Russian Coast Defense Ship Gangut (1888)
''Gangut'' ( Russian: броненосец "Гангут") was an Imperial Russian coast defense ship named after the Battle of Gangut. This ship was a scaled-down version of the s. Design and construction The ship was designed as a smaller version of the on the instruction of Navy Minister Ivan Shestakov. The aim was to have a cheaper vessel able to operate in the shallow water of the Baltic Sea with long range deployment to the Mediterranean and the Far East. The specification was issued in 1887 and the design was approved by the Marine Technical Committee in 1888. She was built by New Admiralty yard, Saint Petersburg. Construction started on 29 October 1888, and she was launched on 3 July 1893. Completed in 1894, she was 600 tons over her designed displacement which led to an increase in draught and a loss in speed. Her trials were difficult and she had to return to Kronstadt to have repairs after 19 days. Several modernisation schemes to correct the defects were c ...

Battle Of Gangut
The Battle of Gangut (russian: Гангутское сражение, fi, Riilahden taistelu, Finland Swedish: ''Slaget vid Rilax'', sv, Sjöslaget vid Hangöudd) took place on 27 July Jul./ 7 August 1714 Greg. during the Great Northern War (1700–1721), in the waters of Riilahti Bay, north of the Hanko Peninsula, near the site of the modern-day city of Hanko, Finland, between the Swedish Navy and Imperial Russian Navy. It was the first important victory of the Russian fleet in its history. Name of the battle The word ''Gangut'' in the name of the battle is a romanization of ''Гангут'', which is the traditional Russian cyrillization of ''Hangöudd'', the traditional Swedish name of the Hanko Peninsula. Seldom used names are ''Battle of Hangö''Great Soviet Encyclopedia, Third edition, English translation, Volume 6 (1975), page 527, Battle of Hangö (Finnish ''Hanko'') and ''Battle of Hangöudd'' (Finnish ''Hankoniemi'').

Barbette
Barbettes are several types of gun emplacement in terrestrial fortifications or on naval ships. In recent naval usage, a barbette is a protective circular armour support for a heavy gun turret. This evolved from earlier forms of gun protection that eventually led to the pre-dreadnought. The name ''barbette'' ultimately comes from fortification - it originally meant a raised platform or mound, as in the French phrase ''en barbette'', which refers to the practice of firing a cannon over a parapet rather than through an embrasure in a fortification's casemate. The former gives better angles of fire but less protection than the latter. The disappearing gun was a variation on the barbette gun; it consisted of a heavy gun on a carriage that would retract behind a parapet or into a gunpit for reloading. Barbettes were primarily used in coastal defences, but saw some use in a handful of warships, and some inland fortifications. The term is also used for certain aircraft gun mounts. Sh ...

Underwater Diving
Underwater diving, as a human activity, is the practice of descending below the water's surface to interact with the environment. It is also often referred to as diving, an ambiguous term with several possible meanings, depending on context. Immersion in water and exposure to high ambient pressure have physiological effects that limit the depths and duration possible in ambient pressure diving. Humans are not physiologically and anatomically well-adapted to the environmental conditions of diving, and various equipment has been developed to extend the depth and duration of human dives, and allow different types of work to be done. In ambient pressure diving, the diver is directly exposed to the pressure of the surrounding water. The ambient pressure diver may dive on breath-hold (freediving) or use breathing apparatus for scuba diving or surface-supplied diving, and the saturation diving technique reduces the risk of decompression sickness (DCS) after long-duration deep dives ...

Imperial Russian Navy
The Imperial Russian Navy () operated as the navy of the Russian Tsardom and later the Russian Empire from 1696 to 1917. Formally established in 1696, it lasted until dissolved in the wake of the February Revolution of 1917. It developed from a smaller force that had existed prior to Tsar Peter the Great's founding of the modern Russian navy during the Second Azov campaign in 1696. It expanded in the second half of the 18th century and reached its peak strength by the early part of the 19th century, behind only the British and French fleets in terms of size. The Imperial Navy drew its officers from the aristocracy of the Empire, who belonged to the state Russian Orthodox Church. Young aristocrats began to be trained for leadership at a national naval school. From 1818 on, only officers of the Imperial Russian Navy were appointed to the position of Chief Manager of the Russian-American Company, based in Russian America (present-day Alaska) for colonization and fur-trade developme ...

