Advanced HAZOP Analysis

Advanced HAZOP (Hazard and Operability) Analysis is a structured and systematic methodology used to identify potential hazards, operability issues, and risks in complex industrial processes, particularly in the oil and gas, chemical, petrochemical, and energy sectors. While traditional HAZOP focuses on identifying deviations from design intent, advanced HAZOP extends this approach by incorporating modern tools, techniques, and methodologies to address emerging challenges such as cyber threats, human factors, and dynamic process conditions. This course is a comprehensive overview of advanced HAZOP analysis, including its principles, methods, applications, and best practices.

Audience

This course is aimed at all personal involved in PHA-HAZOP process such as:

Operation engineers, Process engineers, Chemical Engineers
Design, mechanical, electrical, civil & structure engineers
Maintenance engineers
Safety, HSE, Q/C & internal auditors
Planning personnel to be better understand the HAZOP

Course objectives

The objectives of this course are to:

Identify and mitigate risks associated with hazardous materials, high-pressure systems, and reactive chemicals.
Cybersecurity
Define human factors
Evaluate the impact of human error, training gaps, and procedural deficiencies on process safety.
Dynamic Systems
Analyze transient conditions, startups/shutdowns, and abnormal operating scenarios.
Emerging technologies
Address risks introduced by automation, robotics, AI, and digital twins.
