The following amendments to IMO Conventions entered into force on 1 January 2003: December 1998 amendments to the Seafarers' Training, Certification and Watchkeeping Code (aimed at improving minimum standards of competence of crews sailing on ships carrying solid bulk cargoes); June 2001 amendments to the International Convention for the Safety of Life at Sea (SOLAS), 1974, as amended and to the INF Code; and June 2001 amendments to the International Code of Safety for High-Speed Craft.

• The amendments concern section A-II/1 and A-II/2 under "Cargo handling and stowage at the operational and management levels" and relate to minimum standards of competence of crews, in particular relating to loading and unloading of bulk carriers, since these procedures have the potential to put undue stresses on the ship's structure, and inspection and assessment of damage to the cargo spaces, hatch covers and ballast tanks.
• The amendments to SOLAS Chapter VII - Carriage of Dangerous Goods - and to the International Code for the Safe Carriage of Packaged Irradiated Nuclear Fuel, Plutonium and High-Level Radioactive Wastes on Board Ships (INF Code) align both instruments with Amendment 30 to the International Maritime Dangerous Goods (IMDG) Code.
• The amendments to the International Code of Safety for High-Speed Craft (1994 HSC Code) bring the provisions for navigational equipment of the 1994 HSC Code in line with the relevant provisions of the 2000 HSC Code (which entered into force on 1 July 2002 for craft built after that date). The amendments relate to requirements for carriage of voyage data recorders and for the provision of automatic identification systems (AIS).
