N2 - Liquefaction of soil resulting from earthquakes can lead to the failure of structures due to the significant reduction of the foundation bearing capacity. Offshore wind foundations are the type of structures that may be susceptible to earthquake damage. Gravity and Mono-pile foundations are typically adopted for offshore wind turbines in past projects. This study is focused on a new type of group-pile foundation with four legs. A group of centrifuge tests was performed to evaluate the seismic stability of this type of foundation. Acceleration, pore water pressure, settlement, and lateral displacement were recorded to analyze the seismic response of both the upper structure and foundation. Comparisons with test data of other types of foundations were made. Data analysis and comparison shows that this type of foundation has some advantages in improving seismic stability.
