摘　　要：随着海洋石油向深水领域的拓展,SPAR平台以其诸多优点逐渐成为海上油气生产的主流设施。主要研究SPAR与系泊系统间的耦合响应问题,在讨论了浮体在波浪中运动求解方法之后,阐述了如何利用非线性有限元技术对系泊缆索和立管进行动力分析和张力计算,以及浮体与系泊系统耦合计算的相关理论,对浮体和系泊系统耦合计算模型进行了描述。通过对某SPAR进行系泊系统耦合计算和对计算结果的讨论,证明了深海SPAR系泊系统耦合计算的正确性。With the development of deepwater oilfields, SPAR platform is being used more widely according to its many advantages and becomes very competitive floater concept in ocean engineering. The coupled analysis of SPAR and its mooring and riser system is mainly studied. Hydrodynamics of a floater are discussed, the nonlinear finite element method to calculate the tension of the mooring lines and risers is discussed afterward. The coupled analysis theory of the hull motions and the mooring system is described and a case study is performed to indicate the necessary of coupled analysis in deepwater mooring system analysis.
