Process Safety

Process Safety

HAZID, HAZOP, LOPA, SIL and Functional Safety to IEC 61508 and IEC 61511.

Process Safety is our specialism and the reason for the company name. We facilitate HAZID and HAZOP workshops, carry out LOPA, determine and verify SIL targets, and deliver Functional Safety work to IEC 61508 and IEC 61511. We do this as a standalone service for existing plants, and as an integrated thread through every FEED and EPCm project we run.

When you need this

Typical trigger points

  • A new or modified plant needs a structured hazard and risk assessment.
  • Existing Safety Instrumented Functions need SIL verification or reassessment.
  • A regulator, insurer or parent company has asked for a gap against IEC 61511.

What's included

Deliverables

  • HAZID and HAZOP facilitation and reports
  • LOPA studies and risk-reduction allocation
  • SIL determination and SIL verification
  • Functional Safety Assessment (FSA) reports
  • Bowtie analysis and barrier management
  • Pre-Startup Safety Review (PSSR) and SIMOPS reviews
  • Process safety management (PSM) gap assessments

  3. 3

    Facilitate

    Workshops chaired by a registered functional safety engineer.

  4. 4

    Analyse

    LOPA, SIL determination or verification against the study findings.

  5. 5

    Report & close-out

    Report issued, actions tracked to closure, FSA updated.

Standards we work to

Functional safety lifecycle.

IEC 61508

Generic functional safety standard for electrical / electronic / programmable safety systems, the foundation for safety-related equipment across sectors.

IEC 61511

Process-sector application of IEC 61508, covering the full safety lifecycle for Safety Instrumented Systems in chemical, oil & gas and power plants.

Tools we use: PHA-Pro, exSILentia and equivalent packages as required.
