ind farms are a clean, sustainable and independent way to produce electricity on land, and offshore wind farms are
becoming increasingly more common. This second type actually produces energy more efficiently, but the current technology for implementing them involves higher installation and maintenance costs (Fig. 1). Also, when there
are no offshore locations far enough from the coast at the right water depth (less than 60 metres) where the wind turbine can be anchored directly to the seabed, more expensive systems must be used such as mooring, anchoring and floating structures. To provide a solution to these problems, AIMPLAS, the Plastics Technology Centre, is participating in the FLOTANT project, which aims to develop a solution for installing marine wind farms in water depths of 100 to 600 metres, with installation and maintenance costs that are 55% to 60% lower than at present. FLOTANT, which began in April 2019, is framed within the Figure 1 - Offshore wind farms actually produce energy more efficiently, but the current technology involves higher installation and maintenance costs.

system made of high-performance polymers that will reduce platform movements (Fig. 2). This solution will consist of a plastic-concrete hybrid floating system, dynamic lightweight wiring and a high-performance power export system. The project has chosen three different environments to install three prototypes: dynamic testing equipment for marine components used in the anchoring and power export systems, a tank that simulates marine conditions for the prototype of the comprehensive system, and the Port of Taliarte (Gran Canaria) for characterization of the new polymeric materials under real marine conditions. AIMPLAS role in the project is mainly to develop and optimize the anchoring, wiring and floatation system through the development of thermoplastic and thermoset materials with antifouling and antibite properties (Fig. 3). The result is expected to reduce the cost of producing this type of energy from €107 per MWh in 2018 to €85-€95 per MWh by 2030. This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant
