Duplication, Renewal, STCW Renewal, and Entry Level

 

Renewal
A credential may be renewed at any time during its validity and for one year after expiration. NOTE: Whenever an applicant applied for "renewal" of an endorsement as deck officer, engineer officer, or qualified rating more than 12 months after expiration, instead of meeting the requirements of 46 CFR 10.227 (d) (8), the applicant must demonstrate continued professional knowledge by completing a course or by passing the complete examination.

Duplicate
Upon request and without examination, a mariner may be issued a duplicate credential after submitting an application with an affidavit describing the circumstances of the loss. The duplicate issued will have the same wording, authority, and expiration date as the lost credential.
