Chapter 636 Zhenhua No. 3 No. 1 in the world!

  The watching ships and the helicopters in the sky all focused on Zhenhua-3.

  The world's largest crane ship is too domineering!

  From the outside, it doesn't look like a normal ship, for example, its bow is flat!

  For ordinary ships, the capital of the ship must extend forward to form a smooth shape. What's in front of you? The bow of the ship seemed to be cut off with a single 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 people can see it from a distance.

   (Looking at the model diagram, it seems to be at the bow, there is nothing under there, and there are propellers and steering gears on the opposite rear.)

  Because it is now in the transportation state, the boom of the crane has not been deployed, but has turned to the hull behind, and the red and white painted boom has been extended to the front of the bridge at the stern.

If you only look at the proportions, you can't tell the size, and you have to add specific figures. This Zhenhua No. 3 is refitted from a giant cruise ship. Its total length is 320 meters. If calculated in this way, its The boom is nearly two hundred meters long!

  It is absolutely impossible to have a crane of this level on land, only at sea.

Of course, this arrangement is also for balance. When lifting, the hull must remain stable, and the boom must not be turned over. At the same time, in order to meet the positioning requirements during the lifting process, they also installed 2 on the hull. 2750 kW side thruster, 6 3800 kW retractable azimuth thrusters and 4 3250 kW podded thrusters.

The boom is fixed on a bracket tens of meters high, which affects the sight of the rear bridge. On the white bridge, the captain Bai Hua is directing his men to sail. The helm of Zhenhua Heavy Industry, Guan Lao, is also standing there, laughing. Hehe looked at the sea in the distance.

  "Guan Lao, we can carry out this task, we don't need you to come forward." Bai Hua looked at the white-haired Guan Lao with some emotion, at this age, can he stand the wind and waves at sea?

   Fortunately, our ship is fully loaded with more than 100,000 tons, so as long as there are not particularly strong winds and waves, the sailing will be very smooth.

"This is our maiden voyage after the completion of Zhenhua 3. It is the first time to carry out a mission. Mr. Qin gave us a big order of 40 million US dollars. We have to thank him well. Since Mr. Qin is at the accident site this time, Of course I have to go too." Guan Lao said.

  The $100 million rescue fee was split in half, and Da Mao should have taken advantage of it. After all, the cutting work was also done by Mingzhou Group, but Qin Tao didn't care about that much, and $50 million was enough.

   Keep 10 million as the cost of the Jiaolong, and Qin Tao gave the remaining 40 million to ZPMC.

  Guan felt touched in his heart! When Zhenhua Heavy Industries was still very weak and could not even open up the market, Mr. Qin gave them the opportunity to help them sell their cranes. After that, their cranes began to occupy the global market.

   Now, the crane ship Zhenhua No. 3 has just been built, and Mr. Qin has given them business again. Mr. Guan must come here to meet Mr. Qin and participate in the salvage with Mr. Qin!

Bai Hua didn't say anything, looking at the sea in the distance, at this moment, a voice rang through 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 tarmac."

The bridge behind Zhenhua No. 3 has a large area and can accommodate many people. In fact, it was originally a part of the cruise ship. It was not dismantled and used directly. There is a good-sized apron on the top of the rear. Make the big helicopters dock. In fact, looking at the area, vertical take-off and landing fighter jets are about the same.

   "Welcome! We welcome you warmly!" Mr. Guan said excitedly, "Now, immediately organize people to greet you on the tarmac!"

   After finishing speaking, Guan Lao was the first to run out.

  A Z-8 flew over. Compared with this huge apron, it seemed too small. After the helicopter landed smoothly, Qin Tao was the first to come out from it.

   "Guan Lao, are you too enthusiastic? Are there so many people?"

  Qin Tao looked at the two rows of people standing outside, there were twenty or thirty people, and these people were still holding flowers. It seems that the conditions on this boat are good, and they can grow flowers!

   "President Qin, no matter how grand this reception ceremony is, it can't be overstated!" Guan Lao said, "Our Zhenhua Group has benefited a lot from you."

"This is what should be done, you are welcome, you are welcome." After Qin Tao finished speaking, he looked at Nicholas who was walking behind him, and said, "Let me introduce to you, this is the person in charge of the salvage work. Nicola."

