C40 SAFETY OF LIFE AT SEA 



« 



(o) (i) Where irunkways or tunnels for access from crew accommodation 

 10 the stokehold, for piping, or for any other purpose are carried through 

 main transverse watertight bulkheads, they shall be watertight and in 

 accordance with the requirements of Regulation 16 of this Chapter. The 

 access to at least one end of each such tunnel or trunkway, if used as a 

 passage at sea, shall be through a trunk extending watertight to a height 

 sufficient to permit access above the margin line. The access to the other 

 end of the trunkway or tunnel may be through a watertight door of the type 

 required by its location in the ship. Such trunkways or tunnels shall not 

 extend through the first subdivision bulkhead abaft the collision bulkhead. 



(ii) Where it is proposed to fit tunnels or trunkways for forced draught, 

 piercing main transverse watertight bulkheads, these shall receive the special 

 consideration of the Administration. 



Regulation 14 



Openings in the Shell Plating below the Margin Line 



(a) The number of openings in the shell plating shall be reduced to the 

 minimum compatible with the design and proper working of the ship. 



(b) The arrangement and efficiency of the means for closing any opening 

 in the shell plating shall be consistent with its intended purpose and the 

 position in which it is fitted and generally to the satisfaction of the 

 Administration. 



(c) (i) If in a between decks, the sills of any sidescuttles are below a line 

 drawn parallel to the bulkhead deck at side and having its lowest point 2^ per 

 cent, of the breadth of the ship above the deepest subdivision loadline, all 

 sidescuttles in that between deck shall be of the non-opening type. 



(ii) All sidescuttles the sills of which are below the margin line, other 

 than those required to be of a non-opening type by sub-paragraph (i) of this 

 paragraph, shall be of such construction as will effectively prevent any person 

 opening them without the consent of the master of the ship. 



(iii) (1) Where in a between decks, the sills of any of the sidescuttles 

 referred to in sub-paragraph (ii) of this paragraph are below a 

 line drawn parallel to the bulkhead deck at side and having its 

 lowest point 4^ feet (or 1 • 37 metres) plus 2\ per cent, of the 

 breadth of the ship above the water when the ship departs from 

 any port, all the sidescuttles in that between decks shall be closed 

 watertight and locked before the ship leaves port, and they 

 shall not be opened before the ship arrives at the next port. 

 In the application of this sub-paragraph the appropriate 

 allowance for fresh water may be made when applicable. 

 (2) The time of opening such sidescuttles in port and of closing 

 and locking them before the ship leaves port shall be entered in 

 such log book as may be prescribed by the Administration.
