Radio certificate


Here, you can read about the certificates in maritime radio services. The page contains information about  how to acquire a certificate and what to do if you have lost a certificate or need to renew a certificate. Furthermore, you can read about ITU certificates and find an overview of the certificate requirements for the various radio systems.

Acquisition and initial issue

In order to acquire a certificate in maritime radio services (GMDSS (GOC), GMDSS (ROC) or LRC), you must complete a radio course offered by a nautical training institution or by a teacher.

You can find a nautical training institution or a teacher here.

When you have passed the test, you can apply for your first certificate here.

Lost certificate

If you loose your (GMDSS (GOC), GMDSS (ROC) or LRC) certificate during its period of validity, you can apply for a copy here. (in Danish)

Renewal

In order to renew your radio certificate (GOC or ROC), you can apply for the first certificate here.

GMDSS (GOC) General Operator ´s Certificate - also referred to as GMDSS (SGOC)

The certificate has a period of validity of five years. In order to renew your certificate, you must document either 12 months' seagoing service during the last five years or 3 months' seagoing service during the last six months on board ships fitted with a GMDSS radio. If you are a teacher at a training institution, your application for renewal will be individually considered.

If you hold a valid GOC you can have it replaced for an LRC.

GMDSS (ROC) Restricted Operator´s Certificate - also referred to as GMDSS (SROC)

The certificate has a period of validity of five years. In order to renew your certificate, you must apply for a renewal.

LRC Long Range Certificate - Certificate for operating maritime MF, HF and VHF radio systems

An LRC does not have any date of expiry and therefore need not be renewed. An LRC can only be used for radio systems on board fishing vessels and recreational craft.

SRC Short Range Certificate - Certificate for operating VHF radio systems

An SRC certificate does not have a date of expiry and therefore need not be renewed. An SRC certificate is a radio certificate that you must have if you buy a recreational craft with radio equipment on board. You can read more and apply for the certificate here.

ITU certificates (IGOC and IROC)

Previously, GMDSS (GOC) and GMDSS (ROC) were issued in two different versions. One of the versions met only the requirements of the ITU Radio Regulations and was, therefore, referred to as IGOC or IROC. The other version met both the ITU requirements and some supplementary requirements of the STCW Convention and is therefore not referred to as SGOC or SROC. As of 1 September 2011 (order no. 939), IGOC and IROC are no longer issued.

If you want to replace an ITU certificate (IGOC and IROC) for a certificate with an STCW endorsement (SGOC and SROC), you must complete the course STCW supplementary module radio, which is offered by nautical schools or by teachers.

IROC can be used only on board recreational craft.

You can find a nautical school or a teacher here.
