Simulation of joint wind and wave loading time histories

To harness vast amounts of energy with offshore wind turbines, it is necessary to analyze the dynamics of these structures. This requires simulation of the forces that these tall, flexible and slender structures are subjected to. Since sea waves are caused by wind blowing for a sufficiently long time, the state of the sea is related to wind parameters and the possibility of correlating wind and wave loading conditions on structures exists. Traditionally the literature available for wind and wave loadings has isolated the respective loadings on the offshore structures, possibly neglecting combined modes that may induce large structural vibrations in the process. Time simulation histories of joint wind and wave loading are not commonly available in literature. The Harris spectrum for wind loading is combined with the JONSWAP wave spectrum to formulate correlated wind and wave loadings. The simulation results for the time histories of wind and wave loading are presented and concluded upon
