World’s largest dual-fuel methanol container ship moves to fitting dock

April 23, 2026 |

In China, the world’s largest methanol dual-fuel container ship berthed at a finishing dock in Nantong on April 21 under maritime authority escort, as the 399-meter vessel capable of carrying 24,168 twenty-foot equivalent units neared the end of its outfitting phase ahead of sea trials planned for June.

The ship, designated Nantong Kawasaki 456, was developed and built entirely by Nantong COSCO KHI Ship Engineering and weighs in at 225,000 deadweight tons. It runs on a methanol dual-fuel propulsion system paired with a large permanent magnet shaft generator, giving it both low emissions and high efficiency. Maritime authorities temporarily restricted traffic on the port, waterway and ferry routes during the move, coordinating a fleet of five patrol boats, four tugboats and two guard vessels to manage the operation safely.
