If you pass the seaman's certificate, it will not be permanent. All certificates are permanent except the service book. Generally, other certificates are five years, and you need to run at least once every five years. Otherwise, even if it is overdue, you must be promoted within five years. Brothers who haven't been promoted and sailed, please try to update before the expiration, so that they can be released for another five years. It doesn't matter if it expires. Just attend a compulsory training. Time is short and convenient.

How long is the seaman's certificate valid?
