"When will you go?"

In the office, I heard that Li Fanyu was going to the East Pacific in person, An Ning looked reluctant. Recently, An Ning's mood has changed a lot. Sometimes she loses her temper with Li Fanyu, but she often sticks to him like a child.

Li Fanyu quietly touched her hair, "This time I went, I just check the underwater construction situation, mainly to collect data for the first time in the robotic arm to perform on-site operation in a harsh environment. If there is no problem, Liu Qing and the others can do these tasks, and I will come back in a few days."

An Ning nodded, and then he said with confidence, "Then you come back as soon as possible."

Seeing her suddenly sticking to herself, Li Fanyu smiled badly, "If you say you can't live without me, I can't think about it even if I haven't seen you for a day, then I can't go!"

"Bah!" An Ning rolled his eyes, "Smile, you don't bother to care about you if you like to leave!"

Li Fanyu shook his head helplessly, not understanding what this woman really wants.

After receiving another call from Liu Qing, Li Fanyu and An Ning hugged each other, after a few words of advice, they walked downstairs and took a bus to the Zhengxin Special Port next to the industrial base.

Liu Qing and others had already loaded the ship, so they were waiting for him to get on the ship and leave.

In the past ten days, Zhengxin completed the fastest modification of the work arms of the 15 Jiaolongs, and took another five days to test the sea outside the city. However, due to the environment, Liu Qing and others only conducted simulated tests of 5,000 meters below the sea and actual environmental tests of 2,500 meters below the sea. Everyone was still very cautious about the working state under the water of 5,000 meters.

That is why Li Fanyu, the main designer and a technical backbone such as Liu Qing, need to follow up and bring a large number of spare parts and maintenance facilities to ensure that problems with the robotic arm work underwater can be solved at any time.

The whole world knows that these new technologies of Zhengxin are particularly harsh.

However, all users of Zhengxin Power are particularly satisfied with the technical support and service in the three phases of pre-sales and middle-end sales!

Almost all Zhengxin Power products, whether they are large ship engines, general engineering platforms in 1911, or voles diggers, after all the products are sold and delivered, Zhengxin will take out the drill team to follow up for a period of time. No matter which country the user is or the size of the user's order.

On the one hand, the matching situation between collection and use and other supporting facilities, on the other hand, Zhengxin’s team will also provide complete technical support to ensure that there are no problems after the product is put into use.

It is precisely because of this powerful service and technical support that Zhengxin Power's current products are the best among all products of the same level.

This time, the order was reached with the Ocean Exploration Bureau, and this is even more so.

After intense consultations, the Marine Exploration Bureau agreed to pay 1.5 billion in advance and ensure that if the manganese nodule mining area in the Eastern Pacific Ocean is successfully mined, it will provide Zhengxin with a supply period of ten years at a cost price.

In fact, this agreement would definitely not be passed if it was in normal times, but in order to get Zhengxin to work hard, the above was also pinched and recognized after research.

After all, the mining period is only less than half a year left. If the construction period is at the end of the project, it is not the time to sacrifice this little profit!

Carrying Li Fanyu and others and more than a dozen special cargo ships of Jiaolong, they rushed to the eastern Pacific Ocean with the maximum speed.

The giant ship was working overtime at sea. In the activity room of the cabin, Zhengxin's technicians were also enthusiastically accepting project decomposition and technical key points of CNOOC and the Marine Exploration Bureau.

"In the subsea mining project, we need to follow the influence of the seabed minerals by seawater and sedimentary biological resources. We originally planned to use low efficiency, but it is also the easiest way to mine deep-sea manganese nodule minerals, which is a single-boat single-bucket type. However, the mortgage submitted to the International Ocean Association was not approved. According to the requirements of the International Ocean Resources Association and the Ocean Association, subsea mining must take into account the impact of the mining process on marine organisms and renewable resources. Therefore, we can only be forced to adopt the current mainstream international CLB-II deep-sea mining plan."

"This mining plan is a hydraulic lifting plan, which requires us to have one or even multiple subsea mining equipment, corresponding number of ore lifting equipment, large towed ships, and at least two offshore operation platforms!"

"We have invested 12 billion from Russia to customize three sets of the most advanced Ikimiri-style super-large suction mining ships designed by the Moscow Mining Institute and produced by Uriyang Shipyard. We have also provided a set of water conservancy lifting equipment developed by scientific research units under our bureau. This is our drawing, please read it."

When they saw the large ship that was much worse than the Jingwei on the slide, the Zhengxin engineers present exclaimed.

The suction mining ship is not only large, its underwater structure is quite complex. The entire work-making device consists of more than 20 parts, including conveyor belts, drums, drain pipes, compressed air valves, reflector plates, etc.

The complete drawing looks like a big ship, dragging two submarines side by side underneath, pulling two "shovels" with thrusters at the bottom of the water.

The entire workmanship looks quite shocking just from the drawings.

"Everyone has seen that the efficiency of this operation method is the highest among the most advanced manganese nodule mining methods in the world. But in the same way, this operation method also faces huge assembly difficulties. Unlike conventional water assembly under the seabed, it needs to be assembled in water or even deep-sea areas. And once the equipment is damaged, it is also a particularly difficult problem to avoid maintenance."

Looking at Xing Dongliang's helpless look, all the engineers of Zhengxin smiled knowingly.

It’s Russian!

Where can I talk about the designs in a human way?

"But the main problem at present is still our two offshore operation platforms."

Xing Dongliang played the slideshow to the next page.

"Hydraulic lift mining requires at least two fixed offshore platforms to be used for preliminary separation and treatment of manganese nodule ore. As we all know, the so-called fixed offshore platform is the position that remains unchanged throughout the service life. Its forms include pile type, rope type and gravity type. Because the depth of the Eastern Pacific Ocean is too large and the wind and waves are relatively large, we are currently using rope type offshore platforms."

"This platform, also known as the cable tower platform, is to place a prefabricated steel tower body on the base block of the seabed and tighten around it with steel cables anchored and tightened. Its characteristic is that it is suitable for sea areas with large water depths. However, the biggest problem now is... due to pressure and current problems in the seabed, our prefabricated steel tower body cannot be placed."

With helplessness on his face, Xing Dongliang released the pictures taken in the work area under the sea.
