On this day, after the design team's regular discussions, each designer returned to their respective workstations and racked their brains to transform the production process.
Yang Zhonghan also returned to his desk. As a newcomer among the four-leaf clovers, he also recommended himself through the hero post and became an enviable member of the four-leaf clovers in the eyes of everyone.
Although he also graduated with a major in shipbuilding and won a big award for his graduation project that year, facing a behemoth like the Blue Whale, he also felt that his knowledge was lacking.
Since being assigned to the drilling rig system design team, he has been constantly looking at the world's top drilling rig design plans, eagerly asking for advice from his colleagues, and wanting to contribute his own strength to this huge project.
The drilling rig is the most important core component of all drilling platforms. The development of land drilling rigs far exceeds that of offshore drilling platforms. There are various reasons, the main one being platform limitations.
At present, land drilling rigs have been able to reach drilling depths of more than 15,000 meters. Even the ultra-high standard of the Blue Whale this time only drilled to a depth of less than 3,500 meters.
Yang Zhonghan put together several sketches of the drilling tower he drew, hoping to choose the best among them and find the best plan.
As he looked at it, a ray of sunlight shone on the drawing, and his eyes were a little dazed. At that moment, a bold idea suddenly burst out of his mind, and he himself was shocked by this idea.
Yang Zhonghan placed the two sketches of the drilling tower side by side and then looked at them carefully, with an excited smile on his face.
"You think, can we do this?" Yang Zhonghan said to his colleagues, and then waved the two sketches.
"Twin-rig structure?"
The designers were immediately stunned by this fresh idea.
This idea was indeed novel enough, but it still needed Zhou Yan's approval. Yang Zhonghan was encouraged by his colleagues to report to Zhou Yan.
"Director Zhou, our team has come up with a special idea, but we just don't know if it can be realized!" Yang Zhonghan knocked on the door of Zhou Yan's office.
"What do you think?" Zhou Yan asked, looking at the young designer in front of him, not dissatisfied at all for disturbing his thoughts.
"It's like this. Our usual drilling platforms use a set of drilling equipment, and the drill pipes are limited in length. Even if our drilling tower is taller, it cannot meet the drilling depth of tens of thousands of meters, so each section of drilling
After the pipe is drilled, you need to use a top drive to lift the drill rig to connect the drill pipe, and then drill. The deeper the drilling, the longer the drill pipe required, and the longer it takes to take over!" Yang Zhonghan said, blushing a little.
Already.
Not to mention being the director of the design department of a marine equipment company, even an ordinary shipyard worker is probably familiar with this work process.
Zhou Yan listened carefully to the other party's explanation without any boredom.
As if feeling Zhou Yan's encouragement, Yang Zhonghan continued: "Can we design a secondary drilling tower system in addition to the main drilling tower? The main drilling tower is responsible for drilling and the secondary drilling tower is responsible for taking over. This can save a lot of money."
time, I just don’t know if this setting is useless!”
After listening to his explanation, Zhou Yan's expression was the same as that of those designers.
This is definitely a stunning innovation!
It is the first time in the world to set up a double drilling tower structure on a semi-submersible drilling platform. Although the cost has increased, as Yang Zhonghan said, it can save a lot of time. With the current design of the Blue Whale
The drilling capacity can save at least 30% of the time.
Since the Blue Whale is used for deep-sea drilling and development, which is far away from the coastline, the higher the efficiency, the deeper the well the equipment it brings can be drilled, which can save a lot of time, which means the higher the efficiency of the platform, the natural benefits are also
The better, and it can also save a lot of money for the final owner.
In Yang Zhonghan's eyes, the director's expression seemed to deny this idea, and he was suddenly discouraged.
He didn't expect that after Zhou Yan was surprised, he immediately slapped the table and said: "What a great idea. This is definitely a creative proposal. You should go back immediately and come up with a plan for this idea in detail!"
Yang Zhonghan was immediately overjoyed. He did not expect that his inadvertent move would be recognized by his master and receive such a high evaluation.
After Yang Zhonghan left, Zhou Yan looked at the model in front of him and immediately combined the two drill towers into one and placed them on top, forming a huge double drill tower structure.
Zhou Yan looked at the double drilling tower structure in front of him and immediately put forward his own opinion, or a more radical idea, that is, the two drilling systems are exactly the same, instead of having a positive and a negative, so that the operation can be greatly improved.
Improve efficiency.
However, another problem arises.
That is such a huge drilling system, and its operating speed also plays a vital role. If you want to speed up the operation of the Blue Whale, you must transform the original operating system to improve work efficiency.
Zhou Yan's mind seemed to be opened immediately. Innovation means breaking out of the original constraints. As long as combustible ice can be mined quickly and effectively, all methods can be tried and all technologies can be put to use.
Zhou Yan immediately conveyed this intention to every designer. Don't be afraid that your ideas will be rejected. As long as the ideas are consistent with scientific principles, they can be used on the Blue Whale.
The design of the twin-tower structure suddenly enlightened many designers. They had always locked their ideas on how to improve the platform, but did not think of completely creating a new way of working or architecture.
Wonderful ideas emerged one after another.
Zhou Yan was not idle either. He stared at the drilling system in front of him. Since he was already preparing to build a dual drilling system, he wanted to further improve work efficiency and could only start with the top drive.
The full name of top drive is top drive drilling device. It can directly rotate the drill pipe from the upper space of the derrick and send it downward along the special guide rail to complete the drill pipe rotation drilling, circulate drilling fluid, connect the column, shackle and reverse drilling, etc.
A variety of drilling operations can significantly improve the capability and efficiency of drilling operations.
Since its research and development began in the 1980s, top drives have become one of the outstanding achievements in the development and update of drilling equipment automation. Almost all offshore drilling platforms will use top drives to improve drilling productivity.
He has handled dozens of drilling platforms. Whether it is a sixth-generation semi-submersible drilling platform with tens of thousands of tons or a jack-up drilling platform with several thousand tons, almost all drilling systems use elevators for their top drives.
The same winch requires workers to operate it accurately, and the running speed is relatively slow.
If the operating speed of the top drive can be increased, it will significantly improve the efficiency of the entire drilling system.
The top-drive winch is driven by electricity, which is advanced enough, but Zhou Yan also wants to make it even more advanced, that is, by using a fully automatic hydraulic device.
This can not only reduce the power consumption of the platform, but also greatly improve work efficiency, and even many original devices can be changed to hydraulic power.
This bold idea is no less than the twin tower structure proposed by Yang Zhonghan.
