When the International Ship and Port Facility Security (ISPS) Code and amendments to the International Convention for the Safety of Life at Sea (SOLAS), 1974 were adopted by the International Maritime Organization (IMO) in December 2002, one of the issues that remained to be resolved was the long-range identification and tracking (LRIT) of ships. Resolution 3 of the 2002 SOLAS conference called on the IMO to carry out, as a matter of urgency, an impact assessment of the proposals to implement the LRIT of ships and develop and adopt appropriate performance standards and guidelines for the LRIT system. The establishment of the LRIT system aims to complement and support the implementation of the ISPS Code by detecting security threats and taking preventive measures against security incidents affecting ships or port facilities used in international trade. This chapter provides analysis of the status of the LRIT system and legal, administrative, and practical implications of its implementation for states. It also discusses concerns with respect to the draft technical standards for the LRIT system and concludes by highlighting the measures that the IMO and its contracting governments would need to take to advance the implementation of the LRIT system.
