16.2.2 Radio installations

  16.2.2.1 Table 1 illustrates the radio installations to be carried to fulfil the functional requirements for sailing at different distances from a safe haven.

Radio Equipment Distance from safe haven - nautical miles
Up to 30 Up to 60 Up to 150 Unlimited
VHF Radiotelephone with Digital Selective Calling (DSC) One One One One
MF/HF Radiotelephone with Digital Selective Calling (DSC) None None One1 One1
INMARSAT Ship Earth Station None None One1 One1
NAVTEX2 receiver None None One2 One2
Notes:

1. An INMARSAT ship earth station OR an MF/HF radiotelephone with DSC may be fitted for operations over 60 miles from a safe haven. When a vessel operates north of 70° North, or south of 70° South, i.e. polar regions, an INMARSAT Ship Earth and MF/HF is required due to lack of coverage also, IRIDIUM is recommended.

2. If the vessel is sailing in an area where an international NAVTEX service is not provided then the NAVTEX receiver should be supplemented by an INMARSAT enhanced group calling system.

  16.2.2.2 Example:

As an illustration, the minimum equipment to be installed on a vessel engaged on world-wide operations south of 70 North and north of 70 degrees South would be:

  • one VHF radiotelephone with DSC;

    one INMARSAT-C ship earth station;

    one NAVTEX receiver.

Note also the requirement for the carriage of two way radiotelephone sets, EPIRB's and SART's given in section 13 table 1.
