Chapter 40: Do it yourself, have enough food and clothing
Liquefied natural gas carriers, referred to as LNG ships, are specially used to transport natural gas. The main component of natural gas is methane. To facilitate transportation, it is usually liquefied by freezing at extremely low temperatures (-163C) under normal pressure and compressing the volume to normal temperature.
About one six hundredth of.
This has very high requirements for safety during transportation, so LNG ships are internationally recognized as three high products of high difficulty, high technology and high added value. They are known as the "super refrigerated trucks at sea" and the "crown" of the shipbuilding industry.
"Pearl" and other reputations.
Only a few countries in the world have the ability to produce LNG ships. However, since the transportation cost of LNG ships is indeed very low, less than one-sixth of pipeline transportation, a quarter of the global natural gas is transported by LNG ships.
And the proportion is still increasing year by year.
In recent years, as countries around the world have paid more and more attention to clean energy, the global demand for natural gas has exploded. It is foreseeable that LNG ships will become an emerging market darling in the future.
As a long-established shipbuilding power, South Korea has entered this field very early and quickly formed a monopoly. At present, almost all of the world's new orders for large LNG ships every year are divided up by the three major shipbuilding companies: Daewoo, Hyundai Heavy Industries and Samsung Heavy Industries.
Of course, China's shipping companies are not just for nothing, and we are also an importer of natural gas. The localization of LNG ships is an inevitable requirement to ensure my country's energy security, so the only way to go is to work hard and pursue this path.
In 2008, the Shenhua Shipyard in Shanghai built the world's largest LNG carrier at the time and successfully launched it into service by fully absorbing foreign technology.
This marks the official entry of the Chinese shipbuilding industry into the LNG ship market. However, is the problem solved? In fact, it is not. We have to mention the foreign technology here.
In fact, both Shenhua Shipyard and South Korea's three major shipbuilding companies use the same French company's patented technology to manufacture LNG ships, GTT's membrane ship liquid cargo containment system.
For this reason, the shipbuilding company needs to pay a huge patent licensing fee to GTT Company, up to 5% of the total cost of the entire ship, which includes the material for building the fuel storage tank, Invar Steel.
Generally speaking, most metals or alloys have thermal expansion and contraction properties, and their thermal expansion coefficients are linear. However, Invar steel is different. This material has a very small or even small thermal expansion coefficient in a wide range near room temperature.
tends to zero.
In layman's terms, the volume remains unchanged, which means there will be no thermal expansion or contraction. Therefore, invar steel is an essential material for building large LNG ships to prevent the hull structure from freezing and cracking in ultra-low temperature environments.
Moreover, Yinwa steel is very "delicate". If you touch the 0.7mm thick Yinwa steel with bare hands, it will rust through in 24 hours. It is extremely difficult to manufacture. Of course, it is even more difficult to weld. It is definitely one of the most difficult materials to weld in the world.
.
At present, only the French company GTT can provide Invar steel materials, and there is a proper seller's market. This has formed a monopoly situation in which China and South Korea are struggling to build ships, while the French are just making money.
It feels uncomfortable to have someone's neck stuck. What should I do? It's still like the saying "do it yourself and have enough food and clothing".
Early last year, the localization project of marine invar steel jointly launched by Shenhua Shipyard and Sangang Special Steel Co., Ltd. was officially launched, striving to make my country the second country in the world capable of producing invar steel within 3-4 years after France.
This is definitely good news for my country's shipbuilding industry. At the same time, the Koreans are not idle. Their ideas are even more advanced, that is, to develop a new generation of materials to replace the traditional Invar steel, and this material is the High manganese pure austenitic alloy steel as mentioned by the director.
In fact, this is also a helpless move by the Koreans. Previously, the three major shipbuilding companies had purchased the manufacturing technology of Invar Steel from GTT Company at a high price, but they could not be used in actual production.
The reason is very simple. The nickel content in Invar steel accounts for 36%, and South Korea is short of nickel, so they have to find another way under the pressure of reality. So the question is, why spend a lot of money to buy the patent.
Haha, this is purely an act of trespassing, because at that time, Chinese shipbuilding companies were also applying to purchase patents from GTT Company. This was a real threat to Korean shipbuilding companies. To put it bluntly, it is what I don’t have, and you can’t have it.
The research and development of high manganese steel for ships in South Korea and the localization of our Invar steel are carried out almost simultaneously. Considerable progress has been made so far, but there is still a long way to go before mass production can be achieved.
The biggest purpose of Hyundai Heavy Industries in poaching Zhou Jing's past is to hope that he can preside over the project of mass production of high manganese steel, so Director Quan disclosed the relevant information to Zhou Jing.
Director Quan originally thought that Zhou Jing did not know much about this aspect and was not aware of the importance of this new material. However, he did not know that Zhou Jing's old colleagues were in the Sangang Special Steel localization project team.
