DYNAMIC ANALYSIS OF CABLE WITH AN INTERMEDIATE SUBMERGED BUOY FOR OFFSHORE APPLICATIONS

In this paper the nonlinear static and dynamic equations of a cable with an intermediate buoy are derived, and small motions of the mooring line around its static configuration are simulated. The analysis of a mooring line with and attached buoy is necessary to assess the safety of the cable-buoy system in deeper water. In the comparison of the dynamic tensions at the right side and the left side of the attachment point, it was found that there was little difference between the dynamic tensions along the cable and was uniform as in the case of a cable without buoy. However, the effect of the buoy on the maximum dynamic tension seemed severe, since the extreme values of the steady-state dynamic tensions increased more than three times relative to those of the cable without a buoy.
