PD-50
''PD-50'' (russian: ПД-50), Soviet designation Project 7454, was a Russian large floating dry dock built at the Götaverken Arendal shipyard in Gothenburg, Sweden and commissioned in the 1980s. At the time, it was the world's largest floating dry dock and used primarily to service the ships and submarines of the Northern Fleet. The long and wide floating dock was owned by Shipyard No. 82 and stationed at Roslyakovo, near Murmansk. In November 2018, the dock sank after a power outage while holding the aircraft carrier/ aircraft cruiser . History In March 1978, Götaverken Arendal shipyard in Gothenburg, Sweden was awarded a contract for the construction of the world's largest floating dry dock for the Soviet Union. While the company had previously built mainly oil tankers and bulk carriers, it was struggling for new orders after demand for one of its main products had dwindled following the 1973 oil crisis, and bidding for the dry dock was one of the shipyard's attem ...

Dry Dock
A dry dock (sometimes drydock or dry-dock) is a narrow basin or vessel that can be flooded to allow a load to be floated in, then drained to allow that load to come to rest on a dry platform. Dry docks are used for the construction, maintenance, and repair of ships, boats, and other watercraft. History Greco-Roman world The Greek author Athenaeus of Naucratis (V 204c-d) reports something that may have been a dry dock in Ptolemaic Egypt in the reign of Ptolemy IV Philopator (221-204 BC) on the occasion of the launch of the enormous ''Tessarakonteres'' rowing ship. It has been calculated that a dock for a vessel of such a size might have had a volume of 750,000 gallons of water. In Roman times, a shipyard at Narni, which is still studied, may have served as a dry dock. Medieval China The use of dry docks in China goes at least as far back the 10th century A.D. In 1088, Song Dynasty scientist and statesman Shen Kuo (1031–1095) wrote in his '' Dream Pool Essays'': Renais ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bulk Carrier
A bulk carrier or bulker is a merchant ship specially designed to transport unpackaged bulk cargo — such as grains, coal, ore, steel coils, and cement — in its cargo holds. Since the first specialized bulk carrier was built in 1852, economic forces have led to continued development of these ships, resulting in increased size and sophistication. Today's bulk carriers are specially designed to maximize capacity, safety, efficiency, and durability. Today, bulk carriers make up 21 percent of the world's merchant fleets, and they range in size from single-hold mini-bulk carriers to mammoth ore ships able to carry 400,000 metric tons of deadweight (DWT). A number of specialized designs exist: some can unload their own cargo, some depend on port facilities for unloading, and some even package the cargo as it is loaded. Over half of all bulk carriers have Greek, Japanese, or Chinese owners, and more than a quarter are registered in Panama. South Korea is the largest single bu ...

Soviet Border Troops
The Soviet Border Troops (russian: Пограничные войска СССР, Pogranichnyye voyska SSSR) were the border guard of the Soviet Union, subordinated to the Soviet state security agency: first to the ''Cheka''/State Political Directorate, OGPU, then to NKVD/Ministry for State Security (USSR), MGB and, finally, to the KGB. Accordingly, they were known as NKVD Border Security and KGB Border Troops. Unlike the border guards of many other countries, Soviet Border Troops also included the sea, maritime border guarding units, and aviation units (i.e., a coast guard). The mission of the Border Troops included repulsing armed incursions into Soviet territory; preventing illegal crossings of the border or the transport of weapons, explosives, contraband or subversive literature across the border; monitoring the observance of established procedures at border crossing points; monitoring the observance by Soviet and foreign ships of navigation procedures in Soviet territoria ...

