FIELD: transport.
SUBSTANCE: invention discloses shape of outlines of ice breaker platform hull equipped with riser lines and turrets arranged in the hull fore, said turret allows spontaneous turn in direction of external force main vector and is fixed by anchor retention system connected with said turret.
EFFECT: decreased shift of platform at its turn under action of external forces brought by ice owing to increased speed, protection of turret and riser lines against contact with keel and submerged ice body.
