Quantitative Risk Analysis Defined
A quantitative risk analysis (QRA) involves the detailed estimation of the expected frequency and consequences of potential accidents associated with a facility or operation.
Value of QRA
A QRA is an invaluable method for making informed risk-based process safety planning decisions, as well as being fundamental to any facility siting decision-making. It enables a detailed understanding of process risks, and where those risks arise from. In conducting a QRA, these risks can be better managed and mitigated.
ioMosaic has a proven track record of performing QRAs. Our professionals have performed assessments
on a wide range of facilities, such as refineries, chemical plants, pharmaceutical plants, tar sands, crude oil
refineries, LNG facilities, and rail and marine transportation terminals. Let ioMosaic help you make risk-based
decisions with confidence.
ioMosaic uses the state-of-the-art software tool, Process Safety Office™ component SuperChems™, to conduct QRAs. SuperChems has all the functionality necessary to conduct a QRA and can be used for calculating risk for fixed facilities, pipelines or transportation routes. ioMosaic understands that QRAs consist of two principal steps: preparation and implementation. SuperChems can help you with both steps:
- Define meteorological and topographical data in SuperChems
- Visually define population data in SuperChems
- Visually define Ignition data in SuperChems
- Define your risk tolerability criteria
- Generate failure scenarios in SuperChems
- Generate results in SuperChems (graphical and tabular)
- Toxic effects
- Radiation effects
- Explosion effects
- Individual risk
- Societal risk
- Analysis of results
- Risk-ranking of scenarios
- Filtering of results
- What-If scenarios
