Typical comparisons with results from towing tank experiments are shown above. A number of alternative designs can easily be assessed and compared for seakeeping performance. Seakeeper is able to compute the heave and pitch response over a complete frequency range in a matter of seconds on a Pentium II computer. Comparisons of different vessels can be made by examining the RAOs or by computing the significant motions and accelerations for a specified sea spectrum. All data generated can be graphed in Seakeeper or exported for further analysis.
Designers now have access to powerful numerical techniques for predicting vessel motions.
Seakeeper Features Direct integration of surface model. Calculation of vessel response amplitude operators. Calculation of added resistance response and integration of added resistance for specified sea spectrum. Integration of significant vessel motions for specified sea spectrum. Graphical and tabular presentation of all data generated by the analysis.
