AdmiralHood>> Yes, when so much water is poured in that the weight of the ship along with the water inside reaches the weight of the water in the entire volume of the ship, including masts and superstructures, the ship will sink. But if the mast sticks out on the surface, and water no longer flows inside (everything that could have been flooded has already been flooded), then the ship will remain floating like a submarine with a periscope, hey.
IGOR_MORE> A little wrong. The meaning of the action of submarine ballast tanks: by regulating the flooding of the volume, a certain overall density of the body is achieved. In other words (banally), the volumes of metal, air and other contents of the ship + the weight of the collected water are summed up. If this average density is less than the density of water, the submarine will float; if not, it will sink.
IGOR_MORE> The essence of the Capt(N) question can be illustrated by examples from practice, when torpedoed ships did not want to sink because of the cargo they were carrying. It would seem that the ship is loaded to its maximum capacity, but this heaviness not only does not sink it, but even keeps it afloat. This is where the ballast principle comes into play: by filling the volume, making the object heavier. Well, when there is solid forest in the holds, for example, no matter how much it is wet, the water will not immediately reduce the real density of the cargo, which means it will not fill the ship’s compartments to the level at which the ship with its volumes will assume an overall negative density and, accordingly, buoyancy. ..
I read your remark for a long time and carefully, but I still didn’t understand how it contradicts my remark.
As for the fact that a ship filled with light cargo is unsinkable, this is not always correct. If all the voids in the vessel are filled with water, then there will be a competition - who will win. Either the iron from which the ship is made will drag it to the bottom, or a light weight with positive buoyancy will keep it on the surface.
Example. A vessel with a displacement without cargo of 10,000 tons. Made of steel with a density of 7.8. Underwater with the compartments filled with water it will weigh
10,000*(7.8-1)/7.8 = 8700 tons. Let’s load timber with a density of 0.8 into the compartments. Every 800 kg of timber will create 200 kg of positive buoyancy. Therefore, to ensure that the ship does not sink under any circumstances, 8700 * 800/200 = 34,800 tons of timber must be shoved into it.
If the timber is 34,799 tons, then if the compartments are completely flooded, the ship will still sink.
Of course, it is unrealistic to flood all the compartments even if hit by several torpedoes, so a ship with a light cargo always has a better chance of staying afloat than a ship loaded with cast iron ingots :=)
P.S. By the way, it is almost impossible to fill the tanks of a submarine with water so that the buoyancy is exactly zero. Therefore, the vertical rudders actually hold the boat at the required depth. In the absence of movement, the boat can remain at a fixed depth for a long time only if it lies on the bottom.
Shipbuilding began to develop in ancient times. From century to century, only the shape and size of the ships changed. But now the most big ships in the world they never cease to amaze people in modern ports.
Immigrants from the Scandinavian peninsula, the Vikings, almost always roamed the seas. Their descendants are still considered leaders in shipbuilding.
Norway, tanker Knock Nevis, length 458 meters
Norwegian tanker Knock Nevis has a length of 458.45 meters, a beam of 69 meters, and a loaded draft of 24.61 meters. Its dimensions allow it to be called the largest water vessel in the world. Its deadweight is 564,763 tons (4.1 million barrels of oil), and the maximum speed that the tanker can reach is 13 knots. braking distances 10.2 kilometers. It was built in 1979 in Yokosuka, Japan, by order of a shipowner from Greece. The next owner decided to enlarge the vessel. As a result, it was cut and extended, and additional sections were added to the body.
Initially, the tanker operated between the United States and the Middle East. But in 1986, it began to be used as a floating terminal for reloading and storing oil during the Iraq-Iran war. In 1988, Knock Nevis was heavily damaged after being attacked by Iraqi aircraft.

After the war, the ship found shelter in Brunei and flew the Norwegian flag. After repairs, the tanker changed its name twice: Happy Giant and Jahre Viking.
After the passage of a law in Europe and the United States banning the use of single-walled tankers (the Knock Nevis is only 3.5 centimeters thick), the vessel was rebuilt into a “floating storage unit.” And then they returned his original name. Now the tanker has washed up on the Indian coast and is awaiting disposal.
Denmark, container ship Emma Maersk, length 396.8 meters
The Danish container ship Emma Maersk has a length of 396.84 meters and a beam of 63.1 meters. Now the ship is called the world's largest container ship (it can transport up to 11 thousand containers at a time). Emma Maersk was built in 2006; the owner of the shipbuilding company, Arnold Maersk, named it in honor of his deceased wife. Later, seven more similar ships were built.
