METHOD OF PRODUCING ICE FERRY Russian patent published in 2011 - IPC E01D15/14 

FIELD: transport.

SUBSTANCE: proposed method consists in freezing in steel ropes on ferry both sides over entire ferry length provided with preset elements rigidly jointed to said ropes. Prior to freezing in said elements, said ropes are pre-stretched. Said elements are made up of steel washers to be heated to temperature exceeding that of ice melting by feeding electric current there through. After immersing said elements in ice to depth half the ice entire thickness, current feed is terminated. Ice ferry surface thus prepared is subjected to effects of low ambient temperature (t<0°C) to complete freezing of water originating in channels of ice melting.

EFFECT: increased bearing capacity.
