The Wave-Load Analysis of the Offshore Wind Power Installation Vessel Based on Frequency-Domain Methods

Abstract:

The wave force spectrum expressed in terms of Morison's equation was deduced by ocean wave theory and spectral analysis theory, and the spectral analysis of wave force were analyzed with the finite element method which was applied to the leg of the offshore wind power installation vessel, the natural frequencies and the vibration model were accomplished with boundary conditions. The dynamic response of the leg were studied in different conditions, it can be concluded that the wave force of the leg is only related with geometric shape and working depth of truss legs.
