Abstract

A single-degree-of-freedom model of a TLP is employed for response. The stochastic frequency domain technique and nonlinear time domain analysis are discussed and compared. The describing function method from control theory, is applied to find linearization coefficient. The superposition method, one of the simulation techniques, is applied to random sea wave, and the response analysis of TLP in time is developed with wave velocity and wave acceleration simulations. Computational methods for both analyses are developed, and the results of stochastic, dynamic response of the TLP, with and without the presence of current are presented and compared.
