一、检查情况

A general cargo ship built in year 2012 was inspected.Among other things,the following deficiency was issued by the PSCO,which the RO disagreed with. 

一艘 2012年建造的货船， PSC检查期间， PSCO开具的以下缺陷，RO有异议： 07120   Width of Em’cy escape trunk from E/R not reach to 800 mm at lower plate (code 17/70)

二、 RO主张

The RO expressed the view that the width of the emergency escape trunk would not be affected by this small metal piece that was cut-off. Moreover, from a structural point of view, this cut-out may cause shear forces if not considering the underneath supporting structure and may create a hard-point.

RO认为机舱应急逃生通道的宽度不受图中结构的影响，从结构上考虑，这个点切掉而不采取相应的措施将引起剪切应力。

三、相关参考材料 

四、东京备忘录研讨结论

1.Is the escape trunk in question affected by the piece of fitting/cut-off substantially (i.e.less  than 600mm)?

 1.本案例中逃生通道的宽度受焊接点的影响么？

 2.It would be more prudent to discuss and confirem with the flag and/or RO about such kind  of  matter and on the action to taken. 

 2.当遇到本案例中的情况时，与RO或船旗国沟通、讨论之后再决定更为妥当。

 3.Apart from the deficiency, please be reminded  that action code 70 is an inspection action code rather than a deficiency action code.Therefore it  should not be used against specific deficiency.

 3.避开本案例的缺陷不谈， PSCO应该注意的是：  行动代码 70是一个检查代码而不是一个缺陷代码，不应该用在具体缺陷之中。
