The largest cargo ship in the world: Emma? Maersk?
According to the British Daily Express, Daily Mail and Daily Mirror, the container ship 65438+1October 3 1? Emma. Maersk? It is the largest super cargo ship in the world and can carry 1 1000 huge metal containers.
A few days ago? Emma. Maersk? It is sailing from China to England, full of goods to celebrate Christmas for Europeans, and will arrive in Felixstowe, England this Saturday. Gundam 12 floor office building, it is reported that the world's largest container ship? Emma. Maersk? Made in Denmark, it belongs to the famous Maersk shipping company in Denmark. It sailed from Aarhus Port in early September, arrived in Singapore on June 10, and then arrived in China, Shenzhen and Hongkong. Emma. Maersk? After loading goods in Asia, it is now crossing the Mediterranean and heading for Britain. It will arrive in Felixstowe, England this Saturday.
It is reported that? Emma. Maersk? It is 397 meters long, which is longer than the Parliament Building in London, England. It is 56 meters wide and is not suitable for crossing the Panama Canal. When full of goods, it is more than 60 meters high, which is similar to the office building with 12 floor. ? Emma. Maersk? The weight of the anchor chain is equivalent to the weight of five adult African elephants, and its engine can produce the sum of horsepower equivalent to 1 156 family cars; The propeller of the ship weighs 130 tons, which is equivalent to the weight of 20 African elephants. There are more than 10000 containers? Emma. Maersk? There are 1 1000 metal containers, each as big as a freight truck. Because it carried all the imported goods from the British and Europeans for Christmas on its maiden voyage, this ship? Super freighter? Dubbed by the British as? Christmas number? .
It is reported that? Emma. Maersk? The cargo on board includes 5 tons of Christmas cookies, 17 container toys, a container of digital cameras, 1236 small box calendars, 10800 men's shirts, a container of cosmetics, 650,000 plastic bags, 12 tons of kitchen utensils, and 1886 thousand pieces. When is this ship? Super freighter? After arriving at the British port this Saturday, all containers will be unloaded by modern equipment for even less than one day. British Maritime Union? The British Nautilus? Expert Andrew? Lin Ning said: In the 1970s, after an ordinary container ship docked, it would take you 150 hours to unload all the goods. ? What if it will? Emma. Maersk? All the containers in the world are lined up one after another, which can be 45 miles long. Thousands of British trucks will be on standby to transport these Christmas goods from China to shops all over the UK. ? Emma. Maersk? After unloading the goods in the UK, it will continue to travel to China, Hongkong and Japan via Europe and Singapore.
It is reported that 1966 before the first world voyage of the container ship, Emma? Maersk? These goods in the world need 40 cargo ships to be transported to Britain, and each cargo ship needs 30 crew members. But? Emma. Maersk? On the super container freighter, only 13 crew members are needed. ? Emma. Maersk? It is the largest container ship in the world, but it? The largest cargo ship in the world? Its title may not last long because its 1 1 sister ship is under construction. In addition, it is reported that Japan and South Korea are also building larger cargo ships. Ships to be built in the future can carry 65,438+08,000 metal containers. Will such a ship really become? Floating city? Because it can supply anything to the whole world.
Emma. The specific introduction of Maersk
Emma, who was baptized in the water on August 12, 2006 and made her maiden voyage on September 8 of the same year? Maersk is Arnold, former president of Fast Mast Group. Maersk? Mckinney? Muller (Arnold m? Kinney m? Ller) has inherited the title of the world's largest container ship since it was launched. In addition, due to the world's number one supertanker Nock? Knock Nevis (458 meters long) was scrapped and dismantled in India in 20 10, and Emma with a length of 397 meters was made. Maersk also holds the title of the longest ship still sailing.
Emma. Maersk has a displacement of170,974 tons and a cargo capacity of 1 1 0,000 TEUs. It mainly travels in Aarhus, Denmark. On the Eurasian route between rhus and East Asia, its frequent ports of call include bremerhaven in Europe, Rotterdam in Asia, Shenzhen and Hongkong, so it is also one of the frequent visitors crossing the Suez Canal.
Main structure and composition of cargo ship
Although there are many kinds of modern transport ships with different structures, they are all composed of hull (including superstructure) and power plant (see ship power plant), and are equipped with various outfitting equipment and systems.
Hull and its superstructure are the main parts of transport ships, providing loading space for passengers, crew, goods, power plants, oil, water and other substances.
