INTERNATIONAL CONVENTION ON TONNAGE MEASUREMENT OF SHIPS, 1969
INTERNATIONAL CONVENTION ON TONNAGE MEASUREMENT OF SHIPS, 1969
Whole document
The Contracting Governments,
DESIRING to establish uniform principles and rules with respect to the
determination of tonnage of ships engaged on international voyages;
CONSIDERING that this end may best be achieved by the conclusion of a
Convention;
HAVE AGREED as follows:
Article 1 General Obligation under the Convention
The Contracting Governments undertake to give effect to the provisions
of the present Convention and the Annexes hereto which shall constitute an
integral part of the present Convention. Every reference to the present
Convention constitutes at the same time a reference to the Annexes.
Article 2 Definitions
For the purpose of the present Convention, unless expressly provided
otherwise:
(1) "Regulations" means the Regulations annexed to the present
Convention;
(2) "Administration" means the Government of the State whose flag the
ship is flying;
(3) "international voyage" means a sea voyage from a country to which
the present Convention applies to a port outside such country, or
conversely. For this purpose, every territory for the international
relations of which a Contracting Government is responsible or for which
the United Nations are the administering authority is regarded as a
separate country;
(4) "gross tonnage" means the measure of the overall size of a ship
determined in accordance with the provisions of the present Convention;
(5) "net tonnage" means the measure of the useful capacity of a ship
determined in accordance with the provisions of the present Convention;
(6) "new ship" means a ship the keel of which is laid, or which is at
a similar stage of construction, on or after the date of coming into force
of the present Convention;
(7) "existing ship" means a ship which is not a new ship;
(8) "length" 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 fore side 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 waterline on which this length is measured shall be parallel
to the designed waterline;
(9) "Organization" means the Inter-Governmental Maritime Consultative
Organization.
Article 3 Application
(1) The present Convention shall apply to the following ships engaged
on international voyages;
(a) ships registered in countries the Governments of which are
Contracting Governments;
(b) ships registered in territories to which the present Convention is
extended under Article 20; and
(c) unregistered ships flying the flag of a State, the Government of
which is a Contracting Government.
(2) The present Convention shall apply to:
(a) new ships;
(b) existing ships which undergo alterations or modifications which
the Administration deems to be a substantial variation in their existing
gross tonnage;
(c) existing ships if the owner so requests; and
(d) all existing ships, twelve years after the date on which the
Convention comes into force, except that such ships, apart from those
mentioned in (b) and (c) of this paragraph, shall retain their then
existing tonnages for the purpose of the application to them of relevant
requirements under other existing International Conventions.
(3) Existing ships to which the present Convention has been applied in
accordance with sub-paragraph (2) (c) of this Article shall not
subsequently have their tonnages determined in accordance with the
requirements which the Administration applied to ships on international
voyages prior to the coming into force of the present Convention.
Article 4 Exceptions
(1) The present Convention shall not apply to:
(a) ships of war; and
(b) ships of less than 24 metres (79 feet) in length.
(2) Nothing herein shall apply to ships solely navigating:
(a) the Great Lakes of North America and the River St. Lawrence as far
east as a rhumb line drawn from Cap des Rosiers to West Point, Anticosti
Island, and, on the north side of Anticosti Island, the meridian of
longitude 63¡ãW;
(b) the Caspian Sea; or
(c) the Plate, Parana and Uruguay Rivers as far east as a rhumb line
drawn between Punta Rasa (Cabo San Antonio), Argentina, and Punta del
Este, Uruguay.
Article 5 Force Majeure
(1) A ship which is not subject to the provisions of the present
Convention at the time of its departure on any voyage shall not become
subject to such provisions on account of any deviation from its intended
voyage due to stress of weather or any other cause of force majeure.
(2) In applying the provisions of the present Convention, the
Contracting Governments shall give due consideration to any deviation or
delay caused to any ship owing to stress of weather or any other cause of
force majeure.
Article 6 Determination of Tonnages
The determination of gross and net tonnages shall be carried out by
the Administration which may, however, entrust such determination either
to persons or organizations recognized by it. In every case the
Administration Concerned shall accept full responsibility for the
determination of gross and net tonnages.
Article 7 Issue of Certificate
(1) An International Tonnage Certificate (1969) shall be issued to
every ship, the gross and net tonnages of which have been determined in
accordance with the present Convention.
(2) Such certificate shall be issued by the Administration or by any
person or organization duly authorized by it. In every case, the
Administration shall assume full responsibility for the certificate.
Article 8 Issue of Certificate by another Government
(1) A Contracting Government may, at the request of another
Contracting Government, determine the gross and net tonnages of a ship
and issue or authorize the issue of an International Tonnage Certificate
(1969) to the ship in accordance with the present Convention.