Norway–Russia Border
The border between Norway and Russia ( no, Russergrensen / Russergrensa, russian: Российско-норвежская граница, ''Rossiysko-Norvezhskaya Granitsa'') consists of a land border between Sør-Varanger, Norway, and Pechengsky District, Russia, and a marine border in the Varangerfjord. It further consists of a border between the two countries' exclusive economic zones (EEZ) in the Barents Sea and the Arctic Ocean. Between 1944 and 1991 the border was between Norway and the Soviet Union. There is a single border crossing, on E105, located at Storskog in Norway and Borisoglebsky (Boris Gleb) in Russia. The Norwegian side is patrolled by the Garrison of Sør-Varanger and is under the jurisdiction of the Norwegian Border Commissioner, while the Russian side is patrolled by the Border Guard Service of Russia. Two-thirds of the border follows two rivers, the Pasvikelva and Jakobselva. The border was defined as a march in a treaty in 1326 and separated wh ...

Coastline Of Norway
The coastline of Norway is formed along the Skagerrak, North Sea, Norwegian Sea, and Barents Sea. This considers only the mainland coastline and excludes Svalbard. A straight line along Norway's sea borders (the coastal perimeter) is long. Along the coast there are many fjords, islands, and bays, resulting in a low-resolution coastline of over . At linear intercepts, this length increases to (see the coastline paradox). Much of Norway's wealth is linked to its long coastline; for example, the petroleum industry, maritime transport, fishing, and fish farming. The Norwegian landscape was formed by glaciers that eroded the basement rock and formed countless valleys and fjords, as well as the characteristic skerries that protect the land from the ocean along most of the mainland coastline. There are only a few shorter or longer stretches where the mainland is exposed to the open sea along the coast: at Lindesnes, Lista, Jæren, Stad, Hustadvika, and Folda in Trøndelag, and al ...

Tugboat
A tugboat or tug is a marine vessel that manoeuvres other vessels by pushing or pulling them, with direct contact or a tow line. These boats typically tug ships in circumstances where they cannot or should not move under their own power, such as in crowded harbour or narrow canals, or cannot move at all, such as barges, disabled ships, log rafts, or oil platforms. Some are ocean-going, some are icebreakers or salvage tugs. Early models were powered by steam engines, long ago superseded by diesel engines. Many have deluge gun water jets, which help in firefighting, especially in harbours. Types Seagoing Seagoing tugs (deep-sea tugs or ocean tugboats) fall into four basic categories: #The standard seagoing tug with model bow that tows almost exclusively by way of a wire cable. In some rare cases, such as some USN fleet tugs, a synthetic rope hawser may be used for the tow in the belief that the line can be pulled aboard a disabled ship by the crew owing to its lightness ...

Ballast Water
Ballast is used in ships to provide moment to resist the lateral forces on the hull. Insufficiently ballasted boats tend to tip or heel excessively in high winds. Too much heel may result in the vessel capsizing. If a sailing vessel needs to voyage without cargo, then ballast of little or no value will be loaded to keep the vessel upright. Some or all of this ballast will then be discarded when cargo is loaded. Uses Ballast takes many forms. The simplest form of ballast used in small day sailers is so-called "live ballast", or the weight of the crew. By sitting on the windward side of the hull, the heeling moment must lift the weight of the crew. On more advanced racing boats, a wire harness called a trapeze is used to allow the crew to hang completely over the side of the hull without falling out; this provides much larger amounts of righting moment due to the larger leverage of the crew's weight, but can be dangerous if the wind suddenly dies, as the sudden loss of heeling ...

Pelagic Zone
The pelagic zone consists of the water column of the open ocean, and can be further divided into regions by depth (as illustrated on the right). The word ''pelagic'' is derived . The pelagic zone can be thought of as an imaginary cylinder or water column between the surface of the sea and the bottom. Conditions in the water column change with depth: pressure increases; temperature and light decrease; salinity, oxygen, micronutrients (such as iron, magnesium and calcium) all change. Marine life is affected by bathymetry (underwater topography) such as the seafloor, shoreline, or a submarine seamount, as well as by proximity to the boundary between the ocean and the atmosphere at the ocean surface, which brings light for photosynthesis, predation from above, and wind stirring up waves and setting currents in motion. The pelagic zone refers to the open, free waters away from the shore, where marine life can swim freely in any direction unhindered by topographical constraints. Th ...
