The majestic Blue Whale finally stood on the dock of Fuhai Group and became the iconic symbol of Fuhai Group.
The completed closing of the Blue Whale has fully launched the installation and debugging of various equipment. Hundreds of engineers shuttled through the complex passages and rooms of the Blue Whale, recording every piece of data rigorously and meticulously, comparing the specifications on the drawings, and testing
Do these data reach the ideal range?
Feng Chenyi was very busy these days. When he was free, he leaned on the railing of the platform and looked down from the deck. Standing at a height of tens of meters, he had a panoramic view of the surrounding scenery, and
Seagulls pass by from time to time and fly towards the sea in front of them.
At this time, Feng Chen saw more than ten cars of different sizes driving quickly towards the dock where the Blue Whale was docked. He was a little puzzled. He hadn't heard that anyone was coming to visit today!
The convoy soon stopped in front of the Blue Whale. A middle-aged man with gray hair got out of the car in front. Feng Chen recognized him immediately. This was not the construction commander of the Blue Whale, but the president of Fuhai Group.
Engineer Zhang Yujie!
After Zhang Yujie got out of the car, he pointed at the sea around him and said something. Feng Chenyi was too far away and didn't hear it. The staff around him nodded incessantly.
Subsequently, pickup trucks from behind the motorcade arrived one after another and began to carry various equipment from above. When Feng Chen saw these equipment, he immediately understood why Zhang Yujie came here.
The Blue Whale now has the spectacular appearance of a semi-submersible drilling platform, especially its distinctive twin-rig design, which is unforgettable to anyone who sees it.
However, at this time, there is another important piece of equipment that has not been installed in place on the Blue Whale. This is also one of the most dangerous and difficult tasks for the Blue Whale besides the construction and closing.
When the Blue Whale leaves the slipway and sails into the boundless sea, it is a small island that can move and an extremely stable ship.
To achieve this, the Blue Whale must have a powerful power system, especially when it is conducting drilling operations in the rough South China Sea, it needs to ensure the safety of the slender drill pipe drilled into the seabed thousands of meters deep.
Even though these drill pipes are made of super strong materials, the Blue Whale floats on the sea. Once a violent typhoon occurs and encounters strong currents, the Blue Whale must not drift with the tide, but firmly anchor itself like a mainstay.
Fix it in place, otherwise the drill pipe will be broken instantly, causing huge losses and disastrous consequences.
In the past, semi-submersible drilling platforms were generally fixed by throwing ultra-high-strength anchor chains into the sea and using anchor chains hundreds of meters long to stabilize their position.
These anchor chains are made of ultra-high-strength steel. A drilling platform has multiple anchor chains, some even as many as ten, all to maintain the stability of the platform.
However, the anchor chain also has its own shortcomings, such as the length of the anchor chain, strength issues, retracting and retracting time, and the inability to cope with rapid wind direction, changes in ocean currents, etc.
The most critical thing is that the Blue Whale has a huge volume of more than 40,000 tons. Coupled with its huge scale, if it wants to use an anchor chain to control it, it will require at least several kilometers of anchor chain to control it.
Regarding this situation, Zhang Yujie once made an analogy. If the Blue Whale was located in the Forbidden City, the anchor chain could even cover the entire third ring road, or even a larger area. So the economic cost is really too high.
As the most advanced seventh-generation semi-submersible drilling platform, Blue Whale not only possesses various extraordinary abilities, but also has a powerful ability, that is, it does not use anchor chains, but uses the world's most advanced DP3 power
GPS.
The Blue Whale is equipped with eight 360-degree full-turn propellers at the bottom of the platform. It can collect the rotation speed and direction of the propellers, as well as various environmental parameters such as wind, waves, ocean currents on the sea surface, etc., and summarize them into a total
The control room, through precise computer calculations and analysis, controls the speed and direction of the propeller in real time, thereby ensuring that the Blue Whale remains as immobile as Mount Tai no matter what the circumstances, achieving the effect of precise balanced positioning without
Go with the flow.
Today, the purpose of Zhang Yujie's visit is to supervise the installation of the entire thruster.
The equipment transported from the pickup truck were all diving equipment used for underwater work. At the end of the convoy were several flatbed transport trucks common in the factory area. Some equipment was firmly fixed on the vehicle with wooden frames. It didn’t take much thinking.
When it is possible, these pieces of equipment are valuable 360-degree full rotation propellers.
These devices, which are all driven by electricity, have extremely powerful power, allowing the Blue Whale, a 40,000-ton behemoth, to move as steadily as a rock and as cunningly as a rabbit in the vast ocean.
In the past, the installation of propellers for this kind of semi-submersible drilling platform had to be done in the deep sea. The installation fee alone cost more than 10 million. This time Fuhai Group decided to install it at the dock. In this way, it can save at least nearly 90% of the cost.
cost.
Although Feng Chenyi was not involved in this work, he had heard from colleagues talking about the difficulty of this task.
If you want the Blue Whale, which weighs more than 40,000 tons when empty, to move forward bravely in the sea, the propeller is naturally not small. The size of the propeller alone is taller than an adult.
Zhang Yujie held the coded information of the eight thrusters in his hand, and then watched the engineers get into the thrusters to confirm one by one whether the thrusters were consistent with the installation plan in his hand.
These thrusters are installed under the two huge pontoons at the bottom of the Blue Whale. The determined positions are also different. In addition, the thrusters are all controlled in real time by computers. Each thruster has its own unique code.
There must be no deviation from the code name, otherwise it will cause the lowest level of devastating errors.
The installation engineer first carefully checked whether there were any problems with the appearance of the removed propeller to avoid damage during transportation. After everything was intact, two people entered the interior of the propeller and compared the code with the nameplate above. After two rounds of
After verification by different personnel, the installation location of today's first thruster can be finally determined.
Standing behind Zhang Yujie is diver Feng Tianxi. As a diver with more than ten years of diving experience, this is the first time he has undertaken such an arduous task. Although he has undertaken countless propeller cleaning, installation and maintenance tasks before, what he is facing is
This is indeed the first time I have used these huge 360-degree full rotation propellers.
When installing underwater, there is no direct observation between the seawater and the Blue Whale's buoy, but higher requirements are put forward for the accuracy of the installation. The two parties can only communicate through the communication system, so that the installation work can be done
, the difficulty has increased a lot.
This is the primary problem that Fuhai Group engineers must solve.