Bulkhead (partition)
A bulkhead is an upright wall within the hull of a ship or within the fuselage of an airplane. Other kinds of partition elements within a ship are decks and deckheads. Etymology The word ''bulki'' meant "cargo" in Old Norse. During the 15th century sailors and builders in Europe realized that walls within a vessel would prevent cargo from shifting during passage. In shipbuilding, any vertical panel was called a head. So walls installed abeam (side-to-side) in a vessel's hull were called "bulkheads". Now, the term bulkhead applies to every vertical panel aboard a ship, except for the hull itself. History Bulkhead partitions are considered to have been a feature of Chinese junks, a type of ship. Song Dynasty author Zhu Yu (fl. 12th century) wrote in his book of 1119 that the hulls of Chinese ships had a bulkhead build. The 5th-century book ''Garden of Strange Things'' by Liu Jingshu mentioned that a ship could allow water to enter the bottom without sinking. Archaeolo ...

Boiler Room (ship)
On a ship, the fire room, or FR or boiler room or stokehold, referred to the space, or spaces, of a vessel where water was brought to a boil. The steam was then transmitted to a separate engine room, often (but not always) located immediately aft, where it was utilized to power the vessel. To increase the safety and damage survivability of a vessel, the machinery necessary for operations may be segregated into various spaces, the fire room was one of these spaces, and was among the largest physical compartment of the machinery space. On some ships, the space comprised more than one fire room, such as forward and aft, or port or starboard fire rooms, or may be simply numbered. Each room was connected to a flue, exhausting into a stack ventilating smoke. By their nature, fire rooms were less complex than their allied engine room and were normally supervised by less senior personnel. On a large percentage of vessels, ships and boats, the fire room was located near the bottom, and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Of Finland
The Gulf of Finland ( fi, Suomenlahti; et, Soome laht; rus, Фи́нский зали́в, r=Finskiy zaliv, p=ˈfʲinskʲɪj zɐˈlʲif; sv, Finska viken) is the easternmost arm of the Baltic Sea. It extends between Finland to the north and Estonia to the south, to Saint Petersburg in Russia to the east, where the river Neva drains into it. Other major cities around the gulf include Helsinki and Tallinn. The eastern parts of the Gulf of Finland belong to Russia, and some of Russia's most important oil harbors are located farthest in, near Saint Petersburg (including Primorsk). As the seaway to Saint Petersburg, the Gulf of Finland has been and continues to be of considerable strategic importance to Russia. Some of the environmental problems affecting the Baltic Sea are at their most pronounced in the shallow gulf. Proposals for a tunnel through the gulf have been made. Geography The gulf has an area of . The length (from the Hanko Peninsula to Saint Petersburg) is and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vyborg
Vyborg (; rus, Вы́борг, links=1, r=Výborg, p=ˈvɨbərk; fi, Viipuri ; sv, Viborg ; german: Wiborg ) is a town in, and the administrative center of, Vyborgsky District in Leningrad Oblast, Russia. It lies on the Karelian Isthmus near the head of the Vyborg Bay, to the northwest of St. Petersburg, east of the Finnish capital Helsinki, and south of Russia's border with Finland, where the Saimaa Canal enters the Gulf of Finland. The population of Vyborg is as follows: Located in the boundary zone between the East Slavic/Russian and Finnish worlds, formerly well known as one of the few medieval towns in Finland, Vyborg has changed hands several times in history, most recently in 1944 when the Soviet Union captured it from Finland during World War II. Finland evacuated the entire population of the city and resettled them within the rest of the country. On March 25, 2010, Dmitry Medvedev named Vyborg the "City of Military Glory".

Harvey Armour
Harvey armor was a type of steel naval armor developed in the early 1890s in which the front surfaces of the plates were case hardened. The method for doing this was known as the Harvey process, and was invented by the American engineer Hayward Augustus Harvey. This type of armor was used in the construction of capital ships until superseded by Krupp armor in the late 1890s. The Harvey United Steel Company was a steel cartel whose chairman was Albert Vickers. The year 1894 would see the ten main producers of armor plate, including Vickers, Armstrong, Krupp, Schneider, Carnegie and Bethlehem Steel, form the Harvey Syndicate. Predecessors Before the appearance of compound armor in the 1880s, armor plating was made from uniform homogeneous iron or steel plates backed by several inches of teak to absorb the shock of projectile impact. Compound armor appeared in the mid-1880s and was made from two different types of steel, a very hard but brittle high-carbon steel front ...

Waterline
The waterline is the line where the hull of a ship meets the surface of the water. Specifically, it is also the name of a special marking, also known as an international load line, Plimsoll line and water line (positioned amidships), that indicates the draft of the ship and the legal limit to which a ship may be loaded for specific water types and temperatures in order to safely maintain buoyancy, particularly with regard to the hazard of waves that may arise. Varying water temperatures will affect a ship's draft, because warm water is less dense than cold water, providing less buoyancy. In the same way, fresh water is less dense than salinated or seawater with a similar lessening effect upon buoyancy. For vessels with displacement hulls, the hull speed is defined by, among other things, the waterline length. In a sailing boat, the waterline length can change significantly as the boat heels, and can dynamically affect the speed of the boat. A waterline can also refer to any l ...
