摘　　要：为了研究多浮体水动力相互作用下的波浪载荷和船体响应,针对旁靠系泊的穿梭油船与FPSO进行模拟计算。其中二阶波浪力采用近场方法求解。计算分析发现,由于屏蔽效应的影响,穿梭油船上的波浪绕射力受水动力相互作用的影响较大,平均二阶波浪漂移力在波频的高频段受水动力相互作用影响显著,在低频段几乎不受影响,而附加质量和辐射阻尼以及船体响应的RAO受影响则较小。另外,随着穿梭油船与FPSO相对距离的小范围变化,水动力相互作用的影响并没有太大的差别。A series of calculations were carried out to investigate the hydrodynamic loads and responses of FPSO and shuttle tanker moored in side-by-side,in which the steady wave drift force was calculated based on the near field.Because of the shielding effect,it was found that the diffraction force on the shuttle tanker is significantly affected by the hydrodynamic interaction,and the steady wave drift force in the high wave frequencies has the same regular as the diffraction force.However the steady wave drift force in the low wave frequencies is slightly affected by the hydrodynamic interaction,the added mass,radiation damping,and vessel＇s RAOS are only affected marginally.In addition,the effect of the hydrodynamic interaction does not change greatly as the relative distance between the FPSO and shuttle tanker increases.
