7 The structural strength of every ship to which these Regulations apply shall be sufficient for the service for which the ship is intended; the plans specified in Schedule VI of the Hull Inspection Regulations shall be prepared taking full cognizance of all applicable requirements specified herein.
Application of Part
8 This Part applies to the following classes of ships if those ships are carrying more than 12 passengers:
(a) steamships of Class I and Class II; and
(b) steamships of 150 tons, gross tonnage, or over, that are ships of Class III or Class IV.
9 Every ship shall be subdivided into compartments by bulkheads that are watertight up to the bulkhead deck, the maximum length of which compartments shall be calculated in accordance with such of the provisions of Schedule I as apply to that ship; every other portion of the internal structure that affects the efficiency of the subdivision of the ship shall be watertight, and shall be of a design that will maintain the integrity of the subdivision.
Peak, Machinery Space and Shaft Tunnel Bulkheads
(1.1) In the case of a ship that has a forward superstructure, the collision bulkhead shall be extended weathertight to the deck next above the bulkhead deck and this extension shall
(a) be fitted directly over the collision bulkhead below, unless
(b) have a plating and stiffeners of such strength and construction as to be capable of supporting the pressure of a head of water up to the margin line, as if the extension formed part of a bulkhead immediately below the bulkhead deck.
(2) Every ship shall be provided with a watertight afterpeak bulkhead and with watertight bulkheads dividing the space appropriated to the main and auxiliary propelling machinery, boilers, and the permanent coal bunkers, if any, from other spaces; such bulkheads shall be watertight up to the bulkhead deck; provided that the afterpeak bulkhead may be stopped below the bulkhead deck if the safety of the ship is not thereby impaired.
(3) The stern gland shall be situated in a watertight shaft tunnel or other watertight space separate from the stern tube compartment and of such a volume that if the tunnel or space is flooded the margin line will not be submerged; the stern tube shall be enclosed in a watertight compartment, the volume of which shall be the smallest compatible with the proper design of the ship.
- SOR/95-254, s. 2
(a) in ships of no less than 50 m but less than 61 m in length, extends at least from the forward end of the machinery space to the collision bulkhead, or as near to that bulkhead as is practicable;
(b) in ships of no less than 61 m but less than 76 m in length, extends at least from the forward end of the machinery space to the collision bulkhead and from the aft end of the machinery space to the afterpeak bulkhead, or as near to those bulkheads as is practicable; and
(c) in ships of 76 m or more in length, extends at least from the collision bulkhead to the afterpeak bulkhead, or as near to those bulkheads as is practicable.
(1.1) Ships of no less than 24 m but less than 50 m in length that carry berthed passengers below the bulkhead deck shall be fitted with a watertight double bottom for the full length of compartments in which passenger spaces are located.
(2) When a double bottom is required by this section to be fitted in a ship, the inner bottom shall be continued out to the ship’s sides in such a manner as to protect the bottom to the turn of the bilge; the inner bottom shall be deemed to be adequate for this purpose if the line of intersection of the outer edge of the margin plate with the bilge plating is not lower at any point than a horizontal plane passing through the point of intersection with the frame line amidships of a transverse diagonal line inclined at 25 degrees to the base line and cutting it at a point one half of the ship’s moulded breadth from the middle line.
(3) Wells constructed in the double bottom for the purpose of drainage shall not be larger or extend downwards more than is necessary for such purpose, and shall not be less than 460 mm from the outer bottom or from the inner edge of the margin plate, provided that a well extending to the outer bottom may be constructed at the after end of a shaft tunnel.
(4) Wells for purposes other than drainage shall not be constructed in the double bottom; the Board may exempt any ship from the requirements of this subsection in respect of any well it is satisfied will not diminish the protection given by the double bottom.
(5) Nothing in this section shall require a double bottom to be fitted in way of watertight compartments used exclusively for the carriage of liquids, if the safety of the ship will not be impaired in the event of bottom or side damage by reason of the absence of a double bottom in that position.
(6) The Board may exempt any ship, other than a ship of Class I, from the requirements of a double bottom in any portion of the ship that is subdivided by application of a factor of subdivision not exceeding 0.5 if it is satisfied that the fitting of a double bottom in that portion of the ship would not be compatible with the design and proper working of the ship.
