Query: What does a shipyard do?
Many studies have shown that painting is what generates almost half dangerous waste at a shipyard due to using high-pressure equipment to wash or remove any unwanted material that is on it like rust. Which will eventually make its way to the water and creates water pollution to the environment. Once these have compromised the surface of the hull the ship must go to the shipyard for maintenance. In a study in 2011 samples of sediments were collected from two sites in coastal marine area of Yongho Bay, one from the shipyard yard and the other 500m away. These results had analyzed that both samples contained metals that included Al, Fe, Li, V, Cr, Mn, Ni, Cu, Zn, As, Cd, Sn, and Pb. In addition, it had been confirmed that the concentration was higher in the first sample that was by the shipyard then the sample taking 500m away and was due to paint fragments applied to the steel ship hulls.
The Bangkok Dock Company (1957) Limited () is a Thai shipbuilding company. It operates as a state enterprise under the oversight of the Ministry of Defence. It was founded in 1865 as the Bangkok Dock Co by Captain John Bush, the harbour master of Bangkok, and was acquired by the Royal Thai Navy in 1957. The company now has two facilities: the original Bangkok dockyard on Charoen Krung Road next to Wat Yan Nawa, and a newer main facility operating at the Mahidol Adulyadej Naval Dockyard at Sattahip in Chonburi Province.
Steamship generally refers to larger steam-powered ships, usually ocean-going, capable of carrying a (ship's) boat. The engine room, to the right, is a concept drawing during the construction of the ship. The term steam wheeler is archaic and rarely used. In England, "steam packet", after its sailing predecessor, was the usual term; even "steam barge" could be used (Steam tonnage in Lloyd's Register exceeded sailing ships tonnage by 1865). The French transatlantic steamer was probably the last of her type to be equipped with sails, although she never used them. Steamships in turn were overtaken by diesel-driven ships in the second half of the 20th century. Most warships used steam propulsion from the 1860s until the late 20th century
Facilities at Giant's Grave improved, and included jetties to enable ships' ballast to be landed and dumped, rather than being thrown overboard. This latter approach had caused problems at Newport for the Monmouthshire and Brecon Canal, where ballast had been thrown into the river, and at Cardiff for the Glamorganshire Canal, where it had been thrown into the canal basin. Efforts were also made to improve the facilities at Neath. From 1818, a Harbour Board was established, and banks of copper slag, marked with buoys, were used to confine the channel. This enabled ships of over 300 tons to reach Neath quays on spring tides, although on neap tides Giant's Grave still had to be used. From 1824, when the connection to the Tennant Canal opened, much of the trade crossed the river and passed down the western bank to the port of Swansea.
The UK Chamber of Shipping is the trade body for shipping in the United Kingdom, representing over 140 shipping companies. They are one of the principle members of the International Chamber of Shipping. Their headquarters are in Park Street, London. The Chamber promotes British shipping around the world and often acts a source of marine knowledge to the media; for example in 2015 the Chamber worked with ITV in the production of a Maritime Nation Television Programme and in 2016 reported on various matters concerning the training of Merchant Navy Officers. The body is also responsible for working closely with the UK government and Maritime and Coastguard Agency; in 2014 the UK governments national Maritime Security strategy was unveiled at the Chamber. The official publisher of the UK Chamber of Shipping is Witherby Seamanship. The Merchant Navy Training Board is based at the UK Chamber's offices in London.
The Stone Fleet consisted of a fleet of aging ships (mostly whaleships) purchased in New Bedford and other New England ports, loaded with stone, and sailed south during the American Civil War by the Union Navy for use as blockships. They were to be deliberately sunk at the entrance of Charleston Harbor, South Carolina in the hope of obstructing blockade runners, then supplying Confederate interests. Although some sank along the way and others were sunk near Tybee Island, Georgia, to serve as breakwaters, wharves for the landing of Union troops, the majority were divided into two lesser fleets. One fleet was sunk to block the south channel off Morris Island, and the other to block the north channel near Rattlesnake Shoals off the present day Isle of Palms in what proved to be failed efforts to block access the main shipping channels into Charleston Harbor.
