The Long Range Identification and Tracking (LRIT) system is a designated International Maritime Organization (IMO) system designed to collect and disseminate vessel position information received from IMO member States ships that are subject to the International Convention for the Safety of Life at Sea (SOLAS).
Liberia maintains a National Data Center (NDC). The NDC monitors Liberian-flagged ships that are 300 gross tons or greater on international voyages.
LRIT provides an enhanced level of Maritime Domain Awareness that is the first of its kind. LRIT is a satellite-based, real-time reporting mechanism that allows unique visibility to position reports of vessels.
The LRIT system consists of the ship borne LRIT information transmitting equipment, Communications Service Providers (CSPs), Application Service Providers (ASPs), LRIT Data Centers, the LRIT Data Distribution Plan (DDP) and the International LRIT Data Exchange. Certain aspects of the performance of the LRIT system are reviewed or audited by the LRIT Coordinator acting on behalf of the IMO and its Contracting Governments.
To ensure compliance with the provisions of SOLAS, the Maritime Security Department supervises the conformance test results of LRIT data and issues a Conformance Certificate. A conformance test is required for all shipborne LRIT equipment, in order to ensure the equipment, as fitted onboard, complies with the provisions of SOLAS Regulation V/19-1.6 and the LRIT revised performance standards and functional requirements.
The Conformance test shall be conducted by one of the Liberian Administration authorized Testing Application Service Provider (Testing ASP) whose details are outlined below:
**For issuance of LRIT certificate, please request that the test results, from one of the 3 authorized ASP’s, are forwarded to our Administration in .xml file format.
For further details regarding LRIT, including requirements and procedures for obtaining a certificate, please reference our Marine Notice, ISP-003 (Rev. 06/22).
