Calculating the hydrodynamic forces experienced by ships passing through the frozen sea area requires numerical study. In this study, tank experiments conducted under dense brash ices—whose effects were disregarded by earlier calculations—are used to validate the numerical results. As a result, the hydrodynamic force of a single piece of ice was successfully reproduced. In the case of two vertically aligned ices, the effects of ice spacing on the hydrodynamic forces acting on the rear ice were qualitatively reproduced. One of the ices in the dense brash ices experienced inconsistent hydrodynamic forces between experiment and calculation. Different flow fields between them are the primary reason because the relationship between the flow velocity around the ice and the pressure on it made sense in the calculation.
