The Port of Dampier in the Pilbara region of Western Australia witnessed the successful completion of the world's first ship-to-ship ammonia transfer at anchorage on September 14, 2024. Led by a consortium that included the Global Centre for Maritime Decarbonization (GCMD), the Pilbara Ports Authority, and Yara Clean Ammonia (YCA), the operation aimed to establish Pilbara as a major ammonia bunkering hub and promote ammonia as a viable maritime fuel. The transfer involved two ship-to-ship operations between the Green Pioneer and Navigator Global ammonia carriers, with each transfer handling around 4,000 cubic meters of ammonia. The successful completion of these transfers is expected to enhance Pilbara's status as a low-greenhouse gas (GHG) emission ammonia bunkering hub, aligning with previous studies indicating the region's suitability for ammonia bunkering. Safety was a top priority during the operation, with various measures such as emergency release couplings, shutdown devices, and extensive risk assessments, including Hazard Identification and Hazard and Operability examinations, ensuring a secure transfer process. A Computational Fluid Dynamics (CFD) dispersion analysis confirmed safe operational limits, with the ammonia plume length kept below one nautical mile. The successful transfer received positive feedback from industry stakeholders, with Yara Clean Ammonia highlighting it as a substantial step towards decarbonizing shipping. The initiative is set to benefit ongoing decarbonization projects in Pilbara, including the development of a renewable ammonia production facility at Yara's Pilbara site. Additionally, the Global Centre for Maritime Decarbonization intends to leverage insights from the pilot to explore ammonia transfer feasibility at other ports and further enhance ammonia bunkering infrastructure. Overall, the successful ship-to-ship ammonia transfer in the Port of Dampier marks a significant milestone in advancing sustainable maritime practices, showcasing the potential of ammonia as a low-GHG emission fuel for the shipping industry.
