The Quan Diesel Combined Power Plant was developed for military use. It was benchmarked against the relevant parameters of the U.S. Navy from the beginning, and would only be higher than those of the Chinese Navy.

This brings up a problem.

To be converted to civilian use, the performance is excessive.

We have to find ways to reduce performance and cost, so that we can compete with mature Western products internationally.

In this area, Academician Yang Zhiqian has the richest experience, because he has been involved in the research and development of almost every domestic marine diesel engine.

The original Jichai Power Plant had a high-horsepower diesel engine, which was mainly used in power plants, hydropower stations, etc. It was the most powerful diesel engine in the Jichai Power Plant at that time. In the original project team, Yang Zhiqian, who had not yet become an academician, was the chief researcher.

Quan-diesel combined power plant electric propulsion system for ships, this is a golden combination.

Yang Zhiqian decided to bring another group of students, which meant that he had to form a young team to cooperate with Jichai General Factory and Chunfeng Academy of Science. This meant that the plan of some people in the Chen family to control Shipbuilding Industry against Yao Yuan went bankrupt.

.

In fact, Zhong Weiguo has already told Yao Yuan on the phone that these things will not have an impact on him, and someone will naturally deal with the short-sighted Chen Peng.

Yang Zhiqian smiled and said, "Xiao Yao, can you talk to me about the electric propulsion system? Even your old age doesn't know much about this black technology."

"This is the black technology of old Europe." Yao Yuan said with a smile, "Ship electric propulsion technology is one of the specialty technologies of old Europe. The most powerful one is Germany. The representative companies are Siemens and e-ms, as well as

A more powerful company is the Swiss company ABB."

He decided to tell Yang Zhiqian how the Chunfeng Academy of Sciences' Chuarbo electric propulsion technology came about. This was confidential information of the Dongfeng Group.

"Among them, Swiss ABB has the strongest technical strength. Their main product is a pod-type electric thruster. The propeller can rotate in all directions, which is very powerful. Of course, it is also very expensive. Their products are mainly high-end and are loaded on yachts.

On cruise ships, high-speed ferries and other high-value-added ships, cargo ships generally do not use this kind of propeller, because it is too expensive."

Yao Yuan paused and said, "Germany's Siemens is more in line with our needs. It is not easy to increase the power of pod-type electric thrusters. Germany's Siemens adopts a traditional approach. Their products are widely used in LNG ships."

on large-tonnage ships with high added value.”

"Our technology comes from ABB and Siemens. By combining their technical advantages and disadvantages and combining it with our own actual situation, we came up with the current electric propulsion system..."

Yang Zhiqian asked curiously, "Introducing technology? Or introducing product research and development?"

Yao Yuan shook his head slightly and said, "They won't sell it. The companies mentioned above are OEMs, and their suppliers are very critical. They are basically distributed in the four countries of France, Germany, Switzerland, and Italy. These

Suppliers basically have their own unique technology patents, all of which are black technologies accumulated from old Europe."

"We can talk to one or several European companies about introducing technology, and there should be a 20-30% chance of it. But if we want to get a full set of technology, we must negotiate with all the OEMs and suppliers. Not to mention other things, the countries where they are located will

The government will simply stop it.”

"If you can't get a full set of technology, you can only buy their parts and assemble them. In the end, you still haven't formed your own set of technology, which is of little significance. I don't want to waste time on reverse research, so I use other special methods and channels.

, it took more than a year and a lot of money to obtain the ship electric propulsion technology from ABB and Siemens..."

Yang Zhiqian understood, and he wisely stopped asking, because it already involved the secrets of Dongfeng Group. In a business war, it is normal for all parties involved to use all their efforts to find out the opponent's intelligence and secrets, and commercial espionage is not a new profession.

.

"There is also a durability issue with pod-type electric thrusters. The Navy may not like this kind of fancy thrusters. I have asked people to do market research. High value-added ships that require high speed and flexibility are the most popular ones.

The domestic market for high-speed ferries is still blank," Yao Yuan said.

