In 2003, ILO also issued a set of guidelines as a complement to the work undertaken by IMO and under the Basel Convention on shipbreaking.21 The Guidelines, which are not legally binding, are the most comprehensive guide covering all aspects of occupational health and safety related to ship dismantling. They are designed to assist those having responsibilities for health and safety in shipbreaking operations, including yard owners and competent authorities, to implement the relevant provisions of ILO standards, codes of practice and other guidelines on occupational safety and health and working conditions. Their main objectives are to: (a) contribute to the protection of shipbreaking workers from workplace hazards and to the elimination and control of work-related injuries and diseases, ill-health and incidents; and (b) to assist and facilitate the improved management of occupational safety and health issues in or about the workplace. 4. IMO convention on ship recycling 53. In December 2005, the IMO Assembly requested the Marine Environment Protection Committee to develop a new legally binding instrument on ship recycling, which would regulate: (a) the design, construction, operation and preparation of ships so as to facilitate safe and environmentally sound recycling; (b) the operation of ship-recycling facilities in a safe and environmentally sound manner; and (c) the establishment of an appropriate enforcement mechanism for ship recycling, incorporating certification and reporting requirements.22 After four years of negotiations, the Hong Kong International Convention for the Safe and Environmentally Sound Recycling of Ships was adopted at the International Conference on the Safe and Environmentally Sound Recycling of Ships, held in Hong Kong, China, from 11 to 15 May 2009. 21 Safety and health in shipbreaking: Guidelines for Asian countries and Turkey, 2004. 22 Resolution A.981 (24).
