INTERNATIONAL CONVENTION FOR THE PREVENTION OF
POLLUTION FROM SHIPS, 1973
London, 2 November 1973
The Parties to the Convention,
Being conscious of the need to preserve the human environment
in general and the marine environment in particular,
Recognizing that deliberate, negligent or accidental release
of oil and other harmful substances from ships constitutes a
serious source of pollution,
Recognizing also the importance of the International
Convention for the Prevention of Polution of the Sea by Oil,
1954, as being the first multilateral instrument to be
concluded with the prime objective of protecting the
environment, and appreciating the significant contribution
which that Convention has made in preserving the seas and
coastal environment from pollution,
Desiring to achieve the complete elimination of intentional
pollution of the marine environmewhatnt by oil and other harmful
substances and the minimization of accidental discharge of
such substances,
Considering that this object may best be achieved by
establishing rules not limited to oil pollution having a
universal purport,
Have agreed as follows:
Article 1
GENERAL OBLIGATIONS UNDER THE CONVENTION
1 The Parties to the Convention undertake to give effect to
the provisions of the present Convention and those Annexes
thereto by which they are bound, in order to prevent the
pollution of the marine environment by the discharge of
harmful substances or effluents containing such substances in
contravention of the Convention.
2. Unless expressly provided otherwise, a referrence to the
present Convention constitutes at the same time a reference
to its Protocol and to the Annexes.
Article 2
DEFINITIONS
For the purposes of the present Convention, unless expressly
provided otherwise:
1. "Regulations" means the Regulations contained in the
Annexes to the present Convention
2. "Harmful substance" means any substance which, if
introduced into the sea, is liable to create hazards to human
health, to harm living resources and marine life, to damage
amenities or to interfere with other legitimate uses of the
sea, and includes any substance subject to control by the
present Convention.
3. a) "Discharge", in relation to harmful substances or
effluents containing such substances, means any release
howsoever caused from a ship and includes any escape,
disposal, spilling, leaking, pumping, emitting or emptying;
b) "Discharge" does not include:
(i) dumping within the meaning of the Convention on the
Prevention of Marine Pollution by Dumping of Wastes and Other
Matter, done at London on 13 November 1972; or
(ii) release of harmful substances directly arising from the
exploration, exploitation and associated off-shore processing
of sea-bed mineral resources; or
(iii) release of harmful substances for purpose of legitimate
scientific research into pollution abatement or control.
4. "Ship" means a vessel of any type whatsoever operating in
the marine environment and includes hydrofoil boats, air-
cushion vehicles, submersibles, floating craft and fixed or
floating platforms.
5. "Administration" means the Government of the State under
whose authority the ship is operating. With respect to a ship
entitled to fly a flag of any State, the Administration is
the Government of that State. With respect to fixed or
floating platforms engaged in exploration and exploitation of
the sea-bed and subsoil thereof adjacent to the coast over
which the coastal State exercises sovereign rights for the
purposes of exploration and exploitation of their natural
resources, the Administration is the Government of the
coastal State concerned.
6. "Incident" means an event involving the actual or probable
discharge into the sea of a harmful substance, or effluents
containing such a substance.

Consultative Organization.
Article 3
APPLICATION
1. The present Convention shall apply to:
a) ships entitled to fly the flag of a Party to the
Convention; and
b) ships not entitled to fly the flag of a Party but which
operate under the authority of a Party.
2. Nothing in the present Article shall be construed as
derogating from or extending the sovereign rights of the
Parties under international law over the sea-bed and subsoil
thereof adjacent to their coasts for the purposes of
exploration and exploitation of their natural resources.
3. The present Convention shall not apply to any warship,
naval auxiliary or other ship owned or operated by a State
and used, for the time being only on government non-
commercial service. However, each Party shall ensure by the
adoption of appropriate measures not impairing the operations
or operational capabilities of such ships owned or operated
by it, that such ships act in a manner consistent, so far as
is reasonable and practiable, with the present Convention.
Article 4
VIOLATION
1. Any violation of the requirements of the present
Convention shall be prohibited and sanctions shall be
established therefor under the law of the Administration of
the ship concerned wherever the violation occurs. If the
Adminsitration is informed of such a violation and is
satisfied that sufficient evidence is available to enable
proceedings to be brought in respect of the alleged
violation, it shall cause such proceedings to be taken as
soon as possible, in accordance with its law.
