The United States Coast Guard (USCG) National Maritime Center (NMC) awards credentials to fully qualified mariners to assure a safe, secure, economically viable and environmentally sound Marine Transportation System. There are generally two types of mariner credentials: National and International, and they are awarded in two primary operational departments, Deck and Engine. However, before any mariner credential is awarded, applicants must first attain a Transportation Worker Identification Credential (TWIC).
The International credentials are governed in compliance with Standards of Training, Certification, and Watchkeeping (STCW). These international standards (STCW) were first developed in 1978 when the international maritime community realized that human factors played a dominant role in the prevention of marine casualties. The last major revision to the international STCW Convention and Code were adopted in 2010 in Manila, Philippines and took effect on 1 Jan 2012.
General Application Requirements include drug test compliance, medical screening, First Aid and CPR certificates of training, and firefighting training. In addition to the general application requirements, the primary data elements that NMC evaluators need from military mariner applicants to assess their experience and suitability for National or STCW level credentials are Military Sea Service history and Vessel Information as described below:
MILITARY SEA SERVICE
Military sea service experience must be a reasonable equivalent to the service required of a merchant mariner who is seeking an identical license. Evaluations of military sea service require submission of a Transcript of Sea Service (TOSS) or a Sea Service Letter. Each service has a slightly different version of their Sea Service letter; this example shows U.S. Navy Sea Service Letter requirements. U.S. Army applicants can request a copy of their Sea Service history through the Sea Pay system.
NMC Regional Examination Centers may also require an official description of duties statement, letters of qualification, service record entries, or letters from former supervisors or commanding officers as well. Specific details about sea service requirements for the various different credentials can be found in 46 CFR Part 10 - Merchant Mariner Credential, and 46 CFR Part 12 - Requirements for Rating Endorsements. Additional details related to criteria for accepting military sea experience can be obtained from the Marine Safety Manual-Vol III, and Section 3 of the Military File Evaluation Manual.
VESSEL INFORMATION
Each Service also has corresponding vessel information.
U.S. Navy applicants can reference this U.S. Navy Vessel Information chart for details on Ship Type, Name, Hull number, Ship Class, GRI ITC Tonnage, GRT Tonnage, Horsepower, and Propulsion Type when completing their Sea Service Letter.
U.S. Army applicant’s Vessel information will be included in the Sea Pay letter they request for military sea service history.
