Abstract:This study has focused on developing numerical procedures for the static and dynamic nonlinear analysis of mooring lines A geometrically nonlinear finite element method using isoparametric cable element with two nodes is briefly presented on the basis of the total Lagrangian formulation The static and dynamic equilibrium equations of mooring lines are established An incremental-iterative method is used to determine the initial static equilibrium state of cable systems under the action of self weights, buoyancy and current Also the Newmark method is used for dynamic nonlinear analysis of ocean cables Numerical examples are presented to validate the present numerical method, and examine the effect of various parameters
