Among renewable energy generation technologies, wind energy is considered one of the most promising and energy-efficient. Therefore, its proper study is essential. This paper analyzes the preliminary stability of a semi-submersible platform for a wind turbine. Peruvian sea conditions are quite favorable for implementation, considering the average maximum wave height of 1.61 m near the coast of Chancay. Where wind speeds are 9 m/s and energy densities are 700 W/m².

One of the most important stability aspects is determining the natural frequencies of the floating structure. To achieve this, experimental tests will be conducted using a reduced-scale 1/40 platform model with a 5 MW power output and free decay tests to obtain the damping characteristics of the floating system. This information will validate numerical simulations using computational fluid dynamics (CFD) to determine free decay in roll, heave, and surge conditions, and tests under wave conditions in regular sea conditions for the free and moored platforms.
