چکیده انگلیسی
In the hydrodynamic study of Semi-submersibles, the wave pressure distribution on the wetted surface is critical input for structure analysis. Based on wave radiation and diffraction theory, a higher-order boundary element method (HOBEM) was applied to calculate the wave pressure distribution for a semi-submersible under specified wave direction and frequency. An integral system containing the FEM modeling of the semi-submersible, numerical calculation of hydrodynamic motion coefficients and data extraction and export for BEM analysis was established in the current study. A newly developed multiple and double nodes relocation method coupled with FEM-BEM model transformation is applied to remove the singularities along the sharp edges and corners of the semi-submersible. The numerical results confirm that the above algorithm significantly improves the numerical accuracy of wave pressure analysis for the semi-submersible.
