Transmission pipelines carrying natural gas are not typically within secure industrial sites and may cross through both rural and heavily populated areas. Failure of the pipeline can lead to various outcomes, some of which can pose a significant threat of damage to people and properties in the immediate vicinity of the failure location. Statistical data of accidents in Europe showed that the rupture of a pipeline can be caused by mechanical fracture, ex-ternal mechanical interference by third party and earthquake. Statistical data also showed an overall failure rate of 0.575 per 1000 km.year. In the event of rupture, a gas cloud would form and its size depends on the geometrical parameters of the pipeline and of the rupture. Estimation of the gas cloud size will be needed therefore to analyse this kind of accindents. This study is focused to propose a simple and reliable approach to sizing the ground area potentially affected by the failure of a high-pressure pipeline carrying natural gas.

Abstract
Transmission pipelines carrying natural gas are not typically within secure industrial sites and may cross through both rural and heavily populated areas. Failure of the pipeline can lead to various outcomes, some of which can pose a significant threat of damage to people and properties in the immediate vicinity of the failure location. Statistical data of accidents in Europe showed that the rupture of a pipeline can be caused by mechanical fracture, ex-ternal mechanical interference by third party and earthquake. Statistical data also showed an overall failure rate of 0.575 per 1000 km.year. In the event of rupture, a gas cloud would form and its size depends on the geometrical parameters of the pipeline and of the rupture. Estimation of the gas cloud size will be needed therefore to analyse this kind of accindents. This study is focused to propose a simple and reliable approach to sizing the ground area potentially affected by the failure of a high-pressure pipeline carrying natural gas.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
