Stochastic Response of Tension Leg Platform to Wave and Current Forces

The linear analysis in the frequency domain is presented for the surge motion of a tension leg platform (TLP) in the case of random waves only and random waves with constant current. A single-degree-of-freedom model of a TLP is employed for response. The superposition method is applied to random sea wave. Wave-induced forces are calculated using the modified of Morison equation, which takes into account relative motion