Before coming to Korea, Zhou Jing had often heard these things from his old colleagues when we all got together, so he knew what was going on as soon as Director Quan opened his mouth. Even though he looked calm on the face, in fact, he was already like this in his heart.
It's like turning the river upside down.
Zhou Jing was shocked just because Director Quan casually mentioned some data. This new material does not contain nickel, but its strength is three times that of Yinwa Steel. It is estimated that once mass-produced, the material cost will be only half of that of Yinwa Steel.
Less than.
This is not the most important thing. The key is that high manganese steel is less difficult to weld. Its welding cost is estimated to be only one-fifteenth of that of Invar steel. It is comprehensively predicted that if LNG ships are built using new high manganese steel, the economy will be higher than before.
Out a full 4 times.
As a result, China will once again be widened by South Korea in the field of LNG ships. Logically speaking, this has little to do with Zhou Jing himself, but how could Zhou Jing be indifferent to this?
So he took the time to write a detailed report on the matter, and reported it privately during Xu Zhibin's last visit to Seoul. As a result, Xu Zhibin felt a chill on his back after listening to it.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Especially the key figures that appear in the report, Xu Zhibin knows very well what they mean. If all this is true, then San Steel would have spent half a day
The products created by Jin were already lagging behind as soon as they were launched.
Of course, the possibility of the Koreans setting off smoke screens was not ruled out. The matter was so important that Xu Zhibin did not express his position on the spot. He did not even say a word of praise for Zhou Jing. He just said lightly, "I understand."
But judging from the current situation, it is obvious that Zhou Jing’s report has been confirmed, and the corresponding countermeasures are also very simple. The localization project of Yinwa Steel continues to advance, and the research and development of high manganese steel for ships is simultaneously launched. After all, South Korea is short of nickel. We
Not rich either.
It's just that walking on two legs is easier said than done, but relying solely on Sanshan Iron and Steel Group alone would be beyond our capabilities. Therefore, the research and development of high manganese steel is a joint operation with many participants.
In addition to the leader Sangang Group, major domestic steel research and design institutes and more than a dozen large-scale special steel companies have joined in, including both state-owned enterprises and private enterprises. Everyone unites with only one idea, eight words,
"Strive to catch up and strive to surpass."
In fact, this is what makes Director Quan feel scared and worried, so he is full of resentment towards Zhou Jing, especially Zhou Jing who smiles proudly at Director Quan, which makes Director Quan even more angry.
Come everywhere.
"An, yes, do you know how much loss your boy's report has caused to our family? You have to give me an explanation today, otherwise"
"Hey, I'm talking about Director Quan, are you going to act like a hooligan? You said it all on your own initiative, and I didn't trick you in the slightest. Besides," Zhou Jing put away his smile while speaking and came to Director Quan and said seriously,
"Such an important decision depends on my report? Are you kidding me? Then you take me too seriously. As the old saying goes, there is no airtight wall in the world."
Zhou Jing's words are correct. In fact, Director Quan also understands this. No big move in the industry can be so rash, not to mention that it involves so many units. He is just angry that Zhou Jing is obviously going to become the son-in-law of South Korea. Why?
I don’t know if it’s really towards my mother’s family.
"Okay, I'll let you go this time, but you owe me one time after all. I just want to ask you for a favor, so this should be no problem."
"No." Zhou Jing was about to agree, but suddenly his eyes tightened.
This Quan Da Councilor has a criminal record. Could it be that he wants to arrange a blind date with his niece again? Although this matter has not been mentioned for a long time, it may prevent the old man from getting angry for a while.
Crystal has just finished a round of socializing and is waiting to take a look at what that stinky oppa is doing. So far, Zhou Jing's performance is quite satisfactory to her. At least there is no Yingying Yanyan around, only a fat Agassi.
.
However, Fat Agassi seemed to be a little excited, and he had a hint of inciting an accusation, which made Little Crystal couldn't help but sweat for her husband.
The cocktail party has been going on for almost an hour now. Crystal planned to go to the bathroom to touch up her makeup first, and then go to Zhou Jing's side openly for a while.
There is no need to make any cover-up at all. If she communicated with Zhou Jingling throughout the whole process, it would be called a cover-up in the eyes of outsiders. Not long ago, they attended the National Day banquet of the embassy together, and now they are pretending not to know each other? It is simply too fake.
However, before she could take any action, a voice greeted her from behind, "President Su, nice to meet you, we are meeting again."
Jing Shuang turned around and saw Li Fuzhen standing behind her and Su Xia with a smile. To be honest, she had heard a lot about the matter between Sanxing and Rongjin from Zhou Jing, so she didn't feel uncomfortable about Li Fuzhen's appearance.
Accident.
But after she saluted and introduced herself, the three-star eldest princess's response made Crystal freeze on the spot, confused as to what the situation was.
"Anihasay, Li Fuzhen represents nim, and I am krystal."
"Xiu Jingxi, there's no need to be so different. I'm his sibling, so you can just call me Ernie."
