Hawaii Superferry
Hawaii Superferry was a Hawaii-based transportation company that provided passenger and vehicle transportation between Honolulu Harbor on the island of Oahu and Kahului Harbor on Maui. Legal issues over environmental impact statements and protests from residents of Maui and Kauai temporarily delayed the implementation of service, but service between Oahu and Maui began in December 2007. The company had hoped to return service to Nawiliwili Harbor on Kauai and additionally planned to eventually provide service to Kawaihae Harbor on the Big Island. Ferry operations were suspended in March, 2009 after the Hawaii Supreme Court ruled that a state law allowing the Superferry to operate without a second complete environmental impact statement was unconstitutional. The company went bankrupt as a result of these actions preventing service in Hawaii. On July 2, 2009 a Delaware Bankruptcy Court granted the company's motion to abandon both the ships ''Alakai'' and ''Huakai'', ending all ...

KGMB
KGMB (channel 5) is a television station in Honolulu, Hawaii, United States, serving the Hawaiian Islands as an affiliate of CBS. It is owned by Gray Television alongside NBC affiliate KHNL (channel 13) and Kailua-Kona–licensed Telemundo affiliate KFVE (channel 6). The stations share studios on Waiakamilo Road in Honolulu's Kapālama neighborhood, while KGMB's transmitter is located in Akupu, Hawaii. History The station first signed on the air on December 1, 1952, as the first television station in Hawaii. KGMB-TV was originally owned by J. Howard Worrall along with KGMB radio (AM 590, now KSSK) and operated from studios on Kapiolani Boulevard in Honolulu. The station carried programming from three of the four major networks at the time (excluding DuMont), but was a primary CBS affiliate owing to KGMB-AM's long affiliation with CBS Radio. The station lost NBC programming when KONA-TV (channel 2, now KHON-TV) signed on two weeks later, and lost ABC when KULA-TV (channel 4, no ...

Marine Propulsion
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] |
Pump-jet
A pump-jet, hydrojet, or water jet is a marine system that produces a jet of water for propulsion. The mechanical arrangement may be a ducted propeller (axial-flow pump), a centrifugal pump, or a mixed flow pump which is a combination of both centrifugal and axial designs. The design also incorporates an intake to provide water to the pump and a nozzle to direct the flow of water out of the pump.http://www.hamiltonmarine.co.nz/includes/files_cms/file/JetTorque%2008.pdf Design A pump-jet works by having an intake (usually at the bottom of the hull) that allows water to pass underneath the vessel into the engines. Water enters the pump through this inlet. The pump can be of a centrifugal design for high speeds, or an axial flow pump for low to medium speeds. The water pressure inside the inlet is increased by the pump and forced backwards through a nozzle. With the use of a ''reversing bucket'', reverse thrust can also be achieved for faring backwards, quickly and withou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ultra-low Sulfur Diesel
Ultra-low-sulfur diesel (ULSD) is diesel fuel with substantially lowered sulfur content. Since 2006, almost all of the petroleum-based diesel fuel available in Europe and North America has been of a ULSD type. The move to lower sulfur content allows for the application of advanced emissions control technologies that substantially lower the harmful emissions from diesel combustion. Testing by engine manufacturers and regulatory bodies have found the use of emissions control devices in conjunction with ULSD can reduce the exhaust output of ozone precursors and particulate matter to near-zero levels. In 1993 the European Union began mandating the reduction of diesel sulfur content and implementing modern ULSD specifications in 1999. The United States started phasing in ULSD requirements for highway vehicles in 2006, with implementation for off-highway applications, such as locomotive and marine fuel, beginning in 2007. Lubricity Sulfur is not a lubricant in and of itself, but it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MTU Friedrichshafen
MTU Friedrichshafen GmbH is a German manufacturer of commercial internal combustion engines founded by Wilhelm Maybach and his son Karl Maybach in 1909. Wilhelm Maybach was the technical director of Daimler-Motoren-Gesellschaft (DMG), a predecessor company of the German multinational automotive corporation Daimler AG, until he left in 1907. On 23 March 1909, he founded the new company, Luftfahrzeug-Motorenbau GmbH (Aircraft Engine Manufacturing Corp), with his son Karl Maybach as director. A few years later the company was renamed to Maybach-Motorenbau GmbH (Maybach Engine Manufacturing Corp), which originally developed and manufactured diesel and petrol engines for Zeppelins, and then railcars. The Maybach Mb.IVa was used in aircraft and airships of World War I. The company first built an experimental car in 1919, with the first production model introduced two years later at the Berlin Motor Show. Between 1921 and 1940, the company produced various classic opulent vehicles. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Merchant Marine Act Of 1920
The Merchant Marine Act of 1920 is a United States federal statute that provides for the promotion and maintenance of the American merchant marine. Among other purposes, the law regulates maritime commerce in U.S. waters and between U.S. ports. Section 27 of the Merchant Marine Act is known as the Jones Act and deals with cabotage (coastwise trade). It requires that all goods transported by water between U.S. ports be carried on ships that have been constructed in the United States and that fly the U.S. flag, are owned by U.S. citizens, and are crewed by U.S. citizens and U.S. permanent residents.46. U.S.C. § 50101 et seq. (2006).Lin, Tom C.W.Americans, Almost and Forgotten 107 California Law Review (2019) The act was introduced by Senator Wesley Jones. The law also defines certain seaman's rights. Laws similar to the Jones Act date to the early days of the United States. In the First Congress, on September 1, 1789, Congress enacted Chapter XI, "An Act for Registering and C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-speed Craft
A high-speed craft (HSC) is a high-speed water vessel for civilian use, also called a fastcraft or fast ferry. The first high-speed craft were often hydrofoils or hovercraft, but in the 1990s catamaran and monohull designs become more popular and large hydrofoils and hovercraft are no longer built. Most high-speed craft serve as passenger ferries, but the largest catamarans and monohulls also carry cars, buses, large trucks and freight. In the 1990s there were a variety of builders, but due to HSC high fuel consumption, many shipbuilders have withdrawn from this market so the construction of the largest fast ferries, up to 127 metres, has been consolidated to two Australian companies, Austal of Perth and Incat of Hobart. There is still a wide variety of builders for smaller fast catamaran ferries between 24 and 60 metres. Hulled designs are often powered by pump-jets coupled to medium-speed diesel engines. Hovercraft are usually powered by gas turbines or diesel engines dri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Catamaran
A Formula 16 beachable catamaran Powered catamaran passenger ferry at Salem, Massachusetts, United States A catamaran () (informally, a "cat") is a multi-hulled watercraft featuring two parallel hulls of equal size. It is a geometry-stabilized craft, deriving its stability from its wide beam, rather than from a ballasted keel as with a monohull boat. Catamarans typically have less hull volume, smaller displacement, and shallower draft (draught) than monohulls of comparable length. The two hulls combined also often have a smaller hydrodynamic resistance than comparable monohulls, requiring less propulsive power from either sails or motors. The catamaran's wider stance on the water can reduce both heeling and wave-induced motion, as compared with a monohull, and can give reduced wakes. Catamarans were invented by the Austronesian peoples which enabled their expansion to the islands of the Indian and Pacific Oceans. Catamarans range in size from small sailing or rowing ve ...
