User's Manual for the Buoy-Cable-Body Computer Program CABUOY

Abstract

CABUOY is a Fortran IV program. The program solves for the two- dimensional dynamic motions of a cable suspended system deployed in an ocean environment. Intended as an engineering tool, the program can model any combination of cable segments and attached bodies configured as either a towed, moored, or free drifting system. The positions of all bodies and the resultant cable tensions are calculated as functions of time. This time domain approach, though more costly in terms of execution time than the more common frequency domain method, was chosen because it allows for the solution of transient motions which may induce high tension loads in the cable. The program employs a finite element analysis to model the cable-body system. The resultant differential equations are integrated using a Kutta-Merson routine which automatically reduces the integration time step until specified error criteria are met.
