As soon as this sound came out, Shi Si and Yang Xueting pinched a little bit of soft flesh under Yuan Bing's ribs and twisted it hard. The guy's face immediately turned the color of pig liver, and he almost screamed.
I don’t know if Zheng Xiurong heard Yuan Bing’s impolite compliments. She still smiled and said to Ling Hao in fluent Mandarin: “We have received a notice from Mr. Li Liang that you need the things and people. Everything is ready. From now on, Mr. Ling will fully direct this rescue work. Chief of Staff Park and I will assist you and provide you with all conveniences."
Ling Hao nodded and said: "Okay, time is urgent, I won't be polite to you. 26 hours have passed since 192 hours, let someone find a larger countdown electronic clock to hang in a conspicuous place, like this This will allow all those involved in the rescue to reduce prevarication and delay and improve work efficiency. The large equipment on the cargo plane must be transported to the helipad of this warship as soon as possible. We must install and debug the equipment as soon as possible. We cannot take off or land here for the time being. The plane has arrived. Also, we need to install a crane arm at the stern of the ship. Please allow us to drill holes on the deck to install bolts." Ling Hao was not polite and started giving orders directly.
The warship immediately became busy. Ling Hao's equipment was transported onto the ship in batches. Yuan Bing and Zuo Pengfei led a group of crew members to start installing the hydraulic mechanical boom, while others began to check their diving equipment.
Shi Si was probably the busiest one. He pulled out a data cable from the command cabin of the warship, then connected his laptop to the satellite, and then connected the LCD screens one by one, and then connected the detection equipment one by one. Throwing down the water, she then dragged a few equipment boxes to use as tables, placed her laptop and a row of monitors, picked up an apple-flavored lollipop, and clicked on the keyboard. After tapping, not only was it connected to the satellite network, but it was also connected to the intranet of the Navy of country C.
In an instant, various information appeared on the display screens, including sea conditions, weather conditions, underwater current conditions, tide conditions, water temperature conditions, sea water salinity, etc. All the information related to this rescue mission was only available on the screen. Within half an hour, they were all captured by Shi Si. This cute-looking little girl was indeed a super geek that many hacker organizations around the world wanted to poach.
Jiang Mingyu led several military doctors from Country C and a group of nurses to a meeting in the helicopter hangar. He informed them of the emergency methods for treating decompression sickness and took out the medicines to teach them how to use them.
At this time, several "big things" were also transported by tugboats. The hydraulic boom had just been installed and they were all lifted onto the deck one by one. After peeling off the tightly wrapped canvas, the true colors of these devices were revealed.
Two white metal tanks with a length of 6 meters and a diameter of more than 2 meters are equipped with various instruments and pipelines. There are more than a dozen seats arranged inside the tanks. This is the decompression chamber, whether it is for divers before saturation diving or after submariners emerge from the water. , all have to use this device to reduce pressure. The transport plane has limited space and can only bring two in. The forty officers and soldiers plus the living cabin can also be used to decompress, which is enough.
In addition to the two decompression chambers, there is also a huge oval underwater living chamber, which is about the same size as the two decompression chambers combined. It looks like a crab without legs, and the sides are really painted with red paint. There are four words on it - "Stone Crab Number".
The most eye-catching thing is a small yellow scientific research submarine. The bow is a round thick quartz glass pressure-resistant cover, and there are three mechanical arms retracted under the hull. There are also four words on the side of the small submarine. ——"Pippi Shrimp".
These things not only opened the eyes of the sailors of Country C, but also made Zheng Xiurong very curious. She walked over to Shi Si who had finished his work and asked, "What is this lot of equipment used for? It looks like it's for people."
Shi Si glanced at her and asked, "Sister agent, do you know what 'saturation diving' is?"
