针对目前输气站场设备风险评价方法仅以单个设备为评价对象,并未考虑设备间相互影响的特点,提出将多米诺效应分析引入输气站场设备风险评价当中,再结合RBI (基于风险检测方法)对输气站场设备进行定量风险评价。首先,计算所评价设备的失效概率与危险指数,得到设备固有风险;然后对设备的多米诺效应风险进行计算;最后,得到设备总风险。实例分析表明,考虑多米诺效应风险后,站场单个设备的风险要明显增大。
針對目前輸氣站場設備風險評價方法僅以單箇設備為評價對象,併未攷慮設備間相互影響的特點,提齣將多米諾效應分析引入輸氣站場設備風險評價噹中,再結閤RBI (基于風險檢測方法)對輸氣站場設備進行定量風險評價。首先,計算所評價設備的失效概率與危險指數,得到設備固有風險;然後對設備的多米諾效應風險進行計算;最後,得到設備總風險。實例分析錶明,攷慮多米諾效應風險後,站場單箇設備的風險要明顯增大。

The current assessment methods focus on single facility and ignore influences between facilities , so a method of quantitative assessment with domino effect analysis and RBI ( risk-based inspection technology ) was pro-posed to assess facilities risks of gas transmission station .Firstly, the inherent risk of the facility was obtained with failure probability and hazard index calculated .Then, the risk of domino effect was ascertained .At last, the total risk of facility was calculated .Example analysis verified that the risk of single facility in gas transmission increases significantly when taking domino effect risk into account .
