1G scaled model of impact driving and lateral behavior of offshore monopiles
1G scaled model of impact driving and lateral behavior of offshore monopiles
To address the need for comprehensive understanding of impact hammering in monopile installation in the offshore industry, this study employs a 1G experimental setup that represents the driving and the lateral loading of an offshore monopile at a reduced scale. The setup includes piles of 6 cm and 11 cm diameter, equipped with fiber optics, an impact hammering system, and a lateral loading system. The installation phase and subsequent lateral loading are meticulously recorded using sensor technology. In addition, numerical models are employed to study the dynamic behavior of the 1g scale test and are used to further optimize the test setup. The study's findings encompass force-displacement under lateral monotonic loading. Also, the study emphasizes how different driving parameters affect the installation process and the lateral loading response.
