GMDSS General Operator's Certificate (GOC)

10 day taught course. MCA / STCW approved.

NAFC Course Code: N34


The GMDSS General Operator's Certificate (GOC) is the qualification required by deck officers and other radio operators on GMDSS-equipped ships operating anywhere in the world.

The Global Maritime Distress and Safety System

The Global Maritime Distress and Safety System (GMDSS) is an internationally agreed system of communications equipment and procedures to ensure that vessels anywhere in the world will be able to receive assistance when they are in distress.

Larger ships (> 300 GT) sailing on international voyages are obliged to carry specific types of radios and other communication equipment that are specified in the GMDSS (including satellite communications equipment and emergency beacons).

GMDSS systems are not compulsory for smaller vessels (including fishing boats and recreational craft) but GMDSS-compatible systems are recommended. Most modern radio equipment incorporates GMDSS features, such as as Digital Selective Calling. All radio courses, therefore, cover aspects of the GMDS System.
