The International Convention for the Prevention of Pollution from Ships, 1973 (MARPOL Convention), is concerned with preserving the marine
environment through the prevention of pollution by oil and other harmful substances and the minimization of accidental discharge of such
substances. Its technical content is laid out in six Annexes, the first five of which were adopted by the 1973 Convention, as modified by a 1978
Protocol. These Annexes cover pollution of the sea by oil, by noxious liquid substances in bulk, by harmful substances in packaged form, by
sewage from ships, and by garbage from ships. Annex VI was adopted by a further Protocol in 1997 and covers air pollution from ships.

The 2017 consolidated edition aims to provide an easy and comprehensive reference to the up-to-date provisions and Unified
Interpretations of the Articles, Protocols and Annexes of the MARPOL Convention, including the incorporation of all the amendments that have
been adopted by the Marine Environment Protection Committee (MEPC).
