Federal Shipbuilding
The Federal Shipbuilding and Drydock Company was a United States shipyard, active from 1917 to 1948. It was founded during World War I to build ships for the United States Shipping Board. During World War II, it built ships as part of the U.S. Government's Emergency Shipbuilding program. Operated by a subsidiary of the United States Steel Corporation, the shipyard was located at Kearny Point where the mouth of the Hackensack River meets Newark Bay in the Port of New York and New Jersey. The shipyard site is now part of River Terminal, a massive distribution facility that is partially a foreign trade zone. Federal built numerous destroyers, destroyer escorts and a handful of light cruisers as well as merchant ships during and between the wars. Around 570 vessels were contracted for construction by Federal SB&DD Company with about 100 not delivered fully completed due to the end of the World War II. Federal also had a yard at Port Newark during World War II that built destroyers and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shipbuilding
Shipbuilding is the construction of ships and other floating vessels. It normally takes place in a specialized facility known as a shipyard. Shipbuilders, also called shipwrights, follow a specialized occupation that traces its roots to before recorded history. Shipbuilding and ship repairs, both commercial and military, are referred to as "naval engineering". The construction of boats is a similar activity called boat building. The dismantling of ships is called ship breaking. History Pre-history The earliest known depictions (including paintings and models) of shallow-water sailing boats is from the 6th to 5th millennium BC of the Ubaid period of Mesopotamia. They were made from bundled reeds coated in bitumen and had bipod masts. They sailed in shallow coastal waters of the Persian Gulf. 4th millennium BC Ancient Egypt Evidence from Ancient Egypt shows that the early Egyptians knew how to assemble planks of wood into a ship hull as early as 3100 BC.

Great Depression
The Great Depression (19291939) was an economic shock that impacted most countries across the world. It was a period of economic depression that became evident after a major fall in stock prices in the United States. The economic contagion began around September and led to the Wall Street stock market crash of October 24 (Black Thursday). It was the longest, deepest, and most widespread depression of the 20th century. Between 1929 and 1932, worldwide gross domestic product (GDP) fell by an estimated 15%. By comparison, worldwide GDP fell by less than 1% from 2008 to 2009 during the Great Recession. Some economies started to recover by the mid-1930s. However, in many countries, the negative effects of the Great Depression lasted until the beginning of World War II. Devastating effects were seen in both rich and poor countries with falling personal income, prices, tax revenues, and profits. International trade fell by more than 50%, unemployment in the U.S. rose to 23% and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interwar Period
In the history of the 20th century, the interwar period lasted from 11 November 1918 to 1 September 1939 (20 years, 9 months, 21 days), the end of the World War I, First World War to the beginning of the World War II, Second World War. The interwar period was relatively short, yet featured many significant social, political, and economic changes throughout the world. Petroleum-based energy production and associated mechanisation led to the prosperous Roaring Twenties, a time of both social mobility and economic mobility for the middle class. Automobiles, electric lighting, radio, and more became common among populations in the developed world. The indulgences of the era subsequently were followed by the Great Depression, an unprecedented worldwide economic downturn that severely damaged many of the world's largest economies. Politically, the era coincided with the rise of communism, starting in Russia with the October Revolution and Russian Civil War, at the end of World War I ...

Ontario
Ontario ( ; ) is one of the thirteen provinces and territories of Canada.Ontario is located in the geographic eastern half of Canada, but it has historically and politically been considered to be part of Central Canada. Located in Central Canada, it is Canada's most populous province, with 38.3 percent of the country's population, and is the second-largest province by total area (after Quebec). Ontario is Canada's fourth-largest jurisdiction in total area when the territories of the Northwest Territories and Nunavut are included. It is home to the nation's capital city, Ottawa, and the nation's most populous city, Toronto, which is Ontario's provincial capital. Ontario is bordered by the province of Manitoba to the west, Hudson Bay and James Bay to the north, and Quebec to the east and northeast, and to the south by the U.S. states of (from west to east) Minnesota, Michigan, Ohio, Pennsylvania, and New York. Almost all of Ontario's border with the United States f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montreal
Montreal ( ; officially Montréal, ) is the List of the largest municipalities in Canada by population, second-most populous city in Canada and List of towns in Quebec, most populous city in the Provinces and territories of Canada, Canadian province of Quebec. Founded in 1642 as ''Fort Ville-Marie, Ville-Marie'', or "City of Mary", it is named after Mount Royal, the triple-peaked hill around which the early city of Ville-Marie is built. The city is centred on the Island of Montreal, which obtained its name from the same origin as the city, and a few much smaller peripheral islands, the largest of which is Île Bizard. The city is east of the national capital Ottawa, and southwest of the provincial capital, Quebec City. As of 2021, the city had a population of 1,762,949, and a Census Metropolitan Area#Census metropolitan areas, metropolitan population of 4,291,732, making it the List of the largest municipalities in Canada by population, second-largest city, and List of cen ...

