Abstract According to the complicated characteristic of the ship fin stabilizer reinforced structural design and loads, a CAD/CAE integrated design and analysis method was presented to do three-dimensional structure design, hydro-dynamic analysis and structure property assessment of fin stabilizer reinforced structure. In this research, the multi-point constraint method is adopted to realize the load transfer between two kinds of discordant elements, which simulate fin stabilizer reinforced structure and fin stabilizer foundation, the ship motion response and hydrodynamic pressure are obtained by the free surface Green function method and the three dimensional linear potential flow theory. The key techniques discussed in this research provide a new technical approach for fin stabilizer reinforced structural design and analysis.
