CLS, your LRIT partner

Data Centre Solutions

Each Flag state is obliged to establish a National LRIT Data Centre or to join a Regional or Cooperative Data Centre. The Flag also has to formally appoint an Application Service Provider (ASP). This ASP manages the communications between the ship, the Communication Centre provider (CSP) and the Data Centre (DC).

The DC collects all of the Flag’s LRIT information (such as the ships’ positional data and their identities) and is connected to the International LRIT system via the International Data Exchange (IDE) using a specific LRIT communications protocol.

In addition, these centres shall be capable of communicating amongst themselves and exchanging position reports on request. A ship having notified a port of impending entry (NOA) can be tracked by that particular port thanks to this system. Next to that, it will be possible for Contracting Governments to track any ship within a 1,000 nautical mile zone of its coastline, no matter what flag it is flying.

According to the Transitional Arrangements in  MSC.1/Circ.1299 , every DC will have to be operational on the 1st of July 2009 at the latest. While the 31 December 2008 implementation date remains as written in the Regulation V/19-1, the design, construction, testing and integration of components of the system are still in progress. As a result, transitional arrangements to cover the time period from 31 December 2008 to 30 June 2009 have been adopted (see MSC.1/Circ.1299 to learn more).
