China Shipping & Sinopec Suppliers, a bunker trading company backed by Sinopec and COSCO Shipping, has completed China’s first-ever ammonia bunkering operation.
The bunkering operation involved refueling ammonia-powered tugboat Yuantuo 1 which was developed as part of COSCO Shipping Heavy Industry’s project “R&D and Demonstration Application of Ammonia-powered Dual-fuel Engine and Supply System”.
The milestone truck-to-ship operation was conducted on December 24, 2024, at Dalian COSCO Shipping Heavy Industry which has built the demonstration tugboat.
“The successful bunkering has effectively tested the integrity and efficiency of the company’s bunkering equipment system, gathered valuable knowledge and experience for the deployment of ammonia fuel in large vessels,” COSCO Shipping said in a brief social media update.
