7 LRIT Data Centre

  7.1 All LRIT Data Centres should:

  • .1 establish and continuously maintain systems which ensure, at all times, that LRIT Data Users are only provided with the LRIT information they are entitled to receive as specified in regulation V/19-1;

  • .2 collect LRIT information from ships instructed by their Administrations to transmit the LRIT information to the centre;

  • .3 obtain, when requested to provide LRIT information transmitted by ships other than those which transmit the information to the centre, LRIT information from other LRIT Data Centres through the International LRIT Data Exchange;

  • .4 make available, when requested to provide LRIT information transmitted by ships which transmit the information to the centre, LRIT information transmitted to the centre to other LRIT Data Centres through the International LRIT Data Exchange;

  • .5 execute requests received from LRIT Data Users for polling of LRIT information or for change(s) in the interval(s) of transmission of LRIT information by a ship or a group of ships transmitting the information to the centre;

  • .6 relay, when required, requests received from LRIT Data Users through the International LRIT Data Exchange to the other LRIT Data Centres for polling of LRIT information or for change(s) in the interval(s) of transmission of LRIT information by a ship or a group of ships not transmitting the information to the centre;

  • .7 execute requests received through the International LRIT Data Exchange from other LRIT Data Centres for polling of LRIT information or for change(s) in the interval(s) of transmission of LRIT information by a ship or a group of ships transmitting the information to the centre;

  • .8 upon request disseminate to LRIT Data Users the LRIT information they are entitled to receive in accordance with the agreed arrangements and notify the LRIT Data User and the Administration when a particular ship stops transmitting LRIT information;

  • .9 archive LRIT information from ships which transmit the information to the centre, for at least one year and until such time as the Committee reviews and accepts the annual report of the audit of its performance by the LRIT Coordinator. However, the archived LRIT information should provide a complete record of the activities of the centre between two consecutive annual audits of its performance;

  • .10 for LRIT information archived within the last 4 days, send the LRIT information within 30 min of receiving a request;

  • .11 for LRIT information archived between 4 and 30 days previously, send the LRIT information within 1 h of receiving a request;

  • .12 for LRIT information archived more than 30 days previously, send the LRIT information within 5 days of receiving a request;

  • .13 ensure using appropriate hardware and software, that LRIT information is backed-up at regular intervals, stored at suitable off-site location(s) and available as soon as possible in the event of disruption to ensure continuity of service;

  • .14 maintain a record of the ships which transmit LRIT information to the centre including name of ship, IMO Ship identification number, call sign and Maritime Mobile Service Identity (MMSI);

  • .15 use a standard protocol for communications and agreed protocols to connect with the International LRIT Data Exchange and the LRIT Data Distribution Plan server;

  • .16 use a standard secure transmission method with the International LRIT Data Exchange and the LRIT Data Distribution Plan server;

  • .17 use a secure authentication method with LRIT Data Users;

  • .18 use a standard and expandable message format for communicating with the International LRIT Data Exchange and the LRIT Data Distribution Plan server;

  • .19 use reliable connections (e.g., TCP) to ensure that the LRIT information is successfully received by the LRIT Data Centres;

  • .20 add the appropriate data identified in table 2 to each transmission of LRIT information collect by the centre; and

  • .21 have access to the current LRIT Data Distribution Plan and to earlier versions of the plan.

  7.2 All LRIT Data Centres should comply with the relevant provisions of the Technical specifications for communications within the LRIT systemfootnote and of the Technical specifications for the LRIT Data Distribution Plan and should take into account the relevant provisions of the Technical specifications for the International LRIT Data Exchange.

  7.3 All Regional or Cooperative LRIT Data Centres and the International LRIT Data Centre should only internally route LRIT information transmitted by ships entitled to fly the flag of the Contracting Governments establishing or participating such centres and should automatically maintain journal(s) for all of the internally routed LRIT information. The journal(s) should only contain message header information which should be used for audit and invoicing purposes. The journal(s) should be transmitted to the International LRIT Data Exchange at regular intervals in order to be combined with the journal(s) maintained by the International LRIT Data Exchange.

  7.4 Each LRIT Data Centre should:

  • .1 settle its financial obligations vis-à-vis the LRIT Data Centres which provide to it LRIT information and the International LRIT Data Exchange in a timely manner in accordance with the arrangements they have agreed;

  • .2 publish its charges, in currency to be decided by Contracting Government(s) establishing the centre and in Special Drawing Rights (SDR) together with the date(s) as from which the charges are effective, for:

    • .1 providing LRIT information transmitted by the shipborne equipment at preset intervalsfootnote,footnote;

    • .2 providing LRIT information transmitted by the shipborne equipment on demandfootnote;

    • .3 remotely configuring the shipborne equipment so as to transmit at interval other than the presetfootnote ones and for resetting the shipborne equipment to transmit at preset interval; and

    • .4 providing archived LRIT information which is the LRIT information received from a ship other than the last one,

and should update these as and when changes occur; and

  7.5 The performance of all LRIT Data Centres should be audited by the LRIT Coordinator.

  7.5.1 All LRIT Data Centres should cooperate and make available to the LRIT Coordinator the information required to enable the satisfactory completion of an audit of their performance.

  7.5.2 All LRIT Data Centres should settle their financial obligations vis-à-vis the LRIT Coordinator in a timely manner in accordance with the arrangements they have agreed.

  7.6 When providing LRIT information to LRIT Data Users, other than to a SAR service, LRIT Data Centres should:
