چکیده
This paper presents a methodology for quantitative risk analysis for offshore installations, that incorporates both technical and operational conditions. The basic building blocks of the methodology are barrier block diagrams, event trees, fault trees, and influence diagrams. Barrier block diagrams are used to illustrate the event scenarios and the effect of barrier systems on the scenarios. Event trees are used in the quantitative analysis of the scenarios, while fault trees are used to analyze the performance of the different barrier systems. Influence diagram are used to analyze the effect of risk influencing factors on the initiating events in the event trees and the basic events in the fault trees. The aim of the analysis is to reflect installation specific factors both with respect to technical systems, operational conditions as well as human and organizational factors.
