Earthquake design of offshore platforms is one of the main parts in offshore platforms design on which seismic soil pile structure interaction could be the main concern. In seismically active areas, it is often necessary to perform a dynamic analysis that accounts for nonlinear pile soil structure interaction effects. Based on a previously developed numerical BNWF-FE model for nonlinear seismic response of offshore platforms, in this paper, sensitivity of seismic response of an existing sample offshore platform to different earthquake events (with different duration and different frequency contents) together with the sensitivity of the results to the model main parameters are investigated.
