What is LRIT?
Long-Range Identification and Tracking (LRIT) system, a system that enables the global identification and tracking of ships using existing GMDSS equipment on board (INMARSAT-C).
A ship’s LRIT equipment must transmit position reports at 6-hour intervals unless a more frequent interval is requested remotely by an LRIT Data Center.
Why is the report required?
It us required under SOLAS chapter V Regulation 19.
Which ships are required to carry LRIT?
The following ships engaged on international voyages:
- Passenger ships
- Cargo ships of 300 gross tonnage and upwards
- Mobile offshore drilling units
How often must a vessel have a LRIT Conformance Test?
The LRIT conformance test certificate has no expiry date as long as the equipment remains the same. A retest may be required when:
- A vessel changes or upgrades the LRIT equipment
- A vessel changes flags
Note: ships shall automatically transmit the following long-range identification and tracking information:
- The identity of the ship
- The position of the ship
- The date and time of the position provided.
What information is contained on the Conformance Test Report?
- Name of ship
- Port of Registry
- Distinctive number or letters
- IMO number
- Maritime Mobile Service Identifier
- Gross Tonnage
- Sea areas in which the ship is certified to operate
- Sea areas for which this report is valid
- Application Service Provider conducting the test
- Details of the shipborne equipment used to transmit LRIT information (e.g., maker model, serial number and shipborne equipment identifier)
What does the report certify?
- That the equipment has been found to meet the requirement of the provision of regulations V/19-1.6 and V/19-1.7
- Is of a type approved by the Administration and meets the required performance standards
- Has undergone conformance testing in accordance with the procedures and provisions set out in MSC.1/Circ.1307, and has shown that it can operate within the tolerances of the acceptance criteria stated in the circular.
