Large-scale cruise ships are called "star hotels sailing at sea" and are the only unfinished high-tech and high-value-added ship products in China's shipbuilding industry. Compared with aircraft carriers and LNG ships, the construction of large cruise ships is more difficult. The industrial chain of large cruise ships is very long. In the construction process, more than 500 global suppliers are needed to provide core components, and more than 65,438+0,000 all suppliers and more than 50 global service providers provide cooperation.
In addition, the construction of a cruise ship also needs the knowledge and technology of dozens of professional fields such as hotel engineering and entertainment system. Building a large cruise ship requires a country with high-level equipment construction capability and comprehensive scientific and technological level.
Large cruise ships have the following characteristics:
1. Huge volume: Large cruise ships usually have a gross tonnage of over 6,543,800 tons, a length of over 300 meters, a width of over 30 meters and a height of over 50 meters. Its size is equivalent to a small city, which can accommodate thousands of people living and moving at the same time. This huge volume requires strong structural design and construction capabilities.
2. Rich functions: There are various facilities and projects on large cruise ships, such as restaurants, bars, cafes, shopping centers, theaters, cinemas, casinos, swimming pools, water parks, spas, gyms, libraries, museums, etc. Passengers can enjoy five-star service and various marine entertainment activities. These facilities and projects need careful design and layout to provide a comfortable and enjoyable experience.
3, high performance requirements: large cruise ships have to withstand various challenges in the marine environment, such as wind and waves, salt fog, corrosion, vibration and so on. Therefore, high-strength structural design is needed to cope with the turbulent environment at sea. At the same time, large cruise ships also need efficient power systems to provide sufficient propulsion and sailing speed. Navigation control system also needs high precision to ensure the navigation safety of cruise ships.
