Design and analysis of a box floater with damping plates for floating wind turbine platform

Abstract

In the present study, a numerical and experimental study is conducted for a floating wind tower substructure of 5MW capacity. The design targets are cost effective, smaller draft than SPAR, simple to construct and install. The basic idea for shape design comes from the truss-spar which utilizes a large heaving plate for enhancing global performance. A 9-node HOBEM was applied for numerical parametric study because of its accuracy especially for sharp-edged shapes. A preliminary model test was conducted for verification of the numerical design. The numerical and model tests results were compared with same class spar type design. Copyright ？ 2012 by the International Society of Offshore and Polar Engineers (ISOPE).
