The onlookers' ships and the helicopters in the sky all focused their attention on Zhenhua No. 3.
This 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 ordinary ships, the ship has to extend 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 house 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 below the bow of the ship, but there are propellers and steering gears at the opposite rear.)
Since it was now in transport mode, the crane's boom did not unfold, but slewed to the hull behind. The red-and-white painted boom extended 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 mission. 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 no particularly strong winds and waves, the voyage will be very smooth.
"This is our first flight after the completion of Zhenhua 3. It is the first mission. Mr. Qin gave us a big order of 40 million US dollars. We have to thank him properly. Since Mr. Qin is here this time Of course I had to go to the accident scene," Mr. Guan said.
The rescue fee of 100 million US dollars was split in half. Damao's side should have taken advantage. After all, the cutting work was also completed by the Mingzhou Group. However, Qin Tao didn't care so much, it was enough to get 50 million US dollars.
Qin Tao kept 10 million as the cost of the Jiaolong, and gave the remaining 40 million to Zhenhua Heavy Industries.
Guan Lao was so touched! 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 said nothing and looked at the sea in the distance. At this moment, a voice came from the radio: "No. 908 is calling Zhenhua No. 3. No. 908 is calling Zhenhua No. 3. Please be ready to pick up the plane. We will Take off a helicopter and land on your tarmac."
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 give you a warm welcome!" Mr. Guan said excitedly: "Now, immediately organize people to welcome you on the tarmac!"
After saying that, Mr. Guan ran out first.
A helicopter 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 what should be done, 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 did 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, would have 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 capability?" Popov asked.
Their plan to salvage the first half of the salvage was to install 26 cranes on the barge. Now, the behemoth in front of them can be handled with just one crane. This is not an order of magnitude at all!
How can 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 can lift fourteen thousand tons."
Many manufacturers like to brag and boast that they can lift only 800 tons, but they will boast that it can lift 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 as 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 them withstand such a heavy gravity?"
"Our supplier can provide whatever size is needed, and the arresting cables of our aircraft carrier are also provided by this supplier."
It actually uses the aircraft carrier's arresting cable technology?
It’s no wonder that 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 for this kind of crane. The arresting cable provided by Juli Company is actually just a simplified version of the steel cable technology and is not the best at all.
"Our ship Kuznetsov also lacks blocking wires now." Nikolai said: "Qin, if I go to Moscow in the future, I will definitely purchase blocking wires from you."
The aircraft carrier Kuznetsov is assigned to the Northern Fleet, so Nikolai has not yet
If he was involved, even if he knew that the aircraft carrier lacked blocking wires and that the blocking wire manufacturer during the Red Empire had closed down, he would not be able to coordinate. Only in the future, when he becomes a higher leader, would he have this ability.
"Of course, we will sell it to you at the best price." Qin Tao nodded: "If a third party wants it, it can be resold through you and you can make a fortune."
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. We 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 Sanqi 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.
[The problem of slow update of new chapters can be solved by
However, even so, it is still a bit contrary to common sense to lift the rear half of the submarine from the front and rear 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 we will complete the drilling work on the Jiaolong tonight 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 white, the onlookers saw the Zhenhua 3 begin to rotate its boom, indicating 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 Yuju 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 blow, we will have a hard time selling our seafood, you know?"
Yamamoto Inutaro nodded: "Yes, damn, why do they organize exercises in this sea area?"
"If we are not in this sea area, why should we go to the Pacific Ocean?" Masuyama 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."
"No, no, they have already started building a battleship similar to Aegis..." Before Masuyama Malemon could finish his words, he looked into the distance: "The hook has already started to go down!"
The huge runner was rotating, and the steel cables continued to stretch out. The brackets at the front and rear of the crane were like wire towers for high-voltage lines, and the densely packed steel cables extended to the hook in front.
Plop!
The hook went into 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 was gently lapping at the Zhenhua 3. The 150,000-ton ship was steady and motionless.
"They must have an advanced dynamic positioning system underwater, and it is fully automatic!" Watching the operation of the crane ship from a distance, Yamamoto Inutaro 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 as motionless as it is on land, and the crane ship in front of it has already done that.
Others also saw it, especially the insiders. At this time, they began to think: Maybe they can ask this crane ship to help with certain 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.
A new sizzling sound came from the hydraulic motor on the crane, and the steel cables began to lift up and down. Finally, the steel cables were all 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 world.
In the past few years, the most advanced technologies were from the West. Dredgers, natural gas ships, semi-submersible ships, and various special-operation ships were all blank in the East. In the past few years, the East has developed so fast that now it is It has reached a world-class level!
The people watching had different moods.
On the crane boat, 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 No. 908 was also transmitted in real time. On the monitor, you could see the outline of the nuclear submarine in Mohu.
Start lifting!
The hydraulic motor of the crane continued to move, 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 the crunching sound!
Finally, the big guy's figure began 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 and his heart was beating rapidly. 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, feeling envious and worried at the same time. 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 is too fast, if something goes wrong, it will cause terrible consequences.
The Jiaolong has been around nearby, supervising the entire process of underwater lifting. With the pictures 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, and it looks so spectacular. The largest whale underwater 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!
