In these case where bottom damage
simultaneously involves four centre tanks, the value of Os may be
calculated according to the formula:

where:
Wi : volume of a wing tank in m3 assumed to be
breached by the damage as specified in (1); Wi for a segregated
ballast tank may be taken equal to zero;

Zi = 1− hi / vs
When bi is equal to or
greater than vs, zi shall be taken equal to zero.
bi : width of wing tank in m under consideration measured
inboard from the ship's side at right angles to the centerline at the level
corresponding to the assigned summer freeboard;
hi : minimum depth of the double bottom in m under
consideration; where no double bottom is fitted hi shall be taken equal to
zero.
(b) If a void space or segregated
ballast tank of a length less than lc as defined in (1) is
located between wing oil tanks, Oc in formula (I) under (a)(i) may
be calculated on the basis of volume Wi being the actual volume of
one such tank (where they are of equal capacity) or the smaller of the two
tanks (if they differ in capacity) adjacent to such space, multiplied by Si
as defined below and taking for all other wing tanks involved in such collision
the value of the actual full volume:

(i) Credit shall only be given in
respect of double bottom tanks which are either empty or carrying clean water
when cargo is carried in the tanks above;
(ii) Where the double bottom does
not extend for the full length and width of the tank involved, the double
bottom is considered non-existent and the volume of the tanks above the area of
the bottom damage shall be included in formula (II) or (iii) under (a)(ii) even
if the tank is not considered breached because of the installation of such a
partial double bottom;
(iii) Suction wells may be
neglected in the determination of the value hi provided such wells
are not excessive in area and extend below the tank for a minimum distance and
in no case more than half the height of the double bottom. If the depth of such
a well exceeds half the height of the double bottom, hi shall be taken equal to
the double bottom height minus the well height. Piping serving such wells if
installed within the double bottom shall be fitted with valves or other closing
arrangements located at the point of connection to the tank served to prevent
oil outflow in the event of damage to the piping. Such piping shall be
installed as high from the bottom shell as possible.
(3) Cargo tanks of oil tankers
shall be of such size and arrangements that the hypothetical outflow Oc
or Os calculated in accordance with the provisions of (2) anywhere
in the length of the ship does not exceed 30,000 m3 or 400
, whichever is the
greater, but subject to a maximum of 40,000 m3. However, where
equipment capable of moving oil from breached tanks or fuel tanks to segregated
ballast tanks or cargo tanks with significant ullage is installed and such
cargo tanks are outfitted with high emergency suction equipment, formula (III)
under (2) may be applied.
Such equipment must be capable of
moving oil quantity equivalent to half the volume of the largest tanks among
the breached tanks for 2 hours of operation and the receiving ballast tanks or
cargo tanks must be capable of receiving such oil quantity. Piping serving high
emergency suction equipment must be installed at a height greater than vertical
distance of location of bottom damage.
(4) Individual cargo tanks must not
exceed the following dimensions:
(a) Volume of a wing cargo tank in
oil tanker must not exceed 75% the hypothetical outflow mentioned under (3).
Volume of a center cargo tank must not exceed 50.000 m3. However,
where oil tankers are outfitted with segregated ballast tanks under 3.2.3,
permissible volume of wing cargo tanks located between segregated ballast
tanks, the length of each of which exceeds lc, can be
increased up to the upper limit of the hypothetical outflow as long as width of
wing tanks exceeds tc;
(b) The length of each cargo tank
must not exceed 10 m or any of the following value, whichever is greater:

“bn” is the minimum
distance from the ship's side to the outer longitudinal bulkhead of the tank in
question measured inboard at right angles to the centerline at the level
corresponding to the assigned summer freeboard.
(5) In order not to exceed the
volume limits established by (3) and (4) and irrespective of the accepted type
of cargo transfer system installed, when such system interconnects two or more
cargo tanks, valves or other similar closing devices shall be provided for
separating the tanks from each other;
(6) Lines of piping which run
through cargo tanks in a position less than tc from the ship's side or less
than vs from the ship's bottom shall be fitted with valves or
similar closing devices at the point at which they open into any cargo tank.
These valves and closing devices must conform to requirements (i) and (ii)
below. Each valve in branching suction pipe (valves marked with “*1” in Figure
3.3.2) generally must be installed in each open compartment (inside each tank)
(with the exceptions detailed under Figure 3.3.3). However, where placement and
installation of the valves deemed equivalent to the aforementioned requirement
are implemented to prevent further spread of outflow caused by breach of cargo
tanks, the valves marked with “*2” in Figure 3.3.2 may be outfitted inside
adjacent tanks. Where a valve is installed inside adjacent tanks, the valve
must be installed towards the longitudinal bulkhead side of a line that creates
a 45o angle with the bottom.
(i) For the purpose of restricting
the hypothetical outflow and stabilizing incidents, such installation
requirement applies even when valve is not required to prevent acceleration of
outflow;
(ii) Valves are not required in
respective tanks in examples 1 and 2 below:
Example 1: Where pipe passes through
tanks outside of the damage radius (Figure 3.3.3).
Example 2: In case arrangement
depicted under Figure 3.3.4 is used in ore-bulk-oil combination carrier, where
durability and thickness of pipe segments penetrating the bulkhead equal those
of the bulkhead and the length is of minimum according to valve installation
requirement (Figure 3.3.4).

