Super Weapon Swap System

For a ship transporting liquefied natural gas, the challenge is the same. Liquefied natural gas needs to be kept at minus 162 degrees.

Such a low temperature can not be realized by a refrigerator like a refrigerator truck. We must rely on our own excellent welding technology to weld special materials into huge storage containers. This welding is the most difficult of all technologies.

"In the 1950s, the West conquered the manufacturing technology of liquefied gas ships, but so far, there are no more than ten such ships in the world, and we should also be among the world-class ship manufacturing fields." Lao Zhang said with a proud smile on his face.

He has been in the shipyard all his life, which is almost the same as Makarov's experience. He started as an ordinary welder and has risen a little bit to the present. At the same time, he has also witnessed the strong development of the domestic shipbuilding field.

In the field of military ships, we have been able to build aircraft carriers, and in the field of civil shipbuilding, we also want to build our own LNG cargo ships!

If we do not build such ships, the shipbuilding industry of Han country can never be considered as the most powerful and can not shine on the world shipbuilding stage. This is also part of realizing the national strategic goal and showing our great power spirit.

As an industrial power, we must be able to build such cargo ships. Moreover, this is also related to the national energy strategy. China is rapidly becoming an energy importing country. China needs to import a large amount of oil and a sufficient amount of natural gas. With the gradual importance of environmental protection, there will be more demand for natural gas, which requires a large number of natural gas cargo ships to transport. If it can't make it by itself, Then you can only buy it from abroad at a high price.

Facing this challenge, they made great efforts.

"There are mainly two types of liquefied gas storage, independent storage tank type and membrane type. The former is to place cylindrical, tank, spherical and other tanks in the ship. In appearance, you can see the tanks protruding from the hull, while the latter adopts double shell structure. The inner shell is the bearing shell of the cargo tank, which is similar to that of the oil tanker. The latter has high volume utilization rate and light structural weight, but At the same time, it is more difficult, so we decided to start with the former, build several ships and master the technology before building the latter. "

Lao Zhang introduced and brought the people to the construction site.

At this time, pieces of shiny special plates have appeared in the view of everyone. At the same time, soothing music is still playing on the construction site.

"While building the hull, we also began to weld these most important gas storage tanks. They are spherical. Now, the spherical tanks containing liquefied natural gas are welded here."

Then Lao Zhang smiled: "we all call this work embroidery on steel plates."

Qin Guan nodded and said, "let's just look around. Don't go up and affect the workers' work."

Qin Guan knew the difficulty of this kind of welding.

Yinwa steel is a special steel suitable for this ultra-low temperature. This steel is relatively thin, and the requirements for welding are very strict. To what extent? No sweat drops on it, no fingerprints, no extra pressure on it, not even a pen.

What if this happens?

It will be scrapped. The steel plate being welded should be replaced, and the surrounding steel plates connected with it should be replaced.

At this time, the workers were working under such requirements. The shiny yinwa steel looked like a mirror and showed everyone clearly. The welders were calmly listening to music and welding steadily, just like fishing for copper money in a boiling oil pot and chopping meat on the back of zhenguanxi. Their work was of great importance.

Not only sweat drops can't fall down, even a little false welding will bring terrible consequences. This is a natural gas cargo ship. Once a solder joint leaks during navigation, the consequences will be disastrous and the whole ship will be destroyed.

The spheres storing natural gas are powerful bombs. Moreover, this is not the most serious. If there is a leak during unloading at the port and ignites the natural gas ship, the whole port will be blown up.

Therefore, it is quite a test for workers, not only superb technology, but also a stable state of mind.

"We have to check the workers' bodies every day. If the heartbeat is not in line, we can't go up. If the blood pressure is high, we can't go up. If we are in a bad mood, we can't go up." Lao Zhang said next to him, "in the past, we used to pay attention to minor injuries. Now, in this kind of welding, needless to say minor injuries, even minor rhinitis won't go up."

Qin Guan nodded: "yes, these craftsmen are the most precious wealth. We will soon have a special program for craftsmen from large countries, and there will be reporters to interview. You should also be prepared to select several excellent craftsmen for interview. This is a way to show our national strength, but you can't fall off the chain."

When Qin Guan said this, old Zhang Dun understood: "don't worry, we are made in the Han country. It's world-class and different from the island country."

When Lao Zhang said this, he specially patted himself on the chest: "when we launched the LNG cargo ship, there were leaders who had questions. At that time, I said that if something went wrong, I would be held accountable. We have built a ship all our life. There is no aircraft carrier on the ship. It must be a bit challenging on the ship."

This kind of super cold storage on the sea is the most challenging cargo ship in the world. Of course, they have to take this task and show their own style to their superiors. It is absolutely no worse than the shipyards in the north.

Hearing this expression of determination, Qin Guan smiled and nodded: "don't worry, although the aircraft carrier ship can't reach you, you still have a chance for the amphibious attack ship used by the Navy. The shipyard in the North has a lot of tasks and is busy. There will certainly be orders for you. You can't fall off the chain at that time."

When Qin Guan said this, he was already very serious.

The Navy will soon have a formation of three aircraft carriers, the Chinese navy will become the second largest naval force in the world, and the construction of amphibious attack ships will soon begin.

According to the plan, this kind of attack ship should be launched for service as soon as possible. Therefore, there is also a chance to build it here.

Lao Zhang had just made it clear that he was asking for war. He also resented the task of not building an aircraft carrier. Now, only 10000 ton destroyers are not fun at all.

Qin Guan has promised him the task of building amphibious attack ships, which are 40000 tons. In many countries, they can play the role of aircraft carriers.
