Commonwealth Consolidated Regulations

NAVIGATION (CONSTRUCTION) REGULATIONS 1968 - REG 18

(1)

So far as is practicable, a ship shall be so constructed as to keep at a minimum unsymmetrical flooding when the ship is in a damaged condition.

(2)

If the margin line of a ship may become submerged during the flooding assumed for the purposes of the calculation referred to in the Second Schedule, the Authority may, after such investigations as it considers necessary, require that the construction of the ship shall be such that it will be possible to ensure:

(a)

that the maximum angle of heel during any stage of the flooding will not be such as will endanger the safety of the ship; and

(b)

that the margin line will not be submerged in the final stage of flooding.

(3)

Where it is necessary to correct large angles of heel, the means adopted shall be self-acting or, if cross-flooding fittings are used, the controls for those fittings shall be capable of being operated from above the bulkhead deck and the time that those fittings take for equalization shall not exceed fifteen minutes.

(4)

If cross-flooding fittings are provided in a ship, the Authority may require that those fittings and the maximum heel of the ship before equalization shall be such as will not endanger the safety of the ship.
