The dynamic motion characteristics of the cable systems are of great interest. Dynamic behavior of thesystem may directly influence its safety in wind, wave and current. In general, the diameters of the cable are small,model tests of the entire system are often difficulty, therefore, numerical modeling is an effective solution. A typicalsonobuoy mooring system consists of three components: surface buoy at the upper end; A cable whose properties mayvary along its length; and intermediate bodies along the cable, including possibility of a body at the lower end.This paper analyzes in time domain the two-dimensional dynamic behavior of general ocean cable systemsconsisting of a surface buoy, connecting cable, and intermediate bodies. The equations which model the motions ofthe surface waves, and the various components of the cable system are presented. A sample problem is given.
