V14 Engine
A V14 engine is a V engine with 14 cylinders mounted on the crankcase in two banks of seven. It is a relatively rare layout, which is used on large medium-speed diesel engines used for power generation and marine propulsion. Marine use MAN B&W offers V14 layout for all its current medium-speed diesel engines except V28-33D and L58-64, with output ranging from .Medium Speed Engine Project Planning Guides MAN Diesel & Turbo.

V Engine
A V engine, sometimes called a Vee engine, is a common configuration for internal combustion engines. It consists of two cylinder banks—usually with the same number of cylinders in each bank—connected to a common crankshaft. These cylinder banks are arranged at an angle to each other, so that the banks form a "V" shape when viewed from the front of the engine. V engines typically have a shorter length than equivalent inline engines, however the trade-off is a larger width. V6, V8 and V12 engines are the most common layout for automobile engines with 6, 8 or 12 cylinders respectively. History The first V engine, a two-cylinder V-twin, was designed by Wilhelm Maybach and used in the 1889 Daimler Stahlradwagen automobile. The first V8 engine was produced in 1903, in the form of the Antoinette engine designed by Léon Levavasseur for racing boats and airplanes. The first V12 engine was produced the following year by Putney Motor Works in London, again for use in racing bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Straight-14 Engine
A straight-14 engine or inline-14 engine is a fourteen-cylinder piston engine with all fourteen cylinders mounted in a straight line along the crankcase. This design results in a very long engine, therefore it has only been used as marine propulsion engines in large ships. The only straight-14 engine known to reach production is part of the Wärtsilä-Sulzer RTA96-C family of 6-cylinder to 14-cylinder two-stroke marine engines. This engine is used in the Emma Mærsk, which was the world's largest container ship when it was built in 2006. The engine produces and displaces , has a bore of and a stroke A stroke is a medical condition in which poor blood flow to the brain causes cell death.

Royal Fleet Auxiliary
The Royal Fleet Auxiliary (RFA) is a naval auxiliary fleet owned by the UK's Ministry of Defence. It provides logistical and operational support to the Royal Navy and Royal Marines. The RFA ensures the Royal Navy is supplied and supported by providing fuel and stores through replenishment at sea, transporting Royal Marines and British Army personnel, providing medical care and transporting equipment and essentials around the world. In addition the RFA acts independently providing humanitarian aid, counter piracy and counter narcotic patrols together with assisting the Royal Navy in preventing conflict and securing international trade. They are a uniformed civilian branch of the Royal Navy staffed by British merchant sailors. RFA personnel are civilian employees of the Ministry of Defence and members of the Royal Naval Reserve and Sponsored Reserves. Although RFA personnel wear Merchant Navy rank insignia with naval uniforms, they are part of the Royal Navy. RFA vessels are ...

Leaf Class Tanker
The Leaf class is a class of support tanker of the British Royal Fleet Auxiliary (RFA). The class is somewhat unusual as it is an amalgam of various civilian tankers chartered for naval auxiliary use and as such has included many different designs of ship. Leaf names are traditional tanker names in the RFA, and are recycled when charters end and new vessels are acquired. Thus, there have been multiple uses of the same names, sometimes also sharing a common pennant number. The role of support tanker generally involves the bulk transport of fuel oils between distribution centres, the replenishment of front-line fleet tankers such as the and classes and using their replenishment at sea (RAS) abilities to allow them to directly support naval warships. For RAS, Leaf-class ships have an amidships derrick allowing a single vessel on either beam and a single point for a vessel astern.

RFA Bayleaf (A109)
RFA ''Bayleaf'' (A109) was a Leaf class tanker, Leaf-class support tanker of the Royal Fleet Auxiliary. Construction ''Bayleaf'' was one of four ships ordered from Cammell Laird at Birkenhead in 1973, and laid down in 1975 as the ''Hudson Sound''. When the ordering company ran into financial difficulties, the ships were laid up, and later were offered for sale or charter. The ship was finally launched on 27 October 1981, and when completed on 25 March 1982 she was then bareboat chartered to the Ministry of Defence (United Kingdom), Ministry of Defence (MoD) and renamed ''Bayleaf''. Service history She was almost immediately put into active service, and sailed to Gibraltar and Ascension Island en route for service in "Operation Corporate" – the Falklands War – in company with . She arrived in the Total Exclusion Zone on 9 June 1982, finally returning to Devonport on 31 August. In January 1991 she sailed from the UK to relieve during "Operation Granby" – the Fi ...

SA-15 (ship Type)
SA-15 is the project name for a series of icebreaking multipurpose cargo ships built in Finland for the Soviet Union in the 1980s. The ships, capable of independent operation in all prevailing arctic ice conditions, were the first merchant vessels designed for year-round operations in the Northern Sea Route. For this purpose they have hulls that resemble those of polar icebreakers and propulsion systems capable of withstanding ice loads. While the ships are also known as the ''Norilsk'' class after the first ship, ''Norilsk'', they are usually referred to by their project name which denotes a subarctic 15,000 DWT cargo ship.Kitagawa, H. et alNorthern Sea Route. Shortest Sea Route Linking East Asia and Europe. Ship & Ocean Foundation, 2001. . Nineteen SA-15 type ships were delivered by Finnish shipbuilders Wärtsilä and Valmet in 1982–1987, and two vessels remain in service.

Cylinder (engine)
In a reciprocating engine, the cylinder is the space in which a piston travels. The inner surface of the cylinder is formed from either a thin metallic liner (also called "sleeve") or a surface coating applied to the engine block. A piston is seated inside each cylinder by several metal piston rings, which also provide seals for compression and the lubricating oil. The piston rings do not actually touch the cylinder walls, instead they ride on a thin layer of lubricating oil. Steam engines The cylinder in a steam engine is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were cast in cast iron and later in steel. The cylinder casting can include other features such as valve ports and mounting feet. Internal combustion engines The cylinder is the space through which the piston travels, propelled to the energy generated from the combustion of the air/fuel mixture in the combustion chamber. In an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Norwegian Spirit
''Norwegian Spirit'' is a ''Leo''-class cruise ship operated by Norwegian Cruise Line (NCL). She was built in 1998 for Star Cruises as ''SuperStar Leo'' by the Meyer Werft shipyard in Papenburg, Germany. In 2004 she was transferred to NCL and renamed ''Norwegian Spirit.'' History The vessel was constructed by Meyer Werft in Papenburg, Germany. Named ''SuperStar Leo'' in 1998, the vessel was the first of Star Cruises ''Leo'' class.
