Chapter 405 Window Paper

Li Cang smiled dumbly and said: "The technology of building ships directly on the site without a dock, our country has studied my impression, and the exploration of the No. 3 offshore drilling platform is the flat ground shipbuilding technology used. However, 10 years have passed, and more and more docks have been built in our country, and flat land shipbuilding seems to be a little unable to keep up. And, what does that do for speed?"

"Exploration 3 is not using real flat-ground shipbuilding technology. When Su Cheng was studying oil storage and transportation, he came into contact with the construction technology of some LNG ships and oil tankers, and talked generally: "The flat shipbuilding technology I am talking about should be combined with the sectional shipbuilding method, preferably the giant general section shipbuilding method, and adopt the large-scale modular way of hull parts to complete the shipbuilding work on flat ground, and the ship will not be launched at all before the construction is completed, so that it can not be affected by the dock and slipway, and more manpower and material resources can be invested." ”

What he said was not very clear, but Li Cang understood. Due to the limitations of cranes and other equipment, Exploration No. 3 was actually installed on the water surface back then. It is not so much a flat shipbuilding as a surface shipbuilding.

He is a ship expert who can be an academician in the future, and for this upcoming new technology, he first expected it emotionally, and asked: "If there is no dock, large-scale construction is indeed advantageous, but this method you said, first of all, how to solve the problem of ship launching?"

"Lay rails on the flat ground, let the built boat lean against the unpowered tug on the shore, and then tow the tug to the shore. After sinking the tugboat into the water, the hull surfaced. What Su Cheng said was almost all the information he remembered.

Li Cang fell into deep thought.

Just when Su Cheng thought that there was a problem with the phone, Li Cangcai suddenly woke up and asked, "Su Dong, are you in this city?" ”

"I'll have someone buy your plane ticket for you. "Sioux City needs a ship specialist, a real specialist, more than ever.

There are actually two types of experts in the world, one is the rigorous scientific expert, who essentially solves problems through mathematics. One is the brick family that eats and waits for death, essentially solving problems through imagination. The latter is like a rat, not only spoiling pot after pot of soup, but also surprisingly fecund.

The reason why China in the 90s had a diploma fever was precisely because of the lack of real specialists. The most young and energetic people, but because of the experience of the 70s, they have not learned anything at all, and occasionally there are two guys who have passed the test in the dark, so they can only dominate in the country, and they are not enough to see in the industry that requires global competitiveness, such as ships or oil.

Therefore, although Dahua Industry has been high-end to the point where it can directly find academicians, Sucheng still chose a scarce variety like Li Cang to cooperate.

At 10 o'clock in the evening, Li Cang and his two assistants arrived in the port smoothly.

Sioux City greeted him personally.

Sitting in the car, Li Cang couldn't wait to ask: "Does Su Dong have all the designs for flat land shipbuilding?"

"Where do I have it. However, this technology should not be difficult. Su Cheng said this because when he was in college, his teacher said so.

At that time, the associate professor who taught oil storage and transportation was full of regret and said that flat ground shipbuilding is essentially an exquisite design, and by piercing a layer of window paper, you can achieve huge benefits. As a result, the patent was registered by a foreigner, and even if we saw the situation outside the window, we could not use it.

College boys are either rich and handsome or angry. Sioux City listened very carefully at the time, and until now, he remembers that the layer of window paper was the problem with the launch of the ship.

When the boat is in the dock, it is convenient to launch the water, but it is not so easy to launch on a flat field.

The domestic exploration No. 3 is the final hoisting completed by water operations, which is very difficult, the fault tolerance rate is very low, and it cannot be used to produce larger ships.

The use of unpowered tugboats and sleeper rails can solve the problem of launching water relatively easily.

Li Cang was full of interest in this plan, so he hurried to come. Seeing that Su Cheng could not provide more information, he said with regret: "The weight and volume of the hull, as well as the gravity and buoyancy of the water, will affect the safety of the ship launching. ”

"How about using the 202 ship for experiments?" Su Cheng said, introducing.

Li Cang shook his head when he heard this, and said, "For the same ship, there is probably no difference in speed between flat ground shipbuilding and dock manufacturing. The advantage of using flat land shipbuilding is that it can save the time of the ship in the dock, and there is no need to build sections and wait for the dock, so the flat land shipbuilding method can be used when multiple ships are built at the same time. ”

"Then use the 201 ship for experiments. "Sioux City is talking about the ships ordered by Dahua Transportation. Both ships are of the same type, and in order to speed up ship 202, the construction of 201 has been slowed down.

Li Cang naturally would not refuse, there was a 10,000-ton giant ship to do experiments, this kind of thing is the dream of every ship expert. Even if he focuses on basic research, he will not give up this opportunity.

