TEV Rangatira (1971)
TEV ''Rangatira'' was a roll-on/roll-off vehicle and passenger ferry launched in 1971 for the Union Steam Ship Company of New Zealand. She is significant for having been the World's last surviving passenger ship with steam-powered turbo-electric transmission. (Modern turbo-electric ships, including and s such as ''Celebrity Millennium'', have gas turbines.) ''Rangatira'' had a varied existence, including serving as an accommodation ship and barracks ship between 1977 and 1983. The Union Company sold her in 1986 and she returned to being a ferry. From 1986 onwards, she passed through a succession of owners who renamed her three times and registered her under three different flags of convenience: as ''Queen M'' in 1986, ''Carlo R'' in 1990 and ''Alexander the Great'' in 2001. After a failed attempt to convert the vessel into a cruise ship she was scrapped in 2005. Name ''Rangatira'' is Māori for "chief (male or female), wellborn, noble". The 1971 ship is at least the sixth to ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Māori Language
Māori (), or ('the Māori language'), also known as ('the language'), is an Eastern Polynesian language spoken by the Māori people, the indigenous population of mainland New Zealand. Closely related to Cook Islands Māori, Tuamotuan, and Tahitian, it gained recognition as one of New Zealand's official languages in 1987. The number of speakers of the language has declined sharply since 1945, but a Māori-language revitalisation effort has slowed the decline. The 2018 New Zealand census reported that about 186,000 people, or 4.0% of the New Zealand population, could hold a conversation in Māori about everyday things. , 55% of Māori adults reported some knowledge of the language; of these, 64% use Māori at home and around 50,000 people can speak the language "very well" or "well". The Māori language did not have an indigenous writing system. Missionaries arriving from about 1814, such as Thomas Kendall, learned to speak Māori, and introduced the Latin alphabet. In 1 ...

Barracks Ship
A barracks ship or barracks barge or berthing barge, or in civilian use accommodation vessel or accommodation ship, is a ship or a non-self-propelled barge containing a superstructure of a type suitable for use as a temporary barracks for sailors or other military personnel. A barracks ship, a military form of a dormitory ship, may also be used as a receiving unit for sailors who need temporary residence prior to being assigned to their ship. The United States Navy used to call them Yard Repair Berthing and Messing with designations YRBM and YRBM(L) and now classes them as either Auxiliary Personnel Barracks (APB) or Auxiliary Personnel Lighter (aka barge) (APL). Early use Barrack ships were common during the era of sailing ships when shore facilities were scarce or non-existent. Barrack ships were usually hulks. At times, barrack ships were also used as prison ships for convicts, prisoners of war or civilian internees. Use in World War II ''Barracks ships'' in the comb ...

Cruise Ship
Cruise ships are large passenger ships used mainly for vacationing. Unlike ocean liners, which are used for transport, cruise ships typically embark on round-trip voyages to various ports-of-call, where passengers may go on tours known as "shore excursions". On "cruises to nowhere" or "nowhere voyages", cruise ships make two- to three-night round trips without visiting any ports of call.Compare: Modern cruise ships tend to have less hull strength, speed, and agility compared to ocean liners. However, they have added amenities to cater to water tourists, with recent vessels being described as "balcony-laden floating condominiums". As of December 2018, there were 314 cruise ships operating worldwide, with a combined capacity of 537,000 passengers. Cruising has become a major part of the tourism industry, with an estimated market of $29.4 billion per year, and over 19 million passengers carried worldwide annually . The industry's rapid growth saw nine or more newl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flag Of Convenience
Flag of convenience (FOC) is a business practice whereby a ship's owners register a merchant ship in a ship register of a country other than that of the ship's owners, and the ship flies the civil ensign of that country, called the flag state.Bernaert, 2006, p. 104. The term is often used pejoratively, and although common, the practice is sometimes regarded as contentious. Each merchant ship is required by international law to be registered in a registry created by a country,ICFTU et al., 2002, p. 7. and a ship is subject to the laws of that country, which are used also if the ship is involved in a case under admiralty law. A ship's owners may elect to register a ship in a foreign country so as to avoid the regulations of the owners' country, which may, for example, have stricter safety standards. They may also select a jurisdiction to reduce operating costs, avoiding higher taxes in the owners' country and bypassing laws that protect the wages and working conditions of marin ...

Gas Turbine
A gas turbine, also called a combustion turbine, is a type of continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the direction of flow: * a rotating gas compressor * a combustor * a compressor-driving turbine. Additional components have to be added to the gas generator to suit its application. Common to all is an air inlet but with different configurations to suit the requirements of marine use, land use or flight at speeds varying from stationary to supersonic. A propelling nozzle is added to produce thrust for flight. An extra turbine is added to drive a propeller (turboprop) or ducted fan (turbofan) to reduce fuel consumption (by increasing propulsive efficiency) at subsonic flight speeds. An extra turbine is also required to drive a helicopter rotor or land-vehicle transmission (turboshaft), marine propeller or electrical generator (power turbine). Greater ...

