GWO – Blade Repair Training – 80h

Referencial: GWO BRT V3 2022.04.01 PT: O objetivo do Módulo de Reparação de Pás GWO é permitir aos participantes apoiar e cuidar de si próprios e de outros que trabalham na indústria eólica, possuindo os conhecimentos, aptidões e capacidades necessárias para a reparação de pás. EN: The aim of the GWO Blade Repair Module is to enable the participants to support and care for themselves and others working in the wind industry by possessing the necessary knowledge, skills, and ability for blade repair.

PT: Após a conclusão bem sucedida do curso de formação em reparação de pás, os participantes serão capazes de realizar e documentar uma inspeção das pás de uma turbina eólica, e executar trabalhos de reparação de acordo com uma instrução de trabalho, mantendo o perfil aerodinâmico e a integridade estrutural nas partes compostas reforçadas com fibra de vidro de uma turbina eólica dentro das seguintes dimensões: 1) reparações de laminados, incluindo reparações de bordos de ataque e de bordos de fuga que afetem uma quantidade máxima de 5 camadas e uma área máxima de reparação de 500cm2 2) substituição do material do núcleo até 200cm2 3) reparação de superfícies para pintura e gelcoat O curso de formação em reparação de lâminas GWO pretende ser um curso de nível básico, pelo que não se espera que os participantes realizem reparações nos principais elementos estruturais das lâminas, tais como peças sobressalentes, tampas de reserva e fibra de carbono. EN: Upon successful completion of the blade repair training course, the participants will be able to perform and document a wind turbine blade inspection, and execute repair work in accordance with a work instruction while maintaining the aerodynamic profile and structural integrity in glass fibre reinforced composite parts of a wind turbine within the following dimensions: 1) laminate repairs including leading edge and trailing edge repairs affecting a maximum amount of 5 layers and a maximum repair area size of 500cm2 2) core material replacement up to 200cm2 3) surface repair to paint and gelcoat The GWO blade repair training course is intended as an entry level course and the participants will not therefore be expected to perform repairs in major structural elements of blades like spars, spar caps and carbon fibre.
