paragraph (1) of this Regulation shall be increased by 50 per
cent. Where the sheer is less than the standard the percentage
shall be obtained by linear interpolation.
(3) Where a ship fitted with a trunk does not comply with the
requirements of Regulation 36 (1) (e) or where continuous or
substantially continuous hatchway side coamings are fitted between
detached superstructures the minimum area of the freeing port
openings shall be calculated from the following table:

The area of freeing ports at intermediate breadths shall be
obtained by linear interpolation.
(4) In ships having superstructures which are open at either
or both ends, adequate provision for freeing the space within such
superstructures shall be provided to the satisfaction of the
Administration.
(5) The lower edges of the freeing ports shall be as near the
deck as practicable. Two-thirds of the freeing port area required
shall be provided in the half of the well nearest the lowest point
of the sheer curve.
(6) All such openings in the bulwarks shall be protected by
rails or bars spaced approximately 230 millimetres (9 inches)
apart. If shutters are fitted to freeing ports, ample clearance
shall be provided to prevent jamming. Hinges shall have pins or
bearings of non-corrodible material. If shutters are fitted with
securing appliances, these appliances shall be of approved
construction.
Regulation 25
Protection of the Crew
(1) The strength of the deckhouses used for the accommodation
of the crew shall be to the satisfaction of the Administration.
(2) Efficient guard rails or bulwarks shall be fitted on all
exposed parts of the freeboard and superstructure decks. The
height of the bulwarks or guard rails shall be at least 1 metre
(39 1/2 inches) from the deck, provided that where this height
would interfere with the normal operation of the ship, a lesser
height may be approved if the Administration is satisfied that
adequate protection is provided.
(3) The opening below the lowest course of the guard rails
shall not exceed 230 millimetres (9 inches). The other courses
shall be not more than 380 millimetres (15 inches) apart. In the
case of ships with rounded gunwales the guard rail supports shall
be placed on the flat of the deck.
(4) Satisfactory means (in the form of guard rails, life
lines, gangways or underdeck passages, etc.) shall be provided for
the protection of the crew in getting to and from their quarters,
the machinery space and all other parts used in the necessary work
of the ship.
(5) Deck cargo carried on any ship shall be so stowed that any
opening which is in way of the cargo and which gives access to and
from the crew's quarters, the machinery space and all other parts
used in the necessary work of the ship, can be properly closed and
secured against the admission of water. Effective protection for
the crew in the form of guard rails or life lines shall be
provided above the deck cargo if there is no convenient passage on
or below the deck of the ship.
Regulation 26
Special Conditions of Assignment for Type "A" Ships
Machinery Casings
(1) Machinery casings on Type "A" ships as defined in
Regulation 27 shall be protected by an enclosed poop or bridge of
at least standard height, or by a deckhouse of equal height and
equivalent strength, provided that machinery casings may be
exposed if there are no openings giving direct access from the
freeboard deck to the machinery space. A door complying with the
requirements of Regulation 12 may, however, be permitted in the
machinery casing, provided that it leads to a space or passageway
which is as strongly constructed as the casing and is separated
from the stairway to the engine room by a second weathertight door
of steel or other equivalent material.
Gangway and Access
(2) An efficiently constructed fore and aft permanent gangway
of sufficient strength shall be fitted on Type "A" ships at the
level of the superstructure deck between the poop and the midship
bridge or deckhouse where fitted, or equivalent means of access
shall be provided to carry out the purpose of the gangway, such as
passages below deck. Elsewhere, and on Type "A" ships without a
midship bridge, arrangements to the satisfaction of the
Administration shall be provided to safeguard the crew in reaching
all parts used in the necessary work of the ship.
(3) Safe and satisfactory access from the gangway level shall
be available between separate crew accommodations and also between
crew accommodations and the machinery space.
Hatchways
(4) Exposed hatchways on the freeboard and forecastle decks or
on the tops of expansion trunks on Type "A" ships shall be
provided with efficient watertight covers of steel or other
equivalent material.
Freeing Arrangements
(5) Type "A" ships with bulwarks shall have open rails fitted
for at least half the length of the exposed parts of the weather
deck or other effective freeing arrangements. The upper edge of
the sheer strake shall be kept as low as practicable.
(6) Where superstructures are connected by trunks, open rails
shall be fitted for the whole length of the exposed parts of the
freeboard deck.
Chapter III. FREEBOARDS
Regulation 27
Types of Ships
(1) For the purposes of freeboard computation ships shall be
divided into Type "A" and Type "B".
Type "A" ships
(2) A type "A" ship is one which is designed to carry only
liquid cargoes in bulk, and in which cargo tanks have only small
access openings closed by watertight gasketed covers of steel or
equivalent material. Such a ship necessarily has the following
inherent features:
(a) high integrity of the exposed deck; and
(b) high degree of safety against flooding, resulting from the
low permeability of loaded cargo spaces and the degree of
subdivision usually provided.