(2) A copy of the certificate and a copy of the calculations of the
tonnages shall be transmitted as early as possible to the requesting
Government.
(3) A certificate so issued shall contain a statement to the effect
that it has been issued at the request of the Government of the State
whose flag the ship is or will be flying and it shall have the same
validity and receive the same recognition as a certificate issued under
Article 7.
(4) No International Tonnage Certificate (1969) shall be issued to a
ship which is flying the flag of a State the Government of which is not a
Contracting Government.
Article 9 Form of Certificate
(1) The certificate shall be drawn up in the official language or
languages of the issuing country. If the language used is neither English
nor French, the text shall include a translation into one of these
languages.
(2) The form of the certificate shall correspond to that of the model
given in Annex II.
Article 10 Cancellation of Certificate
(1) Subject to any exceptions provided in the Regulations, an
International Tonnage Certificate (1969) shall cease to be valid and shall
be cancelled by the Administration if alterations have taken place in the
arrangement, construction, capacity, use of spaces, total number of
passengers the ship is permitted to carry as indicated in the ship's
passenger certificate, assigned load line or permitted draught of the
ship, such as would necessitate an increase in gross tonnage or net
tonnage.
(2) A certificate issued to a ship by an Administration shall cease to
be valid upon transfer of such a ship to the flag of another State, except
as provided in paragraph (3) of this Article.
(3) Upon transfer of a ship to the flag of another State the
Government of which is a Contracting Government, the International Tonnage
Certificate (1969) shall remain in force for a period not exceeding three
months, or until the Administration issues another International Tonnage
Certificate (1969) to replace it, whichever is the earlier. The
Contracting Government of the State whose flag the ship was flying
hitherto shall transmit to the Administration as soon as possible after
the transfer takes place a copy of the certificate carried by the ship at
the time of transfer and a copy of the relevant tonnage calculations.
Article 11 Acceptance of Certificate
The certificate issued under the authority of a Contracting Government
in accordance with the present Convention shall be accepted by the other
Contracting Governments and regarded for all purposes covered by the
present Convention as having the same validity as certificates issued by
them.
Article 12 Inspection
(1) A ship flying the flag of a State the Government of which is a
Contracting Government shall be subject, when in the ports of other
Contracting Governments, to inspection by officers duly authorized by such
Governments. Such inspection shall be limited to the purpose of verifying:
(a) that the ship is provided with a valid International Tonnage
Certificate (1969); and
(b) that the main characteristics of the ship correspond to the data
given in the certificate.
(2) In no case shall the exercise of such inspection cause any delay
to the ship.
(3) Should the inspection reveal that the main characteristics of the
ship differ from those entered on the International Tonnage Certificate
(1969) so as to lead to an increase in the gross tonnage or the net
tonnage, the Government of the State whose flag the ship is flying shall
be informed without delay.
Article 13 Privileges
The privileges of the present Convention may not be claimed in favour
of any ship unless it holds a valid certificate under the Convention.
Article 14 Prior Treaties, Conventions and Arrangements
(1) All other treaties, conventions and arrangements relating to
tonnage matters at present in force between Governments Parties to the
present Convention shall continue to have full and complete effect during
the terms thereof as regards:
(a) ships to which the present Convention does not apply; and
(b) ships to which the present Convention applies, in respect of
matters for which it has not expressly provided.
(2) To the extent, however, that such treaties, conventions, or
arrangements conflict with the provisions of the present Convention, the
provisions of the present Convention shall prevail.

ANNEX I REGULATIONS FOR DETERMINING GROSS AND NET TONNAGES OFSHIPS
Regulation 1 General
(1) The tonnage of a ship shall consist of gross tonnage and net
tonnage.
(2) The gross tonnage and the net tonnage shall be determined in
accordance with the provisions of these Regulations.
(3) The gross tonnage and the net tonnage of novel types of craft
whose constructional features are such as to render the application of the
provisions of these Regulations unreasonable or impracticable shall be as
determined by the Administration. Where the tonnage is so determined, the
Administration shall communicate to the Organization details of the method
used for that purpose, for circulation to the Contracting Governments for
their information.
Regulation 2 Definitions of Terms used in the Annexes
(1) Upper Deck
The upper deck is the uppermost complete deck exposed to weather and
sea, which has permanent means of weathertight closing of all openings in
the weather part thereof, and below which all openings in the sides of the
ship are fitted with permanent means of watertight closing in a ship
having a stepped upper deck, the lowest line of the exposed deck and the
continuation of that line parallel to the upper part of the deck is taken
as the upper deck.
(2) Moulded Depth
(a) The moulded depth is the vertical distance measured from the top
of the keel to the underside of the upper deck at side. In wood and
composite ships the distance is measured from the lower edge of the keel
rabbet. Where the form at the lower part of the midship section is of a
hollow character, or where thick garboards are fitted, the distance is
measured from the point where the line of the flat of the bottom continued
inwards cuts the side of the keel.
