Framework for evaluating scour risk and optimising scour mitigation
Framework for evaluating scour risk and optimising scour mitigation
Scour poses a significant risk to seabed foundations. Common practice is to design scour protection to ensure protection against extreme metocean events such as 50-year storms. This may have been acceptable for oil and gas projects but, with the increasing size of offshore wind projects, this could result in excessive costs associated with the transportation and installation of scour protection. This paper aims to provide a framework to evaluate the main factors influencing scour risk such as; soil conditions including surface soils and the depth to potentially scour resistant soils, the metocean conditions which could result in scour, the potential rate of scour, as well as understanding the potential consequences of scour on foundation performance. This understanding will allow the specification of appropriate scour mitigation.
