Priz-class Deep-submergence Rescue Vehicles
The Priz class (Project 1855) is a type of deep-submergence rescue vehicle (DSRV) operated by the government of Russia. There are known to be at least five vessels of the class, several of which were involved in the failed rescue attempt when the submarine sank on 12 August 2000. The Russian word "Priz" (“приз”) means "prize". Specifications The titanium- hulled vessels are long, wide and high, with a displacement of . Capable of operating at depths up to , they have a range of , at a top speed of . With a crew of four, they can stay submerged for up to 120 hours, but with the crew and a full complement of 20 passengers aboard this is reduced to 10 hours. The Priz vessels are equipped with manipulators that can lift up to . According to a report on Russian television (Vesti, on Rossiya channel, 7 August 2005), the Project 1855 Priz vessel was designed by the Lazurit Design Bureau of Nizhny Novgorod, and four modifications were made: ''AS-26'' (1986), ''AS-28'' (19 ...

Deep Submergence Rescue Vehicle
A deep-submergence rescue vehicle (DSRV) is a type of deep-submergence vehicle used for rescue of personnel from disabled submarines and submersibles. While DSRV is the term most often used by the United States Navy, other nations have different designations for their equivalent vehicles. List of deep submergence rescue vehicles Australia ASRV ''Remora'' was the Australian navy's DSRV. It is based on a diving bell design. China The People's Republic of China has three Type 925 Dajiang class and three Type 926 class. Each ship is equipped with either two Type 7103 DSRV or one LR7 crewed submersible undersea rescue vehicle. Europe France, Norway and the UK share the NATO Submarine Rescue System programme. Italy Italy operates , equipped with the SRV-300 submersible in a submarine rescue role * The SRV-300, built by Drass-Galeazzi, was delivered in 1999 and can operate up to depth, hosting 12 persons in the rescue compartment. The submarine, modified as deployable in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Titanium
Titanium is a chemical element; it has symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in sea water, aqua regia, and chlorine. Titanium was discovered in Cornwall, Great Britain, by William Gregor in 1791 and was named by Martin Heinrich Klaproth after the Titans of Greek mythology. The element occurs within a number of minerals, principally rutile and ilmenite, which are widely distributed in the Earth's crust and lithosphere; it is found in almost all living things, as well as bodies of water, rocks, and soils. The metal is extracted from its principal mineral ores by the Kroll and Hunter processes. The most common compound, titanium dioxide (TiO2), is a popular photocatalyst and is used in the manufacture of white pigments. Other compounds include titanium tetrachloride (TiCl4), a component of smoke screens and cata ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submarine Hull
A submarine hull has two major components, the ''superstructure'' and the ''pressure hull''. The external portion of a submarine’s hull—that part that does not resist sea pressure and is free-flooding—is known as the “superstructure” in American submarine terminology and the “casing” in British submarine terminology. It is sometimes also referred to as the “light hull” or other descriptive terms. The superstructure (''casing'' in British usage) of a submarine is the outer non-watertight, “free-flooding” hull which provides a hydrodynamically efficient shape. The pressure hull is the inner hull of a submarine that resists sea pressure and maintains the submarine’s structural integrity at (operating) depth. Shapes Modern submarines are usually cigar-shaped. This design, already visible on very early submarines, is called a " teardrop hull". It is structurally efficient for withstanding external pressure, and significantly reduces the hydrodynamic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p. 5. This is accomplished by means of its "draft marks". A merchant vessel has t ...

Electric Battery
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. When a battery is supplying power, its positive Terminal (electronics), terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the source of electrons. When a battery is connected to an external electric load, those negatively charged electrons flow through the circuit and reach the positive terminal, thus causing a redox reaction by attracting positively charged ions, or cations. Thus, higher energy reactants are converted to lower energy products, and the Gibbs free energy, free-energy difference is delivered to the external circuit as electrical energy. Historically the term "battery" specifically referred to a device composed of multiple cells; however, the usage has evolved to include devices composed of a single cell. Primary battery, Primary (single-use or "disposable") batter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The list of ships of Russia by project number includes all Soviet and Russian ships by known assigned project numbers. Ship descriptions are Russian assigned classifications when known. The Russian term ''проект'' ( tr. ''proyekt'') can be translated either as the cognate "project" or as "design".
