A newly developed finite volume method was applied to ship slamming. The computational method accounts for arbitrary free surface deformations and uses unstructured grids for the discretization of the domain. A linear panel method was used to predict motions of a modern 2400 TEU container ship. Resulting relative velocities at the ship’s Keel were used to estimate the maximum vertical re-entry velocities at the bow in North Atlantic wave conditions. Water entry of three bow in North Atlantic wave conditions. Water entry of three bow sections was numerically simulated to determine pressures at the bow flare. Prescribed vertical velocity histories significantly affected the determination of realistic pressure levels.
