Port Of Marín And Ria De Pontevedra
The port of Marín and Ria de Pontevedra is located in the municipalities of Marín and Pontevedra, Galicia (Spain). It is on the southern shore of the Ria de Pontevedra. The port stretches from Punta Pesqueira in the municipality of Marín to Placeres in the municipality of Pontevedra. It is used as a merchant port (containers, bulk) and Fishing port. It is also used as a marina. History Port activity has been documented in Pontevedra and its ria since Antiquity, thanks to the Roman milestone, which is preserved in the Pontevedra Museum and whose inscription refers to its importance as a maritime communication route. In the 16th century, Pontevedra was the most important city in Galicia and the port of Pontevedra was the busiest in the region and in northwest Spain. Some historians estimate that the economic movement generated by the settlement could reach 80,000 Ducats per year. In the 17th century, the port of Pontevedra began to decline due to the lack of depth ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marín, Pontevedra
Marín is a town and municipality in Galicia, Spain in the province of Pontevedra. This town is where the Spanish Navy was settled. It was established as the Escuela Naval Militar de Oficiales (Naval Academy for Officers). It is located on the southern shore of the estuary of Pontevedra, in the comarca of O Morrazo. Formerly named San Xiao Ancorados by ships anchored nearby, but it is a popular distortion of "Encoirados," meaning leather tanneries, as they were in the Lameira river which flows into the urban center of the village. Father Sarmiento says his name comes from the Latin word ''mare'', meaning sea, but it is now known to be derived from the name of a former possessor of this land named Marinus. Marín derives from Marini, "property of Marinus." Both references to the sea are, therefore, pure coincidences.

Steelmaking
Steelmaking is the process of producing steel from iron ore and carbon/or scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (the most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel. Limiting dissolved gases such as nitrogen and oxygen and entrained impurities (termed "inclusions") in the steel is also important to ensure the quality of the products cast from the liquid steel. Steelmaking has existed for millennia, but it was not commercialized on a massive scale until the mid-19th century. An ancient process of steelmaking was the crucible process. In the 1850s and 1860s, the Bessemer process and the Siemens-Martin process turned steelmaking into a heavy industry. Today there are two major commercial processes for making steel, namely basic oxygen steelmaking, which has liquid pig-iron from the b ...

Pulp (paper)
Pulp is a lignocellulosic fibrous material prepared by chemically or mechanically separating cellulose fibers from wood, fiber crops, waste paper, or rags. Mixed with water and other chemical or plant-based additives, pulp is the major raw material used in papermaking and the industrial production of other paper products. History Before the widely acknowledged invention of papermaking by Cai Lun in China around 105 AD, paper-like writing materials such as papyrus and amate were produced by ancient civilizations using plant materials which were largely unprocessed. Strips of bark or bast material were woven together, beaten into rough sheets, dried, and polished by hand. Pulp used in modern and traditional papermaking is distinguished by the process which produces a finer, more regular slurry of cellulose fibers which are pulled out of solution by a screen and dried to form sheets or rolls. The earliest paper produced in China consisted of bast fibers from the paper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jetty
A jetty is a structure that projects from land out into water. A jetty may serve as a breakwater, as a walkway, or both; or, in pairs, as a means of constricting a channel. The term derives from the French word ', "thrown", signifying something thrown out. For regulating rivers Another form of jetties, wing dams are extended out, opposite one another, ''from each bank of a river'', at intervals, to contract a wide channel, and by concentration of the current to produce a deepening. At the outlet of tideless rivers Jetties have been constructed on each side of the outlet river of some of the rivers flowing into the Baltic, with the objective of prolonging the scour of the river and protecting the channel from being shoaled by the littoral drift along the shore. Another application of parallel jetties is in lowering the bar in front of one of the mouths of a deltaic river flowing into a tide — a virtual prolongation of its less sea, by extending the scour of the ...

Inclined Plane
An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle from the vertical direction, with one end higher than the other, used as an aid for raising or lowering a load. The inclined plane is one of the six classical simple machines defined by Renaissance scientists. Inclined planes are used to move heavy loads over vertical obstacles. Examples vary from a ramp used to load goods into a truck, to a person walking up a pedestrian ramp, to an automobile or railroad train climbing a grade. Moving an object up an inclined plane requires less force than lifting it straight up, at a cost of an increase in the distance moved. The mechanical advantage of an inclined plane, the factor by which the force is reduced, is equal to the ratio of the length of the sloped surface to the height it spans. Owing to conservation of energy, the same amount of mechanical energy (work) is required to lift a given object by a given vertical distance, disregarding losse ...

