Lumped-parameter analysis method for time-domain of ocean cable-body systems

The present paper gives a time domain analysis method for ocean cable body systems and a FORTRAN 77 computer program. The Lumped parameter method is used to model the cuble body system. The cable is taken to be round and extensible with negligible bending rigidity. The Fouth Runge Kutta method is adopted to integrate the motion equation of the system. The paper gives two examples to illustrate the validity of the model. The program can be widely used to analyze moring lines, towing and ROV umbilical cables with series connected ocean cable body systems in the primary design stage.
