Regulation II-1/10 . Peak and machinery space bulkheads, shaft tunnels, etc.,
in passenger ships1 In paragraph 4, the words .all parts. should be interpreted to include any ramp which is
attached to the extension.
2 In ships constructed before 1 July 2006, the interpretation in paragraph 1 above should apply
no later than the date of the first renewal survey after 1 October 2006.
Regulation II-1/12 . Peak and machinery space bulkheads, shaft tunnels, etc. (revised SOLAS chapter II-1)3 By resolution MSC.194(80), amendments to SOLAS chapter II-1 were adopted which are
expected to enter into force on 1 January 2009; and paragraphs 3 to 5 of the existing
regulation II-1/10 have been transformed into paragraphs 6 and 7 of regulation 12 of the
aforementioned revised SOLAS chapter II-1. If ships are to comply with paragraphs 6 and 7 of
regulation 12 after the entry-into-force date on 1 January 2009, the following interpretation to
SOLAS regulation II-1/12.6 should apply to those ships:
"Where a long forward superstructure is fitted, the collision bulkhead should be extended
weathertight to the deck next above the bulkhead deck. The extension need not be fitted
directly above the bulkhead below provided that all parts of the extension, including any part
of the ramp attached to it are located within the limits prescribed in paragraph 1 or 2 of, with
the exception permitted by paragraph 7 in, regulation II-1/12 and that the part of the deck
which forms the step is made effectively weathertight. The extension should be so arranged
as to preclude the possibility of the bow door or ramp, where fitted, causing damage to it in
the case of damage to, or detachment of, a bow door or any part of the ramp."
