FIELD: shipbuilding; submarine vessels running under ice conditions and breaking ice cover by resonance method at surfacing in compact ice.
SUBSTANCE: while breaking the ice, ship makes several lanes at area of surfacing; number of lanes is dictated by safety of surfacing. Degree of breaking the ice is determined by maximum force of thrust of propeller.
EFFECT: enhanced safety of surfacing under ice conditions.
