我不是啊我是个小厂的QC做过这个，建议你看机舱前壁的横剖面图看看和货舱相交的部分

再次把这我这个帖子顶出来，还是想请教相关的问题，不想再重新开贴:
在这个帖子里有前辈说关于A60延伸部位若碰到道门可以像上面图中那样处理，不用做A60防火措施，但我一直找不到相关的根据。

这个貌似油柜的东东上道门被包得严严实实的，好像SOLAS上说油柜温度超过220°时油柜要做隔热保护，那像这样的绝缘材料需要向船上提供证书吗？提供什么样的证书呢？谢谢……

机舱前壁A60防护是运输危险品的要求，如货舱内3米内不堆放危险品也可以不做A60。油柜壁如设置了高温报警（60度以下）也可以不需要设置A60绝缘。

这个只是防烫伤的，机舱内绝大多数超过60度的表面需进行隔热包裹，其材料不需要证书。

水密门不需要进行隔热规范上有说明道门也是水密门的一种。

居住区域的热水管穿过烟囱
需要做绝延伸吗
如果需要需对材料有什么要求

你告诉我，这条船是不是MHI造的，怎么图纸画的那么符合他们的风格，嘿嘿！

MHI是哪个厂啊，这个我真不知道，现在只记得当时做这条船时，船东是个希腊鬼，又暴又扣，被他骂得很惨，这条船辛辛苦苦做了17天，结果产值才做了三十多万美金，船籍是NK的，其它的就不记得了，时间隔得太久了！

哦！这一条不晓得，不过做过很多日本造的船，唯一的感觉就是：不管哪条船，他们的机舱布置得都很宽敞简约，设计得很人性化，体现在船上的很多细节上。还有就是钢板厚度根据使用年限设计得相当的合理！不像国内的一些船……

楼主搞错了。煤实际上不是属于危险品，只是属于MHB组（可能产生危险的货物），具体可以看IMSBC CODE，单凭要装煤就要将机舱前舱壁改造成A-60没有根据。除非这条散货船还要装其他的危险品。
另外，根据机舱的布置图，要将机舱前舱壁改造成A-60也是扯淡，完全曲解了公约的意思。装危险品的船需要A-60舱壁的目的是将机舱与货舱隔开，机舱和货舱之间隔着燃油舱和滑油舱完全起不到效果，反而增加了危险性。

哥们：5年前，因自己负责的产品的原因，我曾系统性研究过,当年的分析报告如下：
ABS规范范里面关于运煤的要求
问题的来由:在VLOC船交船前, 香港海事处提出, 如果运输煤的话, 应满足IMO BC Code,因为,XX船也将运输煤,因此应考虑同样的问题.
问题的处理:
1,经过咨询ABS, ABS答复为:煤不是SOLAS里规定的危险品,但ABS也将按IMO BC Code的要求进行图纸审核, 并在最后发关于BC CODE的证书；
２，ＡＢＳ规范里也有对有关运输煤的具体要求，是应用ＢＣ　ＣＯＤＥ的要求，在ＡＢＳ规范里见规范的章节：ABS2008 PART5C，section 5c-3-7( page 507)，为了方便阅读，现在将有关部门内容进行了对照翻译，供参考
３，ＡＢＳ认为仅货舱内是危险区域，首楼的房间（面向货舱有门），和货舱中间的甲板室均没问题；甲板面的电缆和照明设备也没问题．
４，本船现实设计中可能存在的问题：
４－１：每个货舱都设置有气体检测孔，但应查明是否有测量设备（甲烷/氧气/一氧化碳的浓度的仪器），尤其是测量污水井的样品的ＰＨ值的设备；
４－２：现在舱口围上是有取样孔，应查明舱口盖上有没有取样孔；
４－３：现在设置的警告牌仅是＂ＮＯ　ＳＭＯＫＩＮＧ＂，但应按规范要求的内容：警告牌表明吸烟,明火,燃烧,切割,气刨,焊接或其他火源是禁止的．
４－３：现在存在的最大问题是货舱相邻高温的燃油舱的问题，６＃和７＃货舱的顶边舱是燃油舱，ＡＢＳ认为，如果加热盘管仅设置在吸口附近，就不认为是高温，但现在，加热盘管布置为整个顶边舱斜板，则要求设置高温报警，防止加热温度超过４５．