A big difference between Academician Yang Zhiqian and Academician Yang Qi is that the former has stronger application thinking and market thinking. To put it bluntly, Academician Yang Qi is focused on reaching the peak of technology, while Academician Yang Zhiqian takes into account market benefits and focuses on the impact on social and economic development.

.

Yao Yuan has found a suitable partner for the Quanchai Combined Power Plant pod-type electric propulsion system, which makes Yang Zhiqian increasingly feel that the decision to cooperate with Jichai General Plant and Chunfeng Academy of Science is very correct.

The cross-sea route from Yantai to Dalian is the busiest passenger route in China, crossing the Bohai Sea from south to north, with a straight-line distance of 160 kilometers.

The current maximum speed of ferries does not exceed 12 knots, which is about 22.5 kilometers per hour, and the voyage takes at least 7 hours. In fact, including the time for berthing and preparation, it basically starts in the morning and arrives in the evening.

This speed is too slow.

Twenty years ago, there were already high-speed ferries in the English Channel with a maximum speed of 30 knots.

Yantai to Dalian and Weihai to Dalian are the shortest choke sea passages between Shandong and the entire eastern, southeastern and northeastern regions. If you do not take these two ferry routes, you must enter Liaoning via Hebei and Tianjin to reach your destination.

Taking Shenyang as an example, you need to walk a full 1,000 kilometers more.

For trucks operating in transportation, it means profits turn into losses.

After briefly talking about the current situation of Bohai ferries, Yao Yuan said, "If a high-speed ferry is used, such as the Endeavor, with a maximum speed of 26 knots, the journey from Yantai to Dalian will only take more than 3 hours, which is shortened by more than half."

"This is of great significance for accelerating the logistics efficiency in the Northeast, Shandong Peninsula and even the eastern region. Headwind Logistics, a subsidiary of Dongfeng Group, has conducted dozens of experiments. Taking the freight route from Jinan to Dalian as an example, if the sea crossing time can be shortened by half,

They can save two-thirds of their transportation costs and double their efficiency. With this input and output, the transportation company's profit can be doubled."

"The social benefits are even greater. During the War of Liberation, a large number of people from Shandong entered the country, and people-to-people exchanges between the two places were very frequent. If we use the high-speed ferry, Yantai people can go to their relatives' houses in Dalian for lunch if they leave in the morning and have lunch at noon. That's it.

We can still get back to Yantai before dark."

Smiling, Yao Yuan said, "It has greatly shortened the distance between the people of the two places and increased the economic closeness between the Luda area and Shandong area. It is of great significance."

Yang Zhiqian couldn't help but applaud. He has been working in Harbin for a long time. When he needs to go south for work reasons, he always takes a train to Shanghai and other industrial towns in the eastern region via Beijing, Hebei, and Tianjin. Each trip takes several days.

If there is a high-speed ferry, taking a car will shorten the time by at least half compared to a train.

Of course, he has already reached the level where he can fly.

They talked until late at night, and Yang Zhiqian went back to rest with unfinished content. On the way back, Yao Yuan exchanged views on the development of Jichai Diesel General Plant and unified their thinking.

In the next two days, after Yang Zhiqian inspected Jichai General Factory, he took his disciples back home. This time he will form a new team when he returns.

Zhu Yingjie's team and Yao Yuan took a special plane back to Nangang. This was because after learning that Xiangxiang Shipbuilding had received a ship order of 5 million tons, Zhu Yingjie almost died of a heart attack on the spot and insisted on going to the site to see Xiangxiang Shipbuilding's two new models.

The situation of shipbuilding technology.

It can greatly shorten the construction period of civilian ships, and of course it can also shorten the construction period of military ships!

It took three years to build the 112th ship. If we follow the direction of shipbuilding, after using the new shipbuilding method, it only takes one year to launch it.

This is a revolutionary technological advancement in the shipbuilding industry!

No one knows the far-reaching impact of the new shipbuilding method better than Zhu Yingjie, except of course Yao Yuan. The ship order of 5 million tons is already very clear.

Yao Yuan dropped off international shipowners and representatives of major shipyards in the provincial capital. When he came back to Nangang, the provincial government clearly arranged the inspection route for international shipowners and representatives of major shipyards.

