附则： 测定船舶总吨位和净吨位规则
第一条 总 则
１． 船舶的吨位应包括总吨位和净吨位。
２． 总吨位和净吨位应根据本规则各项规定予以测定。
３． 新奇型式船艇的总吨位和净吨位，由于其构造的特点，以致不能合理应用或难以实用本规则各条规定时，应由主管机关决定其总吨位和净吨位。如果吨位是这样决定的，主管机关应将为此所采用的方法细节通知海协组织，以便分送各缔约政府，供其参考。
第二条 本附则中所用名词的定义
１． 上甲板
上甲板是指最高一层露天全通甲板，在露天部分上的一切开口，设有永久性水密关闭装置，而且在该甲板下面船旁两侧的一切开口，也有永久性的水密关闭装置。如船舶具有阶形上甲板，则取最低的露天甲板线和其平行于甲板较高部分的延伸线作为上甲板。
２． 型深
（１）型深是指从龙骨上面量到船舷处上甲板下面的垂直距离。对木质船舶和铁木混合结构船舶，垂直距离是从龙骨镶口的下缘量起。倘船舶中央横剖面的底部具有凹形，或装有加厚的龙骨翼板时，垂直距离是从船底平坦部分向内引伸与龙骨侧面相交的一点量起。
（２）具有圆弧形舷边的船舶，型深是量到甲板型线和船舷外板型线相交之点，这些线的引伸是把该舷边看作是设计为角形的。
（３）当上甲板为阶形甲板，并且其升高部分延伸超过决定型深的一点时，型深应量到此甲板较低部分的引伸虚线，此虚线平行于甲板升高部分。
３． 宽度
宽度是指船舶的最大宽度，对金属壳板的船，其宽度是在船长中点处量到两舷的肋骨型线，对其它材料壳板的船，其宽度在船长中点量到船体外面。
４． 围蔽处所
围蔽处所是指由船壳、固定的或可移动的隔板或舱壁、甲板或盖板所围成的所有处所，但永久的或可移动的天蓬除外，无论是甲板上有间断处，或船壳上有开口，或甲板上有开口，或某一处所的盖板上有开口，或某一处所的隔板或舱壁上有开口，以及一面未设隔板或舱壁的处所，都不妨碍将这些处所计入围蔽处所之内。
５． 免除处所
虽然本条第４款有所规定，本款下列各项（１）至（５）所述处所仍应称为免除处所，不计入围蔽处所容积之内。但符合以下三条件之一者，应作为围蔽处所：
——设有框架或其它设施保护货物和物料的处所；
——开口上设有某种封闭设备；
——具有能使其开口封闭的建筑物。
（１）１）甲板上建筑物内某一处所，它面对着高度为全甲板间的端部开口，且开口上沿板的高度不超过其邻近甲板横梁的高度２５毫米（１英寸），如开口的宽度等于或大于该开口处甲板宽度的９０％，则从实际端部开口起，至等于开口处甲板宽度的一半距离绘一与开口线或面相平行的线，这个处所可不计入围蔽处所之内（见附录Ｉ中图１）。
２）如该处所的宽度由于任何布置上的原因，包括由于船壳板的收敛，使其宽度小于开口处甲板宽度的９０％，则从开口线起，至船体横向宽度等于或小于开口处甲板宽度的９０％处绘一与开口平行的线，这个处所可不计入围蔽处所之内（见附录Ｉ中图２、３、４）。
３）如果两个处所由一间隔区分开，而且间隔区除了舷墙和栏杆外是完全开敞的，则可按（１）１）或２）的规定将其中一个或两个处所免除量计；但如果两个处所之间的间隔距离小于间隔区甲板最小宽度的一半，就不适用这种免除（见附录Ｉ中图５和６）。
（２）在架空露天甲板下的处所，其开敞的两侧与船体除了必要的支柱外并无其它连接。在这种处所，可以设置栏杆、舷墙及舷边上沿板，或在船边安设支柱，但栏杆顶或舷墙顶与舷边上沿板之间的距离，应不小于０．７５米（２．５英尺），或不小于该处所高度的１／３，以较大者为准（见附录Ｉ中图７）。
（３）伸展到两舷的建筑物内的处所，其两侧的相对开口的高度不小于０．７５米（２．５英寸），或不小于建筑物高度的１／３，以较大者为准。如果这种建筑物只在一侧有开口，则从围蔽处所中免除计量的处所仅限于从开口向内最多伸到该开口处甲板宽度的一半（见附录Ｉ中图８）。
（４）建筑物内，直接位于其顶甲板上无覆盖的开口之下的某一处所，倘这种开口是露天的，则从围蔽处所中免除计量的处所仅限于此开口区域（见附录Ｉ中图９）。
（５）由建筑物的界限舱壁形成的某一壁龛，这种壁龛是露天的，其开口高度为甲板间的全高度，无封闭设备，而且壁龛内宽度不大于其入口处宽度，同时从入口伸至内壁的深度不大于入口处宽度的２倍（见附录Ｉ中图１０）。
６． 旅客
除下列人员外，均为旅客：
（１）船长和船员，以及在船上雇用或从事该船任何业务的其它人员；
（２）一周岁以下的儿童。
７． 载货处所
净吨位计算中所包括的载货处所，是指适宜于运载由船上起卸货物的围蔽处所，而且这些处所已经列入总吨位计算之内。上述载货处所应在易于看到的地方用字母ＣＣ（货舱）作永久性标志，字母的高度应不小于１００毫米（４英寸），以便查核。
８． 水密
水密是指在任何海况下，水都不会浸入船内。
第三条 总 吨 位
船舶总吨位（ＧＴ）应按下述公式决定：
ＧＴ＝Ｋ１Ｖ其中：Ｖ＝船舶所有围蔽处所的总容积，立方米；
Ｋ１＝０．２＋０．０２ｌｏｇ１０ｖ（或取附录Ⅱ表中所示）。
第四条 净 吨 位
１． 船舶净吨位（ＮＴ）应按下述公式决定：
４ｄ Ｎ２
ＮＴ＝Ｋ２Ｖ０（－－）２＋Ｋ３（Ｎ１＋－－）
３Ｄ １０
式中：
４ｄ
（１）因素（－－）２应不大于１；
３Ｄ
４ｄ
（２）Ｋ２Ｖ０（－－）２应不小于０．２５ＧＴ；
３Ｄ
（３）ＮＴ应不小于０．３０ＧＴ；
其中：
Ｖ０＝各载货处所的总容积，立方米：
Ｋ２＝０．２＋０．０２ｌｏｇ１０ｖ０（或取附录Ⅱ表中所示）；
ＧＴ＋１０．０００
Ｋ３＝１．２５－－－－－－－－－；
１０．０００


