? “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, I wouldn’t tell you if I didn’t pass the simulation test. As we expected, all the performances have met expectations.”
Luo Jia breathed a sigh of relief, “Although the engineering ship is a small project for us, it is very happy to be able to complete it smoothly.”
“Professor Ouyang will come over the day after tomorrow and 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 of them 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.
Luo Jia would of course welcome him personally.
Fortunately, Professor Ouyang and Chief Engineer Ning are both academics, they have no airs and are easier to get along with.
Luo Jia invited them to his office, asked the administration department to serve tea and water, and took good care of 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 supercapacitor was sent to the grid for testing. It should be that the grid has some opinion on our capacitor.” 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 100%. Six!”
“At the beginning, we thought that if the self-discharge loss rate could be 20%, it would be acceptable, but the result was only 6%! It was beyond imagination, completely beyond imagination!”
Capacitors naturally have the defect of self-discharge.
After all, everything has pros and cons. Capacitors can be 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 Xingchen 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 cost performance is terrible.
So scientific research is difficult, and technology application is more difficult than scientific research. 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, “It seems that we are going the right way by taking the high-density carbon material. The price is not high, and the grid can be satisfied.”
“I don’t know, what is the cost of energy storage after grid accounting? Is there any value for large-scale use of supercapacitors?”
Ning Zeping said happily, “Cost is used in different scenarios, and the final results are also different.”
“But according to our estimation, it should be about 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. I would like to thank you Star Technology for your hard work.”
Luo Jia hurriedly said modestly, “Don’t say that, a good person like you will definitely live a long life.”
“Since you two are here today, I have something else here that I want to show you.”
After finishing 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 pilings on the seabed, they are combining subsea platforms.”
“This 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 is too low, so he concentrated the strength of the hardware department and redesigned this integrated installation ship, which is more efficient than It has improved a lot in the past.
The two elders showed unbelievable expressions. After a long silence, they sat down again, and Ning Zepinghu asked: “How do you know that we lack this thing?”
Luo Jia said with a smile: “This shouldn’t be a secret, right?”
“At present, only Huadian has an installation ship 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 repairing 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. It can be explained.”
Luo Jia and An Ran both 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 hired. As the world’s second largest offshore wind power construction company, OLC took three weeks without even doing a geological analysis. After you came out, you had to invite A2Sea from Denmark, and A2Sea only took 4 days, not only finished the geological analysis, but also issued a report on the construction plan.”
“It is not difficult to see from this that the technology of the Germans is really not as good as that of Denmark. Vitas is in the wind turbine manufacturing, A2Sea in the construction, and Ramboll in the design. The three masters are all above the Germans.”
“We used to think Siemens as our main competitor. It was too simple. The Danes are actually 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 will be built within five years, and Huadian’s ship can also undertake the installation task of 200M per year, which is too far behind.”
“We thought there was an opportunity here, so we started this integrated installation ship project. According to our calculations, it should be easy for a single ship to receive 1000M 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 in design and higher in efficiency than the Rheinland Group, but As long as the rent is the same as theirs, it will be 150,000 U.S. dollars.”
“You two are experts in the electrical field, do you think my idea can be realized?”
Luo Jia finally finished talking about his idea, but no matter how he looked at the expressions of the two old people, he was very suspicious, thinking that he had said something wrong.
After a moment of silence, Chief Engineer Ning finally said, “Well, as expected of the Iron and Steel Straight Boys, they are so upright, so ruthless, they took our pants off.”
Leaning back, Chief Engineer Ning said sadly, “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 wanted 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. Yes, but it turned out that it was because of a problem with the technology of our installation company.”
“So Siemens is now negotiating with us to sell their installation technology and installation boat to us. I won’t talk about the price, anyway, it is 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 were so worried about engineering ships that we couldn’t sleep.”
“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!”
“Wait a moment, I’m going to call back and ask them not to sign the contract.”
After that, 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. Two days ago, An Ran told me that when the design of the engineering ship was completed ~Soverse.com~ I didn’t care much, after all Both Zhenhua and Longyuan are making it, and we are not the first.”
Small projects?
Professor Ouyang suddenly felt a little tight in his chest. The urgently needed things in the power industry turned out to be insignificant small items in Luo Jia’s mouth.
But thinking 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 angry 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 ship can pass Lao Ning’s ship The simulation experiment 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. After a long time, he made a mistake and cut off the German.
