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 environment 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.

7. "Organization" means the Inter-Governmental Maritime 
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

1. All possible efforts shall be made to avoid a ship being 
unduly detained or delayed under Article 4, 5, or 6 of the 
present Convention.

2. When a ship is unduly detained or delayed under Article 4, 
5, 6 of the present Convention, it shall be entitled to 
compensation for any loss or damage suffered.


Article 8 

REPORTS ON INCIDENTS INVOLVING HARMFUL SUBSTANCES

1. A report of an incident shall be made without delay to the 
fullest extent possible in accordance with the provisions of 
Protocol I to the present Convention.

or agency to receive and process all reports on incidents; 
and

b) notify the Organization with complete details of such 
arrangements for circulation to other Parties and Member 
States of the Organization.

the present Article, the Party shall relay the report without 
delay to:

b) any other State which may be affected.

4. Each Party to the Convention undertakes to issue 
instructions to its maritime inspection vessels and aircraft 
and to other appropriate services to report to its 
authorities any incident referred to in Protocol I to the 
present Convention. That Party shall, if it considers it 
appropriate, report accordingly to the Organization and to 
any other party concerned.

16. "Clean ballast" means the ballast in a tank which since 
oil was last carried therein, has been so cleaned that 
effluent therefrom if it were discharged from a ship which is 
stationary into clean calm water on a clear day would not 
produce visible traces of oil on the surface of the water or 
upon adjoining shorelines or cause a sludge or emulsion to be 
deposited beneath the surface of the water or upon adjoining 
shorelines. If the ballast is discharged through an oil 
discharge monitoring and control system approved by the

other than oil or noxious substances as variously defined in 
the Annexes of the present Convention.

18. "Length" (L) means 96 per cent of the total length on a 
waterline at 85 per cent of the least moulded depth measured 
from the top of the keel, or the length from the foreside of 
the stem to the axis of the rudder stock on that waterline, 
if that be greater. In ships designed with a rake of keel the

assigned number freeboard and the lightweight of the ship.

23. "Lightweight" means the displacement of a ship in metric 
tons without cargo, oil fuel, lubricating oil, ballast water, 
fresh water and feedwater in tanks, consumable stores, 
passengers and their effects.

24. "Permeability" of a space means the ratio of the volume 
within that space which is assumed to be occupied by water to 
the total volume of that space.

requirements for oil discharge monitoring and control systems 
and slop tank arrangements shall apply three years after the 
date of entry into force 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

Oil Companies International Marine Forum.

The system shall be fitted with a recording device to provide 
a continuous record of the discharge in litres per nautical 
mile and total quantity discharged, or the oil content and 
rate of discharge. This record shall be identifiable as to 
time and date and shall be kept for at least three years. The 
oil discharge monitor and control system shall come into 
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.

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, 
within two years after the date of entry into force of the 
present Convention,
to comply with the provisions of this Regulation if such a 
tanker falls into either of the following categories:

a) a tanker, the delivery of which is after 1 January 1977; 
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

—where a centreline longitudinal bulkhead is provided:
     
(0.25 bi/B + 0.15)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.

ANNEX II

REGULATIONS FOR THE CONTROL OF POLLUTION BY NOXIOUS LIQUID IN 
BULK


Regulation 1

DEFINITIONS

For the purposes of this Annex:

1. "Chemical tanker" means a ship constructed or adapted 
primarily to carry a cargo of noxious liquid substances in 
bulk and includes an "oil tanker" as defined in Annex I of 
the present Convention when carrying a cargo or part cargo of 
noxious liquid substances in bulk.

2. "Clean ballast" means ballast carried in a tank which, 
since it was last used to carry a cargo containing a 
substance in Category A, B, C or D has been thoroughly 
cleaned and the residues resulting therefrom have been 
discharged and the tank emptied in accordance with the 
appropriate requirements of this Annex.

3. "Segregated ballast" means ballast water introduced into a 
tank permanently allocated to the carriage of ballast or to 
the carriage of ballast or cargoes other than oil or noxious 
liquid substances as variously defined in the Annexes of the 
present Convention, and which is completely separated from 
the cargo and oil fuel system.

4. "Nearest land" is as defined in Regulation 1(9) of Annex I 
of the present Convention.

