Nonlinear hydrodynamic response of curved singly-connected cables

The nonlinear static and dynamic analyses of three-dimensional, singly-connected cable-body systems are presented in this paper. The governing equations of motion of a cable-body system are derived to form a nonlinear two-point boundary-value problem. The equations of motion describing nonlinear interactions of cable and boundary body are employed as the boundary conditions. A numerical model based on spatial integration and an implicit temporal integration of the time-domain solution is developed to solve the boundary-value problem. Finally, examples are presented to demonstrate the validity and capability of the present model and solution techniques. The model and solution technique are shown to be an…
