Cargo ports or similar openings below the uppermost load line ( Regulation 21(2) ) (IACS interpretation LL.21)

 Cargo ports or similar openings may be submerged provided the safety of the ship is in no way impaired. It is considered that the fitting of a second door of equivalent strength and watertightness is an acceptable arrangement. In this case a leakage detection device should be provided in the compartment between the two doors. Further, drainage of this compartment to the bilges controlled by an easily accessible screw down valve, should be arranged. The outer door should preferably open outwards.
