As per SOLAS, ER is categoried as space 6, while ECR, normally space 7, i.e., 'other machinery spaces'. Bulkhead between them will be a A-0 one.  
  
Doors on the bulkhead should be A-0 fire doors.(That's what we called 'fire integrity') And they must be self-closing to prevent the penetration of flame and smoke.
  
In addition, actions must be taken to avoid extra viberation and noise. 90 dB(A) is the limit of noise level in IMO's Resolution.
  
And, if ECR is exposed it's floor over ER, this floor must be insulated to a degree of A-60.

We can NOT think A-0 dividion has nothing to do with fire-retarding.
It includes two facts:
  
1: required structural strength;
  
2: fire-retarding performance; (refer to FTP code for more details)
  
So, when treating with these beams/stiffeners penetrating the margin bulkheads, patches is a must. This is most important!
  
Another interesting item is the windows on bulkheads of ECR.
Ruls&Regulations did not require the fire-retarding performance of these duty windows. While, some Classification Societies(such as ABS) require that these windows must be of safe type, i.e., although broken, segements of glass should not fall down to the ground--they still remain their original shape and size. So the glass must be inserted with mini steel mesh, or, the glass can be covered with a transparent film.
This 'safe' concept is absolutely not coincide with what we knew, the concept of 'safe toughed glass'. Anyway, this is what glass manufacuturers concern with. You just take it easy.

shuttle_wong见解我同意,也很长见识(尤其是英语方面)事实上集控室本身就是A0级的壁子,它是不允许有贯通孔或缝隙的,即便有穿舱件也要满焊,所以防火要求不用过于苛刻!

历害呀!
不知道现就职于何处呢?

A级分隔的话,是要求舱室的整个周界都是A级分割
哪怕是一个窗或是小孔,都构不成A级分隔
  
但是也必须明确一个概念
并不是所有的钢质围壁都是为了A级分隔而设置的
  
机舱集控室的窗就构不成A级分隔
  
应该明白,我们所做的设计应该是使船东能以最低的成本
造出适合的,好的船

说起集控室的窗,据说他也要有特殊要求,就是一旦被破坏,不能够有碎片落下来,至于他的防火性能我就不大清楚了。

防火在船舶设计中也是很重要的一环
特别是对于
化学品船和油船
  
现在SOLAS对散货船的防火要求也有增强
  
希望有大虾可以宣讲一下有关的规范和要求

规范太多
不是所有的人都能记得住
解释得了的

按规范做事。

我同意上面一个兄弟的说法,就是对于在机舱内的engine control room而言,solas的规定比较松啦。因为这个集控室要开两扇大窗的嘛。所以可以认为是属于category A machinery room,所以可以不用做到A-60级别,但也要隔热、隔音。门也要做成自闭式。

那么
机舱内的集控室是不是属于
控制处所呢?
按照控制处所的定义来看
应该是的
  
那为什么
又要求不高呢?

The propulsion machinery control room is regarded as control station, provided that this control room locates outside the space where propulsion machinery locates.
(SOLAS definition)
  
If ECR in ER, it's should not be categoried as Control Station;
If not, ie., ECR in superstructure or something like that, it's Control Station.

your mean is :
if the engine control room in engine room , it is a control room;
if it is not in the engine room , it is not a control room  
right ?

I must demonstrate the issue more clearly:
  
the first situation, ECR's in ER==>it is not a must to treat it as a Control Station.
If you category it as a Control Station, Classification Societies and Owner will  normally accept that 'cause you just give it extra protection.
  
the second situation, ECR's not in ER==>ECR's Control Station (normally).
  
Be attention that control room and control station are different concepts. Control Station is a space that accommodates many controlling equipments to achiev combined/integrated founctions.

shuttle_wong兄说的有道理!

我觉得shuttle_wong兄说得非常详细,其实我在实际做的过程中,情况确实如此!船级社并不一定要求对于engine control room在机舱中的情况作为category A space来处理!
如果你一定这样处理,船级社当然不会说你有问题,船东如果不在乎造价的话,那也就没什么了。
可如果对于船厂而言,就给他们增加了难度和造价!因为,毕竟A-60的防火分割还要做试验.
