"On the surface, the ro-ro ship is not very difficult. There is a living warehouse in the front, an engine room under the stern, and the remaining part is a cargo warehouse formed by a multi-layered fully connected deck. The entrance and exit are designed in the form of a springboard on the side of the ship or on the side of the ship.
The stern is convenient for ships to enter the cabin through the springboard. The overall ship is relatively fat, and its appearance is similar to an amphibious assault ship..."
When Zhao Ling said this, she suddenly stopped. She already understood why Brother Tao had no worries and agreed directly.
This kind of ship is used to hide troops from the people!
In the past few years, although the strength of the navy has been developing rapidly, in the eyes of the outside world, Dongfang's naval strength is still insufficient, especially the lack of amphibious landing capabilities. For Dongfang, if it wants to complete that sacred mission, it is impossible not to have this ability.
No way.
Although the Navy has begun to order 075, the quantity is not large. Compared with the huge transportation demand, it is still far behind.
Therefore, the famous RAND think tank has been denying Dongfang's landing warfare transportation capabilities, thinking that Dongfang does not have such combat capabilities at all. In fact, their understanding has a big problem.
They only considered military equipment and did not see that with the development of the shipbuilding industry in the East, there is also a large amount of civilian equipment, especially those ro-ro ships.
Ro-ro ships are used to carry cars, but of course they can also carry tanks and armored vehicles! An ordinary 10,000-ton ro-ro ship can carry dozens of tanks and armored vehicles to meet the transportation needs of an armored brigade, and this kind of
There are many ro-ro ships in the East! Among other things, the Bohai Ferry Company has 17 ro-ro ships with a total tonnage of 460,000 tons. Even if one ship can only carry 50 tanks and armored vehicles, this
That’s nearly a thousand pieces of equipment!
If it is really needed, as long as there is a safe dock opposite, civilian roll-on/roll-off ships can sail over. It is no problem to deliver thousands of equipment there at one time. How much equipment can be transported back and forth for a week?
The existing 071, 072, etc. in Dongfang are not large in number and cannot meet the needs, but these are all for the front station. As long as the front is open, the rolling fleet from behind will come!
Needless to say, even now, even in the 1980s, when the British fought that naval battle, they also used a large number of merchant ships, including ro-ro ships, to transport a large amount of weapons and equipment, which provided a huge contribution to the victory of the war.
of assistance.
"Brother Tao, we already have ro-ro ships of 10,000 to 20,000 tons in China. Do we still need to produce ro-ro ships of 40,000 tons?" Zhao Ling continued to ask.
Ro-ro ships are necessary, but are large ro-ro ships necessary?
Qin Tao nodded: "It is necessary. This level of ro-ro ship is no longer as simple as a ro-ro ship. The bottom can be equipped with tanks, armored vehicles, logistics supplies, and various personnel and equipment. The top... can also be made into a full
It’s flat and can be used for many purposes.”
If it is a ro-ro ship for both passengers and cargo, the top is more similar to a passenger ship, with several layers of cabins for passengers. The bottom is a place to park vehicles, so people can drive over, park their cars, and enjoy the scenery along the way.
Scenery, drive again when you reach your destination.
However, a ro-ro ship of tens of thousands of tons will definitely not be used for both passenger and cargo, and there will not be that many passengers. Many of these ro-ro ships are ordered by automobile manufacturers, and the produced cars will be shipped to their destinations, especially those that cross the border.
For ocean transportation, for example, if cars produced in Germany are shipped to the United States for sale, they must use this kind of ro-ro ship, which has few passengers on board.
If you want to build a passenger cabin, you can only build a few layers in the stern part of the ship, or only one layer in the bow is enough.
What about the rest?
The remaining uppermost deck is flat!
Isn't this straight deck an excellent landing platform for aircraft?
Forget about conventional takeoff and landing, let alone electromagnetic catapult. There is no ski jump to the deck, but vertical takeoff and landing fighter jets can be used!
