Change of Flag and the Shadow Fleet: What Changes for Surveys and Certificates
At a flag transfer the printed expiry date of old certificates cannot be relied upon: each instrument has its own transfer provision and new-Administration documents must be effective when required.
Operational Explanation
At a flag transfer the printed expiry date of old certificates cannot be relied upon: each instrument has its own transfer provision and new-Administration documents must be effective when required.
Regulatory Reference
Instrument-specific transfer provisions: SOLAS, MARPOL, Load Lines, Tonnage, ISM, ISPS and MLC.
Scope of Application
Many certificates cease at transfer; transitional validity exists only where expressly provided.
Procedure / How to Complete It
- Build a matrix for each certificate/authorisation.
- Exchange survey reports and records between Administrations where provided.
- Plan issue/effectiveness under the new flag.
- Do not promise overlap from the old printed expiry date.
- Check class, insurance and trading consequences separately.
Practical Example
A Tonnage Certificate may have a specific transition; that does not automatically extend SOLAS or MARPOL certificates.
What Typically Goes Wrong
Saying issue before previous certificates expire as a general continuity guarantee.