On 8 March 1885, the Spanish Navy authorized construction of the "Arsenal de Olongapo" and by the following September, work started at Olongapo. Both the harbor and its inner basin were dredged and a drainage canal was built, as the Spanish military authorities were planning to make Olongapo and their navy yard an "island." This canal also served as a line of defense and over which the bridge at the base's Main Gate passes. When the Arsenal was finished, the gunboats "Caviteño", "Santa Ana", and "San Quintín" were assigned for its defense. To complement these gunboats, coastal artilleries were planned for the east and west ends of the station, as well as on Grande Island.
Longships for the most part used two different kinds of anchors. The most common was a natural wood yoke formed from a tree branch. The weight was supplied by a stone passing laterally through the U of the yoke. The top of the yoke was closed by either a length of hardwood or a curved iron head, which kept the stone in place. One side of the head stuck out so it could dig into mud or sand. In the Ladby ship burial in Denmark, a unique iron anchor has been found, resembling the modern fisherman's anchor but without the crossbar. The cross bar may have rusted away. This anchor—made of Norwegian iron—has a long iron chain to which the hemp warp was attached. This construction has several advantages when anchored in deep waters or in rough seas.
SS "Ancon was an American cargo and passenger ship that became the first ship to officially transit the Panama Canal in 1914. The ship was built as Shawmut" for the Boston Steamship Company by the Maryland Steel Company, Sparrows Point, Maryland and put into Pacific service operating out of Puget Sound ports for Japan, China and the Philippine Islands. "Shawmut" and sister ship "Tremont" were two of the largest United States commercial ships in service at the time and the company eventually found them too expensive to operate.
The term "asbestos ware" refers to vessels containing 90% asbestos and 10% clay. Asbestos ware can resist heat up to 900–1000 °C. The clay made shaping of the vessel possible, but the high amount of asbestos does not classify it as pottery in a formal sense. It is believed that the asbestos ware was used in iron production such as spearheads, arrowheads and artefacts. The vessel is also drilled with many holes. The fact that the reduction of iron ore (FeO) with abundant carbon generates large amounts of carbon monoxide (CO) may suggest that the drilled holes were used to increase the influx of air (oxygen) required for proper glowing process. Iron ore is abundant in lakes e.g. in Finland.
Merchant ships held in reserve are managed as part of the separate National Defense Reserve Fleet within MARAD (US Maritime Administration). Several of its sites, such as at Suisun Bay in California, are also used to store regular Navy ships.
A steamship, often referred to as a steamer, is a type of steam powered vessel, typically ocean-faring and seaworthy, that is propelled by one or more steam engines that typically move (turn) propellers or paddlewheels. The first steamships came into practical usage during the early 1800s; however, there were exceptions that came before. Steamships usually use the prefix designations of "PS" for "paddle steamer" or "SS" for "screw steamer" (using a propeller or screw). As paddle steamers became less common, "SS" is assumed by many to stand for "steam ship". Ships powered by internal combustion engines use a prefix such as "MV" for "motor vessel", so it is not correct to use "SS" for most modern vessels.

In 1713 and 1714 a series of peace treaties ended the War of the Spanish Succession. As a result, thousands of seamen, including Britain's paramilitary privateers, were relieved of military duty, at a time when cross-Atlantic colonial shipping trade was beginning to boom. In addition, Europeans who had been pushed by unemployment to become sailors and soldiers involved in slaving were often enthusiastic to abandon that profession and turn to pirating, giving pirate captains a steady pool of recruits in west African waters and coasts.
In 1836 Westervelt built at least two ships under his own name, the "Baltimore" and "Mediator", in partnership with the 22-year-old ship chandler Marshall Owen Roberts as Westervelt & Roberts. Soon after Christian Bergh's retirement, Westervelt and Robert Carnley made an extensive tour of Europe, visiting the principal shipbuilding points, where Westervelt gathered information that he subsequently put to good use. Westervelt found an inactive life disagreeable and, after a year of travel, returned to the dry docks in 1838 and resumed shipbuilding.
Brunel showed his idea to John Scott Russell, an experienced naval architect and ship builder whom he had first met at the Great Exhibition. Scott Russell examined Brunel's plan and made his own calculations as to the ship's feasibility. He calculated that it would have a displacement of 20,000 tons and would require to achieve , but believed it was possible. At Scott Russell's suggestion, they approached the directors of the Eastern Steam Navigation Company.
