The China Current: China's First Domestic Large-Scale Cruise Ship
第一艘國產大型郵輪
China's first domestic large-scale cruise ship has completed the main structure project in two years, and the appearance of the ship has taken shape.
The cruise ship is 323.6 meters long and 37.2 meters wide. There are more than 2,100 guest rooms and a 16-story living and entertainment area on the ship, which can accommodate more than 5,200 passengers and more than 1,000 employees. The construction cost is 5.4 billion yuan, which is equivalent to the value of 9 Boeing 737s.
Like aircraft carriers and liquefied natural gas (LNG) ships, large cruise ships are one of the most difficult to design and build, previously only Italy and Germany were able to build them. Generally, the number of parts required for large cruise ships reaches 25 million, which is far from super-high railways and large planes. The length of the cable used is over 5,000 kilometers, which is almost the same as the straight-line distance from Beijing to Moscow.
The hull is assembled in a 700-meter-long dock. The process is equivalent to "building blocks". First, the steel plate is cut into parts, the parts are assembled into segments, and the segments are combined into a total segment to form a block of building blocks, and the error during construction cannot exceed 20mm is very difficult.
Different from other civil ships, 80% of the cruise ship is made of steel sheets with a thickness of 4 to 8 mm due to strict requirements on the weight center and aesthetics. However, the sheets are easily deformed during processing and hoisting. Body structure dislocation.
The team built China's first 5G cruise intelligent thin plate assembly line, using laser cutting, laser hybrid welding, and robotic welding to solve the problems of thin plate cutting and welding. For the first time, a fully digital production mode has been introduced, and workers can see the workflow and details in real time through the mobile APP on site.
Compared with Europe and the United States, the Chinese cruise market started late, but it has developed rapidly. In the past 10 years, the number of cruise passengers has increased by 40-50% every year, and it is now the second largest source country of cruise passengers in the world. China currently has more than 15 cruise home ports, and the total profit of the cruise industry in 2019 even exceeded the total of the Americas and Europe. It is estimated that by 2035, the economic scale of China's cruise industry will exceed 400 billion yuan each year, creating 1.5 million jobs.
中國第一艘國產大型郵輪經兩年時間，完成主體結構工程，船隻外貌已經成形，之後會轉入內裝階段，將於2023年下半年交付。
這艘郵輪長323.6米、寬37.2米。船上2100多間客房及16層生活娛樂區域，可容納 5200 多名乘客、逾千名員工，造價54億元人民幣，相當於9架波音737的價值。
與航空母艦、液化天然氣(LNG)船一樣，大型郵輪是設計建造難度最高的船型之一，以前只得意大利和德國有能力建造。一般大型郵輪所需的零部件數量達2500萬個，遠超高鐵、大飛機等。所使用的電纜長度超過5000公里，差不多等如北京到莫斯科的直線距離。
船體組裝在一個700米長的船塢內進行，過程相當於「砌積木」，首先要把鋼板切成零件，零件拼成分段，分段組成總段，形成一塊塊積木，而搭建時誤差不能超過20毫米，難度很高。
與其他民用船隻不同，由於對重量重心和美觀度都有嚴格要求，郵輪80%部分都是厚度4至8毫米的鋼製薄板分段，但薄板在加工、吊運過程中容易變形，導致船體結構錯位。
團隊建設了中國第一條5G郵輪智能薄板流水線，採用激光切割、激光複合焊、機械人焊接，解決了薄板切割和焊接的問題。更首次引入了全數字化的生產模式，工人在現場可以通過手機APP，實時看到工作流程和細節。
中國郵輪市場與歐美相比起步較遲，但發展得很快，過去10年，郵輪旅客數字每年都有40-50%增長，現已是全球第二大郵輪客源國。 中國目前有超過15個郵輪母港， 2019年郵輪行業的利潤總額甚至超過了美洲和歐洲的總數。預計到2035年，中國每年郵輪產業經濟規模將突破4000億元人民幣，創造150萬個就業職位。
