Panamax
Panamax and New Panamax (or Neopanamax) are terms for the size limits for ships traveling through the Panama Canal. The limits and requirements are published by the Panama Canal Authority (ACP) in a publication titled "Vessel Requirements". These requirements also describe topics like exceptional dry seasonal limits, propulsion, communications, and detailed ship design. The allowable size is limited by the width and length of the available lock chambers, by the depth of water in the canal, and by the height of the Bridge of the Americas since that bridge's construction, along with the clearance under the Atlantic and Centennial Bridges since their constructions in 2019 and 2004 respectively. These dimensions give clear parameters for ships destined to traverse the Panama Canal and have influenced the design of cargo ships, naval vessels, and passenger ships. Panamax specifications have been in effect since the opening of the canal in 1914. In 2009, the ACP published the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panama Canal
The Panama Canal () is an artificial waterway in Panama that connects the Caribbean Sea with the Pacific Ocean. It cuts across the narrowest point of the Isthmus of Panama, and is a Channel (geography), conduit for maritime trade between the Atlantic and Pacific Oceans. Lock (water navigation), Locks at each end lift ships up to Gatun Lake, an artificial fresh water lake Above mean sea level, above sea level, created by damming the Chagres River and Lake Alajuela to reduce the amount of excavation work required for the canal. Locks then lower the ships at the other end. An average of of fresh water is used in a single passing of a ship. The canal is threatened by low water levels during droughts. The Panama Canal shortcut greatly reduces the time for ships to travel between the Atlantic and Pacific oceans, enabling them to avoid the lengthy, hazardous route around the southernmost tip of South America via the Drake Passage, the Strait of Magellan or the Beagle Channel. Its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panama Canal Expansion Project
The Panama Canal expansion project (), also called the Third Set of Locks Project, doubled the capacity of the Panama Canal by adding a new traffic lane, enabling more ships to transit the waterway, and increasing the width and depth of the lanes and locks, allowing larger ships to pass. The new ships, called New Panamax, are about one and a half times larger than the previous Panamax size and can carry over twice as much cargo. The expanded canal began commercial operation on 26 June 2016. The project has: * Built two new sets of locks, one each on the Atlantic and Pacific sides, and excavated new channels to the new locks * Widened and deepened existing channels * Raised the maximum operating water level of Gatun Lake''Proposal for the E ...

History Of The Panama Canal
In 1513 the Spanish conquistador Vasco Núñez de Balboa first crossed the Isthmus of Panama. When the narrow nature of the Isthmus became generally known, European powers noticed the possibility to dig a water passage between the Atlantic Ocean, Atlantic and Pacific Ocean, Pacific Oceans. A number of proposals for a ship canal across Central America were made between the sixteenth and nineteenth centuries. The chief rival to Panama was a History of the Nicaragua Canal, canal through Nicaragua. By the late nineteenth century, technological advances and commercial pressure allowed construction to begin in earnest. French entrepreneur Ferdinand de Lesseps led the initial attempt (1880–1889) to build a sea-level canal, as he had previously achieved in the building of the Suez Canal (1859–1869). A concession to build the canal was obtained from the Colombian government, at that time the possessor of the Panama Isthmus. The canal was only partly completed, as a result of the sev ...