Emma Maersk can reach speeds of up to 31 knots. And it travels about 170 thousand nautical miles per year (7.5 distances around the planet), sailing between Europe and the Far East through the Suez Canal (the Panama Canal is closed for such a large ship).

A 20-krona coin was dedicated to the container ship in Denmark.
Bahamas, cruise ship Oasisoftheseas, length 360 m
First Oasis cruise ship sails Bahamas. At the time of construction it became the largest passenger airliner in the world. It was replaced only by a ship of this class, Allure of the Seas, which is 5 centimeters larger. Oasisoftheseas weighs 45 thousand tons, consists of 48 thousand parts, its length is 360 meters (by the way, the famous Titanic was 269 meters long, 53 meters high), maximum speed is 24 knots.
Allure of the Seas was built by a Finnish shipyard commissioned by an American shipping company. The contract for the construction of the first vessel was signed at the beginning of 2006. Initially, the project was called Project Genesis, about modern name became known only in 2008.
The ship was laid down on June 19, 2007, a little over a year later the construction dock was flooded, but additional equipment did not stop. Tests began in June 2009 in the Baltic and ended a couple of weeks later. In October 2009, Allure of the Seas set sail for its home port in Fort Lauderdale. While traveling along Baltic Sea, he barely passed through the Great Belt Bridge (passage is allowed for ships up to 65 meters). To do this, we had to retract the exhaust pipes and increase the speed to maximum in order to increase the stern draft while moving. As a result, there was still about half a meter left from the ship to the bridge.
The cruise ship was christened on November 30, 2009 at its home port, and it departed on its first voyage on December 5. At the same time, the cruise announced calls at the ports of Sint Maarten, the Bahamas and St. Thomas. Only they could accept such a large ship.
A real seaside hotel
By the way, on such a huge ship you can live like on land. There is an ice skating rink, a casino, a theater, night club, disco, jazz club, carousel pools, water park, shops and boutiques, restaurants and bars, sports clubs with basketball and volleyball courts and even a golf course. And that is not all. Passengers can relax in the shade of trees (there are about 12 thousand of them).
Great Britain, liner Queen Mary 2, length 345 meters
One of the world's largest passenger ships was put into operation in early 2004. It was launched in France at the Saint-Nazaire shipyards. Queen Mary 2 is 76 meters longer than the Titanic.
The liner was named after Queen Mary, which, at one time, was named after the wife of King George V of Britain, Mary of Teck.
The Queen Mary was built at the Chantiers de l’Atlantique shipyard in Saint-Nazéren. The Ile de France, Normandie and France were assembled there.
The liner set off on its first voyage on January 10, 2007 from the American Fort Lauderdale and finished there 81 days later. This trip is recorded in the Guinness Book of Records as the largest passenger ship around the world. There were almost half a thousand people on board; some paid an additional $100,000 to their ticket for the round-the-world trip.
Interestingly, while passing through New York, passengers on the upper deck can look the Statue of Liberty straight in the eyes.
On board this ship there is everything you need for an idle life. 1310 cabins, 4 swimming pools, the largest library at sea (800 thousand books), a helicopter pad, an Internet cafe, 6 restaurants, 12 galleys, laundries, a tennis court, a mini golf course, the only planetarium at sea, a theater, 2 cinemas, and Also shopping mall, casino, sports club and even a ballroom.
USA, aircraft carrier USS Enterprise (CVN-65), length 342 meters
This is the first nuclear-powered aircraft carrier power plant. It was laid down at the end of 1957 and put into operation in 1961.
The largest warship in the world is 342.3 meters long. Nuclear fuel from one load is enough for 13 years of operation, and during this time the aircraft carrier is capable of traveling about 1 million miles.
The final cost of the aircraft carrier reached $451 million. And it was precisely because of such a high price that serial construction never began, although initially it was planned to assemble 5 more Enterprise brothers.
At the beginning of 1962, the aircraft carrier made its maiden voyage. It was then commanded by Vincent DePauw.
The first “Baptism of Fire” occurred during the Cuban Missile Crisis. The ship became part of the US Second Fleet and participated in the naval blockade of Cuba. Then he served for several years in the Mediterranean Sea. In 1964, Enterprise made trip around the world consisting of three nuclear-powered ships.
