Deep-submergence vehicle

A deep-sea submarine (English Deep Submergence Vehicle DSV ) is a submarine which can be different from the mass of the usually military submarines withstand the high pressure of the deep sea. Deep-sea submarines are mainly used for scientific purposes, but there are Deep Submergence Rescue Vehicle with the rescue or submarines that can withstand deep depths greater than 800 meters.

The history of deep-sea submarines begins with the bathysphere of Charles William Beebe, the nearly 1000 feet deep appeared in Bermuda 1934. All other deep-sea vehicles are also based on spherical pressure vessels since, in contrast to Beebe's pioneering achievement, however, modern submarines can move under its own power.

A special form of deep-sea submarine represents the bathyscaphe, which is merely a pressure hulls with a container for ballast and buoyancy gasoline in principle and only limited moves. With the bathyscaphe Trieste a record dive trip to 10,916 feet ( Challenger Deep ) was made on 23 January 1960.

Manned deep-sea submarines dive to depths up to 6,000 meters. One of the most famous submarines of this type is Alvin ( dive depth of 4,500 meters, from 2011: 6,500 meters), with which in 1986 the well-known dive to the wreck of the Titanic was undertaken. Also very well known are the two Russian submarines of the type I ( depth 6,000 meters). Next, the French submarine are Nautile ( 6,000 meters) and the Japanese Shinkai 6500 (within 6,527 feet ) in active service. The Chinese Jiaolong can reach depths of up to 7000 meters. With 7,062 meters of the 5,188 meter national record was surpassed by July 2011 in June 2012.

On March 26, 2012 James Cameron reached his boat Deepsea Challenger alone, as the third man in a total depth of 10,898 meters, the bottom of the Challengertiefs in the Mariana Trench, the deepest point of the putative oceans.
