An integrated ship for the transportation and installation of immersed tubes is seen during a “super drill” recently. The ship, the first one of its kind in the world, simulated “handling” immersed tubes on a sea area extending 6.5 kilometers. The immersed tubes will be used for the construction of the world-class Shenzhen-Zhongshan Corridor sea channel. Spanning 24 kilometers, the Shenzhen-Zhongshan link is a complex bridge, island and tunnel project modeled after the Hong Kong-Zhuhai-Macao Bridge. Upon completion in 2024, it will be an important passage between eastern and western cities of the Pearl River Delta. Yao Jiali |