(b) In ships having rounded gunwales, the moulded depth shall be
measured to the point of intersection of the moulded lines of the deck and
side shell plating, the lines extending as though the gunwales were of
angular design.
(c) Where the upper deck is stepped and the raised part of the deck
extends over the point at which the moulded depth is to be determined, the
moulded depth shall be measured to a line of reference extending from the
lower part of the deck along a line parallel with the raised part.
(3) Breadth
The breadth is the maximum breadth of the ship, measured amidships to
the moulded line of the frame in a ship with a metal shell and to the
outer surface of the hull in a ship with a shell of any other material.
(4) Enclosed Spaces
Enclosed spaces are all those spaces which are bounded by the ship's
hull, by fixed or portable partitions or bulkheads, by decks or coverings
other than permanent or movable awnings. No break in a deck, nor any
opening in the ship's hull, in a deck or in a covering of a space, or in
the partitions or bulkheads of a space, nor the absence of a partition or
bulkhead, shall preclude a space from being included in the enclosed
space.
(5) Excluded Spaces
Notwithstanding the provisions of paragraph (4) of this Regulation,
the spaces referred to in subparagraphs (a) to (e) inclusive of this
paragraph shall be called excluded spaces and shall not be included in the
volume of enclosed spaces, except that any such space which fulfils at
least one of the following three conditions shall be treated as an
enclosed space:
- the space is fitted with shelves or other means for securing cargo
or stores;
- the openings are fitted with any means of closure;
- the construction provides any possibility of such openings being
closed.
(a) (i) A space within an erection opposite an end opening extending
from deck to deck except for a curtain plate of a depth not exceeding by
more than 25 millimetres (one inch) the depth of the adjoining deck beams,
such opening having a breadth equal to or greater than 90 per cent of the
breadth of the deck at the line of the opening of the space. This
provision shall be applied so as to exclude from the enclosed spaces only
the space between the actual end opening and a line drawn parallel to the
line or face of the opening at a distance from the opening equal to one
half of the width of the deck at the line of the opening (Figure 1 in
Appendix 1).
(a) (ii) Should the width of the space because of any arrangement
except by convergence of the outside plating, become less than 90 per cent
of the breadth of the deck, only the space between the line of the
opening and a parallel line drawn through the point where the athwartships
width of the space becomes equal to, or less than, 90 per cent of the
breadth of the deck shall be excluded from the volume of enclosed spaces
(Figures 2, 3 and 4 in Appendix 1).
(a) (iii) Where an interval which is completely open except for
bulwarks or open rails separates any two spaces, the exclusion of one or
both of which is permitted under sub-paragraphs (a) (i) and/or (a) (ii),
such exclusion shall not apply if the separation between the two spaces is
less than the least half breadth of the deck in way of the separation
(Figures 5 and 6 in Appendix 1).
(b) A space under an overhead deck covering open to the sea and
weather, having no other connexion on the exposed sides with the body of
the ship than the stanchions necessary for its support. In such a space,
open rails or a bulwark and curtain plate may be fitted or stanchions
fitted at the ship's side, provided that the distance between the top of
the rails or the bulwark and the curtain plate is not less than 0.75
metres (2.5 feet) or one-third of the height of the space, whichever is
the greater (Figure 7 in Appendix 1).
(c) A space in a side-to-side erection directly in way of opposite
side openings not less in height than 0.75 metres (2.5 feet) or one-third
of the height of the erection, whichever is the greater. If the opening
in such an erection is provided on one side only, the space to be
excluded from the volume of enclosed spaces shall be limited inboard from
the opening to a maximum of one-half of the breadth of the deck in way of
the opening (Figure 8 in Appendix 1).
(d) A space in an erection immediately below an uncovered opening in
the deck overhead, provided that such an opening is exposed to the
weather and the space excluded from enclosed spaces is limited to the area
of the opening (Figure 9 in Appendix 1).
(e) A recess in the boundary bulkhead of an erection which is exposed
to the weather and the opening of which extends from deck to deck without
means of closing, provided that the interior width is not greater than the
width at the entrance and its extension into the erection is not greater
than twice the width of its entrance (Figure 10 in Appendix 1).
(6) Passenger
A passenger is every person other than:
(a) the master and the members of the crew or other persons employed
or engaged in any capacity on board a ship on the business of that ship;
and
(b) a child under one year of age.
(7) Cargo Spaces
Cargo spaces to be included in the computation of net tonnage are
enclosed spaces appropriated for the transport of cargo which is to be
discharged from the ship, provided that such spaces have been included in
the computation of gross tonnage. Such cargo spaces shall be certified by
permanent marking with the letters CC (cargo compartment) to be so
positioned that they are readily visible and not to be less than 100
millimetres (4 inches) in height.
