【关联题】 SOLAS, Chapter IX, and the ISM Code applies to ships, regardless of the date of construction, as follows:

Passenger ships, including passenger high-speed craft, not later than 1 July 1998; Oil tankers, chemical tankers, gas carriers, bulk carriers and cargo high-speed craft of 500 gross tons or more, not later than 1 July 1998; Other cargo ships and mobile

offshore drilling units (MODUs) of 500 gross tons or more, not later than 1 July 2002. The Code’s origins can be traced back to the late 1980s, when concern was growing about poor management standards in the shipping industry. In 1989, IMO adopted Guidelines on management for the safe operation of ships and for pollution prevention "to provide those responsible for the operation of ships with a framework for the proper development, implementation and

assessment of safety and pollution prevention management in accordance with good practice.” These guidelines were revised in November 1991 and the ISM Code itself was adopted as a recommendation in 1993. However,

after several years of practical experience, it was felt that the Code was so important that it should be mandatory. It was decided that the best way of achieving this would be through the International Convention for the Safety of Life at Sea, 1974 (SOLAS). This was done by means of amendments adopted on 24 May 1994, which added a new Chapter IX to the

Convention entitled Management for the safe operation of ships. The Code itself is not actually included in the Convention, but

is made mandatory by means of a reference in Chapter IX.