三．翻译的ABS规范
规范的章节：ABS2008 PART5C，section 5c-3-7( page 507)
规范的条文:
3.7 Vessels Intended to Carry Coal in Bulk
3.7 计划用于运筹散装煤的船舶
3.7.1 Flag Administration (1998)
3.7.1 挂旗当局(1998)
Attention is directed to the requirements for the carriage of coal in bulk in the IMO BC Code
and their application as may be prescribed by the vessel’s flag administration. If requested by
the vessel’s owner and authorized by the Administration, the Bureau will review the plans and
carry out surveys in accordance with the above Code on behalf of the Administration.
注意事项直接引述IMO BC Code里关于运输散装煤的要求, IMO BC Code也在挂旗国当局的应用中描述,如果应船东和授权的挂旗国当局的要求,船级社也将代表挂旗国当局关于IMO BC Code方面对图纸进行审核和执行检验.
3.7.2 Hazardous Areas
3.7.2 危险区域
Areas where flammable or explosive gases, vapors or dust are normally present or likely to be
present are known as hazardous areas. For vessels intended to carry coal in bulk, the following
areas are to be regarded as hazardous areas:
对存在可燃气体或爆炸气体,蒸气,灰尘的区域必须显示或按危险区域的形式显示.对于用于运输散装煤的船舶,下列区域被认为是危险区域
• Cargo hold spaces,
货舱
• Enclosed and semi-enclosed spaces having a direct opening to cargo hold space, and
直接开口朝向货舱的封闭或半封闭的舱室
• Open deck areas within 3 m (10 ft) of cargo hold mechanical ventilation outlets.
货舱机械通风的出口在开敞甲板的3米范围内
3.7.3 Installation of Electrical Equipment in Hazardous Areas
3.7.3 对于危险区域的电气设备的安装要求
Electrical equipment installed in hazardous areas, identified in 5C-3-7/3.7.2, is to be:
位于按5C-3-7/3.7.2,规定的危险区域内的电气设备必须满足:
Intrinsically safe type (Ex ia or ib);
本质安全型(Ex ia or ib);
Flame-proof (explosion-proof) type (Ex d Group IIA T4);
防火(防爆)型(Ex d Group IIA T4);
Pressurized or purged type (Ex p); or
正压或吹除型(Ex p)
Increased safety type (Ex e) in open deck hazardous areas only.
增安型(Ex e)仅能用于开敞的甲板危险区域
See also 4-8-3/13 and 4-8-4/27.
该要求也可参见4-8-3/13 和 4-8-4/27.
3.7.4 Installation of Internal Combustion Engines in Hazardous Areas
3.7.4 在危险区域安装内燃机的要求
Where essential for the operation of the vessel, the installation of internal combustion engines
in hazardous areas, identified in 5C-3-7/3.7.2, may be permitted. This is subject to the
elimination of all sources of ignition from the installation; the engine exhaust being led
outside the hazardous areas, and the engine air intake being not less than 3 m (10 ft) from the
hazardous areas. Complete details are to be submitted for review in each case.
3.7.5 Cargo Hold Atmosphere Measuring Instruments (1998)

3.7.5 货舱气体探测设备的要求(1998)
3.7.5(a) Required measurements. Instruments are to be provided to measure the following in
the cargo holds:
3.7.5(a)要求的设备.应配备能够测量如下数据的设备
• Concentration of methane in the atmosphere;
甲烷气体的浓度
• Concentration of oxygen in the atmosphere;
氧气的浓度
• Concentration of carbon monoxide in the atmosphere; and
一氧化碳的浓度
• pH value of cargo hold bilge samples.
货舱污水井样品的PH值
In addition, where self-heating coals are to be carried, it is recommended that consideration be
given by the Owner/designer to provide the means for measuring the temperature of the cargo
in the range of 0°C (32°F) to 100°C (212°F) during loading operations and during the voyage.
Means for calibration of the above instruments are to be provided onboard.
另外,对于运输会自热的煤,建议船东和设计人员提供在装货和航行过程中测量货物温度的措施(在0-100度范围内),在船上应配备调校测温设备的装置

