Abstract: The increasing popularity of polar shipping routes poses greater challenge to the marine cold protection technology. Considering the importance of the cold-proof design of the sea chest, the key requirements of the sea chest in the ice region in the relevant specifications of the classification society are introduced in order to ensure the stable operation of the ship in polar environment. The current cold protection technologies are classified and analyzed from the structural design, structural layout and auxiliary deicing according to the principles of different cold protection technologies. The application of the cold protection measures based on different technical principles in different design schemes are highlighted by comparing the characteristics of four cold protection design schemes. The unique technical key points of the cold protection design of the sea chest in the ice region are summarized. It can provide ideas for promoting the scientificity and rationality of the cold protection technology of the sea chest in the ice region in subsequent researches.
