摘要
参考立管陡S布置的相关文献,结合相关的试验研究,确定了顶部悬挂角、中水浮拱体积和位置为主要设计参数。利用大型水动力软件Orca Flex建立了深水柔性立管陡S布置的模型,并对深水柔性立管的响应进行了非线性时域分析,研究柔性立管的初始形状、曲率和张力对不同总体布置参数的敏感性及变化规律,为深水柔性立管布置设计提供一定的参考。
Based on the relevant papers of Steep S configuration of riser,combined with relevant experimental study,its top hang of angle,volume and position of mid water arch were chosen as the parameters of the configuration. The model of Steep S configuration of deepwater flexible riser has been established by the Orca Flex.Nonlinear time domain analysis of response for deepwater flexible riser were taken on the basis of the model.The sensitivity and the variation rules of the initial shape,curvature and tension of the flexible riser were studied under different conditions,which provides a certain reference for configuration design of deepwater flexible riser.
