中船集团首台大缸径氨燃料低速发动机顺利完成氨模式试航The first large-bore ammonia-fueled low-speed engine of China Shipbuilding Group successfully completed its ammonia mode sea trial
据中船动力集团消息，近日，由中船动力集团旗下中船青柴生产建造的CPGC/CSE-WinGD 6X72DF-A-1.0-HPSCR氨燃料低速发动机圆满完成氨模式试航。
试航结果显示，主机各项性能指标优越，燃烧后的氨气排放历史性地突破至10ppm以下，实现了氨气近零逃逸，得到船东、船厂、船级社各方高度认可，标志着我国绿色船舶动力装备在零碳转型领域取得里程碑突破。
氨燃料低速发动机以氨作为燃料，燃烧过程不产生二氧化碳，是航运业实现深度脱碳的重要技术路径之一。氨具有毒性和特殊的燃烧特性，对发动机设计、密封与安全控制提出很高要求，氨气逃逸控制更是行业公认的技术难点。此次氨模式试航成功，意味着我国在氨燃料船舶动力装备领域实现了从技术研发到实船验证的关键跨越。
中船动力集团是我国船舶动力装备领域的骨干企业。此次首台大缸径氨燃料低速发动机完成氨模式试航，主机各项性能指标表现优越，进一步巩固了我国在绿色低碳船舶动力领域的自主研制能力，也为全球航运业绿色转型提供了新的技术选择。
据了解，氨燃料低速发动机主要面向远洋船舶市场，与传统的燃油动力相比，氨燃料燃烧不产生二氧化碳，被认为是大型远洋船舶实现深度脱碳的重要方案之一。此次首台大缸径氨燃料低速发动机完成氨模式试航，体现了我国船舶动力企业在绿色低碳装备研发上的持续投入与自主创新能力。
业内认为，随着国际海事组织减排要求日趋严格，绿色船舶动力装备市场空间广阔。氨燃料发动机实现氨气近零逃逸，解决了氨燃料应用中的一大技术难题，为后续规模化装船应用奠定了基础，也为我国船舶工业在绿色低碳赛道抢占先机提供了有力支撑。
According to China Shippower Group, recently, the CPGC/CSE-WinGD 6X72DF-A-1.0-HPSCR ammonia-fueled low-speed engine, produced and built by China Shippower Group's subsidiary, CSSC Qingdao Diesel, successfully completed its ammonia mode sea trial.
The results of the sea trial show that the main engine's performance indicators are excellent, and the post-combustion ammonia emissions have historically reached below 10 ppm, achieving near-zero ammonia leakage. This has been highly recognized by shipowners, shipyards, and classification societies, marking a milestone breakthrough for China's green ship power equipment in the field of zero-carbon transition.
Ammonia-fueled low-speed engines use ammonia as fuel, and their combustion process does not produce carbon dioxide, making them one of the important technological pathways for the shipping industry to achieve deep decarbonization. Ammonia has toxicity and special combustion characteristics, which put high demands on engine design, sealing, and safety control, and controlling ammonia leakage is widely recognized as a technical challenge in the industry. The success of this ammonia mode sea trial signifies that China has achieved a key leap from technological research and development to full-scale vessel verification in the field of ammonia-fueled ship power equipment.
China Shipbuilding Power Group is a key enterprise in the field of ship power equipment in China. The first large-diameter ammonia-fueled low-speed engine successfully completed a trial voyage in ammonia mode, with all main engine performance indicators showing excellent results. This further consolidates China's independent development capabilities in the field of green and low-carbon ship power, and also provides new technological options for the global shipping industry's green transition.
It is understood that ammonia-fueled low-speed engines are mainly targeted at the ocean-going ship market. Compared with traditional fuel-powered engines, ammonia fuel combustion does not produce carbon dioxide and is considered one of the important solutions for achieving deep decarbonization in large ocean-going vessels. The completion of the first trial voyage in ammonia mode by the first large-diameter ammonia-fueled low-speed engine reflects the continuous investment and independent innovation capabilities of China's ship power enterprises in the research and development of green and low-carbon equipment.
Industry experts believe that as international maritime emission reduction requirements become increasingly stringent, there is broad market potential for green ship power equipment. Ammonia-fueled engines achieve near-zero ammonia leakage, solving a major technical challenge in the application of ammonia fuel, laying a foundation for subsequent large-scale ship applications, and providing strong support for China's shipbuilding industry to gain an early advantage in the green and low-carbon sector.
