Computation of mean drift forces and wave run-up by higher-order boundary element method Academic Article uri icon


  • A higher-order boundary element method (HOBEM) is used for the reliable computation of the first- and second-order wave loads on arbitrary three-dimensional bodies. The accuracy and efficiency of the present method are demonstrated through the convergence tests as well as comparison with analytic solutions and axisymmetric results. HOBEM is shown to be efficacious especially for the computation of body-surface velocities and velocity potential and its derivatives on the waterline and related integrals. For illustration second-order mean forces and wave run-up on vertical circular cylinders, hemispheres and the stationary ISSC tension leg platform (TLP) are presented.