During the Falklands War, the British Navy did not have many aircraft carriers on hand, but they modified a large number of civilian ships to transport their Sea Harrier fighter jets or helicopters. When needed, a circle of containers was placed outside with sea carriers inside.
Harrier can take off and land skillfully!
The East already has vertical take-off and landing fighter jets like the J-31A. Although they are currently used on islands, in the future amphibious assault ships will definitely need to be equipped, and large ro-ro ships can also be used!
Vertical take-off and landing fighter jets do not have a big impact on the deck. When designing a ro-ro ship, as long as the deck level is improved, it can be converted to military use in the future.
Even if the J-31A cannot be used, the drone can also be used.
There are already a large number of drones in the East, and there is an entire industrial chain. Even civilian drones can be strapped with bombs and launched into the sky when needed. Looking at the battlefields of later generations, this kind of thing is not uncommon.
The upper deck of the ro-ro ship can easily take off and land the drone, which plays a good supporting role.
"The area of the top deck of a ro-ro ship of 10,000 to 20,000 tons is not large enough and it is inconvenient to take off and land aircraft. When it develops to 40,000 tons, it will be very convenient to take off and land aircraft and drones. In normal times, it is economic development.
A good helper. When needed, it can transform into a mothership at any time, carrying vertical take-off and landing fighter jets, helicopters and drones, and tanks and armored vehicles underneath." Qin Tao said: "So, we need a new 40,000-ton class.
Ro-Ro ship, if our brother units don’t have the capability, then let’s do it!”
Mingzhou Group has not built ro-ro ships yet, but other brother units have. This time, foreign customers came to them and did not go to other shipyards. There is obviously a reason.
"Other brother units felt that the tonnage was too large and difficult to build. Moreover, if there was an accident, the ship owner would claim compensation, so they did not dare to undertake it. The ship owner found us. Of course, there is another situation.
, there may be pitfalls here.”
This chapter is not over yet, please click on the next page to continue reading! Accepting shipbuilding orders from abroad is not necessarily a good thing. Take a look at South Kimchi Country's Line Heavy Industry. Isn't it just because they can't build the order after taking the order, and then they lose everything?
?Now that the entire line generation heavy industry has been acquired by an American company, the South Kimchi Country no longer has a large shipyard of its own.
This time, the order was not from China, but from Norway. Instead of choosing a European shipyard, they came to Dongfang and Mingzhou Group. Are there any problems?
Qin Tao smiled: "What other pitfalls can there be? We won't sign harsh compensation clauses like Line Dai Heavy Industry. They came to us just because Europe can't build this kind of ship. Let's go to Huating and let's go together
Meet European customers.”
Is Europe strong?
It used to be really strong, but now, Europe has declined. It has declined to the point that many ship types are no longer dared to touch it. They don't have the technology!
At present, the ro-ro ships in the world are all between 10,000 and 20,000 tons. This is the first time for a 40,000-ton ro-ro ship. Europeans do not have this technology, and they dare not touch it for fear of danger. The former 100,000-ton ro-ro ship
This is what happened to the first-class bulk carriers. After they were built, they broke off in the ocean. However, the bulk carriers built by Mingzhou Group have been running smoothly. Mingzhou Group is the most advanced shipbuilding company in the world. Of course, it also wants to build the world's most advanced shipbuilding companies.
Advanced ship model!
These 40,000 tons were actually not that big. In later generations, the island nation's Mitsubishi Heavy Industries once built a 75,000-ton roll-on roll-off ship for the Wilson Company, with a load capacity of up to 43,000 tons. This company was also owned by Norway.
Now, they just want to go to the East to purchase a suitable ro-ro ship. At this time, they can develop a ro-ro ship of this level. The country will definitely need it. By then, they will produce a batch of them for civilian use.
When necessary, it should be regarded as a contribution to the military.
With this idea in mind, Qin Tao and Zhao Ling stayed in the capital for one night and headed to Huating the next day. The Norwegian shipowner was still waiting in Huating.
