| Research Abstract |
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.