3.7.5(b) Arrangements of measurement. The required measurements and their readings are to
be obtainable without entry into the cargo hold, and without introducing a source of ignition
or otherwise endangering the cargo and cargo hold atmosphere. Instruments for measuring
methane, oxygen and carbon monoxide concentrations are to be provided, together with an
aspirator, flexible connection, a length of tubing and means for sealing the sampling hole, in
order to enable a representative sample to be obtained from within the hatch cover surroundings.
Alternative means for obtaining a representative sample will be considered.
3.7.5(b)测量布置.测量和读数应不必要进入货舱,也不会引起火源,或危及货物和舱内气体.测量甲烷/氧气/一氧化碳的浓度的仪器应提供,同时配备吸气器,软管,一段取样孔的短管和封头,以便取得在舱口盖内能代表舱内真实情况的数据,其他替代的方法也可以考虑.

3.7.5(c) Sampling points. Sampling points are to be provided for each hold, one on the port
side and the other on the starboard side of the hatch cover, as near to the top of the hatch cover
as possible. Each sampling point is to be fitted with a screw cap or equivalent and a threaded
stub of approximately 12 mm (0.5 in.) bore welded to the side of the hatch cover to prevent
ingress of water and air. Alternative sampling point arrangements/details will be considered.
3.7.5(c)取样点.每个货舱都必须设取样孔,左舷一个;在右舷的舱口盖上设置一个,应尽可能靠近舱口盖的顶点.每个取样孔必须安装一个螺帽或等同的装置,突出的取样短管约长12毫米,牢固焊接到舱口盖上以防止水或空气进入舱内. 其他替代的方法也可以考虑.

3.7.6 Warning Plate (1998)
3.7.6 警告牌(1998)
A permanent warning plate is to be installed in conspicuous places in cargo areas to state that
smoking, naked flames, burning, cutting, chipping, welding or other sources of ignition are
prohibited.
在货舱区的显著位置必须设置一个永久性的警告牌,表明吸烟,明火,燃烧,切割,气刨,焊接或其他火源是禁止的.

3.7.7 Hot Areas
3.7.7 高温区域
Coal is not to be stowed adjacent to hot surfaces having a temperature of 45°C or above.
Spaces adjacent to cargo holds that are likely to be hot, such as heated fuel oil tanks, are to be
provided with suitable measures to prevent the common boundaries from being raised to a
temperature beyond that considered safe for the carriage of the coal.煤不能存储在高于表面温度高于45°C和以上的相邻舱室.
对于通常属于高温的相邻舱室, 例如燃油舱,应设置防止相邻边界温度高于认为是运输煤的安全的温度(45°C).

ABS规范范里面关于运煤的要 ...

1. The Maritime Safety Committee, at its eighty-seventh session (12 to 21 May 2010), noting that the provisions of the may be applied from 1 January 2009 on a voluntary basis and are envisaged to become mandatory under the SOLAS Convention on 1 January 2011, recognized the need for clarification of the following stowage and segregation requirements:

.1. "This cargo shall not be stowed adjacent to hot areas." in paragraph 5 in the section for "STOWAGE & SEGREGATION" in the appendix to the individual schedule for BROWN COAL BRIQUETTES; and

.2. "The master shall ensure that this cargo is not stowed adjacent to hot areas." in paragraph 4 in the section for "Segregation and stowage requirements" in the appendix to the individual schedule for COAL.

2. The Committee agreed that the words "adjacent to hot areas" in these provisions should be interpreted as "boundary areas of the cargo hold in contact with the cargo, having a temperature consistently greater than 55°C during carriage of the cargo, such as can sometimes be experienced when heated fuel oil service tanks and fuel oil settling tanks have a common boundary with the cargo hold".

3. The Committee recommends that, in applying the aforementioned interpretation, the following is taken into account:

. "Heated fuel oil tanks adjacent to cargo spaces carrying these cargoes should not normally be considered as "hot areas" when the fuel oil temperature is controlled at less than 55°C; this temperature is not exceeded for periods greater than 12 hours in any 24-hour period; and the maximum temperature of the fuel oil reached does not exceed 65°C."

4. Member Governments are invited to use the aforementioned interpretation as guidance when applying the provisions of the and to bring it to the attention of all parties concerned.
