中文摘要：
锚泊阻尼对深水浮式平台的运动响应具有重要贡献。利用单根锚泊线由于上部浮体运动而产生的能量耗散原理计算锚泊阻尼。分别采用准静定计算方法和非线性动力有限元时域分析方法,针对三种具有相似静恢复力刚度,但不同类型的锚泊系统：悬链式、张紧式和半张紧式,对其锚泊阻尼贡献进行比较计算。该结果给出了不同锚泊阻尼计算方法的适用范围,并对不同锚泊方式的阻尼贡献进行了总结。
英文摘要：
Mooring damping provides important contribution to the motion response of deepwater floating platform. The dissipated energy by a mooring line from the floating platform as a result of its oscillation is applied to calculate the mooring-induced damping. The quasi-static method and nonlinear dynamic finite element in time domain method are introduced, respectively. Three types of mooring systems, which are catenary, semi-taut, and taut, have the similar static restoring force characteristics. The calculations on damping contribution of the three mooring types are compared. The results give the scope application of different calculation methods on mooring damping, and summarize the damping contribution of different mooring types.
