The structural type is radically changed. The Japanese standard 5-2314-1995 hydraulic watertight door IP structure is adopted; the door plate and door structure are joint type; the width of the door is unified to 600 mm1. The manual hydraulic system is used to replace the structure, and the gear transmission is manual operation; the compression system schematic diagram and electrical control schematic diagram of the bottom closing watertight door are listed as appendices. This standard takes effect from the date of entry into force, and replaces CB/T 3007--1999, CB*634-84, and the appendix A and appendix B of this standard are indicative appendices. This standard is provided by Jiangnan Ship (Group) Co., Ltd. Single units that implement this standard: Jiangnan Shipyard (Group) Co., Ltd., Wuxi Lanhai Shipbuilding Co., Ltd., Dajinjin Xingguang Shipbuilding Co., Ltd., main contributors to this standard: Die Huanbo, Pan Zirong, Yang Antuo, Huo Weijing, Jianjin, Jing Guorong, this standard was first issued in October 1979 (CB*3007-79), secondly revised as the national standard (GB10840-89) in March 1989, and directly adjusted to CB/T3007-1999+CB3484 in June 1999. It was first issued in 1967 and first revised in May 1984.
