Example 1 - leaving Las Palmas de Gran Canaria, bound


Reykjavik (Iceland)

(i) Receiving MS]


ALRS Vo!. 5, (NAVTEX section - see figure 3.1) shows Las
Palmas as station'!' - you need to programme your NAVTEX receiver
to receive Station I and also for the types of message you wish to
receive.
If your route north takes you out of range of the stations shown
on the coasts of Morocco, Spain, Portugal and Ireland, your next
NAVTEX station will be Reykjavik (station Identity 'R' for Iceland
coastal information - which also broadcasts coastal information for
the East Coast of Greenland using station Identity 'X').
The area between Las Palmas and Reykjavik NAVTEX services
will be covered by the Inmarsat SafetyNET service, available on your
Inmarsat-C equipment.
ALRS Vo!. 5 (SafetyNET section) shows that you will pass
through international NAVAREAlMETAREA 11 (2) and then I (1)
(figure 2.1). The table facing the world map shows that you can receive
navigation warnings on satellite AOR-East only. Weather information
is available on AOR-East and AOR-West (see Example 1 on page 14).
To receive both weather and navigation information, you need
to log-in to AOR-East for NAV/METAREA 11. Looking ahead to
NAV/METAREA I (i.e. when we cross 48° 27'N) we find that Nav
and Met information is available on AOR-East, with weather 'warnings
only' available on AOR-West. AOR-East will provide SafetyNET
information for the complete voyage.
(ii) Sea Area on SailinglSAR RespOnsibility
On a voyage from Las Palmas to Reykjavik, the maps in ALRS
Vo!. 5 (SAR Section) indicate that the responsible countries are Spain
(on leaving Las Palmas), then Portugal, then the United Kingdom, and
finally Iceland (figure 1.3). The maps also indicate that Las Palmas is
an 'AI' area and that the vessel will move into an A2 area, before
entering the Portugal SRR (Search and Rescue Region) which is, for
this voyage, almost entirely A3. Assuming the vessel keeps to the west
of the Ireland SRR, it will remain in an A3 area until it approaches the
Iceland SRR and which, for this voyage, is an A2 area.
