"Mr. Cao, thank you so much this time."

"If it weren't for the help of Nanshan Equipment, Nanshan Engine and Nanshan Special Steel, our large self-propelled cutter suction dredger would definitely not be able to produce so quickly."

Xiang Jiang Hui personally called Cao Yang to express his gratitude.

Just today, Xiang Jianghui already knew that he was going to be promoted to the next level.

This is still the case that the LNG carrier has not been mass-produced, and if the LNG carrier is officially mass-produced later, won't his position within CSSC be on a higher level?

And these results are inseparable from the support of Nanshan Group's subordinate enterprises.

Of course, Cao Yang also needs a shipyard to cooperate with his own company to develop some products.

Otherwise, if you go to build a separate shipyard by yourself, it will be too tossy and time-consuming.

It is better to pull a partner in Yangcheng to work together, the enterprise of the Nanshan system is responsible for the core part, and the other parts are time-consuming and laborious, but the technical difficulty is not so high, and the other party will do it.

Wenchong Shipyard was able to become a partner of the Nanshan system, and to some extent, it can be regarded as their luck.

Xiang Jianghui also knows this in his heart.

"Speaking of which, I have to thank Mr. Xiang for being so bold and daring to use our first mass-produced large-scale gas turbine directly."

"In this regard, our Nanshan Engine is a new player, and many people will have all kinds of worries."

Cao Yang's words were not simply touting each other there.

Nanshan Engine's various gasoline engine and diesel engine technologies are very advanced, and have a large number of applications in the field of domestic passenger cars and trucks.

But gas turbines, especially large gas turbines, are really far behind the world's leading companies.

Of course, it's not that Cao Yang can't come up with world-leading technology, but that there is a process for producing these things.

Gas turbine technology is complex, involving thermodynamics, materials science, mechanical engineering and other fields, requiring a wealth of professional knowledge and experience.

Its manufacturing process involves the processing and assembly of multiple precision parts, requiring high-precision machine tools, measuring equipment, and professional technicians.

In addition, the manufacture of key components such as hot aisle components also requires the use of high-tech processes such as single crystal, directional crystallization, and polycrystalline casting.

Then there's the fact that its high-temperature components operate above the melting point of the metal for long periods of time, while being subjected to extremely high stress and corrosive environments, and the design needs to solve many complex problems such as material selection, structural layout, heat conduction and cooling.

However, the accuracy error requirements of the core components are extremely high, often only a few tens of microns, which puts extremely high demands on the manufacturing and assembly process.

First produce a few relatively low difficulty levels, and then go to the world's top large gas turbines, which is the development direction that Cheng Tao reported to Cao Yang at the beginning.

For example, the large-scale self-propelled cutter suction dredger of Wenchong Shipyard adopts an all-electric drive type and is equipped with three 8000kW main generator sets, which have the characteristics of high efficiency, energy saving and environmental protection.

In addition, the engine produced by Nanshan Engine also has the characteristics of high discharge pressure, long row spacing, excellent wear resistance, etc., and the mud pump motor can change the working mode according to the change of transmission distance, so as to achieve the most effective use of installed power.

It can be said that the performance of Nanshan Engine's first gas turbine is still very good in all aspects.

In the past, it has been working traditional gasoline engines and diesel engines, and now it has begun to enter the field of gas turbines, which can be regarded as a new breakthrough for Nanshan Engine.

"Produced by Nanshan, it must be a high-quality product!"

"Over the years, a very firm understanding has been formed in the industry."

"Nanshan Engine did not disappoint us this time, and the equipment provided by Nanshan Equipment for our ships has made great contributions."

"And Nanshan Special Steel's special steel for our reamer has directly made the performance of our ship reach the first place in the world."

"Since its establishment, Wenchong Shipyard has been working hard, always catching up, and has never won the world's first."

"This time, our large self-propelled cutter suction dredger is now the first in the world."

When Xiang Jianghui said this, the whole person was a little excited.

The world's first is no longer too impactful for the enterprises of the Nanshan system.

After all, they have already won too many world No. 1s.

But for the Wenchong shipyard, the situation is different.

Historically, coming out with a world's No. 1 product is definitely a big deal.

The point is that this thing appeared very timely and made a great contribution in the southern seas.

Xiang Jianghui can imagine that at this year's National Science and Technology Progress Award ceremony, he will definitely have the opportunity to accept the award on stage.

This product can definitely be called a "great power", and it has made important contributions to China in the southern seas.

The further back you look, the more obvious and enormous the credit becomes.

"Mr. Xiang, one plus one is greater than two, we will work together, and we will definitely be able to launch more world-class products in the future."

