Influence of Velocity on Ice-Cone Interaction

A series of upward breaking cone tests was conducted at NRC/IMD’s ice tank in level ice using EG/AD/S correct density model ice. Cone angles of 45° and 60° were tested. The effect of ice draft velocity in the range 0.005 to 0.5 m/s was studied for ice thicknesses ranging from 35 to 110 mm. The mean peak forces in both horizontal and vertical directions were measured and found to be almost independent of Froude Number below 0.02, but increased significantly at higher Froude Numbers. The effect of speed for upward breaking conditions was found to be less than similar conditions for downward breaking cones.
