【Abstract】 By using direct calculation method, the global strength of the wind turbine installation vessel is evaluated in the transit condition. Based on the three-dimensional potential flow theory, long-term forecast of the vertical wave bending moment are carried out, and the corresponding designed wave parameters are determined. Based on the finite element model of the hull and lattice legs, the gravity, hydrostatic pressure, the hydrodynamic loads induced by the wave, inertia force on the legs and hull are considered, and the direct calculated method is used to evaluate the global strength of the hull and legs. The proposed method and results are effective for strength assessment of wind turbine installation vessel, and it provide a reference for the global response analysis and the optimization design of the hull structure of this kind.更多还原
