| 摘 要： | 栈桥是连接海上油气田两个或多个平台间油气水管线、电控线缆和人员通行的通道.平台间在风、波浪、船舶靠泊等荷载作用下会发生相对运动,通过栈桥的管道会承受平台间相对运动产生的位移荷载,管道应力水平是否满足规范要求在应力分析中需要重点考虑.应用CAESAR II软件,结合旅大27-2/32-2油田开发项目栈桥管道柔性计算实例,介绍了栈桥管道应力分析的模拟方法,并根据计算结果对管道布置提出建议和进行优化,为以后栈桥管道的设计提供计算方法和参考.

| Abstract: | The cross-bridge piping connecting two offshore platforms may suffer displacement loads,which induced by relative movement between two platforms due to wave motion,ship berth and so on.In stress analysis,it is important whether the calculated stress exceeds the allowable stress.In this paper,taking the cross-bridge piping flexibility analysis in LD27-2/32-2 oil development project as an example,stress analysis methods of cross-bridge piping with the stress analysis software of CAESARII are introduced in det... |
