23. Subdivision load lines
(1) Every ship to which these regulations apply shall be marked on its side amidships with the subdivision load lines assigned to it by the Director. The marks shall consist of horizontal lines 25 millimetres in breadth and 230 millimetres in length for any ship to which Part IV of the Ordinance applies and 305 millimetres in length for any other ship. The marks shall be painted in white or yellow if the background is dark or in black if the background is light and, if the sides of the ship are of metal, they shall be cut in, centre punched or indicated by welded beads; if the sides of the ship are of wood, the marks shall be cut into the planking to a depth of not less than 3 millimetres; if the sides are of other materials to which the foregoing methods of marking cannot effectively be applied, the marks shall be permanently affixed to the sides of the ship by bonding or some other effective method.
(2) The subdivision load lines shall be identified with the letter C, and, in ships of Class I or Class II, with consecutive numbers beginning from the deepest subdivision load line which shall be marked C1. In ships of Class II(A)—
(a) if there is only one subdivision load line, it shall be identified with the letter C;
(b) if there is more than one subdivision load line, the subdivision load lines shall be identified with the letter C and with consecutive letters beginning from the deepest subdivision load line, which shall be marked CA.
The identifying letters and numerals shall in every case be painted and cut in or centre punched or indicated by welded beads or otherwise marked as appropriate, on the sides of the ship in the same manner as the lines to which they relate.
(3) Ships to which this Part applies and which are assigned freeboards and are required to be marked with load lines under Part IV of the Ordinance shall be marked as follows—
(a) where the lowest of the ordinary load lines is higher on the ship’s side than the deepest subdivision load line, the latter shall form part of the same marking, the vertical line of the grid being extended downwards as necessary to reach the lowest subdivision load line. The subdivision load line or lines shall appear on the after side of the vertical line;
(b) where the deepest subdivision load line coincides or nearly coincides with the fresh water line, the subdivision marking C1 may be indicated on the forward side of the grid;
(c) where an “all seasons” freeboard is assigned and the deepest subdivision load line coincides with the horizontal line intersecting the load line mark, a vertical line shall be marked extending downwards from the fresh water load line to reach the subdivision load line marked C1 on the after side of the vertical line.

24. Exhibition of damage control plans
In every ship to which this Part applies there shall be permanently exhibited, for the information of the officer in charge of the ship, plans showing clearly for each deck and hold the boundaries of the watertight compartments, the openings therein, the means of closing such openings, the position of the controls and the arrangements for the correction of any list due to flooding. In addition, booklets containing such information shall be made available by the owner for the use of the officers of the ship.

27. No provision.

28. Application of Part III
This Part applies to every passenger ship to which these regulations apply.

29. General
Every ship to which these regulations apply shall be provided with an efficient pumping plant capable of pumping from and draining any watertight compartment in the ship, other than a space permanently appropriated for the carriage of fresh water, water ballast or oil and for which other efficient means of pumping or drainage is provided, under all conditions likely to arise in practice after a casualty, whether or not the ship remains upright. Wing suctions shall be provided if necessary for that purpose. Efficient arrangements shall be provided whereby water in any watertight compartment may find its way to the suction pipes. Efficient means shall be provided for draining water from all insulated holds and insulated between decks in such a ship:
Provided that the Director may allow the provision for drainage to be omitted in a particular compartment if he is satisfied—
(a) that having regard to the calculations made in accordance with the conditions set out in Schedule 3, the safety of the ship will not thereby be impaired; and
(b) that the provision of drainage would otherwise be undesirable.

30. Number and type of bilge pumps: ships of Class I and Class II
(1) Every ship of Class I or Class II shall be provided with power pumps connected to the bilge main in accordance with the following table—
Table

Criterion numeral  Less than 30  30 and over   Main engine pump (which may be replaced by one independent power pump)    1    1   Independent power pumps  2  3  
(2) Such pumps shall be arranged as follows—
(a) one of the pumps shall be an efficient emergency pump of a submersible type having its source of power and the necessary controls situated above the ship’s bulkhead deck. Such pump and its source of power shall not be installed forward of the collision bulkhead or nearer to the side of the ship than one-fifth of the breadth of the ship measured at right angles to the centre line of the ship at the level of the deepest subdivision load line; or
(b) the power pumps in the ship and their sources of power shall be so disposed throughout the ship’s length that under any condition of flooding which the ship is required to withstand at least one such pump in an undamaged watertight compartment will be available.

31. Number and type of bilge pumps: ships of Class II(A)
(1) Every ship of Class II(A) shall be provided with bilge pumps in accordance with the following table—

Table

Number of Pumps   Length of Ship in metres  MainEnginePump*  IndependentPowerPumps  Hand Pumps†   Under 15  1  —  One of the lever type for each watertight compartment or one of the crank type   15 and under 30.5  1  1  One of the lever type for each watertight compartment or one of the crank type   30.5 and under 76  1  1  One of the crank type   76 and over  1  2  —  * The main engine pump may be replaced by one independent power pump.  † The hand pumps specified in this column may be replaced by one independent power pump. (E.R. 3 of 2022) 
(2) In every such ship of 76 metres in length or over and in every such ship of under 76 metres in length in which a hand pump is replaced by an independent power pump, regulation 30(2) shall apply to such a ship as it applies to ships of Class I or Class II.

32. No provision.
