In this succinct SlideShare presentation, audiences are introduced to two critical concepts in the oil and gas industry: Process Hazard Analysis (PHA) and Hazard and Operability Study (HAZOP). Over six information-laden slides, the relationship and differences between PHA and HAZOP are explored, alongside showcasing the various methods employed in PHA, the applications of HAZOP, and its unique role in ensuring safety considerations are considered right from the design stage.

1. PHA vs HAZOP:
Understanding Key Concepts in the
Oil and Gas Industry

2. What is PHA
Process Hazard Analysis (PHA): Examines processes to identify hazards and assess risks
Aims to manage and mitigate risks effectively

3. Methods Used in PHA
Layer of Protection
Analysis (LOPA)
Hazard and Operability
Study (HAZOP)
Failure Modes and Effects
Analysis (FMEA)
What-If Analysis

4. More Methods
Used in PHA
Fault Tree
Analysis (FTA)
Bow Tie Analysis Hazard Identification
(HAZID)

5. What is HAZOP
HAZOP: A specific method within PHA for
identifying deviations from design
Uses guidewords for systematic analysis

6. The Role of HAZOP within PHA
Focuses on analysing process systems and deviations
Proposes preventive or mitigative measures
Ensures safety considerations are integrated from the design stage
