Bucket foundations for offshore wind turbines provide an attractive alternative to piles, since they introduce potential for improved fabrication, transport and installation efficiency. This presentation discusses the potential for the use of vibratory methods to install the buckets. Vibratory driving has a number of advantages: installation time is extremely rapid, driving stresses are relatively low, and it is quieter than impact hammers that are often used for monopile installation. Although vibratory installation is particularly well suited to sandy soils, it has a demonstrated track record for successful installation in stiff clays. The capabilities for vibratory driving in a wide variety of soil types renders this method of installation particularly attractive for the heterogeneous soil conditions common to many potential wind farm sites. In contrast to impact hammers, multiple synchronously vibratory hammers can be attached to a single monopile or bucket. Thus, there are no strict limitations on the foundation size for which vibratory installation is possible, and bucket with diameters in excess of 20 meters have been successfully installed. Installation models, which are currently being developed in a project sponsored by the National Offshore Wind Research and Development Consortium, will be discussed in this presentation. Other issues relevant to vibratory installation of bucket foundations, such as the potential for reduced frictional resistance at the bucket wall-soil interface, and its implications on required bucket dimensions for the current generation of 15-MW wind turbines will also be discussed.
