Chapter 243 Diesel-Diesel joint promotion plan
Cong Ju looked at Qin Tao with eyes full of admiration. Mr. Qin was asked to sign the contract. He was so awesome!
Originally, she thought that it would be good to get the other party to accept the price of a cargo ship of 60 million US dollars. Unexpectedly, she did not expect that the other party would voluntarily undertake the construction of the shipyard. This was simply unbelievable.
However, the contract is in front of you, and all these are facts.
“Everyone, our shipowners are very much looking forward to shortening the construction period as soon as possible, so now we need to brainstorm ways to speed up the construction of these two cargo ships.”
At this time, Qin Tao called everyone for a meeting, and of course the Belgians were also present. Qin Tao kept his word. Since he wanted to help the other party complete the construction of the ship as soon as possible, of course he had to gather everyone together to find a solution.
“Yes, the shorter the construction period, the better.” Kami said, looking at the people present with eager eyes.
So, Cong Ju coughed, and then said: "Mr. Qin, if we want to speed up the construction period, I have a way. For example, while we are building the shipyard, we can build a one-thousand-ton container directly next to the shipyard. After the shipyard is built, these sections can be directly lifted and welded, which can greatly shorten the construction period."
This plan was originally thought up by Qin Tao, but now, it is not appropriate for Qin Tao to say it. Cong Ju is considerate and takes over.
Kami's eyes lit up: "Yes, this is a good idea! Mr. Qin, you have a lot of talents here!"
Cong Ju lowered her head modestly.
"There is a way, but we still lack enough workers. After all, we are currently carrying out many projects at the same time." Qin Tao said: "We can first transfer some people from other projects, and then we need to continue to recruit workers. Recruiting excellent technical workers.”
Mingzhou Shipyard is expanding too fast! Their excellent workers are always in short supply, so they have to continue to recruit them.
After Qin Tao finished speaking, he looked at his father who was napping beside him: "Director Qin, I leave this matter to you."
"Um?"
“We still need at least hundreds of outstanding workers, and we’ll leave them to you.”
?
Qin Baoshan's eyes were filled with helplessness.
“Continue to poach people from other shipyards. No matter what the conditions are, we must poach their outstanding workers. This is the order of the group.”
Now Qin Tao likes this feeling very much. His father is usually very arrogant and calls Qin Tao a little brat, but now, Qin Tao is his superior and gives orders to him. , Dad must abide by it.
“This construction task is very important, so Cong Gong, you should be in charge. For the natural gas ship, you can designate a deputy.” Qin Tao said.
Cong Ju is definitely the one who plays the leading role in the shipyard. Qin Tao feels most at ease with Cong Ju, so of course, this arduous task is given to Cong Ju first.
Cong Ju nodded: "The deputy leader of our welding team can take on the task."
Cong Ju also knows that what Qin Tao lacks the most is talents who can take on important roles, so she has been deliberately cultivating them. Now there are already people who can take up the important tasks, as long as she takes care of them.
“Mr. Qin, thank you for your support.” Kami said gratefully.
With Qin Tao's arrangement, even if it may not be completed according to the construction deadline, at least it can be regarded as his best effort. For Kami who was desperate, this was already the greatest kindness.
"Please rest assured that we will try our best to build it according to the date you need." Qin Tao said: "Next, we also have a plan for a 200,000-ton bulk carrier. If you need it, you can place it at any time. Order."
Since it can’t pass through the Suez Canal anyway, the bigger the ship, the better.
Although Qin Tao proposed this type of ship when negotiating the conditions, Kami was not interested. It is only now that everything has been arranged, and Kami is finally in the mood to consider other things.
At this time, Kami’s eyes widened when he heard Qin Tao talking about a 200,000-ton bulk carrier: “200,000 tons?”
“Yes, it can transport 180,000 to 90,000 tons at a time, and the economic benefits of this kind of bulk carrier will be even higher.”
Kami swallowed his saliva: "Would this kind of bulk carrier be more expensive if you were entrusted to design it?"
"It's not expensive, it's not expensive, it's still 100 million US dollars." Qin Tao said: "If you build ten of them, the design cost will only be 10 million on average, which is definitely worth the money."
That’s quite painful! Kami thought secretly in his mind, and he quickly changed the topic: "With the larger tonnage of this kind of bulk carrier, will it face more serious risks such as breakage?"
“Of course not, we will use steel plates with higher strength, such as 500 MPa, to absolutely guarantee safety,” Qin Tao said.