However, looking at Su Cheng's "melancholy" smile, Li Cang was a little embarrassed and asked: "You said that the estimated delivery time of ship 202 has been delayed, and it will not delay you too much if you use ship 201 for experiments." ”

"The total number of our workers is sufficient, but the number of core workers is relatively small. Ship 201 can do as fast as it can. Although the 202 ship will not be delivered on time, we must not stop at this time. The flat-ground shipbuilding method is regarded as a technical reserve, and it will be able to play a role next time. ”

Hearing Su Cheng say this, Li Cang couldn't sit still, pondered for a long time, and said: "Actually, the No. 202 ship is not completely out of chance, there are still 2 months to go." ”

"68 days. ”

"I can help you find some advanced mechanics. ”

"The current situation...... If we poach people from shipyards such as CSSC, I am worried about the morale of Dahua Shipbuilding's own employees. ”

Li Cang knew about the trap of the ship, and hurriedly said: "I have nothing to do with the shipbuilding, in fact, there are some senior ship workers who do not belong to the shipbuilding. ”

"Not in the ocean. ”

"It doesn't belong to the ocean. ”

"Oh, where are the senior shipwrights?" Sioux City was interested. What they are lacking now is high-level mechanics, especially professional ship workers. In some places, it could have been done quickly, but in order to wait for a small number of senior technicians, the overall speed was delayed. According to the eight-level labor system inherited from Dahua, 7 and 8 ship welders are the most lacking, and with the end of sectional manufacturing, the overall ship manufacturing will need more vacancies.

Li Cang pointed at himself with a smile and said, "In school." Our school has a small shipyard for students to practice and practice, although they are all small boats, but the level of workers is quite high, especially those senior workers, it is definitely no problem to do 10,000-ton freighters. ”

Su Cheng only had to listen to the first sentence he said, nodded again and again, knocked his head and said, "Why didn't I think of it." HR idiots!"

The school is a public institution, and in the Chinese system, the status is significantly higher than that of the factory, and it is a good-sounding and comfortable position. The title of senior engineer in the school is equivalent to that of professor or associate professor, and the career growth is also quite good.

It's not so easy for Dahua to poach them, but it's easy to borrow them.

Because the school's experimental shipyard is actually not necessarily working. It belongs to the small and all-era product, and the internship of students can be put into Dahua Shipbuilding, although those free labor is very annoying, but the college students of 92 are more or less obedient to the command...... On the other hand, the school in 92 has just begun to bear the baptism of the market economy, and Dahua Industrial has to borrow people out without paying too much price.

As long as it takes a short period of time, Dahua's own workers will grow.

Senior mechanics have grown up on the job. As long as a welder is not stupid, welding a few kilometers and dozens of kilometers, he can always weld a level of six or seven levels. It is impossible for any school to provide so many materials for them to practice, but the factories that keep receiving orders have job opportunities.

Su Cheng sincerely thanked Li Cang and immediately began to move.

With Dahua's current resources, he can contact those schools normally, and he doesn't even need Sioux City to come forward.

Three days later, the first batch of senior mechanics from the school appeared at the Dahua shipyard. The speed of the No. 202 ship also quietly accelerated.

After settling Li Cang, allowing him to have sufficient power and resources, and using the No. 201 ship as an experimental ship to study the flat ground shipbuilding method, Su Cheng finally freed his hands to review the China Shipbuilding poaching incident.

At the monthly board meeting in mid-November, Su Cheng said unequivocally: "When Dahua Shipbuilding enters the LNG ship, it will inevitably encroach on the traditional field of China Shipbuilding. The trap set by the Chinese Shipbuilding to poach us is not so much their counterattack against us as it is an inevitable occurrence. Although it happened suddenly and caused us some trouble, it is also beneficial to sober up earlier. Now, the Strategy Department must come up with a plan in the near future to deal with the challenges that CSSC may initiate. ”

Huo Chang also said: "No matter when we master the technology of LNG ships, before and after that, we have to do a lot of ordinary ship training, while balancing the cost. The current profits of CSSC are mainly concentrated in 20,000 to 150,000 tons of freighters. ”

Su Cheng nodded and said, "We must give a resolute response, if they think we are easy to bully and pounce on them, it will be troublesome." ”

"Hit back on the ship?"

"Fight back Zhan Zhifang!" Su Cheng waved his arm and said, "Whoever comes out will hit whomever he wants." ”

"Okay!" Dahua's board of directors is still mostly young, and when it comes to fighting, they are all excited.

Only Zhong Zhigen asked: "How to fight back?"

Zhan Zhifang's work includes winning orders in China. We grabbed his order. ”

Zhang Chao asked in surprise: "We can't do it even if we grab the order." ”

"It didn't work before, but Professor Li Cang's research has made progress, and judging from the situation of the 201 ship, it is true. However, our first target is to focus on small and medium-sized vessels, mainly to accumulate experience. "Sioux City is still a decision made based on commercial considerations, and the impact of small and medium-sized ships on CSSC is not large, but it has a good role in promoting Dahua Industry, and it will also make Zhan Zhifang very uncomfortable.
