Japanese energy company Osaka Gas on Friday (4 September) said it has successfully completed the first-ever ship-to-ship LNG bunkering operation in Osaka Bay, supplying LNG fuel to an LNG-fuelled PCTC. The operation was conducted using S ETO AZURE , an LNG bunkering vessel owned by Osaka Bay LNG Shipping Co Ltd, an affiliated company of Osaka Gas. Acting through Integr8 Fuels Pte Ltd, a Singapore-based marine fuel trading company, Osaka Gas supplied LNG fuel to an LNG-fuelled PCTC operated by an overseas shipping company calling at the Port of Kobe. Ship-to-ship bunkering will help ensure a stable supply of LNG fuel in the Osaka Bay area and support the development of the Port of Kobe as a Carbon Neutral Port. In addition to ship-to-ship bunkering, Osaka Gas provides LNG fuel through truck-to-ship bunkering and port-to-ship bunkering. With capability covering all three major LNG bunkering methods, Osaka Gas provides flexible and reliable LNG fuel supply services to meet customers’ diverse needs. The company said LNG bunkering infrastructure in Japan remains insufficient, highlighting the need to establish a stable fuel supply network to support the wider adoption of LNG-fuelled vessels.   Photo credit: Osaka Gas Published: 8 September, 2026
