CHINA-JIANGSU-QIDONG-DREDGING VESSEL (CN)

Chinese-built dredging vessel Tian Kun Hao, the largest of its kind in Asia, departs a port for its first sea trial, in Qidong, east China's Jiangsu Province, June 8, 2018. The 140-meter-long vessel, with the designed capacity to dredge 6,000 cubic meters per hour, can dig as deep as 35 meters under the sea floor. The three-day sea trial will test its power system, speed and anchoring, and check other navigational aids such as radar and gyrocompass. After being tested, the vessel will sail back to the shipyard and is expected to be delivered in August. (Xinhua/Li Xiang)