(8) Weathertight
Weathertight means that in any sea conditions water will not penetrate
into the ship.
Regulation 3 Gross Tonnage
The gross tonnage (GT) of a ship shall be determined by the following
formula:
|------|
| GT = K V |
| 1 |
|------|
where: V = total volume of all enclosed spaces of the ship in cubic
metres.
|-------|
| K = 0.2 + 0.02 log V | (or as tabulated in Appendix 2).
| 1 10 |
|-------|
Regulation 4 Net Tonnage
(1) The net tonnage (NT) of a ship shall be determined by the
following formula:
|-------------|
| 2 |
| N |
| 4d 2 |
| NT = K V (---) + K (N + --) |
| 2 c 3D 3 1 10 |
|-------------|
in which formula:
|--|
| 2 |
| 4d |
(a) the factor | (--) |shall not be taken as greater than unity;
| 3D |
|--|
|----|
| 2|
| 4d |
(b) the term | K V (--)| shall not be taken as less than 0.25GT; and
| 2 c 3D |
|----|
(c) NT shall not be taken as less than 0.30GT, and in which:
|--|
| V | = total volume of cargo spaces in cubic metres,
| c|

|-------|
| K = 0.2 + 0.02 log V | (or as tabulated in Appendix 2),
| 2 10 c |
|-------|
|-------|
| GT + 10000|
| K = 1.25 ---| ,
| 3 10000 |
|-------|
D = moulded depth amidships in metres as defined in Regulation 2 (2),
d = moulded draught amidships in metres as defined in paragraph (2) of
this Regulation,
|---|
| N | = number of passengers in cabins with not more than 8 berths,
| 1 |
|---|
|---|
| N | = number of other passengers,
| 2 |
|---|
N + N = total number of passengers the ship is permitted to carry
1 2
as indicated in the
ship's passenger certificate; when N + N is less than 13, N and N
shall
1 2 1 2 be
taken as zero,
GT = gross tonnage of the ship as determined in accordance with the
provisions of Regulation 3.
(2) The moulded draught (d) referred to in paragraph (1) of this
Regulation shall be one of the following draughts:
(a) for ships to which the International Convention on Load Lines in
force applies, the draught corresponding to the Summer Load Line (other
than timber load lines) assigned in accordance with that Convention;
(b) for passenger ships, the draught corresponding to the deepest
subdivision load line assigned in accordance with the International
Convention for the Safety of Life at Sea in force or other international
agreement where applicable;
(c) for ships to which the International Convention on Load Lines does
not apply but which have been assigned a load line in compliance with
national requirements, the draught corresponding to the summer load line
so assigned;
(d) for ships to which no load line has been assigned but the draught
of which is restricted in compliance with national requirements, the
maximum permitted draught;
(e) for other ships, 75 per cent of the moulded depth amidships as
defined in Regulation 2 (2).
Regulation 5 Change of Net Tonnage
(1) When the characteristics of a ship, such as V, V , d, N or N
c 1 2
as defined in Regulations 3 and 4, are altered and where such an
alteration results in an increase in its net tonnage as determined in
accordance with the provisions of Regulation 4, the net tonnage of the
ship corresponding to the new characteristics shall be determined and
shall be applied without delay.
(2) A ship to which load lines referred to in subparagraphs (2) (a)
and (2) (b) of Regulation 4 are concurrently assigned shall be given only
one net tonnage as determined in accordance with the provisions of
Regulation 4 and that tonnage shall be the tonnage applicable to the
appropriate assigned load line for the trade in which the ship is engaged.
(3) When the characteristics of a ship such as V, V , d, N or N
c 1 2
as defined in Regulations 3 and 4 are altered or when the appropriate
assigned load line referred to in paragraph (2) of this Regulation is
altered due to the change of the trade in which the ship is engaged, and
where such an alteration results in a decrease in its net tonnage as
determined in accordance with the provisions of Regulation 4, a new
International Tonnage Certificate (1969) incorporating the net tonnage so
determined shall not be issued until twelve months have elapsed from the
date on which the current Certificate was issued, provided that this
requirement shall not apply:
(a) if the ship is transferred to the flag of another State, or
(b) if the ship undergoes alterations or modifications which are
deemed by the Administration to be of a major character, such as the
removal of a superstructure which requires an alteration of the assigned
load line, or
(c) to passenger ships which are employed in the carriage of large
numbers of unberthed passengers in special trades, such, for example, as
the pilgrim trade.
Regulation 6 Calculation of Volumes
(1) All volumes included in the calculation of gross and net tonnages
shall be measured, irrespective of the fitting of insulation or the like
to the inner side of the shell or structural boundary plating in ships
constructed of metal, and to the outer surface of the shell or to the
inner side of structural boundary surfaces in ships constructed of any
