Dynamic wave pressure distributions of semi-submersible
摘要
Abstract
Based on wave radiation and diffraction theory, in this paper, we apply a higher⁃order boundary element method ( HOBEM) and consider symmetry to calculate the wave pressure distributions of Semi⁃submersibles for def⁃inite wave directions and frequencies. First, we used an integral system containing an FEM Semi⁃submersible mod⁃el, calculated the hydrodynamic motion coefficients, and exported the data for BEM analysis. We then applied a newly developed multiple and double node relocation method coupled with the FEM/BEM data transformation along the complicated sharp edges and corners of a Semi⁃submersible. This algorithm significantly improves the accuracy of wave pressure analysis and the numerical stability of high⁃frequency wave calculations.关键词
