Why are domestically built large cruise ships classified as major technical equipment? This article from Science Popularization China, based on interviews with cruise ship R&D personnel from China State Shipbuilding Corporation, introduces the complexity of large cruise ships in design and construction, as well as the technical challenges behind the push for domestic production.
The article points out that large cruise ships are not merely means of transportation, but a "giant systems engineering" project that balances passenger experience, comfort, safety, and commercial operating efficiency. A cruise ship involves more than 25 million parts and over 100 systems, with detailed design drawings numbering in the thousands; it must achieve highly coordinated system integration within limited space, cost, and time.
The R&D personnel explained that the key difficulties in domestically built large cruise ships include weight control, safe return to port, vibration and noise reduction, and cabin sound insulation. Since cruise ships are extremely sensitive to weight, details such as tables, chairs, and carpets must all be incorporated into the design. The noisecontrol requirements for cruise ship cabins are also higher than those for ordinary ships. Relevant teams improve construction precision and the onboard experience through digital twins, modular design, new materials, and structural optimization.
The article also mentions that the domestically built cruise ship project has advanced the development of the industrial system and the replacement of imported products with domestic ones. The first two ships mainly relied on introduction, digestion, and absorption, while subsequent ship models are planned to gradually increase the domestic content rate in order to reduce supply chain uncertainty and dependence on external technologies. The related technical experience is also expected to extend to more fields such as cargo ships, offshore engineering vessels, buildings, airp
