Ulsan Port Advances Commercial Green Ammonia Bunkering Capabilities with 800-Tonne Fuel Supply to World’s First Ammonia Dual-Fuel VLAC

The Ulsan Port Authority (UPA) has further strengthened its position in the alternative fuels market after successfully conducting a major commercial green ammonia bunkering operation for Terra Clove, the world’s first ocean-going ammonia dual-fuel Very Large Ammonia Carrier (VLAC).

UPA successfully completed the demonstration of supplying approximately 800 tonnes of green ammonia to Terra Clove, a newly launched 93,000 m3 VLAC from Eastern Pacific Shipping (EPS) built by HD Hyundai Heavy Industries. The operation took place from October 25-26, 2026 at Pier 2 of Ulsan Main Port in South Korea.

The green ammonia was supplied using a Pipe-to-Ship (PTS) bunkering method, in which the fuel was transferred directly from Ulsan Port’s shore-based facilities to the vessel through a pipeline.

UPA’s milestone operation was carried out through a public-private partnership, in coordination with EPS and HD Hyundai Heavy Industries, as well as LOTTE Fine Chemical, who supplied the fuel.