Shore
A shore or a shoreline is the fringe of land at the edge of a large body of water, such as an ocean, sea, or lake. In physical oceanography, a shore is the wider fringe that is geologically modified by the action of the body of water past and present, while the beach is at the edge of the shore, representing the intertidal zone where there is one. In contrast to a coast, a shore can border any body of water, while the coast must border an ocean or a sea. Therefore, in that sense, a coast is a type of shore. However, the word "coast" often refers to an area far wider than the shore, often stretching miles into the interior. Shores are influenced by the topography of the surrounding landscape, as well as by water induced erosion, such as waves. The geological composition of rock and soil dictates the type of shore which is created. Rivieras ''Riviera'' is an Italian word for "shoreline", ultimately derived from Latin ''ripa'' ("riverbank"). It came to be applied as a proper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Container Ship
A container ship (also called boxship or spelled containership) is a cargo ship that carries all of its load in truck-size intermodal containers, in a technique called containerization. Container ships are a common means of commercial intermodal freight transport and now carry most seagoing non-bulk cargo. Container ship capacity is measured in twenty-foot equivalent units (TEU). Typical loads are a mix of 20-foot (1-TEU) and 40-foot (2-TEU) ISO-standard containers, with the latter predominant. Today, about 90% of non-bulk cargo worldwide is transported by container ships, and the largest modern container ships can carry up to 24,000 TEU (e.g., '' Ever Ace''). Container ships now rival crude oil tankers and bulk carriers as the largest commercial seaborne vessels. History There are two main types of dry cargo: bulk cargo and break bulk cargo. Bulk cargoes, like grain or coal, are transported unpackaged in the hull of the ship, generally in large volume. Break-bulk ...

Bulk Cargo
Bulk cargo is commodity cargo that is transported unpackaged in large quantities. Description Bulk cargo refers to material in either liquid or granular, particulate form, as a mass of relatively small solids, such as petroleum/ crude oil, grain, coal, or gravel. This cargo is usually dropped or poured, with a spout or shovel bucket, into a bulk carrier ship's hold, railroad car/ railway wagon, or tanker truck/ trailer/semi-trailer body. Smaller quantities can be boxed (or drummed) and palletised; cargo packaged in this manner is referred to as breakbulk cargo. Bulk cargo is classified as liquid or dry. The Baltic Exchange is based in London and provides a range of indices benchmarking the cost of moving bulk commodities, dry and wet, along popular routes around the seas. Some of these indices are also used to settle Freight Futures, known as FFA's. The most famous of the Baltic indices is the Baltic Dry Indices, commonly called the BDI. This is a derived funct ...

Maintenance (technical)
The technical meaning of maintenance involves functional checks, servicing, repairing or replacing of necessary devices, equipment, machinery, building infrastructure, and supporting utilities in industrial, business, and residential installations. Over time, this has come to include multiple wordings that describe various cost-effective practices to keep equipment operational; these activities occur either before or after a failure. Definitions Maintenance functions can defined as maintenance, repair and overhaul (MRO), and MRO is also used for maintenance, repair and operations. Over time, the terminology of maintenance and MRO has begun to become standardized. The United States Department of Defense uses the following definitions: Federal Standard 1037C and from MIL-STD-188 and from the Department of Defense Dictionary of Military and Associated Terms * Any activity—such as tests, measurements, replacements, adjustments, and repairs—intended to retain or restore a ...

Break Bulk Cargo
In shipping, break-bulk, breakbulk, or break bulk cargo, also called general cargo, refers to goods that are stowed on board ship in individually counted units. Traditionally, the large numbers of items are recorded on distinct bills of lading that list them by different commodities. This is in contrast to cargo stowed in modern intermodal containers as well as bulk cargo, which goes directly, unpackaged and in large quantities, into a ship's hold(s), measured by volume or weight (for instance, oil or grain). The term ''break-bulk'' derives from the phrase breaking bulk, a term for unloading part of a ship’s cargo, or commencing unloading the cargo. Ships carrying break-bulk cargo are often called general cargo ships. Break-bulk/general cargo consists of goods transported, stowed and handled piecemeal to some degree, typically bundled somehow in unit loads for hoisting, either with cargo nets, slings, or crates, or stacked on trays, pallets or skids. Furthermore, ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shipyard
A shipyard, also called a dockyard or boatyard, is a place where ships are built and repaired. These can be yachts, military vessels, cruise liners or other cargo or passenger ships. Dockyards are sometimes more associated with maintenance and basing activities than shipyards, which are sometimes associated more with initial construction. The terms are routinely used interchangeably, in part because the evolution of dockyards and shipyards has often caused them to change or merge roles. Countries with large shipbuilding industries include Australia, Brazil, China, Croatia, Denmark, Finland, France, Germany, India, Ireland, Italy, Japan, the Netherlands, Norway, the Philippines, Poland, Romania, Russia, Singapore, South Korea, Sweden, Taiwan, Turkey, the United Arab Emirates, Ukraine, the United Kingdom, the United States and Vietnam. The shipbuilding industry is more fragmented in Europe than in Asia where countries tend to have fewer, larger companies. Many naval vessels ar ...
