R2A Method



The R2A method is the software process by which relevant intellectual property is captured either in Excel® or SuperCard®. This is typically used for bottom up processes. Six Excel templates are available for download under Publications.

The other primary platform used by R2A is SuperCard® which utilises Object Oriented Programming Models. These are a visually based data capture, modelling and risk analysis tool. Technical projects are R2A based projects developed to use as an analysis tool for specific problems. Current projects include:

  • ePlans (emergency plans). This tool develops emergency evacuation plans to satisfy common law requirements Plans are posted in the correct orientation so that non technical readers can orientate themselves intuitively.

  • Explosions. A consequence calculator that models explosion impact distances for a particular chemical product.

  • Jet Fires. Designed to calculate the dimensions of a flame resulting from the rapture of a pipeline containing flammable material.

  • Pool Fire. This model provides an approximation of the physical characteristics and effects of a user-specified pool fire.

  • Profiling. This is a workshop documentation tool which can sustain images, video, sound and animations in addition to plotting and navigating abilities. The calculator can be used to complete threat based vulnerability assessments, zonal vulnerability assessment, issues profiling, value adding exercises, HazOp studies, Failure Modes Effects and Criticality Analysis (FMECA), Safety Integrity Level (SIL) assessments and many other risk profiling activities.

  • Threat Barrier Modelling. This tool is used to map timelines of threats and consequence whilst incorporating the legal loss of control point.


    • All computational models implemented in the R2A Method are initially validated and verified in-house. Major consequence models are also validated by external third parties.
