Training courses and seminars


2 days duration

Hazard Operability Study (HAZOP) is a structured and systematic examination of a planned or existing process or operation that allows to identify and evaluate any deviations that may represent risks to personnel or equipment; it is carried out by multi-disciplinary team (HAZOP team) during a set of meetings. The HAZOP technique is mainly qualitative, and aims to stimulate the imagination of participants to identify potential hazards and operability problems.


This 2-days workshop is designed to allow the attendants to be prepared in performing HAZOP sessions. This includes understanding the principles behind the method and the fundamentals on HAZOP methodology, noding, team composition and preparation for a HAZOP session. During the workshop participants will have the opportunity to simulate a mini HAZOP (exercise) from preparation of the drawings to facilitating and recording the analysis. By the end of the workshop participants will understand the key elements of HAZOP methodology, preparation, organization thus allowing them to fruitfully participate and contribute to future HAZOP sessions.

Who should attend?

  • Plant and Maintenance Managers, Key HSE Functions, Key Supervisors, Project Managers and Project Engineers responsible/involved in facilities’ HES management
  • Process engineers, Instruments & Control Engineers and other disciplines engineers required to participate to HAZOP studies


  1.  Introduction to Risk Management and Assessment
  2.  HAZOP background & Terminology (Origins of HAZOP, Explanation of terminology – parameter, deviation, guideword, study node, design intent, etc.)
  3. Applicable Codes & Standards (International, IEC)
  4. HAZOP in the life of a process plant (Design phase, Operating and standing Instruction, Refresher HAZOP, Pre modification HAZOP)
  5. Mechanics of the HAZOP Process (Defining Nodes, Application of a deviation to a study node, Examination of all possible causes, Evaluation of consequences of each cause, Evaluation of safeguards against each consequence, Conclusions and recommendations)
  6. Causes, Consequences and Safeguards (brainstorming causes, Logical development and extension of consequences, Critical assessment of adequacy of existing hard, soft and procedural safeguards, LOPA)
  7. HAZOP Team (Members, Roles and responsibilities, Depth and breadth of experience)
  8. Preparing for a HAZOP Study (When a HAZOP should be undertaken in according to Project Schedule, P&I Drawing status, identifying the team, Supporting documents, Venue, timing, duration).
  9. Recording HAZOP recommendation (Type of recommendation, Quality of recommendation, what, why, where, Traceability, follow up, sign off)
  10. Risk Ranking (Frequency and consequence matrices, Ranking Recommendations, why, when & who)
  11. Recording the Study (Role of recorder, Recording format, Simultaneous recording and team consensus, P&ID mark up and sign-off, Close-out Report)
  12. Other methods of Hazard Identification (Checklists, SWIFT, Failure Mode and Effects analysis, Generic failure- Quantitative Risk Assessment)
  13. Case study: HAZOP Exercise, including:

a.  Study preparation (team composition, collection of documentation);

b.  Selection of parameters and guidewords;

c.  Definition of nodes;

d.  Simulated HAZOP session.

The exercise will usually be customized on the customer specific field of application (Oil & Gas Upstream, Oil & Gas Downstream, Petrochemical industry etc.) using customer provided documentation (Process description, P&ID, layout etc.).


Training sessions will be basically held in English language, with translation of material and speeches in Turkish language.
