Upon the expiration of the validity period, the seaman's certificate may apply to the maritime administrative agency with corresponding management authority for a certificate of competency before it becomes effective. Crew card is a certificate issued by the maritime department to the crew of a country or an international sailing ship, which is checked and registered by the frontier inspection personnel at the time of entry and exit. It is an effective document for the crew of an international sailing ship. If qualification replacement is required, the qualifications required for replacement need to be manually entered into the system one by one, and the information page and qualification page of the service book are uploaded to the system as attachments. If the qualification involves entry and exit, please take photos and upload the entry and exit signature of the seaman's card before applying for replacement. When the seaman's certificate expires, it is necessary to re-collect the information of the new seaman's certificate. I can log in to the maritime administrative agency to apply for a new seaman's card with my original ID card and bareheaded electronic photo (two-inch white background, monochrome dark coat, no epaulettes, and my forehead and ears exposed) within six months.

The deck personnel working on the tugboat should correspond to the power of the tugboat. The validity period of the certificate of competency is increased by three months, that is, the certificate of competency can be replaced normally within three months after its expiration. If it is more than three months, it needs testing, simulator training and knowledge updating.
