Hanwha Ocean completes world’s first ship-to-ship LNG transfer during sea trials
Hanwha Ocean has announced the successful completion of the world’s first ship-to-ship (STS) transfer of liquefied natural gas (LNG) carried out during sea trials. The operation represents a new milestone in gas-trial procedures and could redefine testing standards for LNG carriers.
In brief
Hanwha Ocean carried out the world's first ship-to-ship LNG transfer during sea trials, between the tankers Maran Gas Syros and Woodside Jirrubakura. The operation was performed at sea, without the use of terminal infrastructure, which shortens the delivery time of new vessels and reduces emissions. Previous LNG tests required the use of terminals, generating a risk of delays and additional logistics costs. Hanwha Ocean points out that the achievement builds on its earlier world-first STS LNG transfer within the Okpo shipyard.
According to information released in early October by LNG Prime, the operation was conducted between the LNG carriers Maran Gas Syros and Woodside Jirrubakura, both built by Hanwha Ocean. The transfer was completed at sea, without the use of terminal infrastructure.
Traditionally, LNG gas trials require terminal access for loading and discharge operations, often causing scheduling delays and logistical costs. Hanwha Ocean’s method enables direct LNG transfer between vessels under sea-trial conditions, significantly reducing turnaround time, environmental impact, and dependency on onshore terminals.
The company noted that this development builds on its earlier achievement of the world’s first STS LNG bunkering within a shipyard environment at Okpo. The successful offshore transfer demonstrates the maturity of Hanwha Ocean’s LNG handling systems and operational safety protocols.
Industry observers see this as a potential new benchmark for LNG-carrier commissioning processes, reinforcing Korea’s leadership in advanced shipbuilding and LNG transfer technologies.
Hanwha Ocean, formerly known as Daewoo Shipbuilding & Marine Engineering (DSME), is among the world’s leading builders of LNG carriers and low-emission vessels. The company continues to invest in technologies supporting cleaner maritime operations and next-generation gas-handling systems.