   "Welcome, welcome, would you like to have a meal in our cabin?"

   "No, let's take a look at this ship first." Popov said after coming down.

In the air, Popov was already drooling when he saw the ship, and now, standing on the helipad, looking at the huge boom in front of him, he was drooling with envy, 12,000 tons The lifting capacity is the only one in the world!

   "Okay, let me show you around. Let's go forward and walk to the front of the bridge, so that we can see our crane from the best perspective." Guan Lao was also very excited.

   "Excuse me, how did you develop such a large crane?" Popov asked as he followed.

Hearing the translated words, Mr. Guan said with a smile: "This is also necessary for our domestic construction and development. First of all, the hoisting and dismantling of offshore platforms, especially offshore drilling platforms and offshore wind farms. Generators require large cranes. The second is large-scale bridge projects. The deck hoisting of various bridges also requires large cranes. After having large cranes, we developed the concept of quickly salvaging sunken ships. "

  In the past, there was no relevant equipment, so special methods such as hanging buoys were needed to salvage. Now, with large cranes, the sunken ship can be lifted directly, and the salvage operation is more convenient.

   "How did you achieve this lifting capacity?" Popov asked.

   They planned to install 26 cranes on the barge for the first half of the salvage. Now, the huge monster in front of them can be used with only 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 the combination of two 6,000-ton cranes. You can see from here that it has two sets of parallel booms, and each set of booms can lift 6,000 tons. The combination of the two sets is 10,000 tons. The lifting capacity is 2,000 tons. Of course, we also made some reservations. In fact, if it is used to the limit, it will be no problem to lift 14,000 tons."

  Many manufacturers like to brag. They can only lift 800 tons, but they will boast that it is 1,000 tons. This shows that their company has strong technical strength. However, Zhenhua Group likes to keep a low profile and mark its lifting data smaller.

This is like building a car. Some car companies like to mark their engine data very large. It is often 200 horsepower, or even more than 200 horsepower. Well, the power of two hundred horsepower is less than one hundred and five horses at the wheels. And some luxury cars don’t need to rely on horsepower to pretend to be aggressive. They all like to have a low standard, with a standard of 180 horsepower. The power on the wheels tested is only high but not low.

   "Even if there are two cranes, 6,000 tons each is already against the sky. For example, how did the steel cables on it withstand such a heavy gravity?"

   "Our supplier can provide as much as it wants, and the arresting wire of our aircraft carrier is also provided by this supplier."

   Actually used the arresting cable technology of the aircraft carrier?

  It’s no wonder that the aircraft carrier’s arresting cable technology is the Everest of steel cables! Popov was very emotional.

  Actually, the arresting cable technology for the aircraft carrier is not as strong as the steel cable technology required by this kind of crane. The arresting cable provided by Juli is actually just a simplification of the steel cable technology, and it is not the best at all.

   "Our Kuznetsov also lacks arresting wires now." Nicholas said: "Qin, if I go to Moscow in the future, I will definitely purchase arresting wires from you."

The Kuznetsov aircraft carrier is assigned to the Northern Fleet, so Nikolai has not got his hands on it yet, even if he knows that the aircraft carrier lacks arresting wires, and the arresting wire manufacturer during the Red Empire has closed down, he cannot give Coordination, only in the future, when he becomes a higher leader, will he have this ability.

   "Of course, we will definitely sell it to you at the most favorable price." Qin Tao nodded: "If the third party wants it, we can also resell it through you, so that you can also make a fortune."

There was a smile on Nicholas's face. Of course he knew that Qin Tao was talking about Ah San. The Ah San Navy is currently ambitious to develop their aircraft carrier business. An aircraft carrier is also needed.

It is impossible for Ah San to purchase directly from the East, but it can be resold through Da Mao. Everyone can make money. You must know that the blocking cable is a consumable, and it has to be replaced every 100 landings. The supply of this thing is long-term of.

   "Why do they have such ships? In the East, our shipbuilding capabilities are the strongest!" A man with a mustache under his nose replied on a waiting ship.

