摘　　要：According to the Price-Wu condition at interface between flexible marine structure and surrounding fluid flow, a solution for the 3-D potential flow in time domain around a flexible structure traveling in waves has been expressed with a boundary integral equation. The Green function, which satisfied the linearized free surface condition for the time-dependent problem was employed. A hydroelastic analysis directly in time domain to predict the loads, motions and structural responses of ships at a steady forward speed in a seaway was formulation. The numerical results given by present method were compared with the experimental measurements, and the prediction provided by the 3-D hydroelasticity theory in frequency domain.According to the Price-Wu condition at interface between flexible marine structure and surrounding fluid flow, a solution for the 3-D potential flow in time domain around a flexible structure traveling in waves has been expressed with a boundary integral equation.
