Dependability in operation

Reliability, availability, ease of maintenance, safety: we optimize the operational safety of your industrial facilities to ensure their performance and continuity.

 Need support?

Operational Safety (SdF) encompasses all the methods and tools used to assess and optimize the reliability, availability, maintainability, and safety (FDMS) of industrial systems.

Our expertise

ISO Ingénierie provides its expertise in Operational Safety to conduct detailed FDMS studies of systems, subsystems, and equipment.

Requirements analysis and reliability study:

  • Identification and consideration of regulatory and standard requirements (IEC 61508, IEC 61511, MIL-HDBK-217, ISO 13849, etc.)

  • Definition of FMDS objectives based on operational needs

Risk assessment and quantification:

  • Criticality analysis (FMEA)

  • FMEA

  • Predictive reliability studies and failure rate calculations

Functional safety and failure analysis:

  • Fault Tree Analysis (FTA)

  • Safety Integrity Level (SIL) estimation

  • Definition of protective measures and recommendations for improvement

Optimization of maintenance and system availability:

  • Performance and availability modeling

  • Maintainability and maintenance logistics studies

  • Development of preventive and condition-based maintenance plans
