Abstract: An analysis method on shipment and offshore transportation of Hong Kong Zhuhai Macao Bridge piers is studied and the reasonable transportation program is designed in this paper. According to the huge structure′s weight and scale， the shipment scheme is developed. A 3D mass model of bridge pier and transportation system model including bridge pier and barge is established with hydrodynamic software. By calculating wave loads on the barge based on potential flow theory， the stability and motion response analysis of the barge pier model is carried out， and the stability of bridge pier during offshore transportation is examined. The calculated results show that without partial reinforcement the stability requirement of bridge pier is difficult to meet under the action of transverse wave， and that transportation requirements are satisfied in the wave angle less than 45 degrees. The stability of the bridge pier during offshore transportation under all wave directions is satisfied through partial reinforcement with lateral buttress and wire rope.
