Here we will explore the basic functions of the system. Mostly we will identify the main elements and options for the calculation of the risk. The Riskan organizes information in the form of a tree of objects, to the left side, where each object contains information and commands.

The central area of the Riskan window contains the results or information about the selected object. When you start Riskan it will show an empty map. The results area can be viewed in a number of modes, depending on the selected object. To change the view mode, use the tabs below the results area.

Main elements

Before we can proceed in the elaborating a risk analysis, is recommended that the user gets familiar with the main elements of Riskan.

  • Object tree - Where all elements of the analysis are shown and can be selected
  • Results area - Where Riskan will presents information and simulation results
  • Menu - With options and functions

Risk analysis script

To execute a risk analysis, you must execute a number of tasks. Of course, depending in which type of analysis you are performing, some of these tasks are not necessary or other tasks may be needed. We will show the tasks for the quantitative risk analysis.

Before using Riskan, you have to select the accidental hypothesis for your target plant using PHA, HAZOP or FMEA techniques. You must also, estimate the expected frequency of occurrence of these hypothesis, using reliability engineering techniques. These are all input data for Riskan and are not calculated within the program.

After you have determined the accidental hypothesis and their expected frequency of occurrence, you can start the analysis in Riskan in these steps:

After you are familiar to the basic operation, you can proceed to the advanced functions of Riskan, which may be helpful in a number of situations.