(3) A type "A" ship, if over 150 metres (492 feet) in length,
and designed to have empty compartments when loaded to its summer
load waterline, shall be able to withstand the flooding of any one
of these empty compartments at an assumed permeability of 0.95,
and remain afloat in a condition of equilibrium considered to be
satisfactory by the Administration. In such a ship, if over 225
metres (738 feet) in length, the machinery space shall be treated
as a floodable compartment but with a permeability of 0.85.
For the guidance of Administrations the following limits may
be regarded as satisfactory:
(a) the final waterline after flooding is below the lower edge
of any opening through which progressive flooding may take place;
(b) the maximum angle of heel due to unsymmetrical flooding is
of the order of 15 degrees;
(c) the metacentric height in the flooded condition is
positive.
(4) A Type "A" ship shall be assigned a freeboard not less
than that based on Table A of Regulation 28.
Type "B" Ships
(5) All ships which do not come within the provisions
regarding Type "A" ships in paragraphs (2) and (3) of this
Regulation shall be considered as Type "B" ships.
(6) Type "B" ships, which in position 1 have hatchways fitted
with hatch covers complying with the requirements of Regulation
15 (7) or 16 shall, except as provided in paragraphs (7) to (10)
inclusive of this Regulation, be assigned freeboards based on
Table В of Regulation 28.
(7) Any Type "B" ships of over 100 metres (328 feet) in length
may be assigned freeboards less than those required under
paragraph (6) of this Regulation provided that, in relation to the
amount of reduction granted, the Administration is satisfied that:
(a) the measures provided for the protection of the crew are
adequate;
(b) the freeing arrangements are adequate;
(c) the covers in positions 1 and 2 comply with the provisions
of Regulation 16 and have adequate strength, special care being
given to their sealing and securing arrangements;
(d) the ship, when loaded to its summer load waterline, will
remain afloat in a satisfactory condition of equilibrium after
flooding of any single damaged compartment at an assumed
permeability of 0.95 excluding the machinery space; and
(e) in such a ship, if over 225 metres (738 feet) in length,
the machinery space shall be treated as a floodable compartment
but with a permeability of 0.85.
For the guidance of Administrations in applying sub-paragraphs
(d) and (e) of this paragraph the limits given in sub-paragraphs
(3) (a), (b) and (c) may be regarded as satisfactory.
The relevant calculations may be based upon the following main
assumptions:
- the vertical extent of damage is equal to the depth of the
ship;
- the penetration of damage is not more than B/5;
- no main transverse bulkhead is damaged;
- the height of the centre of gravity above the base line is
assessed allowing for homogeneous loading of cargo holds, and for
50 per cent of the designed capacity of consumable fluids and
stores, etc.
(8) In calculating the freeboards for Type "B" ships which
comply with the requirements of paragraph (7) of this Regulation,
the values from Table B of Regulation 28 shall not be reduced by
more than 60 per cent of the difference between the "B" and "A"
tabular values for the appropriate ship lengths.
(9) The reduction in tabular freeboard allowed under paragraph
(8) of this Regulation may be increased up to the total difference
between the values in Table A and those in Table B of Regulation
28 on condition that the ship complies with the requirements of
Regulation 26 (1), (2), (3), (5) and (6), as if it were a type "A"
ship, and further complies with the provisions of paragraph (7)
(a) to (d) inclusive of this Regulation except that the reference
in sub-paragraph (d) to the flooding of any single damaged
compartment shall be treated as a reference to the flooding of any
two adjacent fare and aft compartments, neither of which is the
machinery space. Also any such ship of over 225 metres (738 feet),
in length, when loaded to its slimmer "load waterline, shall
remain afloat in a satisfactory condition of equilibrium after
flooding of the machinery space, taken alone, at an assumed
permeability of 0.85.
(10) Type "B" ships, which in position 1 have hatchways fitted
with hatch covers which comply with the requirements of Regulation
15, other than paragraph (7), shall be assigned freeboards based
upon the values given in Table B of Regulation 28 increased by the
values given in the following table:
Freeboard increase over tabular freeboard for type "B" ships,
for ships with hatch covers not complying with Regulation 15 (7)

Regulation 31
Correction for Depth
(1) Where D exceeds L/15 the freeboard shall be increased by
(D - L/15) R millimetres, where R is L/0.48 at lengths less than
120 metres and 250 at 120 metres length and above, or (D - L/15) R
inches, where R is L/131.2 at lengths less than 393.6 feet and 3
at 393.6 feet length and above.
(2) Where D is less than L/15 no reduction shall be made
except in a ship with an enclosed superstructure covering at least
0.6 L amidships, with a complete trunk, or combination of detached
enclosed superstructures and trunks which extend all fore and aft,
where the freeboard shall be reduced at the rate prescribed in
paragraph (1) of this Regulation.
(3) Where the height of superstructure or trunk is less than
the standard height, the reduction shall be in the ratio of the
actual to the standard height as defined in Regulation 33.
Regulation 32
Correction for Position of Deck Line
Where the actual depth to the upper edge of the deck line is
greater or less than D, the difference between the depths shall be
added to or deducted from the freeboard.
Regulation 33
Standard Height of Superstructure
The standard height of a superstructure shall be as given in
the following table:
Standard Height (in metres)
-------------------------T--------------------T------------------¬
