METHOD OF IMPROVING ICEBREAKING PROPERTIES OF WATER VESSEL AND VESSEL DESIGNED ACCORDING TO THIS METHOD Russian patent published in 2012 - IPC B63B35/08 B63H5/08 B63H5/125 

FIELD: transport.

SUBSTANCE: method of manufacturing water vessel with improved characteristics of penetration into ice includes hull (1) with the first end (2) and the second end (3), which is provided with engine assembly creating main vessel propellent traction while vessel is moving with any end being forward. Engine assembly comprises at least three engine devices of which at least majority is antitorque propeller rotor devices (4) and located on at least two different distances from the second end (3) of vessel so that when the vessel is moving in ice or in ice formations with its second end (3) being forward, propeller rotor with one or more engine devices installed near the second end (3) of the vessel is positioned so that it breaks ice. Propeller rotor with one or more engine devices located further from the second end (3) of the vessel is positioned so that it moves broken ice or pieces of ice further from ice formations. Water vessel with improved characteristics of penetration into ice includes engine assembly with at least three engine devices of which at least majority is antitorque propeller rotor devices (4) and which are located on at least two different distances from the second end (3) of vessel so that when the vessel is moving in ice or in ice formations with its second end (3) being forward, propeller rotor with one or more engine devices installed near the second end (3) of the vessel is positioned so that it breaks ice.

EFFECT: vessel is capable to effectively break ice and move in heavy ice conditions.
