中国已初步建成绿色船舶和海上设施技术规范体系

Core Viewpoint - China has made significant progress in establishing a technical specification system for green ships and offshore facilities, contributing to the low-carbon and sustainable development of the shipping industry amid a global push for green transformation [1][3]. Group 1: Development of Technical Specifications - China has actively aligned with the International Maritime Organization (IMO) greenhouse gas reduction targets, systematically advancing the standardization of green ship technology, with the release of 15 technical specifications and 7 implementation guidelines related to green technology [3]. - The technical specification system covers green energy applications, energy efficiency improvements, and ecological protection, providing systematic support for the green development of the shipping industry [3]. Group 2: Green Energy Initiatives - The LNG ship technology system in China is becoming increasingly comprehensive, with over 600 LNG ships operating safely nationwide; the number of electric ships has surpassed 500, and demonstration operations for hydrogen fuel cells and battery-swapping technology have been achieved [3]. - Breakthroughs in new power technologies such as alcohol fuel and ammonia fuel are promoting the installation of "green hearts" in Chinese ships [3]. Group 3: Energy Efficiency Improvements - The Energy Efficiency Design Index (EEDI) has been fully implemented across three major types of transport vessels: bulk carriers, liquid cargo ships, and container ships, with approximately 1,500 ships optimizing their energy efficiency design each year [3]. - Energy-saving technologies such as wind rotors, hard-wing sails, and air lubrication systems are being rapidly promoted, allowing ships to "sail with the wind" [3]. Group 4: Ecological Protection Measures - Desulfurization devices and VOCs purification systems effectively reduce atmospheric pollutant emissions, while carbon capture devices and ballast water management systems create a "circular-regeneration" ecological system on ships, ensuring marine environmental protection [3][4]. Group 5: Future Developments - Cutting-edge green technologies such as nuclear energy and biofuels are also being incorporated into planning, continuously improving the blueprint for China's green ship and offshore facility technical specification system [4].
