6. Example of a quantified bow tie
6.1 Case study presentation
To illustrate the quantified bow-tie methodology, a simplified case is studied with the dreaded event "rupture of an unloading arm of a liquefied gas wagon". The assumptions are as follows:
liquefied gas is not unloaded in a closed enclosure;
the unloading station is located in an area that could potentially be affected by domino effects (explosion on a neighboring unit).
This case study is intended to illustrate the various stages of the method:
the creation of the fault tree, which enables an analysis of the minimum cuts in the tree and an assessment of the frequency of occurrence of the feared...
