In a perfect world all complex repair jobs would be done on the ground, but when you are repairing wind turbines, that’s not possible. So with a worldwide problem of turbine blades delaminating, and the glue used to repair the fibreglass refusing to stick due to the atmospheric conditions, our client needed a solution allowing the repairs to be made.
Our client needed a workstation allowing them to carry out repairs up to 100m in the air, and the glue used to repair the blades is very toxic. It needed to supply a controlled humidity environment and fresh air. It had to be lightweight to stay within the load limits of a crane lifting it 100m in the air.
The client did not have a design or solutions to creating an airtight seal around the turbine which vary in thickness over a 52m length.
We designed a “habitat” for staff to be sealed inside – along with a section of the the blade needing repairs – creating a controlled temperature and humidity environment. Complying with international health and safety standards, this enclosure had to adapt to many different environmental situations.
