摘      要：Cargo ship sailing within the ice channel that an assisting icebreaker tracks in the compact ice cover is the usual navigation practice for difficult ice conditions in freezing seas and Arcticwater *** the icebreaker or an ahead vessel stops before the insuperable ice obstacle or because of engine trouble,the danger of an emergency appears,namely of collision with the icebreaker or the ahead ship,if the interval between them is not sufficient for effective braking and *** paper presents the equation that describes the ship braking process within an ice channel and includes the thrust of the propeller that works under the reverse *** specific of this regime is the following:the ship continues the motion‘forwards’and the propeller rotates‘backwards’.An analytical method for description of the ship propeller work on the reverse regime is absent because of the detached flow on its *** paper describes the developed empirical method of this regime parameterization on the basis of serial models of propeller *** outcomes of this investigation are applied to a ship braking process simulation and the evaluation of the safe interval between the ship and the icebreaker.
