Abstract

The gas pipeline is a central focus of accident-prone, so that events can be various outcomes in different aspects of human, social, financial, political or environmental is. That is why one of the most important activities for the management and risk assessment networks of natural gas pipelines, especially in towns. This is a comprehensive program of quantitative risk assessment for pipelines and gas distribution networks from sensitive areas and densely populated pass, suggests. To this end, the area of network segmentation with appropriate indicators, different possible scenarios of events in relation to gas leaks can be detected by techniques FMEA and ETA and The ultimate consequences of these scenarios and possibilities and different aspects of human, financial and social are earned, for that purpose simulator software-related incidents leakage of toxic substances have been used to obtain human consequences. Using utility theory and safety managers and experts, extracted consequences utility functions and probabilities calculated by the risk categories in relation to each scenario is obtained with the same unit. And thus different parts of the region to be ranked in terms of risk. The model presented as a case study with data collected plenty of Isfahan gas pipeline network and its events, have been described.
