Goal: Optimize weight, stiffness and strength of a piling template by means of a parametric study. The piling template was used for the installation of foundations for offshore wind turbines. Two situations were analyzed: behavior of the piling template during pile driving and during template handling.
Result: The corners of the piling frame were modeled in Solid Edge. The lattices were modeled in Femap. The Femap model also included the seabed. The sea bed stiffness was made such that the resulting stiffness closely corresponds with the actual stiffness of the seabed in the offshore location. Many parameters were varied to come to an optimum combination of weight, stiffness and strength.
