Abstract

In the design and construction of floating wind turbine platforms, the use of steel is limited by cost and corrosion concerns. In contrast, concrete materials have gained recognition and popularity due to their affordability and durability. In this paper, a concrete floating platform for a 15 MW wind turbine is designed and compared with the VolturnUS-S. A surrogate model is established to predict the long-term dynamic response of the platform. The results show that the concrete platform in this paper exhibits advantages in hydrodynamic performance and satisfies the relevant requirements of floating wind turbines. Moreover, the cost estimation indicates that the use of concrete can substantially reduce the construction costs.