2. Any violation of the requirements of the present
Convention within the jurisdiction of any Party to the
Convention shall be prohibited and sanctions shall be
established therefore under the law of that Party. Whenever
and violation occurs, the Party shall either:
a) cause proceedings to be taken in accordance with its law;
or
b) furnish to the Administration of the ship such information
and evidence as may be in its possession that a violation has
occurred.
3. Where information or evidence with respect to any
violation of the present Convention by a ship is furnished to
the Administration of that ship, the Administration shall
promptly inform the Party which has furnished the information
or evidence and the Organization, of the action taken.
4. The penalties specified under the law of a Party pursuant
to the present Article shall be adequate in severity to
discharge violations of the present Convention and shall be
equally severe irrespective of where the violations occur.
Article 5
CERTIFICATES AND SPECIAL RULES ON INSPECTION OF SHIPS
1. Subject to the provisions of paragraph (2) of the present
Article a certificate issued under the authority of a Party
to the Convention in accordance with the provisions of the
Regulations shall be accepted by the other Parties and
regarded for all purposes covered by the present Convention
as having the same validity as a certificate issued by them.
2. A ship required to hold a certificate in accordance with
the provisions of the Regulations is subject, while in the
ports or off-shore terminals under the jurisdiction of a
Party, to inspection by officers duly authorized by that
Party. Any such inspection shall be limited to verfying that
there is on board a valid certificate, unless there are clear
grounds for believing that the condition of the ship or its
equipment does not correspond substantially with the
particulars of that certificate. In that case, or if the ship
does not carry a valid certificate the Party carrying out the
inspection shall take such steps as will ensure that the ship
shall not sail until it can proceed to sea without presenting
an unreasonable threat of harm to the marine environment.
That Party may, however, grant such a ship permission to
leave the port or off-shore terminal for the purpose of
proceedings to the nearest appropriate repair yard available.
3. If a Party denies a foreign ship entry to the ports or
off-shore terminals under its jurisdiction or takes any
action against such a ship for the reason that the ship does
not comply with the provisions of the present Convention, the
Party shall immediately inform the consul or diplomatic
representative of the Party whose flag the ship is entitled
to fly, or if this is not possible, the Administration of the
ship concerned. Before denying entry or taking such action
the Party may request consultation with the Administration of
the ship concerned. Information shall also be given to the
Administration when a ship does not carry a valid certificate
in accordance with the provisions of the Regulations.
4. With respect to the ships of non-Parties to the
Convention, Parties shall apply the requirements of the
present Convention as may be necessary to ensure that no more
favourable treatment is given to such ships.
Article 6
DETECTION OF VIOLATIONS AND ENFORCEMENT OF THE CONVENTION
1. Parties to the Convention shall co-operate in the
detection of violations and the enforcement of the provisions
of the present Convention, using all appropriate and
practicable measures of detection and environmental
monitoring, adequate procedures for reporting and
accumulation of evidence.
2. A ship to which the present Convention applies may, in any
port or off-shore terminal of a Party, be subject to
inspection by officers appointed or authorized by that Party
for the purpose of verifying whether the ship has discharged
any harmful substances in violation of the provisions of the
Regulations. If an inspection indicates a violation of the
Convention, a report shall be forwarded to the Administration
for any appropriate action.
3. Any Party shall furnish to the Administration evidence, if
any, that the ship had discharged harmful substances in
violation of the provisions of the Regulations. If it is
practicable to do so, the competent authority of the former
Party shall notify the Master of the ship of the alleged
violation.
4. Upon receiving such evidence, the Administration so
informed shall investigate the matter, and may request the
other Party to furnish further or better evidence of the
alleged contravention. If the Administration is satisfied
that sufficient evidence is available to enable proceedings
to be brought in respect of the alleged violation, it shall
cause such proceedings to be taken in accordance with its law
as soon as possible. The Administration shall promptly inform
the Party which has reported the alleged violation, as well
as the Organization, of the action taken.
5. A Party may also inspect a ship to which the present
Convention applies when it enters the ports or off-shore
terminals under its jurisdiction, if a request for an
investigation is received from any Party together with
sufficient evidence that the ship has discharged harmful
substances or effluents containing such substances in any
place. The report of such investigation shall be sent to the
Party requesting it and to the Administration so that the
appropriate action may be taken under the present Convention.
