The d90 platform was designed and developed by foreign companies through repeated efforts. Its shortcomings and hidden dangers have been discovered in various practices and have been rigorously modified. This is simply a very mature design plan.
The first task Feng Chenyi faced was to dismantle this mature plan and make it comply with the unusual technical specifications of the Blue Whale.
This is like someone giving you a piece of high-end ready-made clothing. It is of high quality and style, but does not fit your figure. You need to modify it yourself. The modified clothing needs to maintain the same or even higher quality.
This not only seems to be a very difficult thing, but to do it is also a difficult problem comparable to the difficulty of the Shu Road.
The key is that as long as the technical load demand increases a little, the corresponding intensity of the basic improvement will increase exponentially. The superficial data alone is enough to give Feng Chen a headache. Even so, there are still more mountains and seas of data emerging.
When I came out, I almost pressed down the gourd and picked up the scoop. There were all kinds of changed data everywhere.
The members of the design team can only keep calculating and move towards the goal bit by bit, like a small boat in the rough waves, hoping to successfully reach the other side of victory.
"Dr. Feng, according to this data requirement, the platform may not be able to bear so many devices!" The designer responsible for calculating the carrying capacity suddenly found Feng Chenyi.
Feng Chen was stunned. This kind of basic mistake should never happen!
"Are you sure there are no errors in your calculations?" Although he also knew that this kind of thing was almost impossible.
"I've calculated it three times, and the results are the same!" the designer said helplessly.
Feng Chenyi looked at the data marked in red, indicating that the original platform strength could not withstand such high data pressure and had to be strengthened again.
"What is our basic platform data now?" Feng Chenyi asked with a frown.
"The total length of the platform is 115.0m, the width is 78.0m, the height of the pipe frame deck is 42.4m, the pontoon is 110.0m long, 16.0m wide, and 11.6m high. The column is 16.0m long, 16.0m wide, and 22.0m high. The upper platform is 74.0m long.
The width is 74.0m, the pipe frame deck is 77.0m long and 78.0m wide, the working draft is 23.6m, the displacement is 52,932 tons, the working environment temperature is -20℃~40℃, and the sea water temperature is 0℃~35℃!”
These data have long been memorized in the minds of designers, and they speak out immediately.
"The data on the basic platform is insufficient. We can increase the width of the platform, increase the strength of the pontoons accordingly, and increase the length slightly! See if the data is consistent!"
Since the intensity is unbearable, then strengthen and expand the scale of the platform. This is the most direct and effective method, but it requires a trade-off between economy and effect.
The designer was stunned for a moment. He didn't seem to expect that Feng Chenyi would use such a seemingly stupid and crude way to solve the problem!
Feng Chen turned around and looked at the somewhat dull designer, "What? Doesn't this method work?"
"Okay, of course!" The designer smiled bitterly. He thought the doctor had a special trick.
The designer immediately used the pressure data to calculate the applicable platform dimensions, and soon a behemoth with a length of 117 meters, a width of more than 90 meters, and a height of nearly 120 meters was born on the drawings.
If the d90 platform occupies the size of a standard football field, the behemoth in front of us needs four additional standard basketball courts.
"Oh my God!" When the loaded data appeared in front of Feng Chenyi, he sighed instantly.
On paper, the Blue Whale has become the largest semi-submersible drilling platform in the world. According to the design requirements, it has an operating water depth of more than 3,500 meters and a drilling depth of 15,000 meters. It has the ability to
Global deep sea operations capabilities.
This is the real blue whale, a behemoth that can traverse the four seas, an extraordinary super project.
When Feng Chenyi put the huge data in front of everyone, the team members were dumbfounded, and then everyone was excited. They could get the title of No. 1 in the world, and they wanted to participate in it. This was a big deal anyway.
kind of glory.
"Based on this data, we will immediately come up with a design plan for the basic platform!" Feng Chen made the final decision one by one.
Everyone immediately started the design work in a hurry, and carried out a comprehensive and detailed design of the basic platform of the Blue Whale from all aspects.
The deep-sea semi-submersible drilling platform is known as the crown jewel in the field of offshore engineering equipment. This is not without reason.
Since the day it was born, offshore drilling platforms have been continuously upgraded with the development of science and technology.
Initially, a fixed drilling platform was used, which is a device that fixes the jacket on the seabed so that it does not move above the sea surface. A deck is laid on the platform to place drilling equipment. The legs that support the fixed platform are driven directly into the seabed.
The stability of the drilling platform is very good, but because the platform cannot move, the cost of drilling is very high.
In order to solve this problem, many mobile drilling platforms were born, such as the bottom-mounted drilling platform, which uses sinking pads to pressurize and sit on the seabed. After drilling is completed, the ballast can be discharged, floated, and moved to another well location.
, but is subject to operating water depth and seabed geological conditions.
There is also a self-elevating drilling platform that has strong adaptability to the seabed. The platform can move up and down along the pile legs. It has strong adaptability to water depth and good working stability.
However, the leg length of a jack-up drilling platform is always limited, and there is nothing you can do if you want to drill in deep sea.
The semi-submersible drilling platform came into being. It consists of a working deck and a lower hull, connected by support columns. During operation, most of the floating body can be sunk below the sea level to minimize the impact of waves.
The basic platform of the Blue Whale is semi-submersible. It has two huge caissons like torpedoes and four super-large columns, which can support a body weighing tens of thousands of tons. Above the columns is a huge platform for
Various equipment required to build a drilling platform, as well as living areas for staff.
The South China Sea has always been a place where tropical storms gather, and an astonishing number of storms rage every year. If the Blue Whale wants to occupy a place here, it must have the ability to fight the storms head-on, and its huge body is naturally indispensable.
The design of the basic platform is in full swing, and they need to take all imaginable issues into consideration, from safety to economy, from science to humanity, everything needs to be done down to the smallest detail.
One by one, the ideas turned into drawings, piled up around him, and finally turned into a huge blue whale skeleton.
After working around the clock and forgetting to eat and sleep, Feng Chen's team came up with a design plan for the basic platform, a full two weeks ahead of schedule, which left Clover's designers speechless.
