对于液化天然气储罐,关注的重点往往是安全性与经济考量之间的怎样取得一个平衡,就大陆的石化工程而言,依据怎样的标准既满足社会对工程安全的期待值,又符合液化天然气储罐的结构特点和场地特征,一直是个重要的课题。重点介绍了对于液化天然气储罐这类结构的在设计中的运行基准地震水平(OBE)和安全停机地震水平(SSE)的确定。以曹妃店岛的LNG项目为例,介绍了液化天然气储罐所采用的地震设计反应谱。
In the case of liquefied natural gas storage tanks, the focus of attention is often on how to strike a balance between safety and economic considerations. As far as the petrochemical projects in mainland China are concerned, what criteria are met to meet the expectations of society for project safety and to meet the requirements of liquefied natural gas The structural features and site characteristics of storage tanks have always been an important issue. Highlights the OBD and SSE determination of design of such structures for LNG storage tanks. Taking the LNG project of Cao Fei Dian Island as an example, the seismic design response spectrum used in LNG storage tank is introduced.
