Chapter 428 Salvage Bailang Wan

The long black rubber catheter continuously delivers oxygen to the deep-sea diving suit, and the catheter is pulled into the sea little by little. It is obvious that the divers are constantly swimming and expanding the search area.

In addition to delivering oxygen, this long rubber catheter also has a telephone line embedded in the catheter, allowing divers to communicate directly with people on the crane boat underwater.Hei Qi led several sailors under him to monitor the situation of the catheter.

According to Hei Qi, it is a bad idea to use a diver wearing a deep-sea diving suit to find the sunken ship. The deep-sea diving suit is already very bulky, and it is also limited by the distance of the oxygen tube and the speed of movement. I want to rely on the deep-sea diving suit to find it. It is very difficult to sink a ship. First, it depends on luck, and second, it takes a long time.

There are two underwater work boats on the Hailaoyue, which are actually two remote-controlled submarines equipped with robotic arms. Generally, when Hei Qi and others search for sunken ships, they put these two submarines into the sea .

The submarine moves very fast, and there are two mechanical arms that can perform some simple operations, and the detection range is much larger than that of divers wearing deep-sea diving suits. However, because of the magnetic field, these two diving The boat is now useless at all, and it can only be the next best thing.

After about an hour, the diver wearing a deep-sea diving suit surfaced for the first time. While taking off his diving suit, he kept panting, and at the same time told everyone what he found after going into the sea.

The diver brought back good news and bad news. The good news is that there is a deep-sea mountain range directly below the crane ship. The cross-sectional area of ​​this mountain range is very large, and the height of the mountain range is also very high.

The distance from the sea level to the bottom of the sea, that is, to the top of the mountain range, is not very deep. The shallowest place is 80 meters, and the deepest place is only more than 100 meters, which is completely within the range that can be salvaged.

The bad news is that the sea water in this sea area is very turbid, and there are a lot of floating objects in the sea water. These floating objects make the visibility in the sea water low, and it is very difficult to search for the location of the sunken ship.

After changing another diver, No.2 diver continued to search according to the search area described by No.1 diver.Even wearing deep-sea diving suits, divers cannot stay underwater for too long at one time, which will seriously damage the body's functions.

So Hei Qi asked several divers under him to search for the location of Bailang Wan in turn. Each search lasted about an hour to an hour and a half. In this way, several divers could take turns to rest each other. People rested, and the deep-sea diving suit did not rest. .

No one expected that the magnetic field here would actually interfere with electronic equipment. Usually, when Hei Qi and the others searched for sunken ships underwater, they used remote-controlled submarines, so they only prepared one set of this deep-sea diving suit, which was prepared to Used in the event that both submarines are damaged, it can be said to be the backup plan of the backup plan.

The possibility of damage to both submarines is almost zero, so this deep-sea diving suit is usually useless at all, and there is no need to prepare an extra set, but now it has seen defects.

Even if Liu Cong was very anxious, he couldn't use his strength at all, and there was no way to help speed up the search.There is only one set of diving suits, and it is necessary to constantly go up and down to change divers. The time wasted on changing divers accounts for almost one-third of the search time, and the efficiency is really poor.

Hei Qi smiled and said nothing, Liu Cong and the landlubbers are so ridiculous in his eyes, this time the speed of locating the sunken ship is already very fast, according to his estimation, if Liu Cong and Chen Ziyang's locating method is effective If not, the sunken ship will be found nearby in less than three days.

This efficiency is already very scary, that is, people like Liu Cong seldom touch the ocean and the work of salvaging sunken ships, so they are so anxious, and they don't even know that the location of sunken ships is usually calculated on a yearly basis. Units.

Chen Ziyang thought of a way to speed up finding the sinking place of the Bailang pill, and that was to use that coffin nail.As long as the coffin nail is brought underwater, the coffin nail will be closer to the mechanism coffin, maybe it will be attracted by the magnetic field and directly indicate the direction.