5. "Liquid substances" are those having a vapour pressure not 
exceeding 2.8 kp/cm1 at a temperature of 37.8°C.

6. "Noxious liquid substance" means any substance designated 
in Appendix II to this Annex or provisionally assessed under 
the provisions of Regulation 3 (4) as falling into Category 
A, B, C or D.

7. "Special area" means a sea area where for recognized 
technical reasons in relation to its oceanographic and 
ecological condition and to its peculiar transportation 
traffic the adoption of special mandatory methods for the 
prevention of sea pollution by noxious liquid substances is 
required.

  Special areas shall be:

a) The Baltic Sea Area, and

b) The Black Sea Area.

8. "Baltic Sea Area" is as defined in Regulation 10(1)(b) of 
Annex I of the present Convention.

9. "Black Sea Area" is as defined in Regulation 10(1)(c) of 
Annex I of the present Convention.


Regulation 2

APPLICATION

1. Unless expressly provided otherwise the provisions of this 
Annex shall apply to all ships carrying noxious liquid 
substances in bulk.

2. Where a cargo subject to the provisions of Annex I of the 
present Convention is carried in a cargo space of a chemical 
tanker, the appropriate requirements of Annex I of the 
present Convention shall also apply.

3. Regulation 13 of this Annex shall apply only to ships 
carrying substances which are categorized for discharge 
control purposes in Category A, B or C.


Regulation 3

CATEGORIZATION AND LISTING OF NOXIOUS LIQUID SUBSTANCES

1. For the purpose of the Regulation of this Annex, except 
Regulation 13, noxious liquid substances shall be divided 
into four categories as follows:

a) Category A — Noxious liquid substances which if discharged 
into the sea from tank cleaning or deballasting operations 
would present a major hazard to either marine resources or 
human health or cause serious harm to amenities or other 
legitimate uses of the sea and therefore justify the 
application of stringent anti-pollution measures.

b) Category B — Noxious liquid substances which if discharged 
into the sea from tank cleaning or deballasting operations 
would present a hazard to either marine resources or human 
health or cause harm to amenities or other legitimate uses of 
the sea and therefore justify the application of special 
anti-pollution measures.

c) Category C — Noxious liquid substances which if discharged 
into the sea from tank cleaning or deballasting operations 
would present a minor hazard to either marine resources or 
human health or cause minor harm to amenities or other 
legitimate uses of the sea and therefore require special 
operational conditions.

d) Category D — Noxious liquid substances which if discharged 
into the sea from tank cleaning or deballasting operations 
would present a recognizable hazard to either marine 
resources or human health or cause minimal harm to amenities 
or other legitimate uses of the sea and therefore require 
some attention in operational conditions.

2. Guidelines for use in the categorization of noxious liquid 
substances are given in Appendix I to this Annex.

3. The list of noxious liquid substances carried in bulk and 
presently categorized which are subject to the provisions of 
this Annex is set out in Appendix II to this Annex.

4. Where it is proposed to carry a liquid substance in bulk 
which has not been categorized under paragraph (1) of this 
Regulation or evaluated as referred to in Regulation 4(1) of 
this Annex, the Governments of Parties to the Convention 
involved in the proposed operation shall establish and agree 
on a provisional assessment for the proposed operation on the 
basis of the guidelines referred to in paragraph (2) of this 
Regulation. Until full agreement between the Governments 
involved has been reached, the substance shall be carried 
under the most severe conditions proposed. As soon as 
possible, but not later than ninety days after its first 
carriage, the Administration concerned shall notify the 
Organization and provide details of the substance and the 
provisional assessment for prompt circulation to all Parties 
for their information and consideration. The Government of 
each Party shall have a period of ninety days in which to 
forward its comments to the Organization, with a view to the 
assessment of the substance.


Regulation 4

OTHER LIQUID SUBSTANCES

1. The substances listed in Appendix III to this Annex have 
been evaluated and found to fall outside the Categories A, B, 
C and D, as defined in Regulation 3(1) of this Annex because 
they are presently considered to present no harm to human 
health, marine resources, amenities or other legitimate uses 
of the sea, when discharged into the sea from tank cleaning 
or deballasting operations.

