After talking about the hull, the next step is the engine. For civilian ships, it doesn’t matter if the speed is slower. There is no rush anyway, the key is to save fuel! What you save is what you earn.
“Just use ordinary marine diesel engines.” Andreas said: “We have purchased three batches of liquefied gas ships from you, and the engines used on them are very good. We have confidence in your engines!”
“Do you want to use a new power system?” Qin Tao asked.
A new power system? Andreas frowned. For them, they really don’t want to engage in any innovation. Stability is the best. Look at the Kimchi Country. The pursuit of innovation will end up overturning, right?
What other brand-new power systems can be found in the East?
In addition to diesel engines, there are also gas turbines. Does the other party want to let us use gas turbines? That thing burns too much oil!
"Ro-Ro ships are a special kind of ship. You won't put anything on the top deck, and it would be a waste to leave it empty." Qin Tao said: "We have a design here that can install 4,000 square meters of solar energy on the deck. The battery panels can provide 5,000 kilowatt-hours of electricity per day under good lighting conditions. This electricity can not only satisfy the lighting inside the cargo hold, but also provide forward power for the ship, making our ships more environmentally friendly."
Mingzhou Group is serious about environmental protection. They want to build solar-powered cargo ships!
This is not surprising. As environmental protection slogans become more and more popular, many cargo ships have begun to use solar energy. However, generally speaking, the solar energy of cargo ships is used to supply lighting and air conditioning systems, and there is no direct drive for ships.
After all, it takes a lot of solar energy to power a ship.
The deck area of the 075 is 7,800 square meters. If it is converted into a ro-ro ship, some deck area will be wasted. Qin Tao calculated that it is good to be able to install 4,000 square meters of solar energy. In this way, the generated power will be enough to drive the ship forward, or provide part of the electricity, and then the ship's own power will provide the other part. If you are not pursuing speed, then use solar energy to sail slowly.
In later generations, the 60,000-ton ro-ro ship "Auriga Leader" manufactured by the island country used this method and installed a large number of solar panels to drive the ship forward and reduce the ship's fuel consumption.
"According to our calculations, even if there is only four hours of sunlight a day, ten tons of fuel consumption can be reduced. If a voyage takes forty days, it can save four hundred tons of fuel consumption. If used in low latitudes, You will save more fuel." Qin Tao said: "It not only protects the environment, but also reduces transportation costs. It is your best choice. It depends on whether you are willing to be the first to eat crabs."
In the past, ships only used solar energy for lighting and air conditioning, not for driving. This is of course because the previous ships were directly driven by the engine. If it was a low-speed diesel engine, it did not even use a reducer, and directly used the engine through the transmission shaft. To drive the propeller, reversing can be achieved by reversing the engine.
In this case, even if electricity is generated, power will not be used.
If you want to use solar energy to drive it, it means modifying the power system. The engine drives the motor to generate electricity, and the generated electricity drives the tail motor. In this way, the solar power can be connected. This is called a ship-wide integrated power system. .
This system, Mingzhou Group already has a civilian version.
“How much more will it cost to renovate like this?”
“Not much, we can definitely get it done with thirty million dollars.”
Andreas shook his head like a rattle in an instant: "Forget it, it will take hundreds of thousands of tons of oil to replace it. It's not worth it."
The cost of this thing needs to be calculated. After installing this kind of system, you can save fuel, but you also have to see how much fuel is saved and whether the two sides are directly proportional. This is just like electric cars. People who like them shout out to themselves every day. It only costs a few cents per kilometer, not to mention the tens of thousands of dollars more spent when buying the car. These tens of thousands of dollars can burn fuel for several years. When a few years pass and the battery performance declines, what kind of expense will it be.
Qin Tao wants to trick the other party into using this special system, and the other party also has to calculate the cost. A simple calculation will tell that it is not cost-effective, so why use it? Wouldn't it be better to just burn oil?
“The temporary investment is a bit high, but solar energy is an environmentally friendly energy. Using solar energy can reduce tail gas emissions. We only have one earth, and we must take care of our own earth.”
Andreas looked at Qin Tao with a meaningful look: "Mr. Qin, let's talk about something practical."
Qin Tao was a little helpless. His promotion was not successful, and the other party was unmoved. Don’t you Europeans shout environmental protection slogans every day? It seems that it is still for ordinary people to see. For these capitalists, they don’t care about **** environmental protection, they only care about their own interests.
All right.
"Let's go on to talk about the most important system on this ship." Qin Tao said: "Ro-ro ships are a special kind of ship. They are very particular about loading and unloading. If the balance cannot be maintained, it may cause the ship to capsize. .”
This is just like a viaduct. Many viaducts are single-column, so the cost is low. Then, several heavy trucks occupy one lane side by side, driving happily, and then suddenly there is a click, the world spins, and the single-column viaduct The bridge deck turned into a seesaw and was crushed over!
The loading of oil tankers, bulk carriers, natural gas ships, etc. is all balanced loading. For those flowing liquids or solids, it is impossible to be particularly biased.
