Lateral response of vibratory installed monopiles: A scaled lab investigation

Abstract

The installation of monopiles for offshore wind turbines via vibratory methods presents an alternative to conventional impact-hammering, offering reduced noise emissions. However, understanding the influence of vibratory installation on e.g. lateral pile response remains largely unknown compared to impact-driving. This talk presents findings from laboratory-scale tests investigating the lateral behavior of monopiles subjected to various installation parameters, focusing on sand density and installation methods. The results provide insights into the differences in lateral response between vibratory and impact-driven installations.
