The shipyard has only one super-large dock, which is a super-large dock with a length of 1,000 meters and a width of 200 meters, which is fully capable of building all the large ships currently available in the world. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

Even building an aircraft carrier is trivial, because even the world's largest nuclear-powered aircraft carrier, the Nimitz-class, is only more than 300 meters long and has a displacement of only 100,000 tons.

And the aircraft carrier, although it is large, is not the largest ship in the world, it is just the largest military ship in the world.

The world's largest ships are those very large ocean-going tankers, such as the largest ocean-going tanker built by man, the Nock Nevis.

The ship was built in 1976 by Japan's Sumitomo Heavy Industries and launched in 1981, it is a supertanker with a length of 458 meters and a displacement of 800,000 tons.

However, the fate of the ship was bumpy, it was sunk by a missile in 1988, then salvaged and restored in 1990, and then dismantled in 2009, leaving only the anchor and placed in a museum in Hong Kong for preservation and exhibition.

And now Yang Yu is building a shipyard, but is building a 1,000-meter-long, 200-meter-wide super-large dock, after the completion of not only the world's largest dock, but also the largest indoor dock, because the entire shipyard is actually a huge dome factory.

With such a large dock, he could build a supership even bigger than the Nork Nevis megatanker, which was a thing of the past, if he needed to.

And because he now has this super-extruded material that is as hard and strong as steel, he can build ships super fast.

It can be said that as soon as he officially announced the adoption of this new material for the construction of ships, it will definitely cause an uproar again.

In fact, when Yang Yu began to use super extruded materials to build in industrial parks, skyscrapers, and shipyards, it has attracted wide attention from the world media.

It's just that at the moment they only know that this super material is a super material that can be quickly used to build houses, and they don't know about its other properties.

Because of these places, people from the outside world can't get close to them at all, and you can't see anything by looking at them from a distance.

Even if it is a shipyard, because of Yang Yu's shipbuilding in the magic capital, the entire shipyard was built into a fully enclosed structure at the beginning.

At the same time, the giant dock he is building in an enclosed manner is not the kind of dry dock that is below sea level and fills in by isolating seawater, nor is it the kind of floating dock that can be built outside the shipyard that can be raised and lowered in the water.

Because he does not build ships entirely of traditional steel, but uses a large number of super-extruded materials with light weight and huge buoyancy.

Therefore, this kind of dock is a kind of skid rail hoisting dock designed completely specifically for his shipyard, through the slide rail and the giant lifting equipment inside the shipyard, the hydraulic lifting system, and the way of lifting and hoisting.

Now the entire dockyard is in an enclosed space, and as long as his ship is not officially launched, and the gate of the shipyard is not opened, no one else can see anything from the outside, only that it is a huge factory built on the shallows of a lonely island.

In addition, Yang Yu's construction sites are now patrolled by personnel sent by the military as security guards, and there are exclusive guards of the factory arranged by Yang Yu himself, as long as Yang Yu himself wants to announce it, it is impossible for the outside world to get any accurate information.

Because as long as a suspicious person appears, they have already been discovered and expelled before they can get close.

Yang Yu's shipyard is currently building a giant slide rail and a giant gantry crane with adjustable size inside this dock.

This adjustable size of the slide rail, in fact, can be used to fix different sizes of ships of different sizes of the adjustment device, the whole giant slide rail in the sea sliding to a certain length, will be lowered like a lever, and then through the gantry crane and the hinge on the other side of the ship to let the ship slowly slide into the water, and then by hoisting the ship in the water.

This way of entering the water is not too much of a problem for small ships, no matter what materials are built for ships, but if it is a very large ship, such as an oil tanker with more than 100,000 tons in the air, it is difficult to enter the water in this way.

For example, Yang Yu wants to build an ocean-going freighter with a length of 400 meters and a width of 100 meters, and only the keel frame of the entire hull will be built with special steel, just like a reinforced concrete structure, the frame is made of steel first, and then the hull and internal structure of the ship are built with this super expanded material.

90% of the materials used in the construction of ships are made of this super puffed material, so the construction of a 400-meter-long, 100-meter-wide and 40-meter-high ocean-going freighter will weigh up to 5,000 tons after it is fully completed.

But if it is built with steel, then it must be at least 100,000 tons or more in the air, and it is precisely because the weight of the whole ship is only a few thousand tons or 10,000 tons that Yang Yu will use this simple dock.

Because if it is to build such a huge displacement dry dock, it will take a long time to build all kinds of infrastructure, so in order to save time, Yang Yu also uses this simple method.

And if he uses this material to build a ship, it is completely different from other ships in terms of design, because the ship built with this material has to be redesigned because of the light weight of the hull itself, and the width, length, and height ratio of the hull must be redesigned.

Because the hull is lightweight, the width is narrow, and if the height is too high, it is easy to cause the hull to roll over due to the light weight of the hull.

Therefore, if the hull built from this material is at the same height and length, then the width ratio is much wider than that of other hulls.

Also because of the light weight and buoyancy of the hull, the waterline of the hull is relatively much shallower, such as a 400-meter-long, 100-meter-wide giant ship, when it is empty, the draft is less than 1 meter.

Therefore, the height of the hull must not be too high, otherwise it will be easy to capsize as soon as the wind and waves come.

And because of this special design, ships built with this material will not use traditional propeller drive like other ships, but will use a shaftless pump propulsion system that can turn and lift 360 degrees.

That is, similar to the in-wheel motor of electric vehicles, the entire propeller does not have a central shaft, and this technology has long been available, but it is not mature and cannot be put into use.
