Turning Basin
A turning basin, winding basin or swinging basin is a wider body of water, either located at the end of a ship canal or in a port to allow cargo ships to turn and reverse their direction of travel, or to enable long narrow barges in a canal to turn a sharp corner. For a complete 180-degree turnaround, the width of the basin must be more than the length of the longest vessel normally traversing the waterway. Onboard bow thrusters or tugboat A tugboat or tug is a marine vessel that manoeuvres other vessels by pushing or pulling them, with direct contact or a tow line. These boats typically tug ships in circumstances where they cannot or should not move under their own power, su ...s may assist in manoeuvering the ship. In seaports the turning basins is often not a real physical basin, but a designated area in the harbour basin where turning is possible and mooring is prohibited. In the example from Gdynia the plan is to enlarge the existing turning basin by removing a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Canal
A ship canal is a canal especially intended to accommodate ships used on the oceans, seas, or lakes to which it is connected. Definition Ship canals can be distinguished from barge canals, which are intended to carry barges and other vessels specifically designed for river and/or canal navigation. Ships capable of navigating large bodies of open water typically have more draft, and are higher above the water than vessels for inland navigation. A ship canal therefore typically offers deeper water and higher bridge clearances than a barge canal suitable for vessels of similar length and width constraints. Ship canals may be specially constructed from the start to accommodate ships, or less frequently they may be enlarged barge canals or ''canalized '' or channelized rivers. There are no specific minimum dimensions for ship canals, with the size being largely dictated by the size of ships in use nearby at the time of construction or enlargement. Ship canals may be constructed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pegasus Barge
The Space Shuttle external tank (ET) was the component of the Space Shuttle launch vehicle that contained the liquid hydrogen fuel and liquid oxygen oxidizer. During lift-off and ascent it supplied the fuel and oxidizer under pressure to the three RS-25 main engines in the orbiter. The ET was jettisoned just over 10 seconds after main engine cut-off (MECO) and it re-entered the Earth's atmosphere. Unlike the Solid Rocket Boosters, external tanks were not re-used. They broke up before impact in the Indian Ocean (or Pacific Ocean in the case of direct-insertion launch trajectories), away from shipping lanes and were not recovered. Overview The ET was the largest element of the Space Shuttle, and when loaded, it was also the heaviest. It consisted of three major components: * the forward liquid oxygen (LOX) tank * an unpressurized intertank that contains most of the electrical components * the aft liquid hydrogen (LH2) tank; this was the largest part, but it was relatively li ...

Canal Basin
A canal basin is (particularly in the United Kingdom) an expanse of waterway alongside or at the end of a canal, and wider than the canal, constructed to allow boats to moor or unload cargo without impeding the progress of other traffic, and to allow room for turning, thus serving as a winding hole. For inland waterways, a basin may be thought of as a land-locked harbour.Shorter Oxford Dictionary - Vol 1 - "basin" A basin was often associated with wharves around its perimeter, to support commercial users. In modern times, canal basins are more usually used to moor residential and recreational narrowboats.

Narrowboat
A narrowboat is a particular type of canal boat, built to fit the narrow locks of the United Kingdom. The UK's canal system provided a nationwide transport network during the Industrial Revolution, but with the advent of the railways, commercial canal traffic gradually diminished and the last regular long-distance transportation of goods by canal had virtually disappeared by 1970. However, some commercial traffic continued. From the 1970s onward narrowboats were gradually being converted into permanent residences or as holiday lettings. Currently, about 8580 narrowboats are registered as 'permanent homes' on Britain's waterway system and represent a growing alternative community living on semi-permanent moorings or continuously cruising. For any boat to enter a narrow lock, it must be under wide, so most narrowboats are nominally wide. A narrowboat's maximum length is generally , as anything longer will be unable to navigate much of the British canal network, because the ...

