October 18, 2021 is known as a "milestone" for Chinese shipbuilding, because on this day the Chinese shipbuilding industry achieved the first complete connection of a large cruise ship, and it took only two years and 12,260 tons of steel to accomplish this feat.
We all know that China's ability to build ships is not inferior to that of developed countries, and even far ahead of other countries with better manufacturing development in many fields.
But why is China slow in the field of cruise shipbuilding?
After two years of running out of 12,260 tons of steel, the large cruise ship named H1508 finally achieved the full shipbuilding.
Building a luxury cruise ship is fraught with difficulty.
The H1508 is a large Chinese-built luxury cruise ship built in Waigaoqiao, Shanghai, with a total length of 323.6 meters, which is a super giant cruise ship and can accommodate up to 5,246 passengers.
And this luxury cruise ship can also be described as difficult to build.
When the H1508 is a perfect ship from the outside, it seems to be symmetrical, but in fact it is extremely complex on the inside.
The internal system engines of a large cruise ship need to be laid out several times to be able to place each part in the right place.
The construction process of a large luxury cruise ship requires the construction and assembly of 25 million parts, and the shape, size and other elements of these parts must be carefully considered.
The slightest mistake in the construction process could have caused the construction of this large luxury cruise ship to fail.
This also leads to a long construction time and complex process for a giant luxury cruise ship, with not only one but also several types of mechanical materials, each of which needs to be produced according to the production plan.
This leads to a construction process that can only be completed by manpower due to complicated processes and unpredictable factors such as weather.
There will be a certain upper limit on the number of cruise ships built every year, and there will be a certain amount of demand, and there will be no oversupply or even no one wants it.
If China wants to develop its shipbuilding industry, it must start from the root cause and develop its own shipbuilding industry and improve all aspects.
At present, China's shipbuilding industry started later than that of developed countries, and its management is extensive, and there is a certain gap between its construction level and that of developed countries.
In addition, shipbuilding equipment is relatively backward compared with other developed countries, lacking high-end equipment, and the skill level of workers is not high enough.
Moreover, the cultivation of these talents requires a long process, which leads to the fact that China's shipbuilding technology level is gradually improving but still lags behind other countries.
Even if the mainland wants to quickly catch up with the past, there is no corresponding talent support, and at the same time, the mainland's technology is relatively small, and there is almost no technical reserve, which leads to the continent's lack of much breakthrough in technology.
These problems are not difficult for the technical personnel of the mainland shipbuilding industry, who have developed a new generation of intelligent shipbuilding cloud platform called "SWS TIME" through years of hard work.
This shipbuilding platform mainly uses big data to solve the problem of complex construction and limited technology.
The platform can carry out data design of the construction process, so as to achieve accurate control of the construction process and significantly improve the construction efficiency.
Through visual design, the appearance of the whole ship and the internal systems can be reasonably arranged to ensure the operation coordination and safety between each system.
The platform provides online design, resource management, project progress tracking and other functions, enabling shipbuilders to monitor construction progress in real time and optimize resource allocation.
Help designers and engineers identify potential problems at an early stage by intelligently recommending and simulating construction, thereby reducing the need for late modifications and rework, and improving construction efficiency and quality.
The emergence of this shipbuilding cloud platform undoubtedly provides great convenience for the process of building luxury cruise ships, and it can be said that without its help, China would not have been able to achieve results in the construction of luxury cruise ships with the technical level at that time.
Nevertheless, the great construction of luxury cruise ships still requires advanced technology from Italy.
Technical difficulties in building luxury cruise ships.
As we all know, Italy has advanced technology in luxury cruise ships, and almost all luxury cruise ships have Italy technology involved.
Although China's shipbuilding technology has made great progress, Italy's advanced technology is still needed for luxury cruise ships.
Because although we are already very skilled in building other types of ships, the construction of luxury cruise ships is very different compared to other types of ships.
In terms of the power of the vessel, the power of the merchant ship type is mainly provided by fuel, while the power of the luxury cruise ship type is mainly provided by electricity.
Some people may ask, can't luxury cruise ships rely on fuel like other ships?
In fact, no, the main reason why luxury cruise ships use electricity to provide power is because there are many entertainment facilities on luxury cruise ships, and if fuel is used to provide power, many harmful substances will be used to affect the experience of tourists.
Therefore, in order to ensure the experience of tourists on luxury cruise ships, and at the same time to ensure the safety of the whole ship, luxury cruise ships are powered by electricity.
Moreover, the power of a luxury cruise ship must be balanced between the hull and the center of gravity, which is extremely important and is related to the safety of the entire luxury cruise ship.
This requires the builder of a luxury cruise ship to make precise calculations in order to arrive at a balanced solution.
And Italy's shipbuilding technology accounts for a large proportion in the construction of luxury cruise ships.
No matter how good China's technology is, there is no way to realize the construction of luxury cruise ships with China's own technology.
Even the exterior walls of luxury cruise ships could not be treated perfectly, and our technicians conducted many experiments, but to no avail.
In the end, I had to ask Italy for support, and Italy's technical personnel were also very willing to share their technology with China.
The construction of a giant cruise ship was successful.
The cooperation between China's giant cruise ships, which involved Italy technology, has enabled China to make a breakthrough in the construction of luxury cruise ships.
To date, the H1508 is a luxury cruise ship that has been built to no small extent.
This is not only a breakthrough in China's shipbuilding industry, but also a great progress made by China in shipbuilding technology.
Behind such a seemingly simple construction process is the efforts of generation after generation of Chinese shipbuilding industry.
Just building a luxury cruise ship does not mean that the mainland shipbuilding industry has ushered in development opportunities.
The mainland's shipbuilding industry still has many breakthroughs in technology, and the mainland still has a long way to go on this road in the face of future market demand.
At the same time, the cruise construction industry has also brought huge development opportunities for the mainland's tourism industry, and now there are countless tourists in the mainland who choose to travel by cruise.
The experience of luxury cruise travel is not available in other modes of transportation, you can enjoy the wonderful scenery on the cruise, and there are many entertainment facilities on board for tourists to play and enjoy.
This obviously adds a lot of points to the experience of tourists, and the future development potential of the cruise industry is huge, and it will also bring greater highlights to the mainland's tourism industry.
The results of the construction of giant cruise ships will undoubtedly promote greater progress in the mainland's shipbuilding industry, and at the same time open up new business opportunities for the mainland's tourism industry.
epilogue
The construction of China's giant cruise ship marks a great breakthrough in the field of shipbuilding in the mainland, and it is also the efforts and achievements of generations of the mainland's shipbuilding industry.
In the future, there are still many breakthroughs to be made in the shipbuilding industry of the mainland, and at the same time, innovation and research and development are constantly being carried out.
We look forward to the mainland's shipbuilding industry to make greater achievements in the future and bring more development opportunities to the mainland's tourism industry.
