Amogy, C-Job set to retrofit tug for ammonia fuel

C-Job applied risk-based design on this project, which will push the boundaries of what is possible in terms of using ammonia as a fuel for workboats. Risk-based design is used extensively where overall safety follows from the application of functional rules and risk assessment.

This methodology was applied to design areas including mitigating ammonia emissions, design precautions around potential leaks, and principal design choices to manage hazardous and dangerous zones.

“The to-be-converted vessel will be considered a hybrid vessel with an ammonia-to-electricity power source using Amogy’s technology,” said Mr Stoit.

“With our extensive and broad maritime knowledge of newbuilds, converting and repowering vessels with modern and out-of-the-box technology, and our holistic approach towards all systems in the vessel, together we can make the difference to a scalable and worldwide applicable system towards a greener shipping industry.”

C-Job is an advocate of ammonia as a marine fuel. It published a report in 2019 showing it is possible to safely implement ammonia as a marine fuel when safety measures are included in the design.

There are plans to retrofit tugboat Sakigake in Japan to be powered by ammonia, led by leading Japanese shipowning group NYK and involving ClassNK classification society and international technology groups, with completion expected 2024.