Article 7
UNDUE DELAY TO SHIPS

unduly detained or delayed under Article 4, 5, or 6 of the
present Convention.

2. a) Adequate means shall be provided for cleaning the cargo
tanks and transferring the dirty ballast residue and tank
washings from the cargo tanks into a slop tank approved by
the Administration. In existing oil tankers, any cargo tank
may be designated as a slop tank.
b) In this system arrangements shall be provided to transfer
the oily waste into a slop tank or combination of slop tanks
in such a way that any effluent discharged into the sea will
be such as to comply with the provisions of Regulation 9 of
this Annex.
c) The arrangements of the slop tank or combination of slop
tanks shall have a capacity necessary to retain the slops
generated by tank washing, oil residues and dirty ballast
residues but the total shall be not less than 3 per cent of
the oil carrying capacity of the ship, except that, where
segregated ballast tanks are provided in accordance with
Regulation 13 of this Annex, or where arrangements such as
eductors involving the use of water additional to the washing
water are not fitted, the Administration may accept 2 per
cent. New oil tankers over 70,000 tons deadweight shall be
provided with at least two slop tanks.
d) Slop tanks shall be designed particularly in respect of
the position of inlets, outlets, baffles or where fitted, so
as to avoid excessive turbulence and entrainment of oil or
emulsion with the water.
3. a) An oil discharge monitoring and control system approved
by the Administration shall be fitted. In considering the
design of the oil content meter to be incorported in the
system, the Administration shall have regard to the

operation when there is any discharge of effluent into the
sea and shall be such as will ensure that any discharge of
oily mixture is automatically stopped when the instantaneous
rate of discharge of oil exceeds that permitted by Regulation
9(1)(a) of this Annex. Any failure of this monitoring and
control system shall stop the discharge and be noted in the
Oil Record Book. A manually operated alternative method shall
be provided and may be used in the event of such failure, but
the defective unit shall be made operable before the oil
tanker commences its next ballast voyage unless it is
proceeding to a repair port. Existing oil tankers shall
comply with all of the provisions specified above except that
the stopping of the discharge may be performed manually and
the rate of discharge may be estimated from the pump
characteristic.
b) Effective oil/water interface detectors approved by the
Administration shall be provided for a rapid and accurate
determination of the oil/water interface in slop tanks and
shall be available for use in other tanks where the
separation of oil and water is effected and from which it is
intended to discharge effluent direct to the sea.
c) Instructions as to the operation of system shall be in
accordance with an operational manual approved by the
Administration. They shall cover manual as well as automatic
operations and shall be intended to ensure that at no time
shall oil be discharged except in compliance with the
conditions specified in Regulation 9 of this Annex.*
* Reference is made to the Recommendation on International
Performance Specifications for Oily-Water Separating
Equipment and Oil Content Meters adopted by the Organization
by Resolution A.233 (VII).
4. The requirements of paragraphs (1), (2) and (3 ) of this
Regulation shall not apply to oil tankers of less than 150
tons gross tonnage, for which the control of discharge of oil
under Regulation 9 of this Annex shall be effected by the
retention of oil on board with subsequent discharge of all
contaminated washings to reception facilities. The total
quantity of oil and water used for washing and returned to a
storage tank shall be recorded in the Oil Record Book. This
total quantity shall be discharged to reception facilities
unless adequate arrangements are made to ensure that any
effluent which is allowed to be discharged into the sea is
effectively monitored to ensure that the provision of
Regulation 9 of this Annex are complied with.
5. The Administration may waive the requirements of
paragraphs (1), (2) and (3) of this Regulation for any oil
tanker which engages exclusively on voyages both of 72 hours
or less in duration and within 50 miles from the nearest
land, provided that the oil tanker is not required to hold
and does not hold an International Oil Pollution Prevention
Certificate (1973). Any such waiver shall be subject to the
requirements that the oil tanker shall retain on board all
oily mixtures for subsequent discharge to reception
facilities and to the determination by the Administration
that facilities available to receive such oily mixtures are
adequate.
