O principal objetivo deste projeto passou pela modelação e dimensionamento de uma
bóia marítima energeticamente autossustentável que fosse capaz de fazer uma recolha e
transmissão de dados em alto mar e de produzir a eletricidade através de um aerogerador,
armazenando-a em baterias.
O aerogerador deve ter capacidade de produção suficiente para alimentar um equipamento
designado por Manta, um equipamento de recolha de dados que comunica remotamente
com vários operadores, que neste caso são UAV’s (Unmanned Aerial Vehicle) .
O rotor foi dimensionado propositadamente para este projeto utilizando estudos da velocidade
do vento em alto mar e teoremas aerodinâmicos. O aerogerador tem de produzir
eletricidade suficiente para alimentar a Manta e uma luz de sinalização, um total de 17W.
O aerogerador e a Manta estão instalados numa plataforma flutuante em alto mar. Esta
plataforma, com uma massa de 470 kg, foi dimensionada para ser estável e para conseguir
aguentar o peso da Manta e baterias (35 kg), do grupo gerador (6 kg) e da equipa que fosse
fazer a manutenção (decidido que seria cerca de 150 kg) quando necessário. Para além
da fonte de energia renovável foi também decidido que a plataforma seria construída com
um material sustentável, neste caso o CoreCork, um composto feito com cortiça e resinas
naturais.
Para que a plataforma fosse ainda mais sustentável em termos de materiais, a flutuação
será proveniente de câmaras-de-ar, com uma proteção em borracha reciclada, o mesmo
material do piso dos parques infantis. Neste projeto não foi efetuada uma estimativa de
custos financeiros.
O resultado final consiste no desenho de uma plataforma com a capacidade de produzir
energia elétrica própria, estável, para uso em alto mar e feita com materiais sustentáveis,
podendo a sua utilização explorada para outras atividades.
The main objective of this project was the design of an energetically self-sustaining sea buoy capable of collecting and transmiting data at high seas, and produce it´s own electrical energy using a wind turbine, storing the electricity in batteries. This wind turbine must have the capability of producing enough energy to feed an equipment called Manta, that collects data and comunicates remotely with diferente types of operators, in this case are UAV´s, and a signaling light, for a total of 17W . The wind turbine and the Manta will be installed on a floating plataform at high seas. This platform, that weighs 470kg, was dimensioned to be stable and to support the weigth of the Manta and batteries (35 kg), the wind generator (6 kg) and maintenence crew (decided to be about 150kg). Beside the platform having a renewable energy source it was also decided that it should be made of a sustainable material, in this case CoreCork, a compound made with cork and natural resins. In order for the platform to be even more sustainable in terms of materials, the buoyancy is to be provided by air tubes and it will have a side protection made of recycled rubber, the same material used on the floor of childrens playgrounds. In this project an estimate of cash costs was not made. With the conclusion of this project, it was obtained a model of a platform capable of producing it´s own energy, stable in high seas and made with sustainable materials, that can be used in others aplications.
