中文摘要:川氣東送管道是我國東西部地區的天然氣管道大動脈,如何針對不同的管線、設備失效規律和特點開展風險量化評價是實施站場完整性管理的基礎和關鍵。針對川氣東送管道典型輸氣站場特點,制定了由風險預評估和檢測、RBI、SIL與RCM分析組成的風險量化評價流程。根據站場管道流場模擬結果確定了站場重點檢測對象和位置,結合川氣東送管道站場的HSE管理目標提出了合理的可接受風險準則。利用建立的風險量化評價流程和方法,對普光首站的278個設備/管道項進行了風險量化評價,合理制定的風險控制與檢驗計劃可有效防止失效事故的發生,從而有效提高川氣東送管道站場的安全運行能力和完整性管理水平。
英文摘要:Sichuan-East Gas Pipeline is one of the most important pipelines in China's eastern and western regions. Conducting quantitative risk assessment according to different failure laws and characteristics of pipelines and equipment is the basis and key to implement integrity management on gas transportation stations. Analyzed are characteristics of typical gas transportation stations in Sichuan-East Gas Pipeline, developed is quantitative risk assessment process including risk pre-assessment and inspection, RBI, SIL and RCM analysis, determined are key inspected objects and their locations in gas transportation stations on the basis of in-station pipeline flow field simulation results and proposed is an acceptable risk criterion in combination with HSE management objectives of gas transportation stations in this pipeline. Adopted are the quantitative risk assessment process and method established already to conduct quantitative risk assessment on 278 items of equipment and pipelines in Puguang Gas Station and developed are reasonable risk control and inspection plans, which can effectively prevent failure of equipment and pipelines, enhance safety operation capacity of gas transportation stations in Sichuan-East Gas Pipeline and improve integrity management on these stations.