6. Where in the view of the Organization equipment required
by Regulation 9(1)(a)(vi) of this Annex and specified in sub-
paragraph (3)(a) of this Regulation is not obtainable for the
monitoring of discharge of light refined products (white
oils), the Administration may waive compliance with such
procedures established by the Organization which shall
satisfy the conditions of Regulation 9(1)(a) of this Annex
except the obligation to have an oil discharge monitoring and
control system in operation. The Organization shall review
the availability of equipment at intervals not exceeding
twelve months.
7. The requirements of paragraphs (1), (2) and (3) of this
Regulation shall not apply to oil tankers carrying asphalt,
for which the control of discharge of asphalt under
Regulation 9 of this Annex shall be effected by the retention
of asphalt residues on board with discharge of all
contaminated washings to reception facilities.

Chapter III
REQUIREMENTS FOR MINIMIZING OIL POLLUTION FROM OIL TANKERS
DUE TO SIDE AND BOTTOM DAMAGES
Regulation 22
DAMAGE ASSUMPTIONS
1. For the purpose of calculating hypothetical oil outflow
from oil tankers, three dimensions of the extent of damage of
a parallelepiped on the side and bottom of the ship are
assumed as follows. In the case of bottom damages two
conditions are set forth to be applied individually to the
stated portions of the oil tanker.
a) Side damage
(i) Longitudinal 1/3 L 2/3 or 14.5 metres,
extent (lc); whichever is less
(ii) Transverse B/5 or 11.5 metres,
extent (lc): whichever is less
(inboard from the
ship's side at right
angles to the
centre-line at the
level correspond-
ing to the assigned
summer freeboard)
(iii) Vertical from the base line
extent (vc): upwards without limit
b) Bottom damage
For 0.3L from Any other part
the forward of the ship
perpendicular
of the ship
(i) Long- L/10 L/10 or 5 metres,
itudinal whichever is less
extent (ls)
(ii) Trans- B/6 or 10 metres, 5 metres
verse whichever is less but not less
extent than 5 metres
(ts)
(iii) Vertical B or 6 metres,
extent
from the whichever is less
base
line (vs):
2. Whenever the symbols given in this Regulation
appear in this Chapter, they have the meaning as
defined in this Regulation.
Regulation 23
HYPOTHETICAL OUTFLOW OF OIL
1. The hypothetical outflow of oil in the case of side damage
(Oc) and bottom damage (Os) shall be calculated by the
following formulae with respect to compartments breached by
damage to all conceivable locations along the length of the
ship to the extent as defined in Regulation 22 of this Annex.
a) for side damages:
Oc = sigmaW1 + sigmaK1C1 (I)
b) for bottom damages:
Os = 1/3(sigmaZ1W1 + sigmaZ1C1) (II)
where:
Wi = volume of a wing tank in cubic metres assumed to be
breached by the damage as specified in Regulation 22 of
this Annex; Wi for a segregated ballast tank may be
taken equal to zero.
Ci = volume of a centre tank in cubic metres assumed to be
breached by the damage as specified in Regulation 22 of
this Annex; Ci for a segregated ballast tank may be
taken equal to zero.
Ki = 1 - bi/tc when bi is equal to or greater than
tc, Ki shall be taken equal to zero,
Zi = 1 - hi/vs when hi is equal to or greater than vs, Zi
shall be taken equal to zero,
bi= width of wing tank in metres under consideration measured
inboard from the ship's side at right angles to the
centreline at the level corresponding to the assigned
summer freeboard,
hi = minimum depth of the double bottom in metres under
consideration; where no double bottom is fitted hi shall
be taken to be equal to zero.
Whenever symbols given in this paragraph appear in the
Chapter, they have the meaning as defined in this Regulation.
2. If a void space or segregated ballast tank of a length
less than lc as defined in Regulation 22 of
this Annex is located between wing oil tanks, Oc in formula
(1) 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 a
collision the value of the actual full volume.
Si = 1 - li/lc
where li = length in metres of void space or segregated
ballast tank under consideration.
3. a) 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.
b) Where the double bottom does not extent 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)
even if the tank is not considered breached because of the
installation of such a partial double bottom.
c) 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 connextion 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. These valves shall be kept closed
at sea at any time when the tank contains oil cargo, except
that they may be opened only for cargo transfer needed for
the purpose of trimming of the ship.
