Certificate of Competence (CoC): start with what you hold

A Certificate of Competence (CoC) records competency for a stated capacity or rank. The issuing authority, rank, validity and supporting training documents are central to understanding the next licensing or endorsement pathway.

Certificate of Endorsement (CoE) and CoC endorsements

An original Certificate of Competence (CoC), Certificate of Endorsement (CoE), CoC endorsement and Seaman Book are different documents. Identifying the required service helps avoid preparing the wrong supporting records.

Seaman Book, STCW and supporting documents

Passport details, Seaman Book records, sea service, STCW certificates and other training evidence may be relevant depending on the service. Current requirements should be confirmed for the specific case.

Keep career and documentation planning connected

Training, renewals and endorsements often affect one another. Planning the next requirement early can reduce last-minute disruption.

Important: Maritime requirements can change and may vary by administration, vessel or seafarer profile. Confirm current requirements before acting on a specific case.