2. The discharge of bilge or ballast water or other residues 
or mixtures containing only substances listed in Appendix Ill 
to this Annex shall not be subject to any requirement of this 
Annex.

3. The discharge into the sea of clean ballast or segregated 
ballast shall not be subject to any requirement of this 
Annex.

3. Each Party shall notify the Organization, for transmission 
to the Parties concerned, of any case where facilities 
required under paragraph (1) of this Regulation are alleged 
to be inadequate.


Regulation 8

MEASURES OF CONTROL

1. The Government of each Party to the Convention shall 
appoint or authorize surveyors for the purpose of 
implementing this Regulation.

Category A Substances in all Areas

2. a) If a tank is partially unloaded or unloaded but not 
cleaned, an appropriate entry shall be made in the Cargo 
Record Book.

b) Until that tank is cleaned every subsequent pumping or 
transfer operation carried out in connexion with that tank 
shall also be entered in the Cargo Record Book.

3. If the tank is to be washed: 

a) the effluent from the tank washing operations shall be 
discharged from the ship to a reception facility at least 
until the concentration of the substance in the discharge, as 
indicated by analyses of samples of the effluent taken by the 
surveyor, has fallen to the residual concentration specified 
for that substance in Appendix II to this Annex. When the 
required residual concentration has been achieved, remaining 
tank washings shall continue to be discharged to the 
reception facility until the tank is empty. Appropriate 
entries of these operations shall be made in the Cargo Record 
Book and certified by the surveyor; and

b) after diluting the residue then remaining in the tank with 
at least 5 per cent of the tank capacity of water, this 
mixture may be discharged into the sea in accordance with the 
provisions of subparagraphs (l)(a) (b) and (c) or 7(a), (b) 
and (c), whichever is applicable, of regulation 5 of this 
Annex. Appropriate entries of these operations shall be made 
in the Cargo Record Book.

4. Where the Government of the receiving Party is satisfied 
that it is impracticable to measure the
concentration of the substance in the effluent without 
causing undue delay to the ship, that Party may accept an 
alternative procedure as being equivalent to sub-paragraph 
(3)(a) provided that:

a) a precleaning procedure for that tank and that substance, 
based on standards developed by the Organization, is approved 
by the Administration and that Party is satisfied that such 
procedure will fulfil the requirements of paragraph (1) or 
(7), whichever is applicable, of Regulation 5 of this
Annex with respect to the attainment of the prescribed 
residual concentrations;

b) a surveyor duly authorized by that Party shall certify in 
the Cargo Record Book that:

(i) the tank, its pump and piping system have been emptied, 
and that the quantity of cargo remaining in the tank is at or 
below the quantity on which the approved precleaning 
procedure referred to in sub-paragraph (ii) of this paragraph 
has been based;

(ii) precleaning has been carried out in accordance with the 
precleaning procedure approved by the Administration for that 
tank and that substance; and

(iii) the tank washings resulting from such precleaning have 
been discharged to a reception facility and the tank is 
empty;

c) the discharge into the sea of any remaining residues shall 
be in accordance with the provisions of paragraph (3)(b) of 
this Regulation and an appropriate entry is made in the Cargo 
Record Book.

Category B Substances outside Special Areas and Category C 
Substances in all Areas.

5. Subject to such surveillance and approval by the 
authorized or appointed surveyor as may be deemed necessary 
by the Government of the Party, the Master of a ship shall, 
with respect to a Category B substance outside a special area 
or a Category C substance in all areas, ensure compliance 
with the following:

a) If a tank is partially unloaded but not cleaned, an 
appropriate entry shall be made in the Cargo Record Book.

b) If the tank is to be cleaned at sea:

 (i) the cargo piping system serving that tank shall be 
drained and an appropriate entry made in the Cargo Record 
Book;
 (ii) the quantity of substance remaining in the
tank shall not exceed the maximum quantity which may be 
discharged into the sea for that substance under Regulation 
5(2)(c) of this Annex outside special areas in the case of 
Category B substances, or under Regulations 5(3)(c) and 
5(9)(c) outside and within special areas respectively in the 
case of Category C substances. An appropriate entry shall be 
made in the Cargo Record Book;

