Critical Thinking At Gate Pass Safety Reviews

What Project Managers Should Look for in HAZOPs?

‘‘ A gate-pass review should change the project's decision position: it authorises expenditure, releases procurement, confirms the design basis. It must therefore be judged against the decisions the project is about to make — not the activities shown in the schedule’’.

LIFECYCLE THINKING

Focusing on Decisions Rather than Activities

Aligning technical risk management with plant design phases builds on the same principle — each phase exists to mature a specific set of decisions, and its risk activities exist to inform those decisions at the right level of detail.

Early HAZOP or Premature Assurance?

18 Warning Signs of a Weak or Premature Safety Review.

INTEGRATION OF ACTIONS TO DESIGN LIFE-CYCLE AND TRACEABILITY

A design based recommendation given in HAZOP for modifications may be minor at equipment level but may create major effects elsewhere:

  • Additional relief loads may exceed flare-system capacity

  • Depressurisation may create low-temperature material risks

  • A new shutdown function may conflict with package controls or isolation sequence

  • A structural change in a line may trigger surge and etc.
