AN EMPIRICAL DESIGN FORMULA OF A SHARED PILE ANCHOR FOR A FLOATING OFFSHORE WIND TURBINE

Abstract

In order to widely promote the large-scale floating offshore wind farm among the private sector, it is the deciding factor how much economical installation method can be developed with regard to the installation cost which accounts for a large proportion in investment costs. In this paper a preliminary design of a shared pile anchor was made based on the result of dynamic mooring simulation and it was found that a simple empirical design formula of an optimum pile specification can be established against N-value, which is useful for preliminary estimation of the installation cost.
