| 摘 要： | 对于深水系泊钻井系统而言,移动式海洋钻井装置与细长结构(系缆、钻井隔水管)之间的耦合效应在预测浮体运动及钻井隔水管响应时起决定性作用.文中建立了深水系泊钻井系统的全耦合有限元模型,考虑波频与低频环境载荷,对系统进行了非线性时域分析.分析表明,由低频浮体运动激励的低频隔水管动态响应可对深水钻井隔水管设计产生重要影响.常规方法将低频浮体运动作为准静态效应考虑,对于连接在锚泊钻井装置上的深水钻井隔水管而言是不精确的.

| Abstract: | For a deepwater moored drilling system, the coupling effects between the mobile offshore drilling unit (MODU) and the slender structures (mooring lines and drilling riser) are of primary importance in prediction of the floater motions as well as the drilling riser response.In this paper,a fully coupled finite element (FE) model of the moored drilling system was established and used in the following non-linear time-domain analysis considering irregular wave frequency (WF) and low frequency (LF) environmental... |
