Technological Hegemony

"Has the design of the engineering ship been completed?" Luo Jia was slightly taken aback.

"Well, all the designs have been completed." An Ran said.

"Did the computer simulation test pass?"

An Ran frowned, "Look at what you said, if I didn't pass the simulation test, I wouldn't tell you. As we expected, all the performances have met expectations."

Luo Jia breathed a sigh of relief, "Although the engineering ship is a small project of ours, it is still very happy to be able to complete it smoothly."

"Professor Ouyang will come over the day after tomorrow, and then show him our design."

An Ran nodded.

It may be that Xingchen Technology has too many big projects. An engineering ship for installing offshore wind turbines did not make the two of them too excited.

The two discussed some other matters, and then they split up and went to work on their own.

In the blink of an eye, the day after tomorrow, Professor Ouyang arrived at Xingchen Technology. He did not come alone, he also brought his student Sun Jingtao, and Ning Zeping, the chief engineer of Huaxia Power Grid.

Professor Ouyang is not only outstanding in knowledge, but also one of the few bigwigs in the academic world who are qualified to walk around the study room.

For such a great man with a detached status, Luo Jia must of course welcome him personally.

Fortunately, Professor Ouyang and Chief Engineer Ning are both academics, they have no airs and are easy to get along with.

Luo Jia invited them to his office, and asked the administrative department to serve tea and water, so as to serve the two big cows.

"Do you know why we came here?" Professor Ouyang took a sip of tea and asked Luo Jia with a smile.

"It has been almost a month since the supercapacitors were sent to the grid for testing. It should be that the grid has some opinions on our capacitors." Luo Jia said.

Chief Engineer Ning waved his hands again and again, "Don't say that, we don't dare to comment."

"To be honest, after the supercapacitor was built as an energy storage center, we were all surprised by its good performance. There was no excessive self-discharge problem at all, and the average loss rate per 24 hours did not exceed 6%! "

"At first we felt that

If the self-discharge loss rate can be 20%, it is acceptable, and the result is only 6%! Beyond imagination, completely beyond imagination! "

Capacitors are inherently self-discharging.

After all, everything has pros and cons. Capacitors can be repeatedly charged and discharged hundreds of thousands, or even millions of times, which is suitable for long-term large-scale use, which is far beyond comparison with lithium batteries.

Correspondingly, parameters such as energy density and self-discharge are much weaker than lithium batteries.

Six percent loss in 24 hours is already the maximum capability of Star Technology. If you want to improve it, unless the legendary graphene can be put into use in large quantities.

From the current technology point of view, graphene is good, but the price is comparable to gold, and the price/performance ratio is terrible.

Therefore, scientific research is difficult, and what is more difficult than scientific research is technology application. There are many advanced technologies in the laboratory, but not all technologies can be put into large-scale use and create social value.

Luo Jia said with a smile, "From this point of view, we are on the right path by taking the path of high-density carbon materials. The price is not high, and the grid can still be satisfied."

"I don't know, how about the cost of energy storage after grid accounting? Is there any value for large-scale use of supercapacitors?"

Ning Zeping said happily, "Cost is a thing that is used in different scenarios, and the final results obtained are also different."

"But according to our estimates, it should be around three cents per kWh on average."

Luo Jia nodded. The cost of storing a kilowatt-hour of electricity is about three cents. Although it is not low, it is at least much better than discarding the excess electricity directly.

Professor Ouyang sighed and said with emotion: "I am 70 years old this year. People who have stepped into the coffin with two legs did not expect to have the opportunity to see the day when electrification is popularized on a large scale. Thanks to you all. The hard work of Star Technology."

Luo Jia hurriedly said modestly, "Don't say that, a good person like you will surely live a long life."

"Since you two are here today, I have something else here that I want to show you."

After speaking, Luo Jia asked the administrative department to bring in the model of the engineering ship, and made it overnight with a 3D printer, so that it would be more intuitive when showing it to Professor Ouyang.

After seeing this huge model with a length of more than three meters, the two old people all stood up, studied around the model for a long time, and then said in unison in surprise: "Jack-up platform ship?"

Luo Jia hummed, "Yes, this is a self-elevating platform installation vessel designed by us, which is specially used to install offshore wind turbines."

"Look, you two, this is a piling machine, and this is a self-elevating installation machine. They are in a synergistic relationship. While driving piles on the seabed, they are combining the subsea platform."

"The one at the stern is a large mechanical arm, used to fix the fan..."

Luo Jia explained to the two experts that he felt that the efficiency of the jack-up platform ships currently used to install offshore wind turbines was too low, so he concentrated the strength of the hardware department and redesigned this integrated installation ship. few.

The two elders showed unbelievable expressions. After a long silence, they sat down again. Ning Zepinghu asked: "How do you know that we lack this thing?"

Luo Jia smiled and said, "This shouldn't be a secret, right?"

"At present, only Huadian has an installation vessel in China, and the two of Longyuan and Zhenhua Heavy Industry have not launched yet."

