Hull Construction Regulations (C.R.C., c. 1431)

Regulations are current to 2013-04-29 and last amended on 2007-07-01. Previous Versions

  • 107. (1) Sections 105 and 106 do not apply to an existing ship unless

    • (a) the main propelling machinery of the ship is changed for machinery developing greater brake power;

    • (b) the main propelling machinery of the ship is changed and the difference in weight between the new and the old installation is, in the opinion of the Board, sufficient to adversely affect the stability of the ship; or

    • (c) the ship is modified to such an extent that, in the opinion of the Board, its stability is adversely affected.

  • (2) Where the Board is of the opinion that modifications made to a ship adversely affect its stability within the meaning of paragraph (1)(c), the owner of that ship shall submit such of the stability data described in section 106 as the Board may request.

  • SOR/95-254, s. 32(E).

  • 108. (1) In the case of a new ship, the owner shall, subject to subsection (2), submit to the Board in respect of the ship the following stability data:

    • (a) the forward and aft draughts when the watertight compartment aft of the engine room that would cause the greatest reduction in freeboard is completely flooded;

    • (b) the metacentric height when the watertight compartment aft of the engine room that would cause the greatest reduction in the metacentric height is completely flooded; and

    • (c) the metacentric height when the watertight compartment aft of the engine room that would cause the greatest reduction in the metacentric height in a partly flooded condition is flooded to that condition.

  • (2) Subsections 106(2) to (5) apply when computing the stability data referred to in subsection (1).

Subdivision of the Hull

  • 109. (1) In the case of a new ship, the ship shall be fitted with

    • (a) a collision bulkhead in an approved location; and

    • (b) a watertight bulkhead at the forward end and at the aft end of the main propelling machinery placed as close together as is practicable.

  • (2) Where the forward bulkhead of the engine room of any ship is fitted in an approved location, it may be approved as the collision bulkhead.

  • (3) Where, in the opinion of the Board, it is reasonable and practicable, every new ship that is propelled by steam engines shall be fitted with a watertight bulkhead between the boilers and the main engines.

Openings in Watertight Bulkheads

110. In the case of a new ship, where an access opening is fitted in the watertight boundary bulkhead of a watertight compartment referred to in section 104 or in any bulkhead referred to in section 109, the access opening shall, unless it is a tank manhole, be

  • (a) made as small as practicable;

  • (b) placed as near to the top of the bulkhead as is practicable, except in the case of an access opening between machinery spaces or to a shaft tunnel;

  • (c) reinforced so that the strength of the bulkhead is not reduced by the opening; and

  • (d) fitted with a watertight closing appliance that conforms to the requirements of section 111.

  • SOR/78-45, s. 1.
