6.3 Doors

  6.3.1 footnote In passenger ships to which the International Convention for the Safety of Life at Sea, 1974 applies, doors should comply with regulations II-1/15 and 18 of this Convention.

  6.3.2 footnote In ships to which the International Convention on Load Lines, 1966, applies, doors should comply with regulation 12 of this Convention.

  6.3.3 footnote In fishing vessels to which the 1993 Torremolinos Protocol applies, doors should comply with regulation II/2 and regulation II/4 of this Protocol.

  6.3.4 In decked fishing vessels of 12 m in length and over but less than 24 m in length:

  • .1 Watertight doors may be of the hinged type and should be capable of being operated locally from each side of the door. A notice should be attached to the door on each side stating that the door should be kept closed at sea.

  • .2 All access openings in bulkheads of enclosed deck erections, through which water could enter and endanger the vessel, should be fitted with doors permanently attached to the bulkhead, framed and stiffened so that the whole structure is of equivalent strength to the unpierced structure, and weathertight when closed, and means should be provided so that they can be operated from each side of the bulkhead.

  • .3 The height above deck of sills in those doorways, companionways, deck erections and machinery casings situated on the working deck and on superstructure decks which give direct access to parts of that deck exposed to the weather and sea should be at least equal to the height of hatchway coamings as specified in 6.1.3.8.

  • .4 Where operating experience has shown justification and on approval of the competent authority, the height above deck of sills in the doorways specified in 6.3.4.3 except those giving direct access to machinery spaces, may be reduced to not less than 150 mm on superstructure decks and not less than 380 mm on the working deck for vessels 24 m in length, or not less than 150 mm on the working deck for vessels of 12 m in length. For vessels of intermediate length the minimum acceptable reduced height for sills in doorways on the working deck should be obtained by linear interpolation.
