Post-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 Miraflores Locks
Panama, officially the Republic of Panama, is a country in Latin America at the southern end of Central America, bordering South America.

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] |
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 ...

Civil Engineer
A civil engineer is a person who practices civil engineering – the application of planning, designing, constructing, maintaining, and operating infrastructure while protecting the public and environmental health, as well as improving existing infrastructure that may have been neglected. Civil engineering is one of the oldest engineering disciplines because it deals with constructed environment including planning, designing, and overseeing construction and maintenance of building structures, and facilities, such as roads, railroads, airports, bridges, harbors, channels, dams, irrigation projects, pipelines, power plants, and water and sewage systems. The term "civil engineer" was established by John Smeaton in 1750 to contrast engineers working on civil projects with the military engineers, who worked on armaments and defenses. Over time, various sub-disciplines of civil engineering have become recognized and much of military engineering has been absorbed by civil engineering. ...

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).

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".

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 ...

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] |
Tonne
The tonne ( or ; symbol: t) is a unit of mass equal to 1,000 kilograms. It is a non-SI unit accepted for use with SI. It is also referred to as a metric ton in the United States to distinguish it from the non-metric units of the short ton ( United States customary units) and the long ton ( British imperial units). It is equivalent to approximately 2,204.6 pounds, 1.102 short tons, and 0.984 long tons. The official SI unit is the megagram (Mg), a less common way to express the same amount. Symbol and abbreviations The BIPM symbol for the tonne is t, adopted at the same time as the unit in 1879.Table 6 . BIPM. Retrieved on 2011-07-10. Its use is also official for the metric ton in the United States, having been adopted by the United States |
Deadweight Tonnage
Deadweight tonnage (also known as deadweight; abbreviated to DWT, D.W.T., d.w.t., or dwt) or tons deadweight (DWT) is a measure of how much weight a ship can carry. It is the sum of the weights of cargo, fuel, fresh water Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salt (chemistry), salts and other total dissolved solids. The term excludes seawater and brackish water, but it does include ..., ballast water, provisions, passengers, and crew. DWT is often used to specify a ship's maximum permissible deadweight (i.e. when it is fully loaded so that its Plimsoll line is at water level), although it may also denote the actual DWT of a ship not loaded to capacity. Definition Deadweight tonnage is a measure of a vessel's weight carrying capacity, not including the empty weight of the ship. It is distinct from the displacement (weight of water displaced), which includes the ship's own weight, or the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
