Nonlinear Analysis of Seabed Interaction and Mooring Cable Dynamics with A Finite Element Approach
نویسندگان
چکیده
In this paper, an efficient two-dimensional finite element model for a mooring cable and seabed interaction is built while geometric shape and tensions of the cable are computed in time domain. In the model, a hybrid beam element is employed to simulate the mooring cable with the seabed simulated by different soil constitutive models. When the elastic and elastic-plastic soil constitutive models are used for computation, the mooring cable stresses and offsets at fairlead point are also compared accounting for friction effect between cable and seabed. Both transversal and longitudinal behaviors are studied at different water depths.

Abstract: In this study, a deterministic approach for the dynamic analysis of a multi-component mooring line was formulated. The floater motion responses were considered as the mooring line upper boundary conditions while the anchored point was considered as pinned. Lumped parameter approach was adopted for the mooring line modelling. The forces considered were the submerged weights of mooring/...