(iii) where it is intended to discharge the quantity of 
substance remaining into the sea the approved procedures 
shall be complied with, and the necessary dilution of the 
substance satisfactory for such a discharge shall be 
achieved. An appropriate entry shall be made in the Cargo 
Record Book; or

(iv) where the tank washings are not discharged into the sea, 
if any internal transfer of tank washings takes place from 
that tank an appropriate entry shall be made in the Cargo 
Record Book; and

(v) any subsequent discharge into the sea of such tank 
washings shall be made in accordance with the requirements of 
Regulation 5 of this Annex for the appropriate area and 
Category of substance involved.

c) If the tank is to be cleaned in port:

(i) the tank washings shall be discharged to a reception 
facility and an appropriate entry shall be made in the Cargo 
Record Book; or

(ii) the tank washings shall be retained on board the ship 
and appropriate entry shall be made in the Cargo Record Book 
indicating the location and disposition of the tank washings.

d) If after unloading a Category C substance within a special 
area, any residues or tank washings are to be retained on 
board until the ship is outside the special area, the Master

operation concerned and, when the ship is manned, each page 
shall be signed by the Master of the ship. The entries in the 
Cargo Record Book shall be in an official language of the 
State whose flag the ship is entitled to fly, and, for ships 
holding an International Pollution Prevention Certificate for 
the carriage of Noxious Liquid Substances in Bulk (1973) in 
English or French. The entries in an official national 
language of the State whose flag the ship is entitled to fly 
shall prevail in case of a dispute or discrepancy.

6. The Cargo Record Book shall be kept in such a place as to 
be readily available for inspection and, except in the case 
of unmanned ships under tow shall be kept on board the ship. 
It shall be retained for a period of two years after the last 
entry has been made.

7. The competent authority of the Government of a Party may 
inspect the Cargo Record Book on board any ship to which this 
Annex applies while the ship is in its port, and may make a 
copy of any entry in that book and may require the Master of 
the ship to certify that the copy is a true copy of such 
entry. Any copy so made which has been certified by the 
Master of the ship as a true copy of an entry in the ship's 
Cargo Record Book shall be made admissible in any judicial 
proceedings as evidence of the facts stated in the entry. The 
inspection of a Cargo Record Book and the taking of a 
certified copy by the competent authority under this 
paragraph shall be performed as expeditiously as possible 
without causing the ship to be unduly delayed.


Regulation 10 

SURVEYS

1. Ships which are subject to the provisions of this Annex 
and which carry noxious liquid substances in bulk shall be 
surveyed as follows:

a) An initial survey before a ship is put into service or 
before the certificate required by Regulation 11 of this 
Annex is issued for the first time, which shall include a 
complete inspection of its structure, equipment, fittings, 
arrangements and material in so far as the ship is covered by 
this Annex. The survey shall be such as to ensure full 
compliance with the applicable requirements of this Annex.

b) Periodical surveys at intervals specified by the 
Administration which shall not exceed five years and which 
shall be such as to ensure that the structure, equipment, 
fittings, arrangements and material fully comply with the 
applicable requirements of this Annex. However, where the 
duration of the International Pollution Prevention 
Certificate for the Carriage of Noxious Liquid Substances in 
Bulk (1973) is extended as specified in Regulation 12(2) or 
(4) of this Annex, the interval of the periodical survey may 
be extended correspondingly.

c) Intermediate surveys at intervals specified by the 
Administration which shall not exceed thirty months and which 
shall be such as to ensure that the equipment and associated 
pump and piping system, fully comply with the applicable 
requirements of this Annex and are in good working order. The 
survey shall be endorsed on the International Pollution 
Prevention Certificate for the Carriage of Noxious Liquid 
Substances in Bulk (1973) issued under Regulation 11 of this 
Annex.

2. Surveys of a ship with respect to the enforcement of the 
provisions of this Annex shall be carried out by officers of 
the Administration. The Administration may, however, entrust 
the surveys either to surveyors nominated for the purpose or 
to organizations recognized by it. In every case the 
Administration concerned shall fully guarantee the 
completeness and efficiency of the surveys.

3. After any survey of a ship under this Regulation has been 
completed, no significant change shall be made in the 
structure, equipment, fittings, arrangements or material, 
covered by the survey without the sanction of the 
Administration except the direct replacement of such 
equipment and fittings for the purpose of repair or 
maintenance.


