The Tension Leg Platform (TLP) uses the buoyancy of its floater to tension mooring lines between the floater and the anchor points in order to stay stable. In order to compute the system response of tension leg platform wind turbines (TLPWTs), it is important to accurately capture the hydrodynamic loading not only at the wave frequency, but also in the low (difference) and high (sum) frequency ranges. ; writing—review & editing, N.A. 1 DTU Wind Energy, Nils Koppels All e, Building 403, DK-2800 Kgs.