1 All oil tankers must meet subdivision and damage
stability requirements under 3.2.2-3 after the assumed side or bottom damage as
specified in 3.2.2-2, for any operating draft reflecting actual partial or full
load conditions consistent with trim and strength of the ship as well as
relative densities of the cargo. Such damage shall be applied to all conceivable locations
along the length of the ships as detailed under (1) through (3) below:
(1) in tankers of more than 225 m
in length: anywhere in the ship's length;
(2) in tankers of more than 150 meters,
but not exceeding 225 m in length: anywhere in the ship's length except
involving either after or forward bulkhead bounding the machinery space located
aft. Machinery space shall be treated as a single floodable compartment;
(3) in tankers not exceeding 150 m
in length: anywhere in the ship's length between adjacent transverse bulkheads
with the exception of the machinery space. For tankers of 100 meters or less in
length where all requirements of 3.2.2-3 cannot be fulfilled without materially
impairing the operational qualities of the ship, VR may allow relaxations from
these requirements. Ballast conditions where the tanker is not carrying oil in
cargo tanks, excluding any oil residues, shall not be considered.
2 The following provisions regarding the extent and
characteristics of the assumed damage shall apply:
(1) Side damage extent under
Schedule 3.9;
(2) Bottom damage extent under Schedule
3.10. However, in respect of oil tankers with minimum deadweight of 20.000
tonne, the assumed damage under Schedule 3.10 must be complemented by assumed
damage to bottom shell plating in accordance with Schedule 3.11;
(3) If any damage of a lesser
extent than the maximum extent of damage specified in (1) and (2) would result
in a more severe condition, such damage shall be considered;
(4) Where the damage involving
transverse bulkheads is envisaged as specified in 3.2.2-1(1), transverse
watertight bulkheads shall be spaced at least at a distance equal to the
longitudinal extent of assumed damage specified in (1) in order to be
considered effective. Where transverse bulkheads are spaced at a lesser
distance, one or more of these bulkheads within such extent of damage shall be
assumed as non-existent for the purpose of determining flooded compartments;

(a) the spacing of the adjacent
bulkheads is less than the longitudinal extent of assumed damage specified in
(1); or
(b) there is a step or recess in a
transverse bulkhead of more than 3,05 m in length, located within the extent of
penetration of assumed damage. In this provision, the step formed by the after
peak bulkhead and after peak top shall not be regarded as a step for the
purpose of requirement under 3.3.2.
(6) If pipes, ducts or tunnels are
situated within the assumed extent of damage, arrangements shall be made so
that progressive flooding cannot thereby extend to compartments other than
those assumed to be floodable for each case of damage.
3 Oil tankers shall be regarded as complying with the
damage stability criteria if the requirements under (1) through (5) are met:
(1) The final waterline, taking
into account sinkage, heel and trim, shall be below the lower edge of any
opening through which progressive flooding may take place. Such openings shall
include air-pipes and those which are closed by means of weathertight doors or
hatch covers and may exclude those openings closed by means of watertight
manhole covers and flush scuttles, small watertight cargo tank hatch covers
which maintain the high integrity of the deck, remotely operated watertight
sliding doors, and sidescuttles of the non-opening type;

* : Permeabilities of a partially flooded
space must depend on the amount of liquid occupied said space. In case of
damage to any liquid tank, it is assumed that all liquid in that tank will be
replaced by saltwater up to the last stable surface.
(3) The buoyancy of any
superstructure directly above the side damage should be disregarded. The
unflooded parts of superstructures beyond the extent of damage, however, may be
taken into consideration provided that they are separated from the damaged
space by watertight divisions and the requirements of 3.2.2-3(1) in respect of
these intact spaces are complied with. Hinged watertight doors can be accepted
as watertight divisions in the superstructures;
(4) The effect of free surfaces
shall be taken into account at an angle of 5o for individual divisions.
VR may request or permit free surface correction determined at an angle greater
than 5o in respect of partially flooded tanks;
(5) For the purpose of calculating
clear surface effects of consumable liquid, it should be assumed that for each
type of liquid at least one transverse pair or a single centerline tank has a
free surface and the tank or combination of tanks taken into account should be
those where the effect of free surfaces is the greatest.

handling and distribution satisfies provisions under 3.2.2; and
(2) Data pertaining to ship’s
ability to meet damage stability conforms to 3.2.2, including results of
exemptions permitted under 3.2.2-1(3).
6 Oil tankers of at least 5,000 tonnes deadweight must
meet intact stability below in the most unfavorable conditions of cargo and
ballast during transport of liquid cargo. Liquid cargo transport mentioned under -6 and -7 includes
activities transporting liquid cargo implemented on board such as
filling/removing cargo, relocating cargo, ballasting/de-ballasting, relocating
ballast water, and washing tank. However, this does not include asymmetrical
ballasting/cargo loading if the ship is outfitted with longitudinal partitions,
all tanks on one side are empty while all tanks on the other side are
partially/completely full.
