Certificate extensions

Certain statutory certificates may be extended by the Administration under the conditions and limits stated in the applicable convention, commonly to allow the ship to reach a port of survey. The three-month mechanism must not be applied generically to every document in this catalogue. Always identify the certificate-specific provision and calculate any permitted period from the date required by that provision.
