The Nantong Chuanqi 425, an ultra-large container vessel developed, designed, and constructed entirely in China, recently completed its trial voyage from the Yangtze River. This achievement marks a major breakthrough in China's shipbuilding industry in its pursuit of high-end, intelligent maritime engineering and reflects significant progress in core technological innovation.

Dubbed a “colossus of the seas,” the Nantong Chuanqi 425 stretches nearly 367 meters in length, with a beam of 51 meters and a deadweight tonnage of approximately 160,000 tons. With a capacity of up to 16,828 TEUs (twenty-foot equivalent units), it ranks among the largest container ships capable of transiting the new Panama Canal locks. From shore, the vessel appears as nothing less than a moving fortress of steel.

Equipped with a suite of advanced energy-saving technologies—including a next-generation, energy-efficient engine and a low-resistance hull design—the ship achieves world-leading performance in energy consumption per container. These innovations significantly enhance China’s competitiveness in the global market for designing and building large-scale green vessels.
