SOLAS Convention

The International Convention for the Safety of Life at Sea (SOLAS) is an international maritime treaty which requires Signatory flag states to ensure that ships flagged by them comply with minimum safety standards in construction, equipment and operation. The current version of the SOLAS Convention is the 1974 version, known as SOLAS 1974, which came into force on 25 May 1980. As of March 2016, SOLAS 1974 has 162 contracting States, which flag about 99% of merchant ships around the world in terms of gross tonnage.

The SOLAS Convention in its successive forms is generally regarded as the most important of all international treaties concerning the safety of merchant ships.

The first version of SOLAS was passed in 1914 in response to the sinking of the RMS Titanic. It prescribed numbers of lifeboats and other emergency equipment along with safety procedures, including continuous radio watches. The 1914 treaty never entered into force due to the outbreak of the First World War.

Further versions were adopted in 1929 and 1948.

The 1960 Convention was adopted on 17 June 1960 and entered into force on 26 May 1965. It was the fourth SOLAS Convention and was the first major achievement for International Maritime Organization (IMO). It represented a considerable step forward in modernising regulations and keeping up with technical developments in the shipping industry.

In 1974 a completely new Convention was adopted to allow SOLAS to be amended and implemented within a reasonable time scale, instead of the previous procedure to incorporate amendments, which proved to be very slow. Under SOLAS 1960, it could take several years for amendments to be come into force since countries had to give notice of acceptance to IMO and there was a minimum threshold of countries and tonnage. Under SOLAS 1974, amendments enter into force via a tacit acceptance procedure – this allows an amendment to enter into force on a specified date, unless objections to an amendment are received from an agreed number of parties.

The 1974 SOLAS came into force on 25 May 1980, 12 months after its ratification by at least 50 countries with at least 50% of gross tonnage. It has been updated and amended on numerous occasions since then and the Convention in force today is sometimes referred to as SOLAS, 1974, as amended.
