Влияние изменений в структуре ремонтируемых трубопроводных транспортных систем на их стойкость при возникновении аварий

Abstract

Features of functioning of the pipeline transport systems in the conditions of repair, reconstruction or preservation of separate parts are considered. It is shown that the structural changes connected with it create additional risksfor end users of a target product. Transition to a condition of nonserviceability of some set of pipelines is considered as process of the progressing damage which development leads to disconnection from a source at first parts, and then and all consumers. The ability of a system to resist to development of the progressing damage is characterized by the firmness indicator representing an average share of pipelines which accidental transition to a stateof nonserviceability brings to disconnection from a source of all consumers. It is offered to provide the required level of firmness of the recovered system by the choice and implementation of the rational scheme of shutdownof the repaired pipelines. The algorithm of the choice of rational schemes of shutdown of pipelines in dependence of conditions of preparation and implementation of repair is formulated.
