Bulletin 160: LRIT – General information
General Information regarding the new LRIT service
Long Range Identification Tracking (LRIT) is a method by which Flag States may know where their ships are located anywhere in the world and any other Flag State’s vessels transiting their waters. The standard accuracy is that of a ship position 6 hours old; in cases of special concern the frequency can be increased to instant ship positions. These changes should they be required are made from the Barbados Data Centre; no adjustments have to be made onboard with the ships equipment.
Conformance Test Report (CTR)
The equipment to be used for these transmissions of LRIT information is tested by a BMSR Approved Application Service Provider (ASP). On successful completion of the tests the vessel is left with a LRIT Conformance Test Report (CTR) confirming that the vessel’s equipment is standing by ready for activation from the BMSR Data Centre. The ship’s copy of the CTR must be kept safely with the ship’s papers.
LRIT Compliance Test Certificate
Once the CRT is produced to the BMSR a LRIT Compliance Certificate will be issued to the ship for keeping with the CRT. Neither the CRT or Compliance Certificates have an expiry date therefore they do not have to be periodically renewed.
New LRIT equipment tests will be required if:-
- The ships equipment fails requiring the replacement of equipment.
- A ship changes Flag and the new Flag State does not recognise the ASP of the previous Flag State.
It is important that the ship board equipment is not switched off or tampered with in any way as this may affect the transmission of position reports and in turn cause problems with Port or Coastal State authorities.
If your vessel is laid up or in dry dock for any period over 3 weeks you must notify BMSR so that the Data Centre can be made aware of the reason for the static plots of the vessel.
