Massive 310,000-ton LNG supertanker stretches 1,114 feet, targets 85% less NOx

Japan has just delivered a giant liquefied natural gas (LNG) tanker that could cut nitrogen oxide (NOx) emissions by up to 85 percent and carbon dioxide (CO2) emissions by 30 percent.

Named Tsurugidake, the massive vessel was built by Tokyo-based Kawasaki Heavy Industries and delivered to Sequoia Navigation Inc. at a shipyard in Dalian, China on October 14, 2026. It is 1,114 feet (339.5 meters) long and boasts a deadweight capacity of 310,020 tons. On top of that, the tanker measures 197 feet (60 meters) wide and 94.8 feet (28.9 meters) deep, with a molded draft of 69 feet (21 meters).

The ship is the fourth LNG-fueled very large crude carrier (VLCC) delivered by the Kawasaki Group. As per the firm, the supertanker was built at the Dalian COSCO KHI Ship Engineering (DACKS) shipyard in China. The shipyard is a joint venture between Kawasaki and China COSCO Shipping Corporation.

“This new design greatly reduces wave-making resistance from bow waves during navigation, enabling greater propulsive performance,” Kawasaki officials revealed.

According to Kawasaki, the vessel features a dual-fuel engine. It can operate on both liquefied natural gas (LNG), as well as low-sulfur fuel oil. When running on LNG, the engine could reduce carbon dioxide emissions by about 25 percent to 30 percent compared to conventional heavy-oil engines.

The company also estimates that NOx emissions can be cut by 85 percent, and sulfur oxide emissions (SOx) can be eliminated entirely. This means transporting crude oil over long distances could become less polluting.
