193 The GMDSS has been developed by maritime nations represented by IMO. And it is the result
of their adoption of amendments made in 1988 to the 1974 International Convention on Safety
of Life at Sea. Based on recent developments in marine communications such as, satellite and digital technologies, the GMDSS is designed to ensure maximum availability of safety communications for all passenger ships and also on cargo ships of 300 gt and upwards engaged in international voyages. A. SOLAS amendments B. IMO regulations
C. SOLAS Conventions
D. all nations
