Quantitative Risk Assessment, QRA
Date: 17th September 2019, Tuesday
Time: 3pm SGT
Ensuring the overall safety performance of your facility is the key to reduce the risk to human life, assets, environment and keep business interruptions to as low as reasonably practicable. Quantitative Risk Analysis (QRA) is widely used in industries involved with complex technical systems with potential for major accidents such as nuclear power plants, offshore installations and high hazard process facilities. This contributes to a safe design and optimised use of resources for controlling risk.
Registration is now closed.
The Quantitative Risk Assessment (QRA) is an appropriate tool for global industry-entailed hazards assessment. A QRA aims to define the numerical risk – a term that combines the frequency that a specified undesired event will occur and the severity of the consequences of the event – in order to compare it with the acceptance criteria of the country where the plant is located.
The numerical risk intends to quantify the frequency of a given hazard (death, injury, pollution, …) around the considered plant. In order to do so, all the causes leading to a central event (fire, explosion, leak of toxic and/or flammable product) must be identified.
Then, different accident scenarios are issued from these central events, from the implemented safety measures and from meteorological data. The consequences of each scenario are then assessed as a function of the distance from the release point. The numerical risk for each location around the plan is computed from the frequencies and consequences of all scenario.
QRA studies are typically required for production and processing facilities, high-pressure pipelines, and storage and importation sites.
By performing a QRA, hazards can be identified, and risks at facilities & sites can be quantified. This will prevent major accidents and limit the consequences to the people and the vicinity.
QRA may also be a requirement of applicable legislation or internal corporate decision to show that risks are identified and controlled to an acceptable level. The criteria for risk acceptability may be defined by local regulations or the company.
In many countries, QRA has been deemed mandatory by regulators and authorities to perform QRA as part of legal requirement. For example, QRA is set as a requirement by the following authorities in Singapore:
To help you identify risks and appropriate mitigation measures at your facilities, TÜV SÜD’s experts will cover all the key aspects of QRA over a complimentary webinar. Webinar details as follows:

We strongly recommend that you undertake QRA, to identify hazards and quantify the risks at your facilities and sites.
A comprehensive QRA session with TÜV SÜD will help answer the questions and challenges you have on determining and quantifying risks, enabling you to avert emerging problems and find suitable solutions for existing issues.
We are participating in the Abu Dhabi International Petroleum Exhibition & Conference (ADIPEC) from 11th - 14th November 2019. See you at the TÜV SÜD Booth no. 13455 @ German Pavilion, Abu Dhabi National Exhibition Center (ADNEC) - Hall 13!
