Songjiang Prefecture is located at the southern end of the exit of the Yangtze River, with three counties: Huating, Qingpu and Shanghai. There is also a Jinshanwei. Qin Yu came down here on a warship and came here, and he was quite moved.

Thinking of the prosperity of the demon city in my previous life, as well as the small fishing villages, small counties, and large areas of mudflat wastelands, it was just one in the sky and one underground.

Qin Yu's first stop was Shanghai County. He knew that Shanghai in his previous life was very large in area, covering almost part of Songjiang Prefecture and Suzhou Prefecture, but it not only refers to the small Shanghai County now.

This time, when I came to Songjiang Prefecture, in addition to finding a good port as a shipbuilding base, I also wanted to build it into a port city for foreign trade, so as to facilitate the establishment of a Maritime Bureau and collect tariffs in a unified manner.

Similarly, he planned to upgrade Songjiang Prefecture to an independent prefecture, abolish the Jinshanwei under his jurisdiction, and be directly managed by the center, as a transit station for goods in the entire Yangtze River Basin.

Due to the continuous erosion of the Yangtze River, the area of ​​Songjiang Prefecture extends to the sea almost every moment. After several days of turning, Qin Yu found a place suitable for building a port and a place suitable for building warships.

Although Qin Yu had been to Shanghai in his previous life, he could not tell the difference between the southeast, south, west and north now, except for the difference between the south, south, and north, and there was no reference at all.

But that doesn't matter, because this port is very suitable for building a wharf, with a water depth of basically around seven or eight meters. Even the largest treasure ship of this era will not be stranded when fully loaded.

The key is that the port is more than ten miles long and extends inland at a glance, making it convenient for building a large number of warehouse workshops and urban buildings.

This time, Qin Yu brought hundreds of officials from the Ministry of Works and thousands of old shipbuilders, all of whom were plundered in the Jiangnan area recently. After hearing the huge project described by Qin Yu, everyone was shocked and dropped their chins.

Not to mention the shipyard, the ten-mile-long pier can accommodate thousands of sea boats in and out at the same time, which is daunting. The huge warehouse group behind the pier and countless workshops are even more unimaginable. Once built, how spectacular and lively it will be?

Qin Yu’s idea was that in the future, flat-bottomed merchant ships would deliver goods from provinces along the Yangtze River to the place where they would be shipped by sea to all over the world, so this dock would be divided into three.

A three or four-mile-long section close to the north will be used as a river wharf for river boats to dock, ten miles in the middle, as a seaport, and a port close to Hangzhou Bay to the south, as well as a large wasteland, as a shipbuilding base.

As for the navy's port, Qin Yu planned to choose Ningbo. After all, the place where the warships are parked cannot be too close to the trade terminal. Even the shipbuilding base must be completely isolated.

After choosing the place, Qin Yu and hundreds of workers' officials and thousands of craftsmen planned on the spot for more than half a month before roughly dividing the huge project.

The two docks and shipbuilding base will be built at the same time, and will be completed in ten phases. It is expected to use millions of workers and will be completed within ten years.

After the planning of the Jianghe Wharf and the sea wharf, Qin Yu no longer took care of it, but gave it to the officials of the Ministry of Works to take charge. He himself devoted himself to the detailed construction plan of the shipbuilding base.

The trading port can be built slowly, but the shipbuilding base must be grasped quickly. The scale of this shipbuilding base is far from comparable to that of Hanyang.

In the future, not only warships will be produced, but also civilian sea ships will be produced. Qin Yu’s preliminary plan is to excavate five large dry docks that can accommodate about 2,000 to 3,000 tons of sea ships.

Then there are ten medium-sized dry docks, which can accommodate about 1,000 to 2,000 tons of sea ships, thirty small dry docks of about 500 to 1,000 tons, and finally one hundred open-air ship platforms.

The lifespan of wooden warships is extremely short, but if they can be maintained once a year, remove the attachments on the bottom of the ship and repaint them, they can greatly extend the service life. It is not impossible to use for 10 or 20 years.

Of course, it is not that easy to build a dry dock. If it weren't for cement, Qin Yu wouldn't dare to imagine it. With rubber, the gates can be completely sealed. The only troublesome thing is the drainage problem.

But Qin Yu believes that his steam engine will be able to be solved in a few years, and this problem will be solved by then.

Of course, if he waited for the dry dock to build before building a warship, he would probably have to wait until the year of the monkey and horses to go, so he had to build a warship on the ship platform for a long time. In short, he was not in a hurry to build a dry dock, but he had to build it, and the effect would be huge in the future.

One of the reasons why Zheng He died of voyage to the West when he was exhausted was that the cost was too high, and the treasure ship could not be maintained and it was scrapped in a few years.

The method of shipbuilding is also modular assembly, first designing the warship model, then decomposing it into tens of thousands of parts, and processing it in the subsequent woodworking workshop, and finally being spliced ​​and assembled.

The advantage of this is that once a standard is formed, it will not only be built quickly, but also save costs greatly. You can also choose suitable wood according to different parts of the hull.

In order to ensure accuracy, Qin Yu not only made a unified ruler with the carpenters, but also invented the caliper. No, it should be said that it was a copy.

Because of this thing, Wang Mang from the Western Han Dynasty seemed to have made it out.

The construction of woodworking workshops, supporting workshops, ship platforms, and excavation of docks are simple for the time being, and only a lot of manpower is required, but the design of warships and component decomposition is an extremely complex and systematic project.

It is absolutely impossible to be illiterate. For the time being, some people who know the text and literacy can only be eliminated to join, but this is not a long-term solution, so a special Ship Design Academy and Naval Academy have to be established.

The treasure ship has been lost. Instead of trying hard to copy it, it is better to redesign it in combination with the concept of Chinese and Western shipbuilding.

For this reason, Qin Yu had already asked Guo Biao to go to Macau to dig some Portuguese who knew how to build ships. Although there were not many, only a few, it was enough.

Seeing dozens of old craftsmen and a few red-haired ghosts, they were quarreling every day, and they wanted to rush their arms and fight, Qin Yu was also as big as a fight.

"Okay, don't make a noise. I set a standard. You will design it according to this standard. First of all, we need to build four warships in total, two small ones, two large ones, and the maximum speed of the small ones cannot be less than ten knots, the displacement is between two hundred and five hundred tons, the minimum speed of the large ones cannot be less than five knots, and the displacement is about one thousand tons to two thousand tons."

"Oh, my goodness!"

"Dear Emperor, I am forgiving me, your standards are really desperate. A wooden boat with a displacement of 1,000 tons cannot be built at all. As far as I know, the largest wooden boat in the Netherlands now has a displacement of about 300 tons."

Several red-haired ghosts first exclaimed, and then spoke in poor Chinese, shaking their heads like wave drums, all of whom felt that His Majesty the Emperor was too whimsical.

Dozens of old carpenters can now distinguish the concept of one ton. After hearing the words of several red-haired ghosts, they were immediately unhappy and began to refute.

"Hmph, what's so strange about the Netherlands you mentioned is just a mere country that can't build a sea ship of more than 100,000 dan?"

"My ancestors were craftsmen at Longjiang Shipyard. The largest treasure ship built by Longjiang Shipyard back then was about 43 zhang and five feet long, about 7 zhang and two feet wide, and the main mast was eighteen feet long. As for the displacement, you can calculate it yourself."

"Impossible, absolutely impossible, I will never believe it unless you build that treasure ship now for me to measure it myself."

Several red-haired ghosts also retorted with a flushed face, thinking that these Chinese people were crazy and they didn't believe that there could be such a big ship in the world.
Chapter completed!
