On March 16, witnessed by representatives from classification societies—including LR, ABS, and CCS—as well as shipowners and shipbuilders, the first WinGD 6X72DF-A-1.0 ammonia-fueled low-speed engine, manufactured by CSSC Engine Co.,Ltd. (CSE), successfully passed its Functional Integration Test (FIT) and Factory Acceptance Test (FAT), and was successfully delivered. As China’s first ammonia-fueled marine engine to be formally delivered to the market, it fills a gap in the application of zero-carbon marine propulsion technology in China.
According to reports, the 6X72DF-A-1.0 HPSCR ammonia-fueled low-speed engine undergoing acceptance testing has a rated power of 14,400 kW and a maximum speed of 67 rpm. It will be installed on a 210,000 DWT bulk carrier being built by Beihai Shipbuilding for CMB.
The main engine is equipped with WinGD’s latest WiCE control system, along with peripheral systems such as FVU, AICWS, AFSS, AVPS, and GDS. This configuration ensures a stable supply of liquid ammonia and efficient operation of the main engine, while also enabling intelligent, real-time monitoring of liquid ammonia leaks in both the main engine and the test facility. This comprehensively guarantees the superior performance of the main engine, as well as the stability, reliability, and safety of ammonia-mode operation.
Currently, CSE has established the capacity for mass production of ammonia-fueled low-speed engines. The company now operates four assembly and test stations for these engines, with an annual production capacity of over 20 units, meeting market demand for zero-carbon marine propulsion systems.
The successful delivery of the first ammonia-fueled low-speed engine represents a significant step by CSE in implementing the national “dual carbon” strategy, accelerating its green transition, and achieving high-quality development. It marks the company’s entry into the forefront of the global zero-carbon marine propulsion sector.
