- W2474496772 abstract "以某深水天然气开发的中心处理平台外输天然气管道为研究对象，利用OLGA®软件对不同水深，不同孔径和不同外输流量条件下的泄漏进行数值模拟。数值模拟共完成了32个泄漏场景，得到了4个水深，3种泄漏孔径和2种外输流量下的初始泄漏速率、泄漏持续时间和泄漏总质量，研究中考虑了海管高程，立管容量，水下截断阀，水下泄漏时深水的静水压力，泄漏的探测与关断，陆岸终端放空的影响。研究结果可以作为进一步风险分析和应急准备分析的输入，同时可以作为应急响应时事故处理的重要技术支撑。 This paper presents the numerical simulation results for a subsea gas pipeline release, which was designed to expert high pressure nature gas from Deepwater offshore platform to the onshore re-ceive terminal. 32 leak scenarios were simulated using OLGA® and concluded the initial leak rate, leak duration and released mass weight in 4 water depths, 3 hole sizes and 2 flow rates. The re-search assesses the influence of subsea pipeline’s elevation, riser inventory, subsea safety isolation valve, external hydraulic pressure, leak detection, emergency shutdown and blowdown from onshore terminal. The research results could be used as critical input for the further risk analysis and emergency preparedness analysis meanwhile could be the important technical support to emergency response and mitigation actions." @default.
