This work aimed to analyse, using the ﬁnite element method, the inﬂuence of dynamic-induced dumped hull oscillations, named “whipping” on structure strength. The presented results are part of the project carried out in the Research and Development Department of the Polish Register of Shipping. The review of existing techniques to determine the ship hull structural response due to the hydrodynamic forces is outlined. Additionally, the necessity to consider the dynamic hull vibrations in assessing the hull girder strength has been addressed. A series of models were prepared to investigate the effect of hull stiffness, added mass and forces modelling on the received global bending moment values. The bow flare slamming loading was determined using the simplified method. The obtained results are discussed, and future works are outlined.
