Security Duties
VPDSD (STCW VI/6)
Vessel Personnel with Designated Security Duties (VPDSD) is the security training required for crew assigned specific duties under the ship's security plan — controlling access, screening persons and baggage, patrolling, and responding to changing security levels. It sits above basic Security Awareness training and below the Vessel Security Officer endorsement.
Controlling regulation: STCW VI/6 · 33 CFR 104

Sea service requirement
No sea-service minimum. Earned by completing a USCG-approved VPDSD course. Crew with no designated security duties instead complete the shorter Security Awareness training (STCW VI/6-1).
Practical assessment: USCG-approved Vessel Personnel with Designated Security Duties course (STCW Regulation VI/6, Section A-VI/6).
Each day must be documented with a sea service letter showing vessel name, USCG Official Number, gross tonnage, route, position, dates, and total days served.

How to apply at the NMC
The application path is the same for every credential — only the documents and exams above change.
- 1
Complete the application form (CG-719B)
Fill out the Application for Merchant Mariner Credential (CG-719B). Small-vessel operators may document time on the Small Vessel Sea Service Form (CG-719S). List every endorsement you are applying for.
- 2
Assemble your supporting documents
Gather your TWIC, CG-719K medical certificate (within 12 months), CG-719P drug test (within 185 days), sea service letters, course completion certificates, and a copy of any current MMC. Missing or stale documents are the #1 cause of delays.
- 3
Submit to the National Maritime Center
Send the package to the NMC by email, mail, or fax, or hand it to a Regional Exam Center. Pay the applicable evaluation, examination, and issuance user fees (46 CFR 10.219) via Pay.gov.
- 4
NMC evaluation
An evaluator reviews your file against 46 CFR. If anything is missing you receive an Awaiting Information (AI) letter; once complete you get an Approval to Test (ATT) letter, valid 12 months, listing the exam modules you must pass.
- 5
Take any required exams at a REC
Schedule your modules at a Regional Exam Center within the ATT window. Each module is graded separately — passes are banked, and you retest only the modules you miss.
- 6
Issuance
Once evaluation, exams, and the safety/security (TWIC) check are all cleared, the NMC prints and mails your MMC. A credential is valid for five years.
Forms and fees are set by the U.S. Coast Guard. Confirm the current CG-719 forms and NMC user fees at the National Maritime Center before submitting.
