Abstract

Experimental investegations have been developed to model the performance of floating offshore wind turbines (FOWT) under wave forces in order to design and optimize them. A comparsion of two types of FOWT,Spar and TLP, were disscuesd experimentally.
To guarantee accurate results for the responses comparison, two experimental models were created. First, a simulation of tension leg platform wind turbine by 1/100 scale factor. Secondly, a 1/300 scale model of a 3-leg catenary mooring spar buoy platform model.To simulate real-world conditions, irregular wave states were generated in the Benha Faculty of Engineering laboratory where the models experiments were carried out. Our findings demonstrate that The models responds well in the surge directions, For spar model, in comparison to the surge, pitch, and heave responses, the sway, roll, and yaw responses are very small, For TLP model, in comparison to the surge, sway, and roll responses, the heave, pitch, and yaw responses are very small.
