PART I — GENERAL

Citation, commencement and revocation

1

Definitions

2

PART II — APPLICATION, ASCERTAINMENT OF TONNAGE AND CERTIFICATION FOR UNITED KINGDOM SHIPS OF 24 METRES IN LENGTH AND OVER

Application

3

This Part applies to ships, being ships of 24 metres in length or over, registered or to be registered in the United Kingdom under Part II of the Act and for which the ascertainment of tonnage is required under Regulations made under section 10 of the Act.

Method of measurement

4

Calculation of volumes

5

Gross tonnage

6

The gross tonnage (GT) of a ship shall be determined by the following formula—

$$GT=K1V$ where— V total volume of all enclosed spaces of the ship in cubic metres; and K₁ 0.2 + 0.02 log₁₀ V, as specified in Schedule 2;$

Net tonnage

7

The net tonnage (NT) of a ship shall be determined by the following formula—

$$NT=K2Vc(4d3D)2+K3(N1+N210)$ where— Vc total volume of cargo spaces in cubic metres; K₂ 0.2 + 0.02 log₁₀ Vc , as specified in Schedule 2. K₃ $1.25GT+10,00010,000$ GT gross tonnage calculated in accordance with regulation 6; D moulded depth amidships in metres; d moulded draught amidships in metres; N₁ number of berths for passengers in cabins with not more than 8 berths; and N₂ number of other passengers who may be accommodated on the ship; provided that— the factor— $(4d3D)2$ shall not be taken as greater than unity; the term— $K2Vc(4d3D)2$ shall not be taken as less than 0.25 GT; N₁ and N₂ shall be taken as zero when N₁ + N₂ is less than 13; and NT shall not be taken as less than 0.30 GT.$

Segregated ballast oil tankers

8

Where segregated ballast tanks complying with Regulation 13 of Annex 1 of the International Convention for the Prevention of Pollution from Ships 1973[^f00008], as modified by the Protocol of 1978[^f00009] relating to that Convention, are provided in oil tankers, an entry may be made on the International Tonnage Certificate (1969) indicating the total tonnage of these tanks. The tonnage of such segregated ballast shall be calculated according to the following formula—

$$K1×Vb$ where— K₁ 0.2 + 0.02 log₁₀ V, as specified in Schedule 2; V the total volume of all enclosed spaces of the ship in cubic metres; and Vb the total volume of segregated ballast tanks in cubic metres measured in accordance with regulation 5.$

Issue of certificates

9

If it is in order to do so, the Certifying Authority shall issue to the owner an International Tonnage Certificate (1969) in the form set out in the Convention certifying the tonnages of the ship and containing the particulars to be shown thereon. The official number of the ship shall be included as a distinctive number.

Cancellation of certificates

10

Change of net tonnage necessitating issue of certificate

11

Use of gross tonnage ascertained under previous Regulations

12

the Secretary of State may permit the continuing use of a gross tonnage additionally ascertained in accordance with the provisions of Schedule 5 and Appendices 1 to 4 thereto of the Merchant Shipping (Tonnage) Regulations 1982 for the purpose of the application of the provisions of regulations implementing the International Convention for the Safety of Life at Sea 1974[^f00010], the Protocol of 1978 relating to that Convention[^f00011], the International Convention for the Prevention of Pollution from Ships, 1973, the Protocol of 1978 relating to that Convention and the International Convention on Standards of Training, Certification and Watchkeeping of Seafarers, 1978[^f00012], as amended on 7th July 1995.

Explanatory note

(This note is not part of the Regulations)

These Regulations consolidate with amendments the Merchant Shipping (Tonnage) Regulations 1982, as amended.

The Regulations re-enact those provisions of the earlier Regulations relating to the International Convention on Tonnage Measurement of Ships 1969 (Cmnd. 4332) (Part II), and the calculation of tonnage for pleasure vessels of less than 13.7 metres in length (Part III).

The Regulations simplify the earlier tonnage requirements for ships of less than 24 metres in length by adopting a method of tonnage computation, previously restricted to those pleasure vessels of less than 13.7 metres in length, for all ships under 24 metres in length other than fishing vessels.

The Regulations deal with the tonnage computation of segregated ballast oil tankers, and with the use of gross tonnage which has been ascertained under previous Regulations.

The Regulations enable the Secretary of State to authorise persons to act as Certifying Authorities for the purpose of the Regulations. Currently so authorised are Lloyd’s Register of Shipping, the British Committee of Bureau Veritas, the British Committee of Det Norske Veritas, the British Committee of Germanischer Lloyd: the British Committee of Registro Italiano Navale and the British Technical Committee of the American Bureau of Shipping.

The Conventions and Protocols referred to in the Regulations may be obtained from the International Maritime Organisation, 4 Albert Embankment, London SE1 75R.
