Fault Tree Analysis of Oil Refinery

CAPE-SAFE can be used to conduct fault tree analysis, as a call is initiated from the design environment. The fault tree analysis will be implemented automatically using the plant design model. The resulted fault tree ean be viewed as in figure 9-12. 

In this figure, the seleeted initial event can be selected from the design environment, or ean be extracted by applying automated HAZOP, which highlight list of top events that may eause hazard. In this case, product flow rate (F ) is low has been selected as the initial event. The result of the fault tree analysis as generated by CARA shows total of six cut sets up to order four. The results of the fault tree are fed back to HE Results database as associated with each plant physical object. The relationships among proeess variable, fault, component, and failure are used in the automation of generating the fault tree results. The minimum eut sets represents the different seenarios for the occurrence of the top event (output product flow rate is low).
