我查了下对于空气管头的要求:
Loadline Regulation 2005 上 Regulation 20: Air pipes
(3) Air pipes shall be provided with automatic closing devices.
NK Part D 13.6.2 open ends of air pipes 规范:
2. All openings of air pipes leading above the weather deck are to be provided with automatic closing devices.
ABS 规范:
9.3.5 Protection of Vent Outlets
9.3.5(a) Protection from weather and sea water ingress (2010). All vents terminating in the
weather are to be fitted with return bends (gooseneck), or equivalent, and the vent outlet is to be
provided with an automatic means of closure i.e., close automatically upon submergence (e.g., ball
float or equivalent) complying with 4-6-4/9.3.7.
9.3.7 Vent Outlet Closing Devices (2003)
9.3.7(a) General. Where vent outlets are required by 4-6-4/9.3.5(a) to be fitted with automatic
closing devices, they are to comply with the following:
1) 为何有不同的解释啊?
2) 为何ABS规范中说空气管头要自动关闭装置,或则同等的,鹅颈头也可以,但是Loadline和NK规范没有说?
