| 摘 要： | 应用数值模拟与模型试验相结合的方法研究半潜式生产平台系泊状态下的耦合动力特性。建立耦合分析模型,时域内计算求解平台的动力响应,选取缩尺比为1∶60,采用等效截断模型方法对数值模拟结果进行验证。通过对比模型试验与数值模拟结果发现:等效截断系泊系统可以较好地模拟平台的位移响应,但在系泊张力方面却差异较大,此外极端海况下平台的甲板上浪问题也必须得到充分重视。

| Abstract: | The characteristics of coupled dynamic response for the moored semi submerged production platforms are studied by the model experimental approach and the numerical simulation method in this paper. The coupled analysis models are established and the dynamic responses are obtained in time domain.An equivalent truncated model test is adopted, with the model scale 1:60, and the 6 DOF motion of the two platforms and the mooring line tensions are recorded in order to validate the numerical results.By comparing the full depth numerical results, it is concluded that the dynamic response of the platform can be modeled quite well, but the difference of the mooring line tension is significant. In addition, enough attention should be paid to the green water problem in rough sea. |
