Spar Platform Project with Pressurized Tank for Offshore Wind Turbines

The growing demand for energy and the concern about global warming spur the search for renewable energy. One of the most developed green energies today is wind energy. The development of wind energy began with land turbines. However, concerns about visual and sound impacts, as well as difficulties in finding appropriate spaces for their installation, have driven the transition to shallow waters with fixed structures on the ocean floor.

Currently, a transition to deep water with floating structures can be observed. This can be explained by the better quality of the wind at a considerable distance from the coast as well as the limitation related to the depth of the water for the installation of fixed structures.

Thus, this work aims to obtain the behavior of a wind turbine supported by a Spar-type floating platform in two different regions near the coast of Brazil to evaluate its feasibility. The energy output of the turbine and the hydrodynamic behavior of the platform are considered in this comparison. All simulations are done with the OpenFAST spruce code, in which the hydrodynamic and aerodynamic effects on the structure are considered. The hydrodynamic behavior modeling was performed using the Mamit software. Wind information as well as wave information is determined according to the region studied
