How do icebreaker ships work?
Icebreakers clear paths by pushing straight into frozen-over water or pack ice. The bending strength of sea ice is low enough that the ice breaks usually without noticeable change in the vessel’s trim. In cases of very thick ice, an icebreaker can drive its bow onto the ice to break it under the weight of the ship.
