舵机间要设舱底水高位报警吗？

规范上没有相关要求。

我看你不懂规范吧，去查查到VDR的信号，有没有液位高报警。

如果舵机间计入破舱稳性，就需要，否则不做要求的。如是船东提前要求增加就另说。

请給进一步说明。

VDR的性能标准，不能作为要求舵机间装舱底水高位报警的2依据。

加舱底水高位报警,主要的目的是为了防止船舶在重载吃水（重载时海水很容易从舵杆盘根处进水）或者舵机间破损时，舵机间进水进而影响船舶航行时的安全性。舵机间的水密门一般也要加一个开启报警延伸至驾控台也是这个道理。

基本支持此观点，但是注意，有的舵机间的门（至机舱）是防火门，归根到底还是船体的破舱稳性计算中舵机舱是否计入稳性的要求。

这个就不清楚了应该是船体的破舱稳性计算。我在DNV官网上找了下，只有一个补充的协议，说的很含糊。这个可以问下你们那边的船检。

貌似不需要吧，好像没见过，在舵机间只有污水井，应该要因船而异吧

能给予更多说明？

zhangliang856

我也只有这个水平了，在DNV规范没找到必须要加报警这个明确要求，规范也不是面面俱到。所以没必要太纠结这个东西。按照常识船舶在重载吃水航行时，舵机室确实很容易进水。加个报警也在常理之中。

这个必须要有！！！

不够酷

一般有污水井，污水井里放个高位报警

15 Bilge high level alarms
15.1. On a vessel 8 m (26 feet) or more in length, a visual and audible alarm shall be provided at the operating station to indicate a high water level in each of the following normally unmanned spaces:

.1. a space with a through-hull fitting below the deepest load waterline, such as a lazarette;

.2. a machinery space bilge, bilge well, shaft alley bilge, or other spaces subject to flooding from sea water piping within the space; and

.3. a space with a non-watertight closure, such as a space with a non-watertight hatch on the main deck.
