Abstract

HAWCStab2 is a linear frequency domain aeroelastic tool, developed by DTU Wind Energy, suitable for frequency and stability analysis of horizontal axis 3 bladed wind turbines. This tool has now been extended to also handle complex offshore foundation types, such as jacket structures and floating structures with mooring lines, using super elements calculated by the nonlinear time domain aero-elastic code HAWC2. In this work the NREL 5MW Offshore RWT mounted on a jacket support structure is investigated using both HAWC2 and HAWCStab2.
