HEAVE AND ROLL RESPONSE OF FREE FLOATING BODIES OF CYLINDRICAL SHAPE

The following report describes a computer solution to help predict the heave and roll response of free floating bodies of cylindrical shape when excited by random seas with known spectra. The basic concepts of harmonic analysis and statistics used in the method are first briefly reviewed. The report then presents a detailed derivation of the linear heave and roll response amplitude operators that is the expressions of the vertical and angular displacements produced by a simple harmonic wave of one foot amplitude. The second part of the report reviews the computation procedure and the program's logic. It gives a detailed set of instructions for the program users, reviews the program's capabilities and limitations, and presents three case studies. The heave and roll response programs are written for use with XEROX SIGMA 7 computers. Program listings are given in the appendix. (Author)
