We discuss structural response analysis of vessels subjected to hydrodynamic loads. The response analyses are performed in order to assess vessel strength either through quasi-static ultimate strength analyses (ULS) or stochastic fatigue analyses (FLS). We focus on consistency in modeling with emphasis on accurate load transfer between the fluid- and structure domains. In wave analysis the dynamic pressure- and inertia forces are generated through a linear ship, where the vessel is treated as a rigid body. The calculated pressure forces are distributed on the fluid panel interface while the inertia forces (accelerations) are represented on the rigid body structure. The final strength assessment is carried out on a finite element model (FEM). The FEM interface model and the panel interface model are assumed to be incompatible both in geometry and field representation.
