The SDG-HAZOP(Signed Directed Graph,Hazard and Operability Analysis) is a qualitative safety assessment method,which is comprehensive,systematic and complete.However the result is tedious and large.Fault tree analysis(FTA) is a logical and diagrammatic method,which is proved to be a useful quantitative analysis tool to evaluate the safety and reliability of complex systems.So a FTA based on SDG-HAZOP quantitative method was proposed in this paper.Firstly,the SDG-HAZOP and the FTA were established on the background of polypropylene production devices in the Sinopec Wuhan Branch.Secondly,the probability of top event was calculated by reliable data from the probability of basic events.Finally,the targeted measures were proposed to prevent fatal potential dangerous situations by probability calculation.
The SDG-HAZOP (Signed Directed Graph, Hazard and Operability Analysis) is a qualitative safety assessment method, which is comprehensive, systematic and complete. How the result is tedious and large. Fault tree analysis (FTA) is a logical and diagrammatic method, which is proved to be a useful quantitative analysis tool to evaluate the safety and reliability of complex systems. So a FTA based on SDG-HAZOP quantitative method was proposed in this paper. Firstly, the SDG-HAZOP and the FTA were established on the background of polypropylene production devices in the Sinopec Wuhan Branch. Second of the probability of top event was calculated by reliable data from the probability of basic events .Finally, the targeted measures were proposed to prevent fatal potential dangerous situations by probability calculation.