Fireboat
A fireboat or fire-float is a specialized watercraft with pumps and nozzles designed for fighting shoreline and shipboard fires. The first fireboats, dating to the late 18th century, were tugboats, retrofitted with firefighting equipment. Older designs derived from tugboats and modern fireboats more closely resembling seafaring ships can both be found in service today. Some departments would give their multi-purpose craft the title of "fireboat" also. They are frequently used for fighting fires on docks and shore side warehouses as they can directly attack fires in the supporting underpinnings of these structures. They also have an effectively unlimited supply of water available, pumping directly from below the hull. Fireboats can be used to assist shore-based firefighters when other water is in low supply or is unavailable, for example, due to earthquake breakage of water mains, as happened in San Francisco due to the 1989 Loma Prieta earthquake. Some modern firebo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jib Crane
A crane is a type of machine, generally equipped with a hoist (device), hoist rope, wire ropes or chains, and Sheave (mechanical), sheaves, that can be used both to lift and lower materials and to move them horizontally. It is mainly used for lifting heavy objects and transporting them to other places. The device uses one or more simple machines to create mechanical advantage and thus move loads beyond the normal capability of a human. Cranes are commonly employed in transportation for the loading and unloading of freight, in construction for the movement of materials, and in manufacturing for the assembling of heavy equipment. The first known crane machine was the shaduf, a water-lifting device that was invented in ancient Mesopotamia (modern Iraq) and then appeared in ancient Egyptian technology. Construction cranes later appeared in ancient Greece, where they were powered by men or animals (such as donkeys), and used for the construction of buildings. Larger cranes were later ...

Funnel (ship)
A funnel is the smokestack or chimney on a ship used to expel boiler steam and smoke or engine exhaust. They are also commonly referred to as stacks. Purpose The primary purpose of a ship's funnel(s) is to lift the exhaust gases clear of the deck, in order not to foul the ship's structure or decks, and to avoid impairing the ability of the crew to carry out their duties. In steam ships the funnels also served to help induce a convection draught through the boilers. Design Since the introduction of steam-power to ships in the 19th century, the funnel has been a distinctive feature of the silhouette of a vessel, and used for recognition purposes. Funnel area The required funnel cross-sectional area is determined by the volume of exhaust gases produced by the propulsion plant. Often this area is too great for a single funnel. Early steam vessels needed multiple funnels ( had 5 when launched), but as efficiency increased new machinery needed fewer funnels. Merchant ships ...

Scotch Marine Boiler
A "Scotch" marine boiler (or simply Scotch boiler) is a design of steam boiler best known for its use on ships. The general layout is that of a squat horizontal cylinder. One or more large cylindrical furnaces are in the lower part of the boiler shell. Above this are many small-diameter fire-tubes. Gases and smoke from the furnace pass to the back of the boiler, then return through the small tubes and up and out of the chimney. The ends of these multiple tubes are capped by a smokebox, outside the boiler shell. The Scotch boiler is a fire-tube boiler, in that hot flue gases pass through tubes set within a tank of water. As such, it is a descendant of the earlier Lancashire boiler, and like the Lancashire it uses multiple separate furnaces to give greater heating area for a given furnace capacity. It differs from the Lancashire in two respects: many small-diameter tubes (typically diameter each) are used to increase the ratio of heating area to cross-section. Secondly, the over ...

Emergency Fleet Corporation
The Emergency Fleet Corporation (EFC) was established by the United States Shipping Board, sometimes referred to as the War Shipping Board, on 16 April 1917 pursuant to the Shipping Act (39 Stat. 729) to acquire, maintain, and operate merchant ships to meet national defense, foreign and domestic commerce during World War I. The Shipping Board had been established while the United States was at peace, with the intent to restore the nation's Merchant Marine. That changed with war. In the words of Edward N. Hurley, Chairman of the Board: When the United States declared war against Germany the whole purpose and policy of the Shipping Board and the Fleet Corporation suffered a radical change overnight. From a body established to restore the American Merchant Marine to its old glory, the Shipping Board was transformed into a military agency to bridge the ocean with ships and to maintain the line of communication between America and Europe. Conceived as an instrumentality of peace, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slipway
A slipway, also known as boat ramp or launch or boat deployer, is a ramp on the shore by which ships or boats can be moved to and from the water. They are used for building and repairing ships and boats, and for launching and retrieving small boats on trailers towed by automobiles and flying boats on their undercarriage. The nautical terms ways and skids are alternative names for slipway. A ship undergoing construction in a shipyard is said to be ''on the ways''. If a ship is scrapped there, she is said to be ''broken up in the ways''. As the word "slip" implies, the ships or boats are moved over the ramp, by way of crane or fork lift. Prior to the move the vessel's hull is coated with grease, which then allows the ship or boat to "slip" off of the ramp and progress safely into the water. Slipways are used to launch (newly built) large ships, but can only dry-dock or repair smaller ships. Pulling large ships against the greased ramp would require too much force. Therefor ...