In 1965, the ship became part of the Seventh Fleet and sailed to Southeast Asia. It became the first ship with a nuclear control system to take part in combat operations (the Vietnam War). The aircraft carrier set a record - exactly 165 combat sorties per day.
On January 14, 1969, one of the rockets self-launched on board. It hit the fuel tank, which spilled, followed by explosions of aerial bombs and random scattering of missiles. As a result, 27 people were killed, 343 were injured, and 15 aircraft were destroyed. Damage was estimated at $6.4 million. In the early 1980s, Enterprise experienced the removal of the SCANFAR radar and a major reactor overhaul. The aircraft carrier was decommissioned on December 1, 2012.

People are always interested in what is superior to other similar objects in their strength, size, qualities, etc. This is why it exists, to celebrate the most outstanding objects, phenomena, people, etc.
1. To date, Knock Nevis is the most big ship in the world.
This tanker is designed to transport fuel.
Its length is almost 459 m and its width is 24 m.
The vessel's displacement is 565 thousand tons.
The ship was originally built for a Greek customer. But he didn't receive it.
After that, it was bought at auction by a Hong Kong company.
But in 1991 it was sold again; the new owner purchased it for $39 million.
This supertanker is included in the Guinness Book of Records.
With its impressive parameters, the vessel looks really powerful, and it is also painted in a spectacular red color. 
2. The biggest cruise ship- considered “Allure of the Seas” (charm of the seas).
It was put into operation in 2010 and is still in operation today.
The average cost of such airliners is from 500 to 800 million dollars
Its dimensions: length - 362 m, width - 66 m, height - 72 m. displacement - 225 thousand tons.
The liner has 17 decks, about 2,700 cabins, which can accommodate about 6,400 passengers.
By the way, he has a twin brother “Oasis”, who is only 5 cm smaller than him, but in terms of characteristics they are the same.
It is a city in the middle of the ocean with everything you need for a great luxury vacation.
There are boutiques, restaurants, theaters, swimming pools (see:), cinemas and solariums.
There are VIP cabins here, total area which range from 50 to 150 sq. m.
3. This is not the best big airliner, but unlike the previous ones, it is very famous - “Queen Mary 2”.
It was built in France in 2003 and at that time was the largest cruise ship in the world, the dimensions of which are as follows: length - 345 meters, width - 41, height - 71 m. Capacity 2600 people
The ship also has all kinds of recreational facilities, personal care, shops, a library, a ballroom, a planetarium, 4, etc.
The ship was named after the liner "Queen Mary", which received its name in honor of the wife of the English King George 5 - Mary of Teck.
"Queen Mary" became the most big liner who traveled around the world.
This happened in 2007. The cruise, which started and ended in the port of Fort Lauderdale (Florida), lasted 81 days.
Size comparison with: man, bus, plane and Titanic. 
4. Disney Dream Cruise Ship , the length of which is 340 m. Capacity 3950 people
5. — length 333 meters.
6. Norwegian Epic — length 325.5 meters
7. - length 317 m.
8. — 311 m. Capacity about 3500 passengers
9. — 306 meters
10. Princess Diamond — 290 m. Passenger capacity 2600 people
These were the largest ships in the world, which are beautiful not only from the outside, but also from the inside.
But time will tell what kind of ships will be sailing the seas and oceans in 10-20 years.
Once upon a time the largest ship was the Titanic. But today there are ships that are several times the size of the Titanic. In this article we will talk about the largest ship in the world.
Titanic was a cruise ship. Everyone remembers his story. He collided with an iceberg because he was very huge and could not turn sideways in time. It seemed that such liners would not be able to exist; they were very bulky and their fate was not comforting. But it turned out that similar liners can exist, and at the same time be several times larger. Today, the largest ship is the Oasis of the Seas. Photo below:
It really is several times larger than the Titanic. Look at this image:
Company " Royal Caribbean International wanted to build a ship that would be the best for many years to come and on October 28, 2009, Oasis of the Seas was launched. It immediately became the largest cruise ship in the world. The ship also became the most expensive, as its price was $1.24 billion. The average cost of a ship staying in the port is $230,000. And this is within just a few hours of stay!
The dimensions of the liner are amazing: its length is 360 meters, its width is 66 meters, and its height is at its most high point was 72 meters.
