Abstract

This paper provides an introduction to the geotechnical design of Offshore Wind Turbine (OWT) foundations using the Finite Element Method (FEM). Procedures for incorporating the FEM in the design process are proposed under particular consideration of the practical application to commercial projects, where foundation design is done in a serial production. The proposed procedures allow to streamline the design process and enable to optimize the foundation geometries of OWTs under given time and resource constraints of typical Offshore Wind Farm (OWF) development projects. Advantages and disadvantages are discussed using the example of the design of Monopiles and Suction Caissons.
