Chapter 325 325 Shipbuilding
Datang Group has been improving its shipbuilding technology recently. The most extensive manufacturing technology innovation they are experimenting with now is a new technology called welding.

A steel battleship is spliced ​​together by steel, and there are only two ways to splice steel, one is welding and the other is riveting.

Riveting is a relatively primitive and very bulky connection method, but it also has its own advantages. The advantage is that it is old enough.A sufficiently old technology means that it is mature and reliable.

The Burnas-class battleship that Tang Mo first built actually used a lot of riveting structures, but then he began to experiment with welded structures on the Wolf-class battleship.

Although welding is a very advanced manufacturing technology, the biggest problem with new technologies is that it takes time to train new workers, and it also takes time to digest.

There is no way, even the Datang Group can only train its welding workers step by step, so that they can master this skill as soon as possible.

At the same time, it takes time to prepare the gas required for welding, so the Datang Group has only recently begun to use brand-new welding technology to build civilian ships.

With the new technology, the so-called civilian ships, or simply steel steam-powered transport ships, began to be mass-produced at a faster rate.

In general, this new warship uses the freewheel design of the World War II era, but it has been simplified in some special equipment to make it more suitable for current technological manufacturing capabilities.

After all, even in the Datang Group, the technical level of workers was still around 1910, far from the level of 1940 when the technology was mature.

It is not impossible to barely manufacture things around 1940, but it requires the concentration of a large number of high-tech talents, which cannot be mass-produced, and the gains outweigh the losses.

Of course, since the drawings were directly copied, most of the technical parameters also use freewheels, which basically look the same.

This kind of ship needs practicality, rapid mass production, standardization and homogeneity, and does not need any performance or aesthetic feeling at all.

The displacement of the empty ship is 7000 tons, the total length of the ship is 135 meters, the width is 17.3 meters, and the draft is about 8.5 meters.

This size is already bigger than a battleship. Tang Mo's previously designed battleships did not have this width at all, nor did they have this level of displacement.

In order to obtain as much supplies as possible anywhere, the propulsion system adopts the most traditional and currently most used coal power.

The whole ship is equipped with three steam engines, which together drive a propeller, with a total output of 2000 horsepower.

Even so, the speed of this kind of ship is actually still a weakness. Its speed is actually only 20 kilometers per hour!
That's right, this speed is about 10 knots. Compared with the wolf-class cruiser Tang Mo made, its speed is really too slow.

Moreover, it only has very few wires, and even the telegraph is an optional product. Most of the cabins in the entire hull do not have electric lighting.

This large transport ship has an endurance of up to 2 kilometers, and can sail to almost any seaport in the endless sea with a single supply. This is also a very practical performance, which can make shipping more efficient and faster.

Unlike World War II, when anti-aircraft guns and deck guns had to be installed on the hull in order to deal with German submarines and aircraft, this kind of ship does not need to be equipped with any weapons at all.

Therefore, weapons are also optional-one 75mm naval gun can be installed on each side of the ship, which is more than enough to deal with pirates and even the navies of other countries.

Because the load has been reduced in other places and the artillery has been eliminated, the limit load of this transport ship has been increased to 1 tons, and it can carry about 6000 tons of cargo.

Almost the same as Liberty Ship, this ship can load 250 new trucks produced by Datang Group or 400 T-type cars at one time, and the cargo of these cars weighs about 2500-3000 tons.

在装运了这些车辆之后，它还可以见缝插针的运输另外的1000吨弹药，轻武器500吨：含轻G1重机枪，5000支K3步枪、迫击炮200门、75毫米口径野战榴弹炮80门左右。

Then, it can also transport 500-1000 tons of food and supplies at the same time-this is almost all the weapons and equipment that two standard infantry regiments of Datang Group's security forces need to equip.

Of course, if one item of cargo is loaded separately, this kind of ship can also load a lot. If it only transports T-type cars, it can load 2840 vehicles at a time. If it transports bullets at a time, it can easily transport 2.3 million standard rounds. K3 rifle bullets.

These ships are very simple, but they are huge. They are bigger than all previous sea ships, and the materials that can be transported at one time are also scary.

Therefore, in order to allow these freighters to go to sea with a full load, Datang Group will increase the production capacity of all products so as to be able to support an increasingly large maritime capacity.

