WebHydrostatic restoring The calculation of the hydrostatic restoring for the seakeeping part does not change and we can directly use the expressions given in [2, 3]. However, it should be noted that, when calculating the part of the restoring which is related to the structural mass i.e. Cm ij, the volume integral should exclude the mass of Web12 mrt. 2024 · The current methods of approximating the roll restoring moment are based on hydrostatic calculations. These methods fail to consider the dynamic conditions and variation of upward buoyancy and wave location with respect to the model.
