 The Assembly

RECALLING Article 15(j) of the Convention on the International Maritime Organization concerning the functions of the Assembly in relation to regulations and guidelines concerning maritime safety and the prevention and control of marine pollution from ships,

 NOTING that the International Convention of Tonnage Measurement of Ships, 1969 (1969 Tonnage Convention) shall apply to existing ships as from 18 July 1994, under the provisions of article 3(2)(d) thereof,

 NOTING FURTHER that existing ships to which the 1969 Tonnage Convention shall apply on or after 18 July 1994 shall retain their then existing tonnages for the purpose of the application to them of relevant requirements under other existing international conventions,

 REALIZING that tonnages determined under the 1969 Tonnage Convention can be sufficiently different from those determined under the old national tonnage regulations to create confusion in connection with the application of:

 BEARING IN MIND that, although the 1974 SOLAS Convention and the other international conventions do not specifically define the gross tonnage of ships, the gross tonnage determined in accordance with the 1969 Tonnage Convention should be used for application of the provisions of these Conventions,

 BEARING IN MIND ALSO Resolution A.494(XII) on the Revised interim scheme for tonnage measurement for certain ships, Resolution A.540(13) on Tonnage measurement of certain ships relevant to the 1978 STCW Convention and Resolution A.541(13) on the Interim scheme for tonnage measurement for certain ships for the purposes of MARPOL 73/78,

 HAVING CONSIDERED the recommendation made by the Maritime Safety Committee at its sixty-third session and the Marine Environment Protection Committee at its thirty-sixth session,

  1. AGREES that for an existing ship, the keel of which was laid before 18 July 1982, having the gross tonnage determined in accordance with national tonnage rules, which was valid prior to the coming into force of the 1969 Tonnage Convention and which is stated under the REMARKS column of the International Tonnage Certificate (1969) for such a ship, the appropriate box in the pertinent Ship Safety Certificate, the International Oil Pollution Prevention Certificate or other such official certificates issued by the Administration may show only that old gross tonnage with one of the following footnotes:

  • “The above gross tonnage has been determined by the tonnage authorities of the Administration in accordance with the national tonnage rules which were in force prior to the coming into force of the International Convention on Tonnage Measurement of Ships, 1969”, or

  • See REMARKS column of the valid International Tonnage Certificate (1969)”,

  2. INVITES Member Governments and Governments of States parties to the aforementioned Conventions to take cognizance and to accept the use of this scheme for the purpose of application of the provisions of SOLAS 1974, MARPOL 73/78 and STCW 1978.
