“…When the flow rate varies from 500 to 1,500 m 3 /h, the consequence of ammonia release would be severe, and the 3% lethality footprint would be larger. Yang and Lam [67] conducted a sensitivity analysis of bunkering supply and demand configurations and concluded that flow rate greatly influences ammonia bunkering service time. Another constraint of selecting bunker hose size and flow rate is the consideration of fluid dynamics, such as water hammer effects during ammonia transfer.…”

“…Furthermore, the development of ammonia-fuelled marine engines and fuel cells is currently underway at a pre-commercialisation stage [18,53,61]. Ammonia bunkering operations play a vital role in linking upstream supply and downstream consumption in the ammonia bunker supply chain [67]. However, limited literature exists on ammonia bunkering, particularly from the safety and risk perspective.…”

“…Liu et al [21] proposed a heuristic algorithm for solving the LNG bunkering problem, including decisions to assign ships to tanks, manage the inventory of the tanks, and schedule LNG trucks for bunkering ships and replenishing tanks. Moreover, Yang and Lam [22] developed a simulation model of the bunker supply chain and evaluated the impact of ammonia bunkering, another alternative fuel other than LNG.…”

Despite the increased demand for alternative fuel bunkering and the importance of its base formation, quantitative information or statistics on bunkering are very limited due to data availability. This study aims to develop a quantitative method to extract bunkering operations and analyze and compare the actual bunkering operations, such as bunkering service times and starting times in the port area, by extracting anchored vessels using a clustering method and matching them with bunker barges spatio-temporally. The algorithm also reflects the characteristic behavior of bunker barges, including calling at refineries and bunker barge bases. This study then focuses on bunkering in three port areas and compares their characteristics from various perspectives. The study’s key findings reveal variations in vessel types and service times across three port areas, particularly in Tokyo Bay, where shorter service times are observed for containerships and dry bulk carriers due to high fuel prices. Additionally, it highlights differences in bunkering start times, with Tokyo Bay for daytime operations and Singapore Port for a more balanced distribution throughout the day. Furthermore, bunkering locations differ, with Tokyo Bay and Busan Port having most operations at container terminals, while offshore bunkering is prevalent in Singapore Port.

For the global transport and trade of hydrogen, ship transport is of central importance. Ammonia is a promising option for this task. In the ammonia molecule, hydrogen is stored through chemical bonding to nitrogen. In comparison to liquid hydrogen, liquid ammonia shows a higher volumetric energy density and shows advantages in terms of handling. To establish ammonia as a global climate‐neutral energy carrier, the production of green ammonia as well as an efficient supply chain plays important factors. Terminals are an essential part of the process chain as they enable the transshipment from ship to land and vice versa. In this study, the efficiency of various ammonia terminal concepts dealing with both pressure‐liquefied and cold‐liquefied green ammonia is targeted. Multiple terminal concepts are analyzed by thermodynamic investigation as well as numerical simulation. The concepts are compared by system behavior as well as electricity and heat demand under typical bunkering scenarios. The analysis of the concepts produces general design criteria for an efficient terminal design. It is shown that an export terminal is most efficient with a multistage expansion. Furthermore, the integration of the pressure tank as a condenser proves to be particularly suitable for an import terminal.
