Air-sea rescue (ASR or A/SR, also known as sea-air rescue), and aeronautical and maritime search and rescue (AMSAR) by the ICAO and IMO, is the coordinated search and rescue (SAR) of the survivors of emergency water landings as well as people who have survived the loss of their seagoing vessel. ASR can involve a wide variety of resources including seaplanes, helicopters, submarines, rescue boats and ships. Specialized equipment and techniques have been developed. Both military and civilian units can perform air-sea rescue. Its principles are laid out in the International Aeronautical and Maritime Search and Rescue Manual. The International Convention on Maritime Search and Rescue is the legal framework that applies to international air-sea rescue.

Air-sea rescue operations carried out during times of conflict have been credited with saving valuable trained and experienced airmen. Moreover, the knowledge that such operations are being carried out greatly enhanced the morale of the combat aircrew faced not only with the expected hostile reaction of the enemy but with the possible danger of aircraft malfunction during long overwater flights. As such, many militaries have opted to develop a capable air-sea rescue component, and ensure that such assets are available during most deployments. Early air-sea rescue operations were performed by flying boats or floatplanes, with the first dedicated unit operating such aircraft being established near the final months of World War I. While initially restricted to in-shore operations and with limited equipment, capabilities and resources would be expanded over the following decades. By the start of World War II, various nations were operating capable air-sea rescue units that operated a combination of amphibious and land-based fixed wing aircraft.

The International Convention for the Safety of Life at Sea (SOLAS) is an international maritime treaty which sets out minimum safety standards in the construction, equipment and operation of merchant ships. The International Maritime Organization convention requires signatory flag states to ensure that ships flagged by them comply with at least these standards.

Initially prompted by the sinking of the Titanic, the current version of SOLAS is the 1974 version, known as SOLAS 1974, which came into force on 25 May 1980, and has been amended several times. As of April 2022, SOLAS 1974 has 167 contracting states, which flag about 99% of merchant ships around the world in terms of gross tonnage.

The United Kingdom is a founding member of the United Nations and one of five permanent members of the UN Security Council.

As the fifth largest provider of financial contributions to the United Nations, the UK provided 5 percent of the UN budget in 2015, and 6.7 percent of the peacekeeping budget. British English is one of the six official languages of the United Nations, and the United Kingdom is home to the International Maritime Organization, whose head office is in London.

The International Regulations for Preventing Collisions at Sea 1972, also known as Collision Regulations (COLREG), are published by the International Maritime Organization (IMO) and set out, among other things, the "rules of the road" or navigation rules to be followed by ships and other vessels at sea to prevent collisions between two or more vessels. COLREG can also refer to the specific political line that divides inland waterways, which are subject to their own navigation rules, and coastal waterways which are subject to international navigation rules. They are derived from a multilateral treaty called the Convention on the International Regulations for Preventing Collisions at Sea, also known as Collision Regulations of 1960.

Although rules for navigating vessels inland may differ, the international rules specify that they should be as closely in line with the international rules as possible. In most of continental Europe, the Code Européen des Voies de la Navigation Intérieure (CEVNI, or the European Code for Navigation on Inland Waters) apply. In the United States, the rules for vessels navigating inland are published alongside the international rules.

International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW) sets minimum qualification standards for masters, officers and watch personnel on seagoing merchant ships and large yachts. STCW was adopted in 1978 by the International Maritime Organization (IMO) conference in London, and entered into force in 1984. The convention was significantly amended in 1995 and 2010, and entered into force on 1 January 2012.

The 1978 STCW Convention Caruso was the first to establish minimum basic requirements on training, certification and watchkeeping for seafarers on an international level. Previously the minimum standards of training, certification and watchkeeping of officers and ratings were established by individual governments, usually without reference to practices in other countries. As a result, minimum standards and procedures varied widely, even though shipping is extremely international by nature.

Lambeth (/ˈlæmbəθ/) is a district in South London, England, which today also gives its name to the (much larger) London Borough of Lambeth. Lambeth itself was an ancient parish in the county of Surrey. It is situated 1 mile (1.6 km) south of Charing Cross, across the river from Westminster Palace. The population of the London Borough of Lambeth was 303,086 in 2011. The area experienced some slight growth in the medieval period as part of the manor of Lambeth Palace. By the Victorian era, the area had seen significant development as London expanded, with dense industrial, commercial and residential buildings located adjacent to one another. By this point, there were distinct localities (like Vauxhall) appearing on the map, and a separate parish of South Lambeth was created in 1861.

The changes brought by World War II altered much of the fabric of Lambeth. Subsequent development in the late 20th and early 21st centuries has seen an increase in the number of high-rise buildings. The area is home to the International Maritime Organization. Lambeth is home to one of the largest Portuguese-speaking communities in the UK, and Portuguese is the second most commonly spoken language in Lambeth after English.

In sailing and boating, a vessel's freeboardis the distance from the waterline to the upper deck level, measured at the lowest point of sheer where water can enter the boat or ship. In commercial vessels, the latter criterion measured relative to the ship's load line, regardless of deck arrangements, is the mandated and regulated meaning.

In yachts, a low freeboard is often found on racing boats, for increased speed (by reducing weight and therefore drag). A higher freeboard will give more room in the cabin, but will increase weight and drag, compromising speed. A higher freeboard, such as used on ocean liners, also helps weather waves and so reduce the likelihood of being washed over by full water waves. A low-freeboard vessel is susceptible to taking in water in rough seas. Freighter ships and warships use high freeboard designs to increase internal volume, which also allows them to satisfy International Maritime Organization (IMO) damage stability regulations, due to increased reserve buoyancy.

A gas carrier, gas tanker, LPG carrier, or LPG tanker is a ship designed to transport LPG, LNG, CNG, or liquefied chemical gases in bulk. Gases are kept refrigerated onboard the ships to enable safe carriage in liquid and vapour form and for this reason, gas carriers usually have onboard refrigeration systems. Design and construction of all gas carriers operating internationally is regulated by the International Maritime Organization through the International Code of the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk. There are various types of gas carriers, depending on the type of gas carried and the type of containment system, two of the most common being the Moss Type B (spherical) type and the membrane (typically GTT) type.

The International Convention on Maritime Search and Rescue (SAR Convention) is a maritime safety convention of the International Maritime Organization. It entered into force on 22 June 1985. The convention forms part of the legal framework covering search and rescue at sea.

The SAR Convention was adopted on 27 April 1979. It entered into force on 22 June 1985.