"Yamamoto-kun, the Orientals have made rapid progress in the past few years. They have already monopolized half of the world's orders for natural gas ships. Their dredgers are even more outstanding. The crane ship in front of them is also the number one in the world. Our 30 Heavy Industry, we must face this point squarely. Your Changqi Shipyard is our main shipyard, you must work hard to develop, and you cannot let Mingzhou Group become the strongest shipbuilding group here!" Zeng, the person in charge of Sanling Heavy Industry Shan Xiongshou said.

Originally, 30 Heavy Industry was the strongest natural gas ship manufacturer in East Asia. However, they mainly manufactured Moss tank natural gas ships. , Now their orders are less and less.

   As for the dredgers, Mingzhou Group is even more powerful. It has built the most advanced dredgers in the world. Just look at the islands that appear in the southern waters, and you will know how unnatural this dredger is.

  The crane ship is right in front of you.

   How can we compare after this?

   "Technically, we may not be able to compare with them." Yamamoto Inutaro said.

"so what?"

   "So, we have to think of other ways, for example, we destroy a natural gas ship they made, and then promote their ships internationally as unreliable." Yamamoto Inutaro said.

   Broken? Unreliable?

Zengshan Xiongshou nodded: "Yes, Yamamoto-kun, this is a good way. The gas ship of Sanhang Heavy Industry leaked and Sanhang Heavy Industry completely disappeared. Now, we have to use the same method to make Mingzhou The group has completely disappeared!"

   If you can't compete with your competitors, then find ways to make your competitors notorious!

  The sun gradually fell, and the sea was once again shrouded in night.

  The fleet has converged, and 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 Bind them together so that they can withstand the tension of the steel cables. On the keel that cuts the fracture, we will drill 20 holes and fix 20 steel cables. If they are connected together, they can withstand enough tension. .”

If you have seen the tower crane lifting heavy objects, you should know that when the tower crane is hoisting, two hooks hang on each side, and then you can lift the heavy objects away, especially when lifting the prefabricated floor slabs before, it is directly hung on the In the round hole in the center of the floor, it looks like it can be unhooked at any time, but it is actually very safe.

  The current lifting plan is similar to hanging a floor slab, and it needs to be hung on both sides.

  Popov was only surprised.

This is a submarine with a displacement of 24,000 tons. At present, the torpedo compartment at the bow has been cut off, and it is divided into two parts from the rear. Therefore, the tail is about 10,000 tons. It is somewhat contrary to common sense to hoist the rear half of the submarine at both ends.

  Generally speaking, lifting should be done from both sides. In this way, the distance between the steel cables on both sides is only more than ten meters. What about now? It was lifted from front to back, and the distance between the two hooks was sixty to seventy meters!

  Can this be hoisted?

  What if during the lifting process, the center cannot bear the tension and breaks directly?

  Dangerous, 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 most stable." Qin Tao said: "After careful calculation, this lifting method will not cause any problems."

  If it is hoisted left and right, will this long object be subjected to uneven force from front to back during the hoisting process, causing it to be vertical instead of horizontal? This is going to be a big deal. Now, it will be fine to lift the front and rear, and the water will definitely come out smoothly.

  Nicolas nodded: "Since you have already calculated, then do it this way!"

   "Then we will finish drilling the Jiaolong tonight and make preparations for hoisting."

There are more than one group of operators on the Jiaolong. During this period of time, everyone is used to working in rotation. The Jiaolong did not have any problems in this high-intensity operation, which fully demonstrated the construction quality of the Jiaolong. Reliable and top-notch performance.

  When the eastern sky began to show a fish belly, the onlookers saw that Zhenhua 3 started to rotate the boom, which meant that it was about to be hoisted!

"The lifting quality of this kind of crane is enough, but it is not easy to lift a big guy with more than 10,000 tons from the water. The underwater undercurrent will affect it in various ways. The whole lifting process may be It will last for a few days, and maybe it will fail." Inutaro Yamamoto began to comment again: "If the salvage fails and the second half of the submarine falls again..."

"Then our entire sea area will be polluted." Zengshan Xiongshou said: "Although we want to see the Mingzhou Group make a fool of ourselves, we don't want to see this kind of accident happen. In this way, our fishery will be severely affected. Big hit, we're going to have a hard time selling our seafood, you know?"

  Yamamoto Inutaro nodded: "Yeah, **** it, why are they organizing exercises in this sea area?"

