A further study on the scour around the monopile foundation of offshore wind turbines

Foundation scour has long been a concern in the offshore wind industry as it poses great threat to safety of turbines (OWTs). However, current understanding this issue is still insufficient. This because many farm factors and their coupling effect on have not fully investigated. Therefore, two phases experimental studies are conducted paper investigate how monopile vibration, water flow, intermittent operation OWTs work together affect around foundation. The research results shown that absence vibration can also create ‘scour pits’ while causing soil densification. large-amplitude flow will exacerbate scour, small-amplitude retard scour. amplitude greater influence than frequency. In addition, sequence was found significant but despite sequence, repeated application removal which represents OWTs, lead severe foundation
