Generating Ship Motion Time Histories

Abstract

PAT-86 is a suite of seakeeping computer programs which may be used for predicting motion spectra of ships in waves. This technical memorandum describes a method of generating time histories from these motion spectra. A computer program which generates time histories has been written and is listed in the Appendix. Comparisons of the motion spectra from PAT-86 are made with the spectra of the generated time histories. These comparison are shown to be satisfactory.
