| Summary: | The article notes that ensuring efficiency and safety of ice transport operations on the water transport is distinguished by a wide range of necessary actions, maneuvers, modes and dynamic working methods of the vessels. The assessment of vessel ice performance in special operating conditions is of current interest. Using CAE technologies the range of actual tasks of vessel movement and joint maneuvering in different ice and navigational conditions is considered: the prediction of forming speed and qualitative condition of the ice channel in thick and limit compact ices due to different tactical working methods of several icebreakers; the efficiency and safety of the slow-moving transport vessel icebreaking assistance in compact ices. Due to the result analysis of multiple CAE modeling recommendations for the operation of the studied icebreaker and cargo fleet of different ice categories are given. These recommendations concern the choice of safe maneuvering distances, vessel control laws, performance of standard operations. © 2022 National Research Nuclear University. All rights reserved.
