MV Reina Del Pacifico
MV ''Reina del Pacifico'' was a ocean liner of the Pacific Steam Navigation Company. She was built in Northern Ireland in 1930–31 and sailed between Liverpool and the Pacific coast of South America until 1939. She served as a troop ship from 1939 until 1946. She returned to her civilian route in 1948 and was scrapped in 1958. Building Harland and Wolff built the ship at Belfast, launching her on 23 September 1930 and completing her on 24 March 1931. Harland and Wolff had a license to build Burmeister & Wain marine diesel engines. ''Reina del Pacifico'' was built with four sets of these engines driving four propellers. They developed a total of 5,500 BHP or 2,844 NHP at 145 rpm, giving her her a speed of . The ship was briefly the largest and fastest motor liner of her time. These records soon passed to larger and faster ships being built in Italy and Belgium, but for some years ''Reina del Pacifico'' remained the largest ship operating scheduled services to the Pacific coa ...

Ship's Bell
A ship's bell is a bell on a ship that is used for the indication of time as well as other traditional functions. The bell itself is usually made of brass or bronze, and normally has the ship's name engraved or cast on it. Strikes Timing of ship's watches Unlike civil clock bells, the strikes of a ship's bell do not accord to the number of the hour. Instead, there are eight bells, one for each half-hour of a four-hour watch. In the age of sailing, watches were timed with a 30-minute hourglass. Bells would be struck every time the glass was turned, and in a pattern of pairs for easier counting, with any odd bells at the end of the sequence. Classical system The classical, or traditional, system was: Most of the crew of a ship would be divided into two to four groups, called watches. Each watch would take its turn with the essential activities of manning the helm, navigating, trimming sails, and keeping a lookout. The hours between 16:00 and 20:00 are so arranged because tha ...

Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Promenade Deck
The promenade deck is a deck found on several types of passenger ships and riverboats. It usually extends from bow to stern, on both sides, and includes areas open to the outside, resulting in a continuous outside walkway suitable for ''promenading'', (i.e., walking) thus the name. On older passenger ships, the promenade deck was simply the top outside deck below the superstructure, and was enclosed by a railing. Lifeboats are typically kept on davits accessible from the promenade. On a Mississippi riverboat, the promenade deck is the second deck, or floor, up from the waterline, above the main deck, and below the Texas deck. On modern cruise ships with superstructures as high and broad as the hull, the promenade deck is often largely enclosed, with railing-lined "cutouts" and wooden decking to recall the old days. The promenade may be used for jogging as well as walking, and signs indicate the mileage. Centerline promenade Many cruise ships and cruiseferries built by Aker ...

Moresque
Moresque is an obsolete alternative term to "Moorish" in English, and in the arts has some specific meanings. By itself, the word is used to describe the stylized plant-based forms of tendrils and leaves found in ornament and decoration in the applied arts in Renaissance Europe that are derived from the arabesque patterns of Islamic ornament. Like their Islamic ancestors, they differ from the typical European plant scroll in being many-branched and spreading rather than forming a line in one direction. The use of half-leaves with their longest side running along the stem is typical for both. First found in 15th-century Italy, especially Venice, moresques continue in the Mannerist and Northern Mannerist styles of the 16th century. Figures Another, related, meaning was defined in 1611 by Randle Cotgrave's ''A Dictionarie of the French and English Tongues'' as: "a rude or anticke painting, or carving, wherin the feet and tayles of beasts, &c, are intermingled with, or made t ...

El Escorial
El Escorial, or the Royal Site of San Lorenzo de El Escorial ( es, Monasterio y Sitio de El Escorial en Madrid), or Monasterio del Escorial (), is a historical residence of the King of Spain located in the town of San Lorenzo de El Escorial, up the valley ( road distance) from the town of El Escorial and about northwest of the Spanish capital Madrid. Built between 1563 and 1584 by order of King Philip II (who reigned 1556–1598), El Escorial is the largest Renaissance building in the world. It is one of the Spanish royal sites and functions as a monastery, basilica, royal palace, pantheon, library, museum, university, school, and hospital. El Escorial consists of two architectural complexes of great historical and cultural significance: the royal monastery itself and '' La Granjilla de La Fresneda'', a royal hunting lodge and monastic retreat about 5 kilometres away. These sites have a dual nature: during the 16th and 17th centuries, they were places in which the power of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Revolutions Per Minute
Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or with the notation min−1) is a unit of rotational speed or rotational frequency for rotating machines. Standards ISO 80000-3:2019 defines a unit of rotation as the dimensionless unit equal to 1, which it refers to as a revolution, but does not define the revolution as a unit. It defines a unit of rotational frequency equal to s−1. The superseded standard ISO 80000-3:2006 did however state with reference to the unit name 'one', symbol '1', that "The special name revolution, symbol r, for this unit is widely used in specifications on rotating machines." The International System of Units (SI) does not recognize rpm as a unit, and defines the unit of frequency, Hz, as equal to s−1. :\begin 1~&\text &&=& 60~&\text \\ \frac~&\text &&=& 1~&\text \end A corresponding but distinct quantity for describing rotation is angular velocity, for which the SI unit is the ra ...

