摘要

The state-of-the-art was determined for (1) rapid shutdown of failed pipeling systems,and (2) limiting of pressure to prevent failure. Liquid pipelines,gas transmission lines and gas distribution systems were studied. Information was obtained from a comprehensive questionnaire survey of the industry, a literature search,and other sources. The effectiveness of rapid shutdown in reducing accident effects was determined from analysis of historical accident data and analysis of the sequence of events between failure and shutdown. Costs of implementing rapid shutdown and resulting benefits were estimated. Feasibility of a liquid spillage limitation,and relative risks in rapid shutdown vs. continued operation of a failed gas distribution facility were investigated. For systems studied,results indicate that rapid shutdown does reduce accident effects. Rapid shutdown equipment which is technically and economically feasible is identified.
