Abstract
Egypt is one of the best places in the world to find wind power. With wind speeds at average 8.5 to 10 m/sec, Egypt is at
the forefront in the region in terms of wind power. In this investigation a Spar-Type offshore structure equipped with 5MW
wind turbine have been considered. The dynamic motion responses are critical for designing the substructures of Spar-
Type wind turbines. All environmental loads from waves and wind have been considered in this investigation. The
available data for the Gulf of Suez area from the Egyptian Meteorological Authority was used to determine the
environmental loads. For the dynamic study, the analysis software ANSYS-AQWA was used to determine out the
hydrodynamic properties, FAST simulation software for wind turbine, and MATLAB software for the spectral analysis. The
results of the investigation help to better understand the stability and dynamic response of Spar-Type wind turbines. Time
history, Power Spectrum Density, and phase plan are included in the results.
