Great warships

Chapter 908 Mooring Test
After Qin Tao solved the problem in the Mo country, he returned to the Rainbow country, arranged for the production of follow-up ships, communicated with old friends in the Rainbow country, and finished the finishing work before returning to the motherland. When I returned to Mingzhou Shipyard, the design plan for an offshore oil and gas aircraft carrier had already been freshly released.

"President Qin, after several revisions, we have finally finalized the entire design plan of our ultra-deep water floating LNG ship." Yang Dawei reported to Qin Tao confidently: "The ship is 432 meters long and 66 meters wide. It is 38.5 meters high and has a total weight of 22 tons. It integrates underwater mining, natural gas liquefaction, storage and product export. When it is built, it will become the first in the world."

Qin Tao nodded with satisfaction. Originally, he just asked us to bring out an initial design drawing, and then he personally participated in the modification, but now it seems that this no longer requires his participation. It is perfect. The Mingzhou Group Design Department is so awesome. , fully equipped with independent research and development capabilities.

"However, such a big guy is also expensive, especially we plan to install our nuclear power Bora on it as the main source of power. In this case, the cost will exceed 50 billion yuan, and the price should catch up with the real aircraft carrier."

"Nuclear power treasure? Haven't you considered using natural gas as power?"

Different ships have to choose different power sources. Normal merchant ships generally use diesel engines, which are the most economical. Many ships transporting natural gas have already switched to using natural gas as power, so that the natural gas dissipated along the way can be used to reduce operating costs. cost.

Now this ship is a natural gas mining ship. Since there is no shortage of natural gas on it, it is best to use natural gas to provide energy.

"Yes, we have considered it, but this ship can only use natural gas as an energy source after the natural gas is extracted. During the process of driving along the way, and during the mining process, energy supply is required. Exploitation is full of many unknowns. It may be months, or even half a year, that natural gas cannot be extracted from the water. In this case, if the ship still uses natural gas as power, it means not only Not only is there no energy supply, but energy needs to be provided, and natural gas is not as convenient as fuel, so after various considerations, we do not think that using natural gas is a good choice.”

"It doesn't matter, just use natural gas. It will take us about a month to start the operation, and it will take about ten days to expand the working surface. As long as we can store the demand for natural gas for forty days, we can produce natural gas, and there will be a steady stream of natural gas in the future. Energy is supplied."

Butchers are never short of meat, and those who work in wineries are never short of alcohol. Their ship was originally used to mine natural gas under sea water. Of course, it must use local materials and use relevant energy to provide power, which is the most economical Well, the nuclear power treasure is not cheap, and it will have to be replaced after ten years, and this kind of offshore oil and gas aircraft carrier will take at least 30 years, and it will be even more wasteful to replace the nuclear power treasure twice in the middle.

At this time, everyone's eyes are on Qin Tao: can there be output in forty days?

"If this is the case, then we will be able to make a profit that year. After all, the annual production capacity of this ship is 330 million tons. According to the current price, it is about 2000 yuan per ton, so we can earn 66 billion a year. If we do not use nuclear power If so, then the cost of our ship can be controlled within 40 billion." Yang Dawei simply calculated.

Mr. Qin said that the natural gas can be extracted in ten days, which means that he is fully sure and knows where the oil and gas fields are. As for how Mr. Qin knows, they don't need to ask, as long as Mr. Qin knows.

The current price of natural gas is 2000 RMB per ton. This is because the demand for natural gas has not been released. After all, human beings’ awareness of environmental protection is fully increasing. The price of natural gas will soar in the future, and the purchase price will reach 4000 RMB per ton. In the hands of users, that is 7000 RMB per ton. This offshore oil and gas aircraft carrier can generate more than 100 billion annual income!
Even now, the big guys are surprised by the profitability of this project. Of course, the premise is that the natural gas can be produced in a short time. If you drill everywhere and get nothing, you will definitely lose money.

"It will take about ten days to modify the design. After ten days, we will start building this ship. It will take about two years to build this ship. After all, this is a ship that has never been built before. .”

Qin Tao nodded: "Consider this ship as our main civilian ship project, and prioritize the best workers to build it. After the ship is launched, we can start a new business, and there may be other customers in the future. If you come to us to order this kind of ship, then each ship will cost at least 40 billion yuan."

When the energy on land has been explored, people will inevitably look to the ocean. Mining on the seabed is much more difficult than on land. Our company is the only one that can produce natural gas on the seabed, and can also be directly liquefied, stored and transported. Factory, this kind of boat will definitely be liked by many users. Customers will definitely come to visit in the future, and they will be sold at a high price.

