Risk Assessment System for Oil and Gas Pipelines
 Laid in One Ditch Based on Quantitative Risk
 Analysis

In view of the vegetation reduction caused by the continuous construction of oil and gaspipelines, the pipelines have been designed to be laid in one ditch to reduce land occupation.However, owing to the small spacing between the pipelines, the fault correlation between pipelineshas been proven to increase the potential hazard of adjacent pipelines and routing environments.The neglect of failure correlation in existing risk assessment methods...
