Liberia updates requirements for Long Range Identification and Tracking of Ships

Maritime authority of Liberia has updated the requirements related to Long Range Identification and Tracking of Ships (LRIT) due to a number of ships registered under the Liberian flag having old or improperly functioning shipborne LRIT equipment and/or old LRIT conformance tests.

This has resulted in many ships being unable to transmit consistent LRIT information due to equipment failure, so in order to ensure crew, ship, and environmental safety, a conformance test is required for all new installations of shipborne LRIT equipment.

For existing installations, a test is required at the time of change of flag (from a different Administration to the Liberian flag) or at the time of re-registration under the Liberian flag to a different owner under the Liberian flag.

For Inmarsat C shipborne equipment, it's needed to ensure that Macro Encoded Message 11 (MEM-11) and Polling & Data Reporting (PDR) functions are enabled.

For Iridium shipborne equipment, all models listed are suitable for LRIT without further configuration, while IsatM2M satellite service is withdrawn and ships with this equipment installed are no longer compliant with LRIT regulations.