Cong Ju worked hard at the Huating Second Shipyard, leading the shipyard to grow and develop. She would not trouble Qin Tao to come over for ordinary matters. She was still a little embarrassed to see Qin Tao this time, but there were guests around.
She couldn't show any apology either.
"Mr. Qin, let me introduce to you, this is Mr. Andreas, the person in charge of the Revelino Group." Cong Ju introduced everyone in fluent English: "Mr. Andreas, this is Mr. Andreas.
Mr. Qin of our group."
The Revelino Group is a company specializing in international freight. It was established in Norway in 1927 by Refuleno, who was thirty years old at the time. At that time, he saw the demand for oil transportation and established a company to transport oil. Now,
With the development of the times, the company's main business has changed from oil to liquefied natural gas and other cargo transportation.
By 2006, the group will split into two independent entities: Lenno Shipping and Lenno LNG, which are still together now.
Since we want to transport LNG, we inevitably need to deal with Dongfang. They originally came to order LNG ships, but this was their third order. After coming to Cong Ju, they suddenly mentioned that they wanted to order 8500CEU, which is
A roll-on/roll-off ship capable of transporting 8,500 cars, but after asking shipyards all over the world, no shipyard dared to accept it, so I asked Cong Ju if it could be built here, but Cong Ju couldn't commit immediately.
, so I reported to Mr. Qin.
Now, Mr. Qin is here, and Andreas is very excited. He has a premonition that there will be new gains from this meeting.
"Mr. Andreas, it's a pleasure to meet you." Qin Tao said: "We noticed that in your shipping business, you mainly operate ro-ro ships, and you also order larger ships. Do you think you are interested in this?
Is the market very promising? As far as I know, transporting cars does not necessarily require a roll-on/roll-off ship, containers can also be used."
If you buy a foreign car, you can see the 4S store opening the container and driving the car out. Compared to roll-on-roll-off ships that can only transport cars, containers seem to be more common.
Not to mention cars, even a large truck can be dismantled into several parts, stuffed into containers, and then reassembled at the destination.
How big is the market? Do customers need to dedicate their vessels?
"Yes, the world is developing, the economy is recovering, and there is a huge demand for cars around the world. We know that there will not be a single car in any country's market. Our European cars will be sold to the United States, and American cars will also be sold.
It will be sold to Europe. Our ships are fully loaded back and forth. We have felt that the existing shipping capacity is insufficient, so we need larger ro-ro ships." Andreas said: "We think that if we can build
The transportation efficiency of the 8500ECU ro-ro ship will be further improved. However, this kind of ship is too difficult. Each deck needs to be empty, and there cannot be pillars inside. Many shipyards feel that increasing the displacement will make it more fragile, which may
It will threaten the safety of navigation. We know that Mingzhou Shipyard is good at building ships that others cannot build. The 100,000-ton bulk carrier you built is an example. We hope you can help us build such ships."
The cabins of ordinary cargo ships are all equipped with partitions. Even if it is a huge oil tanker, partitions can be used to strengthen the ship. However, this is not possible for ro-ro ships. If the cabins are separated inside, it will cause serious waste of space and reduce
The transportation volume of automobiles must be carried out to the end!
This requirement is very similar to the hangar of an aircraft carrier. Therefore, although others cannot build it, Mingzhou Group has no problem building such a big thing!
"With this kind of carrying capacity, plus the weight of the ship itself, the full load displacement will reach 40,000 tons, which is very similar to our 075. Therefore, if you want to order, we will modify the 075 hull to meet the requirements.
Loading requirements.”
This chapter is not over yet, please click on the next page to continue reading the exciting content! Don’t say anything else, just move out the 40,000-ton 075!
"Ahem." Andreas was startled: "Mr. Qin, we don't need an aircraft carrier or an amphibious assault ship, and if the cost is too high, we may not be able to afford it."
