About GMDSS and VHF Short Range Certificate (SRC)

The Global Maritime Distress and Safety System (GMDSS) and the VHF Short Range Certificate (SRC) are the two key marine radio qualifications for seafarers. The VHF SRC is a one-day course and examination covering VHF radio operation, DSC (Digital Selective Calling), distress procedures, and the GMDSS framework. It is mandatory for anyone in charge of a commercially operated vessel equipped with a VHF radio. The GMDSS General Operator Certificate (GOC) is a more advanced qualification required for deck officers on GMDSS-equipped commercial ships and covers MF/HF radio, INMARSAT, EPIRBs, SARTs, and full GMDSS operating procedures. Qualifications are issued through Ofcom-approved assessment bodies in the UK. Both the SRC and GOC are required for commercial vessel work — the appropriate level depends on vessel size and role.
