Description
T-AIS information available to specific Member States having signed the relevant SLA with the SAFEMED countries (third countries with a coast in the Mediterranean Sea).
Data elements
- Fixed/static information: MMSI, Call sign and Ship Name, IMO number, Length and beam and Type of ship
- Dynamic information: Ship's position with accuracy indication and integrity status, Position timestamp in UTC, Type of electronic position fixing device, Course over ground (COG), Speed over ground (SOG), True heading, Navigational status and Rate of turn (ROT)
- Voyage related information: Ship's draught, Hazardous cargo (type) and Destination and ETA
Legal basis
Service Level Agreement (SLA) on sharing T-AIS information to be signed by SAFEMED countries
Conditions of Use for the participation of the SAFEMED and BCSEA Countries in MAREΣ in phase 2
Scope and source of data
Since 2002, the SOLAS Regulation V/19.2.4 requires that all ships of 300 gross tonnage (GT) and upwards engaged on international voyages, cargo ships of 500 GT and upwards not engaged on international voyages and passenger ships irrespective of GT must have an AIS Class A onboard at all times.
AIS data is gathered by shore-based stations owned by countries participating in SAFEMED project (i.e. Algeria, Egypt, Jordan, Israel, Libya, Lebanon, Morocco, Palestine and Tunisia).
Technical implementation
AIS works by automatically broadcasting tracking information at regular intervals via a Very High Frequency (VHF) transmitter built into the transponder to shore-based receiving stations. The AIS transponders work in an autonomous and continuous mode and, presently, the two VHF frequencies used are 161.975Mhz (AIS1, or channel 87B) and 162.025Mhz (AIS2, or channel 88B).
EMSA provides different alternative mechanisms to retrieve T-AIS from SAFEMED:
- System-to-system interface which allows exchange of data between EMSA and the national system;
- Graphical user interface providing access to T-AIS data;
- App for mobile devices (IMS App) providing access to current maritime picture on smart phones and tablets.
T-AIS data is available online for a minimum of 30 months from the reporting date. The data is archived for at least 5 years and may be provided upon request.
Conditions of access
In accordance with the Conditions of Use for the participation of the SAFEMED and BCSEA Countries in MAREΣ in phase 2, T-AIS data from SAFEMED are exchanged and made available to the MAREΣ participating States15, and T-AIS data of the MAREΣ participating States are made available to the SAFEMED participants.
