Abstract

A foundation concept that uses natural forces to install and mobilize the capacity of the foundation is described. Preliminary research and development on an implementation of this concept using a wing-shaped anchor for floating offshore wind turbines has included conducting model tests in clays and sands in the laboratory and developing simplified predictive models. This work indicates that the concept may be feasible, with the ability to embed the anchor several anchor widths during gravity free-fall and several more anchor widths during loading in service. Also, plasticity-based predictive models are able to capture its behavior during model tests.
