For Indian seafarers holding a Certificate of Competency (COC) in the nautical discipline, revalidating the certificate periodically is crucial to continue professional maritime service under the Directorate General of Shipping (DG Shipping) regulations. This guide walks you through the comprehensive steps required for COC revalidation in India, ensuring regulatory compliance with STCW (Standards of Training, Certification and Watchkeeping) conventions and DG Shipping mandates.
Understanding COC Revalidation
The Certificate of Competency issued to seafarers confirms their capability and qualification to serve in specific maritime roles. Revalidation is mandatory every five years to verify that the seafarer has maintained their professional competence through required sea service, refresher courses, or training. It safeguards maritime safety by ensuring seafarers are updated with latest practices and skills.
Pre-Requisites for COC Revalidation

- Valid INDOS (Indian National Database of Seafarers) number as unique identity.
- Completion of required refresher and updating training courses approved by DG Shipping.
- Documented sea service or equivalently recognized shore service during the preceding five years.
- Medical fitness certification as per DG Shipping norms.
- Updated profile details, photographs, and signatures available on DG Shipping’s online portal.

Additional Important Points

- If you have insufficient sea service in the last 5 years but have shore-based marine service, this can be counted towards revalidation.
- Keep track of any inquiries or incidents that occurred during your sea service, as you may need to declare these during application.
- Ensure all uploaded documents, photos, and signatures meet DG Shipping’s quality and format standards to avoid rejection.
- In cases of eligibility queries or missing sea service records, liaise with respective MMD examiners with all original documents and prescribed fees.

FAQ’s on Indian COC (Nautical) Revalidations
How long is the Indian COC valid, and when should I apply for revalidation?

Can I submit my application for COC revalidation directly to MMD or only through a training institute?
Applications can be submitted online directly through the DG Shipping portal by the seafarer. It is not mandatory to apply only through the institute where you completed your refresher course.

You need to upload your current valid COC, continuous discharge certificate (CDC) pages as proof of sea service, certificates of completed refresher training courses, and medical fitness certificates.
