摘　　要： 文章针对穿梭油轮和浮式生产储油轮在并靠作业过程中在不同浪向和不同并靠间距情况下的船体一阶耦合运动及平均漂移力等水动力干扰情况进行了研究。通过研究发现,两船之间水动力干扰情况在不同的波浪频率区域,会出现放大或遮蔽效应,这与单浮体的水动力干扰情况有着很大的不同。计算结果表明由于另一浮体的存在,横荡平均漂移力不仅在大小上和单浮体水动力情况不同,而且在方向上也发生了改变。同时,鉴于横荡方向的运动和受力在动力定位控制系统中是非常重要的,该文可以为装有动力定位系统的穿梭油轮的安全作业,船体水动力干扰情况预测以及工程实践的初步设计提供相关参考和帮助。 In this paper, hydrodynamic interactions were studied between two floating bodies posi-tioned side-by-side as a shuttle tanker-FPSO （floating production, storage and offloading） system. Particular interest is placed on the sway coupled motions and mean drift forces with different sepa-ration distances and various wave directions. The results show that the hydrodynamics between two vessels is obviously distinguished from the single body case with shielding and exaggerating effects. In addition, the sway mean drift forces of multiple body case experience variations in both magnitude and direction compared with the single body case. As the sway motion is one of the most crucial com-ponents considered in DP （dynamic positioning） system, getting a better perspective of the sway mo-tion is beneficial for both the control of a shuttle tanker with DP system and the prediction of behav-ior of the vessels for safe operation. This paper is helpful to both prudent designs in the basic design stage and operations in engineering practice.
