Wave Impact Excitation on Ship Type Offshore Structures in Steep Fronted Waves

Wave impacts in steep fronted waves can induce extremely large impact pressures on the hull of moored ship-type offshore structures. As part of the SAFE-FLOW Joint Industry Project these loads were investigated with a dedicated series of model tests. Based on the results a prediction method is developed, which can be applied in the early design of the bow structure. The paper first summarizes the test philosophy and the developed prediction method. Then the practical design considerations related to bow slamming are discussed in a study focusing on the new DP-FPSO concept for a single environment.