"We Nanshan Engine will also develop a gas turbine with higher power to serve the new products of Wenchong Shipyard in the future."

Taking this opportunity, Cao Yang chatted with Xiang Jianghui about future cooperation.

Although he already has two fist products in his hands, Xiang Jianghui will definitely not dislike Wenchong Shipyard with too many fist products.

Although China's shipbuilding industry is developing rapidly, its production capacity is already the world's first.

However, the production technology of some special ships still needs to be further improved.

In this regard, Wenchong Shipyard and Nanshan Group definitely have a lot of room for cooperation.

After ending the phone call with Xiang Jianghui, Cao Yang called Cheng Tao to the office.

"Mr. Cheng, if we enter the H-class gas turbine now, how many years do you think it will take to develop it?"

Although Cao Yang often takes various technical teams to improve technology, the group has developed to the present, and it must not rely on him for everything.

What can be done by the team below, he hopes to hand it over to the people below.

Most of the work of this type of gas turbine supplied to Wenchong Shipyard was completed by Cheng Tao and his team.

But if you want to directly upgrade the technology to the H level in one go, the situation is completely different.

If it is distinguished according to the advanced level, the combustion chamber temperature of the E-class gas turbine can reach 1200 degrees, the F-class can reach 1400 degrees, and the H-class temperature can reach 1600 degrees.

In 2000, Siemens proposed a research and development plan for H-class gas turbines, and after years of research and development, testing and commissioning, the world's first H-class gas-steam combined cycle unit was finally put into commercial operation in 2011.

Now it is 2013, and Cao Yang asked Nanshan Engine to follow to develop H-class gas turbines, which is difficult to imagine.

"Mr. Cao, so far there is no F-class gas turbine in China."

"If you want to build an H-class gas turbine, it must be a large heavy-duty gas turbine."

"At present, the only countries in the world that can independently develop heavy-duty gas turbines are the United States, Germany and Dongying."

"The R&D and manufacturing level of heavy-duty gas turbines also largely represents the level of heavy industry in a country."

"In the research and development of heavy-duty gas turbines, we must not only emphasize performance, but also emphasize cost performance, and must be able to really bring better benefits to power plants and other users."

"Our experience in this area is very lacking."

Cheng Tao said with a wry smile.

He didn't expect Cao Yang to put forward such a high goal with him as soon as he came up, and he almost didn't scare him stupid.

Large, heavy-duty gas turbines, does he want to do it?

I definitely want to do it!

But he has no faith now!

"Whether it is the 8000KW gas turbine we are studying now, or the large heavy-duty gas turbine, in fact, the structure is similar."

"The three core components of compressor, burner and turbine, as long as the relevant principles are mastered, there is still hope to continue to improve the size."

Cao Yang's words made Cheng Tao feel that he didn't know how to refute.

If he didn't know that Cao Yang was a very technical person, he would have scolded his mother.

The principle is similar, but the design difficulty and processing difficulty of small gas turbines and large gas turbines are completely different.

"Mr. Cao, large gas turbines have very high requirements for accuracy due to their huge volume and complex structure."

"For example, the crankshaft is one of the core components, and its diameter, shape, trajectory and journal position, size and roundness must meet strict precision standards."

"In contrast, small gas turbines are relatively easy to control accuracy due to their smaller size."

"At the same time, large gas turbines have more stringent requirements for materials and manufacturing processes, and their high-temperature components need to operate above the melting point of the metal for long periods of time, while being subjected to extremely high stress and corrosive environments, which is extremely difficult to design."

"In order to ensure the high temperature resistance, stability and precision of the components, special alloy materials and complex processing technologies are required."

"In the case of small gas turbines, although they work on a similar principle, they have relatively low requirements for materials and processes due to their small size."

"Then there is the large gas turbine because it involves more components and systems, and its system integration and commissioning is also more difficult."

"This requires ensuring that the individual components and systems are coordinated and matched to achieve optimal performance and efficiency."

"Small gas turbines, on the other hand, have relatively low difficulty in system integration and commissioning due to their relatively simple systems."

"If we were to develop an H-class gas turbine now, I would estimate that it would take five to 10 years to produce it."

Cheng Tao gave a relatively pessimistic time data.

At least that's what Cao Yang thinks.

Five to 10 years later, when the gas turbine was developed, and when it was used in power stations or ships, the daylily was cold.

There is no way to reflect the technological advancement of Nanshan engine.

"The higher the grade of the heavy-duty gas turbine, the higher the thermal efficiency, with the single-cycle thermal efficiency of the E-class gas turbine being around 34% and the combined cycle being around 53%."

"The single cycle of the F class is about 38%, and the combined cycle is about 57%."

