These predictions were made for the WAGB design, using a modified three-degree-of-freedom linear roll theory which recognizes the nonlinear roll damping moment, in conjunction with the David W. Taylor Naval Ship Research and Development Center Antiroll Tank Facility. The antiroll tank investigation considered various water depths and tank dimensions. The results indicate the installation of the antiroll tank will assure a significant reduction in the RMS roll during the ship transits. (Author) 收起
