Rebirth 99 to become a car giant.

"Mr. Cao, I really want to thank you so much this time."

“If it weren’t for the help of companies such as Nanshan Equipment, Nanshan Engine and Nanshan Special Steel, our large self-propelled cutter suction dredger would definitely not have been able to be produced so quickly.”

Xiang Jianghui personally called Cao Yang to express his gratitude.

Just today, Xiang Jianghui already knew that he was going to level up.

This is still the case when LNG carriers have not been mass-produced. If LNG carriers are officially mass-produced later, won't his status within CSSC be even higher?

These results are inseparable from the support of Nanshan Group's affiliated companies.

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

Otherwise, it would be too much trouble and time-consuming to build a shipyard by yourself.

It is better to bring together a partner in Yangcheng to work together. The Nanshan-based company is responsible for the core parts, and the other parts that are time-consuming and labor-intensive but are not so technically difficult can be left to the other party.

To a certain extent, Wenchong Shipyard is lucky to be able to become a partner of the Nanshan Group.

Xiang Jianghui also knew this well.

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

"In this regard, our Nanshan Engine is considered a new player in the game, and many people have various worries."

Cao Yang's words were not simply to compliment each other.

Nanshan Engine's various gasoline and diesel engine technologies are very advanced and are widely used in the domestic passenger car and truck fields.

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 there is a process for producing these things.

Gas turbine technology is complex and involves multiple fields such as thermodynamics, materials science, and machinery manufacturing, requiring a wealth of professional knowledge and experience accumulation.

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 manufacturing of key components such as hot channel components also requires the use of high-tech processes such as single crystal, directional crystallization, and polycrystalline casting.

In addition, its high-temperature components operate above the melting point of metal for a long time and are subjected to extremely high stress and corrosive environments. Many complex issues such as material selection, structural layout, heat conduction and cooling need to be solved during design.

The precision error of core components is extremely high, usually only tens of microns, which places extremely high demands on the manufacturing and assembly process.

First produce a few models with relatively low difficulty levels, and then move on to the world's top large-scale gas turbines. This is the development direction Cheng Tao originally reported to Cao Yang.

For example, Wenchong Shipyard's large-scale self-propelled cutter suction dredger uses an all-electric drive engine and is equipped with three 3kW main generator sets, which is highly efficient, energy-saving, and environmentally friendly.

In addition, this engine produced by Nanshan Engine also has the characteristics of high discharge pressure, long discharge distance, and excellent wear resistance. The mud pump motor can change the working mode according to changes in transmission distance, thereby achieving the most effective use of installed power.

It can be said that Nanshan Engine’s first gas turbine has excellent performance in all aspects.

In the past, we have been working on traditional gasoline engines and diesel engines, but now we are entering the field of gas turbines. This can be regarded as a new breakthrough for Nanshan engines.

“Produced by Nanshan, it must be a top 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 various equipment provided by Nanshan Equipment for our ships have made great contributions."

"Nanshan Special Steel specializes in special steel for our reamers, which directly makes the performance of our ship reach the first place in the world."

"Since its establishment, Wenchong Shipyard has been working hard and catching up. It has never ranked first in the world."

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

When Xiang Jiang Hui said this, he felt a little excited.

Being No. 1 in the world no longer has much impact on companies in the Nanshan system.

After all, they have won too many world firsts.

But for Wenchong Shipyard, the situation is different.

To come up with a product that is the first in the world in history is definitely a great achievement.

The key is that this thing appeared very timely and made great achievements in the southern sea area.

Xiang Jianghui could imagine that at this year's National Science and Technology Progress Award Ceremony, he would definitely have the opportunity to go on stage to receive the award.

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

The further we look back, the more obvious and huge this contribution becomes.

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

"We at Nanshan Engine will also develop more powerful gas turbines to serve Wenchong Shipyard's new products in the future."

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

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

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

However, the production technology of some special ships still needs further improvement.

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

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

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

Although Cao Yang often leads various technical teams to improve technology, the group has developed to this point and certainly cannot rely on him for everything.

He hopes to leave things to the people below him that can be done by the team below.

Cheng Tao and his team completed most of the work for this model of gas turbine supplied to Wenchong Shipyard.

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

If distinguished by advanced levels, the combustion chamber temperature of E-level gas turbines can reach 1200 degrees, F-level can reach 1400 degrees, and H-level temperatures can reach 1600 degrees.

Siemens proposed a research and development plan for H-class gas turbines in 2000. After years of R&D, testing and debugging, it finally completed commercial operation of the world's first H-class gas-steam combined cycle unit in 2011.

Now in 2013, Cao Yang asked Nanshan Engine to follow suit in developing H-class gas turbines. One can imagine the difficulty.

"Mr. Cao, China has not even developed an F-class gas turbine so far."