The hull of steel carrier is welded by various specifications of steel plates and profiles, and it is a watertight hollow structure consisting of bottom, two sides, head end, tail end and deck. The bottom of the ship has single and double bottom structures, which are composed of outer bottom plate (including flat keel), inner bottom plate and inner bottom plate (ship with double bottom structure), longitudinal skeleton, transverse skeleton and other components. There are two kinds of ship bottom skeletons: transverse skeleton and longitudinal skeleton. The transverse skeleton structure consists of ribs (transverse members), middle longitudinal beams (longitudinal beams located at the longitudinal center line of the bottom of the ship, also called middle inner keel), side longitudinal beams (longitudinal beams located at both sides of the longitudinal center line of the bottom of the ship, also called side inner keel) and other components; The longitudinal skeleton structure reduces the number of ribs, but increases the longitudinal bone at the bottom. Both sides are composed of watertight outboard plates and skeletons (ribs, side longitudinal beams, longitudinal bones, etc.). ) to strengthen them. In order to strengthen the fore and aft structure of the hull, there is a head column at the head end and a tail column at the tail end. If the main road bulkhead is arranged inside the hull, cabins with different uses will be formed. Anti-collision bulkheads are arranged at the bow and stern of the ship to form a front peak cabin and a rear peak cabin respectively to ensure safety. The engine room where the main engine, auxiliary engine and auxiliary equipment are installed is generally located in the middle or stern of the ship, and the corresponding ship type is called medium or stern type. In the vertical direction, the hull is separated by deck and platform, and there is at least one deck, such as oil tankers and bulk carriers; More than ten floors, such as ocean liner. The top watertight deck that runs through the fore and aft is called the upper deck. The strength of the hull must be able to withstand the load on board, external water pressure and bending and torsion stress caused by wind and waves.
Superstructure refers to the building above the upper deck. The superstructure of the cargo ship is mainly used for driving manipulation and crew life. In the past, typical general cargo ships were mostly medium-sized ships, and their superstructures were located at the bow, stern and middle of the ship, which were called the first floor, the stern building and the bridge building respectively. This kind of ship is called Mishima Ship. Bridge building is the center of the whole ship's work and life. The top floor is the bridge, chart room, telegraph room, etc. The part under the bridge is the place where the crew live, rest and entertain. In order to get more use and living space, the third floor can be connected separately or completely. If the first building is connected with the bridge building, the first construction ship will grow; Connecting the poop with the bridge is to make the poop bigger. At the beginning of the 20th century, in order to expand the loading capacity of the ship, the shipowner built a sheltered deck ship with two decks, taking advantage of some weaknesses in the tonnage measurement regulations at that time. The space between the two decks can be loaded, not included in the gross tonnage, reducing various service fees and taxes, so it has long been the main ship type of dry cargo ships. However, this type of ship is not watertight and safe, so the International Maritime Organization revised the survey rules and cancelled this type of ship. Modern cargo ships are mostly stern-type, and the superstructure is also located at the stern. The superstructure of passenger ships is more developed than that of cargo ships, and there are more decks. The interior of each deck is separated by steel walls, which becomes a place for passengers to live and carry out various activities.
The power plant includes the main engine that provides propulsion power for the ship, the generator set that provides electricity and lighting for the whole ship, and various other auxiliary machines and equipment. The mainframe is the heart of the transport ship. The main engines of modern transport ships are mostly low-speed or medium-speed diesel engines, which drive the propeller installed at the tail directly or after deceleration to push the ship forward. In addition to diesel engines, a few ships also use steam engines, steam turbines, gas turbines and even nuclear power plants. There are 2~3 diesel generator sets on board, generally using 400 V three-phase alternating current with frequency of 50 Hz or 60 Hz. The ship is also equipped with auxiliary boilers or waste gas boilers to provide steam and heat source for the whole ship. Various auxiliary machines and equipment mainly include air compressors, various oil pumps, water pumps, heat exchangers, pipelines and oil tanks.
Outfitting equipment and outfitting equipment of each system include: ① control equipment, such as rudder equipment; (2) Mooring equipment, such as mooring equipment and mooring equipment; ③ Close the equipment, such as hatch cover, watertight door, side door and entrance cover. (4) Signal equipment such as signal lights and signal flags. ⑤ Life-saving equipment, such as lifeboats, life rafts, lifebuoys and life jackets; ⑥ Cargo lifting equipment, such as derrick device and deck crane on cargo ship (see cargo lifting equipment), cargo oil pump on oil tanker, elevator and springboard on ro-ro ship, etc. ⑦ Other equipment, such as anti-sway equipment on passenger ships, towing equipment on tugboats, and pushing devices on pusher ships. The ship's various systems include: bilge water drainage system for draining the accumulated water in the bilge, ballast water system for supplying water to and draining water from the ballast water tank, fire fighting system for supplying water to extinguish fire, drainage, treatment and sewage drainage system for removing accumulated water on deck, fecal water and washing sewage, domestic water system for supplying drinking water, washing water and sanitary water to crew and passengers, and ventilation, heating and air conditioning system.
