Long Range Identification and Tracking (LRIT) is a global monitoring system of the ship’s movements. Ships are required to fit a system that automatically transmits information, such as identity, position and the date and time of the position at time of transmission. Ships are required to have such a system installed on the first radio inspection day after 31 December 2008, according to MSC.202 (81).
The following ships (engaged on international voyages) are required to implement LRIT:
- All passenger ships, including high speed craft
- Cargo ships, including high speed craft of 300 gross tonnage and above
- Mobile offshore drilling units