Only they are willing to use high-strength steel plates so extravagantly to build it.
At this time, Carrasco couldn't help but ask: "Excuse me, which steel plant do you plan to use for the steel plates?"
The contract has been signed and the strength of the marine steel plates has been determined. However, they do not yet know where the Mingzhou Shipyard plans to use the steel plates produced.
"Of course it belongs to our Mingzhou Steel Plant. If you have time, I can take you to see it tomorrow." Qin Tao said: "Our Mingzhou Steel Plant has first-class production equipment and can produce various high-performance products." As you have seen, we are manufacturing aircraft carriers and destroyers on our slipway. These warships also use steel produced by our Mingzhou Steel Plant."
Kami and the others came here and had already learned about it in advance. They knew about several famous steel-making companies here. However, they absolutely did not know that there was actually a steel plant here in Mingzhou!
“I heard that the best steel in China comes from Anshan Iron and Steel, Baosteel, and Mingzhou Iron and Steel Works?”
If they were not afraid of causing misunderstanding, they would probably have explained what the state steel plant is? Never heard of it!
Qin Tao smiled: "The development of our motherland is changing with each passing day. What you know is already old history. The production equipment of our Mingzhou Iron and Steel Plant is also imported from the island country, and it has the same high-quality products as Anshan Iron and Steel Baosteel. Tomorrow you go You'll know after seeing it. Director Qin, please take these guests to our steel factory tomorrow."
Anyway, Dad is like a hard-working old scalper. There is no problem in arranging him to do these things.
“Yeah.” Sure enough, Qin Baoshan nodded.
Qin Tao has finished fooling the Belgians. The contract has been signed anyway, and the down payment will arrive tomorrow morning. The other party can only rely on himself, and there are no other variables.
Chin Tao has more important things.
For example, having a meeting.
Yang Dawei and everyone in the design department sat in the conference room and looked at Qin Tao with bright eyes.
“Mr. Qin, just give us the order. A two hundred thousand ton bulk carrier is a piece of cake for us.” Hu Jia said excitedly, his eyes full of little stars.
“A 200,000-ton bulk carrier? When did I say that?” Qin Tao looked at these people in surprise.
"Mr. Qin, didn't you tell the Belgians that you had prepared a design for a 200,000-ton bulk carrier for them?" Yang Zhaoxiang said: "Although this kind of bulk carrier is not what we are most looking forward to, but, After all, it’s a $100 million job!”
Qin Tao then realized that he had deceived the Belgians, but he had also deceived these people into being fascinated?
“We’ll talk about this kind of ship later. The task I give you now is to design a frigate with a displacement of four thousand tons.” Qin Tao said, “Is this what you like?”
Everyone opened their eyes wide.
“Mr. Qin, a frigate of four thousand tons?” Zhang Chao said in surprise: “How is this possible?”
"Look at you guys, have you never seen the market? I have already reported this project to the Navy leaders. According to their progress, it will probably take a few months or even half a year before the project will be officially approved. By then, we can We took our detailed design drawings and went to the Navy to bid, and I’m sure no one can bid against us.”
Everyone's face was filled with excitement, but Yang Dawei frowned slightly. This action was noticed by Qin Tao at a glance: "Why, Yang Gong, do you have any concerns?"
"Mr. Qin." Yang Dawei gritted his teeth and finally spoke: "Warship orders are a piece of meat. Many shipyards are watching. We already have contracts for two 051Cs, which has already made some brother units jealous. Now, If we take the frigate contract into our own hands, there will be no guarantee that there will be no rumors, which will be detrimental to you and your father-in-law."
Yang Dawei’s concerns are not unfounded.
Once someone maliciously spreads rumors, it will still bring a lot of trouble to Qin Tao and Wu Shengli.
Yang Dawei is very experienced in this industry and knows a lot of things, so now, he is giving Qin Tao a heads up.
It’s easy to dodge open spears but hard to defend against hidden arrows, spitting stars will drown people!
Qin Tao smiled: "Gong Yang, you are right. Frigates are different from destroyers. Frigates need to be built in large quantities. Therefore, it is not suitable for us to eat all the fat in our mouths. So, we are Gotta find a way."
When Qin Tao just decided to stay and lead the shipyard out of trouble, what they encountered was still a mess, so they had to compete for orders, but it is different now. Now their shipyard continues to grow and develop, and they already have a large number of orders, profits have also increased rapidly, and now they no longer need to eat alone.