In 1863 "Great Eastern" made three voyages to New York, with 2,700 passengers being carried out and 970 back to Britain along with a large tonnage of cargo. One of her paddle wheels was damaged on the last outward trip and she completed it using her screw, while on the return journey she ran down and damaged "Jane", a small sailing ship. The company lost nearly £20,000 on the voyages due to a price war between the Cunard and Inman shipping lines, and ended up with debts of more than £142,000, which forced them to lay up "Great Eastern".
Genoa, which forms the southern corner of the Milan-Turin-Genoa industrial triangle of Northwest Italy, is one of the country's major economic centers. The city has hosted massive shipyards and steelworks since the 19th century, and its solid financial sector dates back to the Middle Ages. The Bank of Saint George, founded in 1407, is among the oldest in the world and has played an important role in the city's prosperity since the middle of the 15th century. Today a number of leading Italian companies are based in the city, including Fincantieri, Selex ES, Ansaldo Energia, Ansaldo STS, Edoardo Raffinerie Garrone, Piaggio Aerospace, Mediterranean Shipping Company and Costa Cruises.
Between 1713 and 1714, a succession of peace treaties was signed which ended the War of the Spanish Succession. With the end of this conflict, thousands of seamen, including Britain's paramilitary privateers, were relieved of military duty. The result was a large number of trained, idle sailors at a time when the cross-Atlantic colonial shipping trade was beginning to boom. In addition, Europeans who had been pushed by unemployment to become sailors and soldiers involved in slaving were often enthusiastic to abandon that profession and turn to pirating, giving pirate captains for many years a constant pool of trained European recruits to be found in west African waters and coasts.
Modern commercial sea anchors are usually made of cloth, shaped like a parachute or cone, and rigged so that the wider end leads and the narrower end trails. When deployed, this type of sea anchor floats just under the surface, and the water moving past the sea anchor keeps it filled. Some varieties are cylindrical, with an adjustable opening in the rear that allows the amount of braking to be adjusted when deployed.
What is now the city of Bath was first settled by Europeans in mid-17th century, and was from an early date recognized as an ideal spot for shipbuilding. It is set on a stretch of the lower Kennebec River that was originally called Long Reach, because it could be sailed without changing the rigging. The town was incorporated as Bath in 1781, named after Bath, England. In the 19th century the city grew up on the west bank of the river, with the banks lined by shipyards. West of the river neighborhoods grew up north and south of a central business district, now located just north of United States Route 1. The neighborhood north of the downtown area is where some of it finest early residential architecture is to be found. The city's fortunes started to decline with the advent of steel ships, but the 1889 founding of the Bath Iron Works (now the city's only shipyard), and its success as a major shipbuilder for the United States Navy buoyed the local economy.
Russian President Dmitriy Medvedev stated in 2008 that Russia intended to build nuclear aircraft carriers in the next decade. However Russia currently does not have a yard capable of building aircraft carriers. All previous Soviet aircraft carriers were built in what was then known as the Nikolayev South Shipyard (Shipyard 444) at Nikolayev in what is now Ukraine. On August 2, 2010, Vladimir Vysotskiy stressed their importance: "If, for example, we do not have an aircraft carrier in the North, the combat capability of the Northern Fleet's guided-missile submarines will be reduced to zero after Day One because the submarines' principal adversary is aviation."

The Ŭnsan Line is an electrified standard-gauge freight-only secondary line of the Korean State Railway in South P'yŏngan Province, North Korea, running from Ŭnsan on the P'yŏngra Line to Taegŏn.
This enzyme belongs to the family of oxidoreductases, specifically those acting on paired donors, with O2 as oxidant and incorporation or reduction of oxygen. The oxygen incorporated need not be derived from O2 with 2-oxoglutarate as one donor, and incorporation of one atom o oxygen into each donor. The systematic name of this enzyme class is N6,N6,N6-trimethyl-L-lysine,2-oxoglutarate:oxygen oxidoreductase (3-hydroxylating). Other names in common use include trimethyllysine alpha-ketoglutarate dioxygenase, TML-alpha-ketoglutarate dioxygenase, TML hydroxylase, 6-N,6-N,6-N-trimethyl-L-lysine,2-oxoglutarate:oxygen oxidoreductase, and (3-hydroxylating). This enzyme participates in lysine degradation and L-carnitine biosynthesis and requires the presence of iron and ascorbate.
