Abstract: Operation of ships in ice conditions is characterized by a considerable counteraction of the natural environment which is expressed, for instance, by a significant change of ice-going capability and manoeuvrability as compared with navigation in open water. A quantitative estimation of the effect of the ice cover on the manoeuvring qualities of ships is required both for the purpose of ensuring the safety of navigation and for optimizing the elements of the hull and the propeller-rudder complex (PRC) when designing new icebreaking and cargo ships. Owing to the complexity of ice characteristics and processes of interaction between the ice and the hull, the problem under consideration can be investigated by means of a theoretical-and-experimental method. In this method a physical-and-mathematical model is developed for a curvilinear motion of a ship in solid and broken ice. The model's adequacy was proved with the use of the data obtained from full-scale and model ice tests. The results of this research are discussed in the present paper.
