I found these Chinese papers "
The application and development of watertight door on foreign naval warships" and "
Discussion on the Selection of Marine Watertight Door" which is from Naval Armament Department of PLA.
Conclusion -
从国外海军舰船水密门应用和发展可以看出，美国海军在水密门的设计、试验、使用和维护等方面均有较为系统的规范标准。针对我国舰船水密门关闭不严、承载能力较弱、缺乏抗冲击指标要求、规格类型多、耐腐蚀能力差、难于维护保养、标准规范体系不完善等问题，为了进一步规范水密门设计选型，改进水密门的性能，建议开展必要的系统性研究工作，深入分析、解读国内外规范要求的内涵，广泛听取使用部队的意见，从提高承载能力、增强抗冲击性能、提升标准化水平、减轻重量、提高耐腐蚀能力等方面入手，修改完善我国规范中有关舰船用门的设计选型方法和要求，以进一步提高我国舰艇的抗损能力。

From the application and development of watertight doors of foreign naval ships, it can be seen that the US Navy has relatively systematic norms and standards in the design, test, use and maintenance of watertight doors. In order to further standardize the design and selection of watertight doors, the watertight doors of Chinese ships are not tightly closed, the carrying capacity is weak, the lack of impact resistance index requirements, many types of specifications, poor corrosion resistance, difficult maintenance, and imperfect standard specification systems. To improve the performance of watertight doors, it is recommended to carry out necessary systematic research work, in-depth analysis and interpretation of the connotation of domestic and foreign normative requirements, and extensively listen to the opinions of user units, from improving bearing capacity, enhancing impact resistance, improving standardization level, and reducing weight, improve corrosion resistance and other aspects, modify and improve the design and selection methods and requirements of ship doors according to our country's codes, so as to further improve the damage resistance of our ships.
