Chapter 636 Zhenhua No. 3 ranks first in the world!
The onlookers’ ships and the helicopters in the sky all focused their attention on the Zhenhua 3.
The world’s largest crane ship is so domineering!
From the outside, it doesn’t look like a normal ship. For example, its bow is flat!
For an ordinary ship, the ship must be extended forward to form a smooth shape. What's in front of you? The bow of the ship seemed to have been cut off with a knife, and it was directly a vertical plane!
This is of course specially designed to accommodate the slewing crane with a maximum lifting capacity of 12,000 tons. The color of the crane is red, which is somewhat close to the orange hull, so that people can see it from a distance.
(Looking at the model picture, it seems that there is nothing under the bow of the ship, and there are propellers and rudders at the opposite rear.)
Since it is now in the transport state, the crane's boom does not unfold, but rotates to the hull behind. The red-and-white painted boom extends all the way to the front of the bridge at the stern.
If you only look at the proportions, you cannot see the size, and you have to add specific numbers. This Zhenhua 3 is modified from a giant cruise ship. Its total length is 320 meters. If calculated this way, its The boom is nearly two hundred meters long!
It is absolutely impossible to have a crane of this level on land, it can only appear at sea.
This arrangement is of course for balance. When lifting, the hull must remain stable and the boom must not be allowed to tip over. At the same time, in order to meet the positioning requirements during the lifting process, they also installed 2 2750 kW side thrusters, 6 3800 kW retractable azimuth thrusters and 4 3250 kW pod thrusters.
The boom is fixed on a bracket dozens of meters high, affecting the view of the rear bridge. On the white bridge, Captain Bai Hua is directing his men to sail. Guan Lao, the helmsman of Zhenhua Heavy Industry, is also standing there, smiling. Hehehe looked at the sea in the distance.
"Guan Lao, we can just carry out this task. You don't need to come forward." Bai Hua looked at the white-haired Guan Lao with some emotion. Can he withstand the wind and waves at this age?
Fortunately, our ship is fully loaded with hundreds of thousands of tons, so as long as there are not particularly strong winds and waves, the voyage will be very smooth.
"This is our maiden voyage after the completion of Zhenhua 3, and it is our first mission. Mr. Qin gave us a big order of 40 million US dollars. We have to thank him properly. Since Mr. Qin was at the scene of the accident this time, Of course I have to go there," Mr. Guan said.
The rescue fee of 100 million US dollars was split in half, and Damao should have taken advantage. After all, the cutting work was also completed by the Mingzhou Group. However, Qin Tao didn't care so much, and it was enough to get 50 million US dollars.
10 million was left as the cost of the Jiaolong. Qin Tao gave the remaining 40 million to Zhenhua Heavy Industries.
What a touching feeling in Guan Lao’s heart! When ZPMC was still very weak and could not even open the market, Mr. Qin gave them the opportunity to help them sell cranes. After that, their cranes began to occupy the global market.
Now, the Zhenhua No. 3 crane ship has just been built, and Mr. Qin has given them business again. Mr. Guan must come here, meet Mr. Qin, and participate in salvage with Mr. Qin!
Bai Hua didn't say anything. He looked at the sea in the distance. At this moment, a voice came from the radio: "No. 908 calls Zhenhua No. 3. No. 908 calls Zhenhua No. 3. Please be ready to pick up the plane. We will Take off a helicopter and land on your helipad."
The bridge area behind the Zhenhua 3 is very large and can accommodate many people. In fact, it was originally part of the cruise ship. It was not dismantled and was used directly. There is a good-sized apron on the top of the rear, which can Allow large helicopters to dock. In fact, looking at the area, vertical take-off and landing fighter jets are almost the same.
"Welcome! We welcome you warmly!" Mr. Guan said excitedly: "Now, organize people to welcome you on the tarmac immediately!"
After saying that, Mr. Guan ran out first.
A Z-8 flew over. Compared to this huge apron, it seemed too small. After the helicopter landed smoothly, Qin Tao was the first to come out.
"Guan Lao, are you too enthusiastic? There are so many people?"
Qin Tao looked at the two rows of people standing outside. There were twenty or thirty people in total. These people were holding flowers in their hands. It seemed that the conditions on the boat were good and they could even grow flowers!
“Mr. Qin, no matter how grand this reception ceremony is, it cannot be too grand!” Mr. Guan said, “Our Zhenhua Group has benefited a lot from you.”
"This is all as it should be, Mr. Guan, you're welcome." After Qin Tao finished speaking, he looked at Nicholas walking behind him and said: "Let me introduce to you, this is the person in charge of this salvage work. Nicholas."
