Multi-attribute Analysis of Consequence Severity in Risk Assessment for Natural Gas Pipelines

Multi-Attribute Risk Assessment

Best practice dictates that security requirements be based on risk assessments; however, simplistic risk assessments that result in lists of risks or sets of scenarios do not provide sufficient information to prioritize requirements when faced with resource constraints (e.g., time, money). Multi-attribute risk assessments provide a convenient framework for systematically developing quantitative...

Qualitative Risk Assessment of Gas Pipelines by Using of Indexing System Method in GIS environment

Nowadays the urbanization is developing rapidly, and it leads to growing demand for gas; which resulted in denser pipeline network, by the following increase in the pipeline network congestion, accidents  will become inevitable. So Pipelines are a remarkable source of hazard for their adjacent society. Usually Indexing system method is used for pipe line risk assessment. This method assesses ri...

risk assessment of exposure to gases released by welding processes in iranian natural gas transmission pipelines industry

exposure to welding gases can cause health adverse effects. risk assessment is a useful tool for good assessment of exposed workers. the purpose of this study was to determine the risk levels for exposed welders to welding gases. welders (n=239) were selected from iranian natural gas transmission pipelines industry from four regions in iran including assaluyeh, omidieh, loshan, and borujen. ozo...

Multi objective optimization of the vibration analysis of composite natural gas pipelines in nonlinear thermal and humidity environment under non-uniform magnetic field

The fluid-conveying pipe is a fundamental dynamical problem in the field of fluid– structure interactions. In recent years considerable attention has been given to the lateral vibrations of pipes containing by a moving fluid. In this paper, the vibration analysis of composite natural gas pipeline in the thermal and humidity environment is studied. The effect of the non-uniform magnetic field is...
