6. MEANING OF HAZOP Study KAZTEC ENGINEERING LTD

7. Professional hazards: Every Project has its associated difficulties. Hence professional Hazards are inevitable. KAZTEC ENGINEERING LTD We need to know that: Hence, Planning positions you to deal with obstacles (Hazards).

8. HAZOP Means: HAZOP (Hazard and Operability Study ) Its a risk analysis tool which is used to identify KAZTEC ENGINEERING LTD abnormalities and its causes and consequences in more complicated or comprehensive processes or operations. In simple words,

9. to avoid hazardous unwanted incidents which may give rise to operability problems and may be significant in terms of damage to; Life (death or injuries ), KAZTEC ENGINEERING LTD Environment (environmental impact) or Property (fire, unsafe structures, collapse ). A STUDY THAT HELPS

10. MEANING OF HAZOP Study – cont’d HAZOP study is a structured and systematic examination of KAZTEC ENGINEERING LTD a planned or existing process operation in order to identify and evaluate problems that may represent risks to personnel or equipment, or prevent efficient operation.

11. 11 HAZOP A HAZOP study is a widely used method for the identification of hazards A HAZOP is a rigorous and highly structured hazard identification tool It is normally applied when PFDs and P&IDs are available The plant/process under investigation is split into study nodes and lines and equipment are reviewed on a node by node basis Guideword and deviation lists are applied to process parameters to develop possible deviations from the design intent HAZOP results in a very systematic assessment of hazards

12. History and development HAZOP Study KAZTEC ENGINEERING LTD

13. (history and development): The HAZOP study methodology was first introduced by engineers from ICI chemicals in the mid-1970s. KAZTEC ENGINEERING LTD ICI – imperial Chemicals Industries After over 25 years usage it is firmly established as the most widely used technique for identifying deviations from design intent and assessing the potential consequences .

14. (history and development): The HAZOP technique was initially developed to analyze chemical process systems, also; KAZTEC ENGINEERING LTD but has later been extended to other types of systems and also to complex operations and to even software systems. That leads us to

15. HAZop Study – cont’d When to perform HAZop Study? KAZTEC ENGINEERING LTD

16. HAZop Study – cont’d When to perform HAZop Study? The HAZOP study should preferably be carried out as early On the other hand ; to carry out a HAZOP we need a rather complete design. KAZTEC ENGINEERING LTD in the design phase as possible - to have influence on the design. As a compromise , the HAZOP is usually carried out as a final check when the detailed design has been completed.

17. HAZop Study – cont’d A HAZOP study may also be conducted KAZTEC ENGINEERING LTD On an existing facility to identify modifications that should be implemented to reduce risk and operability problems .

18. HAZOP studies may also be used more extensively, including: At the initial concept stage when design drawings are available (conceptualization stage). KAZTEC ENGINEERING LTD When the final piping and instrumentation diagrams (P&ID) are available.

19. When to perform OF HAZop Study – cont’d During construction and installation to ensure that recommendations are implemented KAZTEC ENGINEERING LTD During commissioning During operation to ensure that plant emergency and operating procedures are regularly reviewed and updated as required.

20. NOW LETS LOOK AT HAZID KAZTEC ENGINEERING LTD

21. MEANING OF HAZid Study KAZTEC ENGINEERING LTD

22. HAZid : HAZID means (Hazard Identification) KAZTEC ENGINEERING LTD It’s a general risk analysis tool for early identification of hazards or threats , where the purpose is to identify possible unwanted incidents within a discipline, operation or area.

23. HAZid : These possible incidents are classified with respect to consequences and probability . KAZTEC ENGINEERING LTD Measures are then implemented in order to reduce the risk to an acceptable level. Unwanted incidents That leads us to

24. When to perform HAZid Study? KAZTEC ENGINEERING LTD

25. HAZid Study – cont’d When to perform HAZid Study? HAZID studies follow a very similar format to HAZOP s, although a different set of guidewords are used. KAZTEC ENGINEERING LTD HAZIDs are usually conducted prior to the start of detailed design of a process and are typically used to identify major hazards likely to impinge on the process under review.