   "If you are not in this sea area, do you want to go to the Pacific Ocean?" Zengshan Xiongshou's eyes were gloomy: "That would be a worse news!"

   "Don't worry, we have eighty-eight fleets and are expanding into ninety fleets. What do the Easterners have? Their most advanced warships are still buying second-hand goods from Da Mao. They have nothing to fear."

   "No, no, they have already started building warships similar to Aegis..." Zengshan Xiongshou hadn't finished speaking, and looked into the distance: "The hook has already started to go down!"

  The huge runner is rotating, and the steel cables are constantly stretching out. The brackets at the front and rear of the crane are like the power towers of high-voltage lines, and the dense steel cables extend to the front hooks.

   Plop!

  The hook went into the water.

   I can’t see the hook anymore, I can only see that the steel cable is still extending, extending…

This process is long. Even if the speed of the hook is 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 put the hook down. .

  The sea water was beating against Zhenhua No. 3, and the 150,000-ton ship was steady and motionless.

   "They must have an advanced dynamic positioning system underwater, and it is fully automatic!" Looking at the operation of the crane ship from a distance, Inutaro Yamamoto began to analyze again.

  No matter how heavy the hull is, it will float with the flow of the ocean, but now, this crane ship is not moving at all, which shows that it is constantly adjusting its state, and it is dynamically adjusting.

  The requirements for this technology are very high. I really didn't expect that the Orientals could develop this technology!

  When hoisting at sea, if the crane ship shakes back and forth, it is very unfavorable to the lifting operation. It has to be the same as on land, and it cannot move. The crane ship in front of me has already done it.

  Others also saw it, especially the insiders, and they all began to think at this time: Maybe we can ask this crane ship to help us with some kind of operation in the future!

   While everyone was watching, the crane stopped moving, and the steel cable was finally let down!

   Then, there was another long wait, and it took a long time to hook up.

  The hydraulic motor on the crane made a new sizzling sound, and the steel cable began to be lifted up and down, and finally, the steel cable was all taut.

   It's been hoisted, it's about to be officially hoisted!

  In the sky, on a hovering helicopter, the camera lens is aimed at this place, and it keeps recording. This is the first time in the world that a submarine wreck of more than 10,000 tons has been lifted directly at a depth of more than 1,000 meters underwater!

  If it can be lifted successfully 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 with various special operations were blank in the East. In the past few years, the development of the East has been too fast. Has reached the world-class level!

  The crowds of onlookers had different moods.

   On the lifting boat, Nicholas was in a good mood.

   "The hook has been successfully hooked and the cable is tight, so what are you waiting for, let's start lifting now!" Nicholas said.

   "Yes, start lifting!"

  The monitoring screen on No. 908 was also transmitted in real time. On the monitor, the outline of the nuclear submarine could be seen indistinctly.

  Start lifting!

  The hydraulic motor of the crane continued to move, the cable went up, and the body of the big guy underwater also began to shake.

   Once, twice, three times, if the sound can be transmitted at this time, you will definitely hear the creaking sound!

  Finally, the figure of that big guy started to shake! After shaking for a couple of times, it began to turn slightly at an angle, and its stomach was no longer under resistance.

   Get up, get up!

  Nicolas held his breath, his heart was pounding, and whether he could successfully lift it depended on the hammer.

fine!

   There was no accident in the second half of the submarine, and it went up steadily. One meter, two meters, three meters, it left the bottom of the sea and was floating upwards!

   "Great, it's finally going to be salvaged!"

  Popov stood behind the two, both envious and apprehensive. They must salvage the first half, but what if the salvage fails?

  It took half an hour to release the hook, but it took a full two hours to lift the rear half of the entire submarine! The ascent of the sling was very slow. After all, there was a 10,000-ton man below. If it was too fast, if something unexpected happened, it would have dire consequences.

  The Jiaolong has been circling nearby, supervising the whole process of the underwater hoisting. With the pictures it sends back, it will be much safer.

   "If it is an attack nuclear submarine of less than 10,000 tons, wouldn't it be salvaged at once?" Someone expressed emotion.

"Of course."

   "Attention, it's coming out, it's coming out!"

  The tail of the huge nuclear submarine is exposed to the water, and it looks so spectacular. The largest underwater whale is only more than 30 meters long. The current underwater salvage section is 60 to 70 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!