Nottingham Canal
The Nottingham Canal is a canal in the English counties of Nottinghamshire and Derbyshire. As built, it comprised a long main line between the River Trent just downstream of Trent Bridge in Nottingham and Langley Mill in Derbyshire. At the same time as the main line of the canal was built by its proprietors, the separate Trent Navigation Company built the Beeston Cut, from the main line at Lenton in Nottingham to rejoin the River Trent upstream of Nottingham, thus bypassing the difficult section of navigation through Trent Bridge. The section of the main line between Trent Bridge and Lenton, together with the Beeston Cut, is still in use, forming part of the navigation of the River Trent and sometimes referred to as the Nottingham & Beeston Canal. The remainder of the main line of the canal beyond Lenton has been abandoned and partially filled. The canal leaves the River Trent by Meadow Lane Lock and runs close to Nottingham city centre, serving a number of wharves in the cit ...

Kennedy Space Center
The John F. Kennedy Space Center (KSC, originally known as the NASA Launch Operations Center), located on Merritt Island, Florida, is one of the National Aeronautics and Space Administration's (NASA) ten field centers. Since December 1968, KSC has been NASA's primary launch center of human spaceflight. Launch operations for the Apollo, Skylab and Space Shuttle programs were carried out from Kennedy Space Center Launch Complex 39 and managed by KSC. Located on the east coast of Florida, KSC is adjacent to Cape Canaveral Space Force Station (CCSFS). The management of the two entities work very closely together, share resources and operate facilities on each other's property. Though the first Apollo flights and all Project Mercury and Project Gemini flights took off from the then-Cape Canaveral Air Force Station, the launches were managed by KSC and its previous organization, the Launch Operations Directorate. Starting with the fourth Gemini mission, the NASA launch con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vehicle Assembly Building
The Vehicle Assembly Building (originally the Vertical Assembly Building), or VAB, is a large building at NASA's Kennedy Space Center (KSC), designed to assemble large pre-manufactured space vehicle components, such as the massive Saturn V and the Space Shuttle, and stack them vertically onto one of three mobile launcher platforms used by NASA.

Turning Basin Gdynia
Turning is a machining process in which a cutting tool, typically a non-rotary tool bit, describes a helix toolpath by moving more or less linearly while the workpiece rotates. Usually the term "turning" is reserved for the generation of ''external'' surfaces by this cutting action, whereas this same essential cutting action when applied to ''internal'' surfaces (holes, of one kind or another) is called " boring". Thus the phrase "turning and boring" categorizes the larger family of processes known as lathing. The cutting of faces on the workpiece, whether with a turning or boring tool, is called "facing", and may be lumped into either category as a subset. Turning can be done manually, in a traditional form of lathe, which frequently requires continuous supervision by the operator, or by using an automated lathe which does not. Today the most common type of such automation is computer numerical control, better known as CNC. (CNC is also commonly used with many other type ...

Port
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 ...

Tugboat
A tugboat or tug is a marine vessel that manoeuvres other vessels by pushing or pulling them, with direct contact or a tow line. These boats typically tug ships in circumstances where they cannot or should not move under their own power, such as in crowded harbour or narrow canals, or cannot move at all, such as barges, disabled ships, log rafts, or oil platforms. Some are ocean-going, some are icebreakers or salvage tugs. Early models were powered by steam engines, long ago superseded by diesel engines. Many have deluge gun water jets, which help in firefighting, especially in harbours. Types Seagoing Seagoing tugs (deep-sea tugs or ocean tugboats) fall into four basic categories: #The standard seagoing tug with model bow that tows almost exclusively by way of a wire cable. In some rare cases, such as some USN fleet tugs, a synthetic rope hawser may be used for the tow in the belief that the line can be pulled aboard a disabled ship by the crew owing to its lightn ...

Bow Thruster
Manoeuvering thruster (bow thruster or stern thruster) is a transversal propulsion device built into, or mounted to, either the bow or stern, of a ship or boat to make it more manoeuvrable. Bow thrusters make docking easier, since they allow the captain to turn the vessel to port or starboard side, without using the main propulsion mechanism which requires some forward motion for turning; The effectiveness of a thruster is curtailed by any forward motion due to the Coandă effect. A stern thruster is of the same principle, fitted at the stern. Large ships might have multiple bow thrusters and stern thrusters. Tunnel thrusters Large vessels usually have one or more tunnel thrusters built into the bow, below the waterline. An impeller in the tunnel can create thrust in either direction that makes the ship turn. Most tunnel thrusters are driven by electric motors, but some are hydraulically powered. These bow thrusters, also known as tunnel thrusters, may allow the ship t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
