A new computer code was developed for the prediction of the motions of tow and towed ships and the towing cable tension in oblique regular waves, by extending the code developed in last year. To obtain the validation data for the code, tank tests were conducted at Seakeeping and Maneuvering Basin, Nagasaki R & D center, Mitsubishi Heavy Industries. By systematic change of the wave-maker's parameters, in the measurements, effects of wave period, wave direction and so on were captured. By means of the code newly developed, calculations were made of the motions of tow and towed ships and the towing cable tension in oblique waves, and the results were compared with the tank test results. As a result, it was confirmed that the calculation results roughly agreed with the tank test results. The present method is useful for practical prediction purposes of towing problems in waves.

本文对去年编制的斜向规则波中拖船和被拖船运动及拖缆张力预报程序进行了扩充，编制了一套新的程序。为了获得代码的验证数据，在三菱重工长崎研发中心的耐波性和机动性盆地进行了水槽试验。通过系统地改变造波机的参数，在测量过程中捕捉到了波浪周期、波浪方向等因素的影响。利用新开发的程序计算了斜波中拖体和被拖船舶的运动及拖缆张力，并与水池试验结果进行了比较。结果表明，计算结果与水池试验结果基本一致。本方法对于波浪中拖曳问题的实际预测是有用的。
