LRIT - Long-Range Identification and Tracking


Carriage of LRIT equipment

By adopting Resolution MSC 202(81) amending SOLAS Chapter V, Regulation 19, IMO   introduced a system for the long-range identification
and tracking (LRIT) of ships.

LRIT equipment has to be carried by all passenger vessels irrespective of their size and by cargo and other vessels >300 GT, in either case comprising all vessels engaged on international trade.

LRIT systems use shipboard LRIT equipment for the transmission of

  1. the identity of the ship
  2. the position of the ship (latitude and longitude), and
  3. the date and time of the position provided

to a LRIT Data Centre. Contracting Governments and search and rescue services which are entitled to receive such data obtain the LRIT data from LRIT Data Centres upon request.

Germany participates in the European LRIT-Data Centre, which is operated by the European Maritime Safety Agency (EMSA) and has been in operation since 1 July 2009.

Port states or coastal states approached by vessels consequently expect to have access to the data stored at the Data Centre. Therefore, the LRIT communication equipment should be permanently operational.

Latest information:
EMSA has drawn attention to the fact that vessels transmitting LRIT position data should NOT switch off transmissions in high-risk regions. Unlike, for example, AIS transmissions, the LRIT system uses point-to-point communication which is not generally received. LRIT information enables Flag States to provide better assistence to vessels in high-risk regions. Any case in which the LRIT system has been placed out of operation has to be notified to the Flag State (here: by the shipping company. See EMSA Technical Note (PDF, 89 KB).

The Conformance Test Report for LRIT equipment remains valid until the equipment is altered or replaced, the ship's flag changes or the certificate is withdrawn.  The Test Report includes a reference to the formal recognition of the Test ASP through BSH; the validity date referring to that recognition is effective with regard to the authorization to perform Performance Tests, it has no influence on the validity of Conformance Test Reports once issued. Existing Recognitions of Test-ASP’s are currently being renewed (see also Information about implementation of LRIT carriage requirements)
