On September 22, CCTV4 broadcast "Interview with Lu Jian·Conversation with Chen Gang". Chen Gang, chief designer of China State Shipbuilding Corporation's "Aida·Modu" cruise ship, and host Lu Jian jointly decrypted "How China's first large-scale cruise ship was built" " When Chen Gang introduced that "weight control is the key to design and construction," he pointed out that CSSC and NISCO repeatedly developed and finally controlled the thickness tolerance of the steel plate from the conventional 0.3 mm to 0.15 mm, realizing the localized supply of thin plates for cruise ships.
The first domestically produced large-scale cruise ship "Aida·Modu" will sail on an international route with Shanghai Wusongkou International Cruise Port as its home port on January 1, 2024, marking the Chinese people taking a large cruise ship made in China to go to sea and see the world, make dreams come true. "Aida·Modu" is exclusively supplied by NISCO with steel plates and marine sections for luxury cruise ships. At this historic moment when China's shipbuilding industry achieved zero breakthrough in the field of large-scale cruise ship construction and won the "last jewel in the crown" of the shipbuilding industry, NISCO and its subsidiary Suqian Nanjing Nangang Jinxin both received awards from China State Shipbuilding Corporation Shanghai Overseas High Letter of thanks from Bridge Shipbuilding Co., Ltd. This is enough to prove that the first domestically produced large cruise ship has had a significant and far-reaching impact on my country's construction of a maritime power, a manufacturing power, and a science and technology power.
Large luxury cruise ships are called "sea giants". They are a "moving city" and a huge systematic project. As the most complex single electromechanical combination in the world, large luxury cruise ships have high technical content and are extremely difficult to design and build. They reflect a country's equipment construction capabilities and comprehensive scientific and technological level. Together with aircraft carriers and liquefied natural gas carriers, they are known as the world's most complex. The three "crown pearls" of the shipbuilding industry represent the "supreme level" of today's global shipbuilding industry. The birth of "Aida·Modu" marks that China has become the fifth country in the world capable of building large cruise ships after Germany, France, Italy and Finland.
The center of gravity of the large luxury cruise ship is relatively high. In order to ensure the navigation safety of the cruise ship, the safety of the hull operation, the construction progress, and the comfort and aesthetics, etc., the weight of the steel plate, the unevenness of the entire plate, welding deformation, steel plate size, thickness tolerance, plate shape, etc. Strict requirements have been put forward in terms of quality and welding efficiency. More than 80% of the steel plates used on the cruise ship "Ada Magic City" are thin steel plates with a thickness of 4-8 mm. Through equipment upgrading and process technology research, NISCO Plate Division has achieved precise control of the thickness tolerance of 4 mm thick steel plates, solved the world-wide problem of shape and thickness control of wide and thin plates, broke through the extreme specifications of medium and thick plate production. It has laid the foundation for stable production and supply of products.
The flat ball steel required for large luxury cruise ships has extremely high welding requirements. Suqian Nangang Jinxin provides customers with personalized one-stop solutions. The products fill the domestic gap and solve the problems of small batch size, fixed length, precise size, etc., and To achieve professional, differentiated and directional services, we can meet the special technical requirements of on-site laser welding and non-laser welding of customers. Nangang Jinxin has achieved 100% exclusive supply of flat steel for the cruise ship "Aida·Modu".
The successful development and supply of NISCO products to the country's first luxury cruise project laid a material foundation for the localized construction of large-scale luxury cruise ships and enhanced the international competitiveness of China's steel products. Chen Gang introduced in the program that NISCO production of high-specification and high-standard thin plates is a very big breakthrough in the shipbuilding industry.
