Offshore wind farm developments are growing rapidly and entering new markets globally. The majority of offshore wind turbines (OWTs) are supported by monopiles, which are typically impact-driven into the seabed. Alternative installation and foundation solutions include vibro-driven piles and suction buckets. Irrespective of the selected solution, successful installation is critical to the in-service performance of the foundation. This requires the mechanisms to be understood in detail. The installation process itself has the potential to significantly change the soil state. OWTs are dynamically sensitive systems, with the foundation stiffness contributing to the overall response. OWTs are also sensitive to out-of-verticality, requiring the accumulation of displacements to be predicted. This presentation discusses recent research of monopile and suction bucket installation, the changes of soil state resulting from the installation process and the in-service performance of these OWT foundations.