"And the higher the efficiency, the same energy, will be able to get more electricity, which is a very critical indicator for ships, for power plants, etc."

"Now that the H-class gas turbines of Siemens and General Electric have been mass-produced, we should be able to save a lot of time by combining their product models for development."

Even if the drawings of Siemens and General Electric's H-class gas turbines were made available to everyone, few countries would be able to produce a qualified product.

Even in China, the situation is similar.

However, for Nanshan Engine, for Nanshan Group, the situation is definitely different.

Whether it is the three core components of compressor, burner and turbine, or other supporting parts, Nanshan Group has the strength to challenge.

Especially in the field of materials science, the level of Nanshan carbon fiber and Nanshan special steel is also leading in the world.

Cao Yang didn't believe that he directly gave out the relevant drawings and data of the Siemens SGT5-8000H super gas turbine, and it would take so long for Nanshan Engine to copy the operation.

"Mr. Cao, Siemens' H-class gas turbine has indeed been mass-produced, but General Electric is only announcing relevant data and prototypes, and the real mass production will be next year."

"And when we take out its data and take a brief look at it, we can feel the difficulty."

"The Siemens SGT5-8000H super gas turbine weighs 390 tons, which is equivalent to a fully fueled Airbus A380."

"It is 13.1 meters long, 4.9 meters wide and 4.9 meters high, and has a power of 375MW, which is equivalent to the combined power of 13 Airbus A380 engines, or nearly twice the total power of the Nimitz carrier."

"GE's H-class gas turbines are even more powerful, reaching a staggering 1,300 megawatts, which is equivalent to the power generation capacity of a large nuclear power plant."

"It is very difficult to develop such a large model of product, even if you want to learn from it."

Cheng Tao felt that he still needed to explain the problem clearly.

Otherwise, if Nanshan Engine really established an H-class gas turbine project, but it couldn't come out with the product for a long time, he would be under great pressure.

"If we can get the main drawing data of the Siemens SGT5-8000H super gas turbine and carry out further design development on this basis, will it be possible to produce the first prototype in two years?"

The heavy-duty gas turbine is definitely a big tool in the country, and Cao Yang still hopes to use it as the fist product of Nanshan Engine in the future.

The production of automobile engines, no matter how good the production is, is mainly used in the civilian field.

But the situation with gas turbines is different.

They can be used not only in power plants, but also on large ships.

What ship needs a large heavy gas turbine?

"Mr. Cao, Siemens' confidentiality work is very good, even if we can obtain part of the drawing data through various methods such as digging people and buying, it will definitely be incomplete."

"Although this can improve our R&D speed, it is estimated that we will not even be able to finalize the final product drawings within two years."

"Not to mention the follow-up trial production of parts."

"Even if we want to produce such heavy-duty gas turbines, we need to invest in a lot of specialized production lines."

"For example, large-scale forging presses and large-scale CNC machine tools need to be developed synchronously by Nanshan equipment."

"Even under a more ideal scenario, I think it will take three or four years to produce a prototype, and after five years, it will officially enter large-scale mass production."

Cheng Tao felt that what he said was already more radical.

He didn't dare to say that it was too conservative, and Cao Yang would definitely be dissatisfied with it.

"Whether it's two years or three years, start the project first."

"There are actually a lot of technical talents engaged in gas turbines in China, and the United States, Germany and Dongying can also poach some people back."

"Even in the countries where Polar Bear once joined, there are some experts in steam turbines, and we can find a way to invite them."

"Eventually, I hope that in three years' time, the large heavy-duty gas turbine belonging to Nanshan Engine will be able to enter mass production!"

At this time, Cao Yang will not let Cheng Tao determine the schedule.

If you don't put some pressure on the people below, everyone's motivation to work is not so high.

Taking this opportunity, it is also a good choice for Nanshan Equipment to completely enter the field of heavy industry.

Feeling Cao Yang's strong attitude, Cheng Tao had no choice but to agree.

After knowing that Nanshan Engine began to set up a project to build a heavy-duty gas turbine, Pan Jun immediately came to Cao Yang to exchange some future development strategies.

"Mr. Cao, there are too few excellent companies like Nanshan Group in China."

"The technical level of our warships and the production level of aero engines still need to be continuously improved."

"If Nanshan Group can deeply participate in these projects, it will definitely be very beneficial for Huaxia's technological breakthroughs in related fields."

Pan Jun now has great confidence in Nanshan Group.

In his opinion, as long as Nanshan Group starts to work on a certain project, it will be able to succeed in the end.

This is true for both heavy-duty gas turbines and aero engines.

So what he has to do is to persuade Cao Yang to set up more new projects, so that Huaxia can catch up with the world's advanced level in more fields.

