MS Oasis Of The Seas
''Oasis of the Seas'' is a cruise ship operated by Royal Caribbean International. She is the first of her class, whose ships are the largest passenger ships in the world. Her hull was laid down in November 2007 and she was completed and delivered to Royal Caribbean in October 2009. At the time of construction, ''Oasis of the Seas'' set a new capacity record of carrying over 6,000 passengers. The first of her class, she was joined by sister ships ''Allure of the Seas'' in December 2010, ''Harmony of the Seas'' in May 2016, ''Symphony of the Seas'' in April 2018, and ''Wonder of the Seas'' in March 2022. ''Oasis of the Seas'' conducts cruises of the Caribbean from her home port of PortMiami in Miami, Florida. ''Oasis of the Seas'' surpassed the cruise ships (also owned by Royal Caribbean) to become the largest cruise ship in the world at that time. She was herself surpassed by her sister ship ''Allure of the Seas'', which is longer, although this may have been caused by ambi ...

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 to d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Azimuth Thruster
An azimuth thruster is a configuration of marine propellers placed in pods that can be rotated to any horizontal angle (azimuth), making a rudder unnecessary. These give ships better maneuverability than a fixed propeller and rudder system. Types of azimuth thrusters There are two major variants, based on the location of the motor: # Mechanical transmission, which connects a motor inside the ship to the outboard unit by gearing. The motor may be diesel or diesel-electric. Depending on the shaft arrangement, mechanical azimuth thrusters are divided into L-drive and Z-drive. An L-drive thruster has a vertical input shaft and a horizontal output shaft with one right-angle gear. A Z-drive thruster has a horizontal input shaft, a vertical shaft in the rotating column and a horizontal output shaft, with two right-angle gears. # Electrical transmission, more commonly called pods, where an electric motor is fitted in the pod itself, connected directly to the propeller withou ...

Engine
An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy. Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power generation), heat energy (e.g. geothermal), chemical energy, electric potential and nuclear energy (from nuclear fission or nuclear fusion). Many of these processes generate heat as an intermediate energy form, so heat engines have special importance. Some natural processes, such as atmospheric convection cells convert environmental heat into motion (e.g. in the form of rising air currents). Mechanical energy is of particular importance in transportation, but also plays a role in many industrial processes such as cutting, grinding, crushing, and mixing. Mechanical heat engines convert heat into work via various thermodynamic processes. The internal combustion engine is perhaps the most common example of a mechanical heat engine, in ...

V12 Engine
A V12 engine is a twelve-cylinder piston engine where two banks of six cylinders are arranged in a V configuration around a common crankshaft. V12 engines are more common than V10 engines. However, they are less common than V8 engines. The first V12 engine was built in 1904 for use in racing boats. Due to the balanced nature of the engine and the smooth delivery of power, V12 engines were found in early luxury automobiles, boats, aircraft, and tanks. Aircraft V12 engines reached their apogee during World War II, following which they were mostly replaced by jet engines. In Formula One racing, V12 engines were common during the late 1960s and early 1990s. Applications of V12 engines in the 21st century have been as marine engines, in railway locomotives, as large stationary power as well as in some European sports and luxury cars. Design Balance and smoothness Each bank of a V12 engine essentially functions as a straight-six engine, which by itself has perfect primary a ...

Common Rail
Common rail direct fuel injection is a direct fuel injection system built around a high-pressure (over ) fuel rail feeding solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors (or pump nozzles). High-pressure injection delivers power and fuel consumption benefits over earlier lower pressure fuel injection, by injecting fuel as a larger number of smaller droplets, giving a much higher ratio of surface area to volume. This provides improved vaporization from the surface of the fuel droplets, and so more efficient combining of atmospheric oxygen with vaporized fuel delivering more complete combustion. Common rail injection is widely used in diesel engines. It is also the basis of gasoline direct injection systems used on petrol engines. History Vickers pioneered the use of common rail injection in submarine engines. Vickers engines with the common rail fuel system were first used in 1916 in the G-class submarines. It used four plunger pumps to deliver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V16 Engine
A V16 engine is a sixteen-cylinder piston engine where two banks of eight cylinders are arranged in a V configuration around a common crankshaft. V16 engines are less common than engines with fewer cylinders, such as V8 and V12 engines. Each bank of a V16 engine can be thought of as a straight-8, a design that can be inherently balanced. Most V16 engines have a 45° bank angle. The first use of a V16 engine was in the 1910 Antoinette VII experimental aircraft, followed by several cars in the 1930s. Today, the most common applications for V16 engines are railroad locomotives, marine craft, and stationary power generators. Automotive applications Production cars The first production car to use a V16 engine was the Cadillac V-16, introduced in January 1930. The Cadillac V16 engine was initially produced with a displacement of , OHV and a V-angle of 45 degrees. For the 1938 Series 90, the engine was revised to a displacement of , a flathead valvetrain and a V-angle of 135 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oasis Of The Seas Lifeboat
In ecology, an oasis (; ) is a fertile area of a desert or semi-desert environment'ksar''with its surrounding feeding source, the palm grove, within a relational and circulatory nomadic system.” The location of oases has been of critical importance for trade and transportation routes in desert areas; caravans must travel via oases so that supplies of water and food can be replenished. Thus, political or military control of an oasis has in many cases meant control of trade on a particular route. For example, the oases of Awjila, Ghadames and Kufra, situated in modern-day Libya, have at various times been vital to both north–south and east–west Trans-Saharan trade, trade in the Sahara Desert. The location of oases also informed the Darb El Arba'īn trade route from Sudan to Egypt, as well as the caravan route from the Niger River to Tangier, Morocco. The Silk Road “traced its course from water hole to water hole, relying on oasis communities such as Turpan in China and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p.5. This is accomplished by means of its "draft marks" (or "load lines"). A ...

Gross Tonnage
Gross tonnage (GT, G.T. or gt) is a nonlinear measure of a ship's overall internal volume. Gross tonnage is different from gross register tonnage. Neither gross tonnage nor gross register tonnage should be confused with measures of mass or weight such as deadweight tonnage or displacement. Gross tonnage, along with net tonnage, was defined by the ''International Convention on Tonnage Measurement of Ships, 1969'', adopted by the International Maritime Organization (IMO) in 1969, and came into force on 18 July 1982. These two measurements replaced gross register tonnage (GRT) and net register tonnage (NRT). Gross tonnage is calculated based on "the moulded volume of all enclosed spaces of the ship" and is used to determine things such as a ship's manning regulations, safety rules, registration fees, and port dues, whereas the older gross register tonnage is a measure of the volume of only certain enclosed spaces. History The International Convention on Tonnage Measurement o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Largest Cruise Ships
The Symphony of the Seas is the world's largest passenger cruise ship. Measuring 362m (1,188ft) long, the ship has a capacity of nearly 9,000 passengers and crew, features 23 swimming pools and 18 decks. Cruise ships are large passenger ships used mainly for vacationing. Unlike ocean liners, which are used for pwet transport, they typically embark on round-trip voyages to various ports-of-call, where passengers may go on tours known as "shore excursions". They can carry thousands of passengers in a single trip, and are some of the largest ships in the world by gross tonnage(GT), bigger than many cargo ships. Cruise ships started to exceed ocean liners in size and capacity in the mid-1990s; before then, few were more than 50,000GT. In the decades since, the size of the largest vessels has more than doubled. There have been nine or more new cruise ships added every year since 2001, most of which are 100,000GT or greater. In the two decades between 1988 and 2009, the largest cruise s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
