FAQ-HAZARD AND OPERABILITY STUDY (HAZOP)
The purpose of a HAZOP (Hazard and Operability) study is to identify potential hazards and operability issues in process facilities, aiming to reduce the likelihood and impact of incidents. This helps protect personnel, the plant, property, the environment, and the company's reputation.
METHODOLOGY FOR HAZARD OPERABILITY (HAZOP) STUDY
The purpose of HAZOP Study is to identify the hazard and operability problems and to reduce the probability and consequences of an incident in the process facilities that would have a detrimental impact to the personnel, plant, properties, environment and company reputation. This Method describes the organization, study methods and recording requirements for HAZOP studies. Its purpose is to advise both HAZOP team members and other members of a project, of the approach to be adopted as well as the other contributions required from individuals. It is based upon considered worldwide best practices and international benchmarks in HAZOP deployment and management.
METHODOLOGY FOR LOPA STUDY
The LOPA (Quantitative Technique) is based on establishing a tolerable frequency for each consequence resulting from an impact event. LOPA is a simplified form of risk assessment. LOPA typically uses order of magnitude categories for initiating event frequency, consequence severity, and the likelihood of failure of independent protection layers (IPLs) to approximate the risk of a scenario.