The capacity of such a ship is comparable to that of an entire fleet of sailing ships in the past. This is a subversion, a complete subversion of the way of maritime transportation in the past!
This kind of ship uses a set of 2000-horsepower reciprocating steam engines as power. Although the speed cannot be so fast that it can greatly surpass the sailing ship, it is also much faster than the past sailing ship.

Although these Ice Crystal City-level designs are outdated, they are very reliable. They use a lot of mature technology, and they can be reduced in unnecessary places.

Anyway, the crew of this era are also half-slaves who are used to hard times. They are used to living in the dark cabin. A dozen people can have a porthole, which can already be described as happiness.

They don't need too sophisticated food, nor do they need refrigeration equipment, their food will not be eaten by pigs in the 21st century, and their salary is lower than the basic salary of a newly graduated insurance salesman.

So these people will not clamor for electric lights and other messy benefits. It is already a kind of happiness for them to have a dormitory and sleep on a stable iron bed.

Compared with preparing them for a better working environment, giving them a salary increase is what makes them more ecstatic.Working on this ship, at least they don't have to worry about the invasion of pirates. This extra security has already made them grateful to Dade.

After all, the speed of most pirate sailing ships in the world is only about 12 kilometers per hour, and it is basically impossible to catch up with ships at 20 kilometers per hour.

Even if they can catch up to these Datang Group's version of Liberty Ship, a huge ship with a displacement of more than 7000 tons, they can easily smash into the sailboat blocking the way, and then walk away without any psychological burden.

Only the cargo hold, captain's cabin and wheelhouse of this kind of ship are illuminated, and gas lamps are used in other places for temporary emergency.

The welded keel ensures the reliability of the hull, and some less important parts are replaced by wood in large quantities, which greatly reduces the cost of this kind of ship.

In order to facilitate manufacturing and maintenance, the accommodation area, bridge, and engine of the ship are all concentrated in the midship, and a long channel is used to connect the engine shaft and the propeller.

In order to reduce costs, the newly developed engine is not equipped for this kind of freighter. It still uses a slightly bulky and old steam engine, which allows it to be replenished in most ports. At the same time, mature technology also has a high probability of eliminating mechanical Fault.

Of course, the Datang Group will not admit that the use of steam engines is to clear the inventory, revitalize the steam engine manufacturing factory in North Ridge, so that the investment in North Ridge can be more or less profitable for upgrading.

Datang Group will not admit that the production capacity of the latest engine is seriously insufficient, and the failure rate is also high, so it cannot replace the mature steam engine for the time being.

In order to adapt to the not-so-mature shipbuilding method, Tang Mo changed and optimized the design to make the ship faster and cheaper to build.

Partitions that could not be used were all canceled, and there was almost no anti-sinking design. The only purpose of this was to increase the construction speed and save precious steel resources.

The construction time of the first Liberty Ship of Datang Group was 91 days, which is still a shipbuilding time record that a large number of skilled craftsmen worked hard to get out.

But then, the construction speed of this kind of ship was increased to 68 days to build one!This speed is simply appalling, because even in the ancient sailing age, the time required to build a warship greatly exceeded this record.

At that time, the wood needed for a warship needed to be dried for several years, and it often took more than a year to build a warship.

This is why there is a saying that the army lasted ten years and the navy lasted a hundred years. The century-old navy here not only includes the cultivation and accumulation of talents, but also includes the navy's shipbuilding speed.

In fact, today, when the Datang Group is about to completely end the war of 11 countries, there are already five Liberty ships sailing on the sea.And next, this magical merchant ship will be launched at a rate of one every nine days.

Soon, Datang Group will be able to build a fleet of ships with a speed of more than 20 kilometers per hour that can transport tens of thousands of tons of products at a time, allowing them to travel on the endless sea that used to represent isolation and prohibition.

For the entire world, this speed of shipbuilding is undoubtedly a miracle. It has turned the Endless Sea from a natural barrier into a traffic hub, and has become a hot throat.

And when these transport ships brought a large amount of supplies to Refeng Port, the fragile logistics of the lobby group's fleet across the sea off the Tarun Kingdom were completely guaranteed.

Although there is no professional sea supply ship, it is still possible to use small boats to barely transport some fruits and vegetables and replenish some coal.

In fact, the artillery shells carried by a battleship are really too abundant to attack a port, and there is no need to replenish them.

Moreover, Bernard received the order, and it seems that there will be no need for large-scale shelling in the future.
