Reports should be made using VHF voice transmissions. However, ships equipped with
AIS (automatic identification system) can fulfill certain reporting requirements of the system
through the use of the universal AIS approved by the Organization.
A ship must give a short position report by voice or by AIS when entering the mandatory
ship reporting area. The full report may be given by voice or by non-verbal means. A ship may
elect, for reasons of commercial confidentiality, to communicate that section of the report which
provides information on cargo by non-verbal means prior to entering the ship reporting area.
When leaving port, the ship can give the full report to the ship reporting system by voice or by
non-verbal means.
3.1 Format3.1.1 The information given below is derived from the format-type given in paragraph 2 of the
appendix to resolution A.851(20).
3.2 Content3.2.1 A short report by voice or by AIS from a ship to the shore-based authorities should
contain the following information:
A | Name of the ship, call sign or IMO identification number (or MMSI for
transponder reports) |
B | Date and Time (UTC) |
C or D | Position (expressed in latitude and longitude or bearing to and distance
from a landmark) |
E and F | Course and speed of the ship |
3.2.2 A full report from a ship to the shore-based authorities by voice or by non-verbal means should contain the following information:
I | Destination and ETA |
L | Route information |
O | Vessel’s draught |
P | Hazardous cargo, class and quantity, if applicable |
Q or R | Breakdown, damage and/or deficiencies affecting the structure, cargo or
equipment of the ship or any other circumstances affecting normal
navigation in accordance with the provisions of the SOLAS and MARPOL
Conventions |
T | Contact information of ship’s agent or owner |
U | Ship’s deadweight tonnage |
W | Total number of persons on board |
X | Miscellaneous remarks, e.g. ice class, amount and nature of bunkers if
over 5000 tons, navigational status |
Note:On receipt of a position message, the system operators will establish the relationship
between the ship’s position and the information supplied by the position-fixing equipment
available to them. Information on course and speed will help operators to identify one
ship among a group of ships. This will be achieved automatically if AIS transponder is
used.
All VHF-, telephone-, radar-, AIS- and other relevant information will be recorded and
the records stored for 30 days.
3.3 Geographical position for submitting reports3.3.1 Eastbound traffic should make a report to TALLINN TRAFFIC when crossing the line
drawn from Bengtskär Lighthouse to 59°33.30’N 022°30’E to 59°10’N 021°30’E to Kõpu
Peninsula or when entering the ship reporting area from south.
3.3.2 Westbound traffic should make a short report to HELSINKI TRAFFIC when crossing
longitude 026°30’E or when entering the ship reporting area from north.
3.3.3 A full report to the nearest shore station should be made on departure from port.
3.3.4 Further reports should be made to the relevant shore station whenever there is a change of
navigational status or circumstance, particularly in relation to items Q and R of the
reporting format.
3.4 Crossing traffic3.4.1 Reports to the nearest shore station should be made on departure from a port within the
coverage area. Recognizing that ferries crossing between Helsinki and Tallinn generally
operate according to published schedules, special reporting arrangements can be made on
a ship-by-ship basis, subject to the approval of both HELSINKI TRAFFIC and
TALLINN TRAFFIC.
3.4.2 Further reports should be made to the relevant shore station whenever there is a change of
navigational status or circumstance, particularly in relation to items Q and R of the
reporting format.
3.4.3 On the area between Helsinki and Tallinn Lighthouses there is a heavy crossing traffic in
summer consisting mostly of high speed craft and recreational craft. In the area between
Porkkala Lighthouse and Naissaar there are recreational sailing activities in summer.
3.5 Authority3.5.1 The shore-based Authorities are:
Estonia: Estonian Maritime Administration
Finland: Finnish Maritime Administration
Russian Federation: Russian Maritime Administration
3.5.2 The Estonian, Finnish and Russian Authorities monitor shipping within the mandatory
ship reporting area of the Gulf of Finland by radar. This does not relieve ship masters of
their responsibility for the navigation of their ship.
