如图所示,两根快关阀拉绳,从机舱穿过水密舱壁,到达舵机舱,钢丝绳是穿过DN15的套管的。
但是问题来了,这个套管不能保证水密的。
技术部说公约有这方面的解释,可以允许轻微浸水,不能大于710mm2,船检方面还没沟通,各位船友请指教。谢谢!
MSC.281(85) - PART B- REGULATION 7 Regulation 7.7 1 Pipes and valves directly adjacent to a bulkhead or to a deck can be considered to be part of the bulkhead or deck, provided the separation distance is of the same order as the bulkhead or deck stiffening structure. The same applies for small recesses, drain wells, etc.
2 The provision for allowing “minor progressive flooding” should be limited to pipes penetrating a watertight su BDIvision with a total cross-sectional area of not more than 710 mm2 between any two watertight compartments.
