32.1 §1
Distress communications rely on the use of terrestrial MF, HF and VHF
radiocommunications and communications using satellite techniques. Distress communications
shall have absolute priority over all other transmissions. The following terms apply:
The distress alert is a digital selective call (DSC) using a distress call format,
in the bands used for terrestrial radiocommunication, or a distress message
format, in which case it is relayed through space stations.
The distress call is the initial voice or text procedure.
The distress message is the subsequent voice or text procedure.
The distress alert relay is a DSC transmission on behalf of another station.
The distress call relay is the initial voice or text procedure for a station not
itself in distress. (WRC-07)
Maday
32.13C §9B
1) The distress call sent on the frequency 156.8 MHz (VHF channel 16)
shall be given in the following form:
the distress signal MAYDAY, spoken three times
the words THIS IS
the name of the vessel in distress, spoken three times
the call sign or other identification
the MMSI (if the initial alert has been sent by DSC). (WRC-07)
32.13D
2) The distress message which follows the distress call should be given in
the following form:
the distress signal MAYDAY
the name of the vessel in distress
the call sign or other identification
the MMSI (if the initial alert has been sent by DSC)
the position, given as the latitude and longitude, or if the latitude and
longitude are not known or
if time is insufficient, in relation to a known geographical location
the nature of the distress
the kind of assistance required
any other useful information. (WRC-07)
32.13E § 9C DSC procedures use a combination of automated functions and manual intervention to
generate the appropriate distress call format in the most recent version of Recommen-
dation ITU-R M.541. A distress alert sent by DSC consists of one or more distress alert attempts
in which a message format is transmitted identifying the station in distress, giving its last
recorded position and, if entered, the nature of the distress. In MF and HF bands, distress alert
attempts may be sent as a single-frequency attempt or a multi-frequency attempt on up to six
frequencies within one minute. In VHF bands, only single-frequency call attempts are used. The distress alert will repeat automatically at random intervals, a few minutes apart, until an
acknowledgement sent by DSC is received. (WRC-07)
Urgency
33.12 §6
1) The urgency call should consist of:
the urgency signal PAN PAN, spoken three times;
the name of the called station or “all stations”, spoken three times;
the words THIS IS;
the name of the station transmitting the urgency message, spoken three times;
the call sign or any other identification;
the MMSI* (if the initial announcement has been sent by DSC),
followed by the urgency message or followed by the details of the channel to be used
for the message in the case where a working channel is to be used.
Safety
33.33 §1
§ 17 The safety signal consists of the word SECURITE. In radiotelephony, it shall
be pronounced as in French. 33.34
§ 18 1) The safety call format or the safety signal indicates that the calling
station has an important navigational or meteorological warning to transmit. (WRC-07) 33.34A
2) Messages from ship stations containing information concerning the
presence of cyclones shall be transmitted, with the least possible delay, to other mobile stations
in the vicinity and to the appropriate authorities through a coast station, or through a rescue
coordination centre via a coast station or an appropriate coast earth station. These transmissions
shall be preceded by the safety announcement or call. (WRC-07) 33.34B
3) Messages from ship stations, containing information on the presence of
dangerous ice, dangerous wrecks, or any other imminent danger to marine navigation, shall be
transmitted as soon as possible to other ships in the vicinity, and to the appropriate authorities
through a coast station, or through a rescue coordination centre via a coast station or an
appropriate coast earth station. These transmissions shall be preceded by the safety announ-
cement or call. (WRC-07)
33.35
§ 19 1) The complete safety call should consist of:
the safety signal SECURITE, spoken three times;
the name of the called station or “ALL STATIONS”, spoken three times;
the words THIS IS;
the name of the station transmitting the safety message, spoken three times;
the call sign or any other identification;
the MMSI (if the initial announcement has been sent by DSC),
followed by the safety message or followed by the details of the channel to be used for the
message in the case where a working channel is to be used.
Silence
32.45 § 28
1) The rescue coordination centre responsible for controlling a search and
rescue operation shall also coordinate the distress traffic relating to the incident or may appoint
another station to do so. (WRC-07)
32.46
2) The rescue coordination centre coordinating distress traffic, the unit
coordinating search and rescue operations9 or the coast station involved may impose silence on
stations which interfere with that traffic. This instruction shall be addressed to all stations or to
one station only, according to circumstances. In either case, the following shall be used: 32.47
a)
in radiotelephony, the signal SILENCE MAYDAY, pronounced as the
French expression “seelonceall stations, m'aider”;
32.48
b)
in narrow-band direct-printing telegraphy normally using forward-error
correcting mode, the signal SILENCE MAYDAY. However, the ARQ mode may be
used when it is advantageous to do so. 32.49
§ 29 Until they receive the message indicating that normal working may be
resumed (see No. 32.51), all stations which are aware of the distress traffic, and which are not
taking part in it, and which are not in distress, are forbidden to transmit on the frequencies in
which the distress traffic is taking place. 9 32.46.1
In accordance with the International Convention on Maritime Search and Rescue (1979) this is the
on-scene commander (OSC) or the coordinator surface search (CSS).
