In order to avoid penalties by border authorities or be the reason for detention or delay of the vessel, you are requested always to carry your Seaman’s Passport with you. The reason is that the Bulgarian Seaman’s Discharge Book is not an identity document. It serves only for documentation of seagoing service regarding the type of the vessel and the length of service. The Bulgarian identity document issued for the purposes of Convention 108 of the International Labour Organisation is the Seaman’s Passport.
For more information regarding the matter, please visit the website of the Bulgarian Maritime Administration.
