Operational Explanation

The extension up to three months to reach the survey port and short-voyage grace up to one month are distinct mechanisms subject to Convention conditions and Administration authorization.

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

  1. Confirm why the ship is away from the survey port at expiry.
  2. Check provision, certificate and authorisation.
  3. After arrival do not leave by virtue of the extension without a new certificate.
  4. Handle short-voyage grace separately.

Practical Example

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