In ships where deck cargo may be carried, the positions of the hydrants shall be such that they are always readily accessible and the pipes shall be arranged as far as practicable to avoid risk of damage by such cargo.
 
 隔离阀应安装在所有用于非消防目的的露天甲板消防主管分支上。在可能载运甲板货物的船舶上，消防栓的位置应使其始终易于接近，且管道应尽可能布置，以避免因此类货物而受损的风险。

Ready availability of water supply 随时供水 

The arrangements for the ready availability of water supply shall be:
 供水随时可用的安排应为：

In passenger ships:在客船上：

1.Of 1,000 gross tonnage and upwards such that at least one effective jet of water is immediately available from any hydrant in an interior location and so as to ensure the continuation of the output of water by the automatic starting of one required fire pump;

总吨位为1000吨及以上的船舶，必须确保从任何内部位置的消防栓立即可用至少一个有效的水射流，并确保通过自动启动一个必需的消防泵来持续供水。

2.Of less than 1,000 gross tonnage by automatic start of at least one fire pump or by remote starting from the navigation bridge of at least one fire pump. If the pump starts automatically or if the bottom valve cannot be opened from where the pump is remotely started, the bottom valve shall always be kept open; and

对于总吨位小于1000吨的船舶，至少有一台消防泵应能自动启动，或者至少有一台消防泵可以从驾驶台上远程启动。如果消防泵自动启动，或者在远程启动消防泵的地方无法打开底阀，则底阀应始终保持开启状态；并且

3.If fitted with periodically unattended machinery spaces in accordance with regulation II-1/54, the Administration shall determine provisions for fixed water fire-extinguishing arrangement for such spaces equivalent to those required for normally attended machinery spaces;

如果根据规则II-1/54配备了定期无人值守机舱，行政当局须确定该等机舱的固定水灭火装置的规定，相当于正常有人看管的机舱；

In cargo ships: 在货船上：

To the satisfaction of the Administration; and

为满足主管机关要求，及
 
With a periodically unattended machinery space or when only one person is required on watch, there shall be immediate water delivery from the fire main system at a suitable pressure, either by remote starting of one of the main fire pumps with remote starting from the navigating bridge and fire control station, if any, or permanent pressurisation of the fire main system by one of the main fire pumps, except that the Administration may waive this requirement for cargo ships of less than 1,600 gross tonnage if the fire pump starting arrangement in the machinery space is in an easily accessible position.

在周期性无人值守的机舱或仅需要一人值班时，应能从消防总管系统立即以适当的压力供水，这可以通过以下方式实现：一是从驾驶台和消防控制站（如果有的话）远程启动主消防泵之一；二是通过主消防泵之一对消防总管系统进行持续性加压。不过，如果机舱内的消防泵启动装置的位置易于接近，主管机关可以对总吨位小于1600吨的货船免除这一要求。

Diameter of fire mains 消防总管直径

The diameter of the fire main and water service pipes shall be sufficient for the effective distribution of the maximum required discharge from two fire pumps operating simultaneously, except that in the case of cargo ships, the diameter need only be sufficient for the discharge of 140 m3/h.

消防主管和供水管道的直径应足够大，以便有效地分配两台消防泵同时运行时所需的最大排量，但对货船而言，只需足够分配140立方米/小时的排量即可。

Isolating valves and relief valves 隔离阀和安全阀

1.Isolating valves to separate the section of the fire main within the machinery space containing the main fire pump or pumps from the rest of the fire main shall be fitted in an easily accessible and tenable position outside the machinery spaces. The fire main shall be so arranged that when the isolating valves are shut all the hydrants on the ship, except those in the machinery space referred to above, can be supplied with water by another fire pump or an emergency fire pump. The emergency fire pump, its seawater inlet, and suction and delivery pipes and isolating valves shall be located outside the machinery space. 

应在机械处所外易于到达且可保持的位置安装隔离阀，以将装有主消防泵或水泵的机械处所内的消防总管部分与消防总管的其余部分分隔开。消防总管应如此布置，以便当隔离阀关闭时，船上除了上述机械处所中的消火栓外，所有消火栓都可以由另一台消防泵或应急消防泵供水。应急消防泵、其海水进口、吸入和排出管以及隔离阀应位于机械处所外。

2.A valve shall be fitted to serve each fire hydrant so that any fire hose may be removed while the fire pumps are in operation.

每个消防栓应安装一个阀门，以便在消防泵运行时拆除任何消防软管。

3.Relief valves shall be provided in conjunction with fire pumps if the pumps are capable of developing a pressure exceeding the design pressure of the water service pipes, hydrants and hoses. These valves shall be so placed and adjusted as to prevent excessive pressure in any part of the fire main system.

如果消防泵能够产生的压力超过给水管、消防栓和软管的设计压力，则应与消防泵一起提供安全阀。这些阀门的放置和调整应防止消防总系统任何部分的压力过大。

4. In tankers, isolation valves shall be fitted in the fire main at poop front in a protected position and on the tank deck at intervals of not more than 40 m to preserve the integrity of the fire main system in case of fire or explosion.

在油轮上，应在船尾前方的消防总管上安装隔离阀，并在油舱甲板上每隔不超过40米安装隔离阀，以保护位置，确保在火灾或爆炸情况下消防总管系统的完整性。

Number and position of hydrants 消火栓的数量和位置

The number and position of hydrants shall be such that at least two jets of water not emanating from the same hydrant, one of which shall be from a single length of hose, may reach any part of the ship normally accessible to the passengers or crew while the ship is being navigated and any part of any cargo space when empty, any ro-ro space or any vehicle space in which latter case the two jets shall reach any part of the space, each from a single length of hose. Furthermore, such hydrants shall be positioned near the accesses to the protected spaces.
 
消防栓的数量和位置应确保至少有两个水柱能够达到船上通常可供乘客或船员使用的任何部分，这些水柱不能来自同一个消防栓，其中至少一个水柱应来自一段单独的软管。当船只在航行时，以及在任何空的货舱、任何滚装空间或任何车辆空间内的任何部分，这两种水柱都应能够达到，每种水柱都应来自一段单独的软管。此外，这样的消防栓应位于通往受保护空间的入口附近。

Pressure at hydrants 消火栓压力

With the two pumps simultaneously delivering water through the nozzles the following minimum pressures shall be maintained at all hydrants:
 
当两台水泵同时通过喷嘴供水时，所有消防栓都应保持以下最低压力：
