(2) If a ship at the time when the Certificate expires is not in a port 

 or offshore terminal under the jurisdiction of the Party to the Conven- 

 tion whose flag the ship is entitled to fly, the Certificate may be ex- 

 tended by the Administration, but such extension shall be granted only 

 for the purpose of allowing the ship to complete its voyage to the 

 State whose flag the ship is entitled to fly or in which it is to be sur- 

 veyed and then only in cases where it appears proper and reasonable to 

 do so. 



(3) No Certificate shall be thus extended for a period longer than 

 five months and a ship to which such extension is granted shall not on 

 its arrival in the State whose flag it is entitled to fly or the port in 

 which it is to be surveyed, be entitled by virtue of such extension to 

 leave that port or State without having obtained a new Certificate. 



(4) A Certificate which has not been extended under the provisions 

 of paragraph (2) of this Regulation may be extended by the Adminis- 

 tration for a period of grace of up to one month from the date of ex- 

 piry stated on it. 



(5) A Certificate shall cease to be valid if significant alterations 

 have taken place in the structure, equipment, fittings, arrangements 

 and material required by this Annex without the sanction of the Ad- 

 ministration, except the direct replacement of such equipment or fit- 

 ting for the purpose of repair or maintenance or if intermediate sur- 

 veys as specified by the Administration under Regulation 10(1) (c) of 

 this Annex are not carried out. 



(6) A Certificate issued to a ship shall cease to be valid upon transfer 

 of such a ship to the flag of another State, except as provided in para- 

 graph (7) of this Regulation. 



(7) Upon transfer of a ship to the flag of another Party, the Certifi-, 

 cate shall remain in force for a period not exceeding five months pro- 

 vided that it would not have expired before the end of that period, or 

 until the Administration issues a replacement certificate, whichever is 

 •earlier. As soon as possible after the transfer has taken place the Gov- 

 ernment of the Party whose flag the ship was formerly entitled to fly 

 shall transmit to the Administration a copy of the Certificate carried 

 by the ship before the transfer and, if available, a copy of the relevant 

 survey report.