“Welcome, welcome, would you like to dine in our cabin?”
"No, let's take a look at the ship first." Popov said as he came down.
In the air, Popov was already drooling when he saw the ship. Now, standing on the helipad and looking at the huge boom in front of him, he was drooling even more with envy. It was 12,000 tons. It is the only one in the world with lifting capacity!
“Okay, let me show you around. Let’s go forward and go to the front of the bridge so that we can see our crane from the best perspective.” Mr. Guan was also excited.
“Excuse me, how can you develop such a large crane ship?” Popov asked as he followed.
After hearing the translation, Mr. Guan smiled and said: "This is also necessary for our domestic construction and development. First of all, the first one is the hoisting and disassembly of offshore platforms, especially offshore drilling platforms and offshore wind farms. Generators all require large-scale crane ships. Secondly, large-scale bridge projects and bridge deck hoisting of various bridges also require large-scale crane ships. After having large-scale crane ships, we developed the concept of quickly salvaging sunken ships. "
In the past, if there was no relevant equipment, special methods such as hanging pontoons had to be used to salvage. Now, with large-scale crane ships, the sunken ship can be lifted directly, making salvage operations more convenient.
“How do you achieve this lifting capacity?” Popov asked.
They plan to install 26 cranes on the barge for the first half of the salvage. Now, the behemoth in front of them can be handled with just one crane. This is not an order of magnitude at all!
How does a crane lift more than 10,000 tons?
"Actually, it is equivalent to a combination of two six-thousand-ton cranes. As you can see here, it has two sets of parallel booms. Each set of booms can lift six thousand tons. When the two sets are combined together, it is ten thousand tons. It has a lifting capacity of two thousand tons. Of course, we have made some reservations. In fact, if it is used to the limit, it will be no problem to lift fourteen thousand tons."
Many manufacturers like to brag. They can only lift 800 tons, but they will brag that it is 1,000 tons. This shows that their company's technical strength is strong. However, Zhenhua Group likes to keep a low profile and mark its lifting data smaller.
This is just like building a car. Some car companies like to mark their engine data very high, often 200 horsepower, or even more than 200, making them the best in the world. However, when the horsepower meter is used, the secret is suddenly exposed. , the power of two hundred horsepower is less than one hundred and fifty when it is put on the wheels. Some luxury cars don't need to rely on horsepower to show off. They all like to have low bids, with a bid of 180 horsepower. The tested wheel power is only high but not low.
“Even if there are two cranes, each of them weighs 6,000 tons, which is already incredible. For example, how can the steel cables on it withstand such a heavy gravity?”
“Our supplier can provide us with whatever size we need, and the blocking cables for our aircraft carriers are also provided by this supplier.”
It actually uses the aircraft carrier's arresting cable technology?
It’s no wonder, aircraft carrier arresting cable technology is the Mount Everest of steel cables! Popov was very emotional.
In fact, the technology of the aircraft carrier's arresting cable is not as strong as the steel cable technology required by this kind of crane. The arresting cable provided by Juli Company is actually just a simplified version of the steel cable technology, and it is not the best at all.
“Our ship Kuznetsov also lacks blocking wires now.” Nicholas said: “Qin, if I go to Moscow in the future, I will definitely purchase blocking wires from you.”
The Kuznetsov aircraft carrier is assigned to the Northern Fleet, so Nikolai has not yet gotten involved. Even if he knows that the aircraft carrier lacks blocking wires and that the blocking wire manufacturer during the Red Empire period has closed down, he cannot give it. Coordination will only be possible in the future, when he becomes a higher leader.
"Of course, we will sell it to you at the best price." Qin Tao nodded: "If a third party wants it, it can also sell it through you and let you make some money."
A smile appeared on Nikolai's face. Of course he knew that Qin Tao was talking about Asan. Asan's navy is currently ambitiously developing their aircraft carrier business. They use ski jump takeoff and blocked landing plans. Of course Aircraft carriers are also needed.
It is impossible for Ah San to purchase directly from the East, but he can resell it through Damao, and everyone can make money. You must know that the blocking cable is a consumable and must be replaced every 100 takeoffs and landings blocked. The supply of this thing is long-term. of.
"How do they have such a ship? In the East, our shipbuilding ability is the strongest!" On a watching ship, a man with a mustache under his nose replied.
"Yamamoto-kun, Dongfang people have made rapid progress in the past few years. They have monopolized half of the world's natural gas ship orders. Their dredgers are even more unique. The crane ships in front of them are also the best in the world. Our San0 Heavy industry must face this point. Your Changqi Shipyard is our most important shipyard. You must work hard to develop and not let Mingzhou Group become the strongest shipbuilding group here!" The person in charge of Sanli Heavy Industry added Mountain Beast said.