Zheng Xiurong shook his head in embarrassment, and Shi Si chuckled. For the sake of 2.2 million euros, he patiently explained to her: "The water pressure in deep water is very high. When people go down to the deep sea, under the high pressure, they have to breathe The gas in the lungs will dissolve into the blood. If it rises quickly at this time, the person's blood will instantly produce many bubbles like opening a bottle of Coke. This situation is the so-called 'decompression sickness'. Therefore, it can only be Decompressing bit by bit when surfacing is very time-consuming, leaving very little time to actually work on the seabed. To deal with this kind of rescue work, the 'saturation diving' method must be used. Before entering the water, the diver first The decompression chamber is pressurized to the operating depth pressure, and the decompression chamber, living chamber and deep-diving submarine are also connected together and pressurized at the same time. After pressurization, the diver enters the living chamber, and the boom will carry the deep-diving submarine The living cabin is lowered into the water. Our living cabin called "Stone Crab" is the most advanced in the world. It can maneuver underwater. After finding the wrecked submarine, it can then sink to the bottom of the sea. Divers take the "Pippi Shrimp" 'The deep submersible finally approached the wrecked submarine, demolished it, and rescued the crew members inside and brought them back to the living cabin. The divers can also return to the living cabin to rest after working for a long time, eliminating the trouble of floating up and decompressing."
Zheng Xiurong was stunned for a while. These things seemed a bit science fiction to her and she couldn't understand them at all. However, she had an understanding of the professionalism of Ling Hao's team, and she also had a good understanding of this rescue. I feel relieved a lot.
An electronic countdown clock was hung up. The scarlet Arabic numerals on it showed 162 hours, 21 minutes and 19 seconds, and the numbers were still decreasing by the second.
The "Pippi Shrimp", "Stone Crab" and decompression chambers have been connected and sealed, and the bulky deep-diving suits have also been loaded into the "Stone Crab". Everything is ready. Ling Hao and Tian Yong, Yang Xueting and Zuo Pengfei got into the decompression chamber and began 45 hours of pressurization.
Zheng Xiurong became curious again and asked Shi Sidao with a smile: "Why does it take so long to pressurize? And why do their diving suits seem more complicated than space suits? And who are the two large bottles outside the decompression chamber? What gas is it?”
Shi Si looked at Zheng Xiurong, who was blinking his big eyes and looking like a novice who was seeking knowledge. He pulled the lollipop out of his mouth with a click, and said patiently: "There are too few people in our industry, so professional knowledge is It’s not popular. It’s not surprising that you don’t know it. In fact, it’s not profound. I’ll explain it to you and you’ll understand. Pressurization of the human body must be done bit by bit, not too fast, otherwise it will be very dangerous. To It takes about 45 hours to pressurize to the same pressure as the depth of 375 meters underwater, no one is exception. There are two torpedo launch tubes at the stern of the wrecked submarine. According to the standard configuration, in order to facilitate the access of divers on the submarine, they should There is a decompression chamber behind each torpedo tube. When the contact time comes later, you can notify the wrecked submarine and let the crew go to pressurize. Try to squeeze in as many people as possible. They may only have two chances to pressurize. No matter how long it takes, I'm afraid the weak physical condition of the survivors will not be able to bear it anymore. The air you and I breathe is a combination of nitrogen and oxygen, but what Ling Hao and the others are breathing now is 'helium oxygen', the same two you see. The gas in the cylinder. Because nitrogen has a strong anesthetic effect on nerves under high pressure, pure oxygen can easily cause cerebral oxygen poisoning under high pressure, and helium, an inert gas, has relatively mild underwater paralysis. But even so , the impact on the human body will still be obvious. There is a 'Martell's law'. When breathing helium and oxygen, every 10 meters of diving is equivalent to drinking a cup of 'Martell', and 375 meters is almost a barrel. , so divers are easily fatigued at this depth and have to sleep for 12 hours a day. The four of them will be divided into two groups and work in turns. The speed of sound propagation in helium and oxygen is three times that in nitrogen and oxygen. So their voices in the communicator will sound very shrill. Don't laugh when you hear this. Let's talk about the bloated diving suit weighing 76 kilograms. Its scientific name is "hot water suit". The deep water is extremely cold, and this "heat" The principle of the water suit is similar to that of floor heating. It is full of hot water pipes to prevent the diver from freezing. If a person rescues the submarine, he will start to decompress in the living chamber, and the decompression process will be very long including the divers. , it will take about 20 days, which does not guarantee that the submariners will not develop mild symptoms of decompression sickness. In other words, this rescue mission will take at least a month, so you must be mentally prepared for this."
