Over recent years the offshore wind turbines are becoming more feasible solution to the energy problem, which is
crucial for Egypt. In this article a three floating support structure, tension leg platform types (TLP), for 5-MW wind
turbine have been considered. The dynamic behavior of a triangular, square, and pentagon TLP configurations under multidirectional
regular and random waves have been investigated. The environmental loads have been considered according to
the Egyptian Metrological Authority records in northern Red sea zone. The dynamic analysis were carried out using
ANSYS-AQWA a finite element analysis software, FAST a wind turbine dynamic software, and MATLAB software.
Investigation results give a better understanding of dynamical behavior and stability of the floating wind turbines. Results
include time history, Power Spectrum densities (PSD’s), and plan stability for all configurations.
