Long Range Identification and Tracking (LRIT) system

Vessels that are required to use LRIT must report new or renewed LRIT certificates to the Norwegian Coastal Administration (NCA).

The International Maritime Organisation (IMO) has decided that the LRIT system is only mandatory for the following ships in international waters:

  • Passenger ships, including high-speed passenger crafts
  • Cargo ships, including high-speed crafts, of 300 gross tonnage and upwards
  • Mobile offshore drilling units

The following are exempt from using LRIT:

  • Military vessels
  • Fishing vessels
  • Vessels operated exclusively within the Sea Area A1 (small volume of coastal shipping)

LRIT is internationally enshrined in Chapter V of the 1974 SOLAS Convention, and was unanimously adopted on 19 May 2006 in Resolution MSC.202 (81).

LRIT in Norway

  • The Norwegian Coastal Administration is the National Competent Authority (NCA) for LRIT in Norway, and operates the Norwegian part of the international LRIT database on behalf of the Norwegian authorities.
  • The Norwegian Coastal Administration registers, corrects and updates data on LRIT-liable vessels sailing with the Norwegian flag in the European LRIT database.
  • The Norwegian Coastal Administration provides systemic access to public authorities that wish to use data from the system for carrying out government tasks.
  • LRIT was introduced in Norway in 2009, and is a closed system used only by national public authorities.
  • Public authorities use the LRIT monitoring system in traffic monitoring, to locate vessels in need of assistance and surrounding vessels in connection with rescue operations, control and intervention against vessels that pose a danger to maritime safety or a threat to the coastal state, and monitoring of vessels involved in illegal, unreported or unregistered fisheries or other illegal activities.
  • The Norwegian Maritime Authority has the authority to enforce compliance with the LRIT regulations on board.

User Access to the LRIT System

The Norwegian Coastal Administration is the National Competent Authority (NCA) with responsibility for introducing the technical concept of the identification and tracking of vessels and the distribution of LRIT information to other public authorities.

The system is only available for use by public authorities. Sharing Norwegian LRIT data with international organisations for a certain period is subject to agreement.

About LRIT

Long Range Identification and Tracking (LRIT) is a global satellite-based system for real-time identification and tracking of specific types of vessels. LRIT is based on data from INMARSAT and IRIDIUM.

Vessels have LRIT equipment on board that automatically transmits information about their identity and position as well as the date/time every six hours via satellite to the EU’s LRIT database.

The system is operated by the European Maritime Safety Agency (EMSA).
