STUDY OF SHIP ICE PERFORMANCE IN NARROW CHANNELS

The demand for natural resources (petroleum, natural gas, minerals) implies a continuing need for increased activity in the polar regions; this in turn demands the use of large ice class cargo carriers. The growth of the dimensions of ice class ships is inhibited by the dimensions of icebreakers employed in convoys. The width of a channel controlled by the breadth of the icebreaker has proved one of the most important factors affecting ship speed in the icebreaker channel. The objective of this study was the development of a practical assessment method for the effects of relative channel width on ship speed in an icebreaker channel. Some full scale results and the results of model tests at the Arctic and Antarctic Institute, Leningrad, are given.
