Chapter 242 The 400,000-ton shipyard cost no money

"Brother Tao, I'll go back to Huating by myself. If you want to go to Bincheng Diesel Engine Factory, then go." In the room, the lights were dim and the atmosphere was good. Zhao Ling put her head into Qin Tao's chest and said to him .

It was already evening, and the meal lasted from noon to evening before the guests dispersed, and it was time for Qin Tao and Zhao Ling to go back. After all, they should go to work on the third day of the Lunar New Year.

Qin Tao immediately shook his head: "That's not possible. Since we came together, we have to go together. This is important."

“But don’t you want to go and see the experts from the island country?” Zhao Ling said: “Let’s not talk about superstition. Since you want to go and see it, of course I can’t drag you down.”

"The experts are coming, but that doesn't mean they will definitely come tomorrow. Moreover, they won't leave immediately after they come. They have to conduct an inspection there before they can draw up a detailed investigation report. Even if it doesn't take ten and a half days, If you are only 1 month old, you have to stay for a week, so why should I be in a hurry?"

Creak, at this moment, the door opened.

Zhao Ling quickly moved her head away from Qin Tao, then looked at the door and found that her father had come in.

"Dad, really, why don't you know how to knock on the door first and then come in?" Zhao Ling glanced at her father dissatisfied: "Your daughter is already married, so she has privacy, okay?"

"Oh, oh." Wu Shengli quickly agreed, but still walked inside, and then sat on the chair opposite the bed: "Taozi, there were many people just now, so I didn't say something. I heard that you were over there in Huating. , mentioned our new frigate plan to them?"

Qin Tao picked up his wife at that time and mentioned it in passing. Who would have thought that the news would reach his father-in-law so quickly. I really don’t know who told him. Is there an intelligence officer there?

“Yes, but we should go.” Qin Tao said, “Xiao Ling should go to work tomorrow.”

"I've already said hello to them and asked Xiaoling for a day off. You guys have come all the way, so you have to stay at home for one night and leave during the day tomorrow," Wu Shengli said.

"Dad, how could you do this?" Zhao Ling was anxious: "I can't be special, what will other people think of me? Do you know?"

Zhao Ling quit her job, she is married, and her father is still interfering in her private affairs. What's going on?

 Zhao Ling was very dissatisfied.

"I told the other side that you are going to attend a meeting of the naval department and it is business." Wu Shengli said.

"Meeting, what kind of meeting?" Zhao Ling still looked at her father angrily: "How can you lie?"

“Of course I didn’t lie.” Wu Shengli said: “The theme of this meeting is the technical demonstration of the navy’s new generation frigates.”

"Tch." Zhao Ling glanced at him: "Where is the meeting, and who is participating in the meeting?"

“The location is at our house. There are three people attending the meeting!”

Qin Tao looked at Wu Shengli's look, a little funny, hey, why did he say that? However, since my father-in-law is so anxious, I might as well just say all the unfinished things.

“Okay, let’s go to the study room, Dad, I need to use your desk and draw a design drawing.” Qin Tao said.

 “Okay, let’s go to the study!” Wu Shengli put his hands behind his back and walked out, looking like a leader.

Qin Tao glanced at Zhao Ling: "Let's go. You can go during the day tomorrow. You can rest tonight."

"Humph, you still need to rest? This meeting will last until dawn." Although Zhao Ling complained, she still walked out with Qin Tao and entered her father's study. Wu Shengli had already put away the drawings and drawing tools.

“Dad, you can first listen to Xiaoling tell you about the development progress of the Hongqi-16. I’ll draw a picture here first.”

At this time, Zhao Ling has put on a new expression. Since she has to report on her work, she should be more serious.

Zhao Ling explained non-stop, introducing everything from the guidance principles and methods, to the internal structure, and the progress of imitation.

 After Zhao Ling finished speaking, Qin Tao's drawings were also drawn. It was just a sketch anyway, and it didn't need to be so detailed.

“The superstructure is all tilted inward, similar to a missile boat. Is this also considering the requirements of stealth performance?” After seeing the design drawing, Wu Shengli was immediately curious.

Over the years, domestic shipbuilding technology has continued to develop. In the early 051, there was no consideration of stealth at all. From the outside, various masts, missile launchers, antennas, etc. were everywhere. By the time 052 arrived, it looked like It's a little simpler, 051C goes a step further, and when we look at the design drawing of the new frigate in front of us, the sides of the ship have been completely wrapped, and the overall shape is very simple.