The amount remains unchanged, just convert RMB into US dollars. If you want to buy, you can buy it, if you don't, you can sell it.

The crowd nodded.

Even if the project is properly arranged, although Qin Tao can't wait to go to Mo country to mine natural gas immediately, but he doesn't have suitable mining equipment in hand, so he can only wait for the time being.Two years is not too much time. During this period of time, I can just pretend to let people know that I have gone through hard work and finally found natural gas resources from the coastline of Mozambique.If someone covets it in the future, then first settle the cost of this period of time. The exploration cost a total of 100 billion US dollars.

Time has entered October, which is the harvest season. When Qin Tao finished the meeting and came out, Muran found that the old man and a large group of naval leaders had a meeting in another conference room, Makarov and Babich were in it do report.

How is this going?

With curious thoughts, Qin Tao pushed open the door and sat gently on a chair near the door.

"At present, the outfitting has entered the finishing work. After analysis, we believe that the next mooring experiment can be carried out. Verify the performance of the aircraft carrier's main and auxiliary engines, verify the reliability of our ship-wide integrated power system, and complete the mooring experiment. Afterwards, the outfitting will also be completed simultaneously, and then the first sea trial can be carried out. Our power system is completely mature and reliable, so we are confident to complete the test of the aircraft carrier's power system and propulsion system."

Isn't this too fast?Qin Tao was shocked. Last time, the aircraft carrier was still outfitting, but now it is about to start the mooring experiment?The navy is too anxious!
At this time, Makarov, who was introducing, saw Qin Tao sitting at the door, and felt a little embarrassed: "Mr. I'm here to host."

"Who is in charge is secondary. The key is, under the current circumstances, are we sure to carry out the mooring experiment? What if something unexpected happens, for example, a certain circuit is not connected properly, resulting in an accidental fire?"

Warships catch fire from time to time during the construction process, and the most serious ones may even lead to complete damage to the warship. What should I do if I stumble and run in such a stride?
"We have already checked these, and the damage control system is in place. The remaining finishing work is mainly the installation of daily equipment in the living cabin, and does not involve the modification of any circuit parts. During this period, the internal wiring of the aircraft carrier has It has already been used, it just uses external power, and now it is necessary to transition to its own power generation." Makarov said: "In the final stage of outfitting, the ignition of the aircraft carrier's main engine is also a normal operation."

"You have to be sure. If something goes wrong, our Mingzhou Group can't afford the loss. The navy had better give us a waiver, because the navy is eager to urge us to start the mooring experiment during the outfitting stage. So if there are serious consequences, we will not be responsible."

Now it is the turn of the naval leaders to be in a dilemma, especially Wu Shengli, his face darkened immediately: "What do you mean? You want to play football for our navy? Believe it or not, our 003 aircraft carrier orders are given to other shipyards ?”

003 aircraft carrier?Qin Tao felt his eyelids start to beat. He started planning so soon?

Although the 002 aircraft carrier has been built, it is only a conventionally powered aircraft carrier after all, and there are many conservative aspects in the construction, and relevant technical reserves are also available. Therefore, the construction of the 003 aircraft carrier is only a matter of time, or a financial problem. , Look at when the finances will be allocated, then when will the work start.

"Ahem, dad, I just had concerns just now. Since our navy is not afraid, what is our shipyard afraid of? The funding for the 003 aircraft carrier has been approved?"

"There should be a tender next year. At that time, it may not necessarily fall into the pocket of your Mingzhou shipyard. There are many other shipyards looking forward to it." Wu Shengli said: "If this 002 aircraft carrier cannot meet the requirements of the navy The Navy has to think carefully about the construction of the 003 aircraft carrier."

"Next year, so soon?"

"That's right, the international situation is so complicated now that our navy has to resort to heavy forces to deal with various possible crises. Before bidding for the 003 aircraft carrier, the navy naturally hopes that the 002 aircraft carrier can complete sea trials and be finalized for service. Only the aircraft carrier will have confidence. Otherwise, why do you think the Navy would be so anxious?"

"We at Mingzhou Shipyard fully support it!" Qin Tao's attitude changed so quickly that the naval leaders present couldn't help but laugh.

Makarov also breathed a sigh of relief. As long as Mr. Qin supports it, there will be no problem with this project. Otherwise, if Mr. Qin doesn't sign, they won't be able to start the experiment. Who dares to take responsibility if something goes wrong.

