The invention discloses an intelligent ship for arctic navigation. The intelligent ship comprises a voyage data recorder, an alarm management system, an ice load monitoring system, a stress monitoring system, an ice layer thickness and ice condition monitoring system, a longitudinal inclination optimization and navigational speed optimization system, a storage system, a noise and vibration monitoring system and an intelligent management system, wherein the voyage data recorder comprises a wave gauge, an anemorumbometer, a rotational speed meter, a fore-and-aft draft gauge and a satellite positioning receiver, and the alarm management system comprises a fuel thermometer, a fuel mass flow meter and a shaft power meter detection alarm system. A mariner adjusts the floatation condition, navigational speed and course of a ship according to data and information provided by the intelligent systems, so as to avoid icebergs or dangerous sea areas where ice layers are thick during arctic navigation, and then navigation safety is guaranteed; navigation resistance is reduced in ice-free or little-ice sea areas, and then oil consumption is reduced. Meanwhile, the maintenance and repair plan of equipment including a main engine and an auxiliary engine can be adjusted in time according to the monitored operation condition of machinery equipment.
