“十五五”开好局起好步丨我国绿色船舶制造加速实现自主配套

Core Viewpoint - The shipbuilding industry in China, particularly in the construction of high-value green ship types, is becoming a significant part of the national maritime strategy and a new global calling card for the country [1] Group 1: LNG Ship Construction - China State Shipbuilding Corporation (CSSC) is actively constructing multiple large LNG (Liquefied Natural Gas) carriers at its Hudong-Zhonghua Shipbuilding facility [1] - A single 174,000 cubic meter LNG carrier requires approximately 60,000 insulation boxes, which serve as a thermal protection system to ensure the safe and stable transport of LNG at ultra-low temperatures [3] Group 2: Insulation Box Production - The automated production line at the insulation box manufacturing facility can produce around 430,000 insulation boxes annually, meeting the self-supply needs of the shipyard for LNG carrier construction [3] - The insulation boxes must meet precise specifications, capable of withstanding extreme low-temperature environments, ensuring the stability and safety of LNG during long-distance maritime transport [5] Group 3: Automation and Innovation - The production line for insulation boxes has been developed in collaboration with Shanghai Jiao Tong University, incorporating intelligent control systems and automated machinery, which has doubled assembly efficiency and improved product quality [7] - Each completed insulation box is assigned a "digital ID" for tracking, and the intelligent warehouse system allows for efficient and precise storage and retrieval of different box models [9] Group 4: Future Development and Industry Upgrades - The breakthrough in insulation box production is seen as a microcosm of the broader goal to upgrade the entire LNG ship domestic supply chain, including the development of low-temperature valves, which are also critical components of the LNG delivery system [11] - Future plans include collaboration with domestic universities and supply chain enterprises to enhance the overall intelligent manufacturing process and increase the domestic production rate, aiming for better performance, lower costs, and stronger competitiveness of Chinese-built LNG ships [13][15]
