The Global Maritime Distress and Safety System (GMDSS) is a communication system for vessels. It is not just used for emergencies it can be used for vessel-to-vessel, vessel-to-shore and shore-to-vessel routine communications. To operate these systems, seafarers must hold a GMDSS Certificate of Competency (CoC), an internationally recognised qualification. This certification is required for radio communications on all vessels and ensures that seafarers, such as deck officers and radio operators, are trained to operate GMDSS equipment and handle critical safety and distress communications, as well as ship-to-ship and ship-to-shore transmissions.  

Detailed guidance on the GMDSS course approval process and the issuing of certificates is available in MIN 716 and MSN 1864 Amendment 1. Supplementary information can be found in MIN 643.

Application process

To apply for a GMDSS Certificate, seafarers must meet the requirements outlined in  MSN 1864 (M) Amendment 1 and complete training at an approved training provider. Upon successful completion of the course, to obtain a GMDSS Certificate or Endorsement, seafarers must complete the MSF 4354 form and submit it, along with the appropriate payment and the course completion certificate to gmdss@mcga.gov.uk 

Once the application is processed, the GMDSS Certificate will be sent to the address specified in the application form.