Ｄ＝本规则第二条２．款中所述船长中点的型深，米；
ｄ＝本条第２．款所述船长中点的型吃水，米；
Ｎ１＝不超过８个铺位的客舱中的旅客数；
Ｎ２＝其它旅客数；
Ｎ１＋Ｎ２＝船舶乘客证书中所载准许乘客总数；
当Ｎ１＋Ｎ２小于１３时，Ｎ１及Ｎ２均取为零。
ＧＴ＝根据本规则第三条决定的船舶总吨位。
２． 关于本条第１．款中所指的型吃水，应为下述吃水之一：
（１）对于适用现行国际船舶载重线公约的船舶，其吃水相当于按该公约所勘定的夏季载重线（木材载重线除外）；
（２）对于客船，其吃水相当于按现行国际海上人命安全公约或其它适用的国际协定所勘定的最深分舱载重线；
（３）对于不适用现行国际船舶载重线公约而按国家要求勘定其载重线的船舶，其吃水相当于按该国家要求所勘定的夏季载重线；
（４）对于未勘定载重线，但其吃水是按国家要求予以限制的船舶，最大许可吃水即为其型吃水；
（５）对于其它船舶，则以本规则第二条２．款所述船长中点型深的７５％作为型吃水。
第五条 净吨位的变更
１． 当一船的特性，如本规则第三和第四条所述的Ｖ，Ｖｃ，ｄ，Ｎ１或Ｎ２有改变，同时这种改变引起船舶按第四条所决定的净吨位增加时，则此船的净吨位应迅即按其相应的新特性予以测定。
２． 对于同时按第四条２．（１）和２．（２）勘定载重线的船舶，仅需按第四条规定给予一种净吨位，此净吨位应适应于该船从事的业务所勘定的载重线。
３． 当一船的特性，如本规则第三和第四条所述的Ｖ，Ｖｃ，ｄ，Ｎ１或Ｎ２有改变，或是因该船从事的业务改变而涉及到本条２．款所规定的相应载重线改变，并且这种改变引起船舶按第四条所决定的净吨位减少时，则适合此项净吨位的新国际吨位证书（１９６９），应在现行吨位证书签发之日起十二个月以后发给；但这项要求不适用于下述情况；
（１）如果船舶转移为悬挂另一国家的国旗；
（２）如果船舶经改装或改建，主管机关认为这种改装或改建的性质重大，例如因上层建筑拆除而需要改变原勘定的载重线。
（３）从事特种业务而载运大量无铺位旅客的客船，例如朝圣业务。
第六条 容积的计算
１． 列入总吨位和净吨位计算中的所有容积，不管是否装有绝缘物或类似绝缘物，对金属结构的船舶应量到船壳板内侧或结构的边界板内侧；对其它材料结构的船舶，应量到船壳的外表面或结构的边界内表面。
２． 船体凸出部分的容积，应列入总容积之内。
３． 露天处所的容积，可从总容积中除去。
第七条 量度和计算
１． 容积计算中所采用的量度应取至厘米、或二十分之一英尺的最近值。
２． 对有关处所的容积应按一般公认的方法计算，并应达到主管机关认可的精确度。
３． 计算应充分详细，以便于核对。
（译注：本规则第二条５．（５）中说明“……从入口伸至内壁的深度不大于入口处宽度的２倍……”，但附录Ｉ图１０中右边所绘作为围蔽处所的Ｉ，注为ｌ１＜２ｗ１，这个注似有错误，应为ｌ１＞２ｗ１）。

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°W;
(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.

Article 15 Communication of Information
The Contracting Governments undertake to communicate to and deposit
with the Organization:
(a) a sufficient number of specimens of their certificates issued
under the provisions of the present Convention for circulation to the
Contracting Governments;
(b) the text of the laws, orders, decrees, regulations and other

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 thecontinuation 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 |
|--------------------------|
|-----------------
