HAZOP study in India | HAZOP consulting services India | Process safety design

A HAZOP study is used to verify the integrity of design or procedures with respect to safety and operability. HAZOP studies need extensive experience and highly skilled multi-disciplined teams.  Process Hazard Analysis is a systematic approach for identifying, evaluating, and controlling the hazards of processes.

Why HAZOP

HAZard and OPerability (HAZOP) is a well known and well documented study. HAZOP is used as part of a Quantitative Risk Assessment (QRA) or as a standalone analysis. The purpose of HAZOP is to investigate how the system or plant deviates from its original design intent and create risk for personnel and equipment and operability problems. The process hazard analysis methodology selected must be appropriate to the complexity of the process and must identify, evaluate, and control the hazards involved in the process.

HAZOP studies have been used with great success within chemical and the petroleum industry to obtain safer, more efficient and more reliable plants. HAZOP has become a standard method in the design of process system in India.

What HAZOP companies do

HAZOP companies have a strong and experienced pool of experts within technical safety. These experts have extensive experience with HAZOP both as part of the design of process plant either as an independent risk analysis or a preliminary study and modification. This also includes procedural HAZOPs.

A typical HAZOP study will be conducted this way:

  • Familiarization with background documentation
  • Planning of the workshop meeting in a pre-meeting with the customer in order to identify HAZOP strategy, division of the subsystems/nodes (e.g. line, pump, vessel, compressor), choose relevant Piping and Instrument Diagrams (P&ID), and identifying guide words
  • Accomplishment of the HAZOP review
  • Documentation of observations into information and actions point, document findings on the P&IDs.
  • Draft report for client review.
  • Final HAZOP report.

The process hazard analysis shall address the following:

  • The hazards of the process
  • The identification of any previous incident that had a likely potential for catastrophic consequences
  • Engineering and administrative controls applicable to the hazards and their interrelationships
  • Consequences of failure of engineering and administrative controls
  • Stationary source siting
  • Human factors and
  • A qualitative evaluation of a range of the possible safety and health effects of failure of controls.

A Process Hazard Analysis (PHA) team includes process safety specialist, engineers, operators, supervisors and other workers who have knowledge of the standards, codes, specifications and regulations which apply to the process being studied.
