摘要
FIELD: shipbuilding.SUBSTANCE: invention refers to the area of shipbuilding, is related to ice-breaking vessel thrusters and ice-breaking vessels themselves, and may be used for maneuvering in open water and in mooring mode under the conditions of ice brush. An ice-breaking vessel is proposed. The vessel is equipped with a thruster, a hydraulic blower of which the pumping unit of the fire extinguishing system with two output tubes, one of which blows water to the starboard side and the second, to the port side, the ends of board-output pipelines equipped with the propulsion nozzles located in the hull with orientation of its longitudinal axes aslant the vessel centerline with the maximum possible distancing of nozzles from the midship frame under water; there are stop check valves installed in the output segments of the pipelines equipped with drives connected to the central control console of the ice-breaking vessel.EFFECT: invention allows improving reliability of an ice-breaking vessel accompanied by improvement of strength performance of its hull, as well as reduction of costs for construction of an ice-breaking vessel.1 dwg
