(Reg 10.5 of Annex I, Reg 10.5 of Annex II and Reg 8.5 of Annex IV, of MARPOL)
(1) If a ship in respect of which a NSW certificate is in force is not in a port in which it is to be surveyed at the time when the certificate expires, the Minister may extend the period of validity of the certificate by notice in writing.
(2) The Minister must only extend the period for the purpose of allowing the ship to complete its voyage to the port in which it is to be surveyed, and then only in cases where it appears proper and reasonable to do so.
(3) Without limiting subsection (2), a certificate must not be extended for a period longer than 3 months.
(4) An extension under this section ceases to apply once the ship arrives at the port at which it is to be surveyed.
