Modern shipbuilding technology has already entered factory production.When the ship is on the design drawing, it is divided into sections, manufactured separately, and then hoisted and combined to form a new ship.If necessary, the segmented hull can also be outsourced to other shipyards, thereby reducing production pressure and costs.

The advanced shipbuilding method in the early 90s is the segmented manufacturing method mentioned by An Shangyu. A ship is divided into more than 100 segments and then reassembled. The efficiency is several times higher than the traditional shipbuilding method.

The giant general section shipbuilding method can be regarded as an enlarged version of the subsection 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 several years, and he just listened to it, and he knew that the method of building large-scale ships is more advanced.But he also has many doubts: "The weight of the general section has increased, and the movement will become more troublesome. According to your plan, the shipyard may need a gantry crane weighing more than 800 tons. Such a crane is too expensive. For 3000 million U.S. dollars, Dahua Industrial’s shipyard has invested so much?”

"If you use a gantry crane, the price is really high." Su Cheng smiled preparedly, and said: "Dahua plans to wait a few more years before purchasing such a heavy gantry crane. At this stage, there are not many orders Next, we plan to separate the two functions of lifting and translation, 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 the gantry crane. Smart, so smart." An Shangyu couldn't help but marvel. Just this sentence greatly enhanced his trust in Su Cheng.People who have not really thought about this process will not study the issue of process cost reduction in depth, because in essence, cost reduction is a secondary content of process research. You have to research a usable process first, and then Then consider the issue of cheapness.

That is to say, we must first solve the problem of whether it is available, and then solve the problem of whether it is easy to use.

An Shangyu didn't know that the tradition of Chinese shipyards has always been to be cheap and easy to use.For things like large-tonnage gantry cranes, even if they entered, large shipyards would not dare to purchase more.

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

Li Cangming knew that Dahua Industry was not ready for the giant general shipbuilding method, but he still felt excited when he heard what Su Cheng said.Because as early as during the discussion, he knew that Dahua Shipbuilding was developing in this direction, and the shipbuilding method Su Cheng mentioned could really be implemented.

An Shangyu nodded frequently, and asked after a while: "How do you solve the precision control? The splicing of two such large total segments is much more difficult than the small segment splicing."

"Laser three-dimensional precision measurement and computer simulation calculation technology." Su Cheng replied without thinking.These are not new things. This technology was used in the manufacture of space shuttles and aircraft carriers before it was adopted in civil shipbuilding.The crux of the matter 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 lie in the level of IQ, but in the amount of knowledge and experience stored in the mind.

The first ship designer who adopted the giant general shipbuilding method shortened the construction time of the ship by half, but he did not actually invent any earth-shattering new technologies, 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.

Coupled with the different environments, whether to adopt the giant general shipbuilding method will also change.

There is a reason why both segmented shipbuilding and mega-segment shipbuilding have flourished in the Asian region.Because the prices of raw materials and equipment such as steel plates have risen, and the profit of ships in the world has decreased, Asian shipyards have held a large number of low-price orders with guaranteed capital.In order to turn around losses and increase profits, Asian shipyards can only greatly increase their shipbuilding capacity and try to insert new high-priced orders as much as possible.This kind of problem is not so serious in Europe and the United States. Most of them are century-old factories. The prudence and complete contracts in the order receiving period often allow them to avoid round after round of price increases.However, this also makes European and American shipyards gradually fade into the shipbuilding industry.

Only in Asian shipyards will the technology of greatly improving the speed of shipbuilding be given full attention.

An Shangyu was no exception, he scratched his head with joy and kept asking questions.

Although Su Cheng was half-toned, he spoke air-to-air without revealing any flaws.

Liu Minghao was listening, at first he still had a smile on his face, but soon he became surprised.

He patiently waited for an opening, then grabbed Su Cheng and said, "Su Dong, let's rest for a while, you see that Mr. An Shangyu has just arrived, and he is still tired."

