5.2 Special provisions for multi-deck ships

  5.2.1 When a solid bulk cargo is loaded only in lower cargo spaces, it shall be trimmed sufficiently to equalize the mass distribution on the bottom structure.

  5.2.2 When solid bulk cargoes are carried in 'tween decks, the hatchways of such 'tween decks shall be closed in those cases where the loading information indicates an unacceptable level of stress of the bottom structure if the hatchways are left open. The cargo shall be trimmed reasonably level and shall either extend from side to side or be secured by additional longitudinal divisions of sufficient strength. The safe load-carrying capacity of the 'tween decks shall be observed to ensure that the deck structure is not overloaded.

  5.2.3 If coal cargoes are carried in 'tween decks, the hatchways of such 'tween decks shall be tightly sealed to prevent air moving up through the body of the cargo in the 'tween decks.
