The breaking of ice sheets using shock waves produced by a pulsed power generator is suggested as a new method for navigation of icebreakers in order to realize safe and quick navigation in icebound sea. The shock wave can be produced by discharge formation between the electrodes contacted to an ice sheet. Experimentally, the breaking of ice was achieved. When the ice was broken for an applied voltage of 48 kV, a maximum discharge current of approximately 1.5 kA, a maximum discharge power of approximately 40 MW and a discharge energy of approximately 33 J were obtained. The onset of discharge occurs approximately 30 μs after applying the voltage. From the photograph and the voltage-current characteristics it seems that arc discharge occurs at the surface of the ice.
