Bunkering is an indispensable operation to supply fuel to ships. Currently in marine industry, ammonia has been a bulk commodity frequently loaded/unloaded from terminal to ship or ship to terminals. The operation is similar to bunkering, the difference being that ammonia is transferred to a dedicated storage tank instead of fuel tank. The future adoption of green ammonia as a marine fuel will need to be developed taking reference of the existing industry practice, of which the bunkering operation is carried out for heavy fuel oil, diesel oil, marine gas oil, lube oil and LNG. There is also a need to study the measures needed to mitigate the impact of ammonia bunkering near populated area.
