YZJ Shipbldg SGD's stock surged 3.09% during intraday trading on Wednesday, driven by positive investor sentiment following the successful commencement of sea trials for the "Xin Yangzi 536," the first newly built ultra-large container ship on the main line of the Yangtze River.

The vessel, constructed by Jiangsu Yangzijiang Shipbuilding Group Co., features methanol dual-fuel propulsion and an integrated energy-saving propulsion system. It is expected to generate $2.641 billion in foreign exchange earnings. The company currently holds orders for 22 such vessels, signaling strong future revenue potential.
