Reg. 22.5

  46.1 The term “pump-room” means a cargo pump-room. Ballast piping is permitted to be located within the pump-room double bottom provided any damage to that piping does not render the ship’s pumps located in the “pump-room” ineffective.

  46.2 The double bottom protecting the “pump-room” can be a void tank, a ballast tank or, unless prohibited by other regulations, a fuel oil tank.

  46.3 Bilge wells may be accepted within the double bottom provided that such wells are as small as practicable and the distance between the well bottom and the ship's baseline measured at right angles to the ship's baseline is not less than 0.5h.

  46.4 Where a portion of the pump-room is located below the minimum height required in regulation 22.2, then only that portion of the pump-room is required to be a double bottom.
