A STUDY OF CAPSIZING MOTIONS IN REGULAR SEAS AT THE TOWING TANK OF THE UNIVERSITY OF CALIFORNIA

Several aspects of the experimental techniques and procedures developed for the study of severe ship motions and capsizing at the towing tank of the University of California are presented. The procedure for preparing the model correctly for capsizing tests is discussed in detail including both the arrangements of deck and towing apparatus that did not work as well as those that did. The necessary calibration and daily routines for expeditous work are also discussed along with the inclining abd balancing procedures for setting the metacentric height and radius of gyration. Some preliminary results of tests in regular waves and wave groups are presented with a brief discussion and some areas to pursue in future work. Finally, a brief summary of a time domain single degree of freedom numerical integration program to simulate rolling motion of a ship in regular seas is presented along with some comparison plots of results presented in the discussion section.
