Chapter 400 How can this be

The modern ship manufacturing process has already entered factory production. When the ship is on the design drawing, it is divided into sections, manufactured separately, and then uniformly hoisted and merged to form a new ship. If necessary, the segmented hull can also be outsourced to other shipyards, thus reducing production pressure and cost.

The advanced shipbuilding method in the early 1990s was the segmented manufacturing method mentioned by An Shangyu. A ship was divided into more than 100 sections and then reassembled, which was several times more efficient than the traditional shipbuilding method.

The giant general section shipbuilding method can be regarded as an enlarged version of the segmented shipbuilding method. It only divides more than 10 general sections, which can be completed by different shipyards, which indirectly improves the operation efficiency of large shipyards.

An Shangyu has been a ship engineer for 20 years. If you listen to it casually, you will know that the giant general section shipbuilding method is more advanced. But he also has a lot of questions: "The weight of the total segment has increased, and the movement will become more troublesome. According to your plan, the shipyard may need more than 800 tons of gantry cranes. Such a crane is too expensive. Why does it cost 30 million US dollars? Dahua Industrial's shipyard invests so much?

"If you use a gantry crane, the price is really high." Su Cheng had been prepared with a smile and said, "Dahua is ready to wait for a few more years before purchasing a gantry crane with such a large weight. At this stage, in the case of few orders, we are ready to separate the lifting and shifting functions, such as using the lifting tower to complete the lifting function, and using the hanger to complete the translation >

"In this way, the cost is only one-tenth of that of a gantry crane. Smart, so smart!" An Shangyu couldn't help marveling. Just such a sentence greatly enhanced his trust in Su Cheng. People who have not really thought about this process will not study the problem of process cost reduction in depth, because in essence, cost reduction is the secondary content of process research. You have to study the usable process first, and then consider the cheap problem.

That is to solve the problem first, and then solve the problem of whether it is good or not.

An Shangyu didn't know that the tradition of the national shipyard had always been cheap and easy to use. Things like large tonnage gantry cranes, even if they enter the new century, large shipyards dare not purchase more.

The method that Su Cheng said is the most used by shipyards. Although the efficiency is lower, the cost is only one-tenth. Anyway, it is cheap.

Li Cangming knew that Dahua Industry was not ready for the giant general section shipbuilding method, but when he heard Su Cheng's words, he still felt excited. Because as early as during the discussion, he knew that Dahua Shipping Industry was developing in this direction, and the shipbuilding law said by Sucheng could really be implemented.

An Shangyu nodded frequently, and then asked, "How do you solve the precision control? Two such large total segment stitching is much more difficult than small segment stitching.

"Laser three-dimensional precision measurement and computer simulation calculation technology." Su Cheng answered without thinking about it. These are not new things. Before the manufacture of civil ships, this technology was used in the manufacture of space shuttles and aircraft carriers. The crux of the problem is that the chief engineer of the ship should be able to use these two technologies and put them into practice.

Creative thinking often does not depend on the level of IQ, but on the amount of knowledge and experience stored in the mind.

The first ship designer to adopt the giant general section shipbuilding method. Although he shortened the construction time of the ship by half, he did not actually invent any earth-shaking new technology, but only solved a series of small technologies.

Other designers may be able to solve some of the technologies, but when they see the difficulty of other technologies, they often choose to give up.

In addition, if you are in a different environment, whether to adopt the giant general section shipbuilding method or not will also change.

There is a reason why both the segmented shipbuilding method and the giant general segmented shipbuilding method have been carried forward in the Asian region. Due to the rapid rise in the price of raw materials and equipment such as steel plates and the decline in the world's ship profits, Asian shipyards hold a large number of low-cost orders with capital preservation. In order to reverse losses and increase profits, Asian shipyards can only greatly improve their shipbuilding capacity and try to insert new high-priced orders. Such a problem is not so serious in Europe and the United States. Most of them are century-old factories. The cautious and complete contracts during the order period often make them avoid round after round of price increases. However, this has also made European and American shipyards increasingly fade into the shipbuilding industry.

The technology of greatly improving the speed of shipbuilding will only be paid full attention to by Asian shipyards.

An Shangyu was no exception. He scratched his ears and cheeks with joy and kept asking questions.

Although Su Cheng is half-toned, it is empty-to-empty and does not show any flaw.

Liu Minghao was listening. At first, he still had a smiling face to watch a good play, and soon he was also surprised.

He waited patiently for a moment, stopped Su Cheng and said, "Sudong, let's take a break first. Look, Mr. An Shangyu has just come here, and he is still tired."

"I'm not tired, I'm not tired." When An Shangyu heard the translation, he shook his head and said, "When I work, I often don't sleep for two or three days. This fatigue is nothing."

