issued for a period specified by the Administration, which shall not exceed five

shore terminal under the jurisdiction of the Party to the Convention whose 
flag the ship is entitled to fly, the certificate may be extended by the Administra- 
tion, 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 surveyed 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.

graph (2) of this Regulation may be extended by the Administration for a 
period of grace of up to one month from the date of expiry stated on it. 
(5) A Certificate shall cease to be valid if significant alterations have taken 
place in the construction, equipment, fittings, arrangements, or material required 
without the sanction of the Administration, except the direct replacement of such 
equipment or fittings, or if intermediate surveys as specified by the Administra- 
tion under Regulation 4(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 paragraph (7) of this 
Regulation. 
(7) Upon transfer of a ship to the flag of another Party, the Certificate shall 
remain in force for a period not exceeding five months provided 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 Government of the Party whose flag the ship was 
formerly entitled to fly shall transmit to the Administration a copy of the Certifi- 
cate carried by the ship before the transfer and, if available, a copy of the rele- 
vant survey report.