Qin Tao smiled: "Of course it will not reach the construction cost of an aircraft carrier. I just said that according to the design of 075, many internal standards are still civilian ship standards. We will reasonably control the cost. Let me introduce the general plan first."
The hull below is actually the same as the 075. When it comes to the top, the hull also expands and the cross-section becomes a rectangle, which naturally maximizes the load capacity. The top becomes a rectangular box, like
It's an extra-large pencil case.
This ship type looks strange, but it is the only way it can meet the loading demand.
"From bottom to top, we designed a total of fourteen decks, which can provide a total of more than 70,000 square meters of deck space for loading various vehicles. These decks are all connected, just like the hangar of an aircraft carrier. The main issue is strength.
Solve it through the transverse deck." Although the time is short, Mingzhou Group has already produced a preliminary design plan, which fully reflects their expertise in this field.
They are all a single deck with no columns. How to solve the strength problem? Will it collapse if cars are loaded in layer by layer?
Of course not! There are many tricks in this. Why didn’t the aircraft carrier’s hangar collapse? Just use the design of the aircraft carrier’s hangar.
Although there is no longitudinal support, there is horizontal support. As long as it is fixed to the side of the ship and relies on high-strength steel plates, it can be supported.
Only shipyards that build aircraft carriers dare to do this.
Andreas nodded, very satisfied with this design. He didn't know the strength, but everything inside was straight through without any pillars. This was the most important thing.
"Among them, the five decks in the middle are movable." Qin Tao continued: "They are made to lift and move up and down. In this way, the ro-ro ship can not only load cars, but also trucks.
It can even load yachts or large agricultural equipment when needed, increasing the diversity of your transported goods."
With more layers, the height of each layer is limited. If you want to install a car, two meters is enough. Even if you want to install some tall and powerful off-road vehicles, it can be two meters high, up to two meters.
5. However, this height is not enough for loading trucks.
What should I do if I want to install it on other vehicles?
The answer is that the deck can move up and down!
This is a brand new design! This design improves the flexibility of transportation and allows them to take on more transportation business!
The reason why they are on the middle floors is of course because the bridges connecting the ro-ro ship and the wharf are on the middle floors. The heights are the same, making it easy for vehicles to enter and exit. Cars can be loaded up and down. The middle floors are installed last and the height can be changed.
It is no problem to install large items, especially the layer where the bridge plate is built, and finally install those super high items.
"Can such a large deck be moved? How is it possible?"
"This is equivalent to a large aircraft carrier elevator." Qin Tao said, "We have this technology."
Qin Tao has been repeatedly instilling this truth: To build a ro-ro ship of this level requires aircraft carrier technology. The direct access deck below is the hangar of the aircraft carrier. This elevator is also a technology used by aircraft carriers.
An aircraft carrier needs an elevator so that it can complete the transfer of aircraft on and off. Moreover, similar to the super aircraft carriers in the United States, one elevator can accommodate two aircraft at the same time. Even two large bugs weigh more than fifty tons. If two Tomcats
, more than sixty tons properly, plus its own weight and various redundancies, the aircraft carrier elevator needs to have a take-off and landing capacity of one hundred tons, so that it is safe enough.
This is the aircraft carrier's elevator. What about other elevators?
Moving the entire deck up and down is equivalent to multiple lifts moving at the same time. Of course, you cannot put cars in when moving. You have to move it without load. That is to move the entire deck, which weighs about 500 tons.
It's about the same as five aircraft carrier lifts, so it's not that difficult. Moreover, Dongfang also has the world's most powerful cranes, so it's not easy to do this.
Qin Tao doesn't think it's that difficult. The super ro-ro ships of later generations also have this design. Now that he has come up with it, it is the first of its kind. This is what Mingzhou Group wants!
"Mr. Qin, it's true that we found the wrong builder. If it can be designed like this, we will be able to transport more types of goods. Your design is great!" Andreas was very excited.
"Well, let's move on to other aspects. Regarding the engine, what engine do you plan to use?"
