SOLAS
Of all the international conventions dealing with maritime safety, the most important is the International Convention for the Safety of Life at Sea, better known as SOLAS, which covers a wide range of measures designed to improve the safety of shipping.
The Convention is also one of the oldest of its kind: the first version was adopted in 1914 following the sinking of the Titanic with the loss of more than 1,500 lives. Since then there have been four more versions of SOLAS. The present Convention was adopted in 1974 and entered into force in 1980.
This 2024 edition provides the full consolidated text of the SOLAS Convention, its 1988 Protocol and all amendments in force up to 1 July 2024.

MARPOL
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.

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 2022 consolidated edition provides 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 of the amendments that have been adopted by the Marine Environment Protection Committee (MEPC) with entry into force up to 1 November 2022.