Zheng Xiurong was a little stunned. Only now did she realize how complicated deep sea diving is. This is only less than 400 meters, and in the deep sea of thousands of meters, wouldn't it be even more difficult for humans to set foot there? ? No wonder humans know more about the moon than the deep sea.
There were 117 hours, 6 minutes and 43 seconds left in the countdown, and it was dusk again. Ling Hao and the four finally completed the pressurization and entered the living cabin "Stone Crab" from the decompression chamber. After the hatch was sealed, Yuan Bing led the sailors to quickly dismantle the bolt connection between the decompression cabin and the living cabin. The boom was extended to connect the "Stone Crab" and "Pippi Shrimp" that were still connected. The "Pipi Shrimp" was hoisted and lowered to the sea little by little. Yuan Bing stood on the top of the "Pippi Shrimp". When the living cabin was floating on the sea, he untied the cable and then swayed with the crane arm. Pose, like a trapeze artist, returned to the deck. Unfortunately, not only was there no applause, but almost no one looked at him. Everyone's attention was focused on the bubbling "Stone Crab" which was slowly sinking.
Yuan Bing curled his lips and continued to weld his "waterproof cabin" with a look of helplessness.
Shi Si was currently wearing plush pajamas with "Snoopy" patterns all over, and a pale hydrating mask on his face. He smiled into the communicator and said: "Boss, are you surprised or surprised? Now? There must be a large number of 'hammerhead sharks' surrounding your windows, right? According to underwater radar detection, the number is no less than 500. You have to be careful when you reach the bottom of the sea. They can move easily at that depth, and you They all look delicious, and I don’t rule out that they will want to take a bite.”
"Shut your crow mouth!" Ling Hao's shrill roar came from the communicator.
"Uh... don't be so fierce. You have now reached a depth of 200 meters and are about to enter the 'Yellow Sea Coastal Current'. There will be some bumps. Please fasten your seat belts and hold on to the armrests. The grid on the right side of the seat is You have prepared your vomit bags. I wish you all a happy journey! Ho ho ho." Shi Si held up the crow's feet at the corners of his eyes with his hands and smiled so hard that he deserved to be beaten.
Before Ling Hao could curse, the "Stone Crab" seemed to rush into a torrent, and it suddenly tilted. If Ling Hao hadn't grabbed the handrail, he would probably have fallen down. Zuo Pengfei grabbed the joystick and quickly corrected the course, so that the "Stone Crab" would not be swept away from its target on the seabed.
At 350 meters, they descended to the "seafloor constant temperature line", which is the limit of the impact of sunlight on seawater temperature. Below that is the area beyond the reach of the sun's warmth. This is also the dividing line between seawater with different salinities. The seawater is clearly stratified up and down, as distinct as oil and water. It looks very magical. Those who are lucky enough to see this spectacle immersed in the world are not alone. There will be more than 500.
Finally, after fifteen minutes of diving, they finally approached the bottom of the sea. It has to be said that although this girl Shi Si is naughty, her positioning is indeed accurate. The "Stone Crab" is only a few dozen meters away from the wrecked submarine.
"Ask Shi Si if Yuan Bing's water-proof cabin is ready. Put it down when it's ready. Pengfei and I will go first on the first shift. There will be another shift every six hours." With that, the two began to work hard. Wearing a "deep diving hot water suit".
Not long after, two "half-drawn cylinders" welded by heavy steel plates were dropped to the bottom of the sea by hanging steel cables. Ling Hao and Zuo Pengfei got into the "Pippi Shrimp" submersible and broke away from the "Stone Crab". The propellers rolled up a vortex and headed towards the two suspended steel cylinders, and the underwater submarine rescue work officially began.
