PART 2Communication procedures
THIS PA RT OF THE GUIDE identifies which radio/satellite communications
equipment may be used, and the voice/messaging procedures for Routine,
day-to-day, communications (Chapter 4) and for Distress (Mayday),
Urgency (Pan Pan) and Safety (Securite) communications (Chapter 5).
Where non-GMDSS equipment may be used as an alternative to
GMDSS equipment for some routine tasks, that equipment is also
identified.
As with Part 1, this part assumes that the user has a basic
understanding of the equipment listed below (but you don't have to know
how to use the controls - which are explained in Part 3 to learn the
procedures included in this Part).
The emphasis is on selecting appropriate equipment for the task
at hand; identifying channels/frequencies to be used; and using the correct
(alerting/voice/messaging) procedures for exchanging information.
Shore-based facilities are identified using Admiralty Lists of Radio
Signals (ALRS) Volume 1 (Coast Radio Stations, and Ship Reporting
Systems); Volume 5 (GMDSS SAR facilities); and Volume 6 (Ports, Pilots,
and Vessel Traffic Services).
The assumed (marine radio/satcom) equipment is:- Marine VHF Radio with Digital Selective Calling (DSC).
Marine MF /HF Radio with Digital Selective Calling (DSC) and
SSB Telex Over Radio (TORlNBDP).- NAVTEX.
- Inmarsat-C (including SafetyNET).
Inmarsat-A and/or Inmarsat-B.
Cospas-Sarsat EPIRB. - Search & Rescue (radar) Transponders (SART).
- Handheld VHF Radio for Onboard Communications (all channels).
- Handheld VHF Liferaft sets (ChI6, Ch06 and Ch13 only).
The vessel is assumed to carry Admiralty List of Radio Signals
Volumes 1,2,3,5 and 6; ITU List of Ship Stations; ITU List of Callsigns
and Numerical Identities; and the International Aeronautical and
Maritime Search And Rescue (IAMSAR) Manual Volume 3.