This time, the Navy leadership officially proposed the 003 project, which excited Makarov even more. He already knew that Mingzhou Shipyard was preparing for it. Over the years, the nuclear power system has been perfected and a prototype reactor has been built On icebreakers, it can be said that the construction of nuclear-powered aircraft carriers has come naturally.He was also very excited when he thought that this kind of aircraft carrier could finally be comparable to the US-made aircraft carrier.

"Okay, then this mooring experiment can be officially started." Wu Shengli said: "Next, let's not take it here anymore, let's go to see the chimney of the 002 aircraft carrier smoke for the first time."

"Hey, why are you all so anxious!"

Qin Tao reluctantly followed the crowd to the outfitting pier. The scaffolding on the 002 aircraft carrier island had been dismantled, and all the electronic equipment outside had been installed. The majesty of the tiger makes people yearn for it.

Since they had been here last time, the naval leaders came to the engine room with ease. The 001 aircraft carrier has a total of five cabins, and the layout here is the same, one of which is dedicated to auxiliary machinery.

In the auxiliary engine room, naval engineers and shipyard technicians are already in place.

"Start the auxiliary engine first." Babich issued the first order.

There are a lot of preparatory work before the diesel engine is started, such as opening up the entire oil circuit, removing the air in the oil circuit, and first pumping oil with a hand oil pump. Now, after the order, everyone is busy.

The exhaust fan in the engine room whirred to take away some of the volatilized steam from the exhausted fuel. Ten minutes later, the preparations were over.

"Start the auxiliary machine!"

There was a chirping sound of compressed air.

Small diesel engines generally use electric start, that is, use a motor to drive the diesel engine to rotate, and then the diesel engine can work by itself, but there is no such possibility for large diesel engines. There is no motor that can bring it up, or in other words, The motors to turn it around are too big, and there aren't any batteries to power it.

Marine diesel engines are almost always started by compressed air. Compressed air enters the cylinders in the corresponding order to push the pistons, which can drive the giant to rotate. After it runs smoothly and injects fuel, it will start to rotate normally.

There was a feeling of vibration under the feet, and the buzzing sound echoed on the bulkhead. At this moment, the entire warship seemed to be excited, as if it had life.

"The chimney should be smoking now?" Wu Shengli said excitedly.

No one agreed with him, which made him a little curious: "Taozi, is the exhaust of this diesel engine too small to see the smoke?"

"Of course it can emit smoke, but the smoke from diesel generators does not go up the chimney."

Not going up the chimney?Wu Shengli was stunned: "Then where are we going?"

"Broadside discharge." Qin Tao said.

The chimney of the aircraft carrier is only for discharging the boiler. After all, it is the main engine, and the smoke is very large, but the auxiliary engine is not used. Just drill a hole above the waterline of the warship to discharge it. This can be seen from the side of some aircraft carriers that have sailed for several years. It can be found that some places are blackened.Especially the American aircraft carrier. After all, the American-made aircraft carrier uses nuclear power. There is no chimney on the ship island. Once the auxiliary generator is started, the smoke emitted will directly float out from the side.

Wu Shengli had a big oolong.

"Increase the speed!"

"The output is stable!"

"Increase to rated power!"

The vibration became more intense, and the sound became harsher. The technician shouted loudly: "Auxiliary No. [-] is operating normally, and the generator is already working!"

"Attention, prepare to switch the grid."

In the case of outfitting, the power of one diesel generator is enough to power the whole ship. Originally, the electricity delivered from the dock was used, but now it is time to switch for the first time!

The overhead light suddenly went out, and then suddenly turned on again, and it seemed to be brighter than before.

"The power switching is completed, and the power distribution system is working normally!"

"The No. [-] auxiliary engine was successfully tested!"

The crowd cheered.

"Is it time to burn the boiler next?" Wu Shengli asked.

"Not yet. First, we need to test the reliability of the auxiliary power to preheat the main oil pipeline." Babich said: "These are very important."

The auxiliary engine uses diesel oil. Under normal circumstances, an oil pump is enough, but the boiler uses heavy oil, which needs to be preheated. Although the original electricity of the shipyard can be used for preheating, it is impossible to test the performance of the auxiliary engine. .

"Fortunately, our shipyard is in the south. If it is in the north, during the outfitting process, the warship not only needs to provide electricity and ventilation, but also heating." Qin Tao said from the side: "Our shipyard has the advantage of building an aircraft carrier. It’s so big that other shipyards can’t compare.”

In Qin Tao’s time and space, when the 002 aircraft carrier was built in winter, green smoke would come out of the chimney. This is because of winter construction, the boiler must be fired in advance to warm up the internal cabin, otherwise the inside will freeze. Something may have to be reworked.

