With the improvement of people's living standards, more and more people go out to travel. my country has an extremely rich water system landscape: there are more than 10,000 kilometers of coastline, the Bohai Sea, the Yellow Sea, the East China Sea, and the South China Sea, as well as the two major islands of Taiwan and Hainan and thousands of small islands; there are Yangtze River, Yellow River, Heilongjiang, Songhua Hundreds of navigable rivers such as the Yalu River, the Beijing-Hangzhou Canal, the Pearl River, the Lancang River, the Huaihe River, the Xiangjiang River, the Ganjiang River, the Qiantang River, the Minjiang River, and the Jialing River; dozens of lakes such as Panyang Lake, Hongze Lake, Dongting Lake, and Honghu Lake Lakes are holy places for water tourism. Therefore, cruise ships will be a star product with broad prospects.

Aluminum is an excellent material for manufacturing superstructures and structures of cruise ships. The superstructure and facilities include: guardrails, partition walls, floors (with patterned anti-skid plates), ladders, furniture, daily necessities, kitchen utensils, fire doors, etc. Using aluminum alloy materials to manufacture cruise ship upper-level facilities has the following advantages: Under the same performance conditions, the aluminum structure and workpiece are about 40% to 45% lighter than steel; clean and hygienic, bright in color, and do not require maintenance during the service period, unlike Like the steel structure, it must be maintained every three to five years, otherwise it will be rusty, which is not only ugly, but also may cause small accidents or unpleasant things; the biggest feature of aluminum is that although it is not a direct fireproof material , but it is beneficial to fire prevention, because aluminum will absorb a lot of heat when it is on fire, and melt quietly, which helps to reduce the fire, and unlike magnesium, it will burn scary and violently when it encounters an open flame, so it is not suitable to use magnesium. The superstructure and facilities of the cruise ship; after the cruise ship expires and is scrapped, the aluminum structure can be completely recycled, and there will be at most 5% mechanical loss. The recycling price of waste materials is equivalent to 80% of the price of the original aluminum ingot at that time; Both fresh water and sea water have strong corrosion resistance, so they are naturally superior materials for manufacturing cruise ships; and the price of aluminum is reasonable and moderate, which is competitive.

With the proposal of the "Double Carbon" goal, the power energy used by cruise ships will undoubtedly develop towards the goal of new energy, especially pure electric cruise ships will be the development direction, river, lake and river cruise ships can be pure electric, and coastal cruise ships can also be pure electric Yes, large transoceanic cruise ships are currently driven by pure electricity, which may still be difficult. The largest pure electric cruise ship designed and manufactured by China itself is the Yangtze River Three Gorges No. 1 cruise ship, which began to carry passengers on March 29 this year. The ship has a total length of 100m, a total width of 16.3m, a molded depth of 4m, and a passenger quota of 1,300. It is invested by Hubei Three Gorges Tourism Group affiliated to Yichang Chengfa Group and Yangtze River Electric Power Company affiliated to Three Gorges Corporation. It is manufactured by Yichang Zhijiang Xinhui Shipyard. The pure electric cruise ship with the largest load capacity and the highest degree of intelligence costs about 150 million yuan in research and development and construction.

The Yangtze River Three Gorges No. 1 cruise ship is equipped with 7,500 kWh marine power batteries, which is equivalent to the total battery capacity of 100 pure electric vehicles, and can last 100 kilometers on a single charge. It can replace 530 tons of fuel oil every year and reduce more than 1,600 tons of greenhouse gas emissions. The cruise ship is also the world's first electric ship that adopts high-voltage charging and low-voltage power supply mode, which efficiently solves the charging problems and bottlenecks that have been plagued by high-power ports. The Yangtze River Three Gorges No. 1 cruise ship is a high-tech ship scientific research project of the Ministry of Industry and Information Technology and a pilot project of the Ministry of Transport for a strong country in transportation, which has promoted the rapid development of clean energy and green and low-carbon transportation.

my country is a big country in the world's aluminum industry, and it is also a big country in the world's aluminum processing industry. In 2021, the production capacity of aluminum processing materials and deep-processing products will account for about 70% of the world's total. The material can be produced in our country. 5XXX series and 6XXX series alloys can be used for the production of superstructures and facilities of cruise ships and cruise ships.