The largest ship: characteristics
They say correctly that this is not just a ship, but a whole Small town. The dimensions of this liner are five times larger than the dimensions of the Titanic. There can be 6,360 passengers and 2,160 crew on board. On the ship a large number of various entertainment centers. Starting from swimming pools to a real theater. The ship has 4 swimming pools, which together make up 23,000 liters of water. There are 12 thousand plants and 56 large trees on the ship. There is a park, a climbing wall, 10 spa cents. It is so huge that it is even divided into themed areas.
The largest ship has several restaurants, its park is similar to the park in New York, so classical American music will be performed there. There is a lot more that can be said about the ship.
Dockwise Vanguard
Of course, Oasis of the Seas is the largest ship, but there is also the Dockwise Vanguard, the world's largest heavy cargo ship.
On February 12, 2013, the ship made its first voyage. Dockwise Vanguard arrived in the Gulf of Mexico in April 2013. The cargo it carried was 56,000 tons, but the maximum load could be 110,000 tons.
The vessel was built by Hyundai Heavy Industries for Dockwise Shipping. It was launched in 2012. In terms of characteristics, it does not surpass the Oasis of the Seas liner. Displacement 91,238 tons, deadweight 117,000 tons. Length 275 meters, width 79 meters, draft 9.5 meters. Maximum speed 14.4 knots, average 12.9 knots.
The method of loading onto the ship is also unique. Special compartments are filled with water and the ship slowly but surely sinks under water. Once the ship is underwater, cargo is loaded onto it.
To maintain the ship, 60 people will be required, who are located in the hold of the ship.
The well-known Costa Concordia, which was wrecked in January 2012 off the coast of the island of Giglia (Tuscany), will be transported using this ship. Let me remind you that the Costa Concordia is several times larger than the Titanic.
The largest ships in the world
§ 7. Vessel weight and volume meters
Each vessel, as a physical body, has a certain weight and volume. Floating on the water, it occupies a position determined by its draft, which is directly related to its weight and the volume of the underwater part. These dependencies are expressed by numerical characteristics, which are divided according to dimension into linear (already familiar to us), weight and volume meters of the vessel.Weight displacement is the main weight meter of the vessel and is composed of load items from permanent weight a (weight of the housing, mechanisms, electrical equipment, devices, etc.) and variable weight (fuel, supplies, crew, transported cargo, passengers, etc.). The weight of these cargoes is accurately taken into account when designing the ship in a special document called vessel weight load and in accordance with which all calculations related to determining the qualities of the vessel are made.
Depending on the amount of variable cargo received, the weight displacement can vary widely, as a result of which there is a need to establish the types of displacement of the vessel under different states of its load. For civil courts The following main types of displacement are established:
1) light displacement, equal to the constant weight of the vessel, with water in boilers, mechanisms and pipelines, with inventory, permanent spare parts and supplies, but without cargo, passengers, crew and without fuel;
2) fully loaded displacement, equal to the lightship displacement plus the transported cargo, crew, fuel and all supplies at the deepest permissible draft. The following types of displacement are established for military surface ships:
1) light displacement, equal to the weight of a ship ready for action, but without personnel, ammunition, supplies, food and without reserves of fuel, lubricants and fresh water;
2) standard displacement, equal to the weight of a ship ready for action with personnel and all supplies necessary in war time, but without reserves of fuel, lubricants and boiler water;
3) normal displacement, equal to the standard plus 50% of fuel reserves, lubricants and boiler water;
4) total displacement, equal to the standard plus full reserves of fuel, lubricants and boiler water, ensuring the specified cruising range at any speed;
5) largest displacement, equal to the standard plus additional supplies that the ship is able to accept until all storage facilities are completely filled: combat weapons (including mines on upper deck), fuel, lubricating oils and boiler water.
The volumetric displacement of a vessel is the main characteristic of a surface vessel and is determined by the volume of the underwater part of its hull. It is directly related to the weight displacement of the vessel, since according to Archimedes’ law, any floating body displaces a volume of water whose weight is equal to the weight of the body itself.
Volumetric displacement depends on the specific gravity of water (water density). IN fresh water, the specific gravity of which is equal to one, the weight displacement, expressed in metric tons, is numerically equal to the volumetric displacement in cubic meters.
Determination of volumetric displacement (volume of the immersed part of the hull) is carried out using one of the methods indicated below.
