USS Canonicus (ID-1696)
The second USS ''Canonicus'' was the Southern Pacific freighter ''El Cid'' temporarily converted for planting the World War I North Sea Mine Barrage. Newport News Shipbuilding and Dry Dock Company launched ''El Cid'' at Newport News, Virginia on 7 October 1899 for service between New York City and Gulf of Mexico seaports of New Orleans and Galveston, Texas. The United States Shipping Board took control of the ship from Southern Pacific Steamship Company in 1917. She was fitted out for United States Navy service by Morse Dry Dock and Repair Company at Brooklyn, New York. Work began on 22 November 1917. Gun platforms were added for two anti-aircraft guns forward and a 5"/51 caliber gun aft. The minelaying conversion enabled her to carry mines on three decks, and included six Otis elevators individually capable of transferring two mines every 20 seconds from the storage decks to the launching deck. Stern ports were cut for launching the mines and the rudder quadrant was rai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

North Sea Mine Barrage
The North Sea Mine Barrage, also known as the Northern Barrage, was a large minefield laid easterly from the Orkney Islands to Norway by the United States Navy (assisted by the Royal Navy) during World War I. The objective was to inhibit the movement of U-boats from bases in Germany to the Atlantic shipping lanes bringing supplies to the British Isles. Rear Admiral Lewis Clinton-Baker, commanding the Royal Navy minelaying force at the time, described the barrage as the "biggest mine planting stunt in the world's history."Belknap, Reginald Rowan ''The Yankee mining squadron; or, Laying the North Sea mining barrage'' (1920) United States Naval Institute pp.5,15,18-22,27-36,43-47,56,82-83,101&108 Larger fields with greater numbers of mines were laid during World War II. Concept The idea of a mine barrage across the North Sea was first proposed in the summer of 1916 by Admiral Reginald Bacon and was agreed at the Allied Naval Conference on 5 September 1917.

Ship Commissioning
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before she is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify any deficiencies needing corre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watertight Subdivision
A compartment is a portion of the space within a ship defined vertically between decks and horizontally between bulkheads. It is analogous to a room within a building, and may provide watertight subdivision of the ship's hull important in retaining buoyancy if the hull is damaged. Subdivision of a ship's hull into watertight compartments is called compartmentation. History Bulkhead watertight compartments were originally invented by the Chinese. These compartments strengthened the junks and slowed flooding in case of holing during the Han and Song dynasties. The wide application of Chinese watertight compartments soon spread to the Europeans through the Indian and Arab merchants. The economics of early unsinkable passenger ships was scrutinized in an 1882 Scientific American article. Watertight subdivision Watertight subdivision limits loss of buoyancy and freeboard in the event of damage, and may protect vital machinery from flooding. Most ships have some pumping capacit ...

Elevator
An elevator or lift is a wire rope, cable-assisted, hydraulic cylinder-assisted, or roller-track assisted machine that vertically transports people or freight between floors, levels, or deck (building), decks of a building, watercraft, vessel, or other structure. They are typically powered by electric motors that drive traction cables and counterweight systems such as a hoist (device), hoist, although some pump hydraulic fluid to raise a cylindrical piston like a hydraulic jack, jack. In agriculture and manufacturing, an elevator is any type of conveyor device used to lift materials in a continuous stream into bins or silos. Several types exist, such as the chain and bucket elevator, grain auger screw conveyor using the principle of Archimedes' screw, or the chain and paddles or forks of hay elevators. Languages other than English, such as Japanese, may refer to elevators by loanwords based on either ''elevator'' or ''lift''. Due to wheelchair access laws, elevators are ...

Otis Elevator Company
Otis Worldwide Corporation (trade name, branded as the Otis Elevator Company, its former legal name) is an American company that develops, manufactures and markets elevators, escalators, moving walkways, and related equipment. Based in Farmington, Connecticut, U.S, Otis is the world's largest manufacturer of vertical transportation systems, principally focusing on elevators, moving walkways, and escalators. The company pioneered the development of the "safety elevator", invented by Elisha Otis in 1852, which used a special mechanism to lock the elevator car in place should the hoisting ropes fail. The Otis Elevator Company was acquired by United Technologies in 1976, but it was spun off as an independent company 44 years later in April 2020 as Otis Worldwide Corporation. Its slogan is "Made to move you". History The booming elevator market In 1852, Elisha Otis invented the safety elevator, which automatically comes to a halt if the hoisting rope breaks. After a demonstra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Mines
A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel or a particular vessel type, akin to anti-infantry vs. anti-vehicle mines. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered. Although international law requires signatory nations to declare mined areas, precise locations remain secret; and non-complying individual ...

Minelayer
A minelayer is any warship, submarine or military aircraft deploying explosive mines. Since World War I the term "minelayer" refers specifically to a naval ship used for deploying naval mines. "Mine planting" was the term for installing controlled mines at predetermined positions in connection with coastal fortifications or harbor approaches that would be detonated by shore control when a ship was fixed as being within the mine's effective range. Before World War I, mine ships were termed mine planters generally. For example, in an address to the United States Navy ships of Mine Squadron One at Portland, England, Admiral Sims used the term “mine layer” while the introduction speaks of the men assembled from the “mine planters”. During and after that war the term "mine planter" became particularly associated with defensive coastal fortifications. The term "minelayer" was applied to vessels deploying both defensive- and offensive mine barrages and large scale sea mining. " ...

Morse Dry Dock And Repair Company
The Morse Dry Dock and Repair Company was a major late 19th/early 20th century ship repair and conversion facility located in New York City. Begun in the 1880s as a small shipsmithing business known as the Morse Iron Works, the company grew to be one of America's largest ship repair and refit facilities, at one time owning the world's largest floating dry dock. In addition to servicing some of the finest steamships of the era, the company maintained many of the yachts of New York's elite business community, and also occasionally built small watercraft such as tugboats. During World War I, the company was heavily engaged in work for the U.S. government and military. In 1929, the company merged with five other major New York ship repair facilities to become United Dry Docks, Inc.—the largest company of its type in the world—with the former head of Morse Dry Dock, Edward P. Morse, as chairman of the board. United Dry Docks later changed its name to United Shipyards, I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
