Electricity has a social value as well as a monetary one, which is constantly increasing. It is a strategic asset that has become indispensable for years. For this reason, the energy production sector is fundamental, as is sustainable production, given the ongoing climate change. The aim of this study is to optimize the spatial arrangement of an off-shore floating wind turbine array in such a way as to increase the efficiency and maximize the energy yield in relation to the cost of the initial investment. The problem was tackled by combining two different analyses: a fluid dynamics one and an optimization one.
