Abstract:The spectrum of wave loads is reduced by the Airy Wave Theory and the linearized Morison Equation. The model analysis methods and the space frame finite element are used to carry out the responses of offshore structure, including the displacement response and the stress response. The fatigue reliability analysis of structure is based on the structural response analysis in the frequency domain. In the fatigue reliability analysis, supposing the stress is in Rayleigh distribution. And the spectrum of stress is performed by the transfer function of the jacket platform. The results show that the Miner model can be applied to calculate the fatigue reliability of the structure.
