TEMPSC (Totally Enclosed Motor Propelled Survival Craft) are mandatory on all merchant vessels, tankers, MODUs, Floating Offshore Oil and Gas Platforms and some fixed offshore oil and gas platforms per 1983 Chapter III amendment to IMO SOLAS 1974. When USS Indianapolis, a cruiser operating alone, was sunk on 30 July 1945, none of its larger lifeboats were launched, and the survivors had to rely on balsa liferafts automatically released as the ship sank many of the crew perished, but the balsa liferafts saved others ultimately 316 of 1,196 crew survived. These liferafts were intended only for use during a short term before lifeboats or another ship in the convoy or group could bring them aboard. They were inexpensive, and during the war thousands were stored in any space possible on US warships and merchant ships. These balsa liferafts were designed to hold five to ten men on a platform suspended on the inside or fifteen to twenty-five hanging lines placed on the outsides. In 1943 the US developed a balsa wood liferaft that would not sink, irrespective of the number of holes (from enemy fire) in it. The new type lifeboat could be driven either by a small motor or sail. The space in between was designed to help persons in the water be pulled aboard, and could be enclosed with a canvas top. They had two enclosed cabins (one at each end) which could hold a total of 25 persons. These radically new lifeboats were 24 feet (7.3 m) in length and weighed 5,000 lb (2,300 kg).

The result was the first enclosed, unsinkable, self-righting lifeboat, manufactured in Delanco, New Jersey the first units were delivered in 1944. The US Navy asked various groups and manufacturers to suggest solutions. ĭuring World War II and the Battle of the Atlantic with convoys going to northern Russia through the Arctic Ocean it was found that the chance of the crews of merchant ships surviving in open lifeboats was not very good unless they were rescued in a couple of hours. This was resolved by the wider use of collapsible lifeboats, a number of which had been carried on Titanic. The need for so many more lifeboats on the decks of passenger ships after 1912 led to the use of most of the deck space available even on the large ships, creating the problem of restricted passageways. Modern lifeboats carry an Emergency Position-Indicating Radio Beacon (EPIRB) and either a radar reflector or Search and Rescue Transponder (SART).Ī collapsible Engelhardt lifeboat carrying survivors of the sunken RMS Titanic

The International Convention for the Safety of Life at Sea (SOLAS) and the International Life-Saving Appliance Code (LSA) requires certain emergency equipment be carried on each lifeboat and liferaft used on international voyages. Some lifeboats are more capably equipped to permit self-rescue, with supplies such as a radio, an engine and sail, heater, navigational equipment, solar water stills, rainwater catchments and fishing equipment. Lifeboats have oars, flares and mirrors for signaling, first aid supplies, and food and water for several days. The cover serves as protection from sun, wind and rain, can be used to collect rainwater, and is normally made of a reflective or fluorescent material that is highly visible. Ship-launched lifeboats are lowered from davits on a ship's deck, and are hard to sink in normal circumstances. Commercial aircraft are also required to carry auto-inflating liferafts in case of an emergency water landing offshore oil platforms also have liferafts.

A quick release and pressure release mechanism is fitted on ships so that the canister or pump automatically inflates the lifeboat, and the lifeboat breaks free of the sinking vessel.

Inflatable lifeboats may be equipped with auto-inflation ( carbon dioxide or nitrogen) canisters or mechanical pumps. Recreational sailors usually carry inflatable liferafts, though a few prefer small proactive lifeboats that are harder to sink and can be sailed to safety. The ship's tenders of cruise ships often double as lifeboats. In the military, a lifeboat may double as a whaleboat, dinghy, or gig. Lifeboat drills are required by law on larger commercial ships. Costa Concordia, shortly after capsizing with lifeboats at shoreĪ lifeboat or liferaft is a small, rigid or inflatable boat carried for emergency evacuation in the event of a disaster aboard a ship.
