By the way, he told me a little more about safety, emphasizing that it doesn't matter if you make less money, don't take your life on the line: a large part of the salaries of divers, crew members, and advanced detection intelligence personnel are linked to the value of the salvage.

It's a good thing when there is power, the ship below is sunk during the war, the name of the cargo ship is unknown, the type of cargo is unknown, God knows what is inside.

The wartime materials are strange, ordinary explosives are quite trivial, and it is normal to have a lot of highly toxic materials in them. There is good news, judging from the previous investigation, there are a lot of aquatic creatures below, at least they have not been poisoned, but the next salvage will inevitably have to be underwater blasting, and God knows what will be blown up.

Not to mention anything else, blow up a few tons of potassium cyanide and sodium cyanide commonly used in heat treatment in the steel industry, it will be really lively - not to mention entering from the mouth, even the slightest contact with the solution containing this kind of cyanide in the skin can easily kill people!

As for environmental pollution...

It's not your own home, just care about it, the sea still has a strong ability to purify.

……

Forty-five minutes after Bruno gave the instructions to the divers to get out of the water, several divers surfaced and returned to the deck of the cargo ship.

There is no need to decompress, after such a long period of strict segmented floating, the originally compressed air in the body has been slowly released, and the person will not be put into it because the compressed gas in the body expands too quickly to be released.

Diver's disease can be avoided, but the physical exertion of the guys is not small, the underwater operation at a depth of 50 meters is already tiring, and carrying those lead ingots weighing more than 30 kilograms underwater is a proper heavy physical work!

The previous leader of the launch was a 37-8-year-old veteran naval engineering diver named Chris Wilson, who was giving a detailed report on the underwater discovery.

"The size of the wreck is a bit different from the previous preliminary exploration, it is not that big, the length is only about 130 meters, and the displacement is at most about 7,000 tons.

In the middle, due to the effects of the torpedo explosion, the hull was bent ...

Chris made an introduction, and also marked the printout photos taken by the unmanned submersible before, "... There is not much sediment inside the two large holes, but only the tin ingots near the breaches can be easily made, and a large area of cutting must be carried out... This kind of, oh, this tantalum rod should have been packed in a wooden box, and there are many similar decayed and damaged wooden boxes on the inside of the blast, and the specific number is difficult to estimate..."

This will be in the dining room that is used as a temporary conference room, and as soon as Chris Wilson finished introducing the ship, a senior crew member on the "Big Shark" speculated: "Could it be the Type 1A wartime standard ship of the little devils, which feels very consistent with the shape and tonnage standards of the wreck..."

The guys on the ship are basically from the Chinese and US Navy, even if they only managed their own one-third of an acre of land when they were soldiers, they still know some things about the Japanese Navy in World War II, especially for some guys from the US Navy.

In the Pacific War, the Americans were the main force fighting the Japanese army, not to mention the present, and they will talk about it for many years in the future.

Zhang Nan doesn't know much about these, he only knows about the little devil's cargo ships, passenger ships or something, and they all like to call this pill and that pill, and the whole one sells strong pills, and basically doesn't understand anything else.

After listening to the guessing crew, they understood what a wartime standard ship was: it was a cargo ship built by the little devils according to uniform specifications during the Taiping War.

In a big battle, what will every naval power do, the most famous is the famous "free wheel" of the Americans, a big guy with a weight of about 7,000 tons, and built 2,751 ships in one go!

Because the wartime standard ships of the little devils are aimed at mass production, in order to shorten the construction period and cost, they can save on shipbuilding materials and marine equipment, so these ships are poorly equipped, have low speed, poor reliability, and low service life, but they are cheap and can be produced quickly in large quantities.

Throughout the Pacific War, Japan had four batches of wartime standard ship production programs of about 30 types, and by the end of the war a total of more than 1,000 ships had been produced.

Of course, the vast majority of them are not as large as the American "free wheels", and there are not many small ones of several hundred tons.

As for the production of the first batch of battle-marked ships, it actually began a few months before the attack on Pearl Harbor on December 7, 1941, so the quality of the construction of this batch of ships was okay. With a length of 128 meters and a full load displacement of about 6,800 tons, the Type 1A cargo ship is the largest tonnage cargo ship in the batch except for oil tankers.

Because of the use of a steam engine with a small power, the speed was only 12 knots, and it was mainly used for transportation between the mainland of the little devil and the occupied areas of China and the south, and a total of 9 ships were built.

According to the weight and loading coefficient of the general bulk carrier, the weight of the cargo in the wreck should be about 4,500 tons - the little devil should be fully loaded, for them, every voyage of the southern route is important and precious, and the cargo ship will not be loaded with half of the cargo.

It takes the same risk to run a trip with half of the goods fully loaded, and everyone will be full and set off.

With this calculation, Zhang Nan smiled and said to his fellow men: "I hope that there will be at least pure tin level goods in it, and if it is loaded with thousands of tons of rubber, it will be useless." ”

All agreed!

In World War II, natural rubber was a very important strategic material, but the shelf life of that thing was generally only a few months to two or three years, let alone soaking in seawater - even if it was stored in an iron drum, it would be almost 50 years later, and even the best rubber would become slag.

In fact, fresh natural rubber is just over $1,000 a tonne, but it is not as valuable as the common non-ferrous metals produced in Southeast Asia.

Staying on the "Big Shark" for dinner, Zhang Nan likes to be with his friends, and by the way, he asks through the intercom how the salvage boat sent out is - so far, his yacht and the Ming Dynasty soup spoon salvaged by the salvage boat can add up to 30,000 or 40,000!

The food on the big ship is good, although it is not as fine as on its own yacht, but it is better in terms of quantity and momentum!

There are a lot of American guys who pull rice into their mouths with a pair of chopsticks, and there are also many Chinese guys who take fresh bread as a staple food.

Zhang Nan is very satisfied with this, at least there is no contradiction on the surface, these people have not cooperated for a day or two, and once a guy with racist tendencies jumps out, all the fucking fuck will fuck me out!

No matter where it comes from, it doesn't matter if it comes from!

"When we are human, they are still monkeys!" Such classic words can only be said by Zhang Nan himself in private, and whoever else says will get out.

Boss, you always have to be a little privileged in private.

Oh, Brother Guan and brother-in-law are exceptions.

Besides, this "privately" does not include their own home, otherwise the women will be mad.

I thought about it a lot, and as soon as I thought of the woman at home, the woman's call came.

It's Nicole.

"Honey, did you have a good time with your two little girlfriends?"