"Furthermore, Huadian's ship was on a mission for the first time. When it was doing maintenance on the Donghai Bridge, something went wrong. It shows that our installation ship may have a lot of trouble in terms of design rationality."

"Of course, this is all my speculation. After all, I have never been on the Huadian ship to see it, but my speculation is based on a reasonable premise."

"It is also a platform lifting installation ship, designed by Germany's Rheinland Group, and produced by South Korea's Daewoo. The SEA BLEEZE installation ship has zero failures in 3 years, and we have been lying on the ground for the first time. I am afraid that there is no way to explain it just because of bad luck. of."

Both Luo Jia and An Ran have the same problem. When it comes to professional issues, they will enter a state of selflessness, speak quickly, and don't consider other people's feelings.

Gradually, the faces of Professor Ouyang and Chief Engineer Ning Zeping turned green.

"I heard that after the Donghai Bridge incident, OLC, a subsidiary of the German Rheinland Group, was first invited. As the second largest offshore wind power construction company in the world, OLC took 3 weeks without even making a geological analysis. Later You had no choice but to invite Denmark’s A2Sea, and A2Sea only took 4 days to complete not only the geological analysis but also the construction plan.”

"It is not difficult to see from this that the technology of the Germans is really inferior to that of Denmark. Vitas is the manufacturer of wind turbines, A2Sea is the construction company, and Ramboll is the design company. The three masters are all above the Germans."

"We used to think of Siemens as our main competitor. It was too simplistic. It is actually the Danes who are leading the world in this field."

Luo Jia seemed to be talking to himself. At this moment, he finally raised his head, but he didn't stop talking.

"According to the 12th Five-Year Plan, 30,000M of offshore wind power should be built within five years, and Huadian's ship can also undertake 200M of installation tasks every year, which is too far behind."

"We thought there was an opportunity here, so we launched this integrated installation ship project. According to our calculations, it should be no problem for a single ship to receive 1,000M installation tasks per year."

"At present, our country seems to have the idea of ​​renting and installing ships from Europe. I checked the international quotations, and it seems to be 150,000 US dollars per day. Although our ships are more reasonable and efficient than the Rheinland Group, the rent only needs to be as high as They are the same, just give $150,000."

"Both of you are experts in the electrical field, do you think my idea will work?"

Luo Jia finally finished talking about his idea, but no matter how he saw the expressions of the two old people were not right, he was very suspicious, thinking that he had said something wrong.

After a moment of silence, Chief Engineer Ning finally said, "Okay, as expected of the Iron and Steel Boys, they are so upright, so ruthless, they ripped our pants off."

Leaning back, Chief Engineer Ning said bitterly, "It's just like what you said. At present, we only have the Huadian installation ship, and the design is not reasonable."

"Now that this is all said and done, let me tell you one more thing."

"Siemens wants to get involved in the installation business in Asia. The reason is very funny, because they are wind turbine manufacturers, and they have to undertake after-sales operation and maintenance services, and the failure rate in Asia is far higher than that in Europe. At first, they thought it was caused by the weather on the west coast of the Pacific Ocean. But it was discovered that it was because of a problem with the technology of our installation company.”

"So Siemens is negotiating with us now, selling us their installation technology and installation boats. I won't say the price, anyway, it's much more than 150,000 US dollars a day."

Slowly raising his head, Chief Engineer Ning stared at Luo Jia deeply, "Do you understand, this kind of installation ship is exactly what we need most at present!"

"Since supercapacitors are easy to use, of course we will launch green energy smoothly. Before we came here, we couldn't sleep worrying about engineering ships."

"After all, no matter how grand the idea is, it still needs construction equipment."

"Now that you've come up with a design, let the Germans go to hell!"

"You guys wait a moment, I'm going to call back and ask them not to sign the contract first."

After all, Chief Engineer Ning took out his mobile phone, walked out of Luo Jia's office, and went to find a secluded place to make a call.

"To be honest, how long have you been planning this?" Professor Ouyang asked Luo Jia curiously.

Luo Jia frowned, "It can't be considered premeditated, the engineering ship is a small project of ours. An Ran told me two days ago that when the design of the engineering ship was completed, I didn't pay much attention. After all, both Zhenhua and Longyuan Create, we are not the first."

small case?

Professor Ouyang suddenly felt a little tight in his chest. What Luo Jia said was urgently needed in the power industry turned out to be an insignificant small item.

But think about it, Star Technology has done too many shocking projects, and designing a kind of installation ship is really nothing to them.

People are more popular than people, Professor Ouyang shook his head helplessly, "To tell you the truth, Longyuan and Zhenhua's ships have stopped working because the design is not reasonable enough. If your ships can pass Lao Ning's simulation experiments, It is equivalent to saving their lives, otherwise, they can only wait to be slaughtered by Siemens."

Luo Jia's eyes lit up, he didn't know that the power department wanted to buy ships from Germany.

No wonder Mr. Ning was so excited, and after a long time, he made a mistake and cut off the German.
