Protection of openings in raised quarter-decks (Regulations 18(2) and 23 ) (IACS interpretation LL.46.Rev.2)

 By extension of regulation 23 and the interpretation of regulation 18(2) and (3) regarding miscellaneous openings in freeboard and superstructure decks, referred to above (see previous unified interpretation), deckhouses situated on a raised quarter-deck or on a superstructure of less than standard height may be treated as being on the second tier as far as the provision of deadlights and sidescuttles and windows is concerned, provided that the height of the raised quarter-deck or superstructure on which they are situated is equal to, or greater than, the standard quarter-deck height.

 Regarding the requirement to protect openings in superstructures (regulation 18(2)), it is considered that openings in the top of a deckhouse on a raised quarter-deck or superstructure of less than standard height having a height equal to, or greater than, the standard quarter-deck height should be provided with an acceptable means of closing but need not be protected by an efficient deckhouse or companionway as defined in the regulation provided that the height of the deckhouse is at least the height of superstructure.
