(a) Certificates other than the Cargo Ship Safety
Construction Certificate, the Cargo Ship Safety Equipment Certificate
and any Exemption Certificate shall be issued for a period not exceeding
12 months. The Cargo Ship Safety Construction Certificate shall be
issued for a period not exceeding five years. The Cargo Ship Safety
Equipment Certificate shall be issued for a period not exceeding 24
months. Exemption Certificates shall not be valid for longer than
the period of the certificates to which they refer.
(b) No extension of the five-year period of validity
of the Cargo Ship Safety Construction Certificate shall be permitted.
(c) If a survey takes place within two months
before the end of the period for which a Cargo Ship Safety Radio Certificate
issued in respect of cargo ships of 300 gross tonnage and upwards,
but less than 500 gross tonnage, was originally issued, that certificate
may be withdrawn, and a new certificate may be issued which shall
expire 12 months after the end of the said period.
(d) If the ship at the time when a certificate,
other than that referred to in paragraph (b) of this regulation, expires
is not in a port of the State whose flag it is entitled to fly or
in which it is to be surveyed, the Administration may extend the certificate,
but such extension shall be granted only for the purpose of allowing
the ship to complete its voyage to the State whose flag it 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.
(e) No certificate shall be extended under the
provisions of paragraph (d) of this regulation for a longer period
than five months, and a ship to which an 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.
(f) A certificate, other than that referred to
in paragraph (b) of this regulation, which has not been extended under
the foregoing provisions of this regulation, may be extended by the
Administration for a period of grace up to one month from the date
of expiry stated on it.
(g) A certificate shall cease to be valid:
-
(i) if the inspections and surveys are not carried
out within the periods specified under regulations
7(a), 8, 9 and 10(a) of this chapter or as they may have been extended in accordance
with paragraphs (d), (e) or (f) of this regulation, or
-
(ii) upon transfer of the ship to the flag of
another Government. A new certificate shall only be issued when the
Government issuing the new certificate is fully satisfied that the
ship is in compliance with the requirements of regulation 11 (a) and (b) of this
chapter. In the case of a transfer between Parties, if requested within
three months after the transfer has taken place, the Government of
the Party whose flag the ship was formerly entitled to fly shall,
as soon as possible, transmit to the Administration copies of the
certificates carried by the ship before the transfer and, if available,
copies of the relevant survey reports.
