EFFECTS OF CURRENT ON DYNAMIC RESPONSE OF OFFSHORE PLATFORMS

The stochastic dynamic responses of offshore platforms, with and without the presence of current, are studied and discussed. The formulation derived in the paper can be used to determine the statistics of platform response with proper consideration of the nonlinear effect caused by current. The phenomenon of wave-current interactions is known to change wave characteristics; its effect on structural responses is also examined. Five deepwater platforms are analyzed under different wind wave and current loading conditions. Numerical results showing the effect of current, the contribution of current when the wind waves become stronger, and the effect of wave-current interactions on the dynamic response are presented.
