NVIC 21-14: Sea service credit for STCW VSO endorsements
Last reviewed: October 14, 2026
This Coast Guard guidance change notice revises NVIC 21-14 on STCW endorsements for Vessel Security Officer, Vessel Personnel with Designated Security Duties, and Security Awareness. Its main change lets sea service on certain military and government owned or operated vessels count toward the VSO sea service requirements. The NVIC is guidance, not a regulation.
Applies toThe text addresses mariners seeking STCW endorsements as Vessel Security Officer (VSO), Vessel Personnel with Designated Security Duties (VPDSD), and for Security Awareness (SA).
What it says
The Coast Guard will use this NVIC and the named sections of Title 46 Code of Federal Regulations to decide whether mariners qualify for STCW endorsements as VSO, VPDSD, and SA.
“The Coast Guard will use this NVIC and Title 46 Code of Federal Regulations (CFR)”
The Coast Guard has determined that sea service on certain government owned or operated vessels of at least 100 GRT counts toward the sea service requirements in 33 CFR 104.215(d)(1)(v)(A) and 104.215(d)(1)(v)(B).
NVIC 21-14 b.“sea service onboard certain government owned or government operated vessels of at least 100 GRT counts toward the sea service requirements”
A mariner can demonstrate the operational experience needed for the VSO endorsement under 33 CFR 104.215(d)(1)(v)(B) by combining up to 5 months of military sea service, 30 days minimum sea service on government owned or operated vessels of 100 GRT or on vessels subject to 33 CFR 104.105, and the knowledge requirements in 33 CFR 104.215.
NVIC 21-14 b.“combining (1) up to 5 months of military sea service, (2) 30 days minimum sea service on government owned or operated vessels of 100 GRT”
This guidance is not a regulation and does not impose legally-binding requirements on any party.
“It is not intended to, nor does it impose legally-binding requirements on any party.”
A mariner who meets the requirements for a superior security endorsement has the merchant mariner credential endorsed for that endorsement and all subordinate endorsements.

a.
After publication of reference (a), the Coast Guard became aware of the need to address the question of whether sea service acquiredon military and government-owned or operated vessels should be allowed to be used to qualify fora STCW endorsement as VSO.This change notice revises NVIC 21-14toindicate that the Coast Guard has determined sea service accrued aboard certain military and government owned or operated vessels may be credited toward the sea service requirements in 33 CFR 104.215(d)(1)(v)(A)and 104.215(d)(1)(v)(B) to qualify for a STCW endorsement as VSO.

The regulations at 46 CFR 10.232(d)(1) allow the use of military service towards credentials when the Coast Guard determines it is equivalent to sea service acquired on merchant vessels.
Additionally, many government owned and operated vessels are operated similarly to a merchant vessel.
The purpose of the sea service requirements for aSTCW endorsement as VSO is to ensure that the mariner is familiar with general merchant vessel operations.
The Coast Guard has determined that sea service onboard certain government owned or government operated vessels of at least 100 GRT counts toward the sea service requirements in 33 CFR 104.215(d)(1)(v)(A) and 104.215(d)(1)(v)(B) as it achieves familiarity with merchant vessel operations.
Additionally, the Coast Guard has determined that by combining (1) up to 5 months of military sea service, (2) 30 days minimum sea service on government owned or operated vessels of 100 GRT or on vessels subject to 33 CFR 104.105, and (3) the knowledge requirements in 33 CFR 104.215, the mariner can demonstrate the necessary operational experience to qualify for the VSO endorsement under 33 CFR 104.215(d)(1)(v)(B). c.
This policy supports the intent of 10 U.S.C. 2015 and Executive Order 13860 of March 4, 2019, Supporting the Transition of Active Duty Service Members and Military Veterans Into the Merchant Marine, by supporting practices that ensure that members of the United States Armed Forces receive appropriate credit for their military training and experience toward merchant mariner credentialing requirements.

BACKGROUND. a.
Regulation VI/6 of reference (a) sets forth minimum requirements for security-related training and instruction for seafarers.
DISTRIBUTION – SDL No. 162 a b c d e f g h i j k l m n o p q r s t u v w x y z A B X X X X X C X X D X X E X X F G H NAVIGATION AND VESSEL INSPECTION CIRCULAR NO. 21-14 b.
In 2009, the Coast Guard added a regulation in 46 CFR 15.1113(a) that requires a person serving as VSO on a seagoing vessel to hold a VSO endorsement. c.
The International Maritime Organization (IMO) amended the STCW Convention and STCW Code on June 25, 2010.
These amendments entered into force for all ratifying countries on January 1, 2012.
Specifically, the 2010 amendments to the STCW Convention and Code added security-related endorsements for VPDSD, and for SA. d.
The Coast Guard published a final rule on December 24, 2013, (78 FR 77796) that implements reference (a), including the 2010 amendments.
That rule includes provisions for the STCW security endorsements.
This rule became effective on March 24, 2014.
The Coast Guard is publishing this NVIC to provide guidance on complying with the new regulations. 5.
DISCUSSION. a.
The STCW requires that certain seafarers hold endorsements as VSO, VPDSD, or SA depending on the scope of their shipboard security duties.
The IMO published Circular STCW.7/Circ.17 in June 2011, advising administrations and port state control authorities that mariners may comply with section 13 of the International Ship and Port Facility Security Code (ISPS Code) instead of Regulation VI/6 of the STCW Convention until January 1, 2014.
Recognizing the challenges of ensuring that mariners will hold the endorsements by this date, the IMO has promulgated a circular STCW.7/Circ.21, advising port state control officers, recognized organizations and recognized security organizations that until July 1, 2015, even if a seafarer does not hold an endorsement for security awareness training or for seafarers with designated security duties, it would be sufficient to accept compliance with Section 13 of the International Ship and Port Facility Security (ISPS) Code, Part A.
With a free public account, Circular STCW.7/Circ.21 can be accessed online at http://www.imo.org/OurWork/Circulars/Pages/IMODOCS.aspx > Circulars > STCW > STCW.7.
After that date, pursuant to Circular STCW.7/Circ.17, mariners on vessels of 500 gross tons or more sailing beyond the boundary line established by 46 CFR Part 7 must hold the STCW endorsement appropriate for their shipboard security duties, except mariners serving on vessels that have been determined to be otherwise exempt from, or not subject to, further requirements of STCW under 46 CFR 15.105(f) and (g). b.
In addition to the endorsement requirements for vessel personnel, all contractors, whether part-time, full-time, temporary, or permanent, must have knowledge of the requirements in 33 CFR 104.225, through training or equivalent job experience.
Vessel owners and operators must maintain records documenting this requirement and produce those records to the Coast Guard upon request (46 CFR 15.1113(f)). c.
The security training requirements in the STCW were developed as a progression where “security-awareness” is the lowest level of training and “vessel security officer” (VSO) demands the highest level of training.
Under this progression, VSO training meets the requirements for VPDSD, and the VPDSD meets the requirements for security NAVIGATION AND VESSEL INSPECTION CIRCULAR NO. 21-14 awareness.
Therefore, for example, mariners who completed VSO training would be eligible for any position with a training requirement at the VSO level or lower.
A mariner who meets the requirements for a “superior” security endorsement will have their merchant mariner credential (MMC) endorsed for the superior endorsement as well as all subordinate endorsements. d.
This NVIC establishes the policy regarding VSO, VPDSD, and SA.
Enclosure (1) discusses specific requirements for security endorsements, Enclosure (2) provides guidance on approval of courses leading to security endorsements.
Enclosure (3) contains relevant excerpts from the STCW Convention and STCW Code, these are provided for information only. 6.
