Second-order sum-frequency oscillations of tension-leg platforms: prediction and measurement
Abstract A series of model tests has been performed in regular waves to measure secondorder sum-frequency oscillations and tether forces of tension-leg platforms (TLPs). These test results are used to validate the predictions based on a recently developed second-order diffraction theory for general three-dimensional bodies. It is found that the vertical-plane motions and resulting tether forces of the TLPs include second-order sum-frequency resonant components which are comparable in magnitude with first-order wave-frequency responses. The correlation between predicted and measured results is satisfactory, overall confirming the validity of the theoretical predictions.
