Merchant Mariner's Document - MMD
License Description
The United States Coast Guard issues a Merchant Mariner's Document (MMD) to unlicensed personnel who support the operation of a vessel. Unqualified ratings are issued to entry level individuals who typically have little or no sea service for the following rating types: ordinary seaman (deck department), wiper (engineering department), or food handler (steward's department). Qualified ratings are issued based on previous sea service in a particular department or specialized training. Qualified ratings for members in the deck department are issued by rating type (e.g. Able Seaman) and vessel type restrictions (e.g. sail vessels or offshore supply vessels). Qualified ratings for members in the engineering department are issued by type (e.g. Qualified Member of the Engine Department) and specific rating (e.g. oiler, fireman/watertender, junior engineer, deck engine mechanic, or engineman). Other ratings are issued for specialized training or experience, such as Lifeboatman, Tankerman, or GMDSS At-Sea Maintainer. An MMD is valid for 5 years and may be renewed. Further information can be found at the USCG web site http://www.uscg.mil/stcw/index.htm and the Federal Code of Regulations (46 CFR12.02-11) at http://www.access.gpo.gov/nara/cfr/waisidx_02/46cfr12_02.html.
