Collaboration with Envision Energy
In FRECON, we have strong competencies within composite constructions and have provided support on a two-digit number of nacelle cover solutions to several of the largest wind turbine manufacturers.
In the collaboration with Envision Energy, we succeeded in transforming a basic nacelle cover design into a producible and functional cover with the correct strength to survive a “50 year storm”, and moreover with a strong focus on the customer’s total cost of ownership and specific customer requirements.
Envision Energy came up with an exciting, innovative, challenging, and aesthetic basic design that consisted of an eggshell form in solitary 3D surface. To mature this eggshell into a final nacelle cover, FRECON parameterized it. Such a complex 3D surface required the right qualified competencies, thus in FRECON we could benefit from our many years of experience in considerations of multiple and simultaneously parameters such as design requirements, functions, structural integrity, production, and cost price.
FRECON’s close and efficient integration method
By using FRECON’s methodological approach to construction work and our unique and effecient integration between design and calculation software, we could implement particularly many and fast iterations on optimizing of physical design and on the product’s structural properties. Hence, in this nacelle cover project, this method allowed us to utilize the double curved surfaces to quickly and efficiently give the nacelle cover more strength while at the same time reducing the material thickness.
“We managed to construct a nacelle cover with suitable draft angels and thus with an efficient moulding ejection. This gave Envision Energy a quick and smooth moulding, and a subsequent very simple assembly,” says Peter Laugesen, Lead Design Engineer i FRECON.
Today the nacelle cover can be seen on Envision Energy’s beautiful and innovative ‘Onshore Smart Wind Turbine 2.X MW’, which is known for providing maximum performance, optimizing energy yield, and minimizing downtime.
