“YUMEIRUKA" is an AUV that Japan Agency for Marine-Earth Science and Technology (JAMSTEC) has developed and is operating. A seabed resource exploration is carried out by two-set simultaneous operation with AUV “JINBEI" developed by JAMSTEC. “YUMEIRUKA" towing a sensor cable, and the cable is oscillated by the AUV. The up-and-down oscillation of the sensor has a bad influence on the exploration result. Therefore, in order to perform accurate seabed resource exploration, it is necessary to comprehend the motion of the sensor cable and to optimize it. In this paper, motion simulations of a sensor cable towed by X rudder AUV “YUMEIRUKA" are shown.
