Shipping Documentation

Going to sea for a living includes mastery of craft on many levels. A critically important part of it today is documentation. The documentation comes in many forms and from many sources. Below are links and files that will help members navigate the paperwork part of the occupation.

Credential and Documentation updates

The latest Credentialing information includes important extensions on Merchant Mariner Credentials, TWIC's, STCW endorsements and STCW med certs. Documentation is an ever-evolving part of a seagoing career with roots that go deep. Below this image of an antiquated certificate are some links to the latest information relating to current credentials:     


Extension of Credential Expirations

Due to the COVID-19 pandemic closures and processing delays, the Coast Guard and the TSA has extended the validity of credentials. MMC's expiring within a certain period are extended to December 31, 2020. Generally speaking, TWIC's are extended for 180 days. Important details are included in the following Marine Safety Information Bulletin and in TSA notice.

On Monday August 24, 2020, the Coast Guard extended again the expiration of MMC's and national endorsements until March 31, 2021. STCW med certs are extended until December 31, 2020.

Importantly, STCW Med Certs are extended only until 12/31/20. This relaxation applies to the expired med cert itself only: the actual medical standards that underpin the med cert remain in place.

Members with expiring documents should begin the renewal process anyway and in the meantime carry the expired credential as well as a copy of this notice to maintain compliance.

STCW Credentials

STCW guidance The International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (or STCW), sets international qualification standards for personnel on seagoing ships. There are a large range of STCW requirements. Basic Training, for example, is only one of many. These requirements have been incorporated into U.S. Regulation and Policy for certain personnel, including most SUP jobs. See U.S. Regulation, Policy, and STCW FAQs for more details about applicability, qualification, transition, and underlying national endorsement requirements.


NMC Policy and Regulations -- All manner of mariner policy and regulations is covered here. CFR's, policy letters, NVIC's, the Medical Manual, other guidance documents, the entire U.S. Code and much more. The United States Code (USC) is the official compilation and codification of federal statutes. Title 46 USC is directly related to shipping and our credentialing program. 46 CFR Parts 10, 11, 12,13,15, and 16 are directly related to the National Maritime Center's credentialing program. 33 CFR Navigation and Navigable Waters is also applicable and accessible here.

Some statutes are not self executing and require regulation to implement. Other regulations source from International Convention ratified by the United States.

 Maritime Commons -- This continuously updated official Coast Guard blog is sometimes easier to navigate especially for more updates and more recent information.
