At least two sea chests, located below the lightest waterline, as far apart as practicable and preferably on
opposite sides of the vessel, are to be provided. Each of the sea chests is to be capable of supporting the cooling of propulsion and auxiliary machinery and other services drawing sea water from the same sea chest.规范要求,每条船必须设计至少两个海底门,海底门位置必须在船舶最轻载水线之下,而且尽可能左右各设计一个。海底门是为了满足船上各类机械设备吸水用的。这就是一般意义的高低位海水门。应急海底门,顾名思义,一般是单独设计为船舶应急消防泵吸水用的。

高位在港用,低位航行,没有硬性要求,检修时可轮换用。应急海底门可做应急消防泵吸口用。在船轮机员~~望采纳

深水域航行时用低位,可以防止船舶摇晃时(高位容易露出水面)进入空气,高位阀在浅水域可以不容易吸入淤泥