Celebrity Millennium
GTS ''Celebrity Millennium'' (formerly ''Millennium'') is a cruise ship operated by Celebrity Cruises. She is the lead ship of her namesake class, whose ships are powered by gas turbines. Delivered in 2000, she is the oldest operating ship in Celebrity's fleet. History Planning and construction In February 1998, Royal Caribbean signed a letter of intent with Chantiers de l'Atlantique to build two new ships, with an option for two more, that would make up a new class of ships, dubbed the ''Millennium'' class. Designed to be an evolution from Celebrity's ''Century''-class ships, these new ships were originally planned to measure and have a guest capacity of approximately 1,900, and be delivered in June 2000 and January 2001, respectively. The ship was the first new-build vessel for Celebrity following the merger between it and Royal Caribbean, and also Celebrity's first new-build not built by German shipyard Meyer Werft. She was launched on 7 November 1999 from the shipyard. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Union Company
Union Steam Ship Company of New Zealand Limited was once the biggest shipping line in the southern hemisphere and New Zealand's largest private-sector employer. It was incorporated by James Mills in Dunedin in 1875 with the backing of a Scottish shipbuilder, Peter Denny. Bought by shipping giant P&O around the time of World War I it was sold in 1972 to an Australasian consortium and closed at the end of the twentieth century. History James Mills James Mills had worked for Johnny Jones and his Harbour Steam Company. After Jones’ death in 1869 Mills tried twice to float a Union Steam Ship Company of New Zealand Limited without attracting enough interest from local investors but in 1875 he found backing from Scottish shipbuilder Peter Denny in return for Union Steam Ship orders for Denny's Dumbarton shipyard. The Denny-built ''Hawea'' and ''Taupo'', both then large by local standards, arrived in mid 1875 and entered service. Union Steam Ship took over the Harbour Steam Com ...

Roll-on/roll-off
Roll-on/roll-off (RORO or ro-ro) ships are cargo ships designed to carry wheeled cargo, such as cars, motorcycles, trucks, semi-trailer trucks, buses, trailers, and railroad cars, that are driven on and off the ship on their own wheels or using a platform vehicle, such as a self-propelled modular transporter. This is in contrast to lift-on/lift-off (LoLo) vessels, which use a crane to load and unload cargo. RORO vessels have either built-in or shore-based ramps or ferry slips that allow the cargo to be efficiently rolled on and off the vessel when in port. While smaller ferries that operate across rivers and other short distances often have built-in ramps, the term RORO is generally reserved for large oceangoing vessels. The ramps and doors may be located in the stern, bow, or sides, or any combination thereof. Description Types of RORO vessels include ferries, cruiseferries, cargo ships, barges, and RoRo service for air deliveries. New automobiles that are transported by ...

Stabilizer (ship)
Ship stabilizers (or stabilisers) are fins or rotors mounted beneath the waterline and emerging laterally from the hull to reduce a ship's roll due to wind or waves. ''Active fins'' are controlled by a gyroscopic control system. When the gyroscope senses the ship roll, it changes the fins' angle of attack so that the forward motion of the ship exerts force to counteract the roll. ''Fixed fins'' and bilge keels do not move; they reduce roll by hydrodynamic drag exerted when the ship rolls. Stabilizers are mostly used on ocean-going ships. Function Fins work by producing lift or downforce when the vessel is in motion. The lift produced by the fins should work against the roll moment of the vessel. To accomplish this, two wings, each installed underwater on either side of the ship, are used. Stabilizers can be: *Retractable - All medium and large cruise and ferry ships have the ability to retract the fins into a space inside the hull in order to avoid extra fuel consumption and r ...

Rudder
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, aircraft, or other vehicle that moves through a fluid medium (generally aircraft, air or watercraft, water). On an aircraft the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane. A rudder operates by redirecting the fluid past the hull (watercraft), hull or fuselage, thus imparting a turning or yaw (rotation), yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or after end. Often rudders are shaped so as to minimize Drag (physics), hydrodynamic or aerodynamic drag. On simple watercraft, a tiller—essentially, a stick or pole acting as a lever arm—may be attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, cables, pushrods, or hydraulics may be used to link rudders to steering wheels. In typical air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helicopter Deck
A helicopter deck (or helo deck) is a helicopter pad on the deck of a ship, usually located on the stern and always clear of obstacles that would prove hazardous to a helicopter landing. In the United States Navy, it is commonly and properly referred to as the flight deck. In the UK's Fleet Air Arm, ''landing on'' is usually achieved by first lining up on the port quarter parallel to the ship's heading, then once the deck motion is deemed to be acceptable the pilot sidesteps the aircraft laterally using a white painted line (the bum line) as a reference. Shipboard landing for some helicopters is assisted though use of a haul-down device that involves attachment of a cable to a probe on the bottom of the aircraft prior to landing. Tension is maintained on the cable as the helicopter descends, assisting the pilot with accurate positioning of the aircraft on the deck; once on deck locking beams close on the probe, locking the aircraft to the flight deck. This device was pioneered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oerlikon 20 Mm Cannon
The Oerlikon 20 mm cannon is a series of autocannons, based on an original German Becker Type M2 20 mm cannon design that appeared very early in World War I. It was widely produced by Oerlikon Contraves and others, with various models employed by both Allied and Axis forces during World War II. Many versions of the cannon are still used today. Blowback-operated models History Origins During World War I, the German industrialist Reinhold Becker developed a 20 mm caliber cannon, known now as the 20 mm Becker using the advanced primer ignition blowback (API blowback) method of operation. This used a 20×70mmRB cartridge and had a cyclic rate of fire of 300 rpm. It was used on a limited scale as an aircraft gun on ''Luftstreitkräfte'' warplanes, and an anti-aircraft gun towards the end of that war. Because the Treaty of Versailles banned further production of such weapons in Germany, the patents and design works were transferred in 1919 to the Swiss firm SEMAG (''Seeba ...
