DeLong Pier
A DeLong pier is a type of elonged ersatz pier constructed from prefabricated barge-like sections and simple Caisson (engineering), caissons driven into a harbor's seafloor. First used during the Vietnam War at Cam Ranh Bay, the DeLong pier was originally designed shortly after the Second World War by the DeLong Corporation, and a prototype was constructed not long after in Charleston, South Carolina for use by the Transportation Corps in 1952. This prototype would, in late 1965, be the first of four DeLong piers installed in the bay by the 497th Port Engineer Company. To install the pier, component barges carrying tubular caissons and Jack (device), jacks are towed along with a crane-bearing barge directly from the manufacturing or storage site to the target location. The barges are then placed in position near shore, where the crane-bearing barge then unloads the caissons and threads them through the wells of the component barges. The crane then operates a pile driver on each cai ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Port Lane DeLong Pier, November 1968
A port is a maritime facility comprising one or more wharves or loading areas, where ships load and discharge cargo and passengers. Although usually situated on a sea coast or estuary, ports can also be found far inland, such as Hamburg, Manchester and Duluth; these access the sea via rivers or canals. Because of their roles as ports of entry for immigrants as well as soldiers in wartime, many port cities have experienced dramatic multi-ethnic and multicultural changes throughout their histories. Ports are extremely important to the global economy; 70% of global merchandise trade by value passes through a port. For this reason, ports are also often densely populated settlements that provide the labor for processing and handling goods and related services for the ports. Today by far the greatest growth in port development is in Asia, the continent with some of the world's largest and busiest ports, such as Singapore and the Chinese ports of Shanghai and Ningbo-Zhou ...

Ersatz
An ersatz good () is a substitute good, especially one that is considered inferior to the good it replaces. It has particular connotations of wartime usage. Etymology ''Ersatz'' is a German word literally meaning ''substitute'' or ''replacement''. Although it is used as an adjective in English, it is a noun in German. In German orthography noun phrases formed are usually represented as a single word, forming compound nouns such as ''Ersatzteile'' ("spare parts") or ''Ersatzspieler'' ("substitute player"). While ''ersatz'' in English generally means that the substitution is of unsatisfactory or inferior quality compared with the "real thing", in German, there is no such implication: e.g., ''Ersatzteile'' 'spare parts' is a technical expression without any implication about quality, whereas ''Kaffeeersatz'' ' coffee substitute' is not made from coffee beans, and is thus inferior. The term for inferior substitute in German would be ''Surrogat'', which is cognate to English word "sur ...

Pier
Seaside pleasure pier in England.html" ;"title="Brighton, England">Brighton, England. The first seaside piers were built in England in the early 19th century. A pier is a raised structure that rises above a body of water and usually juts out from its shore, typically supported by piling, piles or column, pillars, and provides above-water access to offshore areas. Frequent pier uses include fishing, [oat docking and access for both passengers and cargo, and oceanside recreation. Bridges, buildings, and walkways may all be supported by architectural piers. Their open structure allows tides and currents to flow relatively unhindered, whereas the more solid foundations of a quay or the closely spaced piles of a wharf can act as a breakwater, and are consequently more liable to silting. Piers can range in size and complexity from a simple lightweight wooden structure to major structures extended over . In American English, a pier may be synonymous with a dock. Piers have been b ...

Caisson (engineering)
In geotechnical engineering, a caisson ( or ; borrowed from French ''caisson'', from Italian ''cassone'', meaning ''large box'', an augmentative of ''cassa'') is a watertight retaining structure used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, or for the repair of ships. Caissons are constructed in such a way that the water can be pumped out, keeping the work environment dry. When piers are being built using an open caisson, and it is not practical to reach suitable soil, friction pilings may be driven to form a suitable sub-foundation. These piles are connected by a foundation pad upon which the column pier is erected. Caisson engineering has been used at least since the 18th century, and was notably used in the construction of the Brooklyn Bridge, which was completed in 1883. Types To install a caisson in place, it is brought down through soft mud until a suitable foundation material is encountered. While bedrock is pr ...

Seafloor
The seabed (also known as the seafloor, sea floor, ocean floor, and ocean bottom) is the bottom of the ocean. All floors of the ocean are known as 'seabeds'. The structure of the seabed of the global ocean is governed by plate tectonics. Most of the ocean is very deep, where the seabed is known as the abyssal plain. Seafloor spreading creates mid-ocean ridges along the center line of major ocean basins, where the seabed is slightly shallower than the surrounding abyssal plain. From the abyssal plain, the seabed slopes upward toward the continents and becomes, in order from deep to shallow, the continental rise, slope, and shelf. The depth within the seabed itself, such as the depth down through a sediment core, is known as the “depth below seafloor.” The ecological environment of the seabed and the deepest waters are collectively known, as a habitat for creatures, as the “benthos.” Most of the seabed throughout the world's oceans is covered in layers of marine sediments ...

Vietnam War
The Vietnam War (also known by #Names, other names) was a conflict in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and was officially fought between North Vietnam and South Vietnam. The north was supported by the Soviet Union, China, and other communist states, while the south was United States in the Vietnam War, supported by the United States and other anti-communism, anti-communist Free World Military Forces, allies. The war is widely considered to be a Cold War-era proxy war. It lasted almost 20 years, with direct U.S. involvement ending in 1973. The conflict also spilled over into neighboring states, exacerbating the Laotian Civil War and the Cambodian Civil War, which ended with all three countries becoming communist states by 1975. After the French 1954 Geneva Conference, military withdrawal from Indochina in 1954 – following their defeat in the First Indochina War – the Viet Minh to ...

Cam Ranh Bay
Cam Ranh Bay ( vi, Vịnh Cam Ranh) is a deep-water bay in Vietnam in Khánh Hòa Province. It is located at an inlet of the South China Sea situated on the southeastern coast of Vietnam, between Phan Rang and Nha Trang, approximately 290 kilometers (180 miles) northeast of Ho Chi Minh City (formerly Saigon). Cam Ranh is considered the finest deepwater shelter in Southeast Asia. The continental shelf of Southeast Asia is relatively narrow at Cam Ranh Bay, bringing deep water close to land. Since 2011-2014, Vietnamese authorities have hired Russian consultants and purchased Russian technologies to re-open Cam Ranh Bay (a former United States and later Soviet military base) as the site of a new naval maintenance and logistics facility for foreign warships. Overview Historically, the bay has been significant from a military standpoint. The French used it as a naval base for their forces in Indochina. It was also used as a staging area for the 40-ship Imperial Russian flee ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the World War II by country, vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies of World War II, Allies and the Axis powers. World War II was a total war that directly involved more than 100 million Military personnel, personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources.

Barge
Barge nowadays generally refers to a flat-bottomed inland waterway vessel which does not have its own means of mechanical propulsion. The first modern barges were pulled by tugs, but nowadays most are pushed by pusher boats, or other vessels. The term barge has a rich history, and therefore there are many other types of barges. History of the barge Etymology "Barge" is attested from 1300, from Old French ''barge'', from Vulgar Latin ''barga''. The word originally could refer to any small boat; the modern meaning arose around 1480. ''Bark'' "small ship" is attested from 1420, from Old French ''barque'', from Vulgar Latin ''barca'' (400 AD). The more precise meaning of Barque as "three-masted sailing vessel" arose in the 17th century, and often takes the French spelling for disambiguation. Both are probably derived from the Latin ''barica'', from Greek ''baris'' "Egyptian boat", from Coptic ''bari'' "small boat", hieroglyphic Egyptian D58-G29-M17-M17-D21-P1 and similar ' ...
