The world’s first ship-to-ship transfer of ammonia using vessels at anchorage in a working port environment has been completed. The transfer is a significant step towards realizing ammonia as a shipping fuel and enable bunkering worldwide. Yara contributed with their experience and knowledge on safe handling of ammonia, nominated an ammonia vessel from their Time Charter fleet, and the ammonia used in the transfers.

“This demonstrates that ammonia transfer can be done with the highest safety standards and efficiency in a working port environment. The transfer is a major milestone to decarbonize shipping using low-emission ammonia as fuel,” says Murali Srinivasan, SVP Commercial Yara Clean Ammonia.

The operation is a result of the collaborative relationship between Yara Clean Ammonia, Pilbara Ports Authority and the Global Centre for Maritime Decarbonisation (GCMD). It was conducted in Port Dampier in Western Australia’s Pilbara region, as part of the work to enhance the Pilbara’s potential as a bunkering hub to fuel ships with low-emission ammonia. Low-emission ammonia is produced with renewable energy and electrolysis of water or with carbon capture and storage. Ammonia does not emit CO2 when burned.

The Pilbara Ports Authority and Yara Clean Ammonia have been working together for more than two years investigating the potential demand for ammonia as a fuel, required bunker infrastructure, safety guidelines and the required regulatory framework. To develop the transfer, this partnership was expanded with GCMD, who successfully attracted additional partners to help ensure a safe and efficient execution of the transfer operation. Port Dampier has ongoing experience with ammonia cargoes with Yara Pilbara’s nearby operations shipping an incident free 11.8 million tonnes to date.

The two ship-to-ship transfers were undertaken between the Green Pioneer, 35,000 cubic metres (cbm) ammonia carrier (owner MOL), and the Navigator Global, a 22,500 cbm ammonia carrier (owner Navigator Gas). The trial involved a dual transfer of 4,000 cbm (approximately 2,715 tonnes) of ammonia, first from the Green Pioneer to the Navigator Global, and then back to the Green Pioneer.

Murali Srinivasan, SVP Commercial Yara Clean Ammonia said collaboration on safety is innate to our thinking and we are very proud to be part of this tripartite project and active collaboration and contributions to the positive outcome of the trials.