However, this is not necessarily the case for ro-ro ships. Ro-ro ships are used to carry vehicles. If one side is loaded with cars and the other side is loaded with SUVs, the center of gravity will definitely shift to one side. When it reaches the sea, it may overturn when encountering wind and waves.
Therefore, you must be careful when loading and unloading cargo on ro-ro ships, and you must also pay attention when sailing out to sea.
So, is there a way to solve this problem?
Since Mingzhou Group has taken action, of course it has a solution to the problem!
“We will develop a special system that can monitor the loading status of the ship at all times, judge the deviation of the ship’s center of gravity, and alarm if it exceeds too much.”
This monitoring system is not difficult. For ships, it is enough to monitor the ship's draft. Different ship sides have different draft conditions, so it can be monitored naturally. Sensors can also be set up on the deck to detect even a slight inclination. The upper deck will also maximize this tilt. It can also be the top mast, with a level gauge installed on it, etc., which can be monitored. Modern technical conditions are not difficult to solve this problem.
With this system, loading and unloading of ro-ro ships will be much safer!
"At the same time, we will spray paint from the aircraft carrier deck to the deck to maximize the friction coefficient of the deck. At the same time, we will also transplant the rigging devices. After each vehicle is placed on the deck, if necessary, It can be fixed quickly. This can reduce the possibility of vehicle movement in high sea conditions and ensure safety."
ro-ro ships are used to load cars. The cars are on the ground and can be fixed directly by handbrakes. But what about on the ship?
The ship is shaking, and if the swing is too large, the cars may slide on it, which will have a more terrible reaction: the ship tilts to one side, and all the cars loaded on it also tilt to this side, and then Just Barbie q.
When cars are transported by road, each one will be tied tightly to the car, but if they are tied one by one on the ship, it will be a huge amount of labor, which is not something ordinary crew members can bear.
8,500 vehicles, each with four wheels, fixed four times. How many times does it take a dozen or even a hundred crew members on a ship to do this?
This kind of ship designed by Mingzhou Group will spray aircraft carrier deck paint on the deck. This paint has a high friction coefficient and can keep the car firmly in place. It can be **** when needed, or it can be loaded onto the ship first. , bundle them one by one slowly to save time.
"In addition to these, we will also use a complex fully automatic counterweight system on the ship." Qin Tao continued to introduce, which made Andreas open his eyes wide and could only listen. It can't be turned around at all.
Fully automatic counterweight system?
"At the bottom of the cabin, we will design a dual-track system. A 22-ton counterweight trolley will move on this track under computer control to dynamically offset the change in the ship's center of gravity. At the same time, when it is at sea, it will also It counteracts the rolling and pitching caused by the lapping of waves, allowing the ship to run more smoothly." It's very lofty. In fact, this is a common anti-rolling system on warships, almost a replica of the Charles de Gaulle.
The displacement of the Charles de Gaulle is only 40,000 tons. In order to increase the number of aircraft loaded, the deck area is large and there is a lot of external drift, which makes the warship sail unstable. In order to allow the Charles de Gaulle to have sufficient stability in high sea conditions, For the take-off and landing operations of carrier-based aircraft, they carefully designed the anti-rolling system.
In addition to the active stabilizer fins, there is also a complex fully automatic anti-roll system, which uses the principle mentioned by Qin Tao. Even though the car is only 22 tons, it can fully meet the needs of stabilizing the warship with four or two pounds of weight.
Here, of course, the ro-ro ship can also be stabilized.
Other ships don't use it, they just sway. If this ro-ro ship sways too much, something big might happen. Therefore, many means are needed. Ordinary shipyards dare not take it on. It's because they don't have these technologies. Mingzhou Group They build aircraft carriers. If they take the equipment from the aircraft carrier and put it on civilian ships, the effect will be just right.
At this time, when talking about these things, they were all high-end things. Andreas's eyes almost popped out when he heard them. Their group focused on the ro-ro ship business, and they thought they were the most familiar with ro-ro ships. The shipper, I didn’t expect that everything I heard from Mr. Qin was new and unheard of!
Mr. Qin is so awesome!
"Mr. Qin, we should have come to you for help a long time ago. Although you have never built a ro-ro ship, you have built countless aircraft carriers. Your experience is the richest. We believe in your ability. By the way, such a ship How much does a ro-ro ship cost?”
“Three hundred million U.S. dollars.” Qin Tao said.
Three hundred million!
Andreas's eyes popped out: "Mr. Qin, why is it so expensive? It's more expensive than a liquefied gas ship!"
The tonnage of the liquefied gas ship is larger, and the liquefied gas ship also needs to use expensive invar steel. In this way, it only costs more than 200 million US dollars to build one. What about this ro-ro ship? The tonnage is only half that of a liquefied gas ship, and it doesn’t need expensive Invar steel. Why does it need so much money?
"Yes, the technical content of the ro-ro ship is not lower than that of the liquefied gas ship. Although it does not require Invar steel, it does need high-strength steel for the construction of aircraft carriers." Qin Tao explained: "We designed 15 layers The deck, the upper five decks need to use high-strength steel such as aircraft carrier deck steel in order to reduce the weight and center of gravity. Everyone, can you calculate how much it costs just for these steels?"
