FIELD: transportation.
SUBSTANCE: icebreaking vessel propulsor comprises a winch with a drive motor and a rope connected to an anchor installed in front of the vessel, as it moves. The anchor is made under the ice and comprises ballast water tanks with a pump, propellers and a top-mounted plate with a serrated outer surface. The plate with a serrated outer surface interacts with the bottom surface of ice. The rope is in combination with two blocks of pulleys, one of which is attached to the anchor under the ice, and the other - to the fore part of the vessel and is an element of a pulley tackle.
EFFECT: increasing the icebreaking vessel operation efficiency by increasing the propulsor efficiency factor.