"It's better to take a break." Liu Minghao said, pulling Su Cheng's arm and leaving.

When he arrived at the separate room of the delegation, Liu Minghao said unhappily, "Su Dong, is it true that you talked to An Shangyu?"

"Of course."

"Can this giant general section shipbuilding method really be realized?"

"Of course."

Liu Minghao looked like he was going to spray blood: "This is a military weapon. How can it be easily shown to others? You... You really picked up sesame seeds and lost the watermelon. The technology of an LNG ship is not as good as the technology of speeding up the construction of ships! Do you know how many oil tankers and cargo ships our country needs every year? If you can save half of the time, it's simply...is..."

"Military weapon?"

"Yes, the military's weapon." After saying that, Liu Minghao realized that he had said this word. He stared at Su Cheng and said, "Tell me, what's going on?"

Su Cheng Shiran said, "In fact, it's also simple. We can't actually use the giant general section shipbuilding method."

Liu Minghao was stunned: "Why?"

Su Cheng looked like a fool and said, "Why? It's too difficult. Moreover, the core of the giant general section shipbuilding method is off-site shipbuilding, that is, the giant general section can be made in different shipyards, and then assembled into ships in the core shipyards, which belongs to the method of multinational companies. Our domestic shipyards do not have such a capacity for the time being, and it is estimated that they do not have such a will.

"Are you still unhappy about the ship?" Liu Minghao couldn't help saying, "Let me put it this way. If there is this technology, I'll explain it to you."

Su Cheng spread out his hand helplessly and said, "I'm not for the middle of the ship. Alas, I'm deselying him."

"What?"

Su Cheng took a breath and said, "We don't even master the segmented shipbuilding method. How can we do the giant total segment shipbuilding method? I'm thinking of using a higher technology to bring back the technology that Koreans have now. Alas... Now I guess they have also had an aftertaste.

He did it on purpose. Even if An Shangyu is skeptical, he will show great sincerity, because this thing is half true and half false. In the real part, he will believe that it is true, and in the false part, he may think that Su Cheng is suspicious.

No matter what Su Cheng said, Liu Minghao said directly, "Just say, can the giant general section shipbuilding method be realized?"

"I can, but I need to get the segmented shipbuilding method first, and then focus on some technologies." Su Cheng doesn't know much about this, but when he was studying, he did come into contact with it. His current level belongs to the extent that he sees the relevant nouns and knows what it means.

Speaking of which, Sucheng's level, if you take a relevant exam, it is estimated that you will get 20 points. But in the heavy equipment industry, this degree is actually enough. Because many technologies have been studied decades ago, but they are not used for various reasons. As long as Su Cheng is willing to turn over the literature and ask, he can organize professionals to conduct paper research, make a research outline for the giant general section shipbuilding method, and study it, and it can be done.

For ordinary people and companies, the key to the problem is the profit prospects. The investment in heavy equipment technology is often tens of billions, but countless technologies are generated every year.

Before the prospect is not seen, the alternating current can be defeated by the direct current, and there is nothing strange that can't happen. It is simply normal for investors to hesitate for a moment and delay a technology for five years.

Liu Minghao stared at Su Cheng's eyes for a long time and said with relief, "Since you said so, I'll help you with this segmented shipbuilding method. You can figure out the giant general stage shipbuilding method, but you have to guarantee it. Transfer technology to domestic shipyards.

"I have the final say on which shipyards can be transferred, which shipyards can be transferred, and when it will be transferred." Su Cheng took the initiative in his hand and said, "Even if you don't help me, I can get the technology of segmented shipbuilding and find Koreans to save money."

Liu Minghao hesitated for a moment, stretched out his hand and said, "It's a deal."

"It's a deal." Su Cheng gave him a high-five.

" cooperate with me." Liu Minghao said, opened the door and shouted in a loud voice, "No, the technology is yours. The transfer must go through the country and the military weapon. You can't change whatever you want."

With exaggerated movements and tone, in the eyes of others, Liu Minghao and Su Cheng obviously had a big quarrel.

An Shangyu, who was reluctant to rest, rushed up and asked Su Cheng, "Su Dong, what's wrong?"

Su Cheng's head turned quickly and sighed, "That... the giant general section shipbuilding method, let's not talk about it anymore. Let's talk about other things."

"Officially banned?"

"Yes."

"This... This is an academic exchange. How can it be like this?"

"Yes, how can it be like this!" Su Cheng pretended to be annoyed.

An Shangyu patted his chest and said, "Don't worry, I'll ask for you."

After saying that, he went to the Korean delegation to mutter.
