主机燃油系统进口阀（手动)离主机的距离？MSC要求？

cz_hhh

听说MSC对这个手动阀门离主机的距离有要求？小弟还找不到，要请教各位师傅了！

5米以外，如有隔离（比如可以遮挡火焰的）可以5米以内，

五米以外好像远了一点，请教三楼楼主，如果五米内，这个阀隔离一般怎么做，才可以说达到阻挡火焰？

2 Fuel oil isolation valves for multi-engines

2.1. In order to fulfil SOLAS regulation II-2/4.2.2.5.5, isolating valves should be located and operable from a position not rendered inaccessible by a fire on any of the engines.

2.1.1. Where practicable, isolating valves should be located at least 5 m away from engines in any direction. If this is not possible, the operating position of the valves should be protected by an obstruction. Figure 3-8 shows an example of protection by obstructions.

2.1.2. If the above is impracticable, other means of protection capable of enabling access to the isolating valves in the event of a fire might be acceptable.

2.1.3. Figure 3-9 shows the possible areas affected by fire and figure 3-10 shows a schematic diagram of a typical isolation valve arrangement.

2.1.4. Isolating valves controlled remotely could be acceptable. In this case, the operating mechanism should be protected from fire.

以前做个2种情况，一个是隔离阀设计的是手动快关阀的，使用钢丝绳的，但是很容易坏，后来船东提出使用截止阀，然后将阀柄延伸至（使用小轴传动）集控室门口，以主机隔离阀到操作口刚好5.3米。这样就过去了。
后来想是否可以做个挡板的形式放在阀前面，后来船东说这个方案太难看，船检说可行，或者说把阀放在舱壁拐角处也可以起到隔离火焰。。。但是船检只是说可以让我们参考，并没有认同。

一般我们将此阀设计成快关阀，如果不是，需将此阀移到5米以外

学习了...回头船上看看他们是不是这样做的
