中文摘要：

张力腿平台（TLP）是一种垂直系泊的半顺应半刚度式平台,预报平台的运动响应及锚泊系统的张力是张力腿平台结构设计的重要基础。应用挪威船级社SESAM软件在频域和时域内研究了张力腿平台在随机波浪中的非线性运动响应及系泊系统特性,并在试验室中通过缩尺比为1∶40的模型进行了试验验证。在试验验证的基础上,将仅考虑浪与考虑浪、流联合作用下的张力腿的张力平均值、幅值及标准差作了对比。结果表明,在较低海况时,考虑浪和流时的张力腿与不考虑流的情况变化不大;在较大海况时,流的影响不可忽略,考虑流的张力腿变化幅度要略大于不考虑流的情况。

英文摘要：

Tension Leg Platform（TLP） is a vertically moored semi compliant and semi stiff offshore structure.Predicting the dynamical response and characteristics of mooring system is the important base of the design of tension leg platform.The nonlinear dynamic response and characteristics of mooring system of TLP are studied in frequency domain and time domain under stochastic waves using the software of SESAM developed by the DNV classification society.The TLP model scale of the target structure in the State Key Laboratory of Ocean Engineering of Shanghai Jiao Tong University is selected as 1/40.The results of experiment are compared with the numerical simulations.The amplitude value,average value and standard deviation considering the influence of the current are compared with those not considering the current based on the verification of the experiment.
