources.
Relevant engineering references
Applicable editions and requirements are agreed for each asset, jurisdiction and scope. These references describe the engineering basis; they do not imply ReliaEdge certification or endorsement by ISO or API.
AI support within this service
- Extract SCE references and evidence links from controlled documents.
- Flag missing assurance evidence and inconsistent barrier records.
- Group incident narratives to support expert-led learning.
Competent specialists approve hazard interpretations and barrier decisions. AI does not authorize safety-system changes.