Marine Diesel Engine
Marine propulsion is the mechanism or system used to generate thrust to move a watercraft through water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or internal combustion engine driving a propeller, or less frequently, in pump-jets, an impeller. Marine engineering is the discipline concerned with the engineering design process of marine propulsion systems. Human-powered paddles and oars, and later, sails were the first forms of marine propulsion. Rowed galleys, some equipped with sail, played an important early role in early human seafaring and warfares. The first advanced mechanical means of marine propulsion was the marine steam engine, introduced in the early 19th century. During the 20th century it was replaced by two-stroke or four-stroke diesel engines, outboard motors, and gas turbine engines on faster ships. Marine nuclear reactors, which appeared in the 1950s, pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burmeister & Wain
Burmeister & Wain was a large established Danish shipyard and leading diesel engine producer headquartered in Copenhagen, Denmark. Founded by two Danes and an Englishman, its earliest roots stretch back to 1846. Over its 150-year history, it grew successfully into a strong company through the end of the 1960s. In the 1970s, global competitive pressures, particularly from the far east, began to take their toll. In 1980, B&W became MAN B&W Diesel A/S, part of MAN B&W Diesel Group, a subsidiary of the German corporation MAN AG, with operations worldwide. The company still maintains operations at three main sites in Denmark for manufacturing, servicing, and licensing of its two-stroke engines and complete propulsion systems. History Origins Hans Heinrich Baumgarten (1806–1875) was from the town of Halstenbek near Pinneberg, in the Duchy of Holstein, an area of Germany that was then under the rule of the king of Denmark. He was apprenticed as a coffin maker by a farmer who ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
License
A license (or licence) is an official permission or permit to do, use, or own something (as well as the document of that permission or permit). A license is granted by a party (licensor) to another party (licensee) as an element of an agreement between those parties. In the case of a license issued by a government, the license is obtained by applying for it. In the case of a private party, it is by a specific agreement, usually in writing (such as a lease or other contract). The simplest definition is "A license is a promise not to sue," because a license usually either permits the licensed party to engage in an activity which is illegal, and subject to prosecution, without the license (e.g. fishing, driving an automobile, or operating a broadcast radio or television station), or it permits the licensed party to do something that would violate the rights of the licensing party (e.g. make copies of a copyrighted work), which, without the license, the licensed party could be ...

Troopship
A troopship (also troop ship or troop transport or trooper) is a ship used to carry soldiers, either in peacetime or wartime. Troopships were often drafted from commercial shipping fleets, and were unable land troops directly on shore, typically loading and unloading at a seaport or onto smaller vessels, either tenders or barges. Attack transports, a variant of ocean-going troopship adapted to transporting invasion forces ashore, carry their own fleet of landing craft. Landing ships beach themselves and bring their troops directly ashore. History Ships to transport troops were used in Antiquity. Ancient Rome used the navis lusoria, a small vessel powered by rowers and sail, to move soldiers on the Rhine and Danube. The modern troopship has as long a history as passenger ships do, as most maritime nations enlisted their support in military operations (either by leasing the vessels or by impressing them into service) when their normal naval forces were deemed insufficient fo ...

Northern Ireland
Northern Ireland ( ga, Tuaisceart Éireann ; sco, label= Ulster-Scots, Norlin Airlann) is a part of the United Kingdom, situated in the north-east of the island of Ireland, that is variously described as a country, province or region. Northern Ireland shares an open border to the south and west with the Republic of Ireland. In 2021, its population was 1,903,100, making up about 27% of Ireland's population and about 3% of the UK's population. The Northern Ireland Assembly (colloquially referred to as Stormont after its location), established by the Northern Ireland Act 1998, holds responsibility for a range of devolved policy matters, while other areas are reserved for the UK Government. Northern Ireland cooperates with the Republic of Ireland in several areas. Northern Ireland was created in May 1921, when Ireland was partitioned by the Government of Ireland Act 1920, creating a devolved government for the six northeastern counties. As was intended, Northern Ireland ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
