Marine Log - December 2008 - (Page 44) SEMINAR | FLEET MAP MANAGEMENT: PROTECT YOUR FLEET WHAT’S A Quick Refresher As a safety and security measure, Long Range Identification and Tracking (LRIT) was introduced as a mandatory requirement for certain passenger, high-speed craft and cargo ships operating on international voyages under a regulation in SOLAS chapter V on Safety of Navigation. LRIT will transmit the ship's identity, location and date and time of the position to SOLAS Contracting Governments, who will be entitled to receive information on ships navigating within a distance not exceeding 1,000 nautical miles off their coast. This makes LRIT very different from AIS, not only in range, but also in that AIS is a broadcast system, whereas data derived through LRIT will be available only to the recipients who are entitled to receive such information. There is no interface between LRIT and AIS. LRIT is required on ships that operate on international voyages, including passenger ships, cargo ships (of 300 gross tonnage and upwards), and mobile offshore drilling units. The regulation also applies to high-speed craft. Ships built on or after Dec. 31, 2008 will be required to be fitted with LRIT. Ships built before that date will have a phased-in implementation schedule. LRIT is intended to be operational, with respect to the transmission of LRIT information by ships, from Dec. 31, 2008. The LRIT system consists of the shipborne LRIT information transmitting equipment, the Communication Service Providers, the Application Service Providers, the LRIT Data Centers (including any related Vessel Monitoring Systems), the LRIT Data Distribution Plan and the International LRIT Data Exchange.
