METHOD OF ICE COVER DESTRUCTION Russian patent published in 2020 - IPC B63B35/08 

FIELD: vessels and other watercrafts.

SUBSTANCE: invention relates to the field of shipbuilding, in particular to submarine vessels capable of destroying the continuous ice cover upon their ascent. Disclosed is method of ice cover destruction, which consists in attachment of vessel to ice by means of anchor and rope with subsequent filling of ballast tanks with outboard water. Then, by means of ship-mounted devices pre-installed in the ship ends, the ship is rotated about the vertical main axis of inertia and at the same time vertical pitching with frequency of resonant flexural-gravity waves (FGW) is imparted, at that, rope is attached to the ship at the point located on its rotation axis, and swivel is provided in the rope itself.

EFFECT: technical result consists in improvement of efficiency of ice breaking.
