The research about icebreaker and other polar ships has attracting much attention in the field
of ship and ocean engineering. In this context, it’s essential to predict the resistance of ship in
the Arctic region accurately. The recent research mostly focused on the level ice condition
and only a few attempts have been so far made to research in pack condition. In this study, the
ice resistance under the pack ice condition was estimated using Multi-Material Arbitrary
Lagrangian Eulerian formulation and Fluid-Structure Interaction analysis technique of LSDYNA code. We especially considered the hydrodynamic loads between the ship and ice
floes, which could be important for the simulation in pack ice conditions. Then we discussed
the influence of the ship velocity, ice thickness and the concentration of pack ice condition.
Finally, the main limitations and future work directions of the numerical simulation work are
