Quantitative Risk Assessment

A Quantitative Risk Assessment (QRA) involves the detailed estimation of the expected incident frequency and consequences of potential accidents associated with a facility or operation. A QRA is an increasingly preferred method of hazard evaluation based on numerical estimation and an invaluable method for making informed risk-based process safety planning decisions, as well as being fundamental to any facility siting decision-making. This analysis enables a detailed understanding of process risks, and where those risks arise from.

ioMosaic has a proven track record of performing quality QRAs. Our professionals have performed assessments globally 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. The ioMosaic team can help you make risk-based decisions with confidence.
