"The engineering ship has been designed?" Luo Jia was slightly stunned.

"Well, all the design has been completed," said An Ran.

"Have the computer simulation test passed?"

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

Luo Jia let out a sigh of relief, "Although the engineering ship is just a small project for us, it is quite happy that it can be completed smoothly."

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

Anran nodded.

Maybe Star Technology has too many big projects. A construction ship used to install offshore wind turbines did not make them too excited.

The two of them discussed some other things and went to work separately.

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

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

Of course, Luo Jia would like to welcome such a great man with a transcendent status.

Fortunately, Professor Ouyang and Chief Engineer Ning are both academic and have no airs and are easier to get along with.

Luo Jia invited them to his office and asked the administrative department to serve tea and water, so he was very happy to serve the two big bulls.

"Do you know why we come to your place?" Professor Ouyang took a sip of tea and asked Luo Jia with a smile.

"It has been almost a month since the supercapacitor was sent to the power grid for testing. It should be because the power grid has any opinions on our capacitors." Luo Jia said.

Chief Engineer Ning waved his hands repeatedly, "Don't say that, we dare not give any comments."

"To be honest, after the supercapacitor was established, we were shocked by the good performance after we formed the energy storage center. There was no excessive self-discharge problem at all. The average loss rate for every 24 hours is no more than 6%!"

"At the beginning, we thought that if the self-discharge loss rate could be 20%, it would be acceptable, and the result was only 6%! It was beyond imagination and completely beyond imagination!"

Capacitors naturally have the defect of self-discharge.

After all, everything has its pros and cons. Capacitors can be recharged and discharged hundreds of thousands or even millions of times repeatedly. They are suitable for long-term large-scale use and are far from comparable to lithium batteries.

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

The loss of 6% in 24 hours is already the greatest ability of Star Technology. If you want to improve it, unless the legendary graphene can be put into use in large quantities.

Judging from the current technology, graphene is good, but the price is comparable to gold, and the cost performance is very poor.

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

Luo Jia smiled and said, "It seems that we are taking the right path of high-density carbon materials. The price is not high and the power grid is still satisfactory."

"I don't know, what is the energy storage cost after grid accounting? Is supercapacitors worth a large-scale use?"

Ning Zeping said happily, "The final result of cost is different when used in different scenarios."

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

Luo Jia nodded. The cost of storing one-kWu is about three cents. Although it cannot be considered low, it is at least much better than directly discarding the excess electricity.

Professor Ouyang sighed and said with emotion: "I am seventy years old this year. Those who step into the coffin board with two legs didn't expect that there would be a chance to see a day when electrification is popularized on a large scale. Thank you for your hard work in Xingchen Technology."

Luo Jia hurriedly modestly, "Don't say that. A great person like you will definitely live a hundred years of life."

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

After saying that, Luo Jia asked the administrative department to carry the model of the engineering ship in and made it overnight with a 3D printer. This will make it more intuitive when it is displayed to Professor Ouyang.

After seeing this huge model that was more than three meters long, the two old men stood up and studied around the model for a long time. Then, in surprise, they said in unison: "Self-raising platform ship?"

Luo Jia said, "Yes, this is our self-lifting platform installation ship designed specifically for installing offshore wind motors."

"Look at it, this is a pile driving machine, this is a self-lifting installation machine, and they have a synergy relationship. While driving piles on the seabed, they combine the undersea platform."

"This stern is a large robotic arm, used to fix the fan..."

Luo Jia explained to the two experts that he felt that the efficiency of the self-lift platform ship used to install offshore wind motors is too low, so he concentrated the power of the hardware department and redesigned this integrated installation ship, which can improve the efficiency much more than in the past.

Both old men showed unbelievable expressions. After a long silence, they sat down again. Ning Zeping asked, "How do you know we are missing this thing?"

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

"There are only Huadian installation ships in China, and the two of Longyuan and Zhenhua Heavy Industry have not yet been launched."

"And the first time the Huadian ship was on a mission, there was a problem when it was repairing the Donghai Bridge, which shows that there might be a lot of trouble in terms of the rationality of the design of our installation ship."

