“…The wave and whipping bending moments have been correlated by a probabilistic load combination method [38]. The influence of the correlations was further investigated by a comparison of numerical and There are other methods and formulations that have been investigated by Wang and Guedes Soares [33][34][35][36][37] and Wang et al [28], which consider the effect of the local structure's deformation on the slamming force on the bow, which could be considered in future implementations. The wave and whipping bending moments have been correlated by a probabilistic load combination method [38].…”

The hydroelastic behaviour of a river-sea-going ship hull is analysed experimentally and numerically. A segmented ship model connected by a steel backbone is tested in regular waves, and its high-frequency vibrations such as springing and whipping responses are identified. The hydroelastic response of the ship is numerically calculated using a hydroelastic time domain method based on strip theory, which is extended to include an improved model of the slamming load. The slamming forces in the bow section are determined using the Modified Longvinovich Model (MLM) instead of the Von Karman model. The vertical motions and wave-induced loads are calculated and compared with the experimental results. The response amplitude operators of the vertical loads and the high-order harmonics are analysed under different speeds, showing good agreement with the experiments. The slamming loads on the bow section of a river-to-sea ship are predicted utilizing the MLM model and compared with the Arbitrary Lagrangian Eulerian algorithm by LS-DYNA and with the measured results.

“…A significant motion of the vessel and intense free water surface have to be calculated accurately to obtain reliable slamming load. Although studies, which predicted the slamming pressure were conducted often under irregular wave conditions in full scale [14,15], this is deemed impractical to be applied to the design phase considering the calculation time for simulation. Therefore, simplifications of irregular waves to regular waves under head sea conditions, and simplified interpretations using incident waves have become common [16].…”

A container ship has large flare on the bow flare region to accommodate more container recently. This flare region experiences the impact pressure due to slamming phenomenon under rough sea conditions. The impact pressure is transferred to the hull structure and the impact pressure causes structural damage. A strength assessment of the bow region is evaluated based on the empirical formulas according to various classifications. In this study, the numerical simulations were performed to compare with empirical method, and predict the bow flare slamming pressure on the container ship. It is found that the bow flare slamming pressure generated up to 625kPa near 0.975 station and the bow flare slamming pressure obtained from the formulas of the CSR and ABS tend to be similar to the CFD results.
