New timetable for AIS requirements:

IMO Conference of Contracting Governments to the International Convention for the Safety of Life at Sea, 1974: 9 - 13 December 2002

A new, comprehensive security regime for international shipping is set to enter into force in July 2004 following the adoption by a week-long Diplomatic Conference of a series of measures to strengthen maritime security and prevent and suppress acts of terrorism against shipping. The Conference, held at the London headquarters of the International Maritime Organization (IMO) from 9 to 13 December, was of crucial significance not only to the international maritime community but the world community as a whole, given the pivotal role shipping plays in the conduct of world trade. The measures represent the culmination of just over a year's intense work by IMO's Maritime Safety Committee and its Intersessional Working Group since the terrorist atrocities in the United States in September 2001.

Modifications to Chapter V (Safety of Navigation) contain a new timetable for the fitting of Automatic Information Systems (AIS). Ships, other than passenger ships and tankers, of 300 gross tonnage and upwards but less than 50,000 gross tonnage, will be required to fit AIS not later than the first safety equipment survey after 1 July 2004 or by 31 December 2004, whichever occurs earlier. Ships fitted with AIS shall maintain AIS in operation at all times except where international agreements, rules or standards provide for the protection of navigational information."
