The invention discloses a ship seawater circulation system and a use method thereof. The ship seawater circulation system is provided with three seawater tanks and four seawater main pipes, the third seawater tank is located in the middle and provided with a left third main pipe and a right third main pipe which are independent, and the two third main pipes are connected with a first main pipe and a second main pipe of two side sea chests respectively; when the first seawater tank or the second seawater tank is cleaned and cannot work normally, the third seawater tank can supply water to a first cabin and a second cabin and meet the maximum use amount of seawater, and when the third seawater tank is cleaned, the first seawater tank supplies water to the first cabin, and the second seawater tank supplies water to the second cabin, and the maximum amount of seawater in each cabin can be ensured, and the normal operation of a ship power system is ensured. When a fire disaster occurs in the cabin where the first seawater tank or the second seawater tank is located, the third seawater tank can be prevented from being influenced by closing an isolating valve, so that the third seawater tank can at least guarantee normal water supply to one cabin, and the ship can return to the port safely.

    本发明公开一种船舶海水循环系统及其使用方法,船舶海水循环系统共有三个海水箱和四路海水总管,其中的第三海水箱位于中部,具有左右两个独立的第三总管,两个第三总管分别与两舷海底门的第一总管和第二总管连接,当第一海水箱或第二海水箱在被清洁而无法正常工作时,第三海水箱能为第一机舱和第二机舱供水且满足海水最大用量,当第三海水箱被清洁时,第一海水箱为第一机舱供水,第二海水箱为第二机舱供水,也能保证此时各机舱的海水最大用量,保证船舶动力系统的正常运行。当第一海水箱或第二海水箱所在的舱室发生火灾时,通过关闭隔离阀,能避免对第三海水箱造成影响,使第三海水箱至少能保证对一个机舱的正常供水,使船舶安全返港。
