Abstract: This study investigated the collision of a ship with an ice floe by conducting a small-scale model test with a synthetic ice piece and numerical analysis. In the model test, the motion of the synthetic ice was restricted, the collision experiment was conducted, and the carriage velocity, the force acting on the ship, and the motion of synthetic ice were measured. In addition, numerical simulation was conducted of the situation immediately before the collision with the ship and the piece of ice. Results show that the ice motion in the numerical analysis is qualitatively identical to that of the experiment. In the numerical analysis, ice moved greatly before the model test. The ship moved suddenly in numerical analysis, probably because a wave larger than that in the experiment propagates. In addition, the effect of the reflected wave is apparent in the numerical analysis. Both the model test and the numerical analysis must be improved.