"Yes, stealth is a trend, and all countries are pursuing it. We must not fall behind. Even if we reduce our four-thousand-ton frigate to two-thousand-ton, the radar reflection area of ​​the one-thousand-ton frigate will be good. .”

Wu Shengli nodded: "This design looks very good. Are the anti-aircraft missiles deployed in the front?"

 The first thing to look at is the appearance, and the second thing is to look at the location of the anti-aircraft missiles. After all, what the navy lacks most is its air defense capability.

"That's right, deploying it in front, behind the naval gun, is the most suitable position. We now use the wheel launch method and arrange four groups of eight-unit launch tubes. In this way, we have thirty-two spare bombs, which is considered It's enough. When our thermal emission technology matures in the future, this space can be reduced."

Qin Tao is down-to-earth. It is unrealistic to engage in thermal launch now. Let’s use cold launch first. This will make the launch silo a bit large and crowded, which will be convenient later.

 At least it is much stronger than Haihongqi 7!

“Let’s look at the rear. There is a roof radar on the mast, and a separate large chimney behind it.” Qin Tao continued.

"There is only one big chimney like this? What power does it use?" Wu Shengli became concerned.

 “Of course it’s a diesel engine.”

Although the displacement is not much lower than that of the 052, it is a frigate after all, and there is no need to pursue such a high speed. There is no need for tall things like gas turbines, a simple diesel engine will do.

“We only need four diesel engines, with a total power output of 20,000 to 30,000 horsepower. We don’t count on the 052’s 50,000 to 60,000 horsepower.”

052 uses two LM2500 gas turbines, which can output 55,000 horsepower, pushing this warship to more than 30 knots. For a frigate, this kind of power is quite a luxury. As for the frigate, 20,000 to 30,000 horsepower is enough, and it can run 26 or 7 knots.

 But here Wu Shengli still had to frown: "Four engines, outputting 20,000 to 30,000 horsepower? Isn't this a bit difficult?"

Even the most technologically advanced Bincheng Shipyard does not have such an advanced engine with a single output of seven or eight thousand horsepower!

The country has always been troubled by heart problems. It wants to build advanced third-generation tanks, but there is no suitable high-power tank engine. It wants to build advanced third-generation fighters, but there is no advanced aeroengine. The same is true for ships. Although they can be produced on hand, they have already been Falling behind.

Qin Tao nodded: "Yes, none of the diesel engines we can produce at hand can reach this level. However, as long as we modify the diesel engines we imported from France and use STC technology, we can achieve a breakthrough in engine performance. It meets our needs.”

“French diesel engine, improved?” Wu Shengli was still a little curious: “Can we make it ourselves?”

Qin Tao nodded: "When we introduced French technology, we were tricked by others. They hid a lot of technology."

"You mean, the French PA series medium-speed high-horsepower diesel engines we introduced in 1978 still have room for technological improvement?" Wu Shengli thought of this and became inexplicably excited: "Then let's take the time to go to the old district diesel engine factory to do some research. , see if we can make it.”

In 1978, China National Technology Import and Export Corporation signed an agreement with the French Thermal Engine Association to introduce the PA series of medium-speed and high-horsepower diesel engine patents, which were handed over by the Sixth Engine Department to the old district diesel engine factory for trial production and manufacturing.

 Supposedly it was early enough at that time, but it was not until after the new millennium that it was widely used on the 054 frigate. What have you been doing all these years?

 Of course it’s because the French have a hand in hand.

In that year, the country spent a huge amount of money to sign a special "S.E.M.T-PIELSTICK PC2 and PA6 Diesel Engine License Authorization Agreement". In this, the French introduced the specific technical data of this diesel engine in detail: the cylinder diameter is 280 mm, and the unit diameter is 280 mm. The cylinder output power is 400 horsepower, and there are two types according to the cylinder layout, in-line L type and V type. The former has 6, 8, and 9-cylinder models with a power of 2,400-3,600 horsepower, while the latter has a 12, 16, and 18-cylinder model with a power of 4,800-7,200 horsepower.

After introducing the technology, the old district diesel engine factory immediately started trial production, starting with the simplest 6PA6L model, and soon produced an engine with a power of 2,400 horsepower. However, it was still too small for marine use, so it was mainly used on internal combustion locomotives. Later, we continued our efforts and produced 12PA6V.

  The first batch of 12PA6V was installed on the Type 918 minelayer. After its performance was verified, it was used on other missile boats.

 Just like that, it’s the 1990s.

 No one knows that the French have concealed the most important STC technology.

In later generations, veteran drivers despise turbocharging every day, squeezing power, and talk about self-priming that they have never let go of for thousands of years. In fact, turbocharged engines have a very old history, and they are also used in marine diesel engines. Turbocharger, but not enough.

