When performing a QRA for a large chemical facility we have observed that a lot of our customers end up having a very large project file containing hundreds (or even thousands) of scenarios that account for all the different sections of the establishment of interest. This not only leads to very large and compute-intensive project files but also makes it increasingly difficult to interpret specific results and even tends to obscure the overview of what belongs to what section.
As of version 11.3.0, RISKCURVES includes functionality that will make the QRA process for these large projects more efficient by being able to accumulate multiple separate projects in just minutes.
This will not only remove the nuisance of working with these very large project files and their associated calculation and loading times but also allow (multiple) users to do the calculations on sections of the total project in parallel, hence, greatly reducing the turnaround of the total project.
These benefits are achieved by the possibility to import only the calculated risk results of a project, instead of the complete project definition. Recalculation is no longer necessary, and the accumulation of these imported calculations is then a matter of minutes.
Before the release of version 11.3.0, we used to advise to split up the QRA into different “Calculation sets” corresponding to different sections of the facility, such as separation section, reformer, cooling, power generation, etc. or to evaluate possible changes in or around the facility, such as an increase of population. With this new functionality, the study can be divided into partial projects, each of them containing a comprehensible list of equipment and distinct units, which makes the QRA-making process even easier.
Imported calculation sets can contain Individual Risk, Societal Risk and Consequence Risk results, which can be cumulated with other parts of the study by means of a Cumulation Set.
Importing project results is just a few clicks and is all handled by an Import Wizard. This wizard will check if the imported results meet the requirements and warn if certain necessary conditions are not met. After importing, the imported results will be shown in the project tree and can be incorporated into a cumulation set like any other equipment, scenario or calculation set in the project.
