MOL Comfort
''MOL Comfort'' was a 2008-built Bahamian-flagged post-Panamax container ship chartered by Mitsui O.S.K. Lines. The vessel was launched in 2008 as ''APL Russia'' and sailed under that name until 2012, when the ship was renamed to ''MOL Comfort''. On 17 June 2013, she broke in two about off the coast of Yemen. The aft section sank on 27 June and the bow section, after having been destroyed by fire, on 11 July. General characteristics With an overall length of long, moulded beam of and fully laden draught of , ''MOL Comfort'' was too large to transit the Panama Canal and was thus referred to as a post-Panamax container ship. She measured 86,692 in gross tonnage and 48,825 in net tonnage, and had a deadweight tonnage of 90,613 tonnes. The container capacity of the ship, measured in twenty-foot equivalent units (TEU), was 8,110 of which 4,616 TEU is stored on the deck and 3,494 TEU in the holds. Like most large container ships, ''MOL Comfort'' was propelled by a single low- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Panama Canal
The Panama Canal ( es, Canal de Panamá, link=no) is an artificial waterway in Panama that connects the Atlantic Ocean with the Pacific Ocean and divides North and South America. The canal cuts across the Isthmus of Panama and is a conduit for maritime trade. One of the largest and most difficult engineering projects ever undertaken, the Panama Canal shortcut greatly reduces the time for ships to travel between the Atlantic and Pacific oceans, enabling them to avoid the lengthy, hazardous Cape Horn route around the southernmost tip of South America via the Drake Passage or Strait of Magellan and the even less popular route through the Arctic Archipelago and the Bering Strait. Colombia, France, and later the United States controlled the territory surrounding the canal during construction. France began work on the canal in 1881, but stopped because of lack of investors' confidence due to engineering problems and a high worker mortality rate. The United States took over the ...

Yield Strength
In materials science and engineering, the yield point is the point on a stress-strain curve that indicates the limit of elastic behavior and the beginning of plastic behavior. Below the yield point, a material will deform elastically and will return to its original shape when the applied stress is removed. Once the yield point is passed, some fraction of the deformation will be permanent and non-reversible and is known as plastic deformation. The yield strength or yield stress is a material property and is the stress corresponding to the yield point at which the material begins to deform plastically. The yield strength is often used to determine the maximum allowable load in a mechanical component, since it represents the upper limit to forces that can be applied without producing permanent deformation. In some materials, such as aluminium, there is a gradual onset of non-linear behavior, making the precise yield point difficult to determine. In such a case, the offset yiel ...

Nippon Kaiji Kyokai
is a ship classification society. It is also known by the brand name “ClassNK” or often in the industry as just “NK”. ClassNK is a non-profitable non-governmental organization dedicated to ensure the safety of life and property at sea, and the prevention of pollution of the marine environment. The principal work of the Society's expert technical staff is to undertake surveys to ensure that the rules which it has developed, are applied to both newly built and existing ships in order to ensuring the safety of these vessels. The rules cover not only hull structures, but also safety equipment, cargo handling gear, engines, machinery, and electrical and electronic systems among others. By the end of December 2007, the Society had 6793 ships totaling 152.22 million gross tons under class. This figure represents approximately 20 percent of the world merchant fleet currently under class. Although based in Japan, ClassNK has worldwide representation through a network of exclu ...

Sister Ship
A sister ship is a ship of the same class or of virtually identical design to another ship. Such vessels share a nearly identical hull and superstructure layout, similar size, and roughly comparable features and equipment. They often share a common naming theme, either being named after the same type of thing or person (places, constellations, heads of state) or with some kind of alliteration. Typically the ship class is named for the first ship of that class. Often, sisters become more differentiated during their service as their equipment (in the case of naval vessels, their armament) are separately altered. For instance, the U.S. warships , , , and are all sister ships, each being an . Perhaps the most famous sister ships were the White Star Line's s, consisting of , and . As with some other liners, the sisters worked as running mates. Other sister ships include the Royal Caribbean International's and . ''Half-sister'' refers to a ship of the same class but with some s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coaming
Coaming is any vertical surface on a ship designed to deflect or prevent entry of water. It usually consists of a raised section of deck plating around an opening, such as a cargo hatch. Coamings also provide a frame onto which to fit a hatch cover. The protective metal sheeting or plating protecting against water entry into ventilation shafts in large ships is called a coaming as it suits this purpose. The term was borrowed by the aviation industry to refer to a low rim around the opening for an unenclosed cockpit. The origin of the term is unknown. ''Coaming'' also refers to the raised structure around the cockpit of a kayak A kayak is a small, narrow watercraft which is typically propelled by means of a double-bladed paddle. The word kayak originates from the Greenlandic word ''qajaq'' (). The traditional kayak has a covered deck and one or more cockpits, each se ....

Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crosshead
In mechanical engineering, a crosshead is a mechanical joint used as part of the slider-crank linkages of long reciprocating engines (either internal combustion or steam) and reciprocating compressors to eliminate sideways force on the piston. Also, the crosshead enables the connecting rod to freely move outside the cylinder. Because of the very small bore-to-stroke ratio on such engines, the connecting rod would hit the cylinder walls and block the engine from rotating if the piston was attached directly to the connecting rod like on trunk engines. Therefore, the longitudinal dimension of the crosshead must be matched to the stroke of the engine. Overview On smaller engines, the connecting rod links the piston and the crankshaft directly, but this transmits sideways forces to the piston, since the crankpin (and thus the direction the force is applied) moves from side to side with the rotary motion of the crank. These transverse forces are tolerable in a smaller engine. A large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cargo Hold
120px, View of the hold of a container ship A ship's hold or cargo hold is a space for carrying cargo in the ship's compartment. Description Cargo in holds may be either packaged in crates, bales, etc., or unpackaged (bulk cargo). Access to holds is by a large hatch at the top. Ships have had holds for centuries; an alternative way to carry cargo is in standardized shipping containers, which may be loaded into appropriate holds or carried on deck. Holds in older ships were below the orlop deck, the lower part of the interior of a ship's hull, especially when considered as storage space, as for cargo. In later merchant vessels it extended up through the decks to the underside of the weather deck. Some ships have built in cranes and can load and unload their own cargo. Other ships must have dock side cranes or gantry cranes to load and unload. Cargo hatch A cargo hatch or deck hatch or hatchway is type of door used on ships and boats to cover the opening to the cargo hold o ...

Twenty-foot Equivalent Unit
The twenty-foot equivalent unit (abbreviated TEU or teu) is an inexact unit of cargo capacity, often used for container ships and container ports.Rowlett, 2004. It is based on the volume of a intermodal container, a standard-sized metal box which can be easily transferred between different modes of transportation, such as ships, trains, and trucks. The container is defined by its length, although the height is not standardized and ranges between and , with the most common height being . It is common to designate a container as 2 TEU, rather than 2.25 TEU. Forty-foot equivalent unit The standard intermodal container is designated as twenty feet long (6.1m) and wide. Additionally there is a standard container with the same width but a doubled length of forty feet called a 40-foot (12.2m) container, which equals one forty-foot equivalent unit (often FEU or feu) in cargo transportation (considered to be two TEU, see below). In order to allow stacking of these types a forty-fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deadweight Tonnage
Deadweight tonnage (also known as deadweight; abbreviated to DWT, D.W.T., d.w.t., or dwt) or tons deadweight (DWT) is a measure of how much weight a ship can carry. It is the sum of the weights of cargo, fuel, fresh water, ballast water, provisions, passengers, and crew. DWT is often used to specify a ship's maximum permissible deadweight (i.e. when it is fully loaded so that its Plimsoll line is at water level), although it may also denote the actual DWT of a ship not loaded to capacity. Definition Deadweight tonnage is a measure of a vessel's weight carrying capacity, not including the empty weight of the ship. It is distinct from the displacement (weight of water displaced), which includes the ship's own weight, or the volumetric measures of gross tonnage or net tonnage (and the legacy measures gross register tonnage and net register tonnage). Deadweight tonnage was historically expressed in long tonsOne long ton (LT) is but is now usually given internationally in t ...
