  2. 2. ARE THERE GOOD AND BADHAZOPS? 3
  3. 3. HAZOPCommonly observed practices  Preparation  Team members with the right experience  Experienced facilitatorHAZOP Quality  Audit  ObserverHAZOP is an opportunity to brainstorm about risks. Any effort to structure this further makes the HAZOP process boring, tedious, and takes away the imaginative thinking. 4

  5. 5. BEFORE HAZOP 6
  6. 6. Documentation 7
  7. 7. Team SelectionHAZOP is affected by  Knowledge-base  Group interactionSuggested Practice  Selection of team members should be based on professional background as well as personalities  Revalidation  Try bringing in new team members during HAZOP revalidation  Bring in professionals with requisite professional background who have not been involved in the process being HAZOPed 8
  8. 8. Facilitator SelectionCommon selection criteria  Experience  Knowledge of the process  Leadership and management skillsRecommended Practice  Neutral personality  Ability to engage team  Inquire with team members from past HAZOPs  Interview the facilitator 9
  9. 9. DURING HAZOP 10
  10. 10. HAZOP ProceedingDocumentation (P&IDs, PFDs, Projected material) should be visible to all HAZOP membersDual projectors for supporting documentationUse 3D views of the plant/process if available during a HAZOP  Visualization keeps the team engaged and helps stimulate discussions. 11
  11. 11. HAZOP Proceeding6-hour of HAZOP day is recommendedFor a HAZOP that may go beyond four weeks, we suggest a break between the HAZOP  Spending additional time may help you meet the schedule but the team may be going through the motions of HAZOP and sacrificing qualitySufficient breaks between sessions 12
  12. 12. HAZOP ProceedingWe suggest a HAZOP team up to 10 peopleRelevant case studies to energize the HAZOP team and keep discussions livelyProvide a mechanism for HAZOP members to provide feedback anonymously during the study period 13
  13. 13. HAZOP ProceedingManaging group dynamics  Group thinking  False consensus 14
  14. 14. AFTER HAZOP 15
  15. 15. FeedbackFeedback from HAZOP members  Ask them about  Documentation  Arrangements  Facilitator  Duration  SuggestionsFeedback forms 16
  16. 16. HAZOP RecommendationsRecommendations must be clear, concise, unambiguous, and relevant 17
  17. 17. Closing Out of RecommendationsA HAZOP recommendation may have multiple “actions”  Treat each HAZOP recommendation as a project  Identify the embedded project and actions  Use a simple project management application  E.g. Deskaway  $25/month 18