But after thinking about it for a while, he gave up on the idea.Although this method is theoretically feasible, there is a problem, that is, it is not known whether the glass cover can withstand the water pressure of the deep sea.

If you can't bear it, the glass cover will be crushed by the water pressure, then the coffin nails will affect people's mind, and the gains will outweigh the losses.So after much deliberation, Chen Ziyang felt that it was better not to bring up this idea, but to take it slow, now that sophisticated electronic instruments can no longer be used, it is better to be safe.

After searching the nearby sea area every day, Hei Qi would drop the anchor in another place, and then search the nearby sea area again. In this way, three days passed, and it was not until the fourth day that the divers who went into the sea found a sunken ship. .

However, due to the relatively far distance, and the fact that the sunken ship may be covered with marine life and a thick layer of dust, and the oxygen tube has been extended to the maximum length, the diver only saw one in the distance. It looks like the prow of a ship. I don't know if it is a rock or it is really the sunken Bailang Maru.

Liu Cong was overjoyed by this discovery, so Hei Qiqi hurriedly recruited the diver back, drove the Hailaoyue towards the sunken ship for a certain distance, re-anchored, and let the diver return to the sea to see what happened .

"It is confirmed to be a shipwreck! The steel structure, from the outline, conforms to the characteristics of a large merchant ship during World War II." The diver's excited voice came from the phone.After a while, the diver's voice came again on the phone, and this time, he was so excited that he was about to shout out.

"This ship should be Bailang Maru. Although the place where the ship's name is written on the bow is occupied by marine life, it is impossible to see clearly, but I found a pistol in the nearby sand, which was used by Japanese military officers during World War II. The bastard box!"

After hearing these words, everyone on the boat couldn't help cheering.Liu Cong jumped up and down on the deck excitedly, like a big rabbit.

The diver kept describing the situation of the ship, and provided important information to Hei Qi and others on the deck so that they could analyze the salvage method.

Normally, this kind of work only needs to be watched through the submarine's camera, but now because the submarine is unavailable, the video camera and camera are also unavailable, so this step has been changed to dictation.

Fortunately, the divers under Hei Qi are very experienced, and Hei Qi has been in the sea and under the sea for so many years, he has an inseparable guess about the situation of the sunken ship, and he has a very good relationship with the divers. tacit agreement.

One of them was talking and the other was drawing. Soon, the terrain around the sunken ship and the structure of the sunken ship were presented on the paper, and the rest was to find a way to salvage it.

In the original plan, Liu Cong planned to let Heiqi send people to search the cabin directly, find the iron book, and bring it to them, and then Liu Cong and others returned to Shanghai.

As for how much Hei Qi can salvage from the sunken ship, it depends on his ability. The more things he salvages and the higher the value of the salvaged items, the less Liu Cong will pay him.

But the situation is different now. Without submarines that can operate in deep seas, it is very difficult to do this.The deep-sea diving suit is limited by the length of the oxygen conduit and the terrain, so it is not realistic for divers wearing deep-sea diving suits to salvage, and it is easy to encounter danger.The only way to search the hold now is to salvage the ship.

Fortunately, according to the description of the divers, the overall structure of the sunken ship does not seem to have been damaged, so it will be easier to salvage it.

There are many ways to salvage the sunken ship, which are affected by various factors such as the structure of the sunken ship, the construction materials of the sunken ship, the angle and inclination of the sunken ship, the depth of the sunken ship and the terrain environment near the sunken ship.

Bailangwan is a cargo ship with a steel structure. According to divers' observations, from the outside, there is no obvious damage to the surface of Bailangwan, and the overall structure is relatively complete, so it will be easier to salvage.

There are usually two salvage methods for this sunken ship made of steel and with a relatively complete structure.If the weight of the cargo in the wreck is not heavy, the underwater workers will usually attach some small airbags to the stronger parts of the wreck.

