This paresentation presents a rational quasi-dynamic response approach for the evaluation of global loads of passenger vessels. The method couples wave-induced hydrodynamic pressures with a rigid hull idealization performed with ANSYS AQWA and ANSYS SpaceClaim. The CAD structural model of a typical cruise ship was produced using CADMATIC Hull with basic design accuracy. NAPA software was used for evaluating the still water bending moment. Consequently, the 3D diffraction/radiation panel code ANSYS AQWA was used to define the wave pressures acting on the hull and loads were mapped on the hull surface and transferred to the ANSYS FEM solver for hydro-structure coupling.
Comparisons against Class Society Rule wave bending moment and shear forces amidships demonstrates that the direct evaluation of the wave bending moment and shear force envelopes along the hull girder may be a preferred approach in terms of assuring global structural strength and optimizing total steel weight.
