从“十年磨一剑”到“一年磨十剑” 中国LNG船建造效率大幅度提升

Core Viewpoint - The article highlights the significant advancements in the domestic production of Yinvag Steel, a core material for LNG ship construction, during China's 14th Five-Year Plan period, marking a shift from reliance on imports to breakthroughs in domestic technology [1][5]. Group 1: LNG Ship Construction - The construction of an LNG ship is compared to that of an aircraft carrier, with over 3 million components involved in the enclosure system alone, requiring expertise in fluid mechanics, low-temperature materials, and automatic control [3][5]. - The Yinvag Steel used in LNG ship welding is extremely thin at 0.7 mm, with a welding error tolerance of just 0.1 mm, illustrating the precision required in the construction process [3][5]. Group 2: Technological Advancements - The technological breakthroughs achieved during the 14th Five-Year Plan have led to a significant increase in construction efficiency, reducing the production time for a large LNG transport ship from over 30 months to 17 months [7]. - The China Shipbuilding Group has collaborated with over 300 domestic supporting enterprises to create an "innovation consortium" that encompasses the entire industry chain, facilitating multiple technological advancements in LNG ship construction [5][9]. Group 3: Future Aspirations - The leadership at the China Shipbuilding Group emphasizes a shift in approach, aiming to achieve in one year what previously took ten years, reflecting a commitment to rapid innovation and efficiency in shipbuilding [9].
