The rapid development of the shipping industry of the Daheng Empire is accompanied by the rapid development of the country's industry and commerce after the unification of the empire, the internal inland transportation network of its own country, the strong demand for maritime transportation on the east coast, and the transportation demand on the east and west coasts is also strong.

Subsequently, the international trade of the Daheng Empire is also rising year by year, especially after seven years of Qiansheng, the total international trade of the Daheng Empire is increasing year by year, and now the total annual international trade is billions of Hengyuan, and its total international trade is second only to the Krull Kingdom, becoming the second in the world, the development of international trade, and once again promoted the rapid development of the imperial shipbuilding industry.

When the shipbuilding industry developed rapidly, it also directly promoted the progress of technology, and in the past, the shipbuilding industry of the Daheng Empire was very reluctant to even build a 10,000-ton cargo ship.

This is not to say that it can't be built, but the technology is too scummy, the construction cost is relatively high, and the performance is not very good, not to mention the need for more manpower to operate, and the coal consumption of the steam unit is also relatively large, so that the transportation cost of the built ship is much more expensive than similar foreign products.

However, with the progress of technology, especially the vigorous development of the navy of the Daheng Empire, it has directly promoted the progress of domestic ship steam engine technology, although up to now, the ship steam engine technology of the Daheng Empire, especially the core multi-expansion steam engine, its overall level is still not as good as that of the Krull Kingdom, but it is also a world-class level, and it will not be too bad.

In addition, the Daheng Empire caught up relatively quickly in the field of boilers, which also made up for some shortcomings in the steam engine.

Therefore, the overall performance of the ordinary merchant ships produced by the Daheng Empire is already quite good, and with the continuous increase in cargo volume in recent years, and the international trade of the Daheng Empire is getting bigger and bigger, there are more and more ocean-going large-tonnage freighters.

Today's Daheng Empire has to launch a large number of large merchant ships of tens of thousands of tons almost every year, including bulk carriers, special cargo ships, and larger high-speed passenger ships.

In March of the 14th year of Qiansheng, the Daheng Empire Endless Sea Shipping Company, the Duke of Meng's cruise ship officially made its maiden voyage, which caused a certain sensation at that time.

Because it is a super-large luxury cruise ship with a displacement of 23,000 tons, it is the first giant ship of the Daheng Empire, looking at the world, it is also the third largest luxury cruise ship in the world, second only to the two flagships of the Judir Shipping Company of the Kingdom of Krull, well, the tonnage of the flagship is even more exaggerated, and its largest Judir is directly named after the company, with a full load displacement of more than 30,000 tons, known as the first giant ship of the Blue Star, which is much more than those battleships.

In today's international shipping market, the high-end luxury cruise market has always been fiercely competitive, but in the early years, this competition was not as big as ever.

Because Daheng people do not immigrate, and they do not like to go abroad, the people who travel between Daheng and other countries are mostly businessmen, and there are few ordinary people.

However, with the economic revitalization of the Great Heng Empire, the volume of international trade is getting bigger and bigger, which requires more and more people to travel to and from all over the world.

After all, in the past, there were only hundreds of millions of Hengyuan in international trade volume a year, and now there are billions of international trade volumes.

The first in the Daheng Empire, and now the largest endless sea shipping company, launched a 10,000-ton ocean liner in the 10th year of Qiansheng, and then launched a 15,000-ton luxury passenger ship in the 12th year of Qiansheng, and launched its new generation flagship Duke Meng in the 14th year of Qiansheng last year.

And carry out the international route from the Great Heng Empire to the Kingdom of Krull and then to the Kingdom of Walya.

The Duke of Meng's cruise ship, to a certain extent, can also reflect the development of the shipbuilding industry of the Daheng Empire, you must know that this thing is more than 18,000 tons, not to mention, and it runs faster than a warship.

The speed of a battleship of the same tonnage is basically still at twenty knots, and even if it is a high-speed battlecruiser pursued by the Great Heng Empire, its speed is only twenty-three or four knots.

But the maximum speed of Duke Meng was able to reach twenty-six knots!

The use of the most advanced steam engine of the Daheng Empire, the injection of oil to support the combustion of coal-fired boilers, and the frenzied accumulation of a bunch of steam units, so that the speed of the ship exceeds that of the main warships of various countries, and it is also the fastest large passenger ship on the Blue Star.

Last year, when the inaugural voyage of the international voyage was carried out, the average speed remained above twenty knots during the inaugural voyage from the Daheng Empire to the Krull Kingdom!

With the speed of the ship and the ability to maintain a high average speed, almost no warship will be able to outrun it!

Such a power system represents the excellent shipbuilding ability of the Great Heng Empire.

At the same time, the huge and bulky coal-fired boiler and a large amount of coal-fired take up too much space and weight, and they want to build a pure oil-fired boiler warship, which will definitely be faster and have stronger endurance, which can keep the cruise ship at a high speed for a longer time, and then increase the average speed.

Now the oil-fired boiler technology of the Daheng Empire is relatively mature, after all, the Daheng Empire is not short of oil, and has begun to study pure fuel technology early, and it has been tested on many light warships, and it has also been tested on many civilian ships.

The military is already planning to massively adopt oil-fired boiler technology on capital ships.

The luxury cruise ships of Endless Sea Shipping Company have always kept up with the most advanced technology, so they also want to engage in a luxury cruise ship with pure oil-fired boilers.

At this time, they didn't know about the steam turbine secretly researched by the Daheng Empire, and if the Endless Sea Shipping Company knew about the huge potential of the steam turbine, it was estimated that they would want to build a luxury cruise ship with a steam turbine and an oil-fired boiler.

However, compared with the semi-public oil-fired boiler technology, the steam turbine technology of the Daheng Empire is a top-secret technology, and the technical research is directly funded by the navy, by state-owned or royal-funded enterprises, or simply the official research institute participates in the research, and the entire research process is in top secret, and the outside world does not know that there is such a thing.

Lin Ziran knew very well that the huge power increase brought by the steam turbine was greatly improved, so the relevant research was kept secret throughout the whole process, and he could hide it for as long as he could.

When the steam turbine is built, and then combined with oil-fired boilers and other supporting related technologies, the main battleships of the Daheng Empire can run more than 25 knots, the battle cruisers can run more than 289 knots, and the cruisers must be 30 knots or higher.

Such a high speed is enough for the Great Heng Imperial Navy to lay a huge tactical advantage!
