"When will you leave?"
In the office, An Ning was full of reluctance when he heard that Li Fanyu was going to East Pacific in person. An Ning's mood has changed a lot recently. Sometimes she loses her temper with Li Fanyu, but she often clings to him like a child.
Li Fanyu quietly touched her hair and said, "This time is different. If I go there, I will just see the underwater construction conditions. It is mainly to collect data for the first field operation of the robotic arm in a harsh environment. . If there are no problems, Liu Qing and the others can do the work, and I will be back in a few days. "
An Ning nodded and then said with relief, "Then come back as soon as possible."
Seeing her suddenly clinging to him, Li Fan smiled foolishly, "If you say you can't live without me and I can't even think about not seeing you for a day, then I don't have to go!"
"Bah!" An Ning gouged out his eyes, "Smelly, I don't care whether you want to leave or not!"
Li Fanyu shook his head helplessly, not understanding what this woman wanted,
After receiving another urging call from Liu Qing, Li Fanyu hugged An Ning, and after a few words of advice, he walked downstairs and took a car to the Zhengxin Port next to the industrial base.
Liu Qing and others have finished loading the ship and are waiting for him to board the ship and leave.
In the past ten days, Zhengxin completed the modification of the working arms of fifteen Jiaolongs as quickly as possible, and spent another five days testing them off the coast of Tiancheng. However, due to environmental constraints, Liu Qing They only did a simulation test of 5,000 meters under the sea and an actual environmental test of 2,500 meters under the sea. Everyone is still very cautious about the working conditions of the 5,000-meter underwater.
That’s why Li Fanyu, the chief designer, and technical backbones such as Liu Qing were required to follow up and bring a large number of spare parts and maintenance facilities. We strive to ensure that any problems encountered when the robotic arm works underwater can be solved at any time.
The whole world knows that these new technologies of Zhengxin are very expensive.
However, all users of Zhengxin Power are particularly satisfied with the technical support and services provided before, during and after the sale!
Almost all Zhengxin Power products, whether it is a large ship engine, a 1911 general engineering platform, or a field mouse digger, after all products are sold and delivered, Zhengxin will sell them for diamonds. Our team followed up for a while. No matter which country the user is from or the size of the user's order.
On the one hand, it collects the matching of use and other supporting facilities. On the other hand, Zhengxin’s team will also provide complete technical support to ensure that there will be no problems after the product is put into use.
It is precisely because of this strong service and technical support that the current products of Zhengxin Power are the best-selling among all products of the same level.
This is even more true this time when we reached an order with the Bureau of Ocean Exploration.
After intense negotiations, the Bureau of Ocean Exploration agreed to pay 1.5 billion in advance and guaranteed that if the manganese nodule mining area in the East Pacific Ocean is successfully mined, Zhengxin will provide Zhengxin with a ten-year supply of rare metals produced at the cost price. .
In fact, this agreement would definitely not be passed in normal times, but in order to let Zhengxin contribute, the higher-ups accepted it after research.
After all, there is less than half a year left in the current mining period. If the project cannot be completed by the deadline, it is not time to sacrifice this little profit!
The special cargo ship carrying Li Fanyu and others and more than a dozen Jiaolongs headed towards the Eastern Pacific Ocean at maximum speed.
The giant ship is working overtime at sea. In the activity room of the ship's cabin, Zhengxin's technical staff are also enthusiastically accepting the project breakdown and technical key points explanation from CNOOC and the Bureau of Ocean Exploration.
"In the seabed mining project, we need to consider the impact of seabed minerals by seawater and sedimentary biological resources. What we originally prepared was to use a low-efficiency, but it is also the simplest way to mine deep-sea manganese nodule minerals, that is, a single ship. Bucket type. However, this housing mortgage was submitted to the International Marine Association and was not approved. According to the requirements of the International Seabed Resources Association and the Marine Association, seabed mining must take into account the impact of the mining process on marine life and renewable resources. Therefore, we can only. Forced to adopt the current international mainstream CLB-II deep sea mining solution. ”
“This mining plan is also a hydraulic lifting plan, which requires us to have one or more seabed mining devices, a corresponding number of ore lifting equipment, large towing ships, and at least two offshore operating platforms. ! ”
“We have spent 12 billion from Russia to customize three sets of the most advanced Ikimir-type ultra-large suction mining ships designed by the Moscow Mining Institute and produced by Ulyan Shipyard. It is equipped with a set of water conservancy improvement equipment developed by the scientific research unit of our bureau. This is our drawing, please take a look. ”
When they saw the large ship on the slide that was not much inferior to the Jingwei, the Zhengshin engineers present let out an exclamation.
The suction-type mining ship is not only large, its underwater structure is quite complex. The entire power device is composed of more than 20 parts such as conveyor belts, rollers, drainage pipes, air pressure valves, and reflectors.
The complete drawing looks like a large ship, with two submarines towed side by side, pulling two "shovels" with propellers at the bottom of the water.
The entire workmanship looks quite shocking just from the drawings.
"As you can see, the efficiency of this method of operation is the highest among the most advanced manganese nodule mining methods in the world. However, this method of operation also faces huge assembly difficulties. Compared with conventional The bottom of the water assembly is different, it needs to be assembled in the water or even in the deep sea area, and once the equipment is damaged, it is also a particularly difficult problem to avoid repairs. ”
Looking at Xing Dongliang’s helpless look, all the engineers at Zhengxin smiled knowingly.
Maozi!
How can the design be humanized?
“But the main problem currently lies in our two offshore operating platforms.”
Xing Dongliang played the slideshow to the next page.
"Hydraulic lift mining requires at least two fixed offshore platforms for preliminary separation and processing of raw manganese nodules. As we all know, the so-called fixed offshore platforms are fixed in position throughout their service life. There are three types of platforms: pile type, rope type and gravity type. Because the East Pacific is too deep and has strong winds and waves, we currently use the rope type offshore platform. ”
"This kind of platform is also called a mooring tower platform. It is made by placing a prefabricated steel tower body on the seabed foundation block and anchoring and tightening it with steel cables around it. Its characteristic is that it is suitable for use in large water depths. The sea area. However, the biggest problem now is... our prefabricated steel tower cannot be placed on the seabed due to pressure and current problems. "
With a look of helplessness, Xing Dongliang released the pictures taken in the underwater working area.
Seeing the scene above, quite a few Zhengxin engineers exclaimed.