"Representative Pan, as soon as you say that, I will be under a lot of pressure."

"Countless brother companies are expected to have opinions on us."

Cao Yang laughed and made a joke.

Sometimes you can't be humble, but sometimes you have to be humble.

"Mr. Cao, Nanshan Engine is the strongest engine company in China, whether it is in gasoline engine or diesel engine technology, it is very powerful."

"Now in the field of gas turbines, Nanshan engine has also begun to exert force, and it will definitely be very worth looking forward to in the future."

"In that case, let's just build a large aero engine as well."

"When the time comes, whether it is a new fighter jet or a large transport aircraft, it can be used."

"Even the large drones on the side of Daystar Technology can be considered for use."

"If you can make a product like a large transport plane into a drone, that deterrent effect is also very amazing."

Pan Jun is now thinking of ways to let Cao Yang do more projects.

Especially in terms of aero engines, domestic related enterprises have not been satisfied.

Even Pan Jun sometimes wants to curse.

At this time, his greatest hope is to put it on the side of Nanshan Group.

"We are already starting to develop aero engines, but it's hard to say when we will be able to develop the kind of products that you said can be used on large transport aircraft."

Nothing has come out, so there's no need to talk so much.

Now you just say that you can get an advanced aero engine this year, and people have to be willing to believe it.

At the end of the day, it's about getting the product out as soon as possible.

"Daystar Technology is already engaged in large-scale transport helicopter projects, and it must be no problem to engage in the engines on large transport aircraft, right?"

Cao Yang didn't give himself a quasi-letter, and Pan Jun was still a little unwilling.

"After we get out the main UAV and large transport helicopter projects at hand this year, we will focus on aero engines next year."

Cao Yang chatted with Pan Jun for a while, and finally gave a preliminary plan.

In this regard, Pan Jun can be regarded as satisfied.

There is no shortage of material for the next report to the relevant departments.

……

"President, we inquired, Nanshan Group is only initially involved in the shipbuilding industry, producing some gas turbines and related components, and its influence in the industry is still relatively small."

As the general manager of Samsung Huaxia, Lee Jae-lim has to collect relevant information and report to the headquarters for all the businesses involved in Samsung Group.

During this time, the "island-building artifact" produced by Wenchong Shipyard was very popular on the Chinese Internet, and a lot of related information was picked up.

For example, the gas turbine of this ship is produced by Nanshan Engine, and the main equipment in it is produced by Nanshan Equipment, and the related steel is mainly provided by Nanshan Special Steel.

After this information was exposed, Samsung Huaxia immediately reported it as an important project within the company.

Samsung Huaxia is a little sad now, and these are closely related to Nanshan Group.

Now seeing that Samsung Shipbuilding may also face the threat of Nanshan Group, Li Zailin must ask the headquarters to make it clear in advance, so as not to let himself be blamed when he gets it.

Don't look at him as the general manager of Samsung Huaxia, but his status in the headquarters of Samsung Group is not particularly high.

"Is Nanshan Group's ambition so big?"

Li Zairong asked rhetorically in a rather unhappy mood.

Over the years, he has not suffered less losses from Nanshan Group, and has left some psychological shadows.

"They are now the largest industrial enterprises in Huaxia, and the "Made in China 2023" promulgated by relevant departments in China is based on many concepts and ideas put forward by their group."

"In this case, the status of Nanshan Group in China has become more and more similar to the status of Samsung Group in Goryeo."

"In time, Nanshan Group's influence in China will reach a height that many people can't imagine."

Lee Jae-lim gave his own judgment very affirmatively.

Li Zairong was very uncomfortable when he heard this.

When will a Chinese company be able to compare with Samsung Group?

Samsung Group!

It was a pillar of the Korean economy, a company that the people of Korea could not avoid from birth to death.

Now it is actually facing the challenge of Chinese enterprises.

"They are so capable of making trouble, the United States and other countries should have a very big opinion on the Nanshan Group, right?"

"The other party's performance in the 'island-making artifact' this time has also aroused the jealousy of many peers."

"I think it's okay to pay attention to their situation for the time being, and there is no need to worry too much in the shipbuilding field."

"Instead of worrying about them, it's better to worry about the situation in China Shipbuilding Industry."

Li Zairong thought about it and felt that the main competition that Samsung Heavy Industries is facing now actually comes from Dongying enterprises such as Mitsubishi Heavy Industries, rather than Huaxia enterprises.

Let him put the threat of Huaxia enterprises first, unless Nanshan Group's performance in the shipbuilding field can be like Honor Technology's performance in mobile phones.

Otherwise, he still wouldn't pay too much attention to the Nanshan Group.

In this regard, Li Zailin is also very helpless.
