Abstract: ［Objective/Significance］ Under the synergistic effects of deep-sea environmental factors—such as high hydrostatic pressure，high salinity，low temperature，low dissolved oxygen，and microbial activity—metallic and alloy-based marine engineering equipment are prone to corrosion and fatigue failure，posing significant challenges to their long-term operation. Organic anti-corrosioncoatings have become one of the most widely used protection methods in deep-sea applications due totheir excellent anti-corrosion performance，ease of application，and high cost-effectiveness.［Analysis/Discussion/Progress］ This paper reviews recent advances in deep-sea anti-corrosionorganic coatings and key characterization techniques，with a focus on the critical factors influencingtheir corrosion protection performance in deep-sea environments. The effects of water uptake， interfacial adhesion，and mechanical properties on coating degradation are systematically discussed.Finally，the current challenges and future development trends of deep-sea anti-corrosion coatings are outlined，thus providing a foundation for more systematic and comprehensive future research.［Conclusion/Prospect］ Future efforts should focus on elucidating coupled damage mechanisms， developing integrated functional designs，advancing intelligent monitoring technologies，and achieving accurate service life prediction，which are pivotal to develop high performance organic coatings with long term corrosion resistance.