 To obtain better results from the PA6 diesel engine, STC (Sequential Turbo Charging) sequential boosting technology must be used.

This sounds a bit confusing to say, but in fact, two different superchargers are connected in parallel to form a more reliable supercharging system, which is somewhat similar to that used in later generations of high-end performance cars.

 The reason is also very simple. The turbocharger is driven by the exhaust gas discharged from the engine. The higher the engine speed, the higher the efficiency of the turbocharger. However, it is impossible to fully meet the needs of various working conditions with just one turbocharger.

Taking a car as an example, using a large turbine can make the power data look better, but the burst of torque will be later. A small turbine can blow up earlier, but it will be weak later.

 If two different turbines are matched, the needs can be met. This is the twin turbine used in some high-end performance cars.

 Marine diesel engines also require this technology.

The exact same engine, as long as this technology is used, can not only improve the performance of the engine under low operating conditions, but also can continue to increase the power of a single diesel engine when the two superchargers work together at full power. Ten percent!

Because the French didn't provide it, the country had to do it on its own. It took more than ten years to design the relevant STC supercharger, and then verified it on one of its own 12PA6V-280; and then developed the 16PA6V -280STC diesel engine. Finally, the domestic diesel engine has achieved a power output of 7,000 horsepower, and can reach more than 7,700 horsepower during short-term overload operation, becoming the driving force for the new generation of domestic frigates.

However, it is still incomparable with France. France’s own frigates use the 12PA6V-280STC engine, which only requires 12 cylinders. This engine also came to the treasure island with the Lafayette-class frigate.

 Now, since Wu Shengli is interested in these, Qin Tao talked about all these technologies.

 Wu Shengli was even more eager to try.

"I heard that the localization rate of our domestic PA6 diesel engines has only reached more than 70%. These are not enough. Relevant units must continue to increase the localization rate." Qin Tao said: "We can't be too anxious about this, anyway. It will take time to finalize the Hongqi-16. As for the turbocharger used in this STC technology, we can also find a way to get it from abroad and then copy it ourselves."

 Get it abroad and copy it yourself? Wu Shengli's eyes became bright again.

 Qin Tao has it ready at hand! The Belgians want to order two bulk carriers. If he remembers correctly, the engines on them are of this type. After the engines arrive, they will find an opportunity to take them apart and look at them, and then copy them.

“Brother Tao, although we don’t have the opportunity to merge with the diesel engine factory yet, we can already find opportunities to provide supporting facilities for the diesel engine factory.” Zhao Ling said.

  Qin Tao was spitting out stars and talking all afternoon, but he still had not finalized the matter of a suitable diesel engine factory. Now, the diesel engine factory should be put aside for now, and at least it can provide supporting equipment for the diesel engine factory.

The parts Qin Tao mentioned must be produced in his own factory. The propeller factory in Huating can find time to use CNC machine tools to make a few turbochargers. It will be no problem.

“Yeah, this is a step into the threshold of making diesel engines.” Qin Tao said with a smile. Qin Tao was very satisfied with Zhao Ling’s decision to teach us.

 The design of the new frigate was discussed in the middle of the night. Qin Tao and Zhao Ling went back to sleep and then embarked on the return journey. On the night of the third grade of junior high school, Zhao Ling was finally sent to her destination and stayed in Huating's cozy home for another night. Qin Tao did not return to Mingzhou Shipyard until the fourth grade of junior high school.

As for the engine builder at Bincheng Diesel Engine Factory, it won’t be too late to meet him in a few days.

As the car approached the shipyard, Qin Tao saw two people standing like door gods at the gate. When he got closer, he realized that they were actually the two foreigners!

"Mr. Qin, you are finally back!" Carrasco was relieved: "You have been away for the past two days, which made us anxious."

"Yes, Mr. Qin, we also want to confirm the details with you. If there are no problems, we can sign the agreement." Kami said.

What? You've only been left out for two or three days, and you've already made up your mind? Qin Tao was a little surprised. How could they make a decision so quickly?

“In terms of delivery time, we hope that the ship can be delivered to us within one year after signing the contract.”

 Is the ship delivery issue so tight?

Qin Tao rolled his eyes, and then asked: "Another ship accident? Didn't you see any reports?"

"It didn't sink, but the inspection found that there were cracks..." Before Carrasco could finish his words, he was stopped by Cammy's eyes. How could you say that? Doesn't this reveal the company's secrets?

However, the words have been said and cannot be taken back.

