• A numerical scheme is developed to simulate three-dimensional dynamics of a flexible riser. Equations of the riser motion are derived based on ‘Hamilton’s Principle’ and solved using the mode expansion method. This scheme was verified by comparing with results of forced oscillation experiments. Finally, to validate the accuracy of this numerical scheme, the numerical and experimental results were compared and showed good agreements.
