TYPES OF FLOATING PLATFORMS FOR WIND TURBINESįloating offshore wind energy is based on floating platforms for wind turbines. This is where the different types of floating platforms for wind turbines come into play, which we will review below. In addition to floating, wind turbines must produce as much energy as possible, and to do this it is essential that they remain stable, minimising any movement and ensuring that they operate under optimum conditions. From there, the process is the usual one: the force of the wind turns the blades and the wind turbine converts the kinetic energy into electricity, which is transported by underwater cables to an offshore substation and from there to an onshore substation on the coast and finally to homes via the power lines. Some call it a "floating foundation", but this term is not correct because floating platforms are not founded on the seabed, but are anchored and moored.įloating wind farms are made up of wind turbines that are placed on floating structures and stabilised by moorings and anchors, and by the way the design of the structure distributes the masses and weights. To find out how floating offshore wind energy works, we must first answer the following question: Why do wind turbines float in the sea as structures 120 metres high and weighing thousands of tons? The solution was given by Archimedes 2,300 years ago: "a body totally or partially submerged in water experiences a vertical upward thrust equal to the weight of the water dislodged".Ī floating offshore wind platform (FOWP) is the concrete, steel or hybrid substructure on which the wind turbine is installed, providing it with buoyancy and stability. HOW DOES FLOATING OFFSHORE WIND ENERGY WORKS In addition, as noted above, they can take advantage of the strong winds blowing in the deeper areas, which improves energy efficiency. It thus overcomes a stumbling block to providing clean, inexhaustible and non-polluting energy for a more sustainable planet.Īmong the advantages of floating offshore wind are the potentially low environmental impact and the ease of manufacture and installation, as the floating turbines and platforms can be built and assembled on land and then towed to the offshore installation site. Basically, it opens the door to sites further offshore by allowing the deployment of wind turbines in larger and deeper offshore areas with higher wind potential. Its high potential and strategic added value, both at a socioeconomic and environmental level, make it one of the renewable sources that will play a crucial role in the decarbonisation process.įloating offshore wind, based on floating structures rather than fixed structures, offers new opportunities and alternatives. WHAT IS FLOATING OFFSHORE WIND ENERGYįirst of all, let us define what offshore wind energy is: it is a source of clean and renewable energy obtained by harnessing the power of the wind offshore, where it reaches a higher and more constant speed due to the lack of barriers. Advances invite optimism and, in this article, we will focus on one of them: floating offshore wind energy, one of the most promising derivatives. To achieve this, renewable energies will play a fundamental role and the effort to innovate in the sector is particularly intense. The main challenge facing humanity today is to achieve a green and sustainable planet.