Qin Tao smiled: "Don't worry, our group is honest and trustworthy, and we will never deliberately make things difficult for customers when they are in crisis. If we agree on 60 million ships, that means 60 million ships. We will definitely We will not take this opportunity to raise prices.”

 Kami breathed a sigh of relief.

Their company's original ships were sufficient, but after two ships sank in succession, the transportation capacity was tight. Now another one has discovered cracks and cannot continue transportation for safety reasons. This makes them nervous.

Those retail investors do not need to transport, but the goods of our long-term partners cannot be delayed!

For example, when they transport iron ore from Australia to Europe, they cannot delay. If there is a delay, the customer's steel mill will have to stop working. They cannot afford to compensate for this loss. If other transportation companies take over, then they will lose money in the future. You may lose big customers.

They must quickly build new ships. Shipyards in various countries are unwilling to accept them, so they can only pin all their hopes on Mingzhou.

At this time, Qin Tao did not take advantage of the situation and raise the price for them, so Kami finally let out a long breath, but then, Qin Tao spoke again.

"However, the construction period you requested is too tight. It is impossible for us to build a ship for you now. You have also seen it in the shipyard in the past few days. All our shipbuilding workstations are full." Qin Tao Said: "The 150,000-ton bulk carrier you require can only be built by our 400,000-ton shipyard, but now, this shipyard has not been built yet! So..."

 So what?

　　Kami already had an ominous premonition in her heart.

"We estimate that it will take at least half a year to build the dock, and then we will build the cargo ship for you. Therefore, the delivery time will be at least one and a half years."

"No, no, we can't wait so long, we hope to get a brand new and strong bulk carrier as soon as possible!" Kami is very anxious. During this year, they have to demolish the east wall to make up for the west wall, and even rent other shipping companies cargo ships, and after one year, if they still can’t get a brand new bulk carrier, then their company will probably collapse.

 One year is already the longest time.

"But, we have no choice." Qin Tao said: "Without the dock, we can't build the ship. If we sign a contract with you, we won't be able to build it by then, and you will seek high compensation, so we You absolutely can’t do this.”

Qin Tao's words are also reasonable. It's hard for a clever woman to make a meal without rice. Now Qin Tao sympathizes with them and signed the contract. When they can't build it, the other party will beat them and demand huge compensation!

"As long as you can build the ship for us within one year, it will be fine. When we sign the contract, the date clause can be removed. We don't want compensation!" Kami said quickly.

“I’m sorry, there’s nothing we can do.” Qin Tao continued to be polite.

“Well, we are willing to sponsor your dock construction!” Seeing Qin Tao about to leave, Kami became anxious and shouted immediately.

 “Sponsor our dockyard?”

"That's right, there must be a dock before we can build the ship. We are in a hurry, so we are willing to provide a sum of funds. You can use this fund to hire more workers and speed up the process. It is best to build the ship within a month. Build this shipyard! Please also take note of our sponsorship of the shipyard, seize the time, and build the ship for us within a year. Of course, even if it is overdue, we will not ask for compensation. "

"If you are willing to offer 20 million US dollars, then we can consider it." Qin Tao said.

What? Twenty million? Do you want so much?

Kami wanted to bargain, but swallowed his words. After all, this was their last chance. It was worth spending 20 million US dollars to buy time. Once the new ship was built and put into operation, it would soon be You will make your money back.

“Mr. Qin, we are willing to pay 20 million, and please arrange to build a ship for us as soon as possible!”

"Okay, I will focus on taking care of you. At the same time, we will also think of ways. Maybe we can find ways to do some preparations before the dock is built."

“Well, that would be great. But please ensure the quality. We don’t want accidents to happen.”

"Don't worry, there will definitely be no problems when building civilian ships with 400 MPa steel." Qin Tao said: "You will also send corresponding quality supervisors. You can randomly check the steel plates we use at any time. If they fail to meet this requirement, Such intensity, we are willing to compensate accordingly!”

  Qin Tao promised to use high-strength steel to build the ship, which also reassured Kami. Although it was a bit expensive, it was strong!

 There is nothing we can do about paying an extra 20 million.

“When these two ships are built, their value will be proven during navigation, and we will further design better ships, such as 200,000-ton bulk carriers, with better operating economics. There will be many opportunities for us to cooperate in the future.”

 The contract was signed that afternoon. Cong Ju was extremely surprised when she saw the terms of the contract.

These people are spending high prices to build ships here, especially 20 million to help them repair the shipyard. This money is enough for the entire investment in the shipyard. In other words, the shipyard built by us cost no money at all!
