The invention relates to a hybrid power and propulsion system of an icebreaker, a power system and a propulsion system of the hybrid power and propulsion system both adopt a hybrid type, and the power system adopts a hybrid type of mechanical drive and electric drive to form the hybrid power system. The propulsion system is a hybrid propulsion system formed by mixing a shaft propeller propulsion system and a pod propulsion system. The shaft propeller propelling system is mechanically driven, two main engines are combined in parallel, and main propelling is achieved through a reduction gear box driving shaft system, PTO/PTI and an adjustable pitch propeller. The pod propulsion system is driven by electric power, is powered by a plurality of generators, and drives a pod propeller to realize main propulsion and steering through a distribution board, a frequency converter, a transformer, a propulsion motor and the like. By adopting the hybrid power and propulsion system, the sailing performance of the icebreaker under various working conditions can be effectively improved, including energy conservation and emission reduction, ice region maneuverability and scientific investigation silence.
