A 24,188 twenty-foot equivalent unit (TEU) ultra-large container ship was launched in Nantong City, located in east China's Jiangsu Province on Wednesday.

With a length of 399.99 meters, a width of 61.3 meters, a height of 33.2 meters, and a maximum stacking layer equivalent to the height of a 22-story building, the vessel is large enough to accommodate 24,188 standard containers.

Capable of carrying a maximum of 228,000 tonnes of cargo, the ship is currently one of the largest in the world and carries some of the heaviest containers, earning it the nickname "castle on the sea."

It is the fourth ship in a series of six built by Nantong COSCO Khi Ship Engineering Co., Ltd, a shipyard based in Nantong, featuring advanced safety, energy-saving technologies, environmental protection measures, high efficiency, economic benefits, and a high level of intelligence.
