China's first 10,000-ton intelligent oceangoing vessel powered entirely by electricity has entered sea trials in Jiangxi province. It is the largest ship of its type in the world.

The 740-twenty-foot-equivalent-unit (TEU) pure electric open-top container ship, Ningyuan Diankun, built by Jiangxi Jiangxin Shipbuilding, departed from its dock in Hukou county of Jiujiang city on Feb 1 after completing outfitting and mooring tests.
