Chinese shipbuilder Dajin Heavy Industries, a wholly-owned subsidiary of Bestway Marine and Energy Technology, and the China Railway Construction Bridge Engineering Bureau Group have entered into an agreement for the construction of a 156-metre dynamically positioned pile driving vessel.
Construction of the vessel will be funded by the China Railway Construction Bridge Engineering Bureau Group. Design work will be undertaken by Shanghai Jiahao Marine Engineering Research and Design.
The vessel will be specifically designed for the Salvador Cross-Sea Bridge project in Brazil. It will also be one of the first Chinese-built piling vessels to be fitted with a DP3 dynamic positioning system.
The vessel's pile frame height will reach 156 metres whilst its operating water depth will exceed 70 metres. The piling positioning accuracy will reach the centimetre level with coordinated control via dual-frequency RTK GPS and a dual-mode positioning system.
Although it will initially support bridge construction projects, the piling vessel may also be employed for offshore wind farm construction.
