C3167 A Craftsman of a Great Country

And for a ship transporting liquefied natural gas, the challenge is the same. The liquefied natural gas needed to be maintained at -162 degrees.

Such a low temperature was not something that could be achieved by a chiller. He had to rely on his outstanding welding technology to produce special materials. Weld became a huge storage container, and this welding was the most difficult of all techniques.

"In the '50s, the West conquered the manufacturing process of liquefied gas boats. However, so far, the world could manufacture such ships. As for us, we will be ranked among the top ships in the world in terms of shipbuilding. " Speaking of which, Zhang had a proud smile on his face.

He had been in Shipyard all his life, and had almost the same experience as Makarov. He had started off as an ordinary welder, and had slowly risen to this point. At the same time, he had also witnessed the power of shipbuilding in the country.

In the field of military ships, we can already build aircraft carriers. In the field of civil shipbuilding, we also have to build our own liquefied natural gas cargo ships!

If we don't build such ships, then the shipbuilding industry in Han Country will never be the strongest. It's impossible to be dazzling on the world shipbuilding stage, and this is also part of the country's strategic goal. Show the spirit of our country.

As an industrial country, we must be able to build this kind of cargo ship. Furthermore, this is also related to the country's energy strategy. Han Country was rapidly becoming an energy exporter, and it needed to import a large amount of oil. It also needed to import a sufficient amount of natural gas. As the environmental protection mission became more and more important, there would be more demand for natural gas. All of these required a large number of natural gas cargo ships to transport. If they couldn't manufacture it, then they could only buy it from overseas at a high price.

Faced with this challenge, they had put in a lot of effort.

"There are two main types of liquefied gas storage, the independent tank type and the Shroud type. The former places cylindrical, cylindrical, spherical, and other tanks inside the ship. You can see the tanks protruding out of the ship, while the latter uses a double shell structure. The inner shell is the vessel of the container, similar to the oil mill. The latter had a high capacity utilization rate and a light weight structure, but at the same time, it was also more difficult. So, we decided to start from the former and build a few more ships. After mastering the technology, we will build the latter."

Zhang introduced the ships as he led the group to the construction site.

At this time, the shiny special boards had already appeared in everyone's field of vision. At the same time, there was also soothing music playing at the construction site.

"While the hull is being built, we have also started welding these most important gas tanks. They are spherical. Right now, the ones welded here are these tanks that contain liquefied natural gas."

After saying that, Zhang smiled and said, "We all call this work embroidery on steel plates."

Qin Guan nodded and said, "Let's just watch from the side. Don't let it affect the work of the workers."

Qin Guan knew the difficulty of welding.

Yin Wa Steel was a special steel that adapted to this kind of super low temperature. This kind of steel was relatively thin. The requirements for welding were very stringent. To what extent was it stringent? No sweat could drip onto it, no handprints could be left behind. No additional pressure could be applied to it, not even a pen.

What if this happened?

Then it would be scrapped. The steel plate that was welding had to be replaced. Moreover, the surrounding steel plates that were connected to it had to be replaced.

At this time, the workers were working under such a request. The bright exterior of the steel was bright and beautiful, just like a mirror. The welders were calmly listening to the music. The steady welding was like fishing for copper coins in a rolling oil pan. It was like chopping meat stuffing on Zhenguan Xi's back, their work... It was very important.

Not only were sweat drops not allowed to fall down, even a little welding was done. This was a natural gas cargo ship. During the voyage, once a welding point had a void welding and leakage, the whole ship would be destroyed.

Balls that stored natural gas were powerful bombs. Moreover, this was not the most serious. If it was during the unloading at the port... If there was a leakage and the gas boat was ignited, the entire port would be blown up.

Therefore, it was quite a test for the workers. Not only did they have excellent technology, but they also had a stable mentality.

"We have to check the workers' bodies every day. Their heartbeats don't match. We can't go up. If their blood pressure is high, we can't go up. If they're not in a good mood, they can't go either. " Zhang said from the side, "In the past, we paid attention to light injuries and not going down the line of fire. Now, in this kind of welding, there's no need to say light injuries. Even if it's just a slight nose flame, it won't do it. "

Qin Guan nodded. "Yes. These craftsmen were all the most precious wealth. We will soon have a special program for craftsmen from a large country. Reporters will come to interview us. You must also be prepared to select a few excellent craftsmen to be interviewed. This is a way to show the strength of our country, and we can't let it go. "

After Qin Guan said that, Zhang immediately understood what was going on. "Don't worry. The Han Country is the best in the world. It is different from the R Country."

When Zhang said this, he even patted his own chest. "Back then, when we mounted the liquefied natural gas cargo ship, there were still some questions from the leaders. I said that there was a problem and I will be held accountable. We built ships for our entire life, but we didn't board the aircraft carrier. There must be something challenging on board, right?"

This kind of super cold storage on the sea was the most challenging cargo ship in the world. Of course, they had to accept this mission to show their superior their elegance. It was absolutely not inferior to the Shipyard in the north.

Hearing such determination, Qin Guan smiled and nodded. "Don't worry, although the aircraft carrier won't be your turn, he said. However... You still have a chance at using the navy's amphibious assault ship. The Shipyard in the north has a lot of missions and can't be rushed. There will definitely be an order for you. When the time comes, you can't let it go. "

When Qin Guan said this, he was already very serious.

The navy was about to have a three-aircraft carrier formation, and the Han Navy would become the second strongest navy in the world. The construction of the Amphibian assault ship was about to begin.

According to the plan, this kind of attack warship had to enter the water as soon as possible to serve in the army, so there was a chance to build it here.2

Zhang was clearly asking for battle just now. He was still brooding over the fact that there was no mission to build the aircraft carrier. Now, just a ten thousand tonnes destroyer was not enough to satisfy him at all.

However, Qin Guan had already promised to give him the construction mission of the Amphibian attack ship. This was forty thousand tonnes. In many countries, it was already enough to play the role of an aircraft carrier.
