FIELD: transportation.
SUBSTANCE: method of breaking ice cover is proposed, consisting in attaching a vessel to ice by means of an anchor and a cable, followed by periodically filling ballast tanks with seawater, draining them at a frequency equal to the frequency of the resonant flexural-gravity waves excited in the ice cover by dynamic loads, the cable being selected according to the conditions for ensuring the sinking termination of the vessel when it reaches its maximum vertical speed.
EFFECT: increasing the thickness of the ice cover to be broken.
