South Korea’s Hanwha Ocean has marked a historic achievement by completing the world’s first liquefied natural gas (LNG) ship-to-ship (STS) transfer during sea trials. The successful operation demonstrates the shipbuilder’s growing leadership in advanced LNG technology and energy-efficient vessel design.

The test took place off Geoje Island, where two LNG carriers under Hanwha Ocean’s construction performed a full transfer of cryogenic fuel while both vessels remained underway. The trial validated the yard’s integrated LNG cargo handling and transfer systems, confirming their reliability and safety under real-world conditions.

This achievement represents a significant advancement in the decarbonization of maritime transport, as LNG continues to serve as a transitional energy source in the global shipping industry. Hanwha Ocean stated that the success not only highlights its engineering capabilities but also supports its ambition to lead innovations in next-generation green vessel solutions.

With this milestone, Hanwha Ocean strengthens its position as a key player in the global LNG carrier market, further reinforcing South Korea’s reputation as a world leader in shipbuilding technology.
