Chapter 10 Communications
Satellite communications equipment normally operates at 1.6 GHz and the power levels generated are not sufficient to present an ignition hazard. Satellite communications equipment may therefore be used to transmit and receive messages whilst the ship is in port.
Communications procedures:
10.1 Are instructions for operating the digital selective calling (DSC) and satellite communications
equipment in an emergency clearly displayed?
10.2 Are the vessel’s call sign and Inmarsat ship station identity clearly marked on the radio
installation?
10.3 Can officers demonstrate a satisfactory understanding of how to operate the equipment in an
emergency?
10.4 Is a continuous listening watch maintained on VHF channel 16? 10.5 Are officers aware of the requirements for position updating on two-way communications
equipment?
