The Ulsan Port Authority successfully conducted green ammonia fuel supply operations amounting to approximately 800 tons for the Terra Clove vessel, the world's first dual-fuel ammonia ship. This vessel, with a capacity of 93,000 cubic meters, was recently built by Eastern Pacific Shipping (EPS) in collaboration with HD Hyundai Heavy Industries.
Details of the Fuel Supply Operation
The fuel supply operation took place on October 25 and 26, 2026, at Pier 2 of Ulsan Port in South Korea. Green ammonia fuel was supplied using the Pipe-to-Ship (PTS) fueling method, where the fuel was directly transferred from the coastal facilities of Ulsan Port to the vessel.
Key Collaborations in the Operation
This operation is considered a milestone in the supply of alternative fuels and was conducted through a public-private partnership coordinated by EPS and HD Hyundai Heavy Industries, as well as LOTTE Fine Chemical, which supplied the fuel. Byun Jae-young, the head of Ulsan Port, stated: "This project demonstrates the importance of collaboration and coordination with relevant authorities and industry partners to advance the ammonia fuel supply operations at Ulsan Port and in South Korea."
He also added: "With ongoing efforts, we aim to establish Ulsan Port as a key hub for supplying alternative marine fuels." The fuel supply operation for Terra Clove is the latest of several ammonia fuel supply operations that Ulsan Port has conducted to develop the necessary infrastructure and operational framework for commercial ammonia fuel supply services.
In April 2026, Ulsan Port conducted its first green ammonia fuel supply operation by supplying approximately 600 tons of fuel for a 45,000-ton class tanker using the PTS method.