I have just arrived in Nangang and settled down for a day.

Many shipowners and representatives of major shipyards are impatient with the arrangements of the provincial government, but they are reluctant to give up the opportunity to see the two major technologies of giant block construction method and flat-surface shipbuilding method with their own eyes, so they can only follow the inspection arranged by the provincial government.

The route went down.

Not to mention, the work of relevant functional departments of the provincial government is effective. Hyundai Heavy Industries intends to invest in building a segmented construction plant in the provincial capital, while Sumitomo Heavy Machinery of Japan is keenly aware of the extremely huge vertical elevator market in mainland China...

As long as they are foreign-funded companies that want to make money, they will not turn a blind eye to the huge Chinese market, its potential and the current speed of economic development.

Therefore, even though we arrived at Nangang nearly five days late, there were actually only a few representatives of the shipowners and shipyards who had complaints in their hearts.

Directional Shipbuilding planned a grand welcome ceremony, because not only foreign customers and colleagues came to visit, but also provincial leaders and big bosses in the domestic shipbuilding industry.

Shipbuilding Industry and Shipbuilding Industry, the two leading domestic shipbuilding state-owned enterprises, are both led by deputy ministerial-level general managers. Several directors of the department-level shipyards affiliated to these two giants have come. It can be said that the backbone domestic shipyards are basically all

coming.

Yao Yuan noticed that Chen Peng, Wang Jianqi, Zheng Lin, Sun Yimin, Hu Bo and others also came. Among the shipbuilding industry team, especially Wang Jianqi and Zheng Lin, it seemed that they did not return to the unit, but directly

Came to Nangang.

No one will turn a blind eye to orders for ships with a displacement of 5 million.

There are even several private shipyards from Fujian Province. They are only small and medium-sized. They are said to be private shipyards, but in fact they are private shipyards under the collective ownership of townships. Those who can get the shipbuilding inspection opportunity from the other side are mostly profitable.

Yes, capable of building thousand-ton ships.

Adding experts from relevant domestic research institutions, as well as the personnel responsible for accompanying and receiving guests from the Nangang City Government, the number of people to be received this time is actually as many as 500, which has brought a lot of challenges to Fangxiang Shipbuilding.

Huge reception pressure.

Fortunately, the Nangang City Government was very proactive. They had a functional department dedicated to reception, and sent an experienced office director to bring the heads of several departments. The instructions were issued in an orderly manner, and it took only two days to complete the entire reception.

The reception activities have been arranged.

Chen Zuer, deputy director of the Chunfeng Group's board of directors office and director of the external relations department, and Li Jiacheng, deputy director of the external relations department, both of whom have excellent image skills, served as tour guides for all the guests. Chen Zuer is proficient in English and Japanese, and Li Jiacheng is proficient in English and German.

He has many years of attainments in French and French.

Chen Zuer introduced in Chinese, and Li Jiacheng used three language translators to explain when necessary. There was no simultaneous translation. Guests from abroad had their own translators. For the few who did not, the provincial foreign affairs department would also provide them with one.

translate.

The Fangxiang Lingang Industrial Park covers a very large area. Most of the southern area is the Fangxiang Shipbuilding factory area. The coastline alone is five kilometers long, so it is very unrealistic to visit on foot.

Fortunately, there are sightseeing buses, and the important guests are gathered on the top floor of the two sightseeing buses in front, and they take a tour. There are only a few dozen important guests, and two sightseeing buses are enough. Others follow in other vehicles, so naturally

The person who has the direction to build the ship will be responsible for the introduction.

Fangfang Lingang Industrial Park is positioned as a high value-added port industrial zone. There are two major industrial entities in the park, Fangfang Machinery and Fangfang Shipbuilding. The latter has already opened a shipbuilding base on the East Coast Island, so the factory here will not

Expand again.

In fact, the current area is large enough.

What everyone wanted to see was the construction site of the giant block shipbuilding method, so they didn’t pay much attention to Chen Zuer’s other introductions about directional shipbuilding.

Yao Yuan only cares about the shipowners. These are all financial backers and parties. As long as they are happy and as long as they readily make advance payments, he can satisfy everything.