After these airbags are opened, the chemical substances in the airbags will react quickly, so that the airbags will be filled with gas quickly, so as to increase the buoyancy of the sunken ship, coupled with the pulling force of the crane arm on the lifting ship, the sunken ship can be pulled directly towards the water.

The second method is to discharge the seawater in the cabin, and let the buoyancy naturally drag the sunken ship up slowly.The specific method of operation is to put some very large air bags into the largest compartments of the sunken ship, and then inject air into these air bags.

After the air compressor compresses the air, it is directly injected into the air bag, so that the air bag in the cabin will gradually become larger, and the seawater in the cabin will be squeezed out. When the seawater in the cabin is almost discharged, the ship itself will sink. The weight of the boat is reduced, and it will rise to the sea surface under the effect of buoyancy.

The first method of placing airbags on sunken ships is very simple to operate, and does not require operators to enter the interior of the cabin, it only needs to be completed outside.

However, judging from the data, Bailangwan carried a lot of gold and silver, dozens of boxes of antiques, and some other metal industrial materials when it set off. The weight of the hull should be relatively heavy.

Even if the grains loaded in the Bailang Wan have been broken down after so many years, the weight of the remaining goods is still very heavy.The number of airbags brought by Hei Qi and the others is not many, and they may not be able to lift such a heavy boat.

The second method is safer, but it also has a disadvantage, that is, it needs to send someone to install the airbag in the cabin of Bailangwan.This is almost impossible to do.

There is a very evil mechanism coffin inside Bailang pill. Liu Cong has already told Hei Qi and his crew about this, which is why the divers have never entered Bailang pill because they are afraid of this coffin.

Even if the coffin is harmless, there is only one set of deep-sea diving suits, and it is almost impossible for one person to install such a large airbag in the cabin.And divers don't necessarily have the guts to do it, either.

After studying for a long time, Hei Qi decided to adopt a three-pronged compromise method.

The first step is to mount some small airbags on the surface of Bailangwan, and the second step is to fix the hook protruding from the boom to the hull of Bailangwan.

The third part is a modified method to discharge the seawater in the captain, that is, instead of using a large airbag, the air duct is directly inserted into the cabin or cargo hold, and air is pumped into it to discharge part of the seawater.

With the small airbags to increase buoyancy, the weight of the sunken ship can be reduced with the help of air, and with the help of the powerful boom, it is only a matter of time before Bailang Wan floats to the surface.As soon as this proposal was proposed, Liu Cong immediately agreed.

It seems that this method is more troublesome and requires three parts to work at the same time, but after thinking about it, this solution is very safe.

First of all, the diver does not need to enter the interior of the sunken ship. He only needs to mount air bags and steel cables on the surface, and extend the air duct into the cabin.

The second advantage is that the workload of this solution is not large. Even if there is only one deep-sea diving suit, all the work can be completed within two days.

After the plan was formulated, Hei Qi started to arrange it immediately.Now Hei Qi has a smile on his face all the time, he is really very happy, his happiness can no longer be expressed in words.

As long as the Bailang Maru is salvaged, among other things, the 20 tons of gold in the cabin alone is enough for him to eat, drink and have fun in his next life.

The business of this trip was really very profitable. It took less than ten days to locate a sunken ship. This was much better than drifting at sea for a year or two without finding anything.

Under the arrangement of Hei Qi, several divers lined up their shifts, and one by one they went underwater with small airbags, and tied these small airbags to a relatively strong place on the sunken ship.

The installation of the steel cables on the lifting arm was also relatively smooth. The four steel cables were respectively fixed on the left and right sides of the bow and stern of the sunken ship. The force points of these four steel cables were relatively evenly distributed. , so as not to pull the hull in two.

All that's left is to insert a few air ducts into the hold for air injection.A diver in a deep-sea diving suit came to the side of the wreck with a long catheter, which he then inserted into what appeared to be a hole in a cargo hold breach.

"Moo..." A strange sound suddenly rang in the diver's ears, and his face instantly turned pale.
