Learn how to prepare for COC and endorsement renewal or revalidation, including sea service, STCW, medical and document checks.
Introduction
Renewal should not be left until the last moment. A seafarer should check the expiry date, identify the correct renewal or revalidation route and confirm whether updated sea-service, training or medical evidence is required. The exact rules depend on the certificate and current requirements.
Renewal and revalidation are not always identical
The terms can describe different administrative or qualification processes. Use the terminology in the current official instructions for the certificate concerned.
Check the expiry date
Start with the date printed on the certificate or endorsement. If the document has already expired, do not assume that the normal renewal process still applies.
Prepare current supporting evidence
Depending on the application, relevant documents may include sea-service records, STCW refresher or other training evidence, medical documentation and the existing certificate.
Deal with discrepancies early
If your name, date of birth, rank or other information is incorrect, ask how the authority wants the correction handled before submitting the renewal application.
Lost certificates
If the original certificate is unavailable, follow the replacement procedure and then determine how the renewal or revalidation application should be combined or sequenced.
Avoid guaranteed timelines
Processing times can depend on the application and authority. Do not publish a fixed turnaround time unless the competent authority confirms it.
