Chapter 400: How can this be
The modern shipbuilding process has already entered the factory production. When the ship is on the design drawing, it is divided into sections, manufactured separately, and then hoisted and merged to form a new ship. If necessary, the segmented hull can also be outsourced to other shipyards, thereby reducing production pressure and costs.
In the early 90s, the advanced shipbuilding method was the segmented manufacturing method that An Shangyu said, in which a ship was divided into more than 100 sections and then re-spliced, 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 sectional shipbuilding method, which is only divided into 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, and if you listen to some of them, you will know that the shipbuilding method of the giant general section is more advanced. But he also has a lot of questions: "The weight of the total section has increased, and it will be more difficult to move." According to your plan, the shipyard may need a gantry crane of more than 800 tons, such a crane, the price is too expensive, why do you need 30 million US dollars, Dahua Industrial's shipyard investment is so large?"
"With a gantry crane, the price is really high. Su Cheng smiled preparedly, and said: "Dahua is ready to wait a few more years before purchasing such a large weight gantry crane, at this stage, in the case of not many orders, we are ready to separate the lifting and translation functions to deal with, such as the use of lifting towers to complete the lifting function, the use of hangers to complete the translation ......"
"In this way, the cost is only one-tenth of that of the gantry crane. Smart, too smart" An Shangyu couldn't help but exclaim, just such a sentence made his trust in Su Cheng greatly enhanced. People who haven't really thought about this process will not delve into the problem of process cost reduction, because in essence, cost reduction is a secondary content of process research, and you have to study the process that can be used first, and then consider the problem of cheapness.
That is, we must first solve the problem of whether there is a problem, and then solve the problem of whether it is good or not.
An Shangyu didn't know that the tradition of Chinese shipyards has always been to be cheap and easy to use. For example, things like large-tonnage gantry cranes, even if they enter, large shipyards do not dare to purchase more.
The method that Su Cheng said was the one that the shipyards used the most. Although the efficiency is lower, the cost is only one-tenth, and it is better to be cheap anyway.
Li Cangming knew that Dahua Industrial was not prepared for the shipbuilding method of the giant general section, but when he heard Su Cheng say this, he still felt excited. Because as early as during the discussion, he knew that Dahua Shipbuilding was developing in this direction, and the shipbuilding law mentioned by Su Cheng could really be implemented.
An Shangyu nodded frequently, and asked again after a while: "How do you solve the precision control? The splicing of two such large sections is much more difficult than the small segmented splicing." ”
"Laser 3D precision measurement and computer simulation calculation technology. Sioux replied without thinking about it. These are not new things, before the adoption of civilian shipbuilding, in the creation of space shuttles and aircraft carriers, such technologies were used. The key is that the ship's chief engineer should be able to use both 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 section shipbuilding method, although he cut the construction time of the ship by half, he did not actually invent any earth-shattering new technology, but only solved a series of small technologies.
Other designers may be able to solve some of these techniques, but when they see the difficulty of other technologies, they often choose to give up.
In addition, depending on the environment, whether or not to adopt the giant general section shipbuilding method will also change.
There's a reason why both the sectional shipbuilding method and the jumbo block shipbuilding method are gaining traction in the Asian region. Because of the rapid rise in the price of raw materials and equipment such as steel plates, and the reduction of world ship profits, Asian shipyards hold a large number of low-cost orders of a principal-even nature. In order to turn losses and increase profits, Asian shipyards can only greatly increase their shipbuilding capacity and try to insert new high-priced orders. Such a problem is not so serious in Europe and the United States, they are mostly century-old factories, and the cautious and complete contracts during the order period often allow them to avoid round after round of price increases. However, this has also made European and American shipyards increasingly fade into the shipbuilding industry.
The technology to dramatically increase the speed of shipbuilding can only be fully appreciated in Asian shipyards.
An Shangyu is no exception, scratching his ears and cheeks with joy and constantly asking questions.
Although Su Cheng is a half-tone, he doesn't show flaws when he says it air-to-air.
Liu Minghao was listening, and at first he had a smiling face watching a good show, and he was soon surprised.