Panama Canal Miraflores Locks
Panama, officially the Republic of Panama, is a country in Latin America at the southern end of Central America, bordering South America. It is bordered by Costa Rica to the west, Colombia to the southeast, the Caribbean Sea to the north, and the Pacific Ocean to the south. Its capital and largest city is Panama City, whose metropolitan area is home to nearly half of the country's over million inhabitants. Before the arrival of Spanish Empire, Spanish colonists in the 16th century, Panama was inhabited by a number of different Indigenous peoples of Panama, indigenous tribes. It Independence Act of Panama, broke away from Spain in 1821 and joined the Republic of Gran Colombia, a union of Viceroyalty of New Granada, Nueva Granada, Ecuador, and Venezuela. After Gran Colombia dissolved in 1831, Panama and Nueva Granada eventually became the Republic of Colombia. With the backing of the United States, Panama seceded from Colombia in 1903, allowing the construction of the Panama Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pedro Miguel Locks
The Panama Canal locks () are a lock system that lifts ships up to the main elevation of the Panama Canal and lowers them down again. The original canal had a total of six steps (three up, three down) for a ship's passage. The total length of the lock structures, including the approach walls, is over . The locks were one of the greatest engineering works ever to be undertaken when they opened in 1914. No other concrete construction of comparable size was undertaken until the Hoover Dam, in the 1930s. There are two independent transit lanes, since each lock is built double. The size of the original locks limits the maximum size of ships that can transit the canal; this size is known as Panamax. Construction on the Panama Canal expansion project, which included a third set of locks, began in September 2007, finished by May 2016 and began commercial operation on June 26, 2016. The new locks allow transit of larger, New Panamax ships, which have a greater cargo capacity than the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Draft (hull)
The draft or draught of a ship is a determined depth of the vessel below the waterline, measured vertically to its hull's lowest—its propellers, or keel, or other reference point. Draft varies according to the loaded condition of the ship. A deeper draft means the ship will have greater vertical depth below the waterline. Draft is used in under keel clearance calculations, where the draft is calculated with the available depth of water (from Electronic navigational charts) to ensure the ship can navigate safely, without grounding. Navigators can determine their draught by calculation or by visual observation (of the ship's painted load lines). Related terminology A ship's draft/draught is the "depth of the vessel below the waterline measured vertically to the lowest part of the hull, propellers, or other reference point". That is, the draft or draught is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if de ...

Balboa, Panama
Balboa is a district of Panama City, located at the Pacific entrance to the Panama Canal. It was the capital of the Panama Canal Zone under American administration. History The town of Balboa, founded by the United States during the construction of the Panama Canal, was named after Vasco Núñez de Balboa, the Spanish conquistador credited with discovering the Pacific Ocean. The name was suggested to the Panama Canal Zone authorities by the Peruvian ambassador to Panama. The hilly area north of Panama City was home to a few subsistence ranches and unused marshlands prior to being drained, filled, and leveled by the United States Army Corps of Engineers. The town of Balboa, like most towns in the Canal Zone, was served by the Canal Zone Government–operated schools, post office, police and fire stations, commissary, cafeteria, movie theater, service center, bowling alley, other recreational facilities and company stores. There were several schools in the area, including Balb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ore-bulk-oil Carrier
An ore-bulk-oil carrier, also known as combination carrier or OBO, is a ship designed to be capable of carrying wet or dry cargoes. The idea is to reduce the number of empty (ballast) voyages, in which large ships only carry a cargo one way and return empty for another. These are a feature of the larger bulk trades (e.g. crude oil from the Middle East, iron ore and coal from Australia, South Africa and Brazil). The Russian word for "ore-bulk-oil carrier", ''nefterudovoz'' (нефтерудовоз, literally "oil/ore carrier"), in combination with a number, is often used as a proper name for a ship, e.g. ''Nefterudovoz-51M''. History The idea of the OBO was that it would function as a tanker when the tanker markets were good and a bulk/ore carrier when those markets were good. It would also be able to take "wet" cargo (oil) one way and "dry" cargo (bulk cargoes or ore) the other way, thus reducing the time it had to sail in ballast (i.e. empty). The first OBO carrier was the ''N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Referendum
A referendum, plebiscite, or ballot measure is a Direct democracy, direct vote by the Constituency, electorate (rather than their Representative democracy, representatives) on a proposal, law, or political issue. A referendum may be either binding (resulting in the adoption of a new policy) or advisory (functioning like a large-scale opinion poll). Etymology 'Referendum' is the gerundive form of the Latin language, Latin verb , literally "to carry back" (from the verb , "to bear, bring, carry" plus the inseparable prefix , here meaning "back"Marchant & Charles, Cassell's Latin Dictionary, 1928, p. 469.). As a gerundive is an adjective,A gerundive is a verbal adjective (Kennedy's Shorter Latin Primer, 1962 edition, p. 91.) not a noun, it cannot be used alone in Latin, and must be contained within a context attached to a noun such as , "A proposal which must be carried back to the people". The addition of the verb (3rd person singular, ) to a gerundive, denotes the idea of nece ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
