In the design of an atomic power plant to be installed in a nuclear ship, full caution must be paid to the acceleration given rise to by its oscillation. For studies of magnitude of the acceleration, frequency dlstribution, etc., theoretical calculations were combined with model experiments. This study was undertaken to obtain the maximum value of acceleration due to oscillation and other causes from the survey results on eight voyages of three high-speed cargo ships and one supertanker covering different oceans and seasons in 1959 and 60. The maximum value of acceleration caused by the oscillation in the high-speed cargo ships was estimated at 1.36 g at fore end, 0.45 g at midship, and 1.03 g at aft and in the vertical direction and 0.39 g in the horizontal direction. Fairly large high frequency impact acceleration usually arose sectionally due to whipping in case of the light draft navigation of a high- speed cargo ship in high-speed service. For the general construction, this external force may be ignored, but, for the design of the control and instrumentation system of the nuclear ship, the characteristics of response of the machinery and instruments must be considered.
