波浪漂移力和漂移力矩的估算对于拖船、拖缆和驳船组成的拖航系统在波浪中的操纵仿真具有重要意义。在倾斜规则波中，测量了弱约束拖船和驳船模型在零Froude数下的波浪漂移力和力矩，并测量了船舶运动的所有六个分量。漂移力矩和漂移力的计算结果与Maruo-Newman理论的计算结果吻合较好，并证实了漂移力和漂移力矩在很宽的波长范围内（包括很短的波长）受船舶运动的显著影响。
The estimation of wave drift forces and moment is important for the manoeuvring simulation in waves of a towing system consisting of tug, towing rope and barge. The wave drift forces and moment acting on the weakly restrained models of a tug and a barge were measured in oblique regular waves at zero Froude number and all six components of ship motion were also measured. The drift moment as well as the drift forces showed good agreement with the calculation by Maruo-Newman's theory and it was confirmed that the drift forces and moment were significantly affected by ship motions for the wide range of wave length including very short wave length.
