• (2) An existing ship, other than an existing fishing boat, of less than 24 metres length, already registered in the State, may retain its tonnages as ascertained in accordance with the revoked Regulations.

ASCERTAINMENT OF TONNAGE

Method of measurement

• (2) The gross and net tonnages shall be determined in accordance with Regulations 7 and 8, provided that in the case of novel types of craft with constructional features which render the application of the provisions unreasonable or impracticable, the gross and net tonnages shall be determined as required by the Minister.

• (3) All measurements used in the calculations of volumes shall be taken and expressed in metres to the nearest centimetre.

• (4) Gross and net tonnages shall be expressed as whole numbers, decimals being rounded off downwards.

Calculation of volumes

• (2) Volumes of appendages shall be included in the total volume.

• (3) Volumes of spaces open to the sea shall be excluded from the total volume.

• (4) The method and accuracy of the calculations shall be to the satisfaction of the Minister and shall be sufficiently detailed to facilitate checking.

Gross tonnage

GT = K1V,

where—

V = total volume of all enclosed spaces of the ship in cubic metres, and

K1 = 0.2+0.02 log10V or as specified in Schedule 2.

Net tonnage

where—

VC = total volume of cargo spaces in cubic metres,

K2 = 0.2+0.02 log10Vc or as specified in Schedule 2, and

K3 = [image omitted];

in the above formula for determining the net tonnage—

GT	=	gross tonnage calculated in accordance with Regulation 7,
D	=	moulded depth amidships in metres,
d	=	moulded draught amidships in metres,
N1	=	number of passengers in cabins with not more than 8 berths,

Tonnages (segregated ballast oil tankers and deck cargoes)

K1 x Vb,

where—

K1 = 0.2+0.02 log10V or 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 6.

EXPLANATORY NOTE

(This note is not part of the instrument and does not purport to be a legal interpretation)

These regulations give effect to the International Convention on Tonnage Measurement of Ships 1969, and Council Regulation (EEC) No 2930/86 as amended which deals with the tonnage measurement of fishing vessels. Additionally the Regulations extend the application of Council Regulation (EEC) No 2930/86 as amended to all ship types.

Part 2 applies to all Irish registered ships of 15 metres in length and over.

Provision is made for net and gross tonnages to be measured in accordance with the Regulations (Regulations 6 to 9) and for the Minister or an authorised certifying authority to issue or cancel tonnage certificates (Regulations 10 and 11).

Where segregated ballast tanks complying with the International Convention for the Prevention of Pollution from Ships 1973 are provided in oil tankers, including combination carriers, an entry may be made on the International Tonnage Certificate (1969) in accordance with the International Maritime Organisation Resolution A388(X) indicating the total tonnage of those tanks (Regulation 9(1)).

Certain existing ships of 24 metres in length and over, as specified, may continue to have their tonnages ascertained in accordance with the Regulations as set out in the Fourth Schedule and Appendices thereto of the Merchant Shipping (Tonnage) Regulations 1984 ( S.I. No. 369 of 1984 ) (Part 5).

An existing ship, other than an existing fishing boat, of less than 24 metres length, already registered in the State, may retain its tonnages as ascertained in accordance with the Regulations, which were in force prior to the coming into force of these Regulations (Regulation 4(2)).

Part 3 applies to all ships of less than 15 metres in length overall registered under the Mercantile Marine Act 1955 and fishing boats registered under the Mercantile Marine Act 1955 and Chapter 6 of the Sea-Fisheries and Maritime Jurisdiction Act 2006 or only under Chapter 6 of the Sea-Fisheries and Maritime Jurisdiction Act 2006 .

An existing ship, other than an existing fishing boat, of less than 15 metres length overall already registered in the State, may retain its tonnages as ascertained in accordance with the Regulations that were in force prior to the coming into force of these Regulations (Regulation 13(2)).

Part 4 deals with the treatment of foreign ships whilst within the State or the territorial waters of the State, and provides for the inspection of their tonnage certificate (Regulation 18).

The Regulations also implement the Interim Scheme for the Tonnage Measurement for Certain Ships, adopted by the International Maritime Organisation in Resolution A.494 (XII). This Scheme permits the use of gross tonnage ascertained in accordance with the provisions as set out in the Fourth Schedule and Appendices thereto of the Merchant Shipping (Tonnage) Regulations 1984 ( S.I. No. 369 of 1984 ) to be used for the application of the provisions of Regulations made under the International Convention for the Safety of Life at Sea, 1974 and the Protocol of 1978 relating thereto (Regulation 20).

The Merchant Shipping Tonnage Regulations 1984 are being revoked under the new Regulations, save that existing ships as specified above may continue to have their tonnages ascertained under the Fourth Schedule of the 1984 Regulations.
