This paper presents generic Monte Carlo-based approach, based on satellite wave data, for extreme response prediction of offshore structures, particularly Jacket type. An operating Jacket in Bohai bay was taken as an example to demonstrate proposed methodology. Satellite-based global wave statistics was used to obtain wave scatter diagram in the area of interest. Effects of second-order waves and sea current were taken into account. The detailed finite element Analysis System (ANSYS) model was employed to study non-linear Jacket dynamics, subject to hydrodynamic wave loads. Stresses in the most critical structural members were extracted and extreme value study was carried out. Proper extrapolation technique was applied to predict stresses with 10–50 year return periods, which is of practical interest for the design and operation of offshore structures.
