Andrea Doria (ocean Liner)
SS ''Andrea Doria'' () was a luxury transatlantic ocean liner of the Italian Line (Società di navigazione Italia), put into service in 1953. She is widely known from the extensive media coverage of her sinking in 1956, which included the remarkably successful rescue of 1,660 of her 1,706 passengers and crew. Named after the 16th-century Genoa, Genoese admiral Andrea Doria, the ship had a gross register tonnage of 29,100 and a capacity of about 1,200 passengers and 500 crew. Of all Italy's ships at the time, ''Andrea Doria'' was the largest, fastest and supposedly safest. Ceremonial ship launching, Launched on 16 June 1951, she was home-ported in Genoa, and began her maiden voyage on 14 January 1953. On 25 July 1956, the New York City–bound vessel was approaching the coast of Nantucket, Massachusetts, United States. There was thick fog and when ''Andrea Doria'' finally noticed the eastbound passenger liner of the Swedish American Line, they were already too close to each ot ...

Andrea Doria
Andrea Doria, Prince of Melfi (; ; 30 November 146625 November 1560) was an Italian statesman, ', and admiral, who played a key role in the Republic of Genoa during his lifetime. From 1528 until his death, Doria exercised a predominant influence in the councils of the Genoese republic, and was considered the foremost naval leader in Europe at his time. He became Charles V, Holy Roman Emperor, Holy Roman Emperor Charles V's grand admiral, a position he employed both to protect Genoa's independence and to maintain his own control over the city. He also acted as a privateer with the ships he owned in order to increase his wealth. His fleet helped secure the imperial naval lines between Spain and Italy, although he had a mixed success against the eminent threat of the Ottoman Empire, Ottoman navy.Christina Shaw, ''Barons and Castellans: The Military Nobility of Renaissance Italy'' 2014, Brill, ISBN 9789004282766, p. 133-134 As the ruler of Genoa, Doria reformed the Republic's cons ...

Turbine
A turbine ( or ) (from the Greek , ''tyrbē'', or Latin ''turbo'', meaning vortex) is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced can be used for generating electrical power when combined with a generator.Munson, Bruce Roy, T. H. Okiishi, and Wade W. Huebsch. "Turbomachines." Fundamentals of Fluid Mechanics. 6th ed. Hoboken, NJ: J. Wiley & Sons, 2009. Print. A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor. Gas, steam, and water turbines have a casing around the blades that contains and controls the working fluid. Modern steam turbines frequently employ both reaction and impulse in the same unit, typically varying the degree of reaction and impulse from the blade root to its periphery.

Andrea Doria On Slip
Andrea is a given name which is common worldwide for both males and females, cognate to Andreas, Andrej and Andrew. Origin of the name The name derives from the Greek word ἀνήρ (''anēr''), genitive ἀνδρός (''andrós''), that refers to man as opposed to woman (whereas ''man'' in the sense of ''human being'' is ἄνθρωπος, ''ánthropos''). The original male Greek name, ''Andréas'', represents the hypocoristic, with endearment functions, of male Greek names composed with the ''andr-'' prefix, like Androgeos (''man of the earth''), Androcles (''man of glory''), Andronikos (''man of victory''). In the year 2006, it was the third most popular name in Italy with 3.1% of newborns. It is part of the Italian male names ending in ''a'', some others being Elia ( Elias), Enea ( Aeneas), Luca ( Lucas), Mattia ( Matthias), Nicola (Nicholas), Tobia ( Tobias). In recent and past times it has also been used on occasion as a female name in Italy and in Spain, wh ...

Nantucket
Nantucket () is an island in the state of Massachusetts in the United States, about south of the Cape Cod peninsula. Together with the small islands of Tuckernuck Island, Tuckernuck and Muskeget Island, Muskeget, it constitutes the Town and County of Nantucket, a Consolidated city-county, combined county/town government. Nantucket is the southeasternmost town in both Massachusetts and the New England region. The name "Nantucket" is adapted from similar Eastern Algonquian languages, Algonquian names for the island. Nantucket is a tourism, tourist destination and summer colony. Due to tourists and seasonal residents, the population of the island increases to around 80,000 during the summer months. The average sale price for a single-family home was $2.3 million in the first quarter of 2018. The National Park Service cites Nantucket, designated a National Historic Landmark District in 1966, as being the "finest surviving architectural and environmental example of a late 18th- an ...

List (watercraft)
The angle of list is the degree to which a vessel heels (leans or tilts) to either port or starboard at equilibrium—with no external forces acting upon it. If a listing ship goes beyond the point where a righting moment will keep it afloat, it will capsize and potentially sink. Listing is caused by the off-centerline distribution of weight aboard due to uneven loading or to flooding. By contrast, ''roll'' is the dynamic movement from side to side caused by waves. See also * Angle of loll * Heeling (sailing) * Capsizing * Metacentric height *Ship stability Ship stability is an area of naval architecture and ship design that deals with how a ship behaves at sea, both in still water and in waves, whether intact or damaged.

