Global Maritime Distress Safety System - Licensing of Operators

Licensing of Operators

National maritime authorities may issue various classes of licenses. The General Operator’s Certificate is required on SOLAS vessels operating also outside GMDSS Sea Area A1, while a Restricted Operator’s Certificate is needed on SOLAS vessels operated solely within GMDSS Sea Area A1,

Long Range Certificate may be issued, and is required on non-SOLAS vessels operating outside GMDSS Sea Area A1, while a Short Range Certificate is issued for non-SOLAS vessels operating only inside GMDSS Sea Area A1.

Finally there is a restricted radiotelephone operator's certificate, which is similar to the Short Range Certificate but limited VHR DSC radio operation. Some countries do not consider this adequate for GMDSS qualification.

In the United States four different GMDSS certificates are issued. A GMDSS Radio Maintainer's License allows a person to maintain, install,and repair GMDSS equipment at sea. A GMDSS Radio Operator's License is necessary for a person to use required GMDSS equipment. The holder of both certificates can be issued one GMDSS Radio Operator/Maintainer License. Finally, the GMDSS Restricted License is available for VHF operations only within 20 nautical miles (37 km) of the coast. To obtain any of these licenses a person must be a U.S. citizen or otherwise eligible for work in the country, be able to communicate in English, and take written examinations approved by the Federal Communications Commission. Like the amateur radio examinations, these are given by private, FCC-approved groups. These are generally not the same agencies who administer the ham tests. Written test elements 1 and 7 are required for the Operator license, and elements 1 and 7R for the Restricted Operator. (Passing element 1 also automatically qualifies the applicant for the Marine Radiotelephone Operator Permit, the MROP.)

For the Maintainer license, written exam element 9 must be passed. However, to obtain this certificate an applicant must also hold a General radiotelephone operator license (GROL), which requires passing commercial written exam elements 1 and 3 (and thus supersedes the MROP). Upon the further passing of optional written exam element 8 the ship radar endorsement will be added to both the GROL and Maintainer licenses. This allows the holder to adjust, maintain, and repair shipboard radar equipment.

Until March 25, 2008 GMDSS operator and maintainer licenses expired after five years but could be renewed upon payment of a fee. On that date all new certificates were issued valid for the lifetimes of their holders. For those still valid but previously issued with expiration dates, the FCC states:

Any GMDSS Radio Operator's License, Restricted GMDSS Radio Operator's License, GMDSS Radio Maintainer's License, GMDSS Radio Operator/Maintainer License, or Marine Radio Operator Permit that was active, i.e., had not expired, as of March 25, 2008, does not have to be renewed.

Since an older certificate does show an expiration date, for crewmembers sailing internationally it may be worth paying the fee (as of 2010 it was $60) to avoid any confusion with local authorities.

Finally, to actually serve as a GMDSS operator on most commercial vessels the United States Coast Guard requires additional classroom training and practical experience beyond just holding a license.
