| 摘 要： | 作为深水油气开发中的一种先进立管形式,自由站立的混合立管得到了越来越多的关注。文章采用一可高效处理几何非线性的有限元程序对一典型混合立管进行了参数分析,研究了在海流的作用下浮箱的直径、长度、潜水深度及柔性管的长度等参数对立管静力平衡位形的影响。在浮体横荡和规则波作用下的动力分析则证实了混合立管的准静力响应特性。当浮箱置于水下一定深度时,由海面浮体运动和波浪作用引发的浮箱运动很小,以至于它对柔性管动力响应分析的影响可以忽略。

| Abstract: | Free standing hybrid riser,as an enabling technology for deep field developments,has acquired increasing attention worldwide.In this paper,a parametric study of a single line hybrid riser is conducted,using an in-house FEM code which can handle geometric nonlinearity efficiently,to examine its global response behavior.The effects of varying parameters-buoyancy tank depth,jumper length,tank diameter and tank length,on hybrid riser's static equilibrium profile are investigated under the action of current.Dyna... |