Eating too much when eating alone is not necessarily a good thing.
However, it would not be in line with Qin Tao's style if he directly allowed others to take advantage of him. Therefore, when Qin Tao said that he wanted to find a way, everyone was looking at Qin Tao expectantly.
“We must go all out when bidding, but after the bidding is completed, we can subcontract part of it to other units.” Qin Tao began to talk about his ideas.
Subcontract? A white wolf with empty gloves? Sure enough, Mr. Qin will never be lenient when it comes to making money, and while making money, he also appeases his fraternal units!
"For example, the Navy wants to start construction of four frigates at once. After we win the bid, we can only start construction of two ships. The remaining two ships will be built by our brother units, whether it is Huating Shipyard or Bincheng Shipbuilding. It can be done by any factory. However, we are still the general contractor, and this cannot be changed."
It doesn’t matter whether he is a general contractor or a sub-contractor, as long as he can get orders and make money.
“In this case, China Shipbuilding Industry Corporation will probably call you Zhou Bapi.” Yang Dawei said.
Qin Tao smiled: "Just scold me. If you have the ability, they will bid for it! In addition to subcontracting to them, we can also provide them with other benefits, such as introducing foreign customers to them and allowing them to create foreign trade projects." ship, or transformed into a coast guard ship, etc.”
This is just a temporary idea of Qin Tao. If you eat meat yourself, you have to give soup to others. Whether this method is feasible will be discussed later. Next, let’s talk about the design ideas of this frigate.
After Qin Tao explained the overall design, everyone became excited again, and they had completely shifted their attention to the technical aspects.
“Mr. Qin, are you sure to use four diesel engines for this power?” Yang Dawei asked Qin Tao.
Qin Tao nodded: "If we don't use a diesel engine, why should we use a gas turbine? We don't have that thing either!"
Frigates are equipped with a large amount of equipment and must be economical. Even if gas turbines can be produced domestically in the future, they will be reluctant to use them on frigates.
“Yes, when we were demonstrating the 053 frigate project, we had requested the use of a diesel-fuel combination. However, because the gas turbine was not qualified, we could only develop a two-engine, dual-shaft propulsion solution.” Yang Dawei was deeply touched.
Yang Dawei has previous work experience and participated in the development of many projects, including the 053 frigate. In the context of that era, the military put forward very high indicators, for example, the speed must reach 33 knots, and the power system uses a 390 diesel engine. and 401-II gas turbine combined power plant.
This was not enough. Later, we continued to demand an increase in speed, preferably reaching 38 knots. This was simply forcing the ship to do something difficult. In the end, they decided to use two 18E390VA medium-speed diesel engines as the cruise unit and one 851 gas turbine with a rated power of 16,170 kW as the acceleration unit, with a total power of 46,000 horsepower and 3-axis propulsion.
Although the speed index can be achieved in this way, the 851 gas turbine developed at that time has a lifespan of only 200 hours and cannot be installed on ships at all.
The pace was too big, and it was easy to tear the eggs. Therefore, they finally decided to use two 18E390VA medium-speed diesel engines as the main engine, with a power of 12,000 horsepower and a 053 frigate of more than 1,000 tons, and that’s how the 053 frigate came out.
Later, this frigate was continuously modified. Up to now, it has developed into the 053H2G frigate. Because it has changed too much compared to the previous one, it is also called the Jiangwei-class frigate by NATO. Currently, the first warship is about to complete its final sea trials. It will be delivered to the Navy soon.
For the navy, this 053H2G frigate is competent. It is the first domestic closed frigate with air defense, anti-ship, and helicopter anti-submarine capabilities. It is a good step for domestic new steps to run quickly and slowly catch up with the advanced level of the West.
“No, that’s not what I’m talking about.” Yang Dawei suddenly realized that he had just been taken away by Qin Tao and almost forgot the question he wanted to ask.
“I mean, we use four diesel engines to drive two propellers, so this will involve the problem of parallel vehicles. We have never done this before, and we don’t have any technical reserves!”
Yang Dawei is worried about this!
For a frigate with a displacement of 4,000 tons, it is impossible to use two diesel engines. It must have four. However, it cannot drive four propellers, so it is necessary to make a plan of two diesel engines driving one propeller.
In specific technical terms, this is called CODAD.
Two diesel engines of the same model drive a propeller through a transmission mechanism. This is tricky.