He waited patiently for a while, grabbed Su Cheng and said, "Su Dong, let's rest for a while, you see that Mr. An Shangyu has only been here for a short time, and he is still tired." ”
"I'm not tired, I'm not tired. An Shangyu heard the translation, shook his head vigorously 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 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 section shipbuilding really possible?"
"Of course. ”
Liu Minghao looked like he was about to squirt blood: "This is a militaristic weapon, how can ......it be easily shown? You really picked up the sesame seeds and lost the watermelon. Do you know that the technology of an LNG ship can be compared to the technology of speeding up the construction of ships, and how many oil tankers and cargo ships our country needs every year? If we can save half the time, it will be ...... It's ......"
"Militaristic weapons?"
"Yes, militaristic weapons. After Liu Minghao finished speaking, he realized that he had already said this word, glared at Su Cheng and said, "Tell me, what's going on?"
Su Cheng Shi Shiran said: "Actually, it's 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 else? It's too difficult." Moreover, the core of the giant section shipbuilding method is off-site shipbuilding, that is, the giant section can be manufactured in different shipyards, and then assembled into ships in the core shipyard, which is the method of multinational companies. Our domestic shipyards do not have such ability for the time being, and it is estimated that they do not have such willingness. ”
"Are you still unhappy about the ship's business?" Liu Minghao couldn't help but say: "Let me say this, if there is this technology, I will explain it to you." ”
Su Cheng stretched out his hands helplessly and said, "I'm not for the ship's business, alas, I'm slandering him." ”
"What?"
Su Cheng sighed and said, "We haven't even mastered the sectional shipbuilding method, how can we engage in the giant general section shipbuilding method?" I was thinking that we should use a higher technology to bring over the technology that the Koreans have mastered now. Alas...... Now it is estimated that people have also come back to their senses. ”
He did it on purpose. Ahn Sang-woo will show great sincerity even if he is half-convinced, because this thing is originally half-true. The real part, he will believe the truth, and the false part, maybe he will think that Sioux City is suspicious.
Liu Minghao didn't care what Su Cheng said, and said directly: "Just say it, can the giant general section shipbuilding method be realized?"
"Yes, but you have to get the sectional shipbuilding method first, and then focus on some technologies. "Sioux City doesn't know much about this, but when he was studying, he did come into contact with it. His current level belongs to the level of seeing the relevant noun and knowing what it means.
Speaking of which, if you take a related exam, it is estimated that you will get 20 points. But in the world of heavy equipment, such a degree is actually enough. Because many technologies have been studied decades ago, but they are not used for various reasons, as long as Sioux City is willing to look through the literature, is willing to ask people, can organize professionals to conduct paper research, and make a research outline for the giant general section shipbuilding method, and research it, it can be done.
For ordinary people and companies, the key issue is the outlook for profitability. The investment in heavy equipment technology is often tens of billions, but the technology produced every year is innumerable.
Until there is no future, alternating current can lose to direct current, and what strange thing cannot happen. It's not uncommon for investors to hesitate a little 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, then I'll help you get this sectional shipbuilding method, you can sort out the giant general section shipbuilding method, but you have to guarantee it." Transfer of technology to domestic shipyards. ”
"Part of the technology can be transferred, to which shipyards to transfer, and when, I have the final say. Su Cheng held the initiative in his hands, and at the same time said: "Even if you don't help, I can get the technology of the sectional shipbuilding method and find Koreans, that is, to save money." ”
Liu Minghao hesitated for a moment, stretched out his hand, and said, "A word is a certainty." ”
"It's a deal. Sioux high-fived him.
"Cooperate with me. Liu Minghao said, opened the door, and shouted in a thick voice: "No, the technology is yours That's right, the transfer must go through the country, the militaristic weapon, not what you want to exchange." ”
With exaggerated movements and tones, in the eyes of others, Liu Minghao and Su Cheng obviously had a big quarrel.
An Shangyu, who was reluctant to rest, hurriedly ran up and asked Su Cheng: "Su Dong, what's wrong?"
Su Cheng's head turned quickly, and he sighed: "That...... Giant general section 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 this be. ”
"yes, how can this be" Sioux City pretended to be annoyed.
An Shangyu patted his chest and said, "Don't worry, I'll help you ask." ”
After saying that, he went to the South Korean delegation to mutter. (To be continued)
