| 摘 要： | 本文根据有条件的建模方法（CMA）和一次逆可靠度方法(IFORM)，运用Matlab编程计算确定百年一遇波高-周期的等概率曲线，设计了一组百年一遇波浪海况。根据Morison方程与绕射理论计算海洋平台波浪载荷的各自特点，本文采用Morison方程和绕射理论相结合的方法，运用挪威船级社研发的SESAM程序，就水深对半潜式海洋平台水动力性能和波浪载荷的影响进行了分析。某半潜式海洋平台计算分析水深对平台的运动响应、气隙、波浪二阶平均漂移力和纵向剪切力等六个波浪载荷的影响。

| Abstract: | The Conditional Modeling Approach (CMA) and the inverse reliability method (IFORM) are used for calculating the 100-year-return environmental contour about wave height and period by Matlab software in this paper. A set of sea states conditions are designed, which will be used for hydrodynamic analysis and short term response. According to the characteristics for Morison equation and diffraction theory, the hydrodynamic analysis for semi-submersible platform is carried out by a combination method of Morison equation and diffraction theory. The SESAM software is used for water depth effect about the hydrodynamic analysis of semi-submersible platform. |