When cruising at ordinary times, only one diesel engine is used, which is more fuel-efficient. After all, cruising does not need to be very fast. When it is time to accelerate or sprint at full speed, the second diesel engine can be added to work together. In this way, the two diesel engines can work together. The two diesel engines must be closely coordinated, and the output power must be exactly the same!
This has never been done before in the world. This is an innovation!
Other power systems also have this problem. For example, the world-popular diesel power solution uses a diesel engine at low speeds and a gas turbine at high speeds. At this time, it is inconvenient to run a gas turbine and a diesel engine together, so most of them use diesel engines. The alternating combustion scheme (CODOG) uses either a diesel engine or a gas turbine alternately, which combines the advantages of the gas turbine's high power, fast starting acceleration and fuel-saving diesel engine.
Technicians from only a few countries have been able to solve the problem of combining diesel engines and gas turbines, and have created a specialized CODAG, which is a combined diesel power system.
(There are others, but Heroes of East China is not popular.)
There are very few warships driven by a combination of diesel and diesel. The French Lafayette class is one of them. However, the Lafayette class uses a main engine and an auxiliary mode to drag the small one, and does not use two identical engines. plan.
So, after hearing Qin Tao talk about the specific technical details, Yang Dawei began to struggle with this issue.
In the past, we had several engines and just drove a few propellers, each doing their own thing. There was no problem. Now, it is not that easy to have two engines running in parallel to drive one propeller!
"What's so difficult about this?" Qin Tao drew a sketch: "There are two engines on both sides, which drive small gears through clutches, and a large gear in the center. This becomes a reducer and drives the propeller behind to rotate. , we need to find the mathematical model of the two engines and propellers when they are working, and then conduct simulation calculations to find the best solution for merging..."
For Yang Dawei, these seemed to be difficult, but for Qin Tao, it was nothing at all, because Qin Tao in the previous life already knew these techniques.
At the same time, this also reflects the difference between Wu Shengli and Yang Dawei.
Although Wu Shengli is a naval leader, he is not familiar with the specific technical details. When Qin Tao proposed this plan, Wu Shengli was concerned about whether the engine power was sufficient. Wu Shengli didn't care about the others. However, when Yang Dawei arrived, he had to think clearly about how to operate the two engines in a coordinated manner.
It’s just that the plan proposed by Qin Tao is too lofty, right? Establish a mathematical model and then perform simulation calculations? This thing sounds very mysterious.
“I seem to understand.” Zhang Chao said: “We need to use computers to solve this problem!”
"That's right, that's it. Then this task will be left to you!" Qin Tao immediately assigned the task by name: "You don't need to do other designs, just make the simulation model of this parallel car."
Zhang Chao nodded: "I will work hard."
“Gong Yang, do you have any questions?” Qin Tao continued to ask.
Yang Dawei is an experienced technician, and his opinions can supplement some of Qin Tao's mistakes.
"Others, nothing more, but these are all based on the premise that our comrades from relevant units can successfully imitate them, such as air defense missile systems, roof radar systems, etc." Yang Dawei said: "There will be problems with these subsystems. We might go blind."
Qin Tao nodded: "These won't be a big problem."
“By the way, the processing of these components will be a big problem, especially if it has to withstand thousands of horsepower. The reliability of the clutch that disconnects and connects the power is very important, and it probably takes a lot of thinking.” Yang Dawei said.
Qin Tao smiled: "Do you think of this thing as the friction plate clutch in the car? No matter what kind of friction plate, it can't withstand this kind of power! What we want to use is a special synchronization mechanism The toothed clutch is composed of a ratchet pawl and a spiral spline. Under true torque, the clutch automatically engages, and under reverse torque, the clutch automatically disengages. This kind of clutch is completely rigid transmission and is simply impossible There are friction plates. The power transferred is high, but the size and weight are small."
As Qin Tao spoke, he briefly drew the design of this clutch. Yang Dawei looked at the exquisite idea and couldn't help but give a thumbs up.
“Mr. Qin, your design is great!”
"Well, I think so. Our design must be patented. This is our technology!"
“Mr. Qin, applying for a patent takes time. In order to avoid leaks, I think it is better for us to produce these devices ourselves.”
Qin Tao nodded: "That's right. Leave it to our propeller factory for production. There are CNC machine tools there. I have said before that if they change the name, it will be called a machinery factory. It has to be called a propeller factory. I’ll have to change my name in the future.”
After Qin Tao designed the turbocharger, he planned to hand it over to Huating's factory for production. It seems that those guys still can't clearly understand their own positioning!
