Jackscrew
A jackscrew, or screw jack, is a type of jack that is operated by turning a leadscrew. It is commonly used to lift moderately and heavy weights, such as vehicles; to raise and lower the horizontal stabilizers of aircraft; and as adjustable supports for heavy loads, such as the foundations of houses. Description A screw jack consists of a heavy-duty vertical screw with a load table mounted on its top, which screws into a threaded hole in a stationary support frame with a wide base resting on the ground. A rotating collar on the head of the screw has holes into which the handle, a metal bar, fits. When the handle is turned clockwise, the screw moves further out of the base, lifting the load resting on the load table. In order to support large load forces, the screw is usually formed with Acme threads. Advantages An advantage of jackscrews over some other types of jack is that they are ''self-locking'', which means when the rotational force on the screw is removed, it will rema ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Ebon Atoll
Ebon Atoll (Marshallese language, Marshallese: , ) is a coral atoll of 22 islands in the Pacific Ocean, forming a legislative district of the Ralik Chain of the Marshall Islands. Its land area is , and it encloses a deep lagoon with an area of . A winding passage, the Ebon Channel, leads to the lagoon from the southwest edge of the atoll. Ebon Atoll is approximately south of Jaluit, and it is the southernmost land mass of the Marshall Islands, on the southern extremity of the Ralik Chain. In documents and accounts from the 1800s, it was also known as Boston, Covell's Group, Fourteen Islands, and Linnez. History Ebon Atoll was visited by commercial whaling vessels in the 19th century. The first such vessel on record was the ''Newark'' in 1837. The last whaler known to have visited was the ''Andrew Hicks'' in 1905. The schooner ''Glencoe'' was taken and its crew massacred by Marshallese at Ebon in 1851 – one of three vessels attacked in the Marshall Islands in 1851 and 1 ...

Pearl Harbor
Pearl Harbor is an American lagoon harbor on the island of Oahu, Hawaii, west of Honolulu. It was often visited by the Naval fleet of the United States, before it was acquired from the Hawaiian Kingdom by the U.S. with the signing of the Reciprocity Treaty of 1875. Much of the harbor and surrounding lands are now a United States Navy deep-water naval base. It is also the headquarters of the United States Pacific Fleet. The U.S. government first obtained exclusive use of the inlet and the right to maintain a repair and coaling station for ships here in 1887. The surprise attack by the Imperial Japanese Navy on December 7, 1941, led the United States to declare war on the Empire of Japan, making the attack on Pearl Harbor the immediate cause of the United States' entry into World War II. History Pearl Harbor was originally an extensive shallow embayment called ''Wai Momi'' (meaning, “Waters of Pearl”) or ''Puuloa'' (meaning, “long hill”) by the Hawaiians. Puuloa was r ...

Naval Transportation Service
Military Sealift Command (MSC) is an organization that controls the replenishment and military transport ships of the United States Navy. Military Sealift Command has the responsibility for providing sealift and ocean transportation for all US military services as well as for other government agencies. It first came into existence on 9 July 1949 when the Military Sea Transportation Service (MSTS) became solely responsible for the Department of Defense's ocean transport needs. The MSTS was renamed the Military Sealift Command in 1970. Military Sealift Command ships are made up of a core fleet of ships owned by the United States Navy and others under long-term-charter augmented by short-term or voyage-chartered ships. During a time charter MSC takes control of a merchant ship and operates it for the chartered amount of time. During this time the ship is crewed by civilian mariners and MSC pays for all expenses. Time chartered ships are not subject to inspections from foreign gover ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shakedown Cruise
Shakedown cruise is a nautical term in which the performance of a ship is tested. Generally, shakedown cruises are performed before a ship enters service or after major changes such as a crew change, repair or overhaul. The shakedown cruise simulates working conditions for the vessel, for various reasons. For most new ships, the major reasons are to familiarise a crew with a new vessel and to ensure all of the ship's systems are functional. Overview If the ship is the first of its class, it will likely also be performing its sea trials, a test of its performance. In this context, 'shakedown cruise' and 'sea trials' may be used interchangeably, though each has a slightly different meaning. In such a case, it is likely that the ship's systems will be pushed to redline, or maximum capacity, to demonstrate the class's speed and other important traits. Until bested by another ship of the same class, this shakedown performance will be the standard of the class's capabilities, a ...

Cargo Ship
A cargo ship or freighter is a merchant ship that carries cargo, goods, and materials from one port to another. Thousands of cargo carriers ply the world's seas and oceans each year, handling the bulk of international trade. Cargo ships are usually specially designed for the task, often being equipped with crane (machine), cranes and other mechanisms to load and unload, and come in all sizes. Today, they are almost always built of welded steel, and with some exceptions generally have a life expectancy of 25 to 30 years before being scrapped. Definitions The words ''cargo'' and ''freight'' have become interchangeable in casual usage. Technically, "cargo" refers to the goods carried aboard the ship for hire, while "freight" refers to the act of carrying of such cargo, but the terms have been used interchangeably for centuries. Generally, the modern ocean shipping business is divided into two classes: # Liner business: typically (but not exclusively) container vessels (where ...