Fini
32.51 § 31 When distress traffic has ceased on frequencies which have been used for
distress traffic, the station controlling the search and rescue operation shall initiate a message for
transmission on these frequencies indicating that distress traffic has finished. (WRC-07)
32.52§ 32
In radiotelephony, the message referred to in No. 32.51 should consist of:
the distress signal MAYDAY (Hier nur einmal)
the call ALL STATIONS, spoken three times
the words THIS IS;
the name of the station sending that message, spoken three times;
the call sign or other identification of the station sending the message;
the time of handing in of the message;
the MMSI (if the initial alert has been sent by DSC), the name and the call-sign
of the mobile station which was in distress; Achtung: Die MMSI steht hier wieder vorne (Bruch in der Logik)?
Nein, über die Zeitangabe und die MMSI finden Sie den Call in den Received Distress-Calls in ihren DSC-Controller.
the words SEELONCE FEENEE pronounced as the French words “silence fini”. (WRC-07)
Maday Relay
32.19C
4) However, a ship shall not transmit a distress alert relay to all ships by
digital selective calling on the VHF or MF distress frequencies following receipt of a distress
alert sent by digital selective calling by the ship in distress. (WRC-07)
32.19D
5) When an aural watch is being maintained on shore and reliable ship-to-
shore communications can be established by radiotelephony, a distress call relay is sent by
radiotelephony and addressed to the relevant coast station or rescue coordination centre on the
appropriate frequency. (WRC-07)
32.19E
6) The distress call relay sent by radiotelephony should be given in the following form:
the distress signal MAYDAY RELAY, spoken three times;
ALL STATIONS or coast station name, as appropriate, spoken three times;
the words THIS IS;
the name of the relaying station, spoken three times;
the call sign or other identification of the relaying station;
the MMSI (if the initial alert has been sent by DSC) of the relaying station
(the vessel not in distress). (WRC-07)
32.19F
7) This call shall be followed by a distress message which shall, as far as
possible, repeat the information contained in the original distress alert or distress message.
(WRC-07)
32.19G
8) When no aural watch is being maintained on shore, or there are other
difficulties in establishing reliable ship-to-shore communications by radiotelephony, an
appropriate coast station or rescue coordination centre may be contacted by sending an
individual distress alert relay by DSC, addressed solely to that station and using the appropriate
call formats. (WRC-07)
32.19H
9) In the event of continued failure to contact a coast station or rescue
coordination centre directly, it may be appropriate to send a distress call relay by radiotelephony
addressed to all ships, or to all ships in a certain geographical area. See also
No. 32.19C. (WRC-07)
32.53A Cancellation of an inadvertent distress alert (WRC-07) 32.53B § 32A 1) A station transmitting an inadvertent distress alert or call shall cancel the
transmission. (WRC-07)
32.53C 2) An inadvertent DSC alert shall be cancelled by DSC, if the DSC
equipment is so capable. The cancellation should be in accordance with the most recent version
of Recommendation ITU-R M.493. In all cases, cancellations shall also be transmitted by
radiotelephone in accordance with 32.53E. (WRC-07)
32.53D 3) An inadvertent distress call shall be cancelled by radiotelephone in
accordance with the procedure in 32.53E. (WRC-07)
32.53E 4) Inadvertent distress transmissions shall be cancelled orally on the
associated distress and safety frequency in the same band on which the distress transmission was
sent, using the following procedure:
the call “ALL STATIONS”, spoken three times;
the words THIS IS;
the name of the vessel, spoken three times;
the call sign or other identification;
the MMSI (if the initial alert has been sent by DSC);
PLEASE CANCEL MY DISTRESS ALERT OF time in UTC.
Monitor the same band on which the inadvertent distress transmission was sent and
respond to any communications concerning that distress transmission as appropriate. (WRC-07)

Situation:
Sie haben einen Distress-Alert empfangen und keine Bestätigung durch eine Küstenfunkstelle gehört Auch wenn es ihnen lange erscheint, warten sie mindestens 10 Minuten, bevor sie einen Mayday-Relay absetzen
Sie haben einen Notfall beobachtet (z.B. rote Rakete) und keinen Notruf empfangen.
Senden Sie keinen DISTRESS per DSC wenn Sie eine solche Situation vorliegt (d.h. Sie sich nicht selbst in Not befinden).
(Siehe auch 32.19.C)
Besser ist es Bremen Rescue oder ein MRCC direkt per DSC anzufunken. Ansonsten wird Ihre Position bei DSC-MAYDAY mitgeliefert.
Ein Digital-Selectiv-Call hat eine grössere Reichweite als CH16, deshalb nehmen u.U. Schiffe Kurs auf ihre Position die ja automatisch mit übermittelt wird.
Neuere DSC-Controller haben u.U. einen Menüpunkt für "Mayday-Relay" bei dem aber dann eine Ziel-MMSI angegeben werden muss und kein allgemeiner DSC-Mayday ausgelöst wird.
Nur wenn Sie wiederholt keinen Kontakt zum MRCC herstellen konnten, ist angebracht einen Distress Relay auszusenden (32.19.H)
Eingabe in DSC-Controller
Achtung: in der Realität sind die Cursortasten u.U. mehrfach zu drücken.
Bitte klicken sie die blauen Auswahlen an, da keine Eingaben in den Controller möglich sind.

Am 24. Sept. 2013 12:50 hörten wir einen derartigen Notruf, bei dem Bremen Rescue nach
zwei Anglern suchte, die am Vorabend nicht zurückgekehrt waren.
Da sich ja Bremen Rescue nicht selbst in Not befand, wurde der Notruf vom Bremen Rescue per DSC
angekündigt und dann als Mayday-Relay ausgestrahlt. Damit ist die Situation klar, denn es wird kein Schiff Kurs auf Bremen Recue nehmen.