Regulation 11

ISSUE OF CERTIFICATE

1. An International Pollution Prevention Certificate for the 
Carriage of Noxious Liquid Substances in Bulk (1973) shall be 
issued to any ship carrying noxious liquid substances which 
is engaged in voyages to ports or offshore terminals under 
the jurisdiction of other Parties to the Convention after 
survey of such ship in accordance with the provisions of 
Regulation 10 of this Annex. 

2. Such Certificate shall be issued either by the
Administration or by a person or organization duly authorized 
by it. In every case the Administration shall assume full 
responsibility for the Certificate.

3. a) The Government of a Party may, at the request of the 
Administration, cause a ship to be surveyed and if satisfied 
that the provisions of this Annex are complied with shall 
issue or authorize the issue of a Certificate to the ship in 
accordance with this Annex.

b) A copy of the Certificate and a copy of the survey report 
shall be transmitted as soon as possible to the requesting 
Administration.

c) A Certificate so issued shall contain a statement to the 
effect that it has been issued at the request of the 
Administration and shall have the same force and receive the 
same recognition as a certificate issued under paragraph (1) 
of this Regulation

d) No International Pollution Prevention Certificate for the 
Carriage of Noxious Liquid Substances in Bulk (1973) shall be 
issued to any ship which is entitled to fly the flag of a 
State which is not a Party.

4. The Certificate shall be drawn up in an official language 
of the issuing country in a form corresponding to the model 
given in Appendix V of this Annex. If the language used is 
neither English nor French, the text shall include a 
translation into one of these languages.


Regulation 12

DURATION OF CERTIFICATE

1. An International Pollution Prevention Certificate for the 
Carriage of Noxious Liquid Substances in Bulk (1973) shall be 
issued for a period specified by the Administration, which 
shall not exceed five years from the date of issue, except as 
provided in paragraphs (2) and (4) of this Regulation.

2. If a ship at the time when the Certificate expires is not 
in a port or offshore terminal under the jurisdiction of the 
Party to the Convention whose flag the ship is entitled to 
fly, the Certificate may be extended by the Administration, 
but such extension shall be granted only for the purpose of 
allowing the ship to complete its voyage to the State whose 
flag the ship is entitled to fly or in which it is to be 
surveyed and then only in cases where it appears proper and 
reasonable to do so.

3. No Certificate shall be thus extended for a period longer 
than five months and a ship to which such extension is 
granted shall not on its arrival in the State whose flag it 
is entitled to fly or the port in which it is to be surveyed, 
be entitled by virtue of such extension to leave that port or 
State without having obtained a new Certificate.

4. A Certificate which has not been extended under the 
provisions of paragraph (2) of this Regulation may be 
extended by the Administration for a period of grace of up to 
one month from the date of expiry stated on it.

5. A Certificate shall cease to be valid if significant 
alterations have taken place in the structure, equipment, 
fittings, arrangements and material required by this Annex 
without sanction of the Administration, except the direct 
replacement of such equipment or fitting for the purpose of 
repair or maintenance or if intermediate surveys as specified 
by the Administration under Regulation 10(1)(c) of this Annex 
are not carried out.

6. A Certificate issued to a ship shall cease to be valid 
upon transfer of such a ship to the flag of another State, 
except as provided in paragraph (7) of this Regulation.

7. Upon transfer of a ship to the flag of another Party, the 
Certificate shall remain in force for a period not exceeding 
five months provided that it would have expired before the 
end of that period, or until the Administration issues a 
replacement Certificate, whichever is earlier. As soon as 
possible after the transfer has taken place the Government of 
the Party whose flag the ship was formerly entitled to fly 
shall transmit to the Administration a copy of the 
Certificate carried by the ship before the transfer and, if 
available, a copy of the relevant survey report.

ANNEX III

REGULATIONS FOR THE PREVENTION OF POLLUTION BY HARMFUL 
SUBSTANCES CARRIED BY SEA IN PACKAGED FORMS OR IN FREIGHT 
CONTAINERS, PORTABLE TANKS OR ROAD AND RAIL TANK WAGONS


Regulation 1

APPLICATION

1. Unless expressly provided otherwise, the Regulations of 
this Annex apply to all ships carrying harmful substances in 
packaged forms, or in freight containers, portable tanks or 
road and rail tank wagons.