4. In the case where bottom damage simultaneously involves
four centre tanks, the value of Os may be calculated
according to the formula
Os = 1/4(sigmaZiWi + sigmaZiCi) (III)
5. An Administration may credit as reducing oil outflow in
case of bottom damage, an installed cargo transfer system
having an emergency high suction in each cargo oil tank,
capable of transferring from a breached tank or tanks to
segregated ballast tanks or to available cargo tankage if it
can be assured that such tanks will have sufficient ullage.
Credit for such a system would be governed by ability to
transfer in two hours of operation oil equal to one half of
the largest of the breached tanks involved and by
availability of equivalent receiving capacity in ballast or
cargo tanks. The credit shall be confined to permitting
calculation of Os according to formula (III). The pipes for
such suctions shall be installed at least at a height not
less than the vertical extent of the bottom damage vs. The
Administration shall supply the Organization with the
information concerning the arrangements accepted by it, for
circulation to other Parties to the Convention.
Regulation 24
LIMITATION OF SIZE AND ARRANGEMENT OF CARGO TANKS
1. Every new oil tanker shall comply with the provision of
this Regulation. Every existing oil tanker shall be required,

or
b) a tanker to which both the following conditions apply:
(i) delivery is not later than 1 January 1977; and
(ii) the building contract is placed after 1 January 1974, or
in cases where no building contract has previously been
placed, the keel is laid or the tanker is at a similar stage
of construction after 30 January 1974.
2. 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 Regulation 23
of this Annex anywhere in the length of the ship does not
exceed 30,000 cubic metres or 400 x cube root of DW,
whichever is the greater, but subject to a maximum of 40,000
cubic metres.
3. The volume of any one wing cargo oil tank of an oil tanker
shall not exceed seventy-five per cent of the limits of the
hypothetical oil outflow referred to in paragraph (2) of this
Regulation. The volume of any one centre cargo oil tank shall
not exceed 50,000 cubic metres. However, in segregated
ballast oil tankers as defined in Regulation 13 of this
Annex, the permitted volume of a wing cargo oil tank situated
between two segregated ballast tanks, each exceeding lc in
length, may be increased to the maximum limit of hypothetical
oil outflow provided that the width of the wing tanks exceeds
tc.
4. The length of each cargo tank shall not exceed 10 metres
or one of the following values, whichever is the greater:
a) where no longitudinal bulkhead is provided:
0.1L
b) where a longitudinal bulkhead is provided at the
centreline only:
0.15L
c) where two or more longitudinal bulkheads are provided:
(i) for wing tanks:
0.2L
(ii) for centre tanks:
(1) if bi B is equal to or greater than 1/5:
0.2L B
(2) if bi/B is less than 1/5:
where no centreline longitudinal bulkhead is
provided:
(0.5 bi/B + 0.1)L

5. In order not to exceed the volume limits established by
paragraphs (2), (3) and (4) of this Regulation and
irrespective of the accepted type of cargo transfer system
installed, when such a system inter-connects two or more
cargo tanks, valves or
other similar closing devices shall be provided for
separating the tanks from each other. These valves or devices
shall be closed when the tanker is at sea.
6. Lines of piping which run through cargo tanks
in a position less than tc from the ship's side or less than
vc 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 shall be kept closed at sea at
any time when the tanks contain cargo oil, except that they
may be opened only for cargo transfer needed for the purpose
of trimming of the ship.
Regulation 25
SUBDIVISION AND STABILITY
1. Every new oil tanker shall comply with the subdivision and
damage stability criteria as specified in paragraph (3) of
this Regulation, after the assumed side or bottom damage as
specified in paragraph (2) of this Regualtion, for any
operating draught reflecting actual partial or full load
conditions consistent with trim and strength of the ship as
well as specific gravities of the cargo. Such damage shall be
applied to all conceivable locations along the length of the
ship as follows:
a) in tankers of more than 225 metres in length, anywhere in
the ship's length;
b) in tankers of more than 150 metres, but not exceeding 225
metres in length, anywhere in the ship's length except
involving either after or forward bulkhead bounding the
machinery space located aft. The machinery space shall be
treated as a single floodable compartment;
c) in tankers not exceeding 150 metres in length,
anywhere in the ship's length between adjacent transverse
bulkheads with the exception of the machinery space. For
tankers of 100 metres or less in length where all
requirements of paragraph (3) of this Regulation cannot be
fulfilled without materially impairing the operational
qualities of the ship, Administrations 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 the
character of the assumed damage shall apply:
a) The extent of side or bottom damage shall be as specified
in Regulation 22 of this Annex, except that the longitudinal
extent of the bottom damage within 0.3L from the forward
perpendicular shall be the same as for side damage, as
specified in Regulation 22 (1)(a)(i) of this Annex. If any
damage of lesser extent results in a more severe condition
such damage shall be assumed.
