Recently, Osaka Gas christened the SETO AZURA vessel to be used exclusively for LNG supply under the ship-to-ship model. The ceremony took place at the Shitanoe Shipbuilding shipyard, where the vessel’s name was officially confirmed. It is set to begin operational sailing in April 2026.
Expanding the LNG transfer and supply network
Osaka Gas’s strategy aims to strengthen the supply of clean fuel for large capesize bulk carriers operated by consortia such as MOL, K LINE and NYK. With a tank capacity of approximately 3,610 m³, the SETO AZURE will enable refueling of deep-draft vessels operating in and around the Seto Inland Sea.
Likewise, this unit features a dual-fuel electric propulsion system. This configuration allows it to use both LNG and conventional fuel oil, optimizing the vessel’s operational efficiency. Implementing this direct ship-to-ship transfer method complements the company’s previous capabilities, which operated via truck-to-ship and terminal-to-ship systems.
The deployment of this bunkering vessel follows the International Maritime Organization’s guidelines on reducing pollutant gases. LNG is currently the most viable bridge to reduce carbon dioxide on global trade routes. However, the Daiga Group envisions a future beyond fossil fuels through the development of synthetic e-methane.
Under the Energy Transition 2050 strategic plan, the use of e-methane is positioned as the natural successor to liquefied natural gas. This approach ensures that current investments in LNG infrastructure remain compatible with tomorrow’s fuels. The SETO AZURE’s versatility ensures Japan maintains its competitiveness in marine energy supply while meeting global sustainability targets.