"I'm not tired, I'm not tired." Hearing the translation, An Shangyu kept shaking his head and said, "When I'm working, 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 they arrived at the delegation's separate room, Liu Minghao said unhappily: "Su Dong, what you talked about with An Shangyu is true?"

"of course."

"Is this kind of giant general shipbuilding method really achievable?"

"of course."

Liu Minghao looked like he was about to squirt blood: "This is a military weapon, how can it be easily shown to others? You...you really picked up the sesame seeds and lost the watermelon. The technology of an lng ship can't compare with the technology of speeding up ship construction Do you know how many oil tankers and freighters our country needs every year? If we can save half the time, it would be..."

"Military weapon?"

"Yes, a military weapon." After Liu Minghao finished speaking, he realized that he had already said the word, and he glared at Su Cheng and said, "Tell me, what's going on?"

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

Liu Minghao was taken aback for a moment: "Why?"

Su Cheng looked like a fool, and said: "Why? It's too difficult. Moreover, the core of the giant general shipbuilding method is to build ships in different places, that is, to manufacture giant general sections in different shipyards, and then assemble them into ships at the core shipyard. It belongs to the method of multinational companies. Our domestic shipyards do not have such capabilities for the time being, and it is estimated that they do not have such willingness."

"Are you still unhappy about China Shipbuilding?" Liu Minghao couldn't help saying, "Let me put it this way, if there is such a technology, China Shipbuilding will explain it to you."

Su Cheng spread his hands helplessly, and said: "I'm not doing it for China Shipbuilding, alas, I'm blackmailing him."

"what?"

Su Cheng breathed a sigh of relief, and said, "We don't even master the segmented shipbuilding method, how can we develop a giant general segmental shipbuilding method? I was thinking of using a higher technology to deceive the technology that the Koreans have now. Sigh ...Now I guess people have come to think of it."

He did it on purpose.Even if An Shangyu is dubious, he will show great sincerity, because this thing is half-truth and half-false.The real part, he would believe it to be true, and the fake part, he might think that Su Cheng was the reason for the suspicion.

Regardless of what Su Cheng said, Liu Minghao said directly: "Just tell me, can the giant general shipbuilding method be realized?"

"Yes, but you must first obtain the segmented shipbuilding method, and then focus on researching some technologies." Su Cheng didn't know much about this aspect, but he did come into contact with it when he was studying.His current level belongs to the level of seeing related nouns and knowing what they mean.

To put it bluntly, at the level of Sioux City, if you take a related exam, you probably won't get a good score.But in the world of heavy equipment, this level is actually enough.Because many technologies have been researched decades ago, but they have not been used for various reasons. As long as Sioux City is willing to read the literature and ask people to ask questions, it can organize professionals to conduct paper research, and give the giant shipbuilding method a list. It is possible to study the outline and research it out.

For ordinary people and companies, the crux of the matter is the prospect of profitability.The investment in heavy equipment technology is often in the tens of billions, but the technologies produced every year are innumerable.

Before seeing the prospect, alternating current can lose to direct current, and what strange things can't happen.It is not uncommon for investors to hesitate for a while and delay a technology for five years.

Liu Minghao stared at Su Cheng's eyes for a long time, and said in relief: "Since you said so, then I will help you get this segmented shipbuilding method, and you can complete the giant general shipbuilding method, but you have to guarantee it. Domestic shipyards transfer technology."

"Part of the technology can be transferred, which shipyards to transfer to, and when to transfer, I have the final say." Su Cheng held the initiative in his hands, and said at the same time: "Even if you don't help, I can still get the piecewise shipbuilding method." technology, looking for Koreans is 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 rough voice: "No, the technology is yours, that's right, the transfer must go through the country, the military weapon, not what you want to change."

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

An Shangyu, who was reluctant to rest, hurried up and asked Su Cheng: "Su Dong, what's the matter?"

Su Cheng turned his head quickly, and sighed: "That... the giant general shipbuilding method, we can't 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."

"Yeah, how could this be?" Su Cheng pretended to be annoyed.

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

After speaking, he went to the South Korean delegation to mutter. (to be continued)