b) Where the damage involving transverse bulkheads is
envisaged as specified in subparagraphs (1)(a) and (b) of
this Regulation, transverse watertight bulkheads shall be
spaced at least at a distance equal to the longitudinal
extent of assumed damage specified in sub-paragraph (a) of
this paragraph 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.
c) Where the damage between adjacent transverse watertight
bulkheads is envisaged as specified in sub-paragraph (1)(c)
of this Regulation, no main transverse bulkhead or a
transverse bulkhead bounding side tanks or double bottom
tanks shall be assumed damaged, unless:
(i) the spacing of the adjacent bulkheads is less than the
longitudinal extent of assumed damage specified in sub-
paragraph (a) of this paragraph; or
(ii) there is a step or a recess in a transverse bulkhead of
more than 3.05 metres in length, located within the extent of
penetration of assumed damage. The step forward by the after
peak bulkhead and after peak tank top shall not be regarded
as a step for the purpose of this Regulation.
d) 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 following requirements are met:
a) 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 side scuttles of the
non-opening type,
b) In the final stage of flooding, the angle of heel due to
unsymmetrical flooding shall not exceed 25 degrees, provided
that this angle may be increased up to 30 degrees if no deck
edge immersion occurs.
c) The stability in the final stage of flooding shall be
investigated and may be regarded as sufficient if the
righting lever curve has at least a range of 20 degrees
beyond the position of equilibrium in association with a
maximum residual righting lever of at least 0.1 metre. The
Administration shall give consideration to the potential
hazard presented by protected or unprotected openings which
may become temporarily immersed within the range of residual
stability.
d) The Administration shall be satisfied that the stability
is sufficient during intermediate stages of flooding.
4. The requirements of paragraph (1) of this Regulation shall
be confirmed by calculations which take into consideration
the design characteristics of the ship, the arrangements,
configuration and contents of the damaged compartments; and
the distribution, specific gravities and the free surface
effect of liquids. The calculations shall be based on the
following:
a) Account shall be taken of any empty or partially filled
tank, the specific gravity of cargoes carried, as well as any
outflow of liquids from damaged compartments.
b) The permeabilities are assumed as follows:
Spaces Permeability
Appropriated to 0.60
stores
Occupied by 0.95
accommodation
Occupied by machinery 0.85
Voids 0.95
Intended for 0 to 0.95*
consumable liquids
Intended for 0 to 0.95**
other liquids
* Whichever results in the more severe requirements.
** The permeability of partially filled compartments shall be
consistent with the amount of liquid carried.
c) The buoyancy of any superstructure directly above the side
damage shall 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 bulkheads and the
requirements of sub-paragraph (3)(a) of this Regulation in
respect of these intact spaces are complied with. Hinged
watertight doors may be acceptable in watertight bulkheads in
the superstructure.
d) The free surface effect shall be calculated at an angle of
heel of 5 degrees for each individual compartment. The
Administration may require or allow the free surface
corrections to be calculated at an angle of heel greater than
5 degrees for partially filled tanks.
e) In calculating the effect of free surfaces of consumable
liquids it shall be assumed that, for each type of liquid at
least one transverse pair or a single centreline tank has a
free surface and the tank or combination of tanks to be taken
into account shall be those where the effect of free surfaces
is the greatest.
5. The Master of every oil tanker and the person in charge of
a non-self-propelled oil tanker to which this Annex applies
shall be supplied in an approved form with:
a) information relative to loading and distribution of cargo
necessary to ensure compliance with the provisions of this
Regulation; and
b) data on the ability of the ship to comply with damage
stability criteria as determined by this Regulation,
including the effect of relaxations that may have been
allowed under sub-paragraph (1)(c) of this Regulation.