Motorboat
A motorboat or powerboat is a boat that is exclusively powered by an engine; faster examples may be called "speedboats". Some motorboats are fitted with inboard engines, others have an outboard motor installed on the rear, containing the internal combustion engine, the gearbox and the propeller in one portable unit. An inboard-outboard contains a hybrid of an inboard and an outboard, where the internal combustion engine is installed inside the boat, and the gearbox and propeller are outside. There are two configurations of an inboard, V-drive and direct drive. A direct drive has the powerplant mounted near the middle of the boat with the propeller shaft straight out the back, where a V-drive has the powerplant mounted in the back of the boat facing backwards having the shaft go towards the front of the boat then making a ''V'' towards the rear. Overview A motorboat is a small craft with one or more engines for propulsion. Motorboats are commonly used for work, recreation ...

Launch (boat)
Launch is a name given to several different types of boat. The wide range of usage of the name extends from utilitarian craft through to pleasure boats built to a very high standard. In naval use, the launch was introduced as a ship's boat towards the end of the 17th century. On each warship, the launch was usually the largest boat out of those carried aboard. It could be propelled by oar or sail, with this type remaining in service into the 20th century. Steam launches were introduced on a trial basis in 1867, but as steam-powered ship's boats became more common, the majority were steam pinnaces. Other military examples were the various motor launches used in the 20th century, employed for harbour defence, anti-submarine patrols, escorting coastal convoys, minesweeping and recovering aircrew from crashed aircraft. Generally these were decked boats, some of which were capable of fast speeds. A powered boat operated by a regulatory or official organisation may be termed a ...

Lifeboat (shipboard)
A lifeboat or liferaft is a small, rigid or inflatable boat carried for emergency evacuation in the event of a disaster aboard a ship. Lifeboat drills are required by law on larger commercial ships. Rafts (raft, liferafts) are also used. In the military, a lifeboat may double as a whaleboat, dinghy, or Captain's gig, gig. The ship's tenders of cruise ships often double as lifeboats. Recreational sailors usually carry inflatable liferafts, though a few prefer small proactive lifeboats that are harder to sink and can be sailed to safety. Inflatable lifeboats may be equipped with auto-inflation (carbon dioxide or nitrogen) canisters or mechanical pumps. A quick release and pressure release mechanism is fitted on ships so that the canister or pump automatically inflates the lifeboat, and the lifeboat breaks free of the sinking vessel. Commercial aircraft are also required to carry auto-inflating liferafts in case of an emergency water landing; offshore oil platforms also have life ...

Radar
Radar is a system that uses radio waves to determine the distance ('' ranging''), direction ( azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain. The term ''RADAR'' was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging". The term ''radar'' has since entered English and other languages as an anacronym, a common noun, losing all capitalization. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwave domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving ...

Bulkhead (partition)
A bulkhead is an upright wall within the hull (watercraft), hull of a ship, within the fuselage of an airplane, or a car. Other kinds of partition elements within a ship are deck (ship), decks and deckheads. Etymology The word ''bulki'' meant "cargo" in Old Norse. During the 15th century sailors and builders in Europe realized that walls within a vessel would prevent cargo from shifting during passage. In shipbuilding, any vertical panel was called a head. So walls installed abeam (side-to-side) in a vessel's hull were called "bulkheads". Now, the term bulkhead applies to every vertical panel aboard a ship, except for the hull itself. History Bulkheads were known to the ancient Greeks, who employed bulkheads in triremes to support the back of rams. By the Athenian trireme era (500 BC), the hull was strengthened by enclosing the bow behind the ram, forming a bulkhead compartment. Instead of using bulkheads to protect ships against rams, Greeks preferred to reinforce the hull ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Double Hull
A double hull is a ship hull design and construction method where the bottom and sides of the ship have two complete layers of watertight hull surface: one outer layer forming the normal hull of the ship, and a second inner hull which is some distance inboard, typically by a few feet, which forms a redundant barrier to seawater in case the outer hull is damaged and leaks. The space between the two hulls is sometimes used for storage of ballast water. Double hulls are a more extensive safety measure than double bottoms, which have two hull layers only in the bottom of the ship but not the sides. In low-energy collisions, double hulls can prevent flooding beyond the penetrated compartment. In high-energy collisions, however, the distance to the inner hull is not sufficient and the inner compartment is penetrated as well. Double hulls or double bottoms have been required in all passenger ships for decades as part of the Safety Of Life At Sea or SOLAS Convention. Uses Double hul ...
