For attention of all Owners, Operators, and Masters of
Passenger, Cargo Vessels and Self-propelled mobile offshore
stThe Maritime Safety Committee (MSC) at its 81 session in May 2006 adopted the
amendment of the International Convention for the Safety of Life at Sea (SOLAS), 1974, introducing in Chapter V of the Convention a new regulation for the Long Range Identification and Tracking of Ships (LRIT) together with associated performance standards and functional requirements.
The obligations of ships to transmit LRIT information and the rights and obligations of Contracting Governments and of Search and Rescue services to receive LRIT information are established in regulation V/19-1.
Subject to the provisions of the following paragraphs 1.1 and 1.2, SOLAS regulation V/19-1, the new amendment, shall apply to the following types of ships engaged on international voyages:
; passenger ships, including high-speed passenger craft;
; cargo ships, including high-speed craft, of 300 gross tonnage1 and upwards;
; self-propelled mobile offshore drilling units, not on location.
The term “ship”, when used in the following paragraphs includes the passenger and cargo ships, high-speed craft and the mobile offshore drilling units that are subject to the provisions of this SOLAS regulation.
1 The gross tonnage to be used for determining whether a cargo ship or high-speed craft is required to comply with the provisions of SOLAS regulation V/19-1 shall be that determined under the provisions of the International Convention on Tonnage Measurement of Ships, 1969 irrespective of the date on which the ship or high-speed craft has been or is being constructed.