2. Such carriage of harmful substances is prohibited except 
in accordance with the provisions of this Annex.

3. To supplement the provisions of this Annex the Government 
of each Party to the Convention shall issue, or cause to be 
issued, detailed requirements on packaging, marking and 
labelling, documentation, stowage, quantity limitations, 
exceptions and notification, for preventing or minimizing 
pollution of the marine environment by harmful substances.

4. For the purpose of this Annex, empty receptacles, freight 
containers, portable tanks and road and rail tank wagons 
which have been used previously for the carriage of harmful 
substances shall themselves be treated as harmful substances 
unless adequate precautions have been taken to ensure that 
they contain no residue that is hazardous to the marine 
environment.


Regulation 2

PACKAGING

 Packagings, freight containers, portable tanks and road and 
rail tank wagons shall be adequate to minimize the hazard to 
the marine environment having regard to their specific 
contents.


Regulation 3

MARKING AND LABELLING

 Packages, whether shipped individually or in units or in 
freight containers, portable tanks or road and rail tank 
wagons containing a harmful substance, shall be durably 
marked with the correct technical name (trade names shall not 
be used as the correct technical name), and further marked 
with a distinctive label or stencil of label, indicating that 
the contents are harmful. Such identification shall be 
supplemented where possible by any other means, for example 
by the use of the United Nations number.


Regulation 4 

DOCUMENTATION

1. In all documents relating to the carriage of harmful 
substances by sea where such substances are named, the 
correct technical name of the substances shall be used (trade 
names shall not be used).

2. The shipping documents supplied by the shipper shall 
include a certificate or declaration that the shipment 
offered for carriage is properly packed, marked and labelled 
and in proper condition for carriage to minimize the hazard 
to the marine environment.

3. Each ship carrying harmful substances shall have a special 
list or manifest setting forth the harmful substances on 
board and the location thereof. A detailed stowage plan which 
sets out the location of all harmful substances on board may 
be used in place of such special list or manifest. Copies of 
such documents shall also be retained on shore by the owner 
of the ship or his representative until the harmful 
substances are unloaded.

4. In a case where the ship carries a special list or 
manifest or a detailed stowage plan, required for the 
carriage of dangerous goods by the International Convention 
for the Safety of Life at Sea in force, the documents 
required for the purpose of this Annex may be combined with 
those for dangerous goods. Where documents are combined, a 
clear distinction shall be made between dangerous goods and 
other harmful substances.


Regulation 5

STOWAGE

 Harmful substances shall be both properly stowed and secured 
so as to minimize the hazards to the marine environment 
without impairing the safety of ship and persons on board.


Regulation 6

QUANTITY LIMITATIONS

 Certain harmful substances which are very hazardous to the 
marine environment may, for sound scientific and technical 
reasons, need to be prohibited for carriage or be limited as 
to the quantity which may be carried aboard any one ship. In 
limiting the quantity due consideration shall be given to 
size, construction and equipment of the ship as well as the 
packaging and the inherent nature of the substance.


Regulation 7

EXCEPTIONS

1. Discharge by jettisoning of harmful substances carried in 
packaged forms, freight containers, portable tanks or road 
and rail tank wagons shall be prohibtied except where 
necessary for the purpose of securing the safety of the ship 
or saving life at sea.

2. Subject to the provisions of the present Convention, 
appropriate measures based on the physical, chemical and 
biological properties of harmful substances shall be taken to 
regulate the washing of leakages overboard provided that 
compliance with such measures would not impair the safety of 
the ship and persons on board.


Regulation 8

NOTIFICATION

 With respect of certain harmful substances, as may be 
designated by the Government of a Party to the Convention, 
the master or owner of the ship or his representative shall 
notify the appropriate port authority of the intent to load 
or unload such substances at least 24 hours prior to such 
action.

guarantee the completeness and efficiency of the survey and 
inspection and shall undertake to ensure the necessary 
arrangements to satisfy this obligation.

4. a) The condition of the ship and its equipment shall be 
maintained with the provisions of the present Protocol to 
ensure that the ship in all respects will remain fit to 
proceed to sea without presenting an unreasonable threat of 
harm to the marine environment.
