Regulation 13–1 - Openings in watertight bulkheads and internal decks in cargo ships

Parent topic: Part B - Guidance on Individual Regulations

Paragraph 1

 If the transverse watertight bulkheads in a region of the ship are carried to a higher deck than in the remainder of the ship, openings located in the bulkhead at the step may be considered as being located above the freeboard deck.

 All openings in the shell plating below the upper deck throughout that region of the ship should be treated as being below the freeboard deck, similar to the bulkhead deck for passenger ships (see figure above), and the provisions of regulation 15 should be applied.
