| Abstract: | The radiation/diffraction theory is used to calculate wave load acting on semisubmersible platform, and wave load was transferred to the FEA model of the platform, the response of the global structure is calculated. The fine FEA model of typical joint is made, the load boundary condition is based upon the result of global FEA, the hotspot stress transfer function are calculated by considering hydrodynamic load and gravity load. With Spectral- based fatigue analysis method and based on Miner theory to evaluate the fatigue life of the typical joint in South China Sea condition. |