Aircraft carrier deck steel is a special kind of steel that can withstand the huge impact of a carrier-based aircraft landing. It must also be thin. If it is thicker, the deck will be too heavy and the center of gravity will shift upward, making the aircraft carrier unstable.
Countries in the world that can produce aircraft carrier deck steel can be counted on one hand. Only these countries can build modern aircraft carriers, and only these countries can build modern ro-ro ships!
The ro-ro ship has fifteen decks. The lower layers can be made of ordinary steel. It doesn’t matter if it is thicker. It is even better to be thicker. This way, the bottom deck is heavy and it is stable to drive, but the upper deck must be light. The lighter the better, aircraft carrier deck steel is the most suitable!
Even if only five layers of this steel are used, the price is astronomical! These five floors are worth 100 million! Of course, the 100 million is not the cost, but the purchase price. If you don’t believe it, you can ask Asan to see how much they spend on purchasing aircraft carrier deck steel.
"At the same time, a lot of advanced technologies are used in this. I have just introduced it to you. Those technologies are all used on modern aircraft carriers. The price is not low in the first place. These new technologies are worth 100 million. You What do you say?"
The deck steel is 100 million, the new technology is 100 million, and the remaining hull is 100 million. The other party only plans to buy the ordinary hull, which is of course not enough!
"So, 300 million has been spent, and it won't be much to spend another 30 million. I suggest you go to the high-end version and put solar panels on it. It's so high-end!" Qin Tao said: "Drive out, and you will be the thunder. The face of Fulino Group, let the whole world know that you are at the forefront of the world in the field of environmental protection, and you are already the well-deserved leader in the field of ro-ro ships!"
Such words are useless. Andreas is already an experienced veteran. How could he be fooled by Qin Tao's words? All he could think about was the price.
Three hundred million!
The existing ro-ro ships with a loading capacity of 10,000 tons can be ordered for less than 100 million. If the loading capacity is doubled, the price will more than triple. Is this a good deal?
Go to other shipyards and ask? No other shipyard can build this kind of ship. They are all afraid of an accident. The compensation will be enough to drink a pot of it. The precedent of Cable Heavy Industry is there. They would rather not make money than lose money. They will pay. Sorry.
“Mr. Qin, how many years of maintenance period can you promise for this ro-ro ship you built? If an accident occurs, do you promise to compensate?” Thinking of this, Andreas asked.
"Accident? Compensation?" Qin Tao rolled his eyes at Andreas: "This is an insult to our Mingzhou Group! Mr. Andreas, you can see that our Mingzhou Group has built so many ships. Have you ever seen any ship that had quality problems? Our Mingzhou Group can promise that the ship we built will have no problems! It is only a shipyard that has no confidence to agree on compensation clauses in the contract. We will never agree to it. Such terms."
Andreas was embarrassed.
Mingzhou Group has continuous orders, and there is no need to go to the international market to grab orders. The shipbuilding process is watched by shipowner representatives, and there are no quality problems at all, so there is never a compensation clause in their contract!
Only a shipyard that has no idea will sign a compensation clause! We won't!
“Of course, our Mingzhou Group has its own insurance company. If you feel unsure, you can come to our insurance company for insurance. Our insurance company is also very welcoming. After all, this is a profitable business.”
We do not pay compensation, the insurance company is responsible for the compensation! Qin Tao has made it very clear.
Andreas's mind was a little confused, and he didn't know what to choose.
Mingzhou Group has always been so strong. After all, they have unique skills, but their prices are too expensive and not cost-effective at all. If you order here, you will be a bit taken advantage of. However, after some analysis, their company believes that this level of sales The transportation efficiency of shipping will be higher, and Mingzhou Group has also promised a variety of advanced technologies. The addition of these technologies is also very exciting.
Qin Tao looked at the opponent's dilemma and threw Wang Zha.
"Actually, a 40,000-ton ro-ro ship is not very efficient. This is just the beginning. In the future, you may need a 60,000-ton or even 80,000-ton ro-ro ship. The larger the ship, the more it can be transported in a single trip. The more equipment there is, the more crew members there are. Although the procurement cost is high, as long as the operation efficiency is high, the cost can be recovered quickly. If we don’t take this step, we will always be stuck at the same level of transportation efficiency in the past.” After Qin Tao finished speaking, he stood up: "Mr. Andreas, I hope you will consider it carefully and see what is the best choice."
Forty thousand tons is nothing. In the future, we will need 60,000 tons or 80,000 tons ro-ro ships. If you don’t take this step now, how can you continue to develop in the future? We are the only ones who can build this kind of ship!
“If you think it is expensive, you can contact your country and ask them to provide some funds.”
State funding? How can it be? The government of South Korea likes to allocate funds to its subordinate enterprises to support their development. We do not have such preferential treatment. If the country allocates funds to us, what will other companies say? Those who clamor for environmental protection every day will stand up immediately and demand that money be spent on environmental protection!
However, Qin Tao had already stood up and walked outside at this time.
“When you think about it, you can come back to our Mingzhou Group at any time! The quotation will not change within one year!”
