Wind energy has been in use since the end of the 19th century. In Denmark, for example,
there was the great development of wind power from the manufacture of the first turbines
by small agricultural equipment companies. Around 1980, countries such as Germany
and the USA through incentive policies, triggered investments with diverse stimuli in
R&D. In addition to being a clean alternative, wind power is capable of producing
electricity at competitive prices relative to traditional sources of energy. The year 2016
was marked by the cost reduction of the offshore wind energy, in some circumstances,
this source becomes less expensive than onshore. Brazil does not yet have offshore wind
power plants and there are still few studies in this area. Thus, the objective of this study
was to map the existing technologies and technological trends of turbines for offshore
wind energy, exploring different rotor technologies and the structure of an offshore wind
turbine. The research was carried out in two stages: the theoretical basis, followed by a
patent analysis, enabling a technological mapping of the technologies. The patent base
Derwent Innovations Index (DII) was used and analyzed with a quantitative and
qualitative approach to patents from 1998 to 2018. It is concluded that offshore wind
turbines have almost twice the power than onshore turbines, the blades are reinforced
with glass fiber and the most commonly used foundation is the monopile. In the future,
turbines tend to increase further in power and size, it is expected that the materials used
in the blades will feature low density, high strength and can be recycled, and the towers
and foundations are in a hybrid trend of materials and model. In addition, there is a trend
in the development of technologies for turbines to be implemented in deeper water. |

In addition, there is a trend in the development of technologies for turbines to be implemented in deeper water. A energia dos ventos vem sendo utilizada desde o final do século XIX. Na Dinamarca, por exemplo, ocorreu o grande desenvolvimento da energia eólica a partir da fabricação das primeiras turbinas por pequenas empresas de equipamentos agrícolas. Por volta de 1980, países como Alemanha e EUA através de políticas de incentivo, desencadearam investimentos com diversos estímulos em pesquisa e desenvolvimento (P&D). Além de se tratar de uma alternativa limpa, a energia eólica é capaz de produzir eletricidade a preços competitivos com relação às fontes tradicionais de energia. O ano de 2016 ficou marcado pela redução do custo da fonte eólica offshore, em algumas circunstâncias, esta fonte torna-se menos custosa do que onshore. O Brasil ainda não possui usinas de energia eólica offshore e ainda são poucos os estudos nesta área. Assim, o objetivo deste estudo foi mapear as tecnologias existentes e as tendências tecnológicas de turbinas para energia eólica offshore, explorando diferentes tecnologias do rotor e da estrutura de uma turbina eólica offshore. A pesquisa foi realizada em duas etapas: a fundamentação teórica, seguida de uma análise de patentes, possibilitando um mapeamento tecnológico das tecnologias. Utilizou-se a base Derwent Innovations Index (DII) para a busca de patentes e essas foram analisadas com uma abordagem quantitativa e qualitativa desde 1998 até 2018. Como conclusão, cita-se que as turbinas eólicas offshore possuem quase o dobro de potência do que as turbinas onshore, apresentam pás com fibra de vidro e a fundação mais utilizada é a monopile. No futuro, as turbinas offshore tendem a aumentar ainda mais em potência e tamanho, espera-se que os materiais utilizados nas pás apresentarão características de baixa densidade, alta resistência e possam ser reciclados e as torres e as fundações estão com tendência híbrida de materiais e modelos. Além disso, nota-se uma tendência no desenvolvimento de tecnologias para as turbinas serem implementadas em águas com maior profundidade. 2019-08-05T22:24:35Z 2019-08-05T22:24:35Z 2019-02-25 masterThesis BARRETO, Fernanda de Melo.
