Interpretation of nonlinear effects on the dynamic response of a TLP
- Univ. of Texas, Austin, TX (United States)
To determine the nature and importance of various nonlinear effects on the dynamic response of a TLP, a number of parametric studies have been conducted determining the dynamic response of a simplified model to wave and current action. The results of these analyses were then used to compute linear, quadratic and cubic transfer functions, based on Volterra series, to assess the type of nonlinearity which controls the response over the different frequency ranges. The nonlinearities result in the existence of response amplitudes and energy at frequencies which are outside of the range of the excitation frequencies but which correspond to the natural frequencies of the TLP in surge, heave and pitch. They are of different order (quadratic or cubic) over the different frequency ranges (below or above the wave frequency range).
