The International Convention for the Safety of Life at Sea (SOLAS) is an international maritime safety treaty. 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 the treaty 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.
Chapters of SOLAS are :
Chapter I: A General Provisions
Surveying the various types of ships and certifying that they meet the requirements of the convention.
Chapter II-1: A Construction A Subdivision and stability, machinery and electrical installations.
The subdivision of passenger ships into watertight compartments so that after damage to its hull, a vessel will Remain afloat and stable.
Chapter II-2: A Fire protection, fire detection and fire extinction.
Fire safety provisions for all ships with detailed measures for passenger ships, cargo ships and tankers.
Chapter III: A Life-saving appliances and arrangements.
Life-saving appliances and arrangements, including requirements for life boats, rescue boats and life jackets according to type of ship.
Chapter IV: A Radio communications.
The Global Maritime Distress Safety System (GMDSS) requires passenger and cargo ships on international voyages to carry radio equipment, including satellite Emergency Position Indicating Radio Beacons (EPIRBs) and Search and Rescue Transponders (SARTs).
Chapter V: A Safety of navigation.
This chapter requires governments to ensure that all vessels are sufficiently and efficiently manned from a safety point of view. It places requirements on all vessels regarding voyage and passage planning, expecting a careful assessment of any proposed voyages by all who put to sea. Every mariner must take account of all potential dangers to navigation, weather forecasts, tidal predictions, the competence of the crew, and all other relevant factors. It also adds an obligation for all vessels’ masters to offer assistance to those in distress and controls the use of lifesaving signals with specific requirements regarding danger and distress messages.
