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.