26. HAZid Study – cont’d Typical HAZID guidewords or phrases can include: Hazid, guidewords KAZTEC ENGINEERING LTD Fire , Explosion , Dropped loads , Environmental conditions and Human factors. A HAZID is sometimes known as a HAZOP I study.

27. Sometimes, that means they can be used interchangeably depending on the terrain and circumstances. As far as I know KAZTEC ENGINEERING LTD Types of hazop study

28. Types of HAZop Study Process hazop KAZTEC ENGINEERING LTD human hazop Procedure hazop software hazop

29. Types of HAZop Study – cont’d This HAZOP technique was originally developed to assess plants and process systems. Process hazop human hazop A “family” specialized HAZOPs. More focused on human errors than technical failures. KAZTEC ENGINEERING LTD

30. Types of HAZop Study – cont’d Review of procedure or operational sequence sometimes denoted SAFOP – SAFe OPeration study. Procedure hazop software hazop This HAZOP reveals the identification of possible errors in the development of a software. KAZTEC ENGINEERING LTD

31. Other methodology KAZTEC ENGINEERING LTD

32. Hazan studies KAZTEC ENGINEERING LTD Meaning “Hazard analysis” HAZ- ard AN- alysis = HAZ + AN

33. HAZan Study The term HAZard ANalysis (HAZAN) covers a range of techniques which are, as the phrase implies, U sed to analyze hazards. KAZTEC ENGINEERING LTD Typically , this includes analyzing the consequences of hazards and the safeguards for hazard prevention and / or mitigation . Many hazard techniques have been developed for a variety of different end requirements.

34. HAZan Study - cont’d Those that have gained most widespread use are : KAZTEC ENGINEERING LTD Fault Tree Analysis (FTA ) Event Tree Analysis (ETA ) Failure Modes, Effects and Criticality Analysis (FMECA)

35. HAZan Study software related packages “ Risk Spectrum PSA Professional” by Relcon KAZTEC ENGINEERING LTD “ PHA Professional” by Dyadem , “ Fault Tree Plus” by Isograph and - “ RAMP” by Advantage.

36. Hazop/hazid management During the development of a large upstream oil and gas project , there is a need for third party reviews. KAZTEC ENGINEERING LTD This might be in the form of a hazard and operability study ( HAZOP ) and hazard identification ( HAZID ) study, or in the form of process design reviews, safety reviews and so forth.

37. Hazop and hazid facilitation KAZTEC ENGINEERING LTD

38. Hazop and hazid facilitation Risk Assessment Workshops can be conducted at all phases of the Oil and Gas EPC Pipeline or KAZTEC ENGINEERING LTD Process facility project’s life-cycle to identify potential hazards associated with a system(s) and initiate appropriate control measures to either eliminate them , or reduce their risk to a level that is acceptable.

39. Hazop and hazid facilitation Workshop results can be captured in a hazard log, or hazard tracking system (such as SITREP) for easy translation into a post workshop action plan . KAZTEC ENGINEERING LTD Well facilitated risk assessment workshops can ensure the effective engagement and input of all stakeholders, produce coherent and practical action plans , and minimize the risks to project cost and schedule.

40. Significance of Hazop / hazid studies KAZTEC ENGINEERING LTD therefore for an oil and gas epc pipeline and process facilities project.

41. Its Significance therefore The hazards of the process identifies the following: KAZTEC ENGINEERING LTD The identification of any previous incident which had a likely potential for catastrophic consequences in the workplace . 3. Engineering and administrative controls

42. Its Significance therefore Consequences of failure of engineering and administrative controls identifies the following: KAZTEC ENGINEERING LTD 5 . Facility siting 6 . Human factors and 7. A qualitative evaluation of a range of the possible safety and health effects of failure of controls on employees in the workplace.

43. Its Significance therefore 8. A good HAZOP study is also used as an input for proceeding with Layers of Protection Analysis. KAZTEC ENGINEERING LTD It must be remembered that a good HAZOP study is only as good as the skills of the facilitator and team members .
