摘要
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,采用Morison方程和绕射理论相结合的方法,运用DNV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。
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 of Morison equation and diffraetion theory, the hydrodynamic analysis for semi-submersible platform is carried out by a combination method of Morison equation and diffraction theory. The SESAMsoftware is used for water depth effect about the hydrodynamic analysis of semi-submersible platform,