Originally, 30 Heavy Industry was the strongest natural gas carrier manufacturer in East Asia. However, they mainly manufactured Moss tank natural gas carriers. The weight of this type of ship was incomparable to that of Yinwa Steel's membrane natural gas carriers. Therefore, , now their orders are getting less and less.
As for dredgers, Mingzhou Group is even more powerful. It has built the most advanced dredgers in the world. If you look at the islands that appear in the southern seas, you will know how incredible this kind of dredger is.
The crane ship is right in front of you.
How can we compare from now on?
“From a technical perspective, I’m afraid we can’t compare with them.” Inutaro Yamamoto said.
"so what?"
“So, we have to think of other ways, for example, we destroy a natural gas ship they made and then publicize internationally that their ships are unreliable.” Yamamoto Inutaro said.
Broken? Unreliable?
Masuyama Beast nodded: "Yes, Yamamoto-kun, this is a good idea. The natural gas ship of Sanhang Heavy Industries leaked, causing Sanhang Heavy Industries to completely disappear. Now, we will use the same method to make Mingzhou The group has completely disappeared!”
If you can't compete with your competitors, then think of various ways to make them infamous!
The fleet has gathered, the salvage plan is under discussion, and everyone is full of expectations.
"The two hooks of the crane can just hook one side of the rear half of the submarine." Taking the plan sent by Huating, Qin Tao introduced to everyone: "At the tail of the submarine, we put the two propellers and the fixed shaft of the rudder Bundle them together so that they can withstand the tensile force of the steel cables. We will drill twenty holes on the cut keel and fix the twenty steel cables. After connecting them together, they can withstand enough tensile force. .”
If you have seen a tower crane lifting heavy objects, you should know that when the tower crane is lifting, two hooks are hung on one side, and then the heavy objects can be lifted away. Especially when lifting the previous prefabricated floor slabs, they are hung directly on the The round hole in the center of the floor seems to be able to be decoupled at any time, but it is actually very safe.
The current lifting plan is similar to the hanging floor slab, which needs to be hung on both sides.
Popov could only be surprised.
This is a submarine with a displacement of 24,000 tons. The torpedo room at the bow has been cut off and divided into two parts from the back. Therefore, the tail is probably about 10,000 tons. However, even so, it must be viewed from the front and back. It is somewhat contrary to common sense to lift the rear half of the submarine from both ends.
Generally speaking, lifting holes should be drilled from both sides. In this way, the distance between the steel cables on both sides is only ten meters. What now? It was actually lifted front and back, and the distance between the two hooks was a full sixty or seventy meters!
Can this be hoisted?
What if during the lifting process, the center cannot bear the tensile force and breaks directly?
Danger, this is really too dangerous!
“The biggest advantage of our lifting method is that it avoids the influence of various external factors. The lifting will be the smoothest.” Qin Tao said: “After rigorous calculations, this lifting method will not cause any problems.”
If it is lifted from left to right, will the force on the front and rear of this long object be uneven during the lifting process, causing it to become vertical instead of horizontal? This can cause serious problems. Now, if you lift it front and back, it will be fine. The water will definitely come out smoothly.
Nicholas nodded: "Since you have already calculated it, let's do it this way!"
“Then tonight, the Jiaolong will complete the drilling work and make preparations for lifting.”
There is more than one group of operators on the Jiaolong. During this period, everyone has become accustomed to taking turns to work. The Jiaolong did not have any problems during such high-intensity operations, which fully demonstrated the construction quality of the Jiaolong. Reliable and top-notch performance.
When the sky in the east began to turn fish-belly white, the onlookers saw the Zhenhua 3 begin to rotate its boom, which meant that it was about to be lifted!
"The lifting quality of this kind of crane is enough, but it is not easy to lift a big thing of more than 10,000 tons from the water. The underwater undercurrent will cause various effects on it. The whole lifting process may It will last for a few days, and it may even fail." Yamamoto Inutaro began to comment again: "If the salvage fails and the second half of the submarine falls..."
"Then our entire sea area will face pollution." Masuyama Xiongju said: "Although we hope to see Mingzhou Group make a fool of ourselves, we don't want to see such an accident happen. In this way, our fishery will be greatly affected. A big hit, we will have a hard time selling our seafood, you know?"
Inutaro Yamamoto nodded: "Yes, **** it, why do they want to organize exercises in this sea area?"
