Operational Explanation

Regulatory Reference
A.1207(34) and the exact extension provision for the certificate concerned.
Scope of Application
Only where the Convention permits; it is not a general commercial allowance.
Procedure / How to Complete It
- Confirm why the ship is away from the survey port at expiry.
- Check provision, certificate and authorisation.
- After arrival do not leave by virtue of the extension without a new certificate.
- Handle short-voyage grace separately.

An authorised extension allows completion of the voyage to the survey port, not further voyages after arrival.
