The maneuvering of ships sailing in Polar Regions is much more complex than those in conventional waters, imposing hazards on ships sailing in Polar Regions. However, there are currently few analysis and research on the characteristics and maneuverability design requirements of polar icebreakers. This study introduces the polar environment related to the maneuverability of icebreakers, such as the wind, wave and current, shallow water, narrow waterway, low temperature and low visibility. It also analyzes the classification and ship characteristics of the icebreakers in Russia and other countries, and summarizes the relevant requirements of maneuverability standards for maneuvering devices on ice breakers with pod, multi-propeller and multi-rudder. In order to meet the requirement of maneuverability design, it introduces the maneuverability research methods such as the model test, full-scale test and numerical simulation of ice breakers, and the calculation methods for the ship-ice interaction forces such as the empirical formula method, finite element method and discrete element method. The above analysis and summary can provide references for the maneuverability design of icebreakers.
