Artikel 13

1. This Protocol shall enter into force twelve months following the date on which ten States including four States each with not less than one million units of gross tanker tonnage have deposited instruments of ratification, acceptance, approval or accession with the Secretary-General of the Organization.
2. However, any Contracting State to the 1971 Fund Convention may, at the time of the deposit of its instrument of ratification, acceptance, approval or accession in respect of this Protocol, declare that such instrument shall be deemed not to be effective for the purposes of this Article until the end of the six-month period in Article 31 of the Protocol of 1992 to amend the 1971 Fund Convention. A State which is not a Contracting State to the 1971 Fund Convention but which deposits an instrument of ratification, acceptance, approval or accession in respect of the Protocol of 1992 to amend the 1971 Fund Convention may also make a declaration in accordance with this paragraph at the same time.
3. Any State which has made a declaration in accordance with the preceding paragraph may withdraw it at any time by means of a notification addressed to the Secretary-General of the Organization. Any such withdrawal shall take effect on the date the notification is received, provided that such State shall be deemed to have deposited its instrument of ratification, acceptance, approval or accession in respect of this Protocol on that date.
4. For any State which ratifies, accepts, approves or accedes to it after the conditions in paragraph 1 for entry into force have been met, this Protocol shall enter into force twelve months following the date of deposit by such State of the appropriate instrument.
