QRA Quantitative Risk Assessment
Course Description

The Quantitative risk assessment participants will Learn how to evaluate risk using the Quantified Risk Analysis (QRA) method – the numerical combination of severity of consequence with frequency of event.

This course will helps in better understanding different types of risk and how they are calculated. participants will learn how to select scenarios to be modelled, and how to determine appropriate data as inputs. It will explore how risk results are interpreted and how QRA can be applied to practical engineering solutions. Demonstrations of Occupied Building Risk Assessment and As Low As Reasonably Practicable (ALARP) will be provided. The course will use a mix of theory, practical exercises, and discussion.

The following learning objectives outline the key skills and knowledge participants will gain through this training course:

-The definitions of risk

-how to select cases to be modelled

-how to build a QRA model

-how to calculate risk and interpret the results.

This training course aims to achieve the below goals:

-Enhance understanding of risk: Learn to define, quantify, and analyze risk in various scenarios.

-Develop technical skills: Build QRA models, calculate risks, and interpret results effectively.

-Foster practical applications: Apply QRA findings to real-world engineering challenges.

-Promote best practices: Explore the limitations of QRA and learn how to adhere to industry standards.

-Support safety initiatives: Gain insights into tools like Occupied Building Risk Assessment and As Low As Reasonably Practicable (ALARP) demonstrations

-Reading and understanding the different QRA report

-Interpret software result

-Quick tour in DNV phase and safety software

The course is designed for:

1.Process Safety Engineers

2.Safety Managers

3.HSE (Health, Safety, and Environmental) Professionals

4.Risk Assessment Teams

5.Consultants who working in process safety and risk management fields

The course is designed to be delivered over 5 days; the following breakdown outlines the key topics that will be covered throughout the duration of the course:
