46 CFR § 10.229 - Replacement of lost merchant mariner credentials.
(a) Upon request and without examination, a mariner may be issued a duplicate credential and medical certificate after submitting an application with an affidavit describing the circumstances of the loss. The Coast Guard will only issue the duplicate credential, MMC and/or medical certificate, after confirming the validity of the mariner's credentials and the validity of the mariner's TWIC.
(c) If a person loses a credential by shipwreck or other casualty, a duplicate credential will be issued free of charge. The term “other casualty” includes any damage to a ship caused by collision, explosion, tornado, wreck, flooding, beaching, grounding, or fire; or personal loss associated with a federally declared natural disaster.
(f) Applications for duplicate credentials will not be subject to a criminal record review.
