  • [Qiongzhou Strait transportation new energy vehicle ship successfully docked]
  • On the afternoon of October 8th, under the on-site escort of the Guangdong Zhanjiang Maritime Bureau's "Haixun 0927" ship, the first flatbed cargo ship dedicated to the transportation of new energy vehicles in the Qiongzhou Strait, the "Green Source No. 1" ship, slowly entered the Xuwen Hai'an New Port, marking the successful trial operation of the ship's roll on/roll off transport route in the Qiongzhou Strait. It is reported that the deck cargo ship "Green Source No.1" has a total tonnage of 6731, a net tonnage of 3769, a length of 125.8 meters, and a width of 28 meters. The ship adopts a single-layer deck design, which can carry more than 160 new energy vehicles on a single voyage under full load conditions. The parking capacity is about 60% higher than that of existing passenger and roll on/roll off transport ships. The ship is planned to be deployed on the route from Hai'an New Port in Zhanjiang to Xiuying Port in Haikou. After being put into operation, it will add a new mode of sea transportation for new energy vehicles in the Qiongzhou Strait and effectively alleviate the tense situation of insufficient capacity for new energy vehicle transportation during the peak period of cross sea vehicle transportation in the Qiongzhou Strait.
