Abstract : In the course of a continuing study of the internal fluid dynamics of free-surface ship-roll stabilization tanks, a lack was noted of systematic experimental information combining the effects of tank distance from center of rotation, excitation amplitude and fluid depth for either the 'rectangular' type tank or the 'H' type. The purpose of the report is to present data obtained in an experimental study aimed at supplying a portion of this missing systematic information for two typical tank geometries. Those data which could be compared with previously obtained data appear in quantitative agreement within experimental accuracy. The data also appear to be qualitatively self-consistent and suitable for use in verification of improved analytical representations of the tank fluid dynamics. (Author)
