from the data, revealing a striking resemblance in trend between the results obtained from the hydrodynamic impact simulation and the static simulation. Notably, the full shell modelling methodology consistently yields the highest stress values, followed closely by the concurrent multi-scale and multi-stage multi-scale modelling approaches. In contrast, the full solid modelling technique consistently produces the lowest stress results among the investigated methods. The observation on Figure 12 reveals an important fact that the Full Shell method manifests the highest stress levels at the front bulkhead of the float structure during hydrodynamic impact simulation. Conversely, the Full Solid model exhibits the lowest stress magnitudes, showcasing a notable disparity. Intriguingly, both the multi-stage multi-scale