"If we are not in this sea area, why should we go to the Pacific Ocean?" Zengshan Male Beast's eyes were gloomy: "That would be even worse news!"
"Don't worry, we have a fleet of eighty-eight, which is being expanded to a fleet of ninety. What do the Easterners have? Their most advanced warships are still second-hand goods purchased from Da Mao. They have nothing to fear at all."
"No, no, they have already started building a battleship similar to Aegis..." Before Zengshan Xiongju finished speaking, his eyes looked into the distance: "The hook has already started to go down!"
The huge runner is rotating, and the steel cables are constantly extending. The brackets at the front and rear of the crane are like wire towers for high-voltage lines, and the densely packed steel cables extend to the hook in front.
Plop!
The hook entered the water.
You can’t see the hook anymore, you can only see that the steel cable is still extending, extending...
This process is long. Even if the hook falls at a speed of one meter per second, it will take more than a thousand seconds. In addition, it will slow down after reaching the target depth. It will take more than half an hour in total to lower the hook. .
The sea water is gently lapping at the Zhenhua 3. The 150,000-ton ship is steady and motionless.
“They must have an advanced dynamic positioning system underwater, and it is fully automatic!” Watching the crane ship operating from a distance, Inutaro Yamamoto began to analyze it again.
No matter how heavy the hull is, it will float with the flow of the ocean, but now, this crane ship is motionless, which shows that it is constantly adjusting its state, and it is adjusting dynamically.
The requirements for this technology are very high. I never thought that Orientals could actually develop this technology!
When lifting at sea, if the crane ship rocks back and forth, it will be very detrimental to the lifting operation. It has to be stationary just like on land. The crane ship in front of you has already done this.
Others also saw it, especially the insiders, and they all began to think: Maybe we can ask this crane ship to help us with some of our operations in the future!
As everyone watched, the crane stopped moving and the steel cable was finally lowered!
Then, there is another long wait, and it also takes a long time to hook up.
There was a new sizzling sound from the hydraulic motor on the crane, and the steel cables began to lift up and down. Finally, all the steel cables were tightened.
It’s been lifted, it’s about to be officially lifted!
In the sky, on a hovering helicopter, the camera lens was pointed at this place and kept recording. This was the first time in the world that a submarine wreckage of more than 10,000 tons was directly lifted from a depth of more than 1,000 meters underwater!
If the hoisting can be successful this time, it will shock the whole world.
In the past few years, the most advanced technologies were all from the West. Dredgers, natural gas ships, semi-submersible ships, and ships for various special operations were all blank in the East. In the past few years, the development in the East has been so fast that now it is It has reached a world-class level!
The people watching had different moods.
On the crane, Nicholas was in a good mood.
“The hook has been successfully hooked and the cable is tightened, so what are you waiting for? Let’s start lifting now!” Nicholas said.
“Yes, start lifting!”
The surveillance footage from the No. 908 was also transmitted in real time. On the monitor, you could see the blurred outline of the nuclear submarine.
Start lifting!
The hydraulic motor of the crane continued to operate, the cable moved upward, and the body of the big guy underwater began to shake.
Once, twice, three times. If you can transmit the sound at this time, you will definitely hear a crunching sound!
Finally, the big guy’s figure started to shake! After shaking twice, it began to turn slightly at an angle, and its belly no longer encountered resistance.
Get up, get up!
Nicholas held his breath, his heart was pounding. Whether he could successfully lift him or not depended on this hammer.
fine!
There were no accidents in the second half of the submarine. It moved steadily upward, one meter, two meters, three meters. It left the bottom of the sea and was floating upward!
“Great, we finally have to fish it out!”
Popov stood behind the two of them, envious but also worried. They had to salvage the first half, but what if the salvage failed?
It took half an hour to release the hook, but it took a full two hours to lift the entire rear half of the submarine! The sling rises very slowly. After all, there is a big thing of 10,000 tons below. If it goes too fast, if something goes wrong, it will cause terrible consequences.
The Jiaolong has been surrounding the area, supervising the entire process of underwater lifting. With the images it sends back, it will be much safer.
“If it were an attack nuclear submarine with a weight of less than 10,000 tons, wouldn’t it be able to be salvaged at once?” Someone lamented.
"Of course."
“Attention, it’s coming out, it’s coming out!”
The tail of the huge nuclear submarine is exposed out of the water. It looks so spectacular. The largest underwater whale is only more than thirty meters long. The length of the section currently salvaged underwater is sixty or seventy meters long!
Everyone is excited. What does the second half of the Oscar-class nuclear submarine look like? In particular, what does the propeller on its tail look like? The mystery is about to be revealed!