All the leaders held back their laughter. The Mingzhou Group has already built so many aircraft carriers, so the next domestic aircraft carrier must belong to the Mingzhou Group. Everyone knows it well, but if the Mingzhou Group thinks it must be their own, It's not okay to be arrogant. Leader Wu beat his son-in-law, and it seems that the effect is good.

There was a buzzing sound in the cabin, and I felt dizzy after listening to it for a while. One can imagine the working environment faced by the engineers who have been working here. After waiting for a while, Wu Shengli became a little impatient: "Let's go to the boiler room to see ?”

In the boiler room, there are also engineers busy. After the navy had the 001 aircraft carrier, it trained two sets of crew teams for this aircraft carrier. Now, although the aircraft carrier has not yet entered service, there is no shortage of skilled sailors.

The boilers of the two aircraft carriers are the same, and it is easy for the engineers to operate, and everything is done as usual.

When Wu Shengli walked in, he saw an engineer soldier helping another sailor put on a fire-fighting suit, covering his whole body.

"Is this going to be a fire?" Wu Shengli was excited.

Lighting the boiler is a technical job, and it is also very dangerous, so the preparations for the ignition must be done well.Generally speaking, the chief engineer is responsible for the ignition, carrying forward the fine tradition of Eastern soldiers: the leaders of dangerous places go first!

"Almost, the fire can be ignited in half an hour." The chief engineer, who had put on the fire-fighting suit, said, "Let's do some preparatory work first."

"Attention, the compressed air pressure has been restored, ready for blowpipe work!" At this moment, another order came.

"Understood! Blowpipe homework!"

"I know this." Wu Shengli just had a big oolong, but he doesn't care, he doesn't understand, neither do those who sit in the office in the yellow building, only the engineers and designers on the aircraft carrier understand, What a shame.

Now, he still knows this kind of pipe blowing operation, after all, this is the normal operation of the boiler power before it is first started.

Boiler power is very simple. Use the boiler to burn water into high-temperature and high-pressure steam, then enter the steam turbine, blow it on the blades, and push the blades to rotate. At the beginning, the air pressure is high, and the blowing is small blades. The most important thing is the large blade, and the steam turbine is such a combination of continuously increasing series blades.

If there are impurities in the airflow, the consequences are very serious: the impurities will hit the blades, damage the blades, or even break the blades!Once the blades in high-speed operation break, it will cause more terrible accidents, and even cause the entire steam turbine to be damaged.

Therefore, before starting the boiler system, a pipe blowing operation must be carried out. Although the inside of the pipe has been polished and smooth, there must be impurities in it. If you are unlucky, residual welding slag will fall. When pushed, it will be like a flying bullet!
So, you have to do blowpipe work to blow these things out.

Blowing pipes, of course, uses compressed air, and the high-pressure air used to start the auxiliary machine has this purpose. Just after starting the auxiliary machine, the lost compressed air has also been replenished, and now it is just used to blow the pipe.

The opening and closing valves of the pipelines were skillfully operated by the engineers. Following the completion of the commands one by one, the compressed air entered the interior of the pipeline with a bang, blowing out all the impurities along the way like the autumn wind sweeping the fallen leaves. When the exhaust port is discharged, all kinds of debris and impurities are densely packed everywhere.

"Blowpipe job done!"

"Attention, boiler No. [-] is igniting!"

The order to light the fire finally came!

Everyone had been looking forward to it for a long time. At this time, when they heard the order to ignite, they immediately looked at the chief engineer, but the chief engineer held a long ignition gun and began to chase people away: "Everyone, please go outside! "

The ignition operation is dangerous, and so many leaders must not be present. If the ignition is not successful and the flames are thrown out, there will be a big accident.

"Then open the door, let's see if it's okay?"

"No, according to safety regulations, the door must be closed."

As a result, all the people were isolated outside, and they couldn't see the operations inside at all.

You can only hear the passwords coming one by one.

"Open the diesel valve!"

"Fuel injection!"

"Successful ignition, furnace temperature rises!"

"Get ready to turn on the heavy oil pump!"

"Heavy oil was successfully ignited!"

The heavy oil ignites, which means the ignition is successful!

Outside, thick black smoke rose from the chimney of aircraft carrier 002 for the first time. When the heavy fuel oil was just ignited, the combustion was incomplete and the smoke was the thickest. The whole world declares: The main engine of the 002 aircraft carrier has been ignited, and the sea trial will officially start soon!