"Of course, these are all my speculations. After all, I haven't seen it on the Huadian boat, but my speculations are all based on the premise of rationality."

"The same platform lifting and installation ship designed by Rhein Group in Germany and produced in Daewoo, South Korea, has 0 failures in 3 years. We were stuck in the first time we went on a mission. I'm afraid there is no explanation for the bad luck alone."

Luo Jia and An Ran are both the same problem. When they talk about professional issues, they will enter a state of selflessness, speak fast and do not consider other people's feelings.

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

"I heard that after the incident on the East China Sea Bridge, I first invited olc, a subsidiary of the German Rhine Group. As the world's second largest offshore wind power construction party, it took 3 weeks and even geological analysis. Later, you had to hire Denmark a2sea. A2sea only took 4 days. Not only did the geological analysis be completed, but the construction plan was also reported."

"It is not difficult to see from this that the Germans' technology is really inferior to Denmark. Fan manufacturing includes Vitas, construction has A2sea, and design has Ramboll. All three masters are above the Germans."

"We used to think that Siemens was the main competitor, and we thought it was too simple. The one who really led the world in this field was actually the Danes."

Luo Jia seemed to be talking to herself. At this moment, he finally raised his head, but did not stop talking.

"According to the 12th Five-Year Plan, offshore wind power will build 30,000mw within five years, and the Huadian ship can only receive 200mw installation tasks every year, which is too far away."

"We felt that there was a chance here, so we carried out this integrated installation ship project. According to our calculations, it should be no problem to receive a single ship's installation task of 1,000mw per year."

"At present, our country seems to have the idea of ​​renting and installing a ship from Europe. I checked the international quotation and it seems to be $150,000 a day. Although our ship is more reasonable and more efficient than the Rhine Group's design, the rent is as long as it is the same as them, and it will be enough to give $150,000."

"You two are experts in the electrical field. Do you think this idea can work?"

Luo Jia finally finished his idea, but no matter how he looked at the two old men, he was very suspicious and thought he had said something wrong.

After a moment of silence, Chief Engineer Ning finally spoke: "Okay, it's worthy of being a straight steel boy group. He is so straightforward. He has stripped down all our pants so mercilessly."

With his body leaning back, Chief Engineer Ning said with a heartbroken feeling, "It's just like you said. At present, we only have the installation ship of Huadian, and the design is not very reasonable."

"Since all the words are up to this point, I'll tell you one more thing."

"Siemens wants to intervene in the installation business in Asia, and the reason is very funny, because they are fan manufacturers and have to undertake after-sales operation and maintenance services. The failure rate in Asia is far higher than that in Europe. At first, they thought it was caused by weather factors on the west coast of the Pacific, but found that it was because of the technical problems of my country's installation company."

"So Siemens is now negotiating with us to sell their installation technology and installation ship to us. I won't mention the price. Anyway, it's more than $150,000 a day."

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

"Since the supercapacitor is easy to use, we will certainly launch green energy smoothly. Before we came here, we were so worried about the engineering ship that we couldn't sleep."

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

"Now that you have already come up with the design, let the Germans go to hell!"

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

After saying that, Chief Engineer Ning took out his cell phone, walked out of Luo Jia's office, and found a secluded place to call.

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

Luo Jia frowned, "It's not a premeditation. The engineering ship is just a small project for us. An Ran told me two days ago that I didn't care much when the engineering ship was designed. After all, Zhenhua and Longyuan are both building, so we are not the first one."

Small project?

Professor Ouyang suddenly felt a little blocked in his chest. The things that were in urgent need of the power industry became an insignificant small project when Luo Jia said.

But thinking about it, Star Technology has done too many shocking projects and designing an installation ship is really nothing to them.

It’s so annoying that people are more popular. Professor Ouyang shook his head helplessly, "Tell you the truth, Long Yuan and Zhenhua’s ships have been stopped because the design is not reasonable enough. If your ship can pass Lao Ning and others’ simulation experiments, it will be equivalent to saving their lives. Otherwise, they will have to wait to be slaughtered by Siemens."

Luo Jia's eyes lit up. He didn't know that the power department was going to buy a ship from Germany.
Chapter completed!
