The Directive 2002/59/EC of the European Parliament and of the Council of 27 June 2002 requires the Member States (MSs) to provide themselves with appropriate equipment and shore-based installations for receiving and utilizing the AIS information transmitted by the vessels. The Member States agreed to implement common regional systems hosted and developed by one of them. EMSA and the Italian Coast Guard subscribed, since 2009, a Service Level Agreement (SLA) by which Italy is responsible for the hosting, maintenance, operation, and monitoring of the Mediterranean AIS Regional Server (MAREΣ) and its connection with SafeSeaNet. Part of SafeSeaNet, MAREΣ (Mediterranean AIS Regional Exchange System) officially started to run on 1st January 2008; currently it allows the AIS information sharing among Mediterranean EU countries (Portugal, Spain, France, Italy, Malta, Slovenia, Greece, Cyprus, Romania, Bulgaria, Croatia) and non-EU which agreed to share AIS data between themselves (e.g., Jordan, Morocco, and Montenegro).
